GENERAL LUBRICATION

IMPORTANT: Wipe each fitting clean before and after lubrication. Do not wipe gearcase filler plug; wiping the gearcase filler plug may remove thread sealant and cause leaks.

IMPORTANT: DO NOT allow grease or oil to get on friction disc, friction plate or belts.

NOTE: Apply Ariens Hi-Temp Grease or equivalent to the lubrication fittings. See SERVICE PARTS on page 35.

Sno-Thro should be lubricated (Figure 23) at beginning of season or every 25 operating hours.
