Muffler; Air FIlter; Spark Plug - McCulloch CS 410 Manual De Instrucciones

Throttle lockout
• Make sure the throttle control is locked at the idle
setting when the throttle lockout is released.
• Press the throttle lockout and make sure it returns to
its original position when you release it.
• Check that the throttle trigger and throttle lockout
move freely and that the return springs work properly.
• Start the chain saw and apply full throttle. Release the
throttle control and check that the chain stops and
remains stationary. If the chain rotates when the
throttle control is in the idle position you should check
the carburetor idle adjustment.
Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw.
Right hand guard
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks.
Vibration damping system
Regularly check the vibration damping units for cracks or
deformation.
Make sure the vibration damping units are securely
attached to the engine unit and handle unit.
Stop switch
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting. (29)
CAUTION! The start/stop switch automatically returns to
run position. To avoid involuntary start up, the spark plug
cap must always be removed from the spark plug when
the machine is unsupervised. (30)
MAINTENANCE
Muffler
Never use a machine that has a faulty muffler. Regularly
check that the muffler is securely attached to the machine.
Note: The spark arrestor screen (A) on this machine is
serviceable. The screen must be replaced if it is
damaged. If the screen is blocked the machine will
overheat and this will cause damage to the cylinder and
piston. Never use a machine with a muffler that is in poor
condition. Never use a muffler if the spark arrestor
screen is missing or defective. (7)
After 75 hours of use, we recommend that your muffler be
replaced by your servicing dealer (retailer).
Air filter
The air filter must be regularly cleaned to remove dust and
dirt in order to avoid:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts
• Excessive fuel consumption.
• Remove the air filter after taking off the air filter cover.
When refitting make sure that the air filter seals tightly
against the filter holder. Clean the filter by brushing or
shaking it. (44)
The filter can be cleaned more thoroughly by washing it in
water and detergent.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.

Spark plug

The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type of
oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
