MAINTENANCE TO BE DONE EVERY WEEK
WARNING:
WARNING:
CAUTION:
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.
Always wear eye protection and protective clothing when working near batteries. NO SMOKING! Do not put tools or other metal objects across the battery terminals or the tops of the batteries.
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 machine or the tops of the batteries. Do not add acid to batteries after installation.
Battery Inspection and Cleaning
1. Turn the key switch to the “OFF” position and set the parking brake.
2. To inspect batteries, rotate seat support forward and lean it against the steering wheel. Lift and rotate recovery tank to the rear until it latches in the open position. Be sure the recovery tank is empty before lifting.
3. 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. See the instructions in the section of this book called “Battery Maintenance”.
4. When battery inspection is completed, unlatch and close the recovery tank. Rotate the seat support back to the operating position.

Cleaning the Recovery Tank and Filter
1. Turn the key switch to the “OFF” position and set the parking brake.
2. Lift and rotate the seat support forward and rest it against the steering wheel.
3. Empty the recovery tank using the flexible drain hose by unscrewing the knob and taking off the plug (see figure 45).
4. Open the lower cleaning port cover by unscrewing the knob and rotating the clamping bar (see figure 46).
5. Remove the recovery lid, rinse the tank and clean the drain plug.

Maintenance
6. Clean the hose fitting in the recovery tank and spray water down the squeegee hose to clean out debris.
7. Remove the vacuum hose adapter from the top of the recovery tank by rotating it counter-clockwise and pulling it upwards (see figure 47).
8. Remove the filter and the float assembly from the recovery tank.
9. Rotate the filter inside the protection housing counter-clockwise and remove it.
10. Thoroughly clean the filter and all of the component parts with water.
11. Reinstall the filter and the float assembly and replace it in the recovery tank.
12. Reinstall the lower cleaning port cover, making sure that the gasket is in position.
13. Reinstall the drain plug and tighten.
Cleaning the Solution Tank and Filter
1. Move the machine so that the solution tank filter assembly is located directly over a floor drain.
NOTE: The solution tank does not have a drain hose.
It is drained through the filter body located in the front and underneath the machine (see figure 48).
2. Turn the key switch to the “OFF” position and set the parking brake.
3. Close the solution flow valve by sliding it to its up most position (see figure 49).
4. Unscrew the filter housing by turning it counterclockwise (see figure 48). Remove the filter screen from the housing and clean it carefully.
5. With the filter body located above the floor drain, slide the solution flow valve downward to its full open position. The solution tank will immediately start draining.
6. Clean inside the solution tank with a jet stream of water.
7. Close the solution flow valve.
8. Replace the filter inside the housing and reinstall on machine.

Readjust or replace if necessary.
Front Squeegee Blade Replacement
To replace the front squeegee blade, follow this procedure:
1. Remove the squeegee assembly from the machine.
2. Remove mounting screws and front squeegee blade.
3. Install new front squeegee blade and reinstall mounting screws.
4. Replace squeegee on machine.
Rear Squeegee Blade Replacement
If the rear squeegee blade is worn and does not dry the floor well, follow this procedure:
1. Remove the squeegee assembly from the machine.
2. Push and rotate the small tabs on the squeegee so that they will slip through the holes in the squeegee blade clamping plate (see figure 50).
3. Remove the squeegee blade and inspect it.
4. Rotate the squeegee blade to obtain a new cleaning edge. Replace if necessary.
5. Reinstall the squeegee blade.
