Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.

noticeable loss of engine power:

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.
: Lift off the shroud vertically.
: 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.
