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 like you would 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 that the clutch clicks at least
five times to verify maximum
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.
