MAINTENANCE

 WARNING

Use only original manufacturer's replacement parts 
and accessories. Failure to do so may cause poor 
performance, contribute to possible injury, and will void 
your warranty.

■

The cutting attachment must not rotate in idle mode. 
If this requirement is not satisfied, the clutch has to be 
adjusted or the product needs an urgent maintenance 
by a qualified technician.

■

You may make adjustments and repairs described 
in this user manual. For other repairs, have the unit 
serviced by an authorized service agent.

■

Consequences of improper maintenance may 
include excess carbon deposits resulting in loss of 
performance and discharge of black oily residue 
dripping from the silencer.

■

Make sure the cutting attachment guards, harness and 
handles are properly and securely attached to avoid 
the risk of personal injury.

STRING REPLACEMENT

See 

fi

 gure 8.

■

Ensure the ignition switch is in the “off” position.

■

Use a 2.4 mm diameter monofilament string.

■

Cut one piece of string approximately 6 m in length.

■

Rotate the knob on the string head until the line on 
knob aligns with the arrows on the top of string head.

■

Insert one end of the string into the eyelet located on 
the side of the string head and push until string comes 
out through eyelet on the other side. Continue to push 
string through the string head until the middle section 
of the string is inside the string head and string outside 
the string head is evenly divided on each side.

■

Rotate the knob on the string head clockwise to wind 
the string.

■

Wind the string until approximately 20 cm remains 
protruding from the string head.

BLADE PROTECTOR

See 

fi

 gure 18.

Always place the blade protector on the blade when the 
product is not in use. The blade protector has clips round 
the edges to snap over the blade and keep it in place. 
Wear gloves and be cautious when handling the blade.

NOTE

: Always remove the blade protector before using 

the product. If not removed, the blade protector could 
become a thrown object as the blade begins to turn.

CLEANING THE EXHAUST PORT AND SILENCER

Depending on the type of fuel used, the type and amount 
of oil used, and/or your operating conditions, the exhaust 
port and silencer may become blocked with carbon 
deposits. If you notice a power loss with your petrol-
powered tool, a quali

fi

 ed service technician will need to 

remove these deposits to restore performance.

CLEANING THE AIR FILTER

See 

fi

 gure 19.

■

Ensure the ignition switch is in the “off” position.

■

Remove the air filter knob and air filter cover.

■

Remove the air filter and clean it with warm soapy 
water. 

■

Rinse, and let the air filter dry completely.

■

Replace the air filter. 

NOTE:

 If damaged, replace immediately.

■

Replace the air filter cover.

■

Tighten the air filter knob.

NOTE:

 The air filter should be replaced annually for 

the best performance.

CHECKING THE FUEL CAP

 WARNING

A leaking fuel cap is a 

fi

 re hazard and must be replaced 

immediately.

The fuel cap contains a non-serviceable 

fi

 lter and a 

check valve. A clogged fuel 

fi

 lter will cause poor engine 

performance. If performance improves when the fuel cap 
is loosened, the check valve may be faulty or the 

fi

 lter may 

be clogged. Replace fuel cap if required.

SPARK PLUG

This engine uses an L8RTF/NHSP LD, or L8RTF/BOSCH 
spark plug or equivalent with 0.5 mm electrode gap. Use 
an exact replacement.

CAUTION

Be careful not to cross-thread the spark plug. Cross-
threading will damage the engine.
