Warme

SAE 30

Oil Viscosity Chert

NOTE: Although multi-viscosity oils (5W30, IOW30,
etc.) improve starting in cold weather, they will result
in increased oil consumption when used above 32°F.
Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Remove oil fill dipstick.
With the Yard Vacuum on level ground, use a
funnel to'fill engine with oil to FULL mark on
dipstick. Capacity is approximately 20 oz. Be
careful not to overfill. Overfilling will cause the
engine to smoke profusely and will result in poor
engine performance. The oil bottle packaged
with your Yard Vacuum contains 20 oz. of oil.
•
Check the oil level making certain not to rub the
dipstick along the inside walls of the oil fill tube.
This would result in a false dipstick reading. Refill
to FULL mark on dipstick, if necessary. Replace
dipstick and tighten.
•
Check oil level three times prior to starting engine
to be certain you've gotten an accurate dipstick
reading. Running the engine with too little oil can
result in permanent engine damage.

If you have drained the fuel tank, protect the inside of
the engine as follows:

IMPORTANT:It is important to prevent gum deposits
from forming in essential fuel system parts such as
the carburetor, fuel filter, fuel hose, or tank during
storage. Also, alcohol blended fuels (called gasohol or
using ethan_'or methanol) can attract moisture which
leads to separation and formation of acids during
storage. Acidic gas can damage the fuel system of an
engine while in storage.
