Jump Starting the Machine

1. Check the weak battery for terminal corrosion
and clean it prior to jump starting. Clean and
tighten connections as necessary.
CAUTION
Corrosion or loose connections can
cause unwanted electrical voltage spikes
at anytime during the jump-starting
procedure.
Do not attempt to jump start with loose
or corroded battery terminals or damage
to the engine may occur.
DANGER
Jump starting a weak battery that is
cracked, frozen, has low electrolyte level,
or an open/shorted battery cell, can
cause an explosion resulting in serious
personal injury.
Do not jump start a weak battery if these
conditions exist.
2. Ensure that the booster is a good and fully
charged lead acid battery at 12.6 V or greater.
Use properly sized jumper cables (4 to 6
AWG) with short lengths to reduce voltage drop
between systems. Ensure that the cables are
color coded or labeled for the correct polarity.
CAUTION
Connecting the jumper cables incorrectly
(wrong polarity) can immediately damage
the electrical system.
Be certain of the battery terminal polarity
and jumper cable polarity when hooking
up the batteries.
WARNING
Batteries contain acid and produce
explosive gases.
• Shield your eyes and face from the
batteries at all times.
• Do not lean over the batteries.
Note:
Ensure that the vent caps are tight and
level. Place a damp cloth, if available, over any
vent caps on both batteries. Ensure that the
vehicles do not touch and that both electrical
systems are off and at the same rated system
voltage. These instructions are for negative
ground systems only.
3. Connect the positive (+) cable to the positive (+)
terminal of the discharged battery that is wired
to the starter or solenoid as shown in
1. Positive (+) cable on discharged battery
2. Positive (+) cable on booster battery
3. Negative (–) cable on the booster battery
4. Negative (–) cable on the engine block
5. Booster battery
6. Discharged battery
7. Engine block
4. Connect the other end of the positive cable to
the positive terminal of the booster battery.
5. Connect the black negative (–) cable to the other
terminal (negative) of the booster battery.
6. Make the final connection on the engine block
of the stalled vehicle (not to the negative post)
away from the battery. Stand back.
7. Start the vehicle and remove the cables in the
reverse order of connection (the engine block
(black) connection is the first to disconnect).
