REMOVING THE CUTTING HEAD ATTACHMENT
WARNING:
blade guard is attached to the trimmer head. Always make sure to remove the plastic cutting
guard shield when using the brush cutter attachment. Failure to do so may cause serious
personal injury or damage to the unit.
If you want to trim or remove thicker, tougher and thornier brush you must use the metal brush cutter
attachment. This is supplied with its own blade guard which must be securely attached to the trimmer
head. In order to do this, both the cutting head attachment and cutting head shield must first be
removed from the trimmer unit. To safely attach the brush cutter to the unit follow these instructions:
Air Filter Cover
1. Remove the cutting head shield from the shaft
housing (Fig. 1).
2. Position the cutting head attachment as shown
(Fig. 7). Align the shaft bushing hole with the
locking rod slot. Insert the locking rod into the
shaft bushing hole.
3. Hold the locking rod in place by grasping it next
to the boom of the shaft housing (Fig 7).
4. While holding the locking rod, remove the cutting
head attachment by unscrewing it clockwise (Fig.
8). Store the cutting head attachment for future
use.
INSTALLING THE BRUSH BLADE GUARD
1. Place the brush blade guard onto the trimmer head
with the three holes aligned.
2. Attach the blade guard to the trimmer head with
the three guard bolts and nuts using a 7/16 inch
closed-end or socket wrench (Fig. 9).
