16. TROUBLESHOOTING
16.4 METHODS OF TOWING MACHINE
A
WARNING
I
When using a chain or cable, be sure it is strong enough for the ex-
pected load and it is properly secured to the drawbar pins or tow
hooks (if equipped).
When pulling with a chain or cable, take up the slack slowly to
avoid jerking. A chain or cable which fails under load can whip and
cause serious
injury. Stand clear. Do not pull or tow unless the
operator's
compartment
is guarded against or out of reach of a
whipping
chain or cable. Attach only to the machine tow hook or
drawbar. Failure to follow these instructions
could cause serious
injury.
REMARK
If the steering drive, final drive or tracks are damaged, do not tow. The
machine must be transported on a carrier to avoid further damage.
To avoid the possibility of power train damage, limit the towing to a distance
of 0.8 km (0.5 mile) at speeds less than 1.6 km/h (1 mph). The brakes on this
machine are automaticly
spring applied when the engine is stopped. The
brakes can only be released hydraulically.
A towing port for applying external
pressure to release the brakes is located in the battery box below the drive
train pressure filter.
If the machine can be towed and the engine and steering hydraulic system can
be operated, proceed as follows:
1. Position the safety lock lever in the down position. Start the engine. Use
a towing cable of sufficient strength. Keep the engine running at half
throttle and the safety lock locked in the down position during the tow.
If the machine can be towed but the engine and/or steering hydraulic system
is/are inoperable, proceed as follows:
1. Open the battery box door. Modify a grease gun by installing a female
quick disconnect fitting and a hose of sufficient length to allow operating
the grease gun from the operator's seat for releasing the spring applied
brakes.
REMARK
Do not intermix the male and female quick disconnect fittings with each
other. Refer to Service Bulletin B 07C 89A for proper identification.
2. Pump sufficient
grease into the fitting to release the brakes. The
amount of grease required depends on the amount of pressure of
dissipation in the system.
3. Use a towing cable of sufficient strength. During the tow, it may be
necessary to pump more grease into the brake release fitting to replace
the loss of pressure.
A
WARNING
Stop towing the machine before applying grease to fitting.
4. Depressing the secondary brake pedal will relieve pressure and apply
the brakes. When towing is completed,
remove the grease gun and
close the battery box door.
