SERVICING THE BATTERY

Use the following procedure when removing, installing and 
attaching the battery cables.  

The battery is located in the support foot of the power pack.  
To access the battery you will need another person helping 
you.  

Step 1

Remove the two M8 bolts using a 10 mm wrench.  Keep the 
two bolts nearby for Step 3

WARNING

- Connecting and disconnecting a battery can cause 
sparks and short circuits.  Do not short battery ter-
minals by allowing a wrench or any other object to 
contact both terminals at the same time. 
- A spark or fl ame can cause a lead acid battery to 
explode.
- Before connecting a battery, remove metal 
bracelets, wristwatch bands, rings, etc.  Use gloves 
and protective glasses or face shield when working 
with a battery.

pivoted downward.  This will give you full access to the battery 
and cables.

two M8 screws removed in Step 1 into the exposed holes in 
the battery box (see illustration).  Use one bolt on each side.
