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
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
system before the recommended maintenance
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.
Note: When the cooling system is cleaned, only
clean water is needed.
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.
Drain
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
