1. SAFETY
1.1. ELECTRICAL SAFETY
WARNING! It is the user’s responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and
all electrical connections for wear and damage. Sealey recommend that an RCD (Residual Current Device) is used with all electrical
products. You may obtain an RCD by contacting your local Sealey stockist.
If the product is used in the course of business duties, it must be maintained in a safe condition and routinely PAT (Portable
Appliance Test) tested.
Electrical safety information, it is important that the following information is read and understood.
Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
Important: Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is fitted with the
correct fuse - see fuse rating in these instructions.
DO NOT pull or carry the appliance by the power cable.
DO NOT pull the plug from the socket by the cable.
DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or is
replaced immediately by a qualified electrician.
This product is fitted with a BS1363/A 13 Amp 3 pin plug.
If the cable or plug is damaged during use, switch offthe electricity supply and remove from use.
Ensure that repairs are carried out by a qualified electrician.
Replace a damaged plug with a BS1363/A 13 Amp 3 pin plug. If in doubt contact a qualified electrician.
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’.
Ensure that the cable outer sheath extends inside the cable restraint and that the restraint is tight.
Sealey recommend that repairs are carried out by a qualified electrician.
If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is
preferred since any appliance plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to
be absolutely sure that the capacity of the reel is suitable for this product and for others which may be used in the other output sockets,
we recommend the use of 2.5mm² section cable.
1.2. GENERAL SAFETY

WARNING! The air tank is a pressure vessel and the following safety measures apply:
DO NOT tamper with the safety valve.
DO NOT modify, weld or alter the tank in any way and DO NOT strap anything to the tank.
DO NOT subject the tank to impact, vibration or to heat and DO NOT allow contact with abrasives or corrosives.
DO 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.
When not in use for a long period, store the compressor carefully in a safe, dry, childproof location.
When the compressor is not in use, it should be switched off, disconnected from the mains supply and the air drained from the tank.
IMPORTANT WARNING - Air contaminants taken into the compressor will affect optimum performance. Example: Body filler dust or
paint overspray will clog the pump intake filter and may cause internal damage to pump/motor components. Please note that any parts
damaged by any type of contamination will not be covered by warranty.

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.
4.1. 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.
4.2. STARTING THE COMPRESSOR.
4.2.1. The compressor is fitted with a push ON/OFF switch (fig.2).
4.2.2. To turn the compressor ‘ON’ push the switch. To turn the compressor ‘OFF’ push the
switch again.
4.2.3. Check that the ON/OFF switch is in the “OFF” position and the regulator tap (fig.2) is
closed (Zero ‘0’ bar, Anti-clockwise).
4.2.4.
Plug mains lead into mains supply and start the compressor by pushing the ON/OFF switch.
4.2.5. Leave the compressor running with the regulator tap (fig.2) set to maximum pressure.
Make sure that the pressure in the tank rises and that the compressor stops automatically
when the maximum pressure value allowed - written on the specification plate is achieved.
The compressor will now operate automatically.
4.2.6. The pressure switch stops the motor when the maximum tank pressure is reached, and will
restart it when pressure falls below the minimum threshold - approx. 2 bar (29psi) less than
the maximum pressure.
4.2.7. Stop the compressor by pushing the ON/OFF switch (fig.2). The compressed air inside the compressor head will flow out, making the
restart easier and preventing the motor from being damaged.
DO NOT, other than in an emergency, stop the compressor by switching off the mains socket, or by pulling the plug out of the socket,
as the pressure relief will not then occur and motor damage may result upon restart.

4.2.8. The output pressure is regulated by the pressure regulator tap (fig.2). Turn the tap clockwise to increase pressure and anti-clockwise to
reduce it, view the result on the output regulator gauge (fig.2).
NOTE: a) If the motor does not cut in and out, but runs continuously when using an air appliance, the capacity of the compressor may
be too small for the equipment or tool.
b) Should the pressure in the main tank exceed the pre-set switch maximum, the safety valve (located under the motor cowling
adjacent to the regulator gauge) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the pre-set switch or safety valve.
5. MAINTENANCE
In order to keep the compressor in good working condition, periodic maintenance is essential.
WARNING! Before performing any maintenance operation, switch offthe compressor, disconnect from electrical supply and release all
air from the tank.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
5.1. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 5 WORKING HOURS:
a) Check that all nuts/bolts are tight, particularly those retaining the crankcase and cylinder heads.
5.2. OPERATIONS TO BE CARRIED OUT DAILY:
a) Drain condensation by opening the valve located under the tank (fig.4). Place a container under the valve to collect any
condensation.
Tip the compressor slightly towards the drain valve to ensure all condensation drains. Close valve after draining condensation and
dispose of it safely.
b) Regularly clean dirt and dust away from the safety devices with a clean cloth or blowing with low pressure compressed air.
Generally keep the compressor clean.
5.3. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS:
(Or more frequently, if the compressor operates in a very dusty atmosphere)
CLEAN AIR FILTER
a) Ensure the power is offand the tank has been vented. Remove the cowling from the motor by removing the four retaining screws.
NOTE! When removing the cowling, care should be taken not to inadvertently disconnect the wires from the switch.
b) Remove the filter element by pulling the filter cover from the housing (fig.3).
Clean and replace the filter element. Snap the cover back into place.
5.4. OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:
a) Check the automatic cut-out at maximum pressure and the automatic cut-in at 2 bar below maximum pressure.
b) Replace air filter.
5.5. OPERATIONS TO BE CARRIED OUT EVERY 400 HOURS:
a) Check all fittings and electrical connections.
b) Inspect pressure tank inside and out for damage or corrosion.
