8. Operation
(LRT-EX only)
WARNING
This product is equipped with extremely sharp blades, and when used improperly these blades can be extremely dangerous, and improper handling can cause accidents which may in turn lead to serious injury or death. For this reason, you should always be careful to follow the following instructions when using your trimmer.
•Never hold the trimmer in a way in which the blades are pointed towards someone else.
•Never allow the blades to come into proximity with your body while the engine of the trimmer is in operation.
•Always be sure to turn off the engine before changing the angle of the blades, removing branches which have become stuck in the blades, or at any other time when coming into close proximity with the blades.
•Always wear work gloves made of leather or some other sturdy material when using the trimmer.
•Always place the blade cover provided with the trimmer over the blades when not in use.
•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.

■CHECKING OIL SUPPLY
After starting the engine, run the chain at medium speed and see if chain oil is scattered off as shown in the figure. (OP1)
(1) Chain oil
NOTE
The oil reservoir has a capacity sufficient to provide about 40 minutes of cutting time (when set to deliver the minimum flow rate, or about as long as you'll get from a tank of fuel). Be sure to refill the oil tank every time when refueling the saw.
■ADJUSTING OIL FLOW RATE
WARNING
Never fill the oil reservoir nor adjust the oiler with the engine running.
IMPORTANT
An increase in 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.
LRT-EX OP1
IMPORTANT
The thickness of branches which may be cut using this trimmer is limited to up to approximately 3/16" (5mm).
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 (OP1)
1.Stop the engine.
2.Turn the bolt located on the top of the trimming mechanism
3.Adjust the angle of the blades to the desired angle, and then fix the bolt firmly back into place.
PS-EX OP2
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 flow is often desirable when cutting things like hardwood or wood with a lot of pitch.
Adjust the pump as follows:
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. (OP2)
