Maintenance work
Belt tension of the spindle drives
Care must be taken to ensure that the belt is
always correctly tensioned. An incorrectly
tensioned belt can result in damage to the machine
and/or tools.
The belt tension must be checked every week or
when changing belts and the belt retensioned if
necessary.
• Make two marks 200 mm apart on the
untensioned belt.
• Tension the belt and check the elongation.
Horizontal spindles:
• Release clamping screws on motor.
• Insert wrench (1) in housing, fit ratchet (2) in
wrench and tension belt.
• Retighten clamping screws on motor.
Vertical spindles:
The belt is tensioned continuously by a
spring tensioner.
• Remove cover on front of machine in order to
reach the spring tensioner when changing belts.
