Store the machine in a clean, dry place.
CHARGING THE BATTERIES
Charge the batteries when the Battery Condition Indicator (19) is flashing RED.
CAUTION!
Do not allow the batteries to sit in a discharged condition. Doing
so will greatly reduce battery life.
WARNING!
Do not fill the batteries with water before charging.
Charge batteries in a well-ventilated area.
Do not smoke while servicing the batteries.
Disconnect the batteries. Push the connector from the charger into the Battery
Connector / Charger Plug (17) on the batteries. Follow the instructions on the
battery charger.
CAUTION!
To avoid damage to floor surfaces, wipe water and acid from the
top of the batteries after charging.
CHECKING THE BATTERY WATER LEVEL
Check the water level of the batteries at least once a week.
After charging the batteries, remove the vent caps and check the water level
in each battery cell. Use distilled water in a battery filling dispenser (available
at most auto parts stores) to fill each cell to the level indicator (or to 10 mm (3/
8”) over the top of the separators). DO NOT over-fill the batteries!
CAUTION!
Acid can spill onto the floor if the batteries are overfilled.
Tighten the vent caps. Wash the tops of the batteries with a solution of baking
soda and water (2 tablespoons of baking soda to 1 liter / 1 quart of water).
LUBRICATING THE MACHINE
Once a month, apply oil to lubricate the:
•
Front Swivel Casters
•
Squeegee Pivot Points
•
Brush Lift Linkage
•
Rear Wheel Bearings
•
Solution Valve Linkage
•
Kick Stand
VACUUM MOTOR BRUSHES
Have Nilfisk check the carbon motor brushes once a year or after 300
operating hours.
IMPORTANT !
Motor damage from failure to service the carbon brushes is not
covered under warranty.
C - SQUEEGEE CARTRIDGE ROTATION OR REPLACE-
MENT
If the squeegee leaves narrow streaks of water, it is probably dirty or
damaged. Remove the squeegee, rinse it under warm water and inspect the
squeegee blades. Rotate the squeegee cartridge if the rear blade is cut, torn,
or worn to a radius. Replace the squeegee cartridge if both blades are cut,
torn, or worn to a radius.
To Rotate the Squeegee Cartridge...
1
Raise the Squeegee Assembly (8).
2
Remove the Squeegee Assembly (8) from the machine.
3
Remove the squeegee cartridge from the Squeegee and rotate it as
shown (or replace if both blades are severely worn or torn).
4
Reinstall the cartridge into the Squeegee Assembly (8) and the
Squeegee Assembly (8) onto the machine.
NOTE: The Squeegee Assembly (8) is not adjustable.
