SPECIFIC SAFETY RULES
PROPER CLOTHING FOR SAFETY
■
Wear close-fitting clothing. Always wear heavy, long
trousers, boots, and gloves. Do not wear jewellery,
shorts, sandals, or go barefoot. Do not wear loose-
fitting clothing, which could be drawn into the engine
or catch the chain or undergrowth. Wear overalls,
jeans, or leggings made of cut-resistant material or
ones that contain cut-resistant inserts. Secure hair so
that it is above shoulder level.
■
Wear non-slip safety footwear and heavy-duty gloves
to improve your grip and to protect your hands.
■
Wear eye, hearing, and head protection when
operating this equipment.
REFUELLING (DO NOT SMOKE!)
■
To reduce the risk of fire and burn injury, handle fuel
with care. It is highly flammable.
■
Mix and store fuel in a container approved for petrol.
■
Mix fuel outdoors where there are no sparks or flames.
■
Select bare ground, stop the engine, and allow it to
cool before refuelling.
■
Loosen the fuel cap slowly to release pressure and to
keep fuel from escaping around the cap.
■
Tighten the fuel cap securely after refuelling.
■
Wipe spilled fuel from the unit. Move 15 m (50 ft.)
away from refuelling site before starting engine.
■
Never attempt to burn off spilled fuel under any
circumstances.
BASIC PRECAUTIONS IN THE CUTTING/
WORK AREA
■
Do not operate a chainsaw in a tree.
■
Do not cut from a ladder: this is extremely dangerous.
■
Keep bystanders and animals out of the work area.
Do not allow other persons to be nearby during
starting or cutting with the chainsaw.
NOTE: The size of the work area depends on the job
being performed as well as the size tree or workpiece
involved. For example, felling a tree requires a
larger work area than making other cuts, i.e. bucking
cuts etc.
PUSH AND PULL
The reaction force is always opposite to the direction the
chain is moving. Thus, the operator must be ready to
control the PULL when cutting on the bottom edge of the
bar and the PUSH when cutting along the top edge.
NOTE: Your chainsaw has been fully factory tested.
It is normal to find some slight oil residue on the saw.
MAINTENANCE PRECAUTIONS
Never operate a chainsaw that is damaged, improperly
adjusted, or is not completely and securely assembled.
Be sure that the saw chain stops moving when the throttle
control trigger is released. If the saw chain moves at idling
speed, the carburettor may need adjusting. Refer to
“Operation-Adjusting Idling Speed” later in this manual.
If the saw chain still moves at idling speed after adjustment
has been made, contact a Ryobi service dealer for
adjustment and discontinue use until the repair is made.
WARNING
All chainsaw service, other than items in the
operator’s manual maintenance instructions,
should be performed by competent chainsaw
service personnel. If improper tools are used to
remove the flywheel or clutch, or if an improper
tool is used to hold the flywheel in order to remove
the clutch, structural damage to the flywheel could
occur which could subsequently cause the
flywheel to burst and serious injury could result.
KICK-BACK
Kick-back is a dangerous reaction that can lead to
serious injury. Do not rely only on the safety devices
provided with your saw. As a chainsaw user, you must
take special safety precautions to help keep your cutting
jobs free from accident or injury.
NOTE: Refer to “Operation” later in this manual for added
information on kick-back and how to avoid serious
personal injury.
