5.9 TOWING A DISABLED MACHINE
Towing a disabled machine should only be attempted as
a last resort, after exhausting all other options. Make
every effort to repair the machine, and move it under its
own power. Towing the machine improperly can result in
damage to the machine drivetrain.
Note: In the event the machine is disabled and cannot
be moved under engine power, the situation must be
properly evaluated and dealt with on an individual basis.
Contact your local JLG distributor for specific instructions
for your particular situation.
If it is necessary to tow the machine a short distance to
avoid a potentially hazardous situation such as being in
an unsafe area on the worksite or on a roadway, prepare
the machine for towing as follows:
1. Remove the load from the machine.
2. Block all four wheels to help prevent the machine
from moving after the parking brake is disabled.
3. Remove the transmission covers.
4. Position the towing vehicle in place. Attach any
chains needed to secure the disabled machine.
5. Attach a remote portable hydraulic pressurizing unit
to the parking brake gauge port (5) on the secondary
function manifold (6) mounted on the inside wall of
the frame on the left side next to the transmission.
6. Turn the key switch to the ON position, release the
park brake, and have an operator seated in the seat.
7. Pressurize the park brake with the pressurizing unit.
Close the pump needle valve on the pressurizing
unit.
8. Clear the area of all unnecessary personnel.
9. Remove the blocks from the wheels. Tow the
machine to a secure location.
10. Remove the hydraulic pressurizing unit.
Note: Without engine power, service brake power is
reduced. Only the rear service brakes will function when
the brake pedal is depressed. Steering is not possible
and the machine will only travel in the direction that the
wheels were last turned. Tow or push the machine at a
very slow speed.
