ASSEMBLY INSTRUCTIONS
Remove all cord wraps and uncoil the cables prior to using the battery charger.
This battery charger is for use on a nominal 230 volt circuit.
USING AN EXTENSION CORD
Make sure your extension cord is in good condition. When using an extension cord, be
sure to use one heavy enough to carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of power and overheating.

Preparing to Charge
1. Determine voltage of battery to be maintained by referring to the vehicle manual.
2. If it is necessary to remove battery from vehicle to charge, or to clean terminal, always
remove grounded terminal from battery first. Make sure all accessories in the vehicle
are off, so as not to cause an arc.
3. Clean battery terminals. Do not allow corrosion to come in contact with eyes.
4. Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery
without cell caps (maintenance free), carefully follow manufacturer’s charging
instructions.
