Harbor Freight Tools 93874 To Add Compressor Oil, Sight Glass. See Figure B

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.)
