Routine Maintenance (Cont.)
Drum pulleys and motor pulleys
Réglage des roues (suite)
Regularly check that the groove (A) of the pulley has not sunk, otherwise the belt (B) will operate on the
bottom (C) of the pulley itself.
Bearings
Réglage des roues (suite)
Check bearings regularly for wear or damage according to the following timescales:
Wheels:
Fan Shaft:
Sanding Drum:
Motor Shaft:
Excessive belt tension may cause the premature failure of the ball bearings. The drum belt must
have a 10.5 mm stretch with a center load of 30±3 N.
Pulleys with sunken grooves cause the belts to slip and the correct power will not be transferred
to the drum/suction pipe.
This situation can easily occur if the machine loses power during operation. They should therefore
be replaced.
