Checking the height adjustment

A
➢ Perform a visual inspection of height adjustment motor (A) and
spindle (B) for abrasion.
If significant abrasion is present:
Replace the height adjustment motor including spindle [ → 337].
➢ Use the Up/Down keys on the touchscreen to move the unit up and
down through its entire adjustment range.
If the mechanics of the height adjustment is defective, a speed-
dependent hammering noise may occur which points to bearing
damage at the height adjustment motor.
If a hammering noise occurs:
Replace the height adjustment motor including spindle [ → 337].
If the unit is not used for a longer period of time, a slight jolt may occur the
first time it starts moving. However, the next time it starts moving, it must
execute a jolt-free soft start.
➢ Use the Up/Down keys on the control panel to move the unit and
observe the movement of the slide. The slide must start in gentle
starting and then change over to a faster movement.
If the height adjustment cannot be correctly positioned in detail using
the gentle start:
Lubricate the spindle with a light coat of Chesterton 622.
