OPERATION

 

WARNING: 

Always wear the eye protection. 

Never lean over the trimmer head. Rocks or 

debris can ricochet or be thrown into eyes and face 

and cause blindness or other serious injury. When 

operating unit, check for the following:

Wear eye protection and heavy clothing. Hold front 

handle with one hand and auxiliary handle with the 

other hand. Keep unit below waist level. Work only 

from your right to your left to ensure debris is thrown 

away from you. Without bending over, keep line 

near and parallel to the ground (perpendicular when 

edging) and not crowded into material being cut.

 

WARNING: Make sure that line is fed out 

before operation. Make sure motor is up to 

full speed before trimming 

WARNING: Use only 0.065” (1.65 mm) 

diameter cutting line. 

Other sizes of line will 

not feed properly and will result in improper cutting 

head function or can cause serious injury. Do not use 

other material such as wire, string, rope, etc. Wire can 

break off during cutting and become a dangerous 

projectile that can cause serious injury.

1. Flower Guard (SEE FIG. F1, F2)

Push the Flower Guard (6) out before trimming, as 

shown in Fig G1, G2. 

2. Trimming (SEE FIG. G)

Position the trimmer head as shown in Fig G for 

trimming. 

Keep the bottom of the trimmer head just above the 

ground and at an angle. Allow only the tip of line to 

make contact. Do not force trimmer line into work 

area.

3.  AUTOMATIC LINE FEED SYSTEM

When initially switching on the trimmer, a small 

length of line is fed out. A ‘clattering’ noise will be 

heard when the lines hit the line cutter. DO NOT BE 

ALARMED this is quite normal. After about 5 seconds 

the line will be cut to the correct length and the noise 

will reduce as the motor receives full speed.

If the noise of the line being cut can’t be heard, 

more line will be fed out. To feed more line, it is first 

necessary to allow the trimmer to stop completely, and 

then restart, allowing the motor to reach full speed.

Repeat above until you hear the lines hitting against 

the line cutter. (Do not repeat this procedure more 

than 6 times)
