cause loss of control.
WARNING
Do not operate the throttle trigger with your left hand
and hold the front handle with your right hand. Never
allow any part of your body to be in the chain line while
operating a saw.
PUSH AND PULL
See gure 19.
The reaction force is always opposite to the direction the
chain is moving. Thus, the operator must be ready to
control the pull (A) when cutting on the bottom edge of
the bar and the push (B) when cutting along the top edge.
NOTE: Your chainsaw has been fully factory tested. It is
normal to nd some slight lubricant residue on the saw.
PROPER CUTTING STANCE
See gure 20.
Balance your weight with both feet on solid ground.
Keep left arm with elbow locked in a "straight arm"
position (B) to withstand any kick-back force.
Keep your body to the left of the chain line (A).
Keep your thumb on underside of handlebar (C).
BASIC OPERATING/CUTTING PROCEDURES
Practise cutting a few small logs using the following
technique to get the "feel" of using your saw before you
begin a major sawing operation.
1. Take the proper stance in front of the wood with the
saw idling.
2. Accelerate the engine to full throttle just before
entering the cut by squeezing the throttle trigger.
3. Begin cutting with the saw against the log.
4. Keep the engine at full throttle the entire time you are
cutting.
5. Allow the chain to cut for you; exert only light downward
pressure. Forcing the cut could result in damage to the
bar, chain, or engine.
6. Release the throttle trigger as soon as the cut is

7. Do not put pressure on the saw at the end of the cut.

WORK AREA PRECAUTIONS

See gure 21. See gure 27 - 28.

ADJUSTING THE CARBURETTOR

See gure 22. See gure 23 - 24.
Before adjusting the carburettor, clean the air lter (A) and
the starter cover vents (B). Allow the engine to warm up
prior to carburettor adjustment. Refer to "Maintenance"
later in this manual.
The carburettor is factory set and should not require
adjusting. The carburettor will permit only limited
adjustment of the "L" (Low Jet) and "H" (High Jet) needles.
Any adjustment should be done by a Ryobi service dealer.
Under no circumstances should the "L" (Low Jet) and
"H" (High Jet) needles be forced outside the range of
adjustment.
Serious damage may occur to the engine if improper
adjustments are made to the "L" and "H" needles. Do
not force the "L" and "H" needles outside the adjustment
range!

completed, allowing the engine to idle. Running the
saw at full throttle without a cutting load may result in
unnecessary wear to the chain, bar, and engine.
Cut only wood or materials made from wood; no sheet
metal, no plastics, no masonry, no non-wood building
materials.
Never allow children to operate your saw. Allow no
person to use this chainsaw who has not read this
operator's manual or received adequate instructions
for the safe and proper use of this chainsaw.
Keep everyone – helpers, bystanders, children, and
animals, a safe distance from the cutting area. During
felling operations, the safe distance should be at least
twice the height of the largest trees in the felling area.
During bucking operations, keep a minimum distance
of (4.5 m) 15 ft between workers.
Always cut with both feet on solid ground to prevent
being pulled off balance.
Do not cut above chest height as a saw held higher is
difficult to control against kick-back forces.
Do not fell trees near electrical wires or buildings.
Leave this operation for professionals.
Cut only when visibility and light are adequate for you
to see clearly.
