Working Techniques - Craftsman 358.740160 Manual Del Operador

NOTE: If the product does not restart, the
problem could be overheated fuel.
To fix this problem, try the following procedure:
1. Set the product in a cool area away from
direct sunlight.
2. Allow the product to cool for at least 20
minutes.
3. Press primer (air purge) bulb repeatedly for
10-15 seconds.
4. Follow the cold starting procedure.
Repeat this procedure if the problem still exists.
NOTE: Always use fresh seasonal fuel and
shorten operation time during unseasonably
warm weather.
Starting A Flooded Engine
The engine may be flooded with too much fuel
if it has not started after 10 pulls.
Flooded engines can be restarted by pushing
the blue choke lever in completely to the OFF
CHOKE position and then following the warm
engine starting procedure listed above. Ensure
the red ON/STOP switch is in the ON position.
Starting could require pulling the starter rope
handle many times depending on how badly
the unit is flooded. If the engine fails to start,
refer to the TROUBLESHOOTING TABLE or
call the consumer assistance help line.
CHAIN TENSION
It is normal for a new chain to stretch during the
first 15 minutes of operation. You should check
your chain tension each time before you start
the chainsaw. See the chain tensioning
instructions in the ASSEMBLY section.
WARNING: If the saw is operated
with a loose chain, the chain could jump
off the guide bar and result in serious
injury to the operator and/or damage the
chain, making it unusable.
PRACTICING YOUR CUTS
Practice cutting a few small logs using the
following techniques to get the "feel" of using
your saw before you begin a major sawing
operation.
Squeeze the throttle trigger and allow the

engine to reach full speed before cutting.
Begin cutting with the saw frame against the

log.
Keep the engine at full speed the entire time

you are cutting.
Allow the chain to cut for you. Exert only light

downward pressure. If you force the cut,
damage to the guide bar, chain, or engine
can result.

CHECKING THE CHAIN BRAKE
The chain brake must be checked before each
use. The engine must be running when
performing this procedure.
This is the only instance when the saw should
be placed on the ground with the engine
running.
1. Place the saw on firm ground.
2. Grip the rear handle with your right hand
and the front handle with your left hand.
3. Apply full throttle by fully depressing the
throttle trigger.
4. Activate the chain by turning your left wrist
to contact the front hand guard without
releasing your grip around the front handle.
The chain should stop immediately.
CHECKING THE INERTIA ACTIVATING
FUNCTION CONTROL
WARNING: When performing the
following procedure, the engine must be
turned off.
1. Grip the rear handle with your right hand
and the front handle with your left hand.
2. Hold the chainsaw approximately 16-18
inches (40-45 centimeters) above a stump
or other wooden surface.
3. Release your grip on the front handle and
use the weight of the saw to let the tip of the
guide bar fall forward and contact the stump.
When the tip of the bar hits the stump, the
brake should activate as observed by the
front hand guard snapping forward toward
the guide bar.
Release the throttle trigger as soon as the cut

is completed, allowing the engine to idle. If
you run the saw at full throttle without a
cutting load, unnecessary wear can occur to
the chain, guide bar, and engine. It is
recommended that the engine not be
operated for longer than 30 seconds at full
throttle.
To avoid losing control when cut is complete,

do not put pressure on saw at end of cut.
Stop the engine before setting the saw down

after cutting.
