accessories and trimmer line that are designed for
◾ use with this machine. Although certain
unauthorized attachments might be fitted to the
HENX line trimmer, their use may be extremely
dangerous, and/or damaging to the tools.

◾ To reduce the risk of serious injury, never use
wire or metal-reinforced line or other material in
place of

corrosive and may cause damage to the eyes or skin. It may
be toxic if swallowed.
◾ Exercise care in handling batteries in order not to short the
battery with conducting materials such as rings,bracelets,
and keys. The battery or conductor may overheat and cause
burns.
◾ When servicing, use only identical EGO replacement parts.
Use of any other accessory or attachment may increase the
risk of injury.

CONNECTING THE LINE TRIMMER ATTACHMENT TO THE
POWER HEAD
This line trimmer attachment is designed for use with HENX
Power HeadH36DG65.
See “ INSTALLING AN ATTACHMENT TO THE POWER HEAD’’
sectioninthepowerhead H36DG65 operator’smanual.
ADJUSTING CUTTING LINE LENGTH (Fig.E)
The trimmer head allows the operator to release more cutting
line without stopping the motor. As line becomes frayed or worn,
additional linecan bereleased by lightly tapping the trimmer head
on the ground while operating the trimmer (Fig.E).
WARNING: Do not remove or alter the line-cutting blade assembly.
Excessive line length will cause the motor to overheat and may result in
serious personal injury.
For the best performance, knock the trimmer head on naked ground or hard
soil. The motor will become overheated if you release trimmer line on
ground with long grass. Always keep the trimmer line at the full length. Line
release will become more difficult as the cutting line becomes shorter.
When the cutting line breaks from the line outlet or the cutting line is not
released when tapping the trimmer head, you should remove the remain
cutting line from the spool retainer and install the cutting line by following the
steps below:
1. Remove the battery pack.
2. Rotate the bump head on the trimmer head until the
arrow on the bump head aligns with the arrow on trimmer
head housing.
3. Insert the line into the mounting hole inside the eyelet.Push
and pull the line from the other side until equal amounts of line
appear on both sides of the spool.
4. Rotate the bump head clockwise after line insertion until all
trimmer line are well winded(only 350mm trimmer line will be
left as cutting diameter.)
3-TEETH BLADE REPLACEMENT(Fig.I and Fig. J)
When using this machine in bushes or reeds, the trimmer
head shall be replaced with 3-teeth blade by following the
steps below.
Insert steel rod into bump head/blade mounting hole so
that motor will stop run. Hold and rotate the trimmer head
in clockwise and take it out. Pre-install the manufacturer
recommended 3-teeth blade on blade cover plate, align the
r hole on 3-teeth blade with bulge on blade cover plate and
then install the blade cover plate, tighten the square head
nut with slotted screw drive.
