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 ﬂ oat shut-off screen

and Drain Saver located inside the Recovery Tank.

3. Drain and rinse Tanks thoroughly and ﬂ ush out

Solution Feed to deck.

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

⁄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.

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, 8-10 ft/lb MAX.

4. Grease caster swivel and 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 pad 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

SPECIFIC GRAVITY

@ 80°F (27°C)

CONDITION

1.265 100% Charged

1.225 75% Charged

1.190 50% Charged

1.155 25% Charged

1.120 Discharged

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°F(27°C): add (+) to

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

10°F(6°C) above 80°F(27°C). Subtract (-) from the

speciﬁ c reading 0.004 (4 points), for each 10°F(6°C)

below 80°F(27°C).
