Head

Rollers

Checking the head pressure is very easy using a standard bathroom

scale.

1. Before starting, make sure that the sliding plate is moved all the

way to the far side of the machine and is out of the way of the

scale.

2. Place the scale on the traction drive exactly like a regular

workpiece. Orient the scale so that the measurement display is

facing the keypad and position the top head rollers (mounted on

the underside of the head) directly over the scale footpads.

3. Crank the head down and make sure to rotate the crank at least

two revolutions after the clicking begins to verify proper loading.

4. Read the scale measurement and repeat several times. The

proper head loading should be between 75 and 85 pounds.

If the head loading is not within these bounds the most likely caused by

insufficient lubrication of the four vertical corner posts or the two

vertical leadscrews. Wipe all residue off these parts and apply a thin

film of White Lithium Grease to each. Crank the head up and down

several time so as to spread the grease evenly along the parts. If this

condition persists please contact CompuCarve help services to

address the issue further.

• Removing a Stuck Bit: If unable to remove the bit and adapter from

the quick change use the bit removal tool in the manner described in

Bit assembly Removal section.

Do not leave bit and adapter assembled in the quick release

chuck when not in use. The adapter can rust to the quick

release chuck if left installed for an extended period of time.
