Assembly / Installation

Lubrication and Oil

CAUTION Do not attempt to operate this air compressor without first verifying the oil level in the crankcase. This compressor is shipped with oil in the crankcase. Serious damage of the compressor can result from even momentary operation without proper lubrication.

Prior to each use, verify the crankcase oil level. An oil sight gauge with minimum and maximum oil level marks is provided with this compressor.

Always verify that the oil level is at the maximum mark in the oil sight gauge before operating this unit. Do not operate the pump with an inadequate or excessive amount of oil. The cost of failures which occur due to incorrect oil levels will not be covered under warranty.

To check the oil level: (see Fig. 1)

1.Place unit on a level surface.

2.Remove dipstick, wipe with a clean rag, replace in crankcase, then remove dipstick to inspect oil level.

3.If oil level is low, add as required, but do not exceed maximum oil level.

CAUTION Do not allow particulates such as sawdusttofallintocrankcasewhen crank case is open for inspection. Particulates in oil

may reduce compressor life.

CAUTION Do not use a detergent oil in crankcase. Detergent oils will leave deposits on internal compressor components reducing compressor life and performance.

Grounding

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be inserted into an outlet that is properly installed and grounded in accordance with all local codes and ordinances (see Fig. 3).

WARNING Improper installation of the grounding plug is able to result in a risk of electric shock. When repair or replacement of the cord or plug is required, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

Check with a qualified electrician or serviceman

when the grounding instructions are not completely understood, or when in doubt as to whether the product is properly grounded. Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.
