2. To achieve uniform running you should actuate the throttle
lever within the working range (I), depending on condition
and density of the soil.
ð Working range (I) = 3600 to 4200 min -1
3. If the machine jumps out of rhythm on heavily compacted
soil, you may need to slightly change the engine speed
and/or inclination of the tamper.
NOTICE!
The centrifugal clutch may be damaged!
– Do not work with engine speeds which are
below the working range.
4. If the display [LOW] appears, increase the engine speed.
5. Adapt the marching speed by applying load to the guide
handle:
(A) No load - slowly forward
(B) Heavy load - fast forward
6. Always shift the throttle lever to position “MIN” for short work
breaks.
