Lubrication and Maintenance

Ariens Dealers will provide any service which may be

required to keep your Sno-Thro operating at peak

efficiency. Should engine service be required, it can

be obtained from an Ariens dealer or an authorized

engine manufacturer's service center.

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.

Drive Belts

WARNING: Gasoline is highly

flammable and its vapors are explosive.

Handle with care. Never allow smoking

materials, sparks or flame (match, pilot

light, etc.) near equipment or fuel

container.

CAUTION: When unit is tipped up onto

housing, remove enough fuel so that no

spillage will occur.
