How to Replace the Saw
1a Pull the chain-brake back and ensure that it has been released (the chain cover can only be
removed with the chain-brake disengaged)
.
1b Then remove the securing nuts and the chain cover
1c Fit the chain around the bar ensuring that the direction of the chain is as depicted in the
picture on the bar. Fit the chain on the sprocket. Adjust the position of chain tensioner so the
tensioner pin locates in the hole (A) on the bar.
5. Adjust the tension to ensure that there is not too much slack in the chain. Make sure the
tensioner pin is located in the assembly hole on the bar. Pay attention to the correct direction of
the saw chain. Compare with the picture near the chain sprocket and the picture on the bar.
6. Fit the chain cover to the power unit.While lifting tip of guide bar, tighten bar knob securely
(clockwise).
Hand tighten only!
7. While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until
the chain engages in the bar channel.

When tensioned correctly it should be possible to pull one full chain link free of the bar channel
with ease see image (1d).
8. Tighten the nuts securely finger tight. Then check the chain for smooth rotation and proper
tension while moving it by hand. If necessary, loosen the chain cover.

NOTE!
It is very important for smooth and safe operation to cut with a sharp chain. The chain
needs replacing when:
1. Sawdust becomes powder-like.
2. Cutting requires extra force.
3. The chainsaw does not cut straight and clean.
4. Vibration increases.
5. Fuel consumption increases.
NOTE!
A new chain will expand its length during the first period of use. Check and re-adjust the
tension frequently as a loose chain can easily derail or cause rapid wear of itself and the chain
bar.
CAUTION!
If the saw chain is TOO LOOSE or TOO TAUT, the Vdrive wheel, chain bar, chain and
crank shaft bearing will suffer premature wear. FIG 8 shows the correct tension A (when cold)
and tension B (when warm). FIG C shows a chain that is too loose.
