OPERATING INSTRUCTIONS SECTION 4
DD-29/31HF/38HF Vibratory Asphalt Compactors 4-23
In the event of an engine problem or other malfunction, or if the engine will not start, 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.
The spring-applied brake will always be applied when the engine is
running unless it is manually released.
1. Chock the drums.
2. Remove plastic plug (1, Figure 4-31) from the center of each drum drive motor
housing (2).

3. Disassemble the brake release bolts (1, Figure 4-32), nuts (2) and bars (3) from
the drum support legs (4).
4. Assemble the nut and washer (2, Figure 4-32) onto the bolt (1) and place the
bolt through the hole in the release bar (3).
5. Thread the bolt into the hole in the housing (2, Figure 4-32) until it bottoms out.
Then, tighten the nut against the bar until the brake releases.
