General Operation
,
continued
PROBLEM SOLUTION
The machine buzzes.
Use extreme care when servicing solenoids. The
surfaces can be very hot and a severe pinching hazard
exists under the solenoid cover.
One or more of the solenoids that operate the Vac Head,
buffer brush, and oil transfer roller may not be fully engaged.
You may be able to locate the buzzing solenoid by feeling
NEAR
the solenoids; a solenoid that is not engaging will feel
hot.
Solenoids that do not fully engage are usually out of
alignment. If you find a misaligned solenoid, loosen the
adjustment screws, realign the solenoid, and tighten the
screws.
It is also possible that oil or debris has gotten on the
solenoid shaft and it is preventing the solenoid from
engaging. Wipe the solenoid shaft with a clean, dry cloth.
If the solenoid continues to buzz or feel hot, replace it.
Refer to the Parts section for part numbers.
Cleaning Operation
PROBLEM SOLUTION
None of the nozzles are
spraying cleaner.
1. Make sure the cleaning operation is selected.
2. Ensure there is cleaner in the cleaner tank.
3. Clean the in-line filter. Refer to the Maintenance section
for instructions about how to clean the in-line filter.
4. Adjust the cleaner flow at the flow control bypass valve
to dispense more cleaner by turning it
clockwise
in
small increments until cleaner begins spraying. Refer to
drawing 294-115-032, View A (located in the Parts
section) to locate the flow control bypass valve.
