Rammer
Operation
Continued from the previous page.
Note: Choosing a stroke setting applies tension to the spring system. This tension
will release as the locking lever is returned back to its locked position. When this
happens, the rammer will settle, causing the handle and crankcase to drop down.
The movement is slight but happens quickly. Be aware of this when moving the
locking lever.
5. Push or pull the adjusting tool to move the locking lever back to its locked
position (Operation 3). When the locking lever is halfway between the locked
and unlocked position, the spring system will settle and move as described in
the warning above.
6. Remove the adjusting tool. Close the housing cover and lock it in place with the
adjusting tool.
Result The ramming stroke has now been selected. Operate the machine at the
corresponding throttle setting as shown on the chart below.

The label located inside the housing cover indicates the general compaction
application, together with approximate throttle settings and impact levels for each
stroke level. It should be used as a general guide when selecting the appropriate
ramming stroke.
