REPAIR GUIDE
FOR SAFETY: When servicing machine, unplug
cord from wall outlet.
REMOVAL OF CLEANING HEAD
1. Unscrew the head in the same direction it turns
during operation. This is clockwise when looking
from the underside).
FOR SAFETY: Be certain machine is on its right
side. Otherwise oil will drain from the vent in the
gearbox.
2. Once the assembly is loose, spin it off by hand. If
the cleaning head is difficult to remove, 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.
1. Remove cleaning head assembly
2. Make sure the felt is saturated with oil to insure a
proper seal.
3. Remove and reverse seal so that the “new” face
is against the 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, the felt should compress
against the seal plate during the last quarter
rotation of the head. If this can not be felt, the
seal may need replacement.
STORING MACHINE
1. Before storing machine, be certain to drain and
rinse tanks of all water.
2. Store machine in a dry area in the upright position.
3. Open recovery tank lid to promote air circulation.
4. If storing in cold climate, freeze protect.
ATTENTION: Do not expose to rain. Store
indoors.
ATTENTION: If storing machine in freezing
temperatures, be sure that machine and solution
system are completely drained and dry.
