1.14 Adjusting Ramming Stroke
When adjusting the ramming stroke, observe the following precautions to avoid injury to yourself and others.
To adjust ramming stroke:
1. Remove adjusting tool from cover. Open cover.
2. Check that arrow
(a)
on center of locking lever is
pointing up.
3. Insert adjusting tool
(b)
into bore on locking lever.
Make sure it is fully seated so it will not slip out. Steady
rammer by holding guide handle and use adjusting
tool to push locking lever straight down until it is
completely disengaged (refer to Operation 1 in illus-
tration above).
4. Using adjusting tool, move locking lever until center
arrow is pointing at the desired stroke setting (Opera-
tion 2).
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 warning above.
6. Remove adjusting tool. Close cover and lock it in
place with tool.

-
Adjust stroke with machine standing upright and resting on a firm, level surface. Do not adjust stroke if the
machine is in an unstable position where it can easily tip or slide.
-
Always stop engine before adjusting stroke. The clutch could engage, causing rammer to jump unexpectedly.
-
Adjustment should be performed by one person and with no one else near the machine. The tool used to make
the adjustment could slip out of your hands and hit someone standing nearby.
During this adjustment, tension is applied 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 locking lever.
If arrow is pointing down, the spring system is not
balanced and could cause the top half of the rammer
to drop unexpectedly while making the stroke adjust-
ment. To balance spring system, stand behind the
rammer and use guide handle to rock machine back
and forth until you feel the spring system relax. The
arrow should now be facing up.
