IMPORTANT NOTES:
•
Avoid raw fuel (fuel with no oil): this will cause severe damage to the internal engine
parts of the unit very quickly.
•
Avoid fuel with alcohol content: this will cause rapid deterioration of rubber and plastic
parts, plus it will disrupt engine lubrication.
•
Avoid fuel for 4-cycle engines: this can cause spark plug foulage, exhaust port blockage
or piston ring seizure.
•
Avoid using mixed fuels that have been left unused for extended periods of time, as this
may clog the carburettor and result in the engine failing to operate.
Chain Oil
Use motor oil SAE #10W-30 all year round, or SAE 30~ #40 in summer and SAE #20 in winter.
Starting the Engine
It is very dangerous to run a chainsaw that has any broken or missing parts. Before
starting the engine, make sure that all parts, including the bar and chain, are installed properly.
1. Fill fuel and chain oil tanks respectively, and tighten the caps securely.
2. Put the switch to "I" position.
3. While holding the throttle lever together with the throttle interlock, push in the side
throttle lock button and release the throttle lever to hold it at the starting position.
NOTE: when restarting immediately after stopping the engine, set the choke knob to the
first-stage position.
NOTE: Once the choke knob has been pulled out, it will not return automatically to the
operating position. Do not push it down. To return it, pull the throttle lever out.
