Do These Procedures When You End Your Work

NOTE: Always engage the parking brake (if equipped)

before servicing the machine.

1. Drain the solution tank (Figure 3 ) and the recovery

tank (Figure 4). To drain the tanks , follow this

procedure:

a. Turn the key switch “OFF”.

b. Remove the drain hose from the back of the

machine.

c. Put the end of the hose over a drain or bucket.

d. Turn the valve handle to the left. Pull the handle

out to open the drain. (Figure 5)

NOTE: Have the opening in the side of the valve away

from you when you open the valve.

e. To open the valve completely, turn the handle

to the right. Pull the handle out of valve. (Figure

2. Flush the tanks. To flush the tanks, put clean water in

the tank through the opening on top of the tank.

CAUTION: Make sure water or solution does

not enter the opening for the

vacuum motor. See figure 2.

3. If a tank or drain hose has an obstruction, use a high

pressure water hose to flush the tank or hose. Put the

water hose into the drain hose.

4. Leave the tanks and the drain valves open to dry in the

air.

5. Check the squeegee blade. Use a cloth to clean the

squeegee blade. If the squeegee blade is damaged or

worn, turn or replace the blade.

6. Check and clean the solution lid gasket. Use a mild

cleaning solution and rinse the parts in clean water.

Check the batteries and add distilled water as needed. The

correct level is within 1/4 inch of the bottom of the tube in

each cell.

CAUTION:Tap water may contain contami-

nants that will damage batteries.

Batteries must be refilled with

distilled water only.

WARNING: Lead acid batteries generate

gases which can cause an explo-

sion. NO SMOKING. Always wear

eye protection and protective

clothing when working near

batteries.

Use a clean cloth and wipe the surface of the machine.

These Maintenance Procedures Must Be Done Every

Week:

WARNING: Maintenance and repairs must be

done by authorized personnel only.

Always empty the solution tank and

the recovery tank before doing any

maintenance. Keep all fasteners

tight.

WARNING: Always wear eye protection and pro-

tective clothing when working near

batteries. Do not put tools or other

metal objects across the battery ter-

minals or the tops of the batteries.

CAUTION: To prevent damage to the machine,

and discharge across the tops of the

batteries, do not fill the batteries

above the bottom of the tube in each

cell. Wipe any acid from the ma-

chine or the tops of the batteries. Do

not add acid to battery after installa-

tion.

WARNING: Always wear eye protection and pro-

tective clothing when working near

batteries. NO SMOKING!

1. To inspect batteries, tip up recovery tank and latch the

stop to hold the tank up. See Figure 7.

2. Disconnect the batteries. Use a cloth and a solution

of ammonia or bicarbonate of soda to wipe the top of the

batteries. Clean the battery terminals. Reconnect the

batteries.

3. Check the hoses for leaks, obstructions and other

damages.

4. Check and clean the filter screen in the solution hose.

To clean the screen, follow this procedure: (See figures

13 and 14 page 24)

a. Turn the connector to the left.

b. Remove and clean the filter screen.

c. Install the filter screen in the hose. Turn the

connector to the right to connect the hose.

5. Use a grease gun to lubricate the caster. See figure

6. Check the squeegee and the scrub brush or the pad

driver for damage.

7. Check the squeegee and the vacuum hose for damage,

leaks and obstructions.

Maintenance For The Squeegee

To remove the squeegee, follow this procedure:

1. Remove the squeegee assembly by loosening the two

knobs that attach the squeegee to the machine. Pull

the squeegee assembly off. See figure 9.

2. Inspect the squeegee blade.

3. If the blade is worn, turn the blade so that a new edge

is in the wiping position.

4. Reinstall squeegee assembly on the machine.

How To Adjust The Squeegee

The following adjustments are set at the factory, however

they may require slight adjustment.

Adjusting Squeegee Pressure:

To adjust the pressure, refer to Figure 10. Proper

adjustment will produce a uniform flare along the rear

blade when the machine is moved forward. To increase

pressure, loosen bolt and slide squeegee mount down.

To decrease the pressure, loosen the bolt and slide

squeegee mount up.

Adjusting Squeegee Tilt:

The tilt of the squeegee causes the rear blade to raise up

in the center or on the ends, depending on which

direction the tilt is changed. For tilt adjustment, refer to

figure 11. Loosen left and right screw "X". In order to

bring the rear blade down in the center, tip "Y" down. To

bring both ends down, tip "Y" up. Make very small

adjustments and try it until a uniform flare is achieved.

Changing the tilt may also require readjusting the squee-

gee pressure.

Adjusting Squeegee Swing:

The factory sets the squeegee swing for using the 33"

squeegee. If you are using the optional 29" squeegee, the

stop screws (page 35, ref. # 20) must be adjusted in. This

is done by loosening the jam nut (page 35, ref. #10); turning

the screw in; and then retightening the nut. The squeegee

(29" or 33") is properly adjusted when it will swing all the

way left or right to within 3/4" of the drive wheels without

hitting them.

Adjusting Squeegee Blades:

When properly installed the front blade should be ap-

proximately .06 above the rear blade. See figure 12.

Adjusting Squeegee Support Wheels:

The support wheels should be set at .12 above the floor

with the rear blade touching the floor. See figure 12.

3. Remove brushes/pads.

4. Locate the solution shut-off valve. It is located behind

the left wheel.

5. Turn solution valve "OFF". See figure 14 (A).

6. Locate the solution filter screen. It is located on the

back of the solution valve. See figure 14 (B).

7. Unscrew the female garden hose connector from the

back of the solution valve. The filter screen is in the

female connector.
