SAW CHAIN 

Warning

It is very important for smooth and safe operation to always keep
the cutters sharp. 

Your cutters need to be sharpened when: 

• Sawdust becomes powder-like. 
• You need extra force to saw in. 
• The cut does not go straight. 
• Vibration increases. 
• Fuel consumption increases. 

Cutter setting standards: 

Warning

Be sure to wear safety gloves. 

Before filing: 

• Make sure the saw chain is held securely. 
• Make sure the engine is stopped. 
• Use a round file of proper size for your chain. 

Chain type: 21VB 

File size: 3/16in (4.76mm) 

Place your file on the cutter and push straight forward. Keep the file
position (F30).  

After every cutter has been set, check the depth gauge and file it to
the proper level (F31).  

Warning

Be sure to round off the front edge to reduce the chance of
kickback or tie-strap breakage.
