MAINTENANCE AND REPAIRS
Maintaining the chain clean and sharpened
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, look „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 table at the bottom of this chapter.
The angles at the cutting tooth have to be kept at the next sharpening.
