Stihl MS 311 Manual De Instrucciones página 10

English
For proper assembly of the bar and saw
chain follow the procedure described in
the chapter "Mounting the Bar and
Chain" of your instruction manual.
STIHL Oilomatic saw chain, guide bar
and sprocket must match each other in
gauge and pitch. Before replacing any
bar and chain, see the chapter entitled
"Specifications" in the instruction
manual and the chapter "Reactive
Forces including Kickback".
Since longer bars add weight and may
be more difficult to control, select the
shortest bar that will meet your cutting
needs.
WARNING
Proper tension of the chain is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your
manual. Always make sure the
hexagonal nut(s) for the sprocket cover
is (are) tightened securely after
tensioning the saw chain in order to
secure the bar. Never start the chain
saw with the sprocket cover loose.
Check chain tension once more after
having tightened the nut(s) and
thereafter at regular intervals (whenever
the saw is shut off). If the saw chain
becomes loose while cutting, shut off the
engine and then tighten. Never try to
adjust the saw chain while the engine is
running!
WARNING
After adjusting a saw chain, start the
chain saw, let the engine run for a while,
then switch engine off and recheck saw
chain tension. Proper saw chain tension
is very important at all times.

Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your chain saw .
WARNING
Be sure that the guide bar and saw chain
are clear of you and all other
obstructions and objects, including the
ground. If the upper quadrant of the tip of
the bar touches any object, it may cause
kickback to occur (see section on
reactive forces). Never attempt to start
the chain saw when the guide bar is in a
cut or kerf.
For specific starting instructions, see the
appropriate section of your instruction
manual.
Starting
WARNING
To reduce the risk of fire and burn
injuries, start the engine at least 10 feet
(3 m) from the fueling spot, outdoors
only.
Start and operate your chain saw
without assistance. For specific starting
instructions, see the appropriate section
of the instruction manual. Proper starting
methods reduce the risk of injury.
WARNING
To reduce the risk of injury from saw
chain contact and / or reactive forces,
the chain brake must be engaged when
starting the chain saw. If your chain saw
is equipped with the Quickstop Plus
chain brake system, it is not sufficient to
engage that brake only for starting,
because the saw chain may begin to
rotate at high speed when the throttle
trigger lockout is depressed (releasing
the brake) in order to blip the throttle
trigger after starting.
WARNING
Do not drop start. This method is very
dangerous because you may lose
control of the chain saw.
There are two recommended methods
for starting your chain saw.
With the first recommended method, the
chain saw is started on the ground.
Make sure the chain brake is engaged
(see "Chain Brake" chapter in your
instruction manual) and place the chain
saw on firm ground or other solid surface
in an open area. Maintain good balance
and secure footing.
Grip the front handlebar of the saw firmly
with your left hand and press down. For
saws with a rear handle level with the
ground, put the toe of your right foot into
the rear handle and press down. With
your right hand pull out the starter grip
slowly until you feel a definite resistance
and then give it a brisk, strong pull.
