Sealey SA9925/1.5 User manual

1.1. ELECTRICAL SAFETY. p 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 is loose.
1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply
to be used, and check that plugs are fitted with the correct capacity fuse. A 13Amp plug may require
a fuse smaller than 13Amps for certain products (subject to 1.1.10. below) - see fuse rating at right.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead. Products such as
welders must not be pulled or carried by their output cables.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by
a qualified electrician. Where a U.K. 3 pin plug with ASTA/BS approval is fitted, in case of damage, cut off
and fit a new plug according to the following instructions (discard old plug safely).
(UK only - see diagram at right). Ensure the unit is correctly earthed via a three-pin plug.
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.
1.1.10. NOTE: If this product requires more than a 13Amp electrical supply, then NO plug is fitted. You must therefore contact a qualified electrician to ensure
a 30 amp fused supply is available. We recommend you discuss the installation of a industrial round pin plug & socket with your electrician.
1.1.11. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD
fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cores in the cable
is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of the cable reel is
suitable for this product and for others that may be used in the other output sockets, we recommend the use of 2.5mm2section.

1.2. GENERAL SAFETY INSTRUCTIONS
Familiarise yourself with the application and limitations of the compressor.
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.
pWARNING! Compressor must only be serviced by an authorised agent. DO NOT tamper with, or attempt to adjust, pressure switch or safety valve.
Before moving, or maintaining the compressor ensure it is unplugged from the mains supply and that the air tank pressure has been vented.
Only use recommended attachments and parts. To use non-recommended items may be dangerous and will invalidate your warranty.
Read the instructions regarding any accessory used with the compressor. Ensure the safe working pressure of any air appliance used exceeds
units output pressure. If using spray gun, check that the area selected for spraying is provided with air change system/ventilation.
Ensure the air supply valve is turned off before disconnecting the air supply hose.
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 means other than by handle.
Use the compressor in a well ventilated area and ensure it is placed on a firm surface.
Keep tools and other items away from the compressor when it is in use, and keep area clean and clear of unnecessary items.
Ensure the air hose is not tangled, twisted or pinched.
Keep children and unauthorised persons away from the working area.
DO NOT dis-assemble compressor for any reason. The unit must be checked by qualified personnel only.
DO NOT use the compressor outdoors, or in damp, or wet, locations and DO NOT operate within the vicinity of flammable liquids, gases or solids.
DO NOT touch compressor cylinder, cylinder head or pipe from head to tank as these may be hot and will remain so for some time after shutdown.
DO NOT attempt to move the compressor by pulling the air tool hose. Only move the compressor by its handle.
DO NOT use this product to perform a task for which it has not been designed.
DO NOT deface the certification plate attached to the end of the compressor tank.

2. INTRODUCTION & SPECIFICATIONS
The SA9925/1.5 & /2 and the SA9950/2 Direct Drive Compressors have single cylinder pumps powered by 230V 1ph motors and are capable
of supplying air at up to 8 bar from a 25 litre tank in the case of SA9925 models, and a 50 litre tank in the case of the SA9950/2. In addition to
pneumatic tools, the compressors may be connected to accessories suitable for blowing, washing and spraying. All compressors have two
rear wheels and a handle for ease of movement.

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. Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
3.4. The compressor should be operated on a flat surface, or one that does not exceed 15Oeither transversely or longitudinally (fig.1), and
should be in a position that allows good air circulation around the unit.
3.5. Replace transit plug in oil filler aperture with filler plug ( para.5.4.A) provided.
3.6. Confirm oil level is at maximum mark on the sight glass (fig.2).
3.7. Screw air filter (fig.3.A) into inlet port.

4. OPERATION
5. MAINTENANCE
In order to keep the compressor in good working condition, periodical maintenance is essential.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
pWARNING! Before performing any maintenance operation, switch off the compressor, disconnect
from electricity supply and release all air from the tank.
5.1. Operations to be carried out after the first 50 working hours:
a) Check that all bolts/nuts are tight, particularly those retaining the crank case and cylinder head.
b) Replace the lubricating oil - see para 5.5.
5.2. Operations to be carried out daily:
a) Drain condensation by opening the valve located under the tank. Place a container under the valve and
open the valve by turning anticlockwise.
5.3. Operations to be carried out every 100 hours (or more frequently, if the compressor operates in a very dusty atmosphere):
a) Check oil level and, if necessary, top up.
b) Remove the filter element (fig.2) and clean by blowing through, with an air line at low pressure, from
the clean side or wash in soapy water, rinse and dry. Do not operate the compressor without the filter as
foreign bodies or dust could seriously damage the pump.
c) Check for oil leaks
5.4. Operations to be carried out every 200 hours:
a) Replace the lubricating oil. For oil specifications see 5.7.
Remove the oil filler plug A and unscrew sight glass B, draining the oil into a container. Drain when the
compressor is hot so that oil drains rapidly and completely. Incline compressor to ensure complete drainage.
Replace sight glass and refill through the filler aperture. Do not overfill. Replace plug A.
pWARNING! Never mix different oils and do not use non-detergent/low quality oils as the compressor may be damaged.
pWARNING! Dispose of waste oil only in accordance with local authority requirements.
b) Check the automatic cut-out at max. pressure and the automatic cut-in at 2 bar below.
5.5. Operations to be carried out every 500 hours:
a) Replace air filter.
After completing the preparation the compressor is ready to operate.
p IMPORTANT
1. The use of extension leads to connect these compressors to the mains is not recommended since the resulting voltage drop
would reduce motor, and therefore pump, performance.
2. 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 - and so it is important that,
before choosing equipment, you study the Free Air Delivery figures shown in the Specification chart, section 2.
p WARNING! Ensure that you have read, understood and apply section 1 safety instructions.
4.1. Make sure the main switch (fig.4.1) is in position "O, off.
4.2. Plug the mains lead into mains supply and start the compressor by turning the main switch (1) to I, on.
4.3. When starting the compressor for the first time, leave it running with air outlet (7) closed and
reducer (3) set to maximum pressure. Make sure that pressure in the tank rises and that the
compressor stops automatically when the max. pressure value allowed - written on the plate and
shown on the gauge (2) - is achieved.
The compressor will now operate automatically. The pressure switch stops the motor when the maximum
tank pressure is reached and restarts it when pressure falls below the minimum threshold - approx. 2 bar
(29psi) less than the maximum pressure.
4.4. Stop the compressor by turning the main switch off (fig.4). 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, 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.
4.5. The output pressure is regulated by the pressure reducer (fig.4.3). Lift and turn the knob clockwise to increase pressure and
anticlockwise to reduce it - push knob down to lock in required position. 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 gauge (fig.4.2) indicates the pressure inside the main tank, NOT the pressure supplied to the air equipment. Should the pressure
in the main tank exceed the pre-set switch (6) maximum, a safety valve (5) will activate. WARNING! for this reason DO NOT tamper
with or adjust the switch or safety valve.
