AN AUTHORIZED SERVICE CENTER SHOULD PERFORM THE FOLLOWING PROCEDURES:
Drive Belt Adjustment and/or Replacement:
The cogged belt drive system rarely requires tightening. If the belt becomes loose from wear, it is time to replace it.
Follow this procedure: Remove acorn nut and thru-bolt from brush chassis lift handle. Gently tilt machine backwards. While
holding the base of the brush housing with one hand, release the lift handle from the up/locked position. The brush housing
pivots on a hinge that doesn't need to be removed. Loosen the two motor bracket mounting bolts with a 7/16" wrench. DO
NOT REMOVE THE BOLTS UNLESS YOU ARE REPLACING THE MOTOR. Slide the motor away from the brush to
tighten the belt or toward the brush to remove. If you are replacing the belt it will be necessary to remove the brush assembly
to install a new one. Remove the two axle shaft retaining screws located on either side of the brush housing. Loop belt over
cog and reinstall brush.
Unlike a "V" type belt, the cogged belt is run with basically zero deflection. To test the belt tension, hold the belt between your

thumb and forefinger and twist to the side. It should turn approximately 90
with little effort. If it twists more than 90
,
retighten the belt.
Additional service information is available from your local Pacific Steamex Distributor or through our Technical Service Department.
