Use  only  special  saw  chain  sharpening  files.  Other  files  have  the  wrong  shape  and 
cut.Select file diameter according to chain pitch. Ensure to observe certain angles when 
resharpening the chain cutter.

 Cutting Shapes: Micro=Semi-chisel

 The specified angles A and B are obtained automatically if the recommended files or 
sharpening  tools  and  correct  settings  are  used.  The  angles  must  be  the  same  on  all 
cutters. If the angles are uneven: Chain will run roughly, not in a straight line, wear quickly 
and finally break. As these requirements can be met only after sufficient and constant 
practice: 

Ÿ

Use a file holder :A file holder must be used for manual resharpening . The correct 
filing angles are marked on the file holder.

WARNING

  It  is  absolutely  essential  to  comply  with  the  angles  and 
dimensions  specied  below.  If  the  saw  chain  is  incorrectly 
sharpened – and in particular if the depth gauge is set too low – 
there  is  an  increased  risk  of  kickback,  with  resulting  risk  of 
injury.

ENGINE MANAGEMENT

Cleaning the Air Filter

Ÿ

Accumulated  dust  in  the  air  filter  will  reduce  engine  efficiency,  increase  fuel 
consumption and allow abrasive particles to pass into the engine. Remove the air filter 
as often as necessary to maintain a clean condition.

Ÿ

Light surface dust can readily be removed by tapping the filter. Heavy deposits should 
be washed out in suitable solvent. 

Ÿ

Remove filter cover by loosening air filter cover knob.

Spark Plug

 If engine is down on power, difficult to start or runs poorly at idling speed, first check the 
spark plug. Fit a new spark plug after approximately every 100 operating hours or earlier 
if the electrodes are badly eroded. Wrong fuel mix (too much engine oil in the gasoline), a 
dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the 
condition of the spark plug. These factors cause deposits to form on the insulator nose 
which may result in trouble in operation.

Removing the Spark Plug

Ÿ

Move the slide switch to STOP. 

Ÿ

Pull off the spark plug boot.

Ÿ

Unscrew the spark plug.
