BATTERY CHARGING
WARNING!
Hydrogen gas formed during battery charging can explode when
exposed to a spark or flame. Severe injury and property damage
can result. Charge batteries in a well-ventilated area. Keep
battery compartment open during battery charging. Unplug
charger from wall before unplugging machine. Replace dam-
aged charger power cords immediately.
WARNING!
FOR SAFE OPERATION, READ AND UNDERSTAND THE
CHARGER OWNER’S MANUAL.
CAUTION!
The machine’s master switch should be in the ‘OFF’ position
before and during recharging.
Lift open recovery tank for proper ventilation. The machine’s charger plug is
located above the battery compartment, behind the recovery tank. Firmly
connect the charger’s mating plug into the charger plug of the machine. Leave
the tank open to allow ventilation to the battery compartment during charging
operation.
TRANSPORTING
Tie down slots are located on each side of the frame. When transporting,
always strap the machine to the bed of the vehicle.
MAINTENANCE
WARNING!
BEFORE ANY SERVICING, AVOID POSSIBLE INJURY OR
ELECTRIC SHOCK BY HAVING THE MACHINE TURNED OFF
AND THE BATTERY CHARGER DISCONNECTED.
BATTERY CARE
1
Keep water level in cells above the plates. Check daily - if cells need
water, use only distilled or approved water.
2
Keep batteries fully charged when not in use.
3
Keep batteries and terminals clean. When necessary, clean the
terminals with a baking soda solution, then coat them with grease to
retard corrosion.
BATTERY ACID DRAIN (FIGURE 12)
The clear drain hose located at the rear of the machine, will remove excess
liquids from the battery compartment.
CAUTION!
Battery acid is a hazardous material, dispose of properly.
LINT SCREEN (FIGURE 13)
The lint screen is visible through the clear lid on the recovery tank. Keeping this
screen clean insures top performance of the vacuum motor.
SOLUTION FILTER (FIGURE 14)
CAUTION!
Clean solution tank must be empty before removing solution
filter lid, or solution will drain out.
The solution filter is located at the rear of the machine, just behind the water
valve. Regular cleaning will insure proper solution flow. Simply unscrew and
remove the clear lid and screen, clean and reinstall.
DRIVE MOTOR CHAIN TENSION (FIGURE 15)
Traction Drive machines only.
Loosen the jam nut. Turn the screw clockwise to tighten the chain, counter-
clockwise to loosen. When properly adjusted, there should be 1/2” (1.3 cm) of
slack.
CAUTION!
Do not over-tighten. Excessive chain tension can cause dam-
age to the bearings, sprockets, or chain.
