Model 73040/73050/73450 Trimming
Adjustments
Trimming Adjustments are used to edge
and trim in hard to reach places. To begin
using trimming adjustments:
1. Loosen the right axle nut located directly
behind the trimmer.
2. Lift the right wheel and pull back. The
wheel and axle will rotate backwards due to
a slot cut in the bottom of the trimmer
frame.
3. Tighten the nut loosened in Step 1.
4. Push the trimmer slowly.
5. When finished using the offset feature,
loosen the right axle nut again and lift the
wheel and push forward.
Use caution when operating near loose
gravel or areas where loose debris may be
encountered.
The intended use of the EZ TrimMower is trim-
ming, mowing and edging. It can be used as a
mower or trimmer and edger after mowing with a
lawnmower.
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.
6. Tighten the right axle bolt and resume
regular trimming/mowing.
Model 74040/74050 Off Center Tilt
Feature (OCT)
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 close cutting. The degree of tilt is
dependant on the setting selected on the tilt
control grip located on the right side of the
EZ TrimMower. For maximum tilt, move the
tilt control grip to the setting closest to the
front of the machine. Resume regular
trimming/mowing by placing the tilt control
grip back in the setting near the rear of the
trimmer.

Service & Maintenance
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.
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. The cutting
string can also be wrapped in a variety of ways.
Refer to the figures below for two examples.
Figure 10
When completed, the trimmer head should
resemble Figure 9.
