Receipt and Inspection

Before signing the delivery receipt, inspect for damage and missing parts.

If damage or missing parts are apparent, make the appropriate notation on the delivery receipt, then sign the receipt. Immediately contact the carrier for an inspection. All material must be held in the receiving location for the carrier’s inspection. Delivery receipts that have been signed without a notation of damage or missing parts are considered to be delivered “clear.” Subsequent claims are then considered to be concealed damage claims. Settle damage claims directly with the transportation company.

If you discover damage after receiving the air compressor (concealed damage), the carrier must be notified within 15 days of receipt and an inspection must be requested by telephone with confirmation in writing.

On concealed damage claims, the burden of establishing that the compressor was damaged in transit reverts back to the claimant. Read the compressor nameplate to verify it is the model ordered, and read the motor nameplate to verify it is compatible with your electrical conditions.

Make sure electrical enclosures and components are appropriate.

installation

& grounding

Installation and Location

The compressor must be used on a stable level surface. The air compressor must be used in a clean and well-ventilated area. The compressor requires an unobstructed airflow and must be located a minimum of 18 inches from any walls or other obstructions.

Grounding Instructions

This product should 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 plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

DANGER

ELECTRIC SHOCK:

Improper installation of the grounding plug can result in a risk of electric shock. If repair or replacement of the cord is necessary, 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.

This product is for use on a nominal 120-volt circuit and has a threeprong grounding plug that looks like the plug illustrated in Figure 1. Make sure that the product is connected to an outlet having the same configuration as the plug. No adapter could be used with this product.

The use of a GFCI outlet is strongly recommended. The third prong is to be used ground the tool and provide protection against electrical shock. Never remove the third prong.

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

Extension Cords

We do not recommend the use on an extension cord with this product as this may result in the loss of power and overheating of the motor. An additional air hose should be used instead of an extension cord. However, if the use of an extension cord is unavoidable, use only UL listed wire extension cords that have three-pronged grounding type plugs and three prong receptacles that accept the tool’s plug. Improper use of extension cords may cause inefficient operation of you tool, which can result an overheating.

Be sure your extension cord is rated to allow sufficient flow to motor.

Refer to the guide for minimum gauge required for extension cords.

Extension Cord Length

Up to 25 Feet

26 to 50 Feet

51 to 100 Feet

Wire Size (A.W.C.)

14

12

10

Use of an extension cord heavy enough to carry the current the tool will draw is very important. Especially when the power source is of great distance. An extension cord that is insufficient will cause a drop in line voltage, resulting in power loss and causing the motor to overheat.

Guard against electrical shock. Avoid body contact with grounded services such as pipes, radiators, ovens, stoves, and refrigerator enclosures.

If not properly grounded, this power tool can incur the potential hazard of light trickle shock, particularly when used in damp locations. If an electrical shock occurs, there is the potential of a secondary hazard such as your hands contacting an operating air tool.
