Charging the Battery
WARNING
Charging the battery produces gasses that
can explode.
Never smoke near the battery and keep sparks
and flames away from battery.
Important:
Always keep the battery fully charged
(1.265 specific gravity). This is especially
important to prevent battery damage when the
temperature is below 0°C (32°F).
1.
Make sure that the filler caps are installed in
battery. Charge battery for 10 to 15 minutes at
25 to 30 A or 30 minutes at 10 A.
2.
When the battery is fully charged, unplug
the charger from the electrical outlet, then
disconnect the charger leads from the battery
posts
(Figure
47).
3.
Install the battery in the machine and connect
the battery cables.
Note:
Do not run the machine with the battery
disconnected, electrical damage may occur.

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.
