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 at the
battery that goes to the start switch. Ensure that
the cable cannot contact the terminal. When four
12 volt batteries are involved, the negative side of
two batteries must be disconnected.
3. Tape the leads in order to help prevent accidental
starting.
4. Proceed with necessary system repairs. Reverse
the steps in order to reconnect all of the cables.

Cooling System Coolant -
Change
Illustration 22
Do not drain the coolant while the engine is still hot and
the system is under pressure because dangerous hot
coolant can be discharged.
Note: The radiator may not have been provided by
Perkins. The following is a general procedure for
changing the coolant. Refer to the OEM information
for the correct procedure.
1. Ensure that the vehicle is on level ground.
2. Remove the filler cap of the cooling system.
3. Remove the drain plug (1) from the side of the
cylinder block in order to drain the engine. Ensure
that the drain hole is not restricted.
4. Open the radiator drain tap or remove the drain
plug at the bottom of the radiator in order to
drain the radiator. If the radiator does not have a
radiator drain tap or a drain plug, disconnect the
hose at the bottom of the radiator.
5. Flush the coolant system with clean water.
6. Install the drain plugs and close the radiator drain
tap. Install the radiator hose if the radiator hose
was previously removed.
