No tools are required to attach the Line Trimmer to the power
head assembly.
1. Pull the spring pin up on the adapter of the power head
shaft assembly. (Picture 8)
2. Carefully fit the line trimmer drive shaft into the adapter,
making sure that the male spline of the inner drive shaft
engages into the female spline socket of the power head
shaft. (Picture 9)
3. When the drive shaft is properly aligned, the spring pin
will drop into the hole on the shaft of the line trimmer
attachment. (Picture 10) A click should be heard when
completed.
4. Insure two shaft parts are fully engaged by twisting them.
Full engagement will prevent shaft rotation.
5. Secure assembly by tightening the knob. (Picture 11)
6. Unit handles can be re-adjusted to the operator’s
preference by simply loosening the screws and sliding the
handles up or down the shaft.

Check the balance of the assembled unit. The handles and
shoulder harness have been assembled at the factory and set
according to the average size person. This can be adjusted to
the operator’s preference by simply loosening the screws and
sliding handles up or down the shaft. Re-tighten the screws.
Balancing the unit
1. With both hands on the handles, push lockout trigger
button with your thumb first, and then squeeze trigger.
Start cutting when spool rotates at full RPM.

2. Always remember that the tip of the line does the cutting.
You will not get better results by moving line deeply into
the cutting area.
3. Hold the cutting head of the unit off the ground, and use a
sweeping (left to right) motion. Try to control cutting
motion with the hip rather than placing the full workload
on the arm and hands.
4. The rate of the cutting motion depends on the material
being cut: heavy growth will require slower action.
5. Take precautions to avoid wire or dry long-stem plant
material from wrapping around the cutting head shaft. This
can stall the head. If repeated frequently, this can cause
damage of the unit.
