HANDLE ADJUSTMENT
For comfort and convenience, the handle can rotate at a full 180° at approximately 9° increments. Simply by pulling the rotation lever, Figure 1, the handle can
pivot to any comfortable level, Figure 2.
WARNING!
BEFORE ADJUSTING THE BELT, DISCONNECT THE POWER CORD FROM THE ELECTRICAL OUTLET.
BELT ADJUSTMENT
To adjust the belt, start by removing the recovery tank, preferably after emptying its contents, Figure 3. Next, after emptying the solution tank, remove the two
nuts that lock the solution tank to the lower frame. For more information on emptying the solution tank, see "SOLUTION". The two nuts can be located underneath
the edge of the solution tank at the end opposite of its hinge. Once the nuts are removed, you can now lift the solution tank, pivoting it on its hinge, to reveal the
extractor's mechanics, Figure 4. To gain access to the motor mounts, you must remove the lower skirt by removing the two Screws (A) shown in Figure 5.
Once the two screws are removed, remove the vacuum hose and pull the skirt forward spreading the rear sides apart until the skirt becomes free. Now you're ready
to loosen the four motor mount bolts by giving them no more than two or three turns. To keep the desired distance between the pulley and the frame wall, wedge
a Screwdriver (B) between the pulley and the side of the frame wall while you're adjusting the motor mount, Figure 6. Now you're ready to adjust the belt. Turn
the Adjustment Screw (C), located in Figure 6, clockwise to tighten and counterclockwise to loosen.
Once adjusted, tighten the four motor mount screws, remove the wedged screwdriver, and replace the lower skirt by sliding it on while spreading the rear sides
apart until the skirt locks in place. Replace the two screws in the front of the skirt. After replacing the two screws in skirt, you're now ready to lower the solution
tank and lock it in place with the two nuts.
WARNING!
DO NOT FORGET TO LOCK THE SOLUTION TANK DOWN WITH THE ORIGINAL TWO NUTS!
Now you're ready to replace the recovery tank and continue cleaning.
BRUSH PRESSURE ADJUSTMENT
The brush pressure knob, Figure 7, is located on the top of the lower skirt at the same end as the vacuum shoe. To add brush pressure, turn the knob clockwise
as shown on the knob. NOTE: Adding too much pressure may pull out carpet fiber or overload the brush motor. If the brush motor overloads, the circuit breaker,
located on the control panel, will trip. This means you've added too much pressure. To reduce brush pressure, turn the knob counterclockwise also as shown on
the knob.
FEATURES
Your carpet extractor features a Recovery Drain Hose (D), a Solution Drain Valve (E), Figure 8, and a filter located inside the solution tank, Figure 13. Your carpet
extractor is also equipped with an Accessory Inlet (F), Figure 9, for the optional accessories: Carpet Wand, Hand Tool, and Vacuum Hose & Solution Line. To use
an accessory, simply connect the optional solution line into the accessory inlet and connect the optional vacuum hose into the vacuum port of the clear lid. For
information on ordering any of these accessories, refer to "OPTIONAL ACCESSORIES".
VACUUM SWITCH
The vacuum switch, Figure 10, turns the vacuum motor on. The recovery tank will instantly operate under vacuum and the floor nozzle will be ready to pick up
(extract) the dirty solution. For operation, the recovery tank's drain hose must be connected to the hose plug, Figure 11, and the tank's clear lid in position, Figure
12.
PUMP SWITCH
The pump switch, Figure 10, turns the solution pump on. The pump will draw filtered solution, from the solution tank, to the nozzles located beneath the frame.
The nozzles distribute the solution evenly over the carpet. Water temperature in the solution tank must not exceed 130°F.
The Pump Switch is a combo maintained/momentary switch with a light. Pressing the rocker torward the light gives a maintained supply for continuous operation.
Pressing the rocker away from the light is a momentary supply of water. The light is activated in either water supply operation.
BRUSH SWITCH
The brush switch, Figure 10, turns the brush on. The rotation of the brush may propel the carpet extractor, reducing the effort needed for operation. The self propelling
feature may change with different carpets.
CIRCUIT BREAKER
The circuit breaker, Figure 10, will trip when there is an overload on the brush. Once tripped, stop cleaning, reduce brush pressure using the brush pressure knob,
Figure 7, reset the circuit breaker, and begin cleaning again. If circuit breaker consistently trips with little or no brush pressure, unplug the carpet extractor from
the electrical outlet and check the brush roll for possible lodged debris or carpet fiber.
