EMISSION INFORMATION
WARNING
WARNING TO ALL CALIFORNIA
AND OTHER STATES OPERATING
OUTDOOR POWER EQUIPMENT
Under California Law and under the
laws of several other states you are
not permitted to operate an internal
combustion engine using
hydrocarbon fuels on any forest
covered, brush covered or grass
covered land or on land covered with
grain hay or other flammable
agricultural crop, without an engine
spark arrester in continuous effective
working order.
The engine on your power equipment,
like most outdoor power equipment,
is an internal combustion engine that
burns gasoline, a hydrocarbon fuel.
Therefore, your power equipment
must be equipped with a spark
arrester muffler in continuous
effective working order. The spark
arrester must be attached to the
engine exhaust system in such a
manner that flames or heat from the
system will not ignite flammable
material.
M-F, 8 a.m. to 5 p.m.
Central Time
Failure of the owner/operator of the
equipment to comply with this
regulation is a misdemeanor under
California law, and may also be a
violation of other state and or federal
regulations, laws, ordinances, or
codes. Contact your local fire
marshal or forest service for specific
information about what regulations
apply in your area.
The standard muffler installed on the
engine is not equipped with a spark
arrester. One must be added before
use if this machine is intended to be
used in an area where a spark
arrester is required by law. Contact
the local authorities if these laws
apply to you. See your authorized
engine dealer for spark arrester
options.

3.3 TRIMMING
WARNING
Wear safety glasses during operation. Wear proper
clothing to protect feet, legs, and other exposed body
parts.
WARNING
Inspect and clean engine before each use. Debris
accumulation around the muffler can cause a fire.
The intended use of the EZ Trim Mower is trimming, mowing,
and edging. It can be used as a mower or trimmer and
edger after mowing with a lawn mower.
To begin trimming, with the engine running, place the trimmer
head on the ground and begin walking slowly. The wheels
should remain grounded at all times to prevent undue
pressure on the trimmer head. The cutting radius is
dependent on the amount of cutting string used and type of
application. For difficult conditions and edging, using less
than the full cutting radius is recommended.
3.5 OFF CENTER TILT FEATURE
(OCT)
On models 74050, 74060, 74065, 74450, 74455 the OCT
feature is used to edge and trim in hard to reach places.
This features enables both the trimmer head and body to tilt
for trimming close to the ground. The degree of tilt is
dependent on the setting selected on the tilt control grip
located on the right side of the EZ Trim Mower.
Four settings are available:
1. Level. The tilt control grip is set in the position
closest to the rear of the trimmer.
2. 5.4 degrees. The tilt control handle is set in the
second position from the rear of the trimmer.
3. 10.3 degrees. The tile control handle is set in the third
position from the rear of the trimmer.
4. 13 degrees. The tilt control grip is set in the position
closest to the front of the machine for maximum tilt.
3.4 SELF PROPELLED OPERATION
The Self Propelled EZ Trim Mower is used in either push or
self propelled mode.
1. Pull up the self propelled bail located under the
handlebar to start the self propelled mode.
2. Adjust trimmer speed with the shift lever. Position 1
is the slowest and position 3 is the quickest. (The
ground speed ranges from 1 mph in 1st gear to 2
mph in 3rd gear).
3. Operate EZ Trim Mower safely and as intended.
4. To stop the mower release the bail.

4.1 PARALLEL TRIMMING (MODELS
73265, 73350, & 73455)
The EZ Trim Mower trimmer body can be adjusted to mow
at an angle. The trimmer body will move up to 2" to the left
or the right. This allows the machine to edge and trim in
hard to reach places. To adjust the parallel trimming setting:
1. Loosen two nuts on the bottom of the trimmer called
out in Fig. #4; the first (A) is located behind the
trimmer spindle, while the other (B) is in the center of
the back of the transmission support plate. Do not
adjust parallel trimming with the trimmer axle. This
will cause the drive chains to fall out of adjustment.
2. Pivot the trimmer body, on the slotted holes, to the
left or right. The trimmer body can pivot either left or
right up to 2".
3. Tighten the nuts loosened in step #1.

4.6 CUTTING STRING REPLACEMENT
WARNING
Before inspecting or servicing any part of the machine,
disconnect the spark plug wire from the spark plug and
make sure all moving parts have come to a complete
stop.
1. Feed the cutting string through the second hole on
either end of the trimmer head leaving approximately
8 inches for the cutting surface. Total recommended
string length is 20-1/2 inches.
2. Continue by weaving the cutting string through the
first hole directly beside the second hole used in Step
1. Pull the cutting string tight.
3. Loop the cutting string back and feed through the first
hole on the opposite end of the trimmer head.
4. Feed through the remaining second hole and pull the
cutting string tight. The cutting strings in the middle
two holes should be the same length. If the length
differs, cut to an even length.
The cutting string can also be wrapped in a variety of ways.
Refer to Fig. #9 and Fig. #10 for examples.
Cutting string is available in two thicknesses, .130 mil
(standard) and .155 mil (heavy duty). The type of string
selected is dependent on the conditions and material being
cut.
Heavier string than .155 mil can be use by making the holes
in the trimmer head larger. The decision to drill the holes
bigger shortens the life of .130 mil and .155 mil string if used
again.
The wrapping method and cutting string thickness chosen
is ultimately based on what is determined the best for the
operator.
When completed, the trimmer head should resemble Fig.
#8.
