stable surface, put the bar and chain onto the bar mounting
studs (12), ensuring the chain is around the drive sprocket (13).
Ensure that the cutters are pointing in the same direction as the
embossed graphic (13a) above and below the drive sprocket
(13).
•
(Fig. C3) Before fitting the chain cover check that the cam (17) is
in the correct position. The flat section of the metal cam should
be visible through the opening in the chain cover. If necessary,
press and turn the control knob (4) clockwise to rotate the cam
into the correct position.
•
(Fig. C4) Fit the chain cover by locating the bolt and using the
control knob (4) to tighten the chain cover finger tight. To tension
the chain, loosen the control knob (4) one full turn, press in
firmly and rotate clockwise. As the bar moves forward ensure
the chain links feed into the guide bar. When the control knob
stops rotating, apply further light pressure. Do not over-
tension. Allow the control knob to spring back to the "out"
position and rotate further clockwise to tighten the guide bar.
Apply moderate pressure to tighten. Replace the cover screw.
•
(Fig. C5/C6) Check the chain tension by placing the saw on a
firm surface. The tension is correct when the chain snaps back
after being pulled 1/8" (3mm) away from the chain bar with light
force from the middle finger and thumb. There should be no
"sag" between the guide bar and chain on the underside as
shown in Fig.C5. Fig C6 illustrates a sagging improperly
tensioned chain.
Note: Do not over-tension the chain as this will lead to excessive wear
and will reduce the life of the bar and chain.
Note: When the chain is new check the tension frequently (after
disconnecting from power supply) during the first 2 hours of use as a
new chain stretches slightly.

Oiling (Fig. D)
•
(Fig. D) Fill the reservoir via the oil filler cap (8) with standar
chain saw oil. If chain saw oil is not available SAE#30 motor o
can be substituted. Note: For temperatures below 30°F, us
SAE#10 oil. For temperatures above 75°F, use SAE#40 o
The level of oil is checked through the oil level indicator slot (7
Periodically switch off and check the oil in the indicator; if it

less than a quarter full, disconnect your chain saw from th
power supply and refill with the correct oil.
Auto-Stop Chain Braking System (Fig. E)
Your chain saw is fitted with an auto-stop chain braking system wh
will stop the chain within a fraction of a second each time you relea
the rear trigger, or if kickback should occur. This system should
tested before every use.
How to set your auto stop hand guard

•(Fig. E1) Pull the front guard (9) back into the "set"
position .Your chain saw is now ready to use.
How the anti-kickback chain braking system works
In the event of kickback, your left hand comes in contact with the fro
guard, pushing it forward and stops your chain saw within a f
fractions of a second.
How the inertia activated chain braking system works
The brake is activated when the front hand guard is pushed forwa
either manually, by the back of the user's hand or by its own weig
The advantage of the inertia brake is that it is activated by a seve
kickback, eg. when the chain hits metal, even if the user's hand do
not contact the hand guard, ie. when the saw is in the felling positio
