Maintenance - Hitachi CG 23ECP (SL) Manual De Instrucciones

English
● Do not use with the engine set at low
speeds. If the engine speed is low, grass
may wrap around the attachment, causing
the clutch to slip which could result in clutch
abrasion.
● With nylon cord cutters, always use over
5-7/8" (15 cm) of cord. If the length of
the cord is too short, rotation speed will
increase and may cause damage to the
nylon cord cutter. As the curved drive shaft
tube model in particular is not equipped with
a deceleration mechanism, the possibility
of increased rotation speed for the cutting
attachment is high.
Stopping (Fig. 15)
Decrease engine speed and run at an idle for a few
minutes, then turn off ignition switch (10).
WARNING
A cutting attachment can injure while it
continues to spin after the engine is stopped
or Throttle trigger is released. When the
unit is turned off , make sure the cutting
attachment has stopped before the unit is
set down.

MAINTENANCE, REPLACEMENT OR REPAIR
OF THE EMISSION CONTROL DEVICES AND
SYSTEMS MAY BE PERFORMED BY ANY NON-
ROAD ENGINE REPAIR ESTABLISHMENT OR
INDIVIDUAL.
Carburetor adjustment (Fig. 16)
WARNING
● The cutting attachment may be spinning
during carburetor adjustments.
● Never start the engine without the complete
clutch cover and tube assembled! Otherwise
the clutch can come loose and cause
personal injuries.
In the carburetor, fuel is mixed with air. When the
engine is test run at the factory, the carburetor is
basically adjusted. A further adjustment may be
required, according to climate and altitude. The
carburetor has one adjustment possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air fi lter is clean. Be sure the cutting
attachment stop turning when the engine idle. When
the idle speed is correct, the cutting attachment
will not rotate. If adjustment is required, close
(clockwise) the T-screw, with the engine running,
until the cutting attachment starts to rotate. Open
(counter-clockwise) the screw until the cutting
attachment stops. You have reached the correct
idle speed when the engine runs smoothly in all
positions well below the rpm when the cutting
attachment starts to rotate.
If the cutting attachment still rotates after idle speed
adjustment, contact Hitachi Authorized Service
Centers.
NOTE
Standard Idle rpm is 3,000 – 3,400 min
