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 Authorized 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 work site or on a roadway, prepare 
the machine for towing as follows:
1. Remove the load from the machine.
2. Fully retract the transfer carriage.
3. Fully retract the boom. Position the forks
approximately 24 in (607 mm) above the ground. 
Refer to Section 3.9, “Emergency Boom Lowering,” if 
needed.
