A properly sharpened saw chain cuts through
wood effortlessly, even with very little pressure.
Never use a dull or damaged saw chain. A dull
saw chain cutter leads to increased physical
strain, increased vibration load, unsatisfactory
cutting results and increased wear.
For smooth and fast cutting, the chain needs
to be maintained properly. The chain requires
sharpening when the wood chips are small and
powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one
side. During maintenance of your chain, consider
the following:
- Improper filing angle of the side plate can
increase the risk of a severe kickback.
- Raker (depth gauge) clearance. Too low
increases the potential for kickback. Not low
enough decreases cutting ability.
- If cutter teeth have hit hard objects, such as
nails and stones, or have been abraded by
mud or sand on the wood, have the chain
sharpened by a qualified service technician.
NOTE:
Inspect the drive sprocket for wear or
damage when replacing the chain. If signs
of wear or damage are present in the areas
indicated, have the drive sprocket replaced by
qualified service technician.
GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear,
reverse it on the saw to distribute the wear for
maximum bar life. The bar should be cleaned
every day of use and checked for wear and
damage. Feathering or burring of the bar rails is
a normal process of bar wear. Such faults should
be smoothed with a file as soon as they occur.
A bar with any of the following faults should be
replaced.
- Wear inside the bar rails which permits the
chain to lay over sideways.
- Bent guide bar.
- Cracked or broken rails.
- Spread rails.
In addition, the guide bar has a sprocket at its tip.
The sprocket must be lubricated weekly with a
grease syringe to extend the guide bar life. Use a
grease syringe to lubricate weekly with chain oil
by means of the lubricating hole. Turn the guide
bar and check that the lubrication holes and
chain groove are free from impurities.
TRANSPORTING AND STORING
- Do not store or transport the chain saw
when it is running. Always remove the
battery pack before storing or transporting.
- Always place the guide bar sheath on
the guide bar and chain before storing or
transporting the chain saw. Use caution to
avoid the sharp teeth of the chain.
- Clean the chain saw thoroughly before
storing. Store the chain saw indoors, in a dry
place that is locked and/ or inaccessible to
children.
- Keep away from corrosive agents such as
garden chemicals and de-icing salts.
