Maintenance Section
Battery or Battery Cable - Disconnect
All lead-acid batteries contain sulfuric acid which
can burn the skin and clothing. Always wear a
face shield and protective clothing when working
on or near batteries.
1. Remove the filler caps. Maintain the electrolyte
level to the "FULL" mark on the battery.
If the addition 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 water.
2. Check the condition of the electrolyte with a
suitable battery tester.
3. Install the caps.
4. Keep the batteries clean.
Clean the battery case with one of the following
cleaning solutions:
• Use a solution of 0.1 kg (0.2 lb) baking soda
and 1 L (1 qt) of clean water.
• Use a solution of ammonium hydroxide.
Thoroughly rinse the battery case with clean
water.
Battery or Battery Cable -
Disconnect
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. Turn the start switch to the OFF position. Turn the
ignition switch (if equipped) to the OFF position
and remove the key and all electrical loads.
2. Disconnect the negative battery terminal. Ensure
that the cable cannot contact the terminal. When
four 12 volt batteries are involved, two negative
connection must be disconnected.
3. Remove the positive connection.
4. Clean all disconnected connection and battery
terminals.
5. Use a fine grade of sandpaper to clean the
terminals and the cable clamps. Clean the items
until the surfaces are bright or shiny. DO NOT
remove material excessively. Excessive removal
of material can cause the clamps to not fit
correctly. Coat the clamps and the terminals with a
suitable silicone lubricant or petroleum jelly.
6. Tape the cable connections to help prevent
accidental starting.
7. Proceed with necessary system repairs.
8. To connect the battery, connect the positive
connection before the negative connection.
Cooling System Coolant
(Commercial Heavy-Duty) -
Change
Note: This procedure is for coolants that meets a
commercial heavy-duty coolant specification of
"ASTM D6210" .
Clean the cooling system and flush the cooling
system before the recommended maintenance
i07819485
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
When any servicing or repair of the engine cooling
system is performed, the procedure must be per-
formed with the engine on level ground. Level ground
will allow you to check accurately the coolant level.
This procedure will also help in avoiding the risk of in-
troducing an air lock into the coolant system.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. This inspection is a good opportunity
to replace the water pump, the water temperature
regulator, and the hoses, if necessary.
