General Trimmer Head Maintenance Information
The most common cause of trimmer
head malfunction is poor maintenance, especially true for tap-for-line,
bump-feed, and fully automatic heads.
Customers buy these heads for
convenience so they don’t have to
reach down and advance the line–yet
that added convenience often means
the head is not properly maintained.
A Few Tips
■ Clean the head thoroughly each time
line is refilled. Wipe all grass and
debris from internal parts. Water will
dissolve accumulated buildup, but a
cleaner such as 409™ will aid in the
task.
■ Replace worn eyelets. Never run a
trimmer head without eyelets installed. Running with an eyelet
missing will cause the trimmer line to
wear into the body of the head as
well as create excessive vibration.
■ Replace any noticeably worn parts. A
knob at the bottom of a head is a
wear part if it contacts the ground,
especially in abrasive soil conditions
and when the head is run against
sidewalks and curbs.
■ When winding line, keep both strings
separate. Try to wind as evenly as
possible to prevent snarling and
reduce vibration.
■ Trim line ends to equal length from
the eyelet. Operation with uneven
length trimmer line will cause
excessive vibration.
■ Always replace worn or damaged
parts promptly .
■ Make sure line is wound in the
correct direction for the rotation of
the head–
For heads with a LH arbor bolt,
wind line counterclockwise as viewed
from the knob at the end of the
trimmer head.
For heads with a RH arbor bolt,
wind line clockwise as viewed from
the knob.
“Clockwise for RH,
Counterclockwise for LH”
Any plastic material can dry out,
especially when stored at high temperature and when exposed to direct
sunlight. To prevent this, Shindaiwa
packages much of their trimmer line in
all-plastic holders so the line can be
soaked in water to restore moisture.
Trimmer line with very low moisture
content is brittle and inflexible. Winding dry line on a trimmer head can be
very difficult. After soaking in water,
the same line will become very flexible
and far tougher, and service life will
be significantly extended. NOTE: This
also applies to flail blades.
CAUTION: Remove the bearing or
bushing from from Super Flail blades
before soaking in water.
The Shindaiwa Warranty
Shindaiwa warrants trimmer heads to
be free of defects in materials and
workmanship for 90 days. The warranty is for replacement parts only –
not the entire trimmer head. Damage
caused by wear, running with missing
parts, etc. is not covered.
Q

A

for different applications. Some heads
feature manual adjustment of line
length while others are tap-for-line
models. In addition, some trimmer
heads are intended for consumer use
and others are intended primarily for
commercial applications.

Remove the knob and spring (turn
counterclockwise to remove).
Remove the line spool. Clean the spool, housing and eyelets.
4 5 6
Reattach the eyelets if they were
removed. Never operate a trimmer
head head without eyelets!
Replace the line by threading it
through the eyelet in the spool until
the line ends are of about equal
length. Refer to the Line Chart
(above) for the proper amount of line.
Inspect for wear and damage.
Replace damaged components.
Bend the line at the eyelet to form two
lengths. Wind both ends clockwise as
viewed from the underside of the
head.
4
To advance line: With the engine off, loosen the bottom knob a few turns in
the direction of rotation. Grasp the trimmer head in both hands. Rotate the
bottom of the spool clockwise and pull the line through the eyelets. Re-tighten
the knob before operating the trimmer.
7 8
Use your finger to separate the line
into two sections. Doing so will assist
in a smooth line feed when the head
is reassembled.
9 10
Hold the spool over the housing and
feed one line end into an eyelet. As
you place the spool in the head, feed
the other line into the opposite eyelet.
Make sure one line does not slide
under the spool.
11 12
Holding the spool and wound line
in one hand, place the lines 180
degrees apart.
Tip: Sometimes it’s easier to remove
one eyelet to install the second piece
of line. Slide the eyelet over the line
two to three inches, then push the
eyelet in place as the spool is replaced in the housing.
