CARE AND MAINTENANCE
WARNING!
Keep all parts of the body
away from the chainsaw when the chainsaw
is operating. Before you start the chainsaw,
make sure the chainsaw is not contacting
anything.
A moment of inattention while operating
chainsaws may cause entanglement of your
clothing or body with the saw chain.
■ Use only a guide bar and saw chain as
listed in the Product Specications of this
manual.
■ Lay the saw chain into the groove of the bar
with the cutting edges of the chain pointing in
the rotational direction shown on the bar.
(Fig. 27)
■ Ensure that the guide bar tension disc is
adjusted to the outermost position away from
the bar; turn the disc counterclockwise if
required. (Figs. 31-32)
■ Lay the saw chain around the drive
sprocket, and lay the guide bar against the
WARNING!
Always use a saw chain
designated as “low-kickback” or a saw chain
which meets the low-kickback requirements!
A standard saw chain (a chain which does
not have the kickback reducing guard links)
should only be used by an experienced
professional operator! Nevertheless, a low-
kickback saw chain does not completely
eliminated kickback! A low-kickback or “safety”
chain should never be regarded as complete
protection against injury! Therefore always
use a low-kickback saw chain in conjunction
with other kickback protection devices such
as the front hand guard!
DANGER!
Never start the motor
before installing the guide bar, chain, chain
cover, and chain cover lock knob. Without
all these parts in place, the clutch can y off
or explode, exposing the user to possible
serious injury.
REPLACING THE GUIDE BAR AND CHAIN
See Figures 26-39, page viii-x
saw body so that the support bolt protrudes
through the hole in the guide bar tension disc.
(Figs. 33-34)
■ Replace the chain cover and slightly tighten
the lock knob. (Fig. 35)
■ Do not tighten the lock knob completely;
saw chain tensioning is required rst.
■ Release the tip of the guide bar, and turn
the chain tensioning knob 1/2 turn clockwise.
(Fig. 35)
■ Hold the tip of the guide bar up and fully
tighten the chain cover lock knob.
The chain is correctly tensioned when there
is no sag on the underside of the guide bar,
and when the chain is snug it can be turned
by hand without binding.
NOTE:
If chain is too tight, it will not rotate.
Loosen the chain cover lock knob slightly,
and turn the chain tensioning knob 1/4 turn
counterclockwise. Lift the tip of the guide
bar up, and retighten the chain cover lock
knob. Ensure that the chain will rotate without
binding.
SAW CHAIN TENSIONING
■ Always check the saw chain tension before
use and regularly during use (approximately
every ve cuts).
■ Upon initial operation, new chains can
lengthen considerably. This is normal during
the break-in period and the interval between
future adjustments will lengthen quickly.
■ To tension chain, rst set the the chainsaw
on a suitable at surface.
■ Turn the tensioning knob until the chain “tie
straps” are just touching the bottom edge of
the guide bar. (Fig. 28)
WARNING!
Never touch or adjust the
chain while the motor is running. The saw
chain is very sharp. Always wear protective
gloves when performing maintenance
involving the chain.
