MAINTENANCE, LUBRICATION AND SERVICE
CAB MAINTENANCE
Cab Air Filter
To provide comfortable and clean fresh
air in the cab, the heating and air
conditioning system is designed with a
replaceable lter.
Under normal operating conditions the
lter should be replaced every 6 months
to ensure the efciency of the heating
and air conditioning system. Failure to
replace the lter may cause damage to
heater/AC components.
Dusty conditions may require more
frequent replacement.

Doors
The door lock mechanism should be
greased annually using white grease.
Lubricate the door lock cylinder with
liquid graphite annually, or more often in
climates with a lot of snow and salt on
the roads. On wet and salted roads,
road spray can enter the door lock key
cylinder. Lubricate the cylinder with
liquid graphite annually or more often if
necessary. The door hinge pins are
treated at manufacturing and then
sealed. No lubrication is necessary. To
keep the door rubber moldings and
seals around the windows in good
working order and to prevent them from
freezing shut during the cold season,
occasionally spray on a silicone
compound.
