1. SAFETY INSTRUCTIONS
1.1. ELECTRICAL SAFETY.
q WARNING! It is the user’s responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads, plugs
and all electrical connections for wear or damage. You must ensure the risk of electric shock is minimised by the installation of appropriate
safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend
that an RCD (Residual Current Device) is used with all electrical products. It is particularly important to use an RCD with portable products
that are plugged into an electrical supply not protected by an RCCB. If in doubt consult a professional electrician. You may obtain a
Residual Current Device by contacting your Sealey dealer. You must also read and understand the following instructions concerning
electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
electrician, at least once a year, using a Portable Appliance Tester (PAT).
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances,
and the safety of appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power supply. See 1.1.1. & 1.1.2.
above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply leads and plugs for wear or damage and connections to ensure
that none are loose.
1.1.6. 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 - see fuse rating at right.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty
item repaired or replaced by a qualified electrician. When an ASTA/BS approved UK
3 pin plug is damaged, cut the cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
a) Connect the grEEn/YElloW earth wire to the earth terminal ‘E’.
b) Connect the broWn live wire to the live terminal ‘l’.
c) Connect the bluE neutral wire to the neutral terminal ‘n’.
After wiring, check there are no bare wires, that all wires have been correctly connected, that the cable outer insulation
extends past the cable restraint and that the cable restraint is tight.
Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always
marked with this symbol . To re-wire, connect the brown & blue wires as indicated above. Do noT connect the brown or blue wires
to the earth terminal.
IMPORTANT! The use of extension leads to connect this compressor to the mains is not recommended as the resulting voltage drop
reduces motor, and therefore pump performance.
1.2. GENERAL SAFETY INSTRUCTIONS
3 Familiarise yourself with the application and limitations of the compressor.
3 Ensure the compressor is in good order and condition before use. If in any doubt do not use the unit and contact an electrician/service agent.
WARNING! Compressor must only be serviced by an authorised agent. Do noT tamper with, or attempt to adjust, pressure
switch or safety valve.
3 Before moving, or maintaining the compressor ensure it is unplugged from the mains supply and that the air tank pressure has been vented.
3 Maintain the compressor in good condition and replace any damaged or worn parts. Use genuine parts only. Unauthorised parts may be
dangerous and will invalidate your warranty.

3 Read the instructions relating to any accessory to be used with this compressor. Ensure the safe working pressure of any air appliance
used exceeds compressors output pressure. If using spray a gun, check that the area selected for spraying is provided with a air change
system/ventilation.
3 Ensure the air supply valve is turned off before disconnecting the air supply hose.
3 To move the compressor use the handle only. Lift the compressor so that the front leg gives enough clearance for manoeuvring but
maintain unit’s centre of gravity in front of the wheels. DO NOT attempt to lift or move the compressor by any other means.
3 Use the compressor in a well ventilated area and ensure it is placed on a firm surface.
3 Keep tools and other items away from the compressor when it is in use, and keep area clean and clear of unnecessary items.
3 Ensure the air hose is not tangled, twisted or pinched.
3 Keep children and unauthorised persons away from the working area.
7 DO NOT dis-assemble compressor for any reason. The unit must be checked by qualified personnel only.
7 DO NOT use the compressor outdoors, or in damp, or wet, locations.
7 DO NOT operate within the vicinity of flammable liquids, gases or solids.
7 DO NOT touch compressor cylinder, cylinder head or pipe from head to tank as these may be hot.
7 DO NOT attempt to move the compressor by pulling the air hose. Only move the compressor by
the handle.
7 DO NOT use this product to perform a task for which it has not been designed.
7 DO NOT deface the certification plate attached to the end of the compressor tank.
7 DO NOT cover the compressor or restrict air flow around the unit whilst operating.
q DANGER! DO NOT direct the output jet of air towards people or animals.
7 DO NOT operate the compressor without an air filter.
7 DO NOT allow anyone to operate the compressor unless they have received full instructions.
WARNING! The air tank is a pressure vessel and the following safety measures apply:
7 DO NOT tamper with the safety valve, DO NOT modify or alter the tank in any way and DO NOT strap anything to the tank.
7 DO NOT subject the tank to impact, vibration or to heat and DO NOT allow contact with abrasives or corrosives.
3 Drain condensation from tank daily and inspect inside walls for corrosion every three months and have a detailed tank inspection carried out
annually. The tank shell must not fall below the certified thickness at any point.
WARNING! If an electrical fuse blows, ensure it is replaced with an identical fuse type and rating.
3 When not in use, store the compressor carefully in a safe, dry, childproof location.

3. PREPARATION
3.1. Remove compressor from packaging and inspect for any shortages or damage. If anything is
found to be missing or damaged contact your supplier.
3.2. Save the packing material for future transportation of the compressor. We recommend that
you store the packing in a safe location, at least for the period of the guarantee. Then, if
necessary, it will be easier to send the compressor to the service centre.
3.3. Attach wheels to the compressor as shown in fig.2.
3.4. Confirm that the mains voltage corresponds with the voltage shown on the compressor data
plate.
3.5. The compressor should be operated on a flat surface, or one that does not exceed 10° either
transversely or longitudinally (fig.1) and should be in a position that allows good air circulation
around the unit.
3.6. Remove the plastic transit plug from the oil filler hole and replace it with the dipstick/breather
as shown in figs.4 or 9 (depending on model). It is a push fit, ensure that it is pushed fully home.
3.7. Before using the compressor check the oil level using the dipstick. If the oil is not up to
the mark as shown in fig.3 it should be topped up with Sealey CPO Compressor oil.
fig.2
4. OPERATION
WARNING! Ensure that you have read, understood and apply
Section 1 safety instructions.
IMPORTANT! The use of extension leads to connect this compressor to
the mains is not recommended as the resulting voltage drop reduces
motor, and therefore pump performance.
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. 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.
