ADJUSTING
Lift up lever type
(DG927, DG935 &
DG945)
Choke lever type
(DG953)
Idling Speed
• If the cutting blade move when the engine is
running at the idle speed, turn the idle screw
counterclockwise to decrease the engine idle
speed.
• If the engine does not run the idle speed, it
may be changed too low, turn the idle screw
clockwise to increase the engine idle speed.
The stable idle speed for DG927 & DG935 it’s
3000 rpm. For DG945 & DG953 it’s 2800 rpm.
Fuel adjustment
The carburetor has been adjusted to the opti-
mum fuel supply at the factory. Don’t reset the
carburetor setting.
NOTE: If adjustment is needed, it should be
performed by your authorized service center.
STOPPING
(Fig.10)
• Move the throttle lever on the equipment to
the fully CLOSED (engine idle speed) position,
and the engine running at idle speed.
• Turn the engine switch to the “0” (stopping)
position.
IMPORTANT: Suddenly stopping engine
from highspeed operation can causeengine-
damage. Reduce engine speed to idle speed
for one minute before shutting engine off af-
ter high-speed, full-load operation.
CATALYTIC CONVERTER
(except DG953)
This small engine is equipped with a catalytic
converter in the exhaust system to signifi-
cantly reduce exhaust emissions. The catalytic
converter converts carbon monoxide and hy-
drocarbons into harmless carbon dioxide and
water.
The catalytic converter requires special care.
• Use only unleaded gasoline. Never use leaded
gasoline. Leaded gasoline significantly reduces
the capability of the catalytic converter.
• Do not use 2-stroke oil that contains Phos-
phorus (P), Lead (Pb), or Sulfur (S). These ele-
ments wil l reduce the life and performance
ofthe catalytic converter.
• Before shutting the engine off, allow it to
idle for a short while.
IMPORTANT: Never stop the engine by clos-
ing the choke lever.
• Never stop the engine during operation
while running above idle speed.
· Shut off the engine and allow it to cool be-
fore transporting or storing the unit.
· Do not put the unit on dry grass or near any
flammable object unless the engine is cold or
cooled down.
OPERATING THE TRIMMER
WARNING: Always place the motor head to
your right side. If you place the trimmer motor
on your left side, you will be exposed to the
motor heat and muffler outlet, this can cause
posible serious injury.
Hold the trimmer with the right hand on the
rear handle and the left hand on the front “D“
handle. Keep a firm grip with both hands while
in operation. Trimmer should be held at a com-
fortable position with the rear handle about
hip height.
Always operate trim-
mer at full throttle.
Cut tall grass from the
top down.
This will prevent
grass from wrapping
around the driveshaft
housing and string
head which may cause
damage from over-
heating.
