Never touch or adjust the chain while the motor is running. The saw chain is
very sharp; always wear protective gloves when performing maintenance to
the chain to avoid possible serious lacerations.
10.1 To assemble the chain and bar (Fig. A & D)
▪ Remove the battery from the chain saw.
▪ Rotate the sprocket cover knob (4) anti clockwise and remove the knob and the cover (3) .
▪ Lay out the new saw chain in a loop and straighten any kinks. The cutters should face in
the direction of chain rotation (15) which is marked above the sprocket (16). If they face
backwards, turn the loop over.
▪ Place the chain drive links into the bar groove as shown.
▪ Position the chain so there is a loop at the back of the bar.
▪ Hold the chain in position on the bar and place the loop around the sprocket (16).
▪ Fit the bar flush against the mounting surface so that the bar studs are in the long slot of
the bar.
NOTE: When placing the bar on the bar studs, ensure that the adjusting pin
is in the chain tension pin hole.
▪ Replace the sprocket cover (3) .
▪ Replace the sprocket cover knob (4). Turn the knob clockwise to tighten the sprocket
cover. The bar should still be free to move for tension adjustment.
▪ Remove all slack from the chain by turning the chain tensioning wheel (17) down until the
chain seats snugly against the bar with the drive links in the bar groove.
▪ Lift the tip of the guide bar up to check for sag.
▪ Release the tip of the guide bar turn the chain tensioning wheel (17) 1/2 turn down.
Repeat this process until sag does not exist.
▪ Hold the tip of the guide bar up and tighten the sprocket cover knob. The chain is correctly
tensioned when there is no sag on the underside of the guide bar, the chain is snug, but it
can be turned by hand without binding.
NOTE: If the chain is too tight, it will not rotate. Loosen the sprocket cover
lock knob slightly, turn the chain tensioning wheel 1/4 turn up. Lift the tip of
the guide bar up and retighten the chain cover lock knob. Ensure that the
chain will rotate without binding.
10.2 Lubricating oil for the saw chain (Fig. D)
▪ Before starting up your new chain saw, the chain has to be lubricated manually. (Available
in our product range: POWOIL003 - 1L & POWOIL006 - 5L)
▪ It allows operating the chain saw at ambient temperatures down to as low as -15°C.
▪ Never use waste oil for lubricating the saw chain.
1. Switch off the saw and remove the battery.
2. Place the saw on a level surface.
3. Clean the guide bar and chain with a soft brush and solvent.
4. Apply oil in area (a) between the guide bar an chain.(FIG. D)
5. Refit the battery and run the saw until the oil is evenly distributed over the chain.
