the rope, or remove the spark plug and dry it.
Stopping the engine
1. Release the throttle lever and run the engine for half a minute.
2. Shift the stop switch to the STOP position.
Important: Except for an emergency, avoid stopping the engine while pulling the throttle lever.
When it doesn't stop at the stop switch, move the choke level to the closed position.
Adjusting the throttle cable (R)
The normal play is 1 or 2mm when measured at the carburettor side end. Readjust the cable adjuster as required
(1) Cable adjuster
Adjusting the idling speed (S)
(1) Idle adjusting screw
1. When the engine tends to stop frequently at idling mode, turn the adjusting screw clockwise.
2. When the cutting head keeps rotating after releasing the trigger, turn the adjusting screw counter-clockwise.
Note: Warm up the engine before adjusting the idling speed.
Warning: The cutting head will start rotating upon the engine starts.
Feed fuel into the fuel tank and tighten the cap securely (T), (U).
(1) Fuel (2) Chain oil
2. Rest the unit on a flat, firm place. Keep the cutting head off the ground and clear of surrounding objects, as it will start rotating upon starting of the engine.
3. Push the primer several times until overflown fuel comes out in the transparent tube.
4. Move the choke lever to the closed position | \ |.
Checking oil supply (Y)
(1) Chain oil
After starting the engine, run the chain at medium speed and see if chain oil has scattered off, as shown in the figure.
Note: The oil reservoir has a capacity sufficient to provide about 40 minutes of cutting time (when set to deliver the mini mum flow rate, or about as long as you
get from a tank of fuel). Be sure to refill the oil tank every time when refu elling the saw.
Adjusting oil flow rate
Warning: Never fill the oil reservoir nor adjust the oiler with the engine running.
Important: An increase in the bar oil flow rate will speed oil consumption, requiring more frequent checks on the oil reservoir.
To ensure sufficient lubrication, it may be necessary to check the oil level more frequently than at fuel tank refills.
The guide bar and chain are lubricated automatically by a pump that operates whenever the chain rotates. The pump is set at the factory to deliver a minimum
flow rate, but it can be adjusted in the field. A temporary increase in oil f low is often desirable when cutting things like hard wood or wood with a lot of pitch.
Adjust the pump as follows (Z):
1. Stop the engine and make sure the stop switch is in the OFF position.
2. Place the unit on its side with the oil reservoir up.
(1) Oil tank, (2) Chain cover
The oil flow adjusting screw must be pressed in slightly in order to turn. Failure to do so could damage the pump and screw.
3. With a screwdriver, push in on the oil flow rate adjust ing screw and turn in the desired direction (there are three incremental settings):
(a) Clockwise-decrease lubrication
(b) Counter clockwise-increase lubrication
(c) Middle
WARNING: Always wear work gloves made of leather or some other sturdy material when using the pole-saw. Falling branches may fall onto the face or into the
eyes, resulting in injuries, scratches, and cuts, and for this reason you should always be sure to wear a helmet and face protector when using your pole-saw.
