increase fuel consumption and make
starting more difficult.

noticeable loss of engine power:
: Press down the interlock lever and
squeeze throttle trigger at the same
time, set the Master Control lever to
cold starter position l.
: Turn the twist lock above the rear
handle 90° counterclockwise.

: Remove the filter upwards.
: Wash the filter in a clean, non-
flammable solution (e.g. warm
soapy water) and then dry.
Always replace a damaged filter.
: Reinstall the air filter.

Motor Management

Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components (e.g.
carburation, ignition, timing and valve or
port timing) without the addition of any
major hardware.
