SERVICING
The 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.
Failure to follow these recommendations can result in damage to your machine and diminished performance.
Warning: Always unplug your machine before performing any service. Severe personal injury could result
if the electrical power is not disconnected.
1.
Always follow through with the recommended prestart-up checks found in the Preparation and Transportation
section of this manual.
2.
Store your machine in a dry, protected area with the brush chassis raised and locked in place. Do not expose this
machine to rain, standing water or freezing temperatures.
3.
We recommend a good, thorough cleaning after each use. Clean the dome top, intake filter screen and recovery
tank with fresh, clean water. Flush the fresh water tank and strainer periodically with clean water.
4.
After continuous or repeated use, the jet tips and strainer/check valves will need cleaning. Unplug the cord and
empty the recovery and solution tanks. Tilt the machine backward allowing it to balance on the wheels and drain
valve. Remove the jet caps shown in the brush chassis illustration and clean with white vinegar and a soft bristle
brush. Remove the jet tip and strainer/check valve and soak it in vinegar until visible deposits are dissolved, then
scrub with a soft bristle brush.
Jet tips and strainer/check valves should be replaced once a year because they tend to erode under extended
use. This can cause overuse of solution and possible streaking.
AN AUTHORIZED SERVICE CENTER SHOULD PERFORM THE FOLLOWING PROCEDURES
1.
Drive Belt Adjustment and/or Replacement: The cogged drive belt system rarely needs tightening, so if
it becomes loose from wear, it is time to replace it. Follow this procedure:
a)
Remove the two screws that attach the hanger bracket to the brush shroud. Then remove the thru-bolt from
the brush chassis and lift handle. Remove the lift handle and lift stop.
b)
Tilt the machine backward allowing it to balance on the wheels and drain valve. The brush chassis will remain
on the floor exposing the brush drive belt and motor.
c)
Loosen the two motor bracket mounting 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 for removal.
Unlike a “V” type belt, the cogged belt is run with basically zero deflection. To test the belt tension, hold
the belt between your thumb and forefinger and twist to the side. It should turn approximately 90
°
with little
effort. If it twists more than 90
°
, retighten the belt.
2.
Pump Replacement:
a)
Remove the lift stop handle as described in the “Belt Drive” procedure (#1a).
b)
Tilt the machine backward as described in the “Belt Drive” procedure (#1b)
c)
Disconnect black wire (#2) and the white wire from the bridge rectifier (part #A130172). Also disconnect the
ground wire (this will need to be respliced and reconnected to the ground wire on the brush motor when
reassembling). Reference the electrical schematic.
d)
Remove the two hoses from the pump. It is now fully exposed for replacement.
e)
When reassembling after any repairs, make certain that all wire connections are properly plugged in and
secure.
f)
Make all solution hose connections secure.
