General Safety
Instructions
Work Safely
Trimmers and brushcutters run at very
high speeds and can do serious damage
or injury if they are misused or abused.
Never allow a person without training or
instruction to operate your machine.
Stay Alert
You must be physically and mentally fit to
operate this machine safely.
Be Aware of the working Environment
Avoid long-term operation in very
hot or very cold weather. Make sure bystanders or observers
outside the 15 meters “danger zone”
wear eye protection.
Reduce the risk of bystanders
being struck by ying debris.
Make sure no one is within
15 meters- that’s about 16 paces-
of an operating attachment.

If contact is made with a hard object, stop the
engine and inspect the cutting attachment for
damage.
Be extremely careful
of slippery terrain,

Before Assembling
the Outer Tube
1. Using the hex wrench, loosen the
stopper bolt to the end.
2. Loosen the joint bolt. Do not lose the
shim washer.
Assembly of the
Outer Tube
T300
1. Slip the outer tube into the joint until
the tube bottoms. The outer tube or
gear case shaft may have to be rotated
slightly for the splines on the main
shaft to fully engage to the engine.
2. Place the D-shaped shim washer with
its flat side up in the gap of the joint.
Then, tighten the joint bolt securely
using the hex wrench.
3. Loosen the screw which tightens the
throttle lever to the outer tube. Shift the
throttle lever toward the blade.
4. Put the throttle cable into the tube.
Push throttle cable through hole in rear
grip.
5. Set the throttle cable onto the throttle
lever. Use the wrench so that the wire
edge goes into the slot of the throttle
lever securely.
NOTE:
Make sure that the throttle cable is built
into the cable guide of the throttle lever.
6. Shift the throttle lever back to original
position, pulling the earth cord and
throttle cable and tighten the screw
securely.
7. Remove the bolt tightening the cylinder
cover.
8. Put the bolt through the hole of the earth
cord terminal and tighten the bolt.
C300
1. Slip the outer tube into the joint until
the tube bottoms (up to the insert
label). The outer tube or gear case
shaft may have to be rotated slightly
for the splines on the main shaft to
fully engage to the engine.
2. Locate the outer tube so that the stop
per bolt can go into the stopper hole.
Using the hex wrench, tighten the
stopper bolt securely.
3. Place the D-shaped shim washer with
its flat side up in the gap of the joint.
Then, tighten the joint bolt securely
using the hex wrench.
CAUTION!
DO NOT REMOVE THE SHIM WASHER!
The shim washer prevents overtighten-
ing of the outer tube joint. Overtighten-
ing the outer tube joint could damage
the outer tube assembly.
4. Loosen the stopper bolt of the throttle
grip. Remove the stopper bolt and nut.
5. Fully loosen the clamp bolt of the
throttle grip.
6. Slip the right-side handlebar into the
throttle grip. Locate the throttle grip
so that the stopper bolt can pass
through the stopper hole. Securely
tighten the stopper bolt and nut.
7. Securely tighten the clamp bolt.
