Take care that the chain does not come into contact with the ground or foreign materials other than wood When sawing do not put pressure on the chain but allow the chain to bite through the wood while applying leverage on the area near the bar spikes When cutting thick branches or trunks reposition the bar spikes at a lower point to avoid strain and kickback during operation To do this pull the saw toward you slightly to loosen the clutches of the bar spikes and reposition lower in the material It is not necessary to completely remove all of the chainsaw bar from the wood The best results are obtained when the cutting speed of the chain is maintained at its top speed Attention should be paid when coming to the end of the cutting stroke sometimes the weight changes unexpectedly There is a risk of an accident to your legs and feet Do not remove the chainsaw from the wood when the chain is rotating Always wear a hard hat with visor to protect your head from falling branches The chain saw can only be used to fell trees smaller in diameter than the length of the guide bar Secure work area ensure no persons or animals are in the vicinity of the falling tree Never attempt to free a jammed saw with the motor running Use tree wedges to free chain and guide bar a The tree felling When cutting and felling operations are being performed by two or more persons at the same time the felling operations should be separated from the cu
