7. Replace the chain/sprocket end cover by positioning
the cover onto the saw head. Fit the end cover knob by
inserting the bar stud into the bar stud hole. Tighten the
end cover knob, but leave the bar free to move for tension
adjustment (Fig. 11).
8. Remove all slack from the chain by turning the chain
tensioner ring clockwise until the chain seats snugly
against the bar with the drive links in the bar groove
(Fig. 12).
NOTE: The chain is correctly tensioned when there is no
sag on the underside of the guide bar; the chain is snug,
but can be rotated by hand without binding. For more
information on chain tensioning, see the maintenance
section beginning on pg. 17.
9. Raise the guide bar and tighten the end cover knob
securely.
Prepare to Work
Check the Machine

WARNING!
Before performing any checks,
adjustments, repairs or maintenance on the machine, make
sure the battery is not inserted in the compartment.
m
CAUTION!
The chain will continue to run for several
seconds after turning off the tool.
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 On/Off switch and the safety lock button
move freely without forcing and return automatically and
rapidly back to their neutral positions;
• Check that the On/Off switch remains locked until the
safety lock 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
1. Tension the chain by turning the chain tensioning ring
clockwise (Fig. 13). 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.
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. 14).
