Fluid Levels
Checking Percussion System Oil
Refer to Lower Unit Assembly, page 16.
The rammer percussion system and gearbox are lubricated
by an oil mist which is formed and carried throughout the
rammer by a pumping action in the machine's lower system.
1. Before daily operation, place the rammer on a flat
surface and check the oil level in the glass sight (#12)
on the spring box (#14).
2. If the oil is not visible in the sight gauge, add oil as
required. See Fluid Levels above for recommended
type of oil.
Changing Percussion System Oil
Refer to Lower Unit Assembly, page 16.
1. Tip the rammer backward so the handle is on the
ground.
2. Remove the pipe plug (#19) below the sight glass
(#12) on the back of the spring box (#14).
3. Place an oil pan under the drain hole.
4. Rotate the rammer to drain the oil into the oil pan.
The gearbox may need to be elevated to get all of the
oil to drain.
5. Replace the pipe plug.
6. Lay rammer with valve side down.
7. Remove the pipe plug (#33, page 14) next to the
breather on the top of the gearbox.
8. Fill the system with oil. See Fluid Levels above for
recommended type and quantity of oil.
