For safety reasons, do not use metal reinforced line.
2. Pinch the sloed area on the both sides of the spool housing to unhook the boom cap.
3. Take out the spool and pull o the old line. Put one end of new line through the spool holes and pull it unl the length is equal between each part of the
line.
4. Wind up the line in the correct direcon as indicated on the spool.
5. Hook each end of the line in the slot on the edge of the spool, and then put the ends through the eyelets on the housing. Make sure that the spring and
the washers are in place.
6. While holding the spool against the housing, pull the line ends to release them from the slot.
7. Line up the slot on the boom cap with the hook on the housing, press the cap against the housing unl it clicks.
Fast winding thread heads (not included with all models): Align the spool holes with the corresponding head holes, align the two ends of the cung thread
and rotate the head by winding the cung thread.
Blade (Picture H)
• Check the blade and the fasteners for looseness, cracking, or bending.
• Check the cung edges and reform with a at le
1. Keep the end corner sharp.
2. Round the root of the edge, using round le.
3. Do not use water when using a grinder.
• It is recommended that ling should be done by professionals.
• Especially regarding ling the saw blade, Leave it to the professionals.
WARNING: Make sure that the engine has stopped and is cool before performing any service to the machine. Contact with moving cung head or hot muf-
er may result in a personal injury.
WARNING&DANGER
Use extreme cauon when operang over bare spots and gravel, because the line can throw small rock parcles at high speeds.
Debris shields on the unit cannot stop objects which bounce or ricochet o hard surfaces.
Cung with a blade
There are many dierent types of blades, however the two most commonly used are the following.
BRUSH CUTTER BLADE is used for cung brush and weeds up to 3/4” in diameter.
DANGER! DO NOT TOUCH THESE TYPES OF OBJECTS WITH BLADE: Ulity wires, metal stakes, rubber, rocks, masonry, fences.
NEVER USE A BRUSH CUTTER FOR CUTTING TREES.
Do not cut with dull, cracked or damaged metal blade.
Before cung growth, inspect for obstrucons such as boulders, metal stakes or strands of wire from broken fences. If an obstrucon cannot be removed,
mark its locaon so that you can avoid it with the blade. Rocks and metal will dull or damage a blade. Wires can catch on the blade head and ap around or
be thrown into the air.
Blade thrust is the reacon which may occur when the spinning blade contacts anything it cannot cut. This contact may cause the blade to stop for an instant
,and suddenly “thrust” the unit away from the object that was hit. This reacon can be violent enough to cause the operator to lose control of the unit. Blade
thrust may occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is dicult to see the material being cut. For
cung ease and safely, approach the weeds being cut from the right to the le,in the event that an unexpected object or woody stock is encountered,this
could minimise the blade thrust reacon.
Cung with a nylon head
The CUT - OFF KNIFE will be on the right side of the debris shield.
If the brush cuer is equipped with an bump feet head in order to increase the length of the cung line press the cung head on the ground by guiding it
downwards.
WARNING! The proper debris shield must be in place on the unit when nylon cung line is used. The cung line can ap around if too much line is exposed.
Always use the plasc debris shield with cut-o knife when using nylon cung heads.
For nearly all cung, it is good to lt the line head so that contact is made on the part of the line circle where the line is moving away from you and the
debris shield.
WARNING&DANGER
Tilng the head to the wrong side will shoot the debris TOWARDS you. lf the line head is held at to the ground so that cung occurs on the whole line
circle, debris will be THROWN at you, drag will slow the engine down, and you will use up a lot of line.
WARNING&DANGER
Never use wire or wire-reinforced line in place of nylon trimmer line. Load your nylon line cung head only with nylon trimmer line of the proper diameter.
