LINE REPLACEMENT
ARTY RULES
1 . Shut down the trimmer to make certain the head cannot turn
while working with the head.
2. Check mounting of cutting head on trimmer and tighten if it
is loose.
3. Inspect head for wear, chips or cracks. Replace parts or entire
head if needed.
4. Always use line that is the correct diameter and type for this
unit. Do not use metal reinforced or metal line.
5. Make sure the two retaining pawls spread out to the periphery
of the cover windows.
6. Check the head for deflection or abnormal noise by rotating
the head by hand. Deflection or abnormal noise may cause
vibrations, which will cause the cutting line to weld together. It
is also potentially dangerous.

REFILLING TRIMMING LINE
1. For replacement line, use a diameter of .095 in. (2.4 mm). The
spool is capable for a line up to 20 ft. (6 m) on the 4 in. head.
Avoid using a larger line as it may cut down the trimming
performance.
2. Pinch the slotted area on the both sides of the spool housing
to unhook the bottom cap.
3. Take out the spool and pull off the old line. Put one end of
new line through the spool holes and pull it until the length is
equal between each part of the line.
4. Wind up the line in the correct direction as indicated on
the spool.
. 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 bottom cap with the hook on the
housing, press the cap against the housing until it clicks.
BLADE REPLACEMENT
SAFETY RULES
1. Shut down the trimmer to make certain the blade cannot turn
while working with the blade.
2. Make certain the correct shield is securely attached and in
the correct position.
3. Always wear gloves when working with the blade.
4. Never attempt to sharpen the blade. If the blade is dull,
cracked, bent or out of balance replace the blade with the
replacement blade made specifically for this unit. A worn,
damaged or cracked blade can beak and pieces of the
damaged blade can become dangerous projectiles. Although
aftermarket blades may fit this unit, it is potentially dangerous
to put these blades on your unit. Use only a new 4 point 8
inch brush blade intended for this unit.
REPLACEMENT PROCEDURE:
. Insert a 1/8 in., 4 mm hex tool or equivalent fully into the gear
case hole.
. Turn the blade until you feel the tool drop into the hole in
cover plate/spacer A. Verify the blade does not turn. The
blade nut is a left-hand thread. Turn clockwise to loosen and
counter-clockwise to tighten. Make sure the tool remains in
the hole, then loosen the blade nut as shown. Pay attention to
the order and orientation of the parts as they
are removed.
Installation is the reverse of removal. Tighten the blade nut
with a torque wrench.
