READ THIS INFORMATION
Before you use your new trimmer/brushcutter, read the following
helpful hints to get you started.
Fueling
DANGER:
Gasoline is extremely flammable and explosive.
A fire or explosion from gasoline will burn you and
others.
1. Obtain a clean container that is approved for use with gasoline.
2. Mix all of the 2-cycle oil provided with 1 US gallon of 87-octane, unleaded
gasoline (50:1).
3. Fill the trimmer’s gas tank carefully.
Cold Starting vs. Warm Starting
When you restart the trimmer/brushcutter and you are not sure whether the engine is still warm, set
the choke lever to RUN (Choke Open) and pull the starter cord. If the engine does not start within
5 pulls, see To Start a Cold Engine later in this manual.
Flooded Engine
Will the engine start? If not, it may be flooded. Relax, this is easy to correct. Set the choke lever to
RUN (Choke Open). Squeeze the trigger and pull the starter cord quickly for 10 to 12 pulls.
If the engine does not start, refer to Troubleshooting later in this manual or call toll-free at
1-866-574-9242 (US) or 1-866-574-9243 (Canada).
WARNING: The engine exhaust from this product contains chemicals known to the State

serious injury.
WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.

Note Advises you of additional information concerning the operation or maintenance of the
equipment.
Introduction

This product has been designed and manufactured to
meet or exceed the requirements of the current version of
ANSI B175.3, safety requirements for gasoline-powered
string trimmers and brushcutters.
Physical Condition of the Operator. Do not operate
this product when tired, ill, or under the influence of
alcohol, drugs, or medication.
Clothing Requirements. Always wear long heavy
pants, boots, and gloves. Do not wear loose cloth-
ing, jewelry, short pants, sandals, or go barefoot.
Secure hair so that it is above shoulder level to avoid
entanglement in moving parts.
Protective Accessories Requirements. Wear eye
protection marked to comply with ANSI Z87.1
standards when operating this product. Wear hearing
protection during extended periods of operation.
Condition of Trimmer Before Use. Inspect the
product before each use. Replace damaged parts.
Check for fuel leaks. Make sure all fasteners are
in place and secure. Replace cutting attachment
parts that are cracked, chipped, or damaged in any
way. Make sure the cutting attachment is properly
installed and securely fastened. Be sure the cutting
attachment shield is properly attached and in the
position recommended by the manufacturer. Use
only flexible, non-metallic line recommended by the
manufacturer. For example, never use wire or wire-
rope, which can break off and become a dangerous
projectile.
Proper Stance. Keep firm footing and balance. Do
not overreach. Keep the cutting attachment below
waist level. Keep all parts of your body away from
the rotating cutting attachment and hot surfaces.
Exhaust Gases. Never start or run the product inside
a closed room or building; breathing exhaust fumes
can cause illness or death.
Fueling. Mix and pour fuel outdoors where there are
no sparks and flames. Slowly remove the fuel cap
only after stopping the engine. Do not smoke while
fueling or mixing fuel. Wipe spilled fuel from the
product. Move at least 30 ft. (9 m) away from the
fueling source and site before starting the engine.
Work Area. Clear the area to be cut before each
use. Remove all objects, such as rocks, broken glass,
nails, wire, or string, that can be thrown or become
Safety Rules
WARNING:
Read and understand all instructions. Failure to follow all instructions may result in serious personal injury
as well as damage to the product.
entangled in the cutting attachment. Clear the area of
children, bystanders, and pets. At a minimum, keep
all children, bystanders, and pets outside a 50 ft.
(15 m) radius. Because there still may be a risk of
injury to bystanders from thrown objects, bystanders
should be encouraged to wear eye protection. If you
are approached while operating the product, stop the
engine and the cutting attachment.
Dangerous Environments. To avoid falling, do not
use the product in damp or wet locations.
Controlling the Product. During carburetor adjust-
ments the cutting attachment may spin. Therefore,
you should wear protective equipment and observe
all safety instructions when adjusting the carbure-
tor. For products equipped with a clutch, be sure the
cutting attachment stops turning when the engine
idles. When the product is turned off, make sure the
cutting attachment has stopped before setting down
the product.
Use the Right Product. Use the product for the
intended purpose only.
Condition of Brushcutter Before Use. The handles
shall be mounted according to the manufacturer’s
instructions. Do not attach any blade to a product
without proper installation of all required parts. Fail-
ure to use the proper parts can cause the blade to fly
off and seriously injure the operator and/or bystand-
ers. Discard blades that are bent, warped, cracked,
broken, or damaged in any way.
Use the Right Equipment. Always use the barrier
bar on the front handle and the shoulder strap with
the brushcutter.
Blade Thrust. Blade thrust may occur when the
spinning blade contacts an object that it does not im-
mediately cut. A blade thrust can be violent enough
to cause the product and/or operator to be propelled
in any direction, and possibly lose control of the
product. Blade thrust can occur without warning if
the blade snags, stalls, or binds. This is more likely to
occur in areas where it is difficult to see the material
being cut.
Stopping the Product. A coasting blade can cause
injury while it continues to spin after the engine is
stopped or throttle is released. Maintain proper con-
trol until the blade has completely stopped rotating.

Operating the Trimmer
WARNING:
Always hold the string trimmer away from the
body, keeping clearance between the body and
the product. Any contact with the housing or
string trimmer cutting head can result in burns
and/or other serious personal injury.
To Operate the Straight Shaft Trimmer
(Model No. 51973)
See Figure 16a.
To operate the straight shaft trimmer:
1. Start the trimmer.
2. Hold the trimmer at waist level with your right hand on
the trigger handle and your left hand on the front handle.
3. Place the product on the right side of your body with the
engine behind and away from your body.

Operation
To Advance the Cutting Line
See Figure 16b.
To advance the cutting line:
1. Start the trimmer.
2. Tap the retaining cap lightly on the ground while the mo-
tor is running. The line will only advance with the engine
at full throttle. Do not hold the retaining cap on the
ground.
Note: The line cutting blade on the grass deflector will
cut the line to the proper length.
Note: To help prevent line tangle, tap only once to
lengthen the line. If additional line is required, wait a few
seconds before retapping the retaining cap. Do not allow
the line to wear too short. Keep the cutting line at full
length.

Operating the Brushcutter
(Model No. 51993)
See Figure 17.
To operate the brushcutter:
1. Start the brushcutter.
2. Hold the brushcutter at waist level with your right hand
(arm extended) on the trigger handle and your left hand
on the front handle.

engine behind and away from your body.

Cutting Tips
See Figure 18.
1. Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating position is shown in
Figures 16a and 17.)
2. Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
3. The straight shaft trimmer cuts when passing the unit
from left to right. This will avoid throwing debris at the
operator. Avoid cutting in the dangerous area shown in
figure 18.
4. Use the tip of string to do the cutting; do not force string
head into uncut grass.
5. Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
6. Avoid trees and shrubs. Tree bark, wood moldings, sid-
ing, and fence posts can easily be damaged by the string.
