OPERATION

HOLDING THE STRING TRIMMER

WARNING:

Dress properly to reduce the risk of injury when operating this unit. Do not wear loose clothing or jewelry. Wear eye protection. Wear heavy, long pants, boots and well fitting gloves. Do not wear short pants, sandals or go barefoot.

•Hold the string trimmer as shown. See Figure 9. Right arm is slightly bent, the right hand holding the rear handle. Left arm is straight, the left hand holding the front handle. The unit should be slightly below waist level.

•The string head on your string trimmer should be parallel to the ground and should easily contact the material being cut without the operator having to bend over. A simple shaft adjustment accom- modates most user's heights.

USING THE STRING TRIMMER

ADVANCING LINE

Your string trimmer is equipped with a string head, which allows the operator to release more cutting line without stopping the motor. As the line becomes worn or frayed, additional line can be released by lightly tapping the string head on the ground while operating the string trimmer at full throttle. See Figure 10. For best results, tap the head on bare ground or hard soil. If line release is attempted in tall grass, the motor may overheat.

Fig. 10

Approximately 1 inch (25.4 mm) of cutting line is released each time the head is tapped on the ground.

Always keep the cutting line fully extended. If the string is worn too short you may not be able to ad- vance the string by tapping the head on the ground. If this occurs, stop the motor, remove the spool as described in the following section, feed the cutting line through the opening in spool housing and reassemble the spool to the string head.
