MAINTENANCE
DAILY MAINTENANCE:
1. Remove the 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 Vacuum Shut-Off
screen and Drain Saver Basket located inside the
Recovery Tank.
3. Drain and rinse Recovery Tank thoroughly.
4. Inspect Vacuum Hose for any objects obstructing the
air fl ow.
5. Raise Squeegee and wipe Blades with a clean cloth.
Store Squeegee in the raise position to prevent
damage or setting of the Blades.
6. Wipe down machine if needed. Use a non-abrasive,
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 fi ll as needed. Always use distilled water to refi ll
Batteries. Batteries should be fi lled approximately
3
⁄
4
'' to 1'' above the plates. Overfi lling 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. Flip Scrubdeck Brushes / Pads.
4. Drain and rinse tanks thoroughly. To thoroughly fl ush
out any solution chemicals in solution line valves, refi ll
solution tank with a few gallons of warm, clean water
and run the machine until tank is empty.
5. Remove and Clean Solution Filter Screen.
MONTHLY MAINTENANCE:
1. Check Scrubdeck 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:
OEM Trojan WET Batteries
- 100 in/lbs
OEM Full River AGM Batteries
- 90in/lbs
4. Grease Squeegee Pivot Point.
YEARLY MAINTENANCE:
Call your local dealer for yearly maintenance.
STORING MACHINE:
1. Be sure to fl ush the Tanks out completely. To
thoroughly fl ush out any solution chemicals in solution
line and valves, refi ll 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 Scrubdeck and Squeegee.
CHECKING BATTERY SPECIFIC GRAVITY:
Use a hydrometer to check the Battery specifi c gravity.
Checking Gravity:
• Hydrometer
• Battery
NOTICE
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

NOTICE
If the readings are taken when the battery electrolyte
is any temperature other than 80
°
F(27

C), the reading
must be temperature corrected. To fi nd the corrected
specifi c gravity reading when the temperature of the
battery electrolyte is other than 80
°

the specifi c gravity reading 0.004 (4 points), for each
10
