It may be necessary to loosen the retaining

nut and clamp screw to adjust cutting attach-

ment shield mounting plate.

2. Fit the two shims and the bracket over

the outer tube and loosely install the

four socket-head screws.

See Figure 9.

WARNING!
The line cutter is very sharp.

Wear gloves to protect your

hands when handling.

To Change Position of Line Cutter

hex wrench. See Figure 9A.

NOTE:

Be careful to not lose the 2 nuts in the cut-

ting attachment shield, they are

not captured.

The line cutter can be positioned in

2 positions to obtain different line length

for cutting.

Install the Trimmer Head.

gearcase output shaft faces UP.

2. Remove and discard the black plastic

retaining plug from the output shaft.

See Figure 10.

3. Rotate the holder until the hole in the

holder aligns with the notch on the

gearcase. Use the long end of the hex

wrench to lock the holder and output

shaft. See Figure 10.

4. While holding the hex wrench, thread

the trimmer head onto the output shaft,

turning counter-clockwise. Using hand

pressure only, tighten the trimmer

head firmly on the output shaft.

IMPORTANT!

The trimmer head has a left-hand thread.

For removal turn the trimmer head clock-

wise.

WARNING!

A standard grass trimmer with a loop

handle should NEVER be operated

with blade-type attachments. For

blade use the trimmer must be fitted

with a bicycle-type handlebar or

loop handle with a barrier bar that

is located in front of the operator to

reduce the risk of the operator from

coming in contact with the cutting at-

tachment (per ANSI B175.3). When

using a blade, the unit must also be

equipped with a harness or strap.
