Grizzly G1018HW owner's manual: Section 6: operations

SECTION 6: OPERATIONS

Your safety is important! Please follow the warnings below during this entire section:

WARNING Operating this equipment creates the potential for flying debris to cause eye injury. Always wear safety glasses when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI).

WARNING Keep loose clothing out of the way of machinery and keep hair pulled back during operations.

CAUTION Using this machine produces sawdust that may cause short and long-term respiratory illness. Always wear a dust mask when operating this machine.

Stock Inspection & Requirements

Here are some rules to follow when choosing and cutting stock:

• If the stock has large or loose knots, find another workpiece. Knots in a workpiece can be dangerous to the operator, as well as destructive to equipment.
• When jointing, always cut WITH the grain rather than AGAINST it. Cutting against the grain (going against the pattern of the wood's growth rings) chips the wood instead of cutting it, making the workpiece rough and irregular and increasing the chances that a kick-back will occur.

To check the grain direction, look at the side of your board. If the direction of the grain structure facing the cutterhead runs toward the cutterhead as it sits on the infeed table, your cut will be WITH the grain. See Figure 43.

CORRECT ROTATION OUTFEED TABLE INFEED TABLE FEED DIRECTION

INCORRECT ROTATION OUTFEED TABLE INFEED TABLE FEED DIRECTION

Figure 43. Correct and incorrect grain alignment to cutterhead.

• Make sure that any stock you process with the jointer is clean and free of any dirt, nails, staples, tiny rocks or any other foreign objects that may damage the jointer blades.

• Only process natural wood fiber through your jointer. Never joint MDF, particle board, plywood, laminates or other synthetically made materials.

• Make sure any stock you joint is properly dried. Wood with a moisture content over 20% will cause unnecessary wear on the knives and will produce undesirable results.

NOTICE Occasionally, you will find woods that defy all rules. In those rare cases, it is best to feed the workpiece slowly and take several shallow cuts. A few extra passes will hurt much less than a ruined workpiece.

Squaring Stock

The jointer performs two of the four required operations for squaring up stock—surface planing and edge jointing. To help you understand these two operations better, we quickly describe the squaring process below:

Step 1. Surface plane the concave face with a JOINTER to make it flat.

Step 2. Edge joint the best edge with a JOINTER to make it flat.

Step 3. Plane the second face with a THICKNESS PLANER to make it parallel to the first face.

Step 4. Rip the second edge with a TABLE SAW to make it parallel to the first edge.

G0500/G1018/G1018HW 8" Jointers -29-

Surface Planing

The purpose of surface planing is to make a flat face on a piece of stock to prepare it for planing on a thickness planer. See Figure 44.

Figure 44. Illustration of surface planing effects.

NOTICE

If you are not experienced with a jointer, set the depth of cut to 0", and practice feeding the workpiece across the tables as described below. This procedure will better prepare you for the actual operation.

To surface plane on the jointer:

1. Make sure that you have read and understand all safety instructions in Section 1: Safety and that your stock has been inspected for safe operation as described in the "Stock Inspection" instructions earlier in this section.

2. Make sure your workpiece is within the minimum and maximum stock dimensions that your Grizzly 8" Jointer can safely process. (Check the data sheet in the back of this manual for your particular model.)

3. Set the cutting depth for your operation. (We suggest 1/32" for surface planing, using a more shallow depth for harder wood species or for wider stock.)

4. Make sure your fence is set to 90°

5. If your workpiece is cupped (warped), place it so the concave side is face down on the surface of the infeed table.

6. Start the jointer.

7. With a push block in each hand, press the workpiece against the table and fence with firm pressure.

8. Feed the workpiece over the cutterhead as shown in Figure 45. Note—When your leading hand (with push block) gets within 4" of the cutterhead, lift it up and over the cutterhead, and place the push block on the portion of the workpiece that is over the outfeed table. At this point, focus your pressure on the outfeed end of the workpiece while feeding, and repeat the same action with your trailing hand when it gets within 4" of the cutterhead. To keep your hands safe, DO NOT let them get closer than 4" from the cutterhead when it is moving!

9. Repeat steps 7-8 until the entire surface is flat.

Figure 45. Surface planing the face of a workpiece.

Edge Jointing

The purpose of edge jointing is to produce a finished, flat-edged surface that is suitable for joinery or finishing. It is also a necessary step in the squaring process of rough or warped stock. See Figure 46.

