Sears 176 Air Compressor User Manual


 
Chan_.;,=, v..
Overfilling with oil will cause premature
compressor failure. Do not overfill,
Check oil level in the crankcase before each use. The oil
level should be even with the top of the fillhole and must
not be allowed to be lower than _/8"from the top (6
threads down from the top) at any time. It is recom-
mended that the oil in the base (52) be changed after
every 100hours of operation. Todrain the oil,remove the
oil drain plug (51) and collect the oil in a Suitable con-
tainer. Be sure to replace the plug securely before
adding new oil. Use a special compressor oil, such as
Sears 9-16426 or SAE 20-20W SF motor oil (crankcase
oil capacity is 16 fluid ounces). Under extreme winter
conditions use SAE 10W oil,
Location of Air Compressor
Locate the unit in a dry, clean, cool and well ventilated
area. The compressor crankcase and head are
designed with fins which allow for proper cooling: Clean
or blow off fins and any other parts of the compressor
that collect dust Ordirt. A clean compressor runscooler
and provides longer service. Do not place rags, contain_
ers or other material on or against the console which
would obstruct ventilation openings necessary for prop:
er compressor operating temperature. If humidity is
high, a Sears Air Filter can be installed on the air outlet
adapter to remove excess moisture. Follow the instruc-
lions packaged with the air filter for proper installation.
