Battery Maintenance
The electrical power to operate the machine comes
from the storage batteries. Storage batteries need
preventative maintenance.
WARNING: Working with batteries can
be dangerous. Always wear
eye protection and protective
clothing when working near
batteries. NO SMOKING!
To maintain the batteries in good condition, follow
these instructions:
1. Keep the electrolyte at the correct level. The
correct level is between 1/4" (1/2 cm) below the
bottom of the tube in each cell and above the
tops of the plates. Check the level of the electro-
lyte each time you charge the batteries. See
figure 10.
NOTE: Check the level of electrolyte prior to charging
the batteries. Be sure the plates in each cell are
covered with electrolyte before charging. Do not top
off the cells prior to charging the battery. Electrolyte
expands during charging. As a result, the electrolyte
could overflow from the cells. Always top off the cells
with distilled water after charging.
CAUTION: Irreversible damage will occur to
the batteries if electrolyte does
not cover the plates. Keep the
electrolyte at the correct level.
CAUTION: Machine damage and discharge
across the tops of the batteries
can occur if the batteries are over
filled. Do not fill the batteries up
to the bottom of the tube in each
cell. Wipe any acid from the
machine or the tops of the batter-
ies. Never add acid to a battery
after installation.
CAUTION: Batteries must be refilled with
distilled water only. Do not use
tap water as it may contain
contaminants that will damage
batteries.
2. Keep the tops of the batteries clean and dry.
Keep the terminals and connectors clean. To
clean the top of the batteries, use a damp cloth
with a weak solution of ammonia or bicarbonate
of soda solution. To clean the terminals and
connectors, use a terminal and connector
cleaning tool. Do not allow ammonia or bicar-
bonate of soda to get into batteries.

removes the dirty solution from the floor. Use your
hand to lower or raise the squeegee handle. To
operate the squeegee, follow this procedure:
1. To lower the squeegee and start the vacuum
motor, move the squeegee lever to the right and
down. See figure 17.
2. To raise the squeegee, lift the squeegee lever up.
See figure 18.
NOTE: The center position lets the vacuum motor
continue to run with the squeegee off the floor to avoid
drips and also allows you to back up the machine.
How To Fill The Solution Tank
The solution tank can be filled in the front or through
the clear drain hose at the rear of the machine (See
figure 19). To fill the solution tank follow this proce-
dure:
1. Add a cleaning chemical to the solution tank.
For the correct amount of chemical, follow the
directions shown on the container.
2. Fill the solution tank with water. When filling
machine in the front with a hose, position hose
inside the fill screen as shown in figure 19A.
When filling machine from the rear, position clear
drain hose against bracket and insert hose as
shown in figure 20 Solution level can be viewed
