instructions listed below may result in electric shock, re and/or serious injury.
9 Save all warning and instructions for future reference.
1.2. WORK AREA SAFETY
9 Keep work area clean and well lit. Cluttered or dark area invites accidents.
8 DO NOT operate power tools in explosive atmospheres, such as in the presence of ammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
9 Keep children and bystanders away whilst operating a power tool. Distractions can cause you to lose control.
9 The concentration of processed gases that can displace breathing air shall be kept within acceptable levels.
1.3. ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following: You must check all
electrical products before use to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors for
wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A Residual
Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current Device
(RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not protected by an
RCCB. If in any doubt consult a qualified electrician. You must also read and understand the following instructions concerning electrical
safety:
1.3.1. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and
the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
9 Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
9 Ensure that cables are always protected against short circuit and overload.
9 Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none are loose.
Important: Ensure that the voltage marked on the appliance matches the power supply to be used and that the plug is fitted with the
correct fuse.
▲ DANGER! If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly
trained personnel.
8 DO NOT pull or carry the appliance by the power cable.
8 DO NOT pull the plug from the socket by the cable.
8 DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item repaired or replaced by a qualified electrician.
1.3.2. Over/current Protection: The user has to make provision for the installation of the over-current protection of the power circuit.
1.4. Electrical disconnecting device: The user has to make provisions for the installation of the electrical disconnecting device of the power

4. ASSEMBLY
4.1. UNPACKING THE COMPRESSOR
4.1.1. Unpack the air compressor unit. Inspect the unit for damaged. If the unit has been damaged, contact the retailer immediately.
4.1.2. Check the air compressor’s identication label to ensure that you have purchased the intended model and that it has the required
pressure rating for its intended use.
4.1.3. The carton should contain: (1) air compressor (2) owner’s manual.
4.2. POSITIONING THE COMPRESSOR
4.2.1. Locate the compressor in a clean, dry and well-ventilated area, on a rm level surface. It should be located 12” to 18” (30 to 45 cm)
from a wall or any other obstruction that would interfere with the air ow.
4.2.2. The compressor is equipped with heat dissipation vanes that allow for proper cooling. Keep them and other parts free of dust or dirt that could
interfere with cooling. A clean compressor runs cooler and provides longer service. DO NOT place anything on top of the compressor.
WARNING! DO NOT use lead-tin solder to join pipes and ttings. It can melt at the temperatures of the compressor’s air discharge and
cause the piping to burst.
5. OPERATION
WARNING! Ensure that you have read, understood and apply Section 1 safety instructions.
IMPORTANT! Use of extension leads to connect these compressors to the the mains is not recommended as the
resulting voltage drop reduces motor and therefore pump performance, and could damage the compressor.
NOTE: Take care when selecting tools for use with the compressor. Air tool manufacturers normally express the volume
of air required to operate a tool in cubic feet per minute(cfm).This refers to free air delivered by the compressor (‘air
out’) which varies according to the pressure setting.
8 DO NOT confuse this with the compressor displacement which is the air taken in by the compressor (‘air in’). ‘Air out’ is always less
than ‘air in’ due to losses within the compressor.
5.1. BEFORE EACH START UP
5.1.1. Set the ON/OFF switch (3) to the “o” position.
5.1.2. Turn the air pressure regulator (1) counterclockwise until it stops.
5.1.3. Attach air hose / accessories or air tools to the quick coupler (5).
WARNING! Risk of bursting: Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum air
pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating.
5.2. HOW TO START UP
5.2.1. Close the drain valve (7) by turning clockwise.
5.2.2. Plug in the power cord (6).
5.2.3. Set the ON/OFF switch (3) to the “-” position and allow tank pressure to build. The motor will stop when tank pressure reaches “cut-out”
pressure.
5.2.4. Turn the air pressure regulator (1) clockwise until desired pressure is reached.
5.2.5. The compressor is ready for use.
WARNING! High temperatures are generated by the electric motor and the pump. To prevent burns or other injuries DO NOT touch the
compressor while it is running. Allow it to cool before handling or servicing.
5.3. HOW TO SHUT DOWN
5.3.1. Set the ON/OFF switch (3) to the “o” position.
5.3.2. Unplug the power cord (6).
5.3.3. Reduce the pressure in the tank through the outlet hose. Pulling the pressure relief and keeping it open will also reduce the pressure in the tank.
5.3.4. Tip the compressor so the drain valve (7) is at the bottom of the tank, then open the drain valve (7) counter-clockwise to allow moisture
to drain from the tank.
CAUTION: escaping air and moisture can propel debris that may cause eye injury. Wear safety glasses when opening the drain valve.
WARNING! To avoid personal injury, always shut o and unplug the unit and relieve all air pressure from the system before
performing any service on the air compressor. Risk of unsafe operation. Unit cycles automatically when power is on. When performing
maintenance, you may be exposed to voltage sources, compressed air or moving parts. Personal injuries can occur. Before performing
any maintenance or repair, disconnect power source from the compressor and bleed o all air pressure.
6. MAINTENANCE
WARNING! Disconnect from all energy supplies before servicing.
WARNING! Display warning signs against reconnection whilst the compressor is being repaired such as:
DO NOT START
MAINTENANCE WORK
IN PROGRESS
WARNING! Air contaminants taken into the compressor will aect optimum performance. Example: Body ller dust or paint overspray

6.3. MONTHLY MAINTENANCE
6.3.1. Inspect air system for leaks by applying soapy water to all joints.
6.3.2. Tighten those joints if leakage is observed.
6.3.3. Check that all nuts and bolts stay tight.
CAUTION: All air line components (including hoses, pipe, connectors, lters, & regulators, etc.) must be rated for a minimum working
pressure of 150 PSI or 150% of the maximum system pressure, whichever is greater. Disconnect any tools from the air supply before
performing maintenance, clearing a jammed fastener, leaving the work area, moving the tool to another location, or handing it to
another person.
When cleaning air lter, or any parts in direct contact with the air production, do not use any ammable or toxic cleaner or solvent
During the break-in period, nuts and bolts have a tendency to loosen up.
After two weeks, tighten all nuts and bolts including head bolts.
Keep the vents and cooling vanes clear of dust and debris. This will help prevent possible electrical shorts and ensure proper cooling
Inspect the cord regularly and have it replaced by an authorized repair facility if it is damaged.
Check the tanks regularly for dents, cracks and other damage. Do not use if any part of the pressurized system is damaged.
An authorized repair centre should do any repairs, modication, or maintenance that involve disassembling the compressor.
