To Add Compressor Oil:
1. IMPORTANT! Prior to first using the Compressor, the Compressor MUST be
filled with a high quality 30 weight, non-detergent, compressor oil.
(See Figure B.)
2. To do so, remove the red plastic plug that is covering the oil fill hole. That plastic
plug is only used for shipping purposes. Pour approximately 1/2 quart of compres-
sor oil into the Compressor Oil Plug Hole. Do not overfill. (See Figure B.)
3. Observe the level of compressor oil through the Compressor’s Oil Level Sight
Glass (21A). The oil level should be maintained at the center dot in the sight
glass. (See Figure B.)
4. If necessary, continue adding compressor oil, while rechecking the Compressor’s
Oil Level Sight Glass (21A), until the oil level reaches the “MAXIMUM” mark on
the Indicator. Do not exceed the “MAXIMUM” indicator mark on the Oil Level
Sight Glass. (See Figure B.)
5. When finished adding compressor oil, install the Oil Breather Plug (37A) into the
Compressor Oil Plug Hole. The Oil Breather Plug is press-fitted in with the flat
edge of the plug facing the cylinder. The large O-rings on top serve as a grip when
removing it. (See Figure B.)
