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
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, guide bars with a sprocket at their tip must be lubricated weekly with a grease syringe to extend
the guide bar life.Using a grease syringe, lubricate weekly in the lubricating hole.
Turn the guide bar and check that the lubrication holes and chain groove are free from obstructions.
NOTE: A new chain tends to stretch, check chain
tension frequently and tension as required.
Chain Maintenance
CAUTION:
Disconnect from the power supply and make sure
the chain has stopped before you do any work on
the saw.
For smooth and fast cutting, chain needs to be main-
tained 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 remember:
How To Sharpen The Cutters
and to the same length, as fast cutting can be ob-
tained only when all cutters are uniform.
Wear gloves for protection. Properly tension the
chain prior to sharpening.Refer to”Chain Tension
the midpoint of the bar.

sure stroke towards the front corner of the tooth.
CHAIN TENSION AND
MAINTENANCE
Chain Tension
Stop the engine before setting the chain tension.
tight turn the tensioning wheel up or down to tension
the chain.A cold chain will be correctly tensioned
when there is no slack on the underside of the guide
bar the chain is snug, but it can be turned by hand
without binding.
the drive links hang out of the bar groove.
During normal saw operation the temperature of
the chain will increase. The drive links of a correctly
tensioned warm chain will hang approximately .050
in. (1.25mm) out of the bar groove. Be aware that
chain tensioned while warm, may be too tight upon
cooling. Check the “cold tension” before next use.
the risk of 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 service dealer sharpen chain.
NOTE: Inspect the drive sprocket for wear or dam-
age when replacing the chain. If signs of wear or
damage are present in the areas indicated, have the
