CONTROL FUNCTIONS
There are control triggers located on each side of the handle under the rubber hand grips.
As you operate the PowerHead, the trigger on your right-hand side controls the electric
motor that drives the cleaning heads. The Safety switch located on the top of the handle
must be depressed while the trigger is pulled. Once the motor is running, the safety switch
can be released. This must be done each time the trigger is released and the motor is
restarted. This lockout will prevent accidental starting of the motor. On the left hand side,
the trigger controls the low pressure carbonating solution spray. The air flows constantly
while the PowerHead is in operation.
MANEUVERING THE POWERHEAD
Your PowerHead maneuvers like a buffer (see Figure 4-2).
1. To move the PowerHead to the right, lift the handle slightly. The more you lift or
lower the handle, the faster the PowerHead will move.
2. To move forward and backward, position the handle so that the unit remains stationary,
then push forward or pull back. To familiarize yourself with your PowerHead, practice
on an open carpeted area. Depress both the solution trigger and motor trigger and
move the PowerHead slowly in a 3 – 5 ft arc, as shown in Section 5 of this manual.
Do not operate your PowerHead on dry carpets. The friction generated by the
revolving cleaning heads may damage fibers in the carpet.
