(LRT-EX only)
WARNING
This product is equipped with extremely sharp blades,
and when used improperly these blades can be ex-
tremely dangerous and improper handling can cause
accidents, which may in turn lead to serious injury
or death. For this reason, you should always be care-
ful 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 opera-
tion.
• Always be sure to turn off the engine before chang-
ing 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 trim-
mer 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 trim-
mer.
IMPORTANT
The thickness of branches, which may be cut using this
trimmer, is limited to up to approximately 3/16" (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
(1) Clamp lever
(2) Transmission
1. Stop the engine.
2. Turn the bolt located on the top of the transmission
counter-clockwise to loosen it.

Checking oil supply
After starting the engine, run the chain at medium speed
and see if chain oil has scattered off, as shown in the
figure.
(1) Chain oil
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’ll 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 bar oil flow rate will speed oil consump-
tion, 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 flow is often desirable when cutting things like hard-
wood or wood with a lot of pitch.
