Run the engine while adjusting the idling.
(1) If the engine stops during idling
Start the engine, and slowly turn the idle speed
adjustment screw (T) in a clockwise direction
until it is in a position at which the engine rotates
smoothly. At that time, ensure that the cutting
attachment is not spinning.
(2) If the cutting attachment rotates during idling
Slowly turn the idle speed adjustment screw (T)
in a counter-clockwise direction until it is in a
position at which the cutting attachment does not
rotate. At that time, ensure that the rotation of the
engine is smooth.
WARNING
If the cutting attachment still rotates after
adjustment of the idle speed adjustment
screw (T), immediately stop the engine
and cease use, then contact the nearest
metabo HPT Authorized Service Center.
Air fi lter (Fig. 17)
The air fi lter (14) 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 fi lter daily or more often if working in
exceptionally dusty areas.
Cleaning the air fi lter
Open the air fi lter cover and remove the air fi lter
(14). Clean it.
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.
NOTE
To put the air fi lter cover back into place, hook it
on the upper tabs and then attach it.

Fuel fi lter (Fig. 18)
Remove the fuel fi lter (15) from the fuel tank, and
replace it if it is dirty.
NOTE
A blocked fuel fi lter (15) can prevent the supply of
fuel and cause a rotation malfunction of the engine.

Spark plug (Fig. 19)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting diffi culties. If the engine is low on power,
diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rst. If the spark plug is dirty,
clean it and check the electrode gap. Re-adjust
if necessary. The correct gap is 0.024˝ (0.6 mm).
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.
0.024˝
(0.6 mm)
NOTE
In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this
machine was originally equipped with resistor
spark plug, use same type of spark plug for
replacement.
