Owner’s Manual and Service Guide
Read all of manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings
All driving brake tests must be done in a safe
location with regard for the safety of all person-
nel.
Over time, a subtle loss of performance may
take place; therefore, it is important to establish
the standard with a new vehicle.
The Periodic Brake Performance Test should be per-
formed regularly (Ref. Fig. 21 on page 17) as an evalua-
tion of braking system performance. It is useful as a
method of identifying subtle loss of performance over
time.
PERIODIC BRAKE TEST FOR MECHANICAL
BRAKES
The purpose of this test is to compare the braking perfor-
mance of the vehicle to the braking performance of new
or ‘known to be good’ vehicles or to an established
acceptable stopping distance. Actual stopping distances
will be influenced by weather conditions, terrain, road
surface condition, actual vehicle weight (accessories
installed) and vehicle speed. No specific braking distance
can be reliably specified. The test is conducted by latch-
ing the park brake to eliminate different pedal pressures
and to include the affects of linkage mis-adjustment.
Establish the acceptable stopping distance by testing a
new or ‘known to be good’ vehicle and recording the
stopping location or stopping distance. For fleets of vehi-
cles, several vehicles should be tested when new and
the range of stopping locations or distances recorded.
Drive the vehicle at maximum speed on a flat, dry, clean,
paved surface (Ref. Fig. 21 on page 17). Quickly depress
the brake pedal to latch the parking brake at the line or
marker in the test area and remove foot from pedal. The
vehicle should stop aggressively. The wheel brakes may
or may not lock. Observe the vehicle stopping location or
measure the vehicle stopping distance from the point at
which the brakes were latched. The vehicle should stop
within the ‘normal’ range of stopping distances. If the
vehicle stops more than 4 ft. (1.2 m) beyond the accept-
able stopping distance or pulls to one side, the vehicle
has failed the test and should be tested again.
If the vehicle fails the second test, it should immediately
be removed from service. The vehicle must be inspected
by a qualified mechanic who should refer to the TROU-
BLESHOOTING section in the Technician’s Repair and
Service Manual.
REAR AXLE
The rear axle is provided with a lubricant level check/fill
plug located on the bottom of the differential. Unless
leakage is evident, no maintenance is required.
CHECKING THE LUBRICANT LEVEL
Clean the area around the check/fill plug and remove
plug. The correct lubricant level is just below the bottom
of the threaded hole. If lubricant is low, add lubricant as
required. Add lubricant slowly until lubricant starts to
seep from the hole. Install the check/fill plug. In the event
that the lubricant is to be replaced, the oil pan must be
removed or the oil siphoned through the check/fill hole
(Ref. Fig. 22 on page 18).
LUBRICATION
Do not use more than three (3) pumps
of grease in any grease fitting at any
one time. Excess grease may cause grease seals to fail or
grease migration into areas that could damage components.
Putting more than three pumps of grease in a grease fit-
ting could damage grease seals and cause premature
bearing failure (Ref. Fig. 23 on page 18).
