OPERATING INSTRUCTIONS
Towing the compactor is limited to off the job site, onto the transporter,
off the transporter, and into the shop.
The machine used to tow the compactor should be heavier than or equal
to the weight of the compactor being towed.
When towing, use a chain rated for a minimum of 13.6 metric tons (15
tons). Tow only on level ground or up a slight grade. Since the compactor
braking system has been disabled, the towing machine is the only means
of restraining the compactor while being towed.

Refer to Transporting, Towing and Roading in Section 1 before
transporting the compactor.
In the event of an engine problem or other malfunction, it may become necessary to tow your
compactor.
Towing the compactor requires bypassing the propulsion pump and releasing the spring-
applied brakes. Procedures to do so are described below.
NOTE: The propulsion pump is designed with a bypass function that consists
of two multi-function valve cartridges used to disengage the propulsion system.
In order to tow the compactor, the propulsion pump must be disengaged and the spring-
applied brakes must be released.
The spring applied brake will always be applied when the engine is not running unless it is
manually released.
The release of the spring-applied hydraulic brakes requires the use of a manually operated
directional control valve (1, Figure 4-34 mounted to the brake valve solenoid positioned on the
3-section manifold (2, Figure 4-34). The manifold is bolted to the back wall of the battery
compartment. A second manually operated check valve, (3, Figure 4-34).
1. Chock the drum and wheels.
2. Ensure that the Parking BRAKE control is in the "applied" position.
3. Open the battery compartment.
4. Remove the Warning Tag (Figure 4-33).
