Repair Guide
IMPORTANT: Make sure the machine is unplugged before the removal of any
electrical parts
.
Removal of Cleaning Head:
1. First, unscrew the head in the same direction it turns
during operation (or clockwise when looking from the
underside).
2. Once you have loosened the assembly, spin if off
with your hands. If the cleaning head is difficult to
remove, you may use a ¾” socket wrench on the
exposed center nut.
Replacing the Felt Seal:
A worn or “dried out” felt will not form a proper vacuum seal. This will impair the
extraction capabilities of the unit. Therefore, the carpets are left more wet than is
desirable.
1. Remove cleaning head assembly.
2. Make sure felt is saturated with oil to insure a proper seal.
3. Remove and reverse seal so that “new” face is against hub.
NOTE: Alternating sides will temporarily extend the life of the felt.
However, the seal may need to be replaced.
4. Reinstall head assembly.
NOTE: When reinstalling the head assembly, you should be able to “feel” the
felt compacting against the seal plate during the last quarter rotation of the
head.
Removal of Vacuum Motor:
1. Disconnect machine from power source.
2. Remove hose from end of vacuum motor.
3. Remove ¼-20 screws from the vacuum motor.
4. Lift motor.
5. Disconnect wires at terminal clips.
Removal and Re-Installation of Solution Pump:
1. Disconnect machine from power source.
2. Check that all water has been evacuated from unit.
3. Disconnect ½” hoses on either side of pump.
4. Remove four (4) 10-24 screws and nuts mounting pump to side of frame.
