TO CHARGE THE BATTERIES 
When servicing machine, avoid contact with 
battery acid. 
Batteries emit hydrogen gas. Explosion or fire 
can result. Keep sparks and open flame away. 
Keep covers open when charging. 
Wear eye protection and protective clothing 
when working with batteries. 
Charge batteries in a well ventilated area. Leave 
the solution tank open. 
Use a 24 volt, 20 amp maximum output, DC charger 
which will automatically shut off when the batteries 
are fully charged to charge the two battery pack. 
1.  Stop the machine in a clean, well ventilated area 
next to the charger. 
2.  Turn the machine power off. 
FOR SAFETY: Before leaving or servicing 
machine; stop on level surface, turn off machine 
and remove key. 
3.  Drain solution tank and raise the solution tank 
and lock the support arm. Make sure the 
support arm is fully engaged. 
Batteries emit hydrogen gas. Explosion or fire 
can result. Keep sparks and open flame away. 
Keep covers open when charging. 
4.  Check the electrolyte level in each battery cell. 
Before charging, add just enough distilled water 
to cover the plates. After charging is complete, 
add just enough distilled water to bring up the 
level to the indicator ring. If the water level is 
too high before charging, normal expansion rate 
of the electrolyte may cause an overflow. 
Resulting in a loss of battery acid balance and 
damage the machine. 
5.  Replace the battery caps, and leave them in 
place while charging. 
6.  Unplug the battery connector from the machine. 
FOR SAFETY: When charging, connect the 
charger to the batteries before connecting the 
charger to the AC wall outlet. Never connect the 
charger to the AC wall outlet first. Hazardous 
sparks may result. 
7.  Plug the charger connector into the battery 
connector. Connect the charger AC plug to a 
wall outlet. The charger gauge should indicate 
that the batteries are charging. 
8.  When the batteries are fully charged, disconnect 
the charger from the AC wall outlet, then 
disconnect the charger from the batteries. 
9.  Connect the batteries to the machine connector. 
10. Check the electrolyte level. It should be up to 
the indicator ring. If necessary, add distilled 
water. 
11. Lower the solution tank. 
CHANGING BATTERIES 
Stop the machine in a clean area next to the 
charger. Turn off machine. 
FOR SAFETY: Before leaving or servicing the 
machine; stop on level surface, turn off machine 
and remove key. 
1.  Raise the solution tank. 
2.  Engage solution tank support arm. 
3.  Disconnect battery pack from machine. 
4.  Use the proper size open end wrench to 
disconnect main ground wire first and secure 
cable terminal away from batteries. 
5.  Disconnect main positive lead and secure cable 
terminals away from batteries. 
6.  Loosen both terminals on jumper cable and 
remove. 
7.  Prepare a suitable site to place the batteries. 
8. 
Attach suitable battery lifting device and lift 
batteries from the machine. 
Batteries are a potential environmental hazard. 
Consult your battery supplier for safe disposal 
methods.
