WARNING: Stop engine, remove key
and wait for moving parts to stop before
attempting
any lubrication or
maintenance procedures.
CAUTION: DO NOT touch engine or
Sno-Thro drive parts which are hot from
operation.
Allow such parts to cool
before servicing unit.
Engine Cooling
Engine is air cooled. Air must circulate freely around
engine from air intake screen, over cooling fins on
cylinder head and block, to prevent overheating.
Every 100 operating hours or yearly (more often if
conditions require) remove cooling shrouds and clean
cooling fins. Also clean external surfaces of engine
of dust, dirt and oil deposits which can contribute to
improper cooling.
IMPORTANT: DO NOT operate engine with cooling
shrouds removed, this will cause overheating and
engine damage.
