How To Prepare the Machine For Operation  
Battery Maintenance  
The electrical power to operate the machine comes from the storage bat-  
teries. Storage batteries need preventative maintenance.  
Correct Fill  
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 electrolyte  
each time you charge the batteries (see figure 4).  
Figure 4  
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 batteries. 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 bicarbonate of  
soda to get into the batteries.  
3. Keep the batteries charged.

(see figure 5, A - Red, B - Yellow, C - Green ). For color indications  
see figure 6.  
Recharging the Batteries  
The Scrubtec R comes with an on board charger.  
1. Plug into any wall socket and charging is automatic.  
2. Observe indicator light to ensure the charging process has started  
(see figure 5, A - Red, B - Yellow, C - Green ). For color indications  
see figure 6.  
NOTE: Make sure you plug into a circuit that is not loaded by other equip-  
ment. Wall breakers may be tripped and no charge will occur.  
WARNING: Never charge a GEL battery with an unsuitable battery  
charger. Carefully follow the instructions given by the  
manufacturer of the batteries and battery charger.  
NOTE: To prevent permanent damage to the batteries, avoid their complete  
discharge. Never leave the batteries completely discharged, even if the  
machine is not being used. When recharging the batteries, keep the base  
support of the seat lifted. After every 20 recharging operations, check the  
level of the electrolyte and if necessary top off with distilled water.
