WARNING
KICKBACK DANGER
Do not attempt a boring cut if you are not properly
trained. A boring cut involves the use of the nose of
the guide bar and can result in kickback. (Fig. 33)
If the saw gets stuck
Stop the engine. Raise the log or change its position,
using a thick branch or pole as a lever. Do not try to pull
the saw free. If you do, you can deform the handle or be
injured by the saw chain if the saw is suddenly released.

In the carburetor, fuel is mixed with air. When the engine
is test run at the factory, the carburetor is 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. 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 metabo HPT Authorized Service
Centers.
WARNING
When the engine is idling the cutting attachment
must under no circumstances rotate.
NOTE
Do not touch the High speed adjustment (H) and the
Low speed adjustment (L).
Those are only for metabo HPT Authorized Service
Centers.
If you rotate them, it will cause a serious damage to
the machine.
Air fi lter (Fig. 35)
The air fi lter (39) must be cleaned from dust and dirt in
order to avoid:
○ Carburetor malfunctions.
○ Starting problems.
○ Engine power reduction.
○ Unnecessary wear on the engine parts.
○ Abnormal fuel consumption.
Clean the air filter daily or more often if working in
exceptionally dusty areas.
Remove the air fi lter cover (40) and the fi lter (39).
Rinse them in warm soap suds. Check that the fi lter is
dry before reassembly. An air fi lter that has been used
for some time cannot be cleaned completely. Therefore,
it must regularly be replaced with a new one. A damaged
fi lter must always be replaced.
