Jump-Starting the Machine
1.
Check the weak battery for terminal corrosion
(white, green, or blue “snow”).
You must clean it off 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; otherwise,
damage may occur to the engine.
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
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 battery-terminal polarity and
jumper-cable polarity when connecting
batteries.
Note:
The following instructions are adapted
from the SAE J1494 Rev. Dec. 2001 –
Battery Booster Cables – Surface Vehicle
Recommended Practice (SAE – Society of
Automotive Engineers).
Important:
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 machines do
not touch and that both electrical systems
are shut 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 (

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 machine (not to the negative post)
away from the battery. Stand away from the
machine.
7.
Start the vehicle and remove the cables in the
reverse order of connection (the engine block
(black) connection is the first to disconnect).
