Just finished assembly of my new 14-651 Delta mortiser. Amazon $249.00
-$25.00 (purchase of 150 or more) - $50.00 Delta rebate, free shipping. Question is about the Hydraulic cylinder that mounts on studs between the base and carriage. Is the purpose of it to raise the motor to the top or just counter balance it so it doesn't drop on it's own? Mine doesn't automatically raise the motor when I let go of the handle and I'm wondering if I have a bad part. In fact the motor assembly is suprisingly hard to re-raise. The further I lower it, the harder it is to raise. Thanks, Mike
