Stopping The Engine; Adjusting Idling Speed - Ryobi RCS4240B Mode D'emploi

CAUTION
Failure to release partial throttle when chain brake lever
is in the brake position will result in serious damage to
the unit. Never squeeze and hold the throttle trigger
while the chain brake is in the brake position.
TO START A WARM ENGINE:
■ Turn ignition switch to the ON position.
■ Make sure the chain brake is in the BRAKE position by
pushing forwards on the lever/hand guard.
■ Set the choke lever to "RUN" position.
■ Pull the starter grip with a quick firm and consistent
upward motion (no more than 5 times) until the engine
starts. If engine does not start, return to step 4 of "TO
START A COLD ENGINE" and repeat the steps.
■ Depress the trigger release. Squeeze and release
the throttle trigger to let the engine idle. Before
accelerating the engine or cutting wood: Make sure
the chain brake is in the run position by pulling back on
the lever/hand guard.

STOPPING THE ENGINE

See figure 7. See figure 14.
Release the throttle trigger and let the engine return to
idle. To stop the engine, move the ignition switch to the
"O" stop position. Do not put the chainsaw on the ground
when the chain is still moving. For additional safety, set
the chain brake when the saw is not in use.
In the event that the ignition switch will not stop the saw,
pull the choke lever out to the fully extended position (Full
Choke) and engage chain brake to stop the engine. If the
ignition switch will not stop the saw when set to the "O"
stop position, have the ignition switch repaired before
using the chainsaw again to prevent unsafe conditions or
serious injury.
NOTE: When you have finished using the saw, relieve
tank pressures by loosening the chain lubricant and fuel
mix caps. Allow the engine to cool before storing.

ADJUSTING IDLING SPEED

See figure 15.
■ If the engine starts, runs, and accelerates but will
not idle, turn the idling speed screw "T" clockwise to
increase idling speed.
■ If the chain turns at idle, turn the idling speed screw
"T" anticlockwise to reduce the idle RPM and stop the
chain movement. If the saw chain still moves at idling
speed, contact a Ryobi service dealer for adjustment
and discontinue use until the repair is made.
English (Original instructions)
The saw chain should never turn at idle. Serious
personal injury may result from the saw chain turning
at idle.
PUSH AND PULL
See figure 16.
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 lubricant residue on the saw.
KICK-BACK PRECAUTIONS
See figure 17 - 18.
Rotational kick-back occurs when the moving chain
contacts an object at the kick-back danger zone of the
guide bar. The result is a lightning-fast, reverse reaction
which kicks the guide bar up and back towards the
operator. This reaction can cause loss of control which
may result in serious injury.
PREPARING FOR CUTTING
PROPER GRIP ON HANDLES
See figure 19.
■ Wear non-slip gloves for maximum grip and protection.
■ Hold the saw firmly with both hands. Always keep your
Never use a left-handed (cross-handed) grip or any
stance that would place your body or arm across the
chain line.
■ Maintain a proper grip on the saw whenever the engine

left hand on the front handle and your right hand on
the rear handle so that your body is to the left of the
chain line.
WARNING
is running. The fingers should encircle the handle and
the thumb be wrapped under the handlebar. This grip
is least likely to be broken (by a kick-back or other
sudden reaction of the saw). Any grip in which the
thumb and fingers are on the same side of the handle
is dangerous because a slight kick of the saw can
cause loss of control.
