VAC SHUT OFF
The TruckForce utilizes a ball float shutoff system, which
shuts off the flow to the vacuum motors when solution
reaches the appropriate level to activiate the ball shutoff. This
shutoff has been designed to protect the vacuum motors from
excess water entering the vacuum motors
provided that the
owner is utilizing a defoamer chemical to prevent foam
and moisture from entering the vacuum stack and,
therefore, the vacuum motors.
Twist off the ball assembly from the stand pipe, and clean
the screen. It may be rinsed with water. This screen should
be cleaned frequently if the TruckForce is being operated in
an environment which has an abnormal buildup of lint and
debris, such as cleaning newly installed carpet. Loss of vac-
uum is most normally associated with lint and hair buildup in
the waste filter bag and the float ball shutoff assemble at the
top of the vacuum stand pipe.
AUTO PUMP-OUT
The Automatic Pump-Out system is capable of handling
most debris that passes through the waste filter bag. How-
ever, for optimum performance, keep the waste tank clean
and remove debris from the filter screen of the pump-out.
This should be done on a daily basis, or as needed, depending
upon use, and amount of debris.
Every two weeks, run the pump-out with a full tank of
clean water, to insure that debris and lint are not accumulat-
ing in the base of the pump.
To service the pump-out more thoroughly, unhook the vac-
uum cuff, cut the zip tie around the looped electrical cord,
and lift it out of the waste tank. Unsnap the screen from the
bottom, clean the screen, and clean out the area inside.
If necessary, remove the six screws holding the base to the
motor housing, and clean the base. If the impeller is removed
make sure that a spacing of .050” with shaft pushed toward
housing is maintained when reassembled.
WAND JETS
Remove jets and visually check for wear and debris. Water
or compressed air is best for cleaning—NEVER use a metal
object to remove debris, as it may damage the jet orifice. If
excessive wear is apparent, the jet should be replaced. If the
wand is equipped with jet screens, those should be cleaned by
rinsing with water. Hook up the wand to machine, and check
jet alignment.
FLUSH SOLUTION SYSTEM
At least once a month, the TruckForce, hoses, and tools
should be flushed to remove alkaline residues. Follow the
steps on page 8 of the “Recommended Procedure for Stor-
age,” using a solution of one part warm water with three
parts white vinegar, in place of the antifreeze solution. Then,
repeat the steps using two gallons of fresh water.
WD-40 VAC MOTORS
Should moisture ever enter the vacuum motors, completely
drain the waste tank, open the waste tank lid, remove the vac
shut off ball assembly, turn on all vacuum motors, and spray
a five second burst of WD-40 into the standpipe. Continue to
run the vacuum motors for at least three minutes.
To prevent moisture from damaging the vacuum motors dur-
ing storage, empty the waste tank and store with the lid open.
