How to Use Battery Jumper Cables
CAUTION
!
If the fork lift truck is out of service for more than 1 month,
the (-) cable of battery should be disconnected.
Otherwise, the starting of engine will be impossible due to
discharge of battery.
If your lift truck battery is discharged (“dead”), you can start your lift
truck by “jumping” it from another lift truck that has a 12-volt,
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.
CAUTION
!
USE ONLY A 12-VOLT, NEGATIVE GROUND SYSTEM to
jump your truck. You can injure yourself and permanently
damage your truck’s 12-volt starting motor and ignition
system by connecting it to a 24-volt power supply (two 12-
volt batteries in series or a 24-volt generating set) or to a
positive-ground system.
WARNING
!
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.
1. 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.
