10 ASSEMBLY
Always wear gloves when handling the bar and chain; these components are
sharp and may contain burrs.
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. 4-5)
▪ Remove the battery from the chain saw.
▪ Rotate the chain cover lock knob anti clockwise and remove knob and sleeve .
▪ Remove the chain cover.
▪ Lay out the new saw chain in a loop and straighten any kinks. The cutters should face in
the direction of chain rotation. 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.
▪ it 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 chain cover.
▪ Replace the sleeve and chain cover lock bolt; . Turn the knob clockwise to tighten the
drive 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 clockwise 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 and turn the chain tensioning wheel 1/2 turn clockwise.
Repeat this process until sag does not exist.
▪ Hold the tip of the guide bar up and tighten the chain cover lock bolt. 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 chain is too tight, it will not rotate. Loosen the chain cover lock knob
slightly and turn the chain tensioning wheel 1/4 turn anti clockwise. 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. 6)
▪ Before starting up your new chain saw, the container must be filled with chain saw oil.
(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.
▪ To top the saw up with lubricating oil unscrew the filler cap. Make sure that no dirt gets
into the oil container while filling up. The oil level can be checked through the gauge glass.
