Yearly Maintenance
1. Call your local dealer for yearly maintenance
Storing Machine
1. Be sure to flush the tanks out completely. To thoroughly
flush out any solution chemicals in solution line and valves,
refill solution tank with a few gallons of warm clean water
and run machine until tank is empty.
2. Open the recovery tank lid to promote air circulation.
3. Raise brushes and squeegee.
Checking Battery Specific Gravity
Use a hydrometer to check the battery specific gravity.
Checking Gravity
A. Hydrometer
B. Battery
Note: do not take readings immediately after adding
distilled water, if water and acid are not thoroughly mixed,
the reading may not be accurate.
Check the hydrometer against this chart
Daily Maintenance
1. Remove and clean pads or brushes. Never use soiled
pads when cleaning. Replace pads when they become
packed with residue.
2. Remove and clean debris from the float shut-off screen
and drain saver located inside the recovery tank.
3. Drain and rinse tanks thoroughly
4. Inspect vacuum hose for any objects obstructing the
air flow.
5. Raise squeegee and wipe blades with a clean cloth.
Store squeegee in the raised position to prevent damage
or setting of the blades.
6. Wipe down machine if needed. Use a nonabrasive,
non solvent cleaner, or a clean damp cloth.
7. Recharge the batteries if needed.
Weekly Maintenance
1. Check battery water level in each cell of the batteries,
and fill as needed. Always use distilled water to refill
batteries. Batteries should be filled approximately 3/4" to 1"
above the plates. Overfilling will cause the batteries to
leak during charging. The charging process creates gas
bubbles inside the battery, which effectively increases the
volume of the electrolyte.
2. Clean battery tops to prevent corrosion.
3. Rotate brushes. Rotate the left to the right and right to
left. On cylindrical models from front to back, or end to
end if using different materials.
4. Drain and rinse tanks thoroughly. To thoroughly flush
out any solution chemicals in solution line and valves, refill
solution tank with a few gallons of warm clean water and
run machine until tank is empty.
Monthly Maintenance
1. Check scrub head and squeegee lifting cables for
wear and spring tension.
2. Check machine for water leaks and loose nuts and
bolts.
3. Check to see if battery cables are tightened
(Tighten if needed)
4. Check parking brake
