Engine
Refer to the engine manual for location of all controls and
features.
Starting Gasoline Engine
1. Open fuel valve.
2. Turn engine switch to “ON” position.
3. Set throttle to idle position.
4. Choke engine if necessary (you may not need to
choke a warm engine).
5. Pull starter rope repeatedly until engine starts.
6. Move choke lever to off or open position.
7. Allow engine to warm up for one or two minutes.
Starting Diesel Engine
For detailed instructions refer to the engine Manual.
1. When starting the engine, the throttle lever on the
handle must be in the idle position.
2. The engine has an automatic decompression
system, however it is recommended to slowly pull the
starter rope until you feel a slight resistance. Let the
starter rope recoil completely and pull the starter rope
quickly.
3. Let the engine warm up in the idle position for one or
two minutes.
Operating
1. After the engine warms up, fully open throttle.
2. The compactor will begin vibrating and moving in a
forward direction.
Never leave compactor idling
unattended.
3. The MBW Reversible Plate Compactor is designed to
shift into forward automaticly when control lever is
released. The number of passes needed to reach the
compaction level desired will depend on soil type and
moisture. Maximum compaction of the soil has been
reached when excessive kickback is noticed in the
compactor.
