SPECIFIC SAFETY RULES

 

FUEL SAFETY

 

• 

 

Handle fuel with care; it is highly flammable. 

• 

 

Use an approved container. 

• 

 

Check fuel supply before each use, allowing space for

expansion as the heat of the engine and/or sun can cause

fuel to expand.

• 

 

Fill fuel tank outdoors with extreme care.  Never fill fuel  

tank indoors. 

• 

 

Never remove gas cap or add fuel with the engine running.

Allow engine to cool before refueling.

• 

 

Do not smoke while refueling.

• 

 

After refueling, replace fuel tank cap securely and wipe up

spilled fuel.

• 

 

Never store fuel or trimmer with fuel in the tank inside a 

building where fumes may reach an open flame. 

STORAGE SAFETY

 

• 

 

Always refer to the operator’s manual instructions for

important details if the trimmer is to be stored for an

extended period.

• 

 

Never store the trimmer with fuel in the fuel tank inside a 

building where ignition sources are present such as water

heaters, space heaters, clothes dryers, etc.

• 

 

To reduce fire hazard, keep trimmer free of grass, leaves,  

or other debris build-up.

• 

 

Allow the engine to cool before storing in any enclosure. 

REPAIR, MAINTAINANCE, AND ADJUSTMENT 
SAFETY

 

• 

 

After striking a foreign object, stop the engine.  Remove 

the wire from the spark plug and keep the wire away from

the plug to prevent accidental starting.  Thoroughly inspect

the trimmer for any damage.  If damaged, have the

equipment repaired by a trained technician before

restarting and operating.

• 

 

Stop the engine before cleaning, repairing, or inspecting

the unit.  Make sure all moving parts have stopped.  Let 

the engine cool, disconnect the spark plug wire and move

it away from the spark plug.

• 

 

Never attempt to make any adjustments while the engine 

Page 3

 

is running except when specifically recommended by the  

manufacturer. 

• 

 

Keep the trimmer in safe working condition.  Check all 

fasteners at frequent intervals for proper tightness.

• 

 

When servicing or repairing the trimmer, do not tip the  

machine over or up unless specifically instructed to do so 

in this Manual.  Service and repair procedures can be

done with the trimmer in an upright position.  Some 

procedures will be easier if the machine is lifted on a

raised platform or working surface.

• 

 

Use only original equipment or authorized replacement 

parts.

• 

 

Never tamper with safety devices.  Check their proper

operation regularly. 

• 

 

Do not change the engine governor setting or over-speed

engine.

• 

 

Clean and replace safety and instruction decals as 

necessary. 

• 

 

To guard against engine over-heating, always have engine 

debris filter mounted and clean. 

CHILDREN SAFETY

 

• 

 

Tragic accidents can occur if the operator is not alert to the 

presence of children. Children are often attracted to the

trimmer and the trimming activity.  

• 

 

Keep children out of the trimming area and under the

watchful care of a responsible adult.

• 

 

Never assume that children will remain where you last saw

them. 

• 

 

Be alert and turn trimmer off if children enter the area. 

• 

 

Before and while moving backwards, look behind and

down for small children. 

• 

 

Never allow children to operate the trimmer. 

• 

 

Use extra care when operating near blind corners, shrubs,

trees, or other objects that may obstruct vision.
