CHAIN SAW SAFETY PRECAUTIONS
■
Extension Cord. When an extension cord is used
make sure:
(a) That pins on the plug of the extension cord are the
same in number, size and shape as those of the
plug on the chain saw.
(b) That extension cord is properly wired and in good
electrical condition.
(c) That the wire size is large enough for the AC
ampere rating of the chain saw.
SAVE THESE INSTRUCTIONS.

BEFORE OPERATION
CHAIN AND BAR ASSEMBLY (Fig. 1 - 3)
■
Ensure the saw is unplugged from the power supply
before starting disassembly operations.
■
Unscrew the knob and remove sprocket cover (5)
to expose sprocket.
■
Insert the guide bar groove through the two guide pin.
Mount the saw chain on the guide bar with the cutters
facing forward on the top of the bar. Holding the chain
snugly on the guide bar with one hand, position the
loop end of the chain over the sprocket.
■
Secure sprocket cover by tightening the knob (11).
SAW CHAIN TENSIONING (Fig. 4 - 5)
■
Ensure that the chain saw is unplugged and the chain
is inside the guide groove of the chain bar!
■
Using a crosshead screwdriver, turn the chain
tensioning knob clockwise until the saw chain is
correctly tensioned. While the knob is being tightened,
the chain bar must then be pushed upwards.
Check chain tension again. Do not tension the chain
too tightly.
IMPORTANT
When cold, it should be possible to lift the chain (3)
in the middle of the chain bar approx. 4-5 mm.
Tighten the chain tensioning knob well.
IMPORTANT
When warm, the saw chain will expand and
slacken and there is a danger of jumping off the
rail altogether. Re-tension if necessary. If the
chain is re-tensioned when hot, it must be
loosened again when the sawing work has been
completed. Otherwise, the contraction which
takes place as the chain cools would result in
excessively high tension. A new saw chain
requires a running-in-period of approx. 5 minutes.
Chain lubrication is very important at this stage.
IMPORTANT
The tension of the saw chain will affect its
performance and life. When used for the first time,
the tension can easily be set. However,
a new saw chain will stretch and should therefore
be rechecked after a little use. When checking,
be sure to disconnect the tool from the power
supply first.
■
After adjusting the tension of the saw chain, then secure
the sprocket cover by tightening the knob (Fig. 5).
AUTOMATIC OILING OF SAW CHAIN (Fig. 6)
In order to minimize friction with the guide bar, the saw
chain requires lubrication while in operation. This chain
saw is equipped with in-built auto oiling system which
automatically supplies oil to the saw chain.
Never use the saw when the oil gauge (8) is below the
“minimum” mark.
■
Minimum- When only approx.5 mm of oil is visible at
the lower rim if the oil gauge, the tank must be refilled.
■
Maximum - Refill until the window is full.
