Precautions for Towing
d
WARNING: Never attempt to tow the machine if the
brake system is in need of repair. Ask your nearest
authorized dealer to repair the machine. Operate the
machine only after repair is completed.
Avoid towing the machine as much as possible. If the
machine is to be unavoidably towed, beware of the
following points.
IMPORTANT: Do not tow the machine with the parking
brake applied. Damage to the parking brake may
result.
 If the engine is operable:
Keep the engine running so that the steering and brake
system are operable. Release the parking brake.
 If the engine is inoperable:
Removing the propeller shaft
 When the parking brake cannot be released, manually
release the parking brake. (Refer to the "Releasing Parking
Brake" on page 6-7.) Then, disconnect the front and rear
propeller shafts. At this time, wedge wheel stoppers to all
tires to prevent the machine from moving.
 The steering system is inoperable when the engine is
stopped. Changing the hydraulic hose connections
between the rod end side and the head end side only
of one steering cylinder enables the steering wheel
operation.
f
NOTE: Take care not to spill oil when disconnecting the
hoses.
