GENERAL SAFETY RULES

WARNING
Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury. SAVE THESE INSTRUCTIONS

WORK AREA
Keep your work area clean and well-lit. Cluttered benches and dark areas invite accidents. The floor must not be slippery from wax or dust. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite the dust or fumes. Keep bystanders, children, and visitors away while operating tools. Distractions can cause you to lose control. Operate the air compressor in an open area at least 18 in. away from any wall or object that could
restrict the flow of fresh air to ventilation openings.

ELECTRICAL SAFETY
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord. Never use the cord to carry the tool or pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY
Eye protection which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when loading, operating, or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. We recommend a Wide Vision Safety Mask for use over eyeglasses or standard safety glasses that protect against flying particles both from the front and side. Always use eye protection which is marked to comply with ANSI Z87.1. Additional safety protection will be required in some environments.

For example, the working area may be exposed to a noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided and used by the operator and others in the work area. Some environments will require the use of head protection equipment. When required, the employer and user must ensure that head protection marked to comply with ANSI Z89.1 is used.

Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tools while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. Dress properly. Do not wear loose clothing or jewelry. Contains long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. Do not overreach. Keep proper footing and balance
at all times.

Proper footing and balance enable better control of the tool in unexpected situations. Use safety equipment. Always wear eye protection. A dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Do not use it on a ladder or unstable support. Stable footing on a solid surface enables better control of the tool in unexpected situations.

TOOL USE AND CARE
Do not exceed the pressure rating of any component in the system. Protect material lines and airlines from damage or puncture. Keep the hose and power cord away from sharp objects, chemical spills, oil, solvents, and wet floors.

Check hoses for weak or worn conditions before each use, making certain all connections are secure. Do not use it if a defect is found. Purchase a new hose or notify an authorized service center for examination or repair. Release the pressure within the system slowly. Dust and debris may be harmful. Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. Maintain tools with care. Follow maintenance instructions. Properly maintained tools are easier to control.

Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. Never point any tool toward yourself or others. Keep the exterior of the air compressor dry, clean, and free from oil and grease. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any strong solvents to clean the unit.

SAVE THESE INSTRUCTIONS

ELECTRICAL

EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the air compressor’s plug. When using the air compressor at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the compressor will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Laboratories (UL) should be used. When working with the air compressor outdoors, use an extension cord that is designed for outside use. This is indicated by the letters “WA” on the cord’s jacket. Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.

WARNING
Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury.

WARNING
Check extension cords before each use. If damaged, replace immediately. Never use an air compressor with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury. NOTE: Use longer air hoses instead of long extension cords. Your air compressor will run better and last longer.

ELECTRICAL CONNECTION

This air compressor is powered by a precision-built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the air compressor does not operate when plugged into an outlet, double-check the power supply.

SPEED AND WIRING
The no-load speed of the electric motor varies by model and specification. The motor speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor’s horsepower rating. A line intended only for lights cannot properly carry a power tool motor. The wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three tools.

GROUNDING INSTRUCTIONS
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 air compressor is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded by all local codes and ordinances. Do not modify the plug provided. If it does not fit the outlet, have the proper outlet installed by a qualified electrician.

WARNING
Improper connection of the equipment-grounding the conductor can result in a risk of electric shock. The conductor with insulation has an outer surface that is green with or without yellow stripes the equipment- grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment- grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Repair or replace a damaged or worn cord immediately. This product is for use on a nominal 120-V circuit and has a grounding plug similar to the plug illustrated in Figure 1. Only connect the product to an outlet having the same configuration as the plug. Do not use an adapter with this product. Never use an electrical adaptor with this grounded plug.

Pull the ring on the safety valve to release air for twenty seconds.
Release the ring. Air must immediately stop escaping when the ring is released.
Any continued loss of air after releasing the safety valve ring indicates a problem with the safety valve.
Discontinue use and seek service before continued use of the air compressor.

WARNING
If air leaks after the ring has been released, or if the valve is stuck and cannot be actuated by the ring, Do Not use the air compressor until the safety valve has been replaced. Use of the air compressor in this condition could result in serious personal injury.

MAINTENANCE

WARNING
When servicing, use only identical Harbor Freight Tools replacement parts. Use of any other parts may create a hazard or cause product damage.

WARNING
Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If the operation is dusty, also wear a dust mask.

WARNING
Always release all pressure, disconnect from the power supply, and allow the unit to cool to the touch before

GENERAL MAINTENANCE
Humidity in the air causes condensate to form in the air tank. This condensate should be drained daily and/or every hour, using the instructions found in Draining the Tank. The safety valve automatically releases air if the air receiver pressure exceeds the preset maximum. Check the safety valve before each use following the instructions found in Checking the Safety Valve. Inspect the tank yearly for rust, pinholes, or other imperfections that could cause it to become unsafe. Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.

WARNING
Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken, or destroy plastic which may result in serious personal injury. Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.

CHECK THE OIL LEVEL AT REGULAR INTERVALS
See Figure 11. Place the compressor on a level and straight surface. The oil level must be between the two marks MAX and MIN on the oil sight glass (fig. 11). Changing the oil: use SAE 40 oil (for cold climates, SAE 20 is recommended). Do not mix different-grade oils. If the oil changes color (whitish = presence of water; dark = overheated), it is good practice to replace the oil immediately. It should be refilled for the first time after 100 hours of operation. Thereafter the oil should be drained and refilled every 300 hours in service.

CHANGING THE OIL
See Figures 11 – 12.
Switch off the engine and pull the mains plug out of the socket. After releasing any air pressure you can unscrew the oil drain plug (fig. 11) from the compressor pump. To prevent the oil from running out in an uncontrolled manner, hold a small metal chute under the opening and collect the oil in a vessel. If the oil does not drain out completely, we recommend tilting the compressor slightly. Dispose of the old oil at a drop-off point for old oil.

When the oil has drained out, re-fit the oil drain plug (fig. Fill new oil through the oil filler opening until it comes up to the required level. Do not overfill. After topping up, tighten the oil fill plug (fig. 12), making sure that there are no leaks during use. Once a week, check the oil level to ensure proper lubrication.

RETENSIONING THE V-BELT
See Figures 13 – 15.

Pull out the power plug and remove the safety guard for the V-belt (figures 13 – 14). Slacken the four motor fixing screws (figure 15). Shift the motor until the V-belt is tensioned to the point where it can still be depressed by approx. 0.4-0.8 in. (1-2 cm) at the longest free position. Retighten the motor fixing screws and refit the safety guard for the V-belt.

TIGHTENING OF HEAD TENSION RODS
See Figure 16.
Check that all screws (in particular those of the head of the unit) are tightly drawn up. The check must be carried out before the first compressor starts. And after the first hour of work.

Tightening values for the tension rods of the head:

Nm min. torque = 22
Nm max. torque = 27

CLEANING THE INTAKE FILTER

See Figure 17.

The intake filter prevents dust and dirt from being drawn in. It is essential to clean this filter after at least every 100 hours in service. A clogged intake filter will decrease the compressor’s performance dramatically. Undo the two allen screws. You can then remove the filter from the two halves of the plastic housing, tap it to remove the dirt, blast it down with low- pressure compressed air (approx. 3 bar), and re-insert it.
