BREAK-IN PROCEDURES

Location of the Air Compressor

Operate the air compressor in a clean, dry and well ventilated area. The fan bladed flywheel must be kept clear of obstructions that could interfere with the flow of air through the air intake filter. The pump crankcase and head are designed with fins to provide proper cooling.

If humidity is high, an air filter can be installed on the air outlet adapter to remove excessive moisture. Closely follow the instructions packaged with the filter for proper installation. It must be installed as close as possible to the accessory.Do not place the air compressor where heat is excessive.

When locating the compressor outside, make sure there is a mimum of 12 inches on each side of the compres- sor. There must be fresh air flow for proper cooling. DO

NOT ALLOW THE COMPRESSOR TO GET WET.

Lubrication and Oil

Compressors are shipped without oil. Do not attempt to operate this air compressor without first adding oil to the crankcase. Serious damage can result from even limited operation unless filled with oil and broken in correctly. Make sure to closely follow initial start-up procedures.

Place unit on a level surface. Remove oil fill plug and slowly add a special compressor oil such as Sears 9-16426 or SAE 20-20W SF motor oil until it is even with the top of the oil fill hole. (It must not be allowed to be lower than 3/8" -- 6 threads down -- from the top at any time.) When filling the crankcase, the oil flows very slowly. If the oil is added too quickly, it will overflow and appear to be full. Crankcase oil capacity is 16 fluid ounces. Under winter-type conditions use SAE 10W oil. Multi-viscosity oil, 10W 30, will leave carbon deposits on critical components, reducing perfor- mance and compressor life. Replace oil fill plug.

NOTE

Drain and refill the compressor pump crank- case after the first 100 hours of operation.

GROUNDING INSTRUCTIONS

RISK OF ELECTRICAL SHOCK. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.

This portable air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be used with an outlet that has

been installed and grounded in accordance with all local codes and ordinances. The outlet must have the same configuration as the plug. DO NOT USE AN

ADAPTER.

Inspect the plug and cord before each use. Do not use if there are signs of damage.

IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.

Do not modify the plug that has been provided. If it does not fit the available outlet, the correct outlet should be installed by a qualified technician.

If repairing or replacing cord or plug, the grounding wire must be kept separate from the current-carrying wires. Never connect the grounding wire to a flat blade plug terminal. The grounding wire has insulation with an outer surface that is green with or without yellow stripes.

If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualified electrician.

Voltage and Circuit Protection

Refer to your Specification Chart (page 6) for voltage and circuit protection requirements of your compressor. Use only a fuse or circuit breaker that is the same rating as the branch circuit the air compressor is operated on. If the compressor is connected to a circuit protected by fuses, use only dual element time delay fuses.
