Adjusting Cutterhead Guard Tension

!WARNING The cutterhead guard is a critical safety feature. If it has been removed, you MUST install and verify its operation before using machine! Failure to properly install this guard will greatly increase the risk of serious personal injury. If the spring has lost factory-set tension, it MUST be reset for the guard to function properly.

Items Needed

• Heavy Leather Gloves ........ 1 Pair
• Hex Wrenches 3, 6mm ........ 1 Ea.
• Straight Jaw Pliers 10" ........ 1

To adjust cutterhead guard tension:

1. DISCONNECT MACHINE FROM POWER!

2. Loosen fence lock, move fence all the way back, then tighten fence lock.

3. Pull cutterhead guard back and let it go. It should spring back over cutterhead and rest against fence (see Figure 1).

   — If cutterhead guard does spring back over cutterhead and rest against fence, cutterhead guard is properly tensioned. Proceed to Step 7.

   — If cutterhead guard does not spring back over cutterhead and rest against fence, proceed to Step 4.

5. With cutterhead guard resting against fence, use straight-jaw pliers to rotate cutterhead guard clamp a 1/4 turn clockwise, then tighten cap screw to secure guard clamp, as shown in Figure 3.

Figure 3. Rotating cutterhead guard clamp (tables removed for clarity).

6. Pull cutterhead guard back and let it go. It should spring back over cutterhead and rest against fence.

— If cutterhead guard does spring back over cutterhead and rest against fence, cutterhead guard is properly tensioned. Proceed to Step 7.

— If cutterhead guard does not spring back over cutterhead and rest against fence, repeat Steps 4–5 until properly adjusted, then proceed to Step 7.

7. Verify cutterhead guard height is as low as possible (approximately 1/8" above infeed table) without dragging on infeed table/rabbeting extension.

— If cutterhead guard is as low as possible without dragging on infeed table/rabbeting extension, cutterhead guard height is correct. No further adjustment is required.

— If cutterhead guard is not as low as possible or drags on infeed table/rabbeting extension, loosen set screw securing cutterhead guard shaft, position cutterhead guard until it is approximately 1/8" above infeed table, then tighten set screw (see Figure 4).

INTRODUCTION

Machine Description

A jointer is used to flatten the face or edge of a workpiece, which is required when properly "squaring up" a workpiece for later construction or jointing. A jointer can also cut bevels, rabbets, and other specialized cuts with various jigs or fixtures.

A typical cut on a jointer is made by firmly holding a workpiece against the infeed table and fence, then moving the workpiece over the cutterhead while using the fence as a guide. As the workpiece moves over the cutterhead, the knives or inserts make many shallow cuts that "shave" off the surface of the workpiece. Since only a small amount of the workpiece is removed during a jointer cut, most jointer cuts are repeated many times to yield a desired result.

The Model G0490 has a 4-knife cutterhead and the Model G0490X has a spiral cutterhead with 40 indexable inserts.

WARNING For Your Own Safety Read Instruction Manual Before Operating Jointer a) Wear eye protection. b) Always keep cutterhead and drive guards in place and in proper operating condition. ALWAYS replace cutterhead guard after rabbeting operations. c) Never make jointing or rabbeting cuts deeper than 1/8" or planing cuts deeper than 1/16" d) Always use hold-down or push blocks when jointing material narrower than 3" or planing material thinner than 3". e) Never perform jointing, planing, or rabbeting cuts on pieces shorter than 10" in length.

Controls & Components

Refer to Figures 1–3 and the following descriptions to become familiar with the basic controls of this machine.

Figure 1. STOP/START button locations.

START Button: Starts motor only if the STOP button is in the out position.

STOP Button: Stops motor when pushed in and disables the START button. Enable the START button by twisting the STOP button clockwise until it springs forward in the out position.

Table Movement: To move the infeed table, loosen the table lock (see Figure 2), position the table with the table adjustment lever in the preset range, then tighten the table lock. The outfeed table is preset with no range of movement allowed, so if it gets accidentally unlocked it will not move.

Figure 2. Locations of table locks and levers.

Fence Movement: The fence has a lock that keeps it in position (see Figure 3). To move the fence, loosen the lock and slide the fence where needed.

Figure 3. Locations of fence controls.

