Starting with Jump Start Cables
SMCS Code: 1000; 7000
Batteries give off flammable fumes that can
explode resulting in personal injury.
Prevent sparks near the batteries. They could
cause vapors to explode. Do not allow the jump
start cable ends to contact each other or the
machine.
Do not smoke when checking battery electrolyte
levels.
Electrolyte is an acid and can cause personal
injury if it contacts skin or eyes.
Always wear eye protection when starting a
machine with jump start cables.
Improper jump start procedures can cause an
explosion resulting in personal injury.
Always connect the battery positive (+) to battery
positive (+) and the battery negative (-) to battery
negative (-).
Jump start only with an energy source with the
same voltage as the stalled machine.
Turn off all lights and accessories on the stalled
machine. Otherwise, they will operate when the
energy source is connected.
NOTICE
When starting from another machine, make sure
that the machines do not touch. This could prevent
damage to engine bearings and electrical circuits.
Turn on (close) the battery connect switch prior to
the boost connection to prevent damage to
electrical components on the stalled machine.
Severely discharged maintenance free batteries do
not fully recharge from the alternator after jump
starting. The batteries must be charged to proper
voltage with a battery charger. Many batteries
thought to be unusable are still rechargeable.
This machine has a 24 volt starting system. Use
only the same voltage for jump starting. Use of a
higher voltage damages the electrical system.
Refer to
Special Instruction, Battery Test
Procedure,
SEHS7633,
available
from
your
Caterpillar dealer, for complete testing and
charging information.
Use of Jump Start Cables
When the auxiliary starting receptacles are not
available, use the following procedure:
1. Determine the reason that the engine will not crank.
Refer to Special Instruction, SEHS7768 on the use
of 6V-2150 Starting Charging Analyzer Group. The
procedure is applicable even if the machine does
not have a diagnostic connector.
2. On the stalled machine, place the transmission
direction control in the NEUTRAL position. Engage
the parking brake. Lower all attachments to the
ground. Move all controls to the HOLD position.
3. Turn the engine start switch to OFF on the stalled
machine. Turn off all accessories.
4. Turn on the battery disconnect switch on a stalled
machine.
5. Move the boost machine so that the cables can
reach the stalled machine. DO NOT ALLOW THE
MACHINES TO CONTACT EACH OTHER.
6. Stop the engine on the boost machine. If you are
using an auxiliary power source, turn off the
charging system.
