WARNING
If the diamond abrasive chain continues
to keep rotating in idle even after
adjustment, have the concrete cutter
checked by a servicing dealer.
Speed erratic when idling; poor
acceleration (despite low speed
screw = 1/4)
N Idle speed setting is too lean – turn
the low speed adjusting screw (L)
counterclockwise until the engine
runs and accelerates smoothly
Whenever the low speed adjusting
screw (L) has been adjusted, it is usually
also necessary to readjust the idle
speed adjusting screw (LA).
Correcting the carburetor setting for use
at high altitudes
The setting may have to be marginally
corrected if engine performance is
unsatisfactory at high altitudes:
N Check standard setting
N Let the engine warm up
N Turn the high speed adjusting
screw (H) slightly clockwise (leaner)
– max. up to the stop
NOTICE
After descending from a high altitude,
restore the carburetor setting to the
standard setting.
If you make the setting too lean it will
increase the risk of engine damage
through lack of lubrication and
overheating.
In some countries, the muffler is fitted
with a spark arresting screen.
N If engine performance deteriorates,
check the spark arresting screen in
the muffler
N Let the muffler cool down
N Remove four screws
N Remove exhaust casing (1) of the
muffler
N Bend back the retaining lugs (2)
N Pull out spark arresting screen (3)
N Clean the dirty spark arresting
screen, replace if damaged or
heavily carbonized
N Refit the spark arresting screen in
reverse order of steps
