Engine oil
Check oil level:
Tilt the machine backwards approx. 15° until the engine
is level by placing a wedge under the shoe. The oil
surface should reach NO HIGHER THAN the bottom of
the filler neck “H”, but no lower than “L” (see drawing) or
visible on the dipstick
(f)
when it is inserted (not screwed)
into the filler neck.
Add CC or better quality oil through the filler neck as
required.
CAUTION:
DO NOT
overfill. The oil level should just
reach the bottom of the filler neck. Too much oil can
cause damage to the engine and the rammer.
Note:
After transporting the rammer horizontally, upright
the rammer and allow the oil to drain back through the
engine. It may take up to 45 minutes for the oil level to
recover.
Oil filter:
1. Drain the oil as above.
2. Unscrew the bolt
(h)
on the oil filter cover and pull out
the oil filter.
To clean the oil filter:
Use low pressure compressed air to remove any
visible debris on the oil filter.
To replace the oil filter:
Discard the old oil filter in accordance with environ-
mental regulations. Replace with WACKER-supplied
oil filter and O-ring.
