GENERAL INFORMATION
All safety rules in Section 1 must be observed. If further information is required concerning the
recommended use on asphalt applications, contact your local distributor or the following.
The manufacturer reserves the right to make changes or modifications without prior notice and
without incurring any liability to retrofit machines previously shipped from the factory.
MACHINE DESCRIPTION
Each compactor model offers the ideal combination of weight, drum width, frequency,
centrifugal force and amplitude. The combination of these specifications results in the most
efficient compaction of hot mix asphalt (H.M.A.) and non-cohesive soils.
DD-29 / DD-31HF / DD-38HF Compactors feature the Kubota V2203M engine and hydrostatic
propulsion and steering systems. The hydrostatic propulsion system drives both drums for
maximum gradeabilty.
DRUMS
To meet varying job requirements, the operator can manually control drum vibration or static
and select dual drum or front drum.
DD-29 Compactor has an eccentric speed (the vibration power driving the drums) set at 4000
vibrations per minute (66.47 Hz).
DD-31HF and DD-38HF Compactors have the eccentric speed (the vibration power driving the
drums) set at 4200 vibrations per minute (70 Hz).

ENGINE
All Models have the following features:
• Electric starting, belt driven alternator and battery are standard.
• A dry type, two-stage air cleaner system provides clean air to the engine. A dust
discharging evacuator valve is provided on the air cleaner.
• Engine RPM is controlled by the throttle lever located on the pedestal. The engine is
shutdown by either turning the ignition switch OFF or, in an emergency, by pressing
the emergency stop switch.
DD-29 / DD-31HF / DD-38HF machines use water-cooled, heavy-duty, industrial diesel
engines with 44 hp (32.8 kW) @ 2450 RPM.
MAIN FRAME
The machine consists of a front and rear frame which are connected by the swivel joint. The
front frame includes an engine with drive pump and the hydraulic tank. The rear frame includes
the seat and control console, water tank system, and fuel tank.
CONTROLS
All of the controls are positioned for operator convenience. The control panel contains the
following standard controls and indicators: drum selector switch, hourmeter, emergency stop
pushbutton, horn button, check engine light, brake test switch, and park brake switch with
indicator light. In addition to the standard controls, there are controls for three options:
pressurized water spray, driving lights, and beacon. All controls have ISO symbols indicating
their functions.
Hand rails, skid-resistant decking, and toe plates promote safety.
Refer to Section 3 of this manual for a complete description of the controls and indicator lights.
DRUM WATER SPRAY SYSTEM
A pressurized water spray system is standard. A knob located on the pedestal controls the
amount of water to the drums. The system consists of a separate pump, spray bars, and hand-
serviceable nozzles. The system can be operated in automatic mode, manual mode, or turned
OFF when water spray is not required. The flow control permits added productivity over
competitive models by allowing the operator to adjust and conserve water sprayed on the
drums, thus, avoiding costly down time.

DD-29/31HF/38HF Vibratory Asphalt Compactors 7
BRAKES
Service brakes are dynamic hydrostatic through the propulsion system. The secondary brakes
are spring-applied, hydraulically released and are incorporated on both the front and rear
drums for safety, reliability and maintenance-free operation. The secondary brakes activate
automatically in the event of a power loss or can be activated by the operator with the park
brake switch or E-Stop switch.
SERVICEABILITY
A light weight hood lifts to provide easy access to the engine, filters, and hydraulic
components. The spring loaded drum wipers require little maintenance. A removable panel
provides additional access for extensive repair.
ROPS/SEAT BELT
The manufacturer provides ROPS (rollover protective structure) and seat belts as standard
equipment on all compactors. A foldable ROPS is available as optional equipment. ROPS
used in conjunction with seat belts will lessen the possibility of death or serious injury in the
event of a rollover.
WARNING
!
Your life may be endangered if the following are not complied with:
DO NOT operate this machine if the Rollover Protection Structure (ROPS)
is structurally damaged, show cracks, is not properly secured as
originally installed, or has been involved in a rollover.
DO NOT repair, modify, drill, weld on or add attachments to the ROPS
unless authorized in writing by the manufacturer.
DO NOT operate the machine unless the seat belt conforming to SAE
and/or ASAE standards is fastened.
Contact your dealer for complete inspection requirements and
maintenance instructions.

GENERAL
The manufacturer can not foresee all possible circumstances that might lead up to a potential
hazard. Therefore, the combination of warnings listed in this manual and those placed on the
machine itself are not intended to be all inclusive. Operators and maintenance personnel must
be alert to recognize and avoid potential hazards. They should also have comprehensive
training, required skills and necessary tools to properly perform their functions.
The machine was built in accordance with state-of-the-art standards and recognized safety
rules. Nevertheless, its misuse may constitute a risk to life and limb of the user or of third
parties, and may cause damage to the machine or other material property.
The machine must be used in accordance with its designated use as described in the
operating and control sections of this manual. The machine must only be operated by
safety-conscious persons who are fully aware of the risks involved in operating the machine.
Any functional disorders, especially those affecting the safety of the machine, must be
corrected immediately.
The machine is designed exclusively for the compaction of asphaltic road construction
materials. Use of the machine for purposes other than that mentioned (such as for towing other
vehicles/equipment) is considered contrary to its designated use. The manufacturer/supplier
cannot be held liable for any damage resulting from such use. The risk of such misuse lies
entirely with the user.
Operating the machine within the limits of its designated use also involves compliance with the
inspection and maintenance directives contained in the operating section of this manual.

SUPPLEMENT operating instructions with detailed working instructions pertaining to the
specific work location.
ALWAYS be sure that persons entrusted with work on the machine have read the operating
instructions and in particular the chapter on safety before beginning work. Reading the
instructions after work has begun is too late. This is especially important for persons who work
only occasionally on the machine, e.g. during set up or maintenance.
MAKE CERTAIN personnel are working in compliance with the operating instructions and are
alert to risks and safety factors.
ALWAYS tie back or otherwise secure long hair, wear close-fitting garments and avoid
wearing jewelry such as rings. Injury may result from clothing, hair, or jewelry being caught up
in the machinery.
USE protective equipment wherever required by the circumstances or by law.
OBSERVE all safety instructions and warnings attached to the machine.
BE SURE all safety instructions and warnings attached to the machine are complete and
perfectly legible.
STOP the machine IMMEDIATELY in the event of any malfunction. REPORT the malfunction
to the proper authority/person.
