BATTERY MAINTENANCE
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and
open flame away. Keep battery compartment open
when charging.
FOR SAFETY: When servicing machine, wear
protective gloves when handling batteries and
battery cables. Avoid contact with battery acid.
1.
Always follow proper charging instructions (See
Battery Charging).
2.
After charging, check fluid level (A). Fluid level
should be within 3 mm (0.13 in) of full level
indicator. Add distilled water if needed. DO NOT
OVERFILL. Overfilled batteries can overflow
during charging due to fluid expansion
(Figure 24).

3.
Keep battery tops and terminals clean and dry.
To clean batteries:
a.
Mix a strong solution of baking soda and water
(Figure 25).
FIG. 25
b. Brush solution sparingly over battery tops,
terminal and cable connectors.
NOTE: Do not allow baking soda solution to enter
battery cells.
c.
Use wire brush to clean terminal post and
cable connections.
d.
After cleaning, apply a coating of clear battery
post protectant to terminals and cable
connections.
4.
Check for loose or worn cables. Replace if worn.
ADJUSTING BRUSH HEIGHT
Brush height is factory preset and should not require
any adjustment. If brush height adjustment is
necessary, follow steps below.
Proper brush height is correct when bristles slightly
bend creating a flicking action on the carpet.
To adjust brush height:
1.
Stop machine on level surface and pull out main
circuit breaker button to shut-off power. Button is
located at rear of control console.
2.
Carefully hinge open recovery tank to access
brush height adjustment screws.
3.
Loosen the two brush height lock screws as
shown. Do not remove screws (Figure 26).
FIG. 26
4.
Then turn the two adjustment screws an equal
amount of turns as shown (clockwise to raise). It is
very important that screws are turned an equal
amount, otherwise the brush will tilt causing
premature brush wear and ineffective cleaning
(Figure 27).
