1.13 Selecting Ramming Stroke
The length of the ramming stroke directly affects the
impact force delivered by the rammer. Selecting the best
level depends on job requirements and soil conditions.
The label located inside the front cover indicates the
general compaction application, together with approxi-
mate throttle settings and impact levels for each stroke
level. It should be used as a general guide when
selecting ramming stroke.

1.11 To Stop
1. Place throttle in “IDLE”
(c

)
.
2. Shut off engine by closing fuel valve
(a

)
on tank.
1.12 Proper Operation
1. Open throttle completely
(c
3
)
, then adjust for the
smoothest operation. Do not overthrottle. Best com-
paction is achieved when rammer is running smoothly.
Normally, a low stroke setting requires a lower engine
speed.
CAUTION:
Running the engine too fast will result in
poor operation and unnecessary wear to compo-
nents.
2. Guide rammer with handle.
Allow machine to pull
itself forward.
DO NOT
try to overpower the machine.
3. For best compaction, shoe must hit the ground flat
(g)
, not on its toe or heel. This will save on excessive
shoe wear.