Figure 46. Illustration of edge jointing effects.

NOTICE

If you are not experienced with a jointer, set the depth of cut to 0", and practice feeding the workpiece across the tables as described below. This procedure will better prepare you for the actual operation.

To edge joint on the jointer:

1. Make sure that you have read and understand all safety instructions in Section 1: Safety and that your stock has been inspected for safe operation as described in the "Stock Inspection" instructions earlier in this section.

2. Make sure your workpiece is within the minimum and maximum stock dimensions that your Grizzly 8" Jointer can safely process. (Check the data sheet in the back of this manual for your particular model.)

3. Set the cutting depth for your operation. (We suggest between 1/4" and 1/8" for edge jointing, using a more shallow depth for harder wood species or for wider stock.)

4. Make sure the fence is set to 90°.

5. If your workpiece is cupped (warped), place it so the concave side is face down on the surface of the infeed table.

6. Start the jointer.

7. Press the workpiece against the table and fence with firm pressure. Use your trailing hand to guide the workpiece through the cut.

8. Feed the workpiece over the cutterhead as shown in Figure 47. Note—If your leading hand gets within 4" of the cutterhead, lift it up and over the cutterhead, and place it on the portion of the workpiece that is over the out-feed table. At this point, focus your pressure on the outfeed end of the workpiece while feeding, and repeat the same action with your trailing hand when it gets within 4" of the cutterhead. To keep your hands safe, DO NOT let them get closer than 4" from the cutterhead when it is moving!

9. Repeat steps 7-8 until the entire edge is flat.

Bevel Cutting

The purpose of bevel cutting is to cut a specific angle into the edge of a workpiece. See Figure 48.

The Grizzly 8" Jointers have preset fence stops at 45° to the left and 45° to the right. If your situation requires a different angle, the preset fence stops can be easily adjusted for your needs.

Figure 48. Illustration of bevel cutting effects.

NOTICE

If you are not experienced with a jointer, set the depth of cut to 0", and practice feeding the workpiece across the tables as described below. This procedure will better prepare you for the actual operation.

To bevel cut on the jointer:

1. Make sure that you have read and understand all safety instructions in Section 1: Safety and that your stock has been inspected for safe operation as described in the "Stock Inspection" instructions earlier in this section.
2. Make sure your workpiece is within the minimum and maximum stock dimensions that your Grizzly 8" Jointer can safely process. (Check the data sheet in the back of this manual for your particular model.)
3. Set the cutting depth for your operation. (We suggest between 1/16" and 1/8" for bevel cutting, using a more shallow depth for harder wood species or for wider stock.)
4. Make sure your fence is set to the angle of your desired cut.
5. If your workpiece is cupped (warped), place it so the concave side is face down on the surface of the infeed table.
6. Start the jointer.
7. With a push block in your leading hand, press the workpiece against the table and fence with firm pressure.
8. Feed the workpiece over the cutterhead as shown in Figure 49. Note—If your leading hand gets within 4" of the cutterhead, lift it up and over the cutterhead, and place the push block on the portion of the workpiece that is over the outfeed table. At this point, focus your pressure on the outfeed end of the workpiece while feeding, and repeat the same action with your trailing hand when it gets within 4" of the cutterhead. To keep your hands safe, DO NOT let them get closer than 4" from the cutterhead when it is moving!
9. Repeat steps 7-8 until the angled cut is satisfactory to your needs.

Figure 49. Bevel cutting with the fence at 45°.

Rabbet Cutting

The purpose of rabbet cutting is to remove a section of the workpiece edge. When combined with another rabbet cut edge, the rabbet joints create a simple, yet strong method of joining stock. See Figure 50.

Figure 50. Illustration of rabbet cutting effects and a few sample joints.

NOTICE If you are not experienced with a jointer, set the depth of cut to 0", and practice feeding the workpiece across the tables as described below. This procedure will better prepare you for the actual operation.

