MAINTENANCE

CHAIN BRAKE

This machine is equipped with an automatic brake to stop the saw chain rotation upon kickback.  
The brake is automatically operated by inertial force, which acts on the weight fi tted inside the 
front guard.
The brake can also be operated manually when the front guard is pushed down to the guide bar.
To release the brake, pull up the front guard toward the front handle until a “click” sound is 
heard.

To confi rm brake operation:
With chainsaw stopped push brake handle forwards until a “click“ sound is heard. Ensure that 
the chainsaw will now not operate. Pull the brake handle backwards to release the brake.
When the brake engages during operation, immediately release the trigger to stop the chainsaw.

CHAIN SHARPENING

Working with a blunt chain causes the chain, guide bar and drive sprocket to wear and may lead 
to the chain breaking so it is important to keep the chain sharp.
It is advisable to have the chain sharpened by a specialist.

CHAIN LUBRICATION

Running the saw without chain lubrication will quickly damage the chain and guide bar.
Check the lubrication by switching on the saw and hold it with the guide bar and chain above 
some light coloured paper. A steadily increasing stain caused by oil spray indicates that the      
lubricating system is working correctly.

GUIDE BAR

Use a grease gun to apply a small amount of grease through the grease holes near the four 
rivets holding the nose sprocket on the guide bar.
The bottom edge of the bar is exposed to relatively heavy wear and so the bar should be turned 
top to bottom whenever the chain in sharpened and the groove in the bar and the oil holes 
cleaned.

DRIVE SPROCKET

If the teeth of the drive sprocket show any signs of wear, the sprocket should be replaced. In 
any case it should be changed with every second replacement of the chain.

CARBON BRUSHES

When the saw’s brushes are worn beyond a certain limit, a tripping device automatically stops 
the motor. The brushes must be replaced by a chainsaw specialist.
