Cutting Cord Recommendations
Cutting cord is available in Blue (175 mil) and Green (155 mil).
Because conditions and vegetation vary so much, you should
experiment with cord weights (diameters) to discover what works
best for your particular mowing and trimming situations. Here are a
few things to keep in mind:
• If the cutting cord is purchased in rolls, cut to 25” lengths.
• Cord life depends on trimming conditions. Replace cords when
they become broken or frayed.
• e smallest diameter cord combined with the fastest engine speed
provides the best grass trimming performance. e 175 mil cord
is recommended for thicker growth such as berry cane, bramble,
thistle, and ragweed.
• Ease the ends of the cord into heavy growth and move slowly
through thick growth. If there are woody weeds in the material
you are cutting, the cutting cords may wrap around the stalks they
cannot cut, and pull away from the trim ball.
• Installing two (2) cords, 180 degrees apart, of equal length on the
line plate, is the best method for optimal trimming performance.
• When replacing cords, do it one at a time and use the old cord to
mark the position for the new cord that you are replacing.
• If the cord breaks off flush at the line plate, use needle nose pliers
to pull out the old cord.
• Storing the cord in a plastic bag with a damp sponge or cloth will
help keep it pliable. You can also soak your cutting cord in a bucket
of room temperature water for a few days before use to make it
more pliable.
• UV light can degrade cord, store out of direct sunlight.
DO NOT USE DIFFERENT WEIGHT CORDS ON THE
TRIM BALL AT THE SAME TIME. THIS CAN CAUSE
EXCESSIVE VIBRATION AND MAY DAMAGE THE
MACHINE.
12
Page 13
Trimming Ball
Allow the front end of the machine to rest lightly on the trim ball
as you are trimming. e trim ball should glide on the ground as
you maneuver the machine. To achieve the best and smoothest
cut, do not lift up on the handlebar while operating your trimmer/
mower. Lifting the handlebar will force weight down on the
trim ball. is uses more energy, slows the cutting, and produces
an unsatisfactory cut. Ideally, the trim ball should lightly rest on
the ground while the wheels balance most of the weight of the
machine.

4. Looking down at the top of the frame, turn the trim ball
clockwise until it unscrews completely from the bearing housing.
NOTE: If the trim ball continues to turn, but does not come off,
check to be sure that you locked the screwdriver into the shaft. If
the trim ball will not turn by hand a 9/16” socket wrench can be
used on the bolt (inside the bottom of the trim ball) to loosen it.
You may need to clean grass or debris out of the recess first.
5. Slide the line plate and spacers off the shaft.

WARNING
e trimmer can easily throw debris at great velocity, which
could cause personal injury or property damage. Do not run the
machine over loose gravel or mulch with the trim ball spinning.
e trimmer/mower discharges cut material to the right. Always
try to cut and trim with the uncut tall grass or weeds on the left.
• Always check your work area before trimming and remove any
debris that might tangle or damage the machine.
• If you do run into debris and the trimmer becomes tangled,
turn off the engine and disconnect the spark plug wire before
attempting to untangle the machine.
• For the neatest appearance, do your trimming first, discharging
clippings away from borders and shrubs, then do your mowing.
• Many owners like to mow easy, open areas with their regular
riding or walk behind mower and finish trimming all the odd
and hard-to-reach spots with the trimmer/mower.
Heavy Growth Trimming Recommendations
• Take your time in heavy growth.
• Be sure to keep uncut material to your left, maintaining a clear
discharge area to your right.
• If the machine cannot do it all in one pass, overlap half of the
cutting swath.
• If the grass is very thick and heavy, try raising the trim ball off
the ground a few inches by pushing down on the handlebar. Cut
the material at this height, and then make a second pass with the
trim ball close to the ground.
• Ease the trimmer/mower into denser growth. If the material is
too tough or woody to cut, the cutting cords will wrap around it,
wear down, or even break off.
• Sometimes the growth is so heavy, you cannot mow it in rows.
Use a forward and back “vacuum cleaner” motion in these cases.

Operating Environment
Wet Environments
You can use the trimmer/mower in damp and wet conditions, after
a rain, or in the early morning dew without clogging or stalling.
You can mow wet areas such as ditches and around ponds.
Note: NEVER mow in the rain. Water on the spark plug may
cause the engine to stall.
Dry Environments
When trimming and mowing in very dry conditions, be extra
cautious of cut grass, chaff, weeds, seeds, etc., accumulating on the
engine, especially around the recoil-starter housing and engine
cooling fins. Please see the Engine Owner’s Manual for more
detailed information on cleaning the air intake, air filter, and
cooling system on the engine.
!
WARNING
Frequently remove debris from the recoil guard on top of the
engine and the cooling ns on the front of the engine to prevent
overheating and engine damage.
Slopes
You can trim and mow on slopes up to 20 degrees. Continuous use
on slopes steeper than 20 degrees may deprive the engine of
adequate lubrication, and damage components.
Windrows
e trimmer/mower cutting cords cut tall grass in one pass, so
you can collect clippings and leaves for mulch without raking. e
machine ejects cut material to its right side, so you can use it like a
lawn broom to make cleanup easy and to create windrows
Firebreaks
Use your trimmer as a labor saving tool to cut material when
creating firebreaks.
Garden Clean-Up
e trimmer/mower is perfect for cutting down dead perennials,
annuals, and wildflowers, saving you hours of hand pruning and
deadheading. You can also re-cut downed material a second time to
create mulch for garden beds.

Troubleshooting
PROBLEM SOLUTION
Trim ball keeps spinning or spins • Check for proper alignment of the v-belt. Check it against
when you release the safety bar. Figure 20 in the “Replacing the Belt” section on page 19.
• If the trimmer head keeps spinning when you release the
safety bar, see “Adjusting the Belt Tension through the
Trimmer Control Cable” on page 18.
• If none of the above helps, visit our web site at www.
dirtyhandtools.com or call 1-877-487-8275 for assistance.
Cutting cords are breaking. • e cords may be too dry. Store cords in a plastic bag with a
damp sponge or cloth to make them less prone to breaking
or soak them in a bucket of water for a few days.
• You may be trying to do too much too fast. Ease into the
material you are cutting; let the cord tips do the work. Take
small bites of tall or tough vegetation. Cut half a swath at a
time, keeping the cut area to the discharge or right side of
the trimmer. Go over tall material twice, the first time with
the trim ball tilted up and back; the second time with the
trim ball on the ground.
• Make sure that you are not hitting the cords against a stone
or a chain-link fence. e cords won’t last as long against
obstacles as in the open. Work on controlling the cutting
pattern. With practice, you’ll learn to cut closer to obstacles
without hitting them.
`
Cutting Cords are pulling out. • You may be moving too fast into tough, woody growth. In
doing so, the cords may wrap on stalks and pull out. Check
the operating tips in the section above on breaking cords.
• Make sure that you are not trying to cut material too heavy
for the cord. e design of your trimmer is to cut green
material up to about the thickness of a pencil.
• If none of the above helps, visit our web site at www.
dirtyhandtools.com or call 1-877-487-8275 for assistance.
e trim ball is wearing too quickly. • You may be pushing the trimmer head down into the
ground. e trimmer/mower works best with a light touch,
with the trim ball resting easily on the ground.
• You may be hitting the trim ball against rocks, concrete
driveways or other hard obstacles. Try approaching them
slowly, and from different directions, to avoid unnecessary
wear.
• If none of the above helps, visit our web site at www.
