Engine and Headlight

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, wait

for moving parts to stop and remove wire

from spark plug (keep wire away from

spark plug to prevent accidental starting)

before any lubrication or maintenance

procedures.

CAUTION: DO NOT touch engine or Sno-

Thro drive parts which are hot from opera

tion. Allow such parts to cool before ser

vicing unit.

9.1 Engine Oil

Checking

The engine crankcase oil should be checked daily or

every 5 hours of operation. Oil level MUST be

maintained in safe operating range on dipstick at

all times or engine damage will result.

To check oil, park Sno-Thro on a flat level surface.

Wipe all debris from around dipstick, remove it and

wipe oil off. Screw dipstick assembly firmly but

slowly until cap bottoms on tube. Remove dipstick

and observe oil level. If low add clean fresh oil, of

same type and viscosity as is in engine, to bring oil

level to Full (F) mark (per engine manufacturer's

instructions).

IMPORTANT: DO NOT overfill. Level must not

exceed full (F) mark.

Changing

IMPORTANT: Change oil after first 5 hours of oper

ation, thereafter change oil every 25 hours of opera

tion (more often in dusty, dirty conditions). See

Engine Manufacturer's Instructions for proper type,

viscosity and amount required.

NOTE: Run engine just prior to changing oil. Oil

will flow more freely and carry away more conta

mination when warm.

Drain crankcase by removing oil drain plug (open

petcock on ST 1136). When oil has drained replace

plug (close petcock on AT 1136) and refill engine

crankcase with new oil of proper grade (per engine

manufacturer's instructions). Recheck oil level with

dipstick.

9.2 Engine Cooling

The engine is air cooled. Air must circulate freely

around engine from air intake screen, over cooling

fins on cylinder head and block to prevent over

heating.

Every 100 operating hours or yearly (more often if

conditions require) remove cooling shrouds and

clean cooling fins. Also clean external surfaces of

your 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.

Fill crankcase with oil as recommended below.

Refer also to Engine Manufacturer's Instructions

supplied with the product. Check oil level before

each use and change oil regularly according to

Engine Manufacturer's Instructions.
