3. OPERATION
3.1. Starting
1. Turn the fuel tap down. Turn the ignition
switch to position „ON“.
2. At cold engine:
Close the choke. Set up the throttle lever
into position „OFF“.
At
warm
engine
or
high
ambient
temperature:
Turn the choke lever into the middle
position or leave it fully open. Adjust the
throttle lever slightly above zero.
3. Hold the starting grip and pull a little, until
slight resistance is felt. From this point pull
vehemently. Do not release the grip then, but
return it into the basic position.
4. After the engine gets started, move the
choke lever slowly into the basic position.
Let the engine to warm up at idle speed for
3-5 minutes.
Check, whether there is no gasoline leaks
and whether there is no unusual noise.
5. If the engine does not get started after
several attempts, remove the sparkling plug
and check, whether it emits proper
sparkling. In case the plug is wet from fuel
or dirty, clean or replace it. Rotate the
engine several times before mounting the
plug back, to flush out excessive fuel.
3.2. Operation
1. Set up full throttle quickly to increase the
engine speed. The centrifugal clutch gets
engaged and the temper starts working.
Do not mode the lever slowly - that would
cause irregular operation of the tamper,
which may cause damage to the clutch,
springs and the foot.
2. When the rammer begins to operate, set the
frequency of strikes fine throttle adjustment.
Pech works most effectively when the
engine speed, which are shown on luck.
Unnecessary increase in speed is no longer
any
increase
in
compaction
force.
Conversely, resulting resonance reduces
compaction force and causing damage
3. At cold weather, the oil in the tamper foot is
mode dense and causes higher resistance of
the moving parts. This may cause slightly
irregular operation. In such a case it is
recommended to warm up the machine
before working by repeated increasing and
decreasing the engine speed.
4. The tamper foot is a highly durable
structure. However in case that rockfill
should
be
compacted,
it
is
highly
recommended to put a layer of soil on the
top, in order to ensure even distribution of
compaction effort.
