Safe Handling Of Gasoline:  
Slope Operation  
To avoid personal injury or property damage use extreme  
care in handling gasoline. Gasoline is extremely flammable  
and the vapors are explosive. Serious personal injury can  
occur when gasoline is spilled on yourself or your clothes  
which can ignite. Wash your skin and change clothes  
immediately.  
Slopes are a major factor related to slip and fall accidents  
which can result in severe injury. Operation on slopes  
requires extra caution. If you feel uneasy on a slope, do not  
trim or mow it. For your safety, use the slope gauge included  
as part of this manual to measure slopes before operating  
this unit on a sloped or hilly area. If the slope is greater than  
15 degrees, do not trim or mow it.  
1. Use only an approved gasoline container.  
2. Extinguish all cigarettes, cigars, pipes, and other  
sources of ignition.  
3. Never fuel machine indoors because flammable  
vapors will accumulate in the area.  
4. Never remove gas cap or add fuel while the engine  
is running. Allow engine to cool at least two minutes  
before refueling.  
5. Never over fill fuel tank. Fill tank to no more than 1/2  
inch below bottom of filler neck to provide space for  
fuel expansion.  
Do:  
1. Trim or mow across the face of slopes; never up or  
down. Exercise extreme caution when changing  
direction on slopes.  
2. Watch for holes, ruts, hidden objects, or bumps.  
Tall grass can hide obstacles.  
3. Always be sure of your footing. A slip and fall can  
cause serious personal injury. If you feel you are  
losing your balance, release the trimmer head  
control handle immediately, and the trimmer head  
will stop rotating within a few seconds.  
6. Replace gasoline cap and tighten securely.  
7. If gasoline is spilled, wipe it off the engine and  
equipment. Move unit to another area. Wait 5  
minutes before starting the engine.  
Do Not:  
8. Never store the machine or fuel container inside  
where there is an open flame, spark, or pilot light as  
on a gas water heater, space heater, furnace,  
clothes dryer or other gas appliances.  
9. To reduce fire hazard, keep the string trimmer  
mower free of grass, leaves, or other debris build-  
1. Do not trim or mow near drop-offs, ditches or  
embankments. The operator could lose footing or  
balance.  
2. Do not trim or mow slopes greater than 15 degrees  
as shown on the slope gauge on page 6.

soaked debris.  
10. Allow mower to cool at least 5 minutes before  
storing.  
disconnect the spark plug wire and ground against  
the engine. Thoroughly inspect the string trimmer  
mower for any damage. Repair the damage before  
starting and operating.  
7. Never attempt to replace the trimmer line or make a  
cutting height adjustment while the engine is  
running.  
General Service:  
1. Never run an engine indoors or in a poorly  
ventilated area. Engine exhaust contains carbon  
monoxide, an odorless and deadly gas.  
2. Before cleaning, repairing, or inspecting, make  
certain the trimmer head and all moving parts have  
stopped. Disconnect the spark plug wire and  
ground against the engine to prevent unintended  
starting.  
3. Check the trimmer head and engine mounting bolts  
at frequent intervals for proper tightness. Also,  
visually inspect trimmer head for damage. Replace  
with the original equipment manufacture’s (OEM)  
parts only, listed in this manual. “Use of parts which  
do not meet the original equipment specifications  
may lead to improper performance and  
compromise safety!”  
8. Never use other lengths, diameters, or materials as  
trimmer line. Doing so can result in personal injury.  
9. Trimmer head components, guards, and shields  
are subject to wear and damage which could  
expose moving parts or allow objects to be thrown.  
For safety protection, frequently check components  
and replace immediately with original equipment  
manufacturer’s (OEM) parts only, listed in this  
manual. “Use of parts which do not meet the  
original equipment specifications may lead to  
improper performance and compromise safety!”  
10. Do not change the engine governor setting or  
overspeed the engine.  
11. Maintain or replace safety and instruction labels, as  
necessary.  
12. Observe proper disposal laws and regulations.  
Improper disposal of fluids and materials can harm  
the environment.  
4. Keep all nuts, bolts, and screws tight to be sure the  
equipment is in safe working condition.  
5. Never tamper with safety devices. Check their  
proper operation regularly.  
6. After striking a foreign object, stop the engine,

objects being thrown into the eyes, which  
can cause severe eye damage. Always  
wear safety glasses included with unit or  
eye shields when operating the string  
trimmer mower.  
NOTE: See your engine manual packed with your unit  
for more detailed instructions.  
WARNING: Never run the engine indoors  
or in a poorly ventilated area. Engine  
exhaust contains carbon monoxide, an  
odorless and deadly gas. Keep hands,  
feet, hair, and loose clothing away from  
the trimmer and engine.  
Gas And Oil Fill-Up  
WARNING: Do not attempt to bypass the  
control lever. Doing so could result in  
serious personal injury or death.  
Service the engine with gasoline and oil as instructed in  
the separate engine manual packed with your string  
trimmer mower. Read instructions carefully.

minutes after running.  
Using Your String Trimmer Mower  
Once the engine is started, release the control lock  
bracket on the upper right hand side of the handle  
by pushing it to the right and squeeze the control  
handle against upper handle to engage spindle  
assembly.  
Starting Engine  
Attach spark plug wire to spark plug. Make certain  
the metal cap on the end of the spark plug is  
fastened securely over the metal tip on the spark  
plug. See separate engine operator’s manual.  
Before each use, remove any debris from the  
engine’s air intake screen on top of engine. Debris  
can cause engine to overheat.  
The string trimmer mower is designed with the spin-  
dle off-set to the left side. This allows the operator  
to trim along a fence, landscaping, or a house with-  
out having to make any adjustments to the spindle  
assembly.  
If the weeds or grass are tall and thick, operate the  
string trimmer mower at a slower walking speed.  
With the engine off and spark plug disconnected,  
clean the underside of the trimmer before and after  
each use to remove any grass or weed build up.  
If the trimmer lines become too short, approxi-  
mately half the original length, or worn, it will take  
longer to complete the job. To change to a new  
trimmer line see MAINTAINING YOUR STRING  
TRIMMER MOWER.  
Prime engine as instructed in the separate engine  
manual packed with your unit.

RUN position.  
Make sure control lever is disengaged and locked  
in bracket.  
Stand behind the string trimmer mower and grasp  
starter handle and pull rope out slowly until engine  
reaches start of compression cycle (rope will pull  
slightly harder at this point). Let the rope rewind  
slowly. Pull rope with a rapid, continuous, full arm  
stroke. Keeping a firm grip on the starter handle, let  
the rope return to the starter slowly. Repeat until  
engine starts.  
Do not trim on excessively steep slopes. If a slope  
is difficult to stand on, do not trim. Do not trim on  
slopes when the ground is slippery or wet. Trim  
across the face of a slope, not up and down.  
Avoid spindle assembly contact to concrete,  
asphalt, or gravel.
