NOTE: If the chain is too tight, it will not rotate. Loosen the
end cover nut slightly and turn the chain tensioner 1/4 turn
counterclockwise. Lift the tip of the guide bar up and retighten
the end cover nut. Ensure that the chain can be rotated by
hand without binding.
NOTE:
A new chain tends to stretch; check the chain tension
frequently, and adjust tension as required.
Preparing To Work
Checking the Machine
m
WARNING!
Before performing any checks,
adjustments, repairs or maintenance on the machine, make
sure the battery is not inserted in the compartment.
Before starting work please:
• Check that all the screws on the machine and the guide
bar are tightly fastened;
• Check that the chain is tensioned correctly, sharp and
there are no signs of any damage;
• Check that hand grips and protection devices are clean
and dry, correctly mounted and securely fastened to the
machine;
• Check that the chain brake is working efficiently;
• Check that the trigger switch and the safety button move
freely without forcing and return automatically and rapidly
back to their neutral positions;
• Check that the trigger switch remains locked until the
safety button is pressed;
• Make sure the cooling air vents are not clogged with
sawdust or debris;
• Check that the chain’s oil level is not below the "MIN"
level mark; if necessary, top up the oil to 1 cm from the
rim of the filler.
NOTE:
You must fill the chain oil tank with bar and chain
oil before using your chain saw.
Adjusting the Chain Tension
m
WARNING!
Before performing any checks,
adjustments, repairs or maintenance on the machine, make
sure the battery is not inserted in its housing.
m
CAUTION!
The chain will continue to run for several
seconds after turning off the tool.
1.
Loosen the end cover nut until it is hand-tight. Use the
flat-tip blade screwdriver to turn the chain tensioner
screw clockwise 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 (Fig. 10).
2. The tension is correct when the drive links on the chain do
not slip out of the chain guide on the bar when the chain
is pulled up from the middle of the bar (Fig. 11).
Loosen the brake by pressing both the switch and the safety
button. Using a screwdriver, run the chain along the guides to
check that it moves smoothly.
