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 trimmer.
Important: The thickness of branches, which may be cut using this trimmer, is limited to up to approximately 5 mm. Never try to cut branches thicker than this,
as doing so may result in damage to the trimmer.
Adjusting the angle of the cutting blades (X)
(1) Clamp lever (2) Trimming mechanism
1. Stop the engine
2. Turn the bolt located on the top of the trimming mechanism counter clockwise to loosen it.
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.
