Battery - Replace
Batteries give off combustible gases which can
explode. A spark can cause the combustible gas-
es to ignite. T
his can result in severe personal in-
jury or death.
Ensure prope
r ventilation for batteries that are in
an enclosure. Follow the proper procedures in or-
der to help prevent electrical arcs and/or sparks
near batteri
es. Do not smoke when batteries are
serviced.
The battery cables or the batteries should not be
removed with the battery cover in place. The bat-
tery cover should be removed before any servic-
ing is attempted.
Removing the battery cables or the batteries with
the cover in place may cause a battery explosion
resulting in personal injury.
1. Switch the engine to the OFF position. Remove
all electrical loads.
2. Turn off any battery chargers. Disconnect any
battery chargers.
3. The NEGATIVE “-” cable connects the NEGATIVE
“-” battery terminal to the NEGATIVE “-” terminal
on the starting motor. Disconnect the cable from
the NEGATIVE “-” battery terminal.
4. The POSITIVE “+” cable connects the POSITIVE
“+” battery terminal to the POSITIVE “+” terminal
on the starting motor. Disconnect the cable from
the POSITIVE “+” battery terminal.
Note: Always recycle a battery. Never discard a
battery. Return used batteries to an appropriate
recycling facility.
5. Remove the used battery.
6. Install the new battery.
Note: Before the cables are connected, ensure that
the engine start switch is OFF.
7. Connect the cable from the starting motor to the
POSITIVE “+” battery terminal.
8. Connect the cab
le from the NEGATIVE “-” terminal
on the starting motor to the NEGATIVE “-” battery
terminal.

Battery Electrolyte Level -
Check
When the engine is not run for long periods of time or
when the engine is run for short periods, the batteries
may not fully
recharge. Ensure a full charge in order
to help prevent the battery from freezing. If batteries
are correctly charged, ammeter reading should be
very near zer
o.
All lead-acid batteries contain sulfuric acid which
can burn the skin and clothing. Always wear a face
shield and p
rotective clothing whe n working on or
near batteries.
1. Remove the f
iller caps. Maintain the e lectrolyte
level to the “FULL” mark on the battery.
If the addit
ion of water is necessary, use distilled
water. If distilled water is not available use clean
water that is low in minerals. Do not use artificially
softened w
ater.
2. Check the condition of the electrolyte with a
suitable b
attery tester.
3. Keep the batteries clean.
Clean the battery case with one of the following
cleaning solutions:
•
A mixture of 0.1 kg (0.2 lb) of baking soda and
1L(1qt)ofcleanwater
•
A mixture of 0.1 L (0.11 qt) of ammonia and 1 L
(1 qt) of clean water
Thoroughly rinse the battery case with clean water.
Useafine
grade of sandpaper to clean the
terminals and the cable clamps. Clean the items
until the surfaces are bright or shiny. DO NOT
remove m
aterial excessively. Excessive removal
of material can cause the clamps to not fit
correctly. Coat the clamps and the terminals with
asuitab
le silicone lubricant or petroleum jelly.