To rabbet cut on the jointer:

1. Make sure you have read and understand all safety instructions in Section 1: Safety and that your stock has been inspected for safe operation as described in the "Stock Inspection" instructions earlier in this section.
2. Make sure your workpiece is within the minimum and maximum stock dimensions that your Grizzly 8" Jointer can safely process. (Check the data sheet in the back of this manual for your particular model.)
3. If your workpiece is cupped (warped), it should be straightened out before you attempt to make a rabbet cut.
4. Set the cutting depth for your operation. (We suggest between 1/16" and 1/8" for rabbet cutting, using a more shallow depth for harder wood species or for wider stock.)
5. Make sure your fence is moved forward, so the amount of infeed/outfeed table exposed is the same as the size of your rabbet. Also, make sure your fence is set to 90°
6. Start the jointer.
7. With a push block in each hand, press the workpiece against the table and fence with firm pressure.
8. Feed the workpiece over the cutterhead as shown in Figure 51. Note—When your leading hand gets within 4" of the cutterhead, lift it up and over the cutterhead, and place the push block on the portion of the workpiece that is over the outfeed table. At this point, focus your pressure on the outfeed end of the workpiece while feeding, and repeat the same action with your trailing hand when it gets within 4" of the cutterhead. To keep your hands safe, DO NOT let them get closer than 4" from the cutterhead when it is moving!
9. Repeat steps 7-8 until the your rabbet is cut to depth.

SECTION 7: MAINTENANCE

! WARNING Disconnect power to the machine when performing any adjustments or maintenance. Failure to do this may result in serious personal injury.

General

Regular periodic maintenance on your Grizzly 8" jointer will ensure its optimum performance. Make a habit of inspecting your jointer each time you use it. Check for the following conditions and repair or replace when necessary.

1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Damaged V-belt.
5. Any other condition that could hamper the safe operation of this machine.

Table

The table and other non-painted surfaces on your Grizzly 8" Jointer should be protected against rust and pitting. Wiping the table clean after every use ensures that moisture from wood dust does not remain on bare metal surfaces.

Tables can be kept rust-free with regular applications of products like SLIPIT® or Boeshield® T-9. For long term storage you may want to consider products like Kleen Bore's Rust Guardit™.

Lubrication

Since all bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. DO NOT lubricate them. Table ways and the fence assembly should not be lubricated. If the tables appear to be stuck, disassemble and clean any foreign materials from the ways. Re-assemble and reset the gibs.

V-Belt

Inspect regularly for tension and wear. Check the V-belt tension by squeezing them in the center. If you can squeeze them more than 1/2" on both sides, using moderate pressure, then they need to be tightened. Check pulleys to ensure that they are properly aligned. To replace or adjust the V-belts, see Section 8: Service Adjustments.

Knife Condition

Using sharp knives is one of the most important factors involved with the operation of the jointer. A good maintenance procedure is to hone the knives to keep them in top shape. A knife hone will polish and finely sharpen jointer knives quickly and easily without removing them.

For damaged or extra dull knives, have them resharpened by a professional grinder. To avoid downtime from resharpening, we recommend having an extra set of knives on hand.

SECTION 8: SERVICE ADJUSTMENTS

!WARNING Disconnect power to the machine when performing any adjustments or maintenance. Failure to do this may result in serious personal injury.

About Service

This section is designed to help the operator with adjustments that were made at the factory and might also need to be made during the life of the machine.

This section is provided for your convenience—it is not a substitute for the Grizzly Service Department. If any adjustments arise that are not described in this manual, then feel free to call the Grizzly Service Department.

Similarly, if you are unsure of how to perform any procedure in this section, the Grizzly Service Department will be happy to guide you through the procedures or help in any other way.

Setting Knives

Setting the knives correctly is crucial to the proper operation of the jointer and is very important in keeping the knives sharp. If one knife is higher than the others, it will do the majority of the work, and thus, dull much faster than the others.

The knives on your Grizzly 8" Jointer should be set .051" (1.3MM)-.060" (1.5MM) higher than the cutterhead. The knife jig included with the jointer is designed to set the knives within this height.

The Grizzly 8" Jointers come with both jack screws and springs to provide you with two options for cutterhead adjustments (see Figure 52). Note—Only one of these options is needed to set the knives—see step 5* for clarification.

Figure 52. Cutterhead profile.

To set the knives:

1. Disconnect the jointer from the power source!
2. Remove the cutterhead guard from the table and lower the infeed and outfeed tables as far as they go. This will give you unrestricted access to the cutterhead.
3. Remove the belt guard to expose the cutterhead pulley.
4. Rotate the cutterhead pulley to give you good access to one of the cutterhead knives.
5. Loosen the cutterhead gib bolts, starting in the middle, and alternating back and forth until all of the gib bolts are loose, but not falling out.

