ENGINE MAINTENANCE

IGNITION.
Your engine has a breaker-less solid state
ignition system which requires no mainte-
nance other than occasional attention to
the spark plug. We recommend cleaning
and re-gapping every 50 hours, with
replacement every 100 hours. (See engine
instruction booklet).
CAUTION
DO NOT SANDBLAST PLUGS as abrasive
grains can enter the engine and cause serious
damage. USE ONLY THE EXACT TYPE OF
REPLACEMENT PLUG specified in the engine
instruction booklet.
AIR CLEANER.
A clean filter cartridge, correctly fitted, is
ESSENTIAL for long engine life. Service
the filter every 25 hours running (more
often under adverse conditions) according
to the instructions in the engine booklet.
MUFFLER.
A rusted or damaged muffler can permit
increased exhaust noise. Check the muffler
condition periodically and replace it only with
a genuine original equipment part.

The gearbox on these models is a sealed unit
that requires no maintenance. Just keep the

the bottom of the gearbox towards you to
apply tension to the drive belt. Retighten the
nut and screw. (R/H view when looking at
