OPERATING PROCEDURES
OPERATION (continued)
10. As dirty solution is recovered, some foaming may be noted. Excessive foaming can be counteracted with liquid
defoamer applied according to the chemical manufacturers directions. DO NOT ALLOW FOAM TO RISE INTO OR NEAR
THE DOME; THIS WILL HARM THE VACUUM MOTOR. Use defoamer or empty and flush the recovery tank.
11. To empty the recovery tank, remove the dome assembly and lift the tank out. Dispose of the recovered water properly.
12. If streaking occurs after a period of operating time, this means the solution (fresh water) tank is near empty. Streaking
is eliminated by adding more water and chemical solution to the tank. EMPTY THE RECOVERY TANK EVERY TIME YOU
FILL THE SOLUTION TANK.
13. To empty the solution tank, connect the power fill adaptor to the vacuum inlet on the front of the dome. Turn the
vacuum switch on.
OPERATING WITH ACCESSORY TOOLS
1. To use an accessory tool, disconnect the supply hose at the rear of the machine and connect the accessory tool hose.
2. Next, disconnect the machine’s vacuum hose from the front of th edome assembly and connect the accessory tool
vacuum hose to the dome.
3. Turn the vacuum and accessory pump switches on. Solution will be dispensed while the accessory tool trigger is
depressed.
WATCH THE DOME TO MAKE SURE THE RECOVERY TANK DOES NOT OVERFLOW.
Note: The pump motor is equipped with an automatic thermal protection device. If the motor overheats for any reason,
the thermal protector will activate and automatically turn the motor off. If this occurs the operator should turn the manual
pump switch to the off position and allow approximately fifteen minutes for the motor to cool. When the motor has cooled
to a safe operating termperature, the thermal protector will automatically close and allow power to be supplied to the
motor via the manual pump switch. The operator will be able to resume normal operation. If the pump motor shuts down
repeatedly, it should be checked at an Authorized Service Center.
SERVICING
This self-contained extractor is designed and manufactured to provide years of trouble free service with a minimum of
maintenance and service. The following recommendations are intended to assist the operator and Service Technician in
performing routine maintenance.
WARNING: Always unplug your machine before performing any service. Severe personal injury could result if the
electrical power is not disconnected.
After each use:
1. Clean the dome top, intake filter screen, gasket and recovery tank with fresh, clean water. Do not reinstall the dome
until the next use, this will allow the recovery tank to dry out.
2. Flush the solution tank and inlet screen with clean water. Vacuum all water out using the Power Fill adapter.
3. Remove any debris on the scrub brush, vacuum head and around the spray jets.
4. Make sure the brush assembly lift lever is locked in the rasied position.
5. Store your machine in a dry, protected area.
Do not expose this machine to rain, standing water or freezing
temperatures.
Periodically:
After continuous or repeated use the jets and check valves will need cleaning. Unplug the cord and empty the recovery
and solution tanks. Tilt the machine backwared. Remove the jet caps, jets and check valves shown in the brush assembly
illustration and soak in white vinegar until visible deposits are dissolved, then scrub with a soft bristle brush.
Note: Jets and
check valves should be replaced once a year,
because they tend to erode under extended use. This may cause overuse of
solution and streaking.
An Authorized Service Center should perform the following procedures:
The cogged belt drive system rarely requires tightening. If the belt becomes loose from wear, it is time to replace it. To do
so, remove acorn nut and thru-bolt from brush chassis lift handle. Gently tilt machine backwards. While holding the base of
the brush housing with one hand, release the lift handle from the up/locked position. The brush housing privots on a hinge
thta doesn’t need to be removed. Loosen the two motor bracket mounting bolts with a 7/16” wrench. DO NOT REMOVE
THE BOLTS UNLESS YOU ARE REPLACING THE MOTOR. Slide the motor away from the brush to tighten the belt or toward
the brush to remove. If you are replacing the belt it will be necessary to remove the brush assembly to install a new one.
