OPERATION AND SERVICE INFORMATION

Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings.

Periodic Brake Test For Mechanical Brakes

The purpose of this test is to compare the braking per-

formance 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 dis-

tance can be reliably specified. The test is conducted by

latching the park brake to eliminate different pedal pres-

sures and to include the affects of linkage mis-adjust-

ment.

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.

Over time, a subtle loss of performance may take place; there-

fore, it is important to establish the standard with a new vehi-

cle.

Drive the vehicle at maximum speed on a flat, dry, clean,

paved surface (Ref. Fig. 45 on page 27). 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 stop-

ping 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 acceptable 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 TROUBLESHOOTING section in the Technician’s

Repair and Service Manual.

AIR INTAKE AND COOLING FINS

To prevent possible burns, engine parts should

be kept clean to reduce risk of overheating and

ignition of accumulated debris. After every off

road use, allow to cool and then check for a

build up of dirt and debris in the air intake and

cooling fins. Dirt and debris may clog the

engine’s air cooling system. Clean areas

shown to prevent engine damage. Keep linkag-

es, springs and controls clean. Keep area

around muffler free of any combustible materi-

al.

At least once a year, or more often under adverse condi-

tions) the cooling system should be cleaned. Cleaning

will assure an adequate supply of air to the cooling fins.

Compressed air may be used for routine cooling system

maintenance.

REAR AXLE

The rear axle is provided with a lubricant level check

plug located on the driver side at the rear of the housing

(Ref. Fig. 47 on page 29). Unless leakage of rear axle

lubricant is evident, an annual lubricant check is suffi-

cient.

Checking The Lubricant Level

Tool List Qty. Required

Socket, 13 mm, 3/8" drive............................................1

Ratchet, 3/8" drive .......................................................1

Funnel..........................................................................1

Clean the area around the check and fill plugs. Remove

the check plug. The correct lubricant level is just below

the bottom of the threaded hole (Ref. Fig. 47 on page

29). If lubricant is to be added, remove the fill plug and

add lubricant using a funnel. Add lubricant slowly until
