Attaching the Line Trimmer to the Power Head

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.

Balancing the unit

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.

Trimming techniques

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.

Adjusting the length of the line

Operator can increase the length of the line when it becomes short, without stopping the engine. In order to do this you have to lightly tap the head of the string trimmer on the bear ground or hard soil while running the engine at full throttle.
