It is important to maintain cleanliness to avoid problems
with the fuel injection system, and to prevent premature
clogging of the fuel filter. To avoid contamination,
DO
NOT
open the fuel line or the fuel pump or any other point
of the fuel system, not even to bleed air. The fuel pump
will bleed automatically. This applies even if the fuel tank
was run dry. If this happens, refill the fuel tank.

strokes. Never allow the rammer to run full throttle when
forcing away material or when lifting the equipment.
CAUTION:
To prevent damage to the rammer, do not
allow the rammer to run on its side.
If the rammer should tip on its side, place the rammer in
the position shown below, then shut off the engine by
moving the throttle control lever through the detent to the
