MAINTENANCE
Adjusting the start throttle speed
should clean the screen at least once a week.This is best
done with a wire brush.
The correct start throttle speed is set by means of an
adjuster on the rear of the handle next to the cable. Use
this screw (4 mm Allen screw) to increase or decrease the
start throttle speed.
On mufflers without a catalytic converter the screen
should be cleaned weekly, or replaced if necessary. On
mufflers fitted with a catalytic converter the screen should
be checked, and if necessary cleaned, monthly. If the
screen is damaged it should be replaced. If the screen
is frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired.
Contact your dealer to inspect the muffler. A blocked
screen will cause the machine to overheat and result in
damage to the cylinder and piston.
