WARNING
Turn off the engine and place the igni-
tion switch in the OFF position before
disconnecting the battery clamps. DO
NOT place any tools or other materials
on top of or close to the batteries. This
can cause a dangerous high current
short circuit and, in the worst case, a
battery explosion. Keep all objects
away from the battery terminals. Al-
ways break the contact between the
battery clamp and the negative termi-
nal before working on the vehicle.
Working on a vehicle while the battery
is connected may result in electrical in-
jury or damage. Always disconnect the
battery at the negative terminal when
performing service procedures. Failure
to comply may result in death, person-
al injury or equipment damage.
WARNING
Electrical shock hazard: Never discon-
nect the battery clamp when the en-
gine is running. Disconnecting the bat-
tery clamps while the engine is running
may result in death, personal injury or
equipment damage from electrical arc-
ing or damage to electrical compo-
nents.
1. Disconnect the chassis battery
cable at the negative battery
terminal.
2. Place an oil collection pan directly
under the oil filter.
Oil Filter Removal
Follow the procedure below after reading
"Oil Filter Removal Preparation."
1. Clean the oil filter cap and
surrounding area to ensure dirt
does not fall into the oil filter
module.
CAUTION
Dirt in the engine oil lubrication system
can lead to significant damage to the
engine. Failure to comply may result in
equipment or property damage.
2. Remove the screw cap with the
centrifugal oil filter from the oil
module. Use a hexagonal socket or
a box wrench to avoid damaging
the oil filter cap.
