1. The air compressor should be placed in a clean, dry and ventilated area
2. In order to extend the compressor lifespan, reduce the heat of moving parts by making sure the
air compressor cover is at least 0.3 - 0.5 metres away from the wall
3. Keep the voltage within ±5% of rating
4. Keep the oil level within the indicator
5. Recommended compressor oil AC2100 or AC2032
6. The normal working temperature should be -5°C - +35°C
7. The normal working temperature of the air compressor is 180°C and lubricating oil
in the crankcase is 70°C
8. Open the outlet valve and let the air compressor run for 10 minutes without load before operation
Preparation for Usage
Safety Guidelines
DANGER
1. TO REDUCE THE RISK OF FIRE OR EXPLOSION, NEVER SPRAY FLAMMABLE
LIQUIDS IN A CONFINED AREA. It is normal for the motor and pressure switch to produce
sparks while operating. If sparks come into contact with vapours from gasoline or other
solvents, it may ignite fire or an explosion. The air compressor must be stored and operated
in a well-ventilated area. Do not smoke while using the air compressor, and keep away from
flammable material.
2.
When Trichloroethane and Methylene Chloride come into contact with aluminium in painting
equipment, it can produce a chemical reaction which may cause an explosion. If you are using
these solvents, please use only stainless steel spray equipment.
3. Never directly inhale the compressed air produced by a compressor.

WARNING
1. Do not weld onto the air tank of this compressor. Welding on the air compressor tank will cause a
safety hazard and will void the product warranty
2. Never use an electric air compressor outdoors or on a wet surface; it may cause an electric shock
3. Please power off the air compressor when not in use
4. Check the manufacturer’s maximum pressure rating for air tools and accessories.
The compressor outlet pressure must be regulated so as not to exceed the maximum pressure
rating for the tools
5. High temperatures and moving parts are present under the outer cover. To prevent burns or
other injuries, DO NOT operate with the outer cover removed. Allow the compressor parts to cool
before handling or servicing
6. Ensure you read all labels when you are spraying paints or toxic materials; follow the safety
instructions provided, and use a respirator mask
7. Always wear safety goggles or glasses when using an air compressor. Never point any nozzle or
sprayer towards a person or any part of the body
8. Do not adjust the pressure switch or regulating valve for any reason; they have been pre-set at the
factory for the maximum pressure for this unit
CAUTION:
1. Drain the moisture from the tank on a daily basis. A clean, dry tank will help prevent corrosion
2. Pull off the pressure relief valve ring daily to ensure that the valve is functioning properly, and to
clear any obstructions
3. To provide adequate ventilation for cooling, the compressor must be kept a minimum of 0.3-0.5
metres from the nearest wall, in a well-ventilated area
4. Fasten the compressor down securely, and release the pressure from the tank before
transportation
5. Protect the air hose and electrical wire from damage and punctures. Inspect them weekly for
weak or worn spots, and replace them if necessary

This range of Synairgy oil lubricated compressors are built with performance and reliability in mind,
with a robust strong design for trade and DIY applications. The compressors have the advantage
of a compact construction and lightweight design. Easy operation, excellent safety characteristics
and low noise levels make it perfect for all typical applications, including; paint spraying, inflating,
blowing, nailing, air tools and other applications where compressed air is required.
1. Pull the cover off and connect the breather pipe and air filter before running the compressor
2. Never unscrew any connecting parts when the tank is pressurised
3. Disconnect the plug before disassembling any electrical part
4. Never adjust the safety relief valve
5. Never use the compressor when the voltage is too low or too high
6. Never use electrical wire more than 5m long
7. Never disconnect the plug to stop the compressor; turn the switch to off instead
8. If the outlet valve doesn’t work, search for the cause immediately so as not to damage the motor
9. Lubricating oil must be clean; oil level should be kept within the indicator
10. Before opening the outlet valve ensure the compressor is switched off and the plug is
disconnected from the power supply
11. The maximum decibel level or the compressor is 87dB

1. Open the drain cock under the tank and then close it
2. The compressor is controlled by the pressure switch. It can be stopped automatically as
pressure increases to the maximum and restarted as pressure decrease to the minimum.
The rated pressure has been set during production; do not adjust needlessly. As soon as the
motor is switched off the compressed air in the discharge pipe should be released through
the outlet valve under the switch, this is required for restarting, or the motor will be damaged
The rated pressure can be adjusted by turning
the adjusting bolt of the switch
3. The outlet pressure of compressed air can be
adjusted, by the regulating valve (Fig.3). Pull
up the knob of the regulation valve and turn it
clockwise to increase the pressure
4. When the compressor needs to be stopped,
set the switch to the off position
1. Clean the crankcase and replace the lubricating oil after the first 10 working hours
2. Clean the oil level after every 20 working hours, and replenish it if necessary
3. Open the drain cock under the tank to exhaust condensation after every 60 working hours
4. Clean the crankcase every 120 working hours and renew the oil, clean the air filter, check the
safety valve and pressure gauge
