SAFETY SECTION 1
DD-29/31HF/38HF Vibratory Asphalt Compactors 1-9
NEVER allow anyone to stand within the compactor’s articulation area when the engine is
running.
ALWAYS LOOK in all directions BEFORE changing your direction of travel.
CONTROL the compactor travel speed with the LOW/HIGH speed control. When operating
the compactor maintain the engine speed at full “Operating RPM.”
DO NOT tow or push the compactor except as explained in Section 4 of this manual.
DO NOT release the brake(s) with any hydraulic or mechanical means prior to towing without
tagging the compactor with a BRAKE RELEASED tag.
DO NOT run the engine in a closed building for an extended length of time. EXHAUST FUMES
CAN KILL.
Stopping
ALWAYS park the compactor on solid level ground. If this is not possible, always park the
compactor at a right angle to the slope and chock the wheels and drum.
AVOID leaving the operator’s platform with the engine running. ALWAYS move the propulsion
(travel) control to “STOP”, apply the parking brake, install the articulation lock bar/lock pin,
position the throttle control to “idle RPM”, pull the fuel shut-off control (if so equipped), turn
ignition switch to OFF, and lock all lockable compartments.
USE proper flags, barriers, and warning devices, especially when parking in areas of heavy
traffic.
Maintenance
In any work concerning the operation, conversion or adjustment of the machine and its safety
oriented devices or any work related to maintenance, inspection and repair, always observe
the start up and shutdown procedures set out in the operating instructions and the information
on maintenance work.
ENSURE that the maintenance area is adequately secured.
If the machine is completely shut down for maintenance and repair work, it must be secured
against inadvertent starting by:
• locking the principal control elements and removing the ignition key and/or
• attach a warning sign to the main switch
CARRY OUT maintenance and repair work only if the machine is positioned on stable and
level ground and has been secured against inadvertent movement and buckling.
USE CARE when attaching and securing lifting tackle to individual parts and large assemblies
being moved for replacement purposes to avoid the risk of accidents. USE lifting gear that is
in perfect condition and with adequate lifting capacity. NEVER work or stand under suspended
loads.
