2. The throttle lever to be pressed on 1/4 position.
(Fig.10)
CAUTION: Do not move the throttle lever to max
throttle. It will suddenly spin the blade at high
speed.
3. Set the choke lever to closed position.(Fig.11)
4. Pull the recoil starter briskly. When you hear the
engine fires, move the choke lever back to open
position. Then pull the recoil starter briskly until the
engine starts and runs.
5. After starting the engine, allow it about 2~3 min-
utes to warm up at an idle speed 2800~3200rpm
before subjecting it to any load.
CAUTION: Blade may run and flexible shaft may
swing as starting the engine. Don’t let the blade
touch anything when starting the engine.
6. Idle speed adjustment
When the idle speed is too high or too low, adjust
it with the idle speed adjusting screw. If the idle
speed is too high, turn the adjusting screw counter-
clockwise. If the idle speed is too low, turn the
screw clockwise.(Fig.12)
4.3. Installing the blade:
1. Before installing a blade, you must check if there
are signs of damage to the blade. Replace the
blade that is cracked, bent or chipped.
2. After installing the blade, be sure to align the hole
in the blade with the shoulder on cutter holder.
Turn the blade briskly to check if the blade turns
deflective.
3. Make sure you install the blade with cutting edges
and the arrow on the blade in the direction of rota-
tion. Never install it reversed.
4. Make sure the blade has been properly installed by
running the blade with no load for a minute before
cutting. Do not operate the engine over 6000rpm.
5. The type of blade must be matched to the type and
size of cut.
6. Never thrust the blade into the objects when cut-
ting. You must cut the objects at a moderate speed.
7. Do not stop the machine while cutting. It may
cause danger and blade damage.