Fence Tilting: The tilt lock (see Figure 3) secures the fence at any position in the available range. The plunger locks into an indexing ring to easily set the fence tilt to 90° after moving it. Two positive stops enable the fence to be positioned at 45° inward and 45° outward for common 45° bevel cuts. Even when the fence is resting against the fence stops, the tilt lock must be tightened before cutting.

OWNER’S MANUAL. Read and understand this owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed. Only allow trained/supervised people to use this machine. When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make your workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use machinery in areas that are wet, cluttered, or have poor lighting. Operating machinery in these areas greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental alertness is required for safe operation of machinery. Never operate under the influence of drugs or alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You can be shocked, burned, or killed by touching live electrical components or improperly grounded machinery. To reduce this risk, only allow qualified service personnel to do electrical installation or repair work, and always disconnect power before accessing or exposing electrical equipment.

DISCONNECT POWER FIRST. Always disconnect machine from power supply BEFORE making adjustments, changing tooling, or servicing machine. This prevents an injury risk from unintended startup or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved safety glasses or a face shield when operating or observing machinery to reduce the risk of eye injury or blindness from flying particles. Everyday eyeglasses are NOT approved safety glasses.

⚠WARNING

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine for damaged, loose, or mis-adjusted parts—or any condition that could affect safe operation. Immediately repair/replace BEFORE operating machine. For your own safety, DO NOT operate machine with damaged parts!

Additional Safety for Jointers

⚠WARNING

Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutterhead or other moving components! Flying chips can cause blindness or eye injuries. Workpieces or inserts/knives thrown by cutterhead can strike nearby operator or bystanders with deadly force. To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.

KICKBACK. Occurs when workpiece is ejected from machine at a high rate of speed. To reduce the risk of kickback-related injuries, use quality workpieces, safe feeding techniques, and proper machine setup or maintenance.

GUARD REMOVAL. Operating jointer without guard exposes operator to knives/inserts. Except when rabbeting, never remove guards for regular operations or while connected to power. Turn jointer OFF and disconnect power before clearing any shavings or sawdust from around cutterhead. After rabbeting or maintenance is complete, immediately replace all guards and ensure they are properly adjusted before resuming regular operations.

DULL/DAMAGED KNIVES/INSERTS. Dull knives/inserts can increase risk of kickback and cause poor workpiece finish. Only use sharp, undamaged knives/inserts.

OUTFEED TABLE ALIGNMENT. Setting outfeed table too high can cause workpiece to hit table and get stuck, increasing risk of kickback. Setting outfeed table too low may cause workpiece to become tapered from front to back. Always keep outfeed table even with knives/inserts at top dead center (highest point during rotation).

INSPECTING STOCK. Impact injuries or fire may result from using poor workpieces. Thoroughly inspect and prepare workpiece before cutting. Verify workpiece is free of nails, staples, loose knots or other foreign material. Workpieces with minor warping should be surface planed first with cupped side facing infeed table.

GRAIN DIRECTION. Jointing against the grain or end grain can increase the risk of kickback. It also requires more cutting force, which produces chatter or excessive chip out. Always joint or surface plane WITH the grain.

MAXIMUM CUTTING DEPTH. To reduce risk of kickback, never cut deeper than 1/8" per pass.

CUTTING LIMITATIONS. Cutting a workpiece that does not meet the minimum dimension requirements can result in breakup, kickback, or accidental contact with cutterhead during operation. Never perform jointing, planing, or rabbeting cuts on pieces smaller than 8" long, 3/4" wide, or 1/4" thick.

PUSH BLOCKS. Not using push blocks when surface planing may result in accidental cutterhead contact. Always use push blocks when planing materials less than 3" high or wide. Never pass your hands directly over cutterhead without a push block.

WORKPIECE SUPPORT. Loss of workpiece control while feeding can increase risk of kickback or accidental contact with cutterhead. Support workpiece continuously during operation. Position and guide workpiece with fence. Support long or wide stock with auxiliary stands.

FEED WORKPIECE PROPERLY. Kickback or accidental cutterhead contact may result if workpiece is fed into cutterhead the wrong way. Allow cutterhead to reach full speed before feeding. Never start jointer with workpiece touching cutterhead. Always feed workpiece from infeed side to outfeed side without stopping until cut is complete. Never back work toward infeed table.

SECURE KNIVES/INSERTS. Loose knives or improperly set inserts can become dangerous projectiles or cause machine damage. Always verify knives/inserts are secure and properly adjusted before operation. Straight knives should never project more than 1/8" (0.125") from cutterhead body.
