4. ASSEMBLY
Unpack the product and check contents. Should there be any damaged or missing parts contact you supplier immediately.
Refer to attached parts list.
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.
4.1. WHEEL ATTACHMENT
4.1.1. Assemble the wheels and swivel castor using the nuts, bolts and washers supplied (fig 2).
4.2. ATTACH THE FILTERS
4.2.1. Screw the filter unit into the port openings in each head as shown in (fig 5).
4.2.2. Place a filter cover over each threaded rod protruding from the back half of the filter and secure each with a wing nut (fig.4).
5. OPERATION
WARNING! Ensure that you have read, and fully understood and apply Section 1 Safety Instructions.
5.1. 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 and could damage your compressor.
5.2. Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
5.3. The compressor should be operated on a horizontal flat surface, or one that does not exceed 5° either transversely (tyres fully inflated
to 1.5bar) or longitudinally with chocks (fig 3), and should be in a position that allows good air circulation around the unit, 1000mm
nominal gap.
5.4. Before using the compressor check the oil level by referring to the oil sight glass (fig 5). On a horizontal surface, if the oil level is not
up to the red centre mark it should be further topped up with recommended oil, see section 6.7.
5.5. To top up undo filler cap (fig 5), top up oil level to required level, then replace filler cap.
5.6. Take care when selecting tools for use with the compressor. Air tool manufacturers normally express the volume of air 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.
5.7. STARTING THE COMPRESSOR.
5.7.1. Your compressor is tted with a push/pull type ON/OFF button to turn the compressor “ON” pull the ON/OFF button upwards.
To turn the compressor “OFF” push the ON/OFF button downwards (g 5).
5.7.2. Check that the ON/OFF button is in the “OFF” position and the regulator dial (fig 6) is closed (Zero ‘0’ bar).
5.7.3. Plug mains lead into mains supply and start the compressor pulling the ON/OFF button (fig 5) upwards.

5.7.4. Leave the compressor running with no air line or tools connected, and regulated pressure gauge (fig 6) set to maximum pressure
(fully clockwise). Make sure that the pressure in the tank rises and that the compressor stops automatically when the maximum is
reached. This value is written on the specification plate and shown on the direct pressure gauge (fig 6). This may take in excess of 5
minutes. The compressor will now operate automatically.
The pressure switch (fig 7) stops the motor when the maximum tank pressure is reached and restarts it when pressure falls below the
minimum threshold approximately 2bar (29psi) less than the maximum pressure.
5.7.5. Stop the compressor by pushing the ON/OFF button (g 5) downwards. The compressed air inside the compressor head will flow out
via the air line tube situated beneath the switch housing. Restart is made easier and prevents the motor from being damaged.
DO NOT, other than in an emergency, stop the compressor by switching off the mains power, or by pulling the plug out, as the
pressure relief will not then occur and motor damage may result upon restart.
When the compressor runs correctly and is stopped correctly there will be:
A: A whistle of compressed air when the motor stops,
B: A protracted whistle (about 20-25 seconds) when the compressor starts with no pressure in the tank.
5.7.6. The output pressure is regulated by the pressure regulator (fig 6). Turn the pressure regulator dial clockwise to increase pressure and
counter-clockwise to reduce it.
To determine the correct working pressure for any piece of equipment check the corresponding manual.
When the compressor is not being used set the regulated pressure to zero so as to avoid damaging the pressure reducer.
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: The direct pressure gauge (fig 5) indicates the pressure inside the main tank. The regulated pressure gauge (fig 6) indicates the
pressure supplied to the air equipment.
Should the pressure in the main tank exceed the pre-set maximum, the safety valve (fig 5) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the pressure switch (fig 7) or safety valve (fig 5).
5.7.7. Should the trip activate, leave for 1 minute before pressing the button to reset.
For possible causes of trip activation see section 6 Troubleshooting.
6. MAINTENANCE
In order to keep the compressor in good working condition, periodic maintenance is essential.
WARNING! Before performing any maintenance operation, switch o󰀨 the compressor, disconnect from electricity supply and
release all air from the tank.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
6.1. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 5 WORKING HOURS:
A: Check that all bolts/nuts are tight, particularly those retaining the crank case and cylinder head.
6.2. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 50 WORKING HOURS:
B: Replace the lubricating oil.
6.3. OPERATIONS TO BE CARRIED OUT DAILY:
A: Drain condensation by opening the valve located under the tank (g 8). Place a container under the valve and slowly open the
valve by turning counter clockwise.
6.4. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS
NOTE: Or more frequently, if the compressor operates in a very dusty atmosphere.
A: Check oil level and, if necessary, top up.
B: Remove the lter elements (g 4) and clean with compressed air (wear eye protection). DO NOT operate the compressor
without the lters as foreign bodies or dust could seriously damage the pump.
C: Check for oil leaks.
6.5. OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:
A: Replace the lubricating oil. For oil specications see 6.7.
Remove the ller cap (g 5) then unscrew the drain plug (g 5) and drain the oil into a suitable waste oil container.
Drain when the compressor is hot so that oil drains rapidly and completely. Incline compressor to ensure complete drainage.
Replace drain plug and rell through the oil ller aperture. DO NOT overll. Replace ller cap.
B: Check the automatic cut-out at maximum pressure and the automatic cut-in at 2bar below.
WARNING! Never mix di󰀨erent oils and DO NOT use non-detergent/low quality oils as the compressor may be damaged.
WARNING! Dispose of waste oil only in accordance with local authority requirements.
6.6. OPERATIONS TO BE CARRIED OUT EVERY 500 HOURS:
A: Replace air lter (g 4 & 5).
B: Check all tube ttings and electrical connections.
6.7. Recommended oil for compressors, suitable for room temperatures ranging from +5°C to +25°C.
SEALEY CPO or equivalent SAE 40 compressor oil. Room temperature below +5°C: SAE 20 compressor oil.
IMPORTANT WARNING - Air contaminants taken into the compressor will a󰀨ect optimum performance. Example: Body ller dust
or paint overspray will clog the pump intake lter and may cause internal damage to pump/motor components.
WARNING! Any parts damaged by any type of contamination will not be covered by warranty.
6.8. Inspection of pressure tank both inside and out.
