Reinforcement chipped
Bar used improperly. Saw jammed in the cut.
Log slid over bar.
Running surface scored
Improper use caused extreme lateral
pressure on the running surface at the bar
nose. A common problem most often caused
by log slippage.
Cavities in bar
Impact of the chain behind the reinforced
area of the bar as a result of the insufficient
chain tension. Dull cutting teeth. Extreme
pressure applied to front area of the bar.
Sprocket
A damaged sprocket will ruin your chain. Replace a damaged sprocket immediately; the
cost is only ¼ that of a new chain. It is therefore uneconomical to run new chains on old sprockets.
Avoid the problems caused by damaged sprocket:
1. Check it each time you mount a new chain, and replace it if it shows signs of wear.
2. Always make sure that the chain tension is sufficient.
Maintaining the chain clean and sharpen.
Cutting without problems with the right sharpened chain.
A saw which was well sharpened pulls itself without problems and light pushing in the wood.
Do not work with a blunt or damaged chain. This leads to a high human exertion, not satisfying
result, and a high wear.
Cleaning and checking the chain - for cracks in the chain links or rivets.
Renew damaged and used chain parts and adjust them to the others and correct them.
Important!
Keep the following angles and dimensions. A chain with a wrong sharpening especially too low
depth limiter can lead to high kickback slope of the saw – danger of injury!
Choose sharpening tools which fit to the pitch of the chain – allowed pitches of the chain, see
„Technical Specification“.
The size for the pitch of the chain (e.g. 3/8“) is stamped in the area of the depth limiter of every
cutting tooth.
Do only use special chain files!
Other files do not fit in shape and cut
The assignment of the filing diameter does only work after the pitch of the chain.
Look at the table at the bottom of this chapter.
A = sharpening angle
B = front angle
