3. HOW TO USE BATTERY JUMPER CABLES
If your lift truck battery is discharged (dead), you can start your lift truck by jumping it from another lift
truck that has a 24V negative-ground electrical system. The "Booster" battery must be fully charged
and in good condition. This section explains how to perform this procedure safely. To avoid damage
to your lift truck and your battery or the possibility of harm to yourself, follow the instructions and
warnings carefully. If you have any doubts, ask for help from an experienced mechanic.
If your truck has a battery with terminals on the side you will need a set of jumper cables with
matching connector clamps or cable adapters for side mounted battery terminals.
Use only a 24V NEGATIVE GROUND SYSTEM to jump your truck. You can injure yourself
and permanetaly damage your truck's 24V starting motor and ignition system by connecting it
to a 24V power supply or to a positive ground system.
BATTERIES CONTAIN SULFURIC ACID. Avoid acid contact with skin, eyes, or clothing. If
acid contacts your eyes or skin, flush immediately with water and get medical assistance.
Wear safety glasses when working near the battery to protect against possible splashing of
the acid solution.
If the discharged battery has filler caps, check the fluid level. Do not use an open flame to check
and do not smoke. If low, add distilled water to the correct level. Be sure to install the caps before
jump starting.
Do not jump start, charge, or test a sealed type battery if the test indicator looks illuminated or has
a bright color. Install a new battery.
BATTERIES EMIT EXPLOSIVE GAS. Do not smoke or have open flames or sparks in
battery charging areas or near batteries. An explosion can result and cause injury or death.
Hydrogen gas is produced during normal battery operation.
Hydrogen can explode if flames, sparks, or lighted tobacco are brought near the battery.
When charging or using a battery in an enclosed space, always provide ventilation and shield
your eyes. Wear safety glasses when working around batteries.
Put the truck with the booster battery as near to the other truck as necessary for the jumper cables
to reach both batteries. Check and make sure that the trucks do not touch each other. Use
particular care when connecting a booster battery to prevent sparks.
On both trucks:
Put the parking brake switch in the LOCK position.
Put the gear selector lever in the NEUTRAL position.
Turn the start switch to the OFF position.
Turn all accessories to the OFF position and leave them off until after the engine has been
started and the jumper cables have been removed.
To avoid short circuits, remove all jewelry and do not permit any metal tools to make contact
between the positive battery terminal and other metal on the truck. When you connect
jumper cable clamps to the positive terminals of the two batteries, make sure that neither
clamp contacts any other metal. Injury can occur from electrical shock or explosion.
