residual water from the exhaust
system by alternately pushing the
throttle lever up to half throttle and
back for 10 to 15 seconds. Shut off

could flow back through the muffler
into the crankcase causing severe
engine damage. Do not run the engine
for more than 15 seconds after the
water supply has been turned off to
avoid engine overheating.
