288 Service and Maintenance
O: Glass, Mirrors, Lights and/or
Reflectors Condition : Look for
broken, scratched, dirty or damaged
glass, mirrors, lamps or reflectors
that could reduce the view or
visibility, or cause injury. Replace,
clean or repair promptly.
P: Door Latches : Check that doors
close, latch and lock tightly. Check
for broken, damaged or missing
parts that might prevent tight
latching.
Q :Tilt Cab (Driving Position) : Be
sure the tilt lever is down and
locked.
R: Fluid Leaks : Check for fuel,
water, oil or other fluid leaks by
looking at the surface beneath the
vehicle after it has been parked for
a while. If you notice gasoline fumes
or fluid at any time, have the cause
found and corrected at once.
S: Underbody : Corrosive materials
used for ice removal, snow removal
and dust control can collect on the
underbody. If these materials are
not removed, accelerated corrosion
(rust) can occur on underbody parts
such as fuel lines, frame, floor pan
and exhaust system. At least every
spring, flush these materials from
the underbody with plain water.
Take care to clean well any areas
where mud and other debris can
collect. Sediment packed in closed
areas of the frame should be
loosened before being flushed.
Checking Components that
Showed Abnormalities during
Previous Operation
Check the components that showed
abnormalities during the previous
operation. Have any abnormalities
repaired by your dealer before using
the vehicle.