*Note—If this is the first time you are setting the knives, remove the gib and knife from the cutterhead. Decide which adjustment option you are going to use between the jack screws and the springs. If you decide to use

-36- G0500/G1018/G1018HW 8" Jointers

the jack screws, remove the springs from the cutterhead. If you decide to use the springs, you can just thread the jack screws completely into the cutterhead so they will not get lost. Replace the gib and knife.

6. Position the knife gauge over the knife as shown in Figure 53 and loosen the gib bolts until the knife is completely loose.

Figure 53. Jig placement on cutterhead.

7. Jack Screws—Using a 3MM allen wrench, find the jack screws through the access holes in the cutterhead (Figure 54) and rotate the jack screws to raise or lower the knife. When the knife is set correctly, it will barely touch the middle pad of the knife setting jig. Snug the gib bolts tight enough to just hold the knife in place. Repeat steps 5-7 with the rest of the knives.

Figure 54. Jack screw access hole.

Springs—Push the knife down with the jig so that the knife edge is touching the middle pad of the jig. Hold the jig down and tighten the gib bolts just tight enough to hold the knife in place. Repeat steps 5-7 with the rest of the knives.

8. Rotate the cutterhead to the first knife you started with. Slightly tighten all the gib bolts, starting at the ends and working your way to the middle by alternating left and right. Repeat this step on the rest of the knives.

9. Repeat step 8.

10. Repeat step 8, but final tighten each gib bolt.

Adjusting Gibs

The function of the table gibs (shown in Figure 55) is to eliminate excessive play in the table movement. The gibs also control how easy it will be to move the tables up and down.

Figure 55. Table gibs.

To adjust the table gibs:

1. Loosen the table lock.

2. Loosen the lock nuts and setscrews shown in Figure 56 on the next page. Make sure you support the table as you loosen it to prevent it from dropping to the end of its travel.

Figure 56. Table gib lock nuts and setscrews.

5. Evenly tighten both gib setscrews a small amount, then check the table by moving it up and down. Adjust the setscrews as needed until the friction of the table movement is balanced between minimal play and ease of movement. Note—Tighter gibs reduce play but make it harder to adjust the tables.

6. Repeat steps 1-5 with the other table.

7. Adjust the table height of both tables before resuming with any operations.

Adjusting V-Belts

In order for your jointer to perform at its best, you should check (and adjust if necessary) the V-belt tension and alignment.

To adjust the V-belt tension:

1. Disconnect the jointer from the power source!

2. Remove the stand door to gain access to the V-belts.

3. Loosen the motor adjustment bolts shown in Figure 57.

Figure 57. Motor adjustment bolts (shown underneath stand for clarity).

4. Push down on the motor with one hand and tighten the motor adjustment bolts with the other hand.

5. Check the V-belt tension by squeezing them in the center, as shown in Figure 58. If you can squeeze the V-belts more than 1/2" on both sides, using moderate pressure, then they need to be tighter—repeat steps 3-5.

6. When the V-belt tension is correct, replace the stand door.

Replacing V-Belt

During the life of your jointer, you will need to replace the V-belts when they become cracked or damaged.

To replace the V-belts:

1. Disconnect the jointer from the power source!
2. Remove the stand door to gain access to the V-belts.
3. Loosen the motor adjustment bolts shown in Figure 60.

Figure 58. Checking V-belt tension.

To adjust the V-belt alignment:

1. Disconnect the jointer from the power source!
2. Remove the stand door to gain access to the V-belts.
3. Loosen the motor mount bolts shown in Figure 59.

Figure 60. Motor adjustment bolts (shown underneath stand for clarity).

4. Move the motor up to loosen and remove the V-belts from the motor and cutterhead pulleys.
5. Install the new V-belts on the motor and cutterhead pulleys.
6. Adjust the V-belts to their proper tension.
7. Replace the stand door.

Figure 59. Motor mount bolts(shown underneath stand for clarity).

4. Use a straightedge to align the motor and cutterhead pulleys.
5. Tighten the motor mount bolts. Note—Minor alignment changes can be made by loosening the setscrew on the pulleys and adjusting them on their shaft. Replace the stand door.
