Please read and follow the “MAINTENANCE SCHEDULE” located under the recovery tank.
At the end of the day’s operation, the machine should be completely cleaned and prepared for the next shift’s operations. Careful maintenance will insure effective
performance throughout a long period of service.

DRIVE MOTOR CHAIN ADJUSTMENT
To adjust the tension of the chain, first loosen the adjustment screw’s jam nut (Figure 6). Next, turn the adjustment screw clockwise to tighten the chain and
counterclockwise to loosen. A properly adjusted chain should have a 1/2 inch of slack. When the chain is properly adjusted, retighten the jam nut.
NOTE: Excessive chain tension may cause damage to the bearings, sprockets, or chain.

SQUEEGEE TILT ADJUSTMENT
The squeegee on this machine pivots freely, allowing the pressure on each end of the squeegee to keep it level with the floor at all times. The front to rear tilt adjustment
is correct if, as the machine is moved forward, there is an equal amount of squeegee flare at the ends of the squeegee rubber compared to the center.
To adjust the tilt of the squeegee, turn the tilt adjustment screw which can be found on the squeegee bar just in front of the squeegee height adjustment knob (Figure
7). Turn the screw clockwise to tilt the ends of the squeegee upward and counterclockwise to turn the ends downward.

SQUEEGEE HEIGHT ADJUSTMENT
In order for the squeegee to pick up effectively, the height must be adjusted to give the correct amount of squeegee rubber contact with the floor. If the squeegee
is too high or too low it will not pick up properly.
To adjust the height of the squeegee relative to the floor, turn the height adjustment knob (Figure 7) clockwise to lower the squeegee and increase pressure on the
squeegee blades. To raise the squeegee and reduce pressure on the squeegee blades, turn the knob counterclockwise to the desired height. Refer to Figure 8 for
the correct height adjustment for the squeegee.
