RAMMER
OPERATOR’S MANUAL

OPERATING
Follow the steps below while operating the rammer.
1.
Move the throttle lever quickly from IDLE to OPERATING position to start the tamping
action.
CAUTION
DO NOT
move the throttle lever
slowly
as this may cause damage to the clutch
or spring and unstable performance of the Rammer may result.
2.
After starting tamping action, adjust the jumping stroke motion to suit the soil conditions
by lightly controlling the throttle lever. When the engine speed falls between the set
values shown on the engine, your work can be carried out at the best efficiency and
effectiveness.
3.
When operating, guide the Rammer with both hands, but allow the machine to do the
work. Bearing down on the handle is unnecessary and limits the bottom plate ramming
action.
4.
The tamping rammer is designed to tamp the ground at 600 to 695 times per minute
(640 to 680 times per minute for diesel engine) at an engine speed of 3600 rpm.
Increasing the speed above the recommended rpm will not increase rammer
effectiveness.
Impact force will actually decrease because a resonance is created
rather than increasing the tamping effect. This resonance may damage the unit.
5.
In cold weather, the oil in the machine becomes viscous and may cause greater
resistance at the reciprocating part, resulting in irregular movement. Therefore, it is
recommended to perform a warm-up run by moving the throttle lever from OPERATING
to IDLE position quickly and continuously for several minutes before entering the work.
6.
The soil-contacting surface of the foot is lined with a heat-treated metal sheet for extra
strength. For compacting cobblestone, use soil to fill cracks so that the foot hits the
surface uniformly.
7.
Always guide the rammer so that the entire bottom plate, and not just the front or back
edge, does the impacting.
8.
The machine is designed to travel forward while tamping. To increase the travel speed, a
slight back-pull to the handle is necessary so that the rear of the foot contacts the soil
first, giving extra forward thrust to the rammer. On uneven surfaces or inclines, rocking
the handle slightly may assist the rammer in moving forward.
9.
As the soil becomes compacted, the jump height of the rammer will increase.
