5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
When using any type of power tool there are steps that should be taken to make sure that you, as
the user, remain safe.
Common sense and a respect for the tool will help reduce the risk of injury.
Read the instruction manual fully. Do not attempt any operation until you have read and
understood this manual.
Most important you must know how to safely start and stop this machine, especially in an
emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the machine during
use will reduce your concentration. Mess on the floor creates a trip hazard. Any liquid spilt on the
floor could result in you slipping.
Find a suitable location. If the machine is bench mounted, the location should provide good
natural light or artificial lighting as a replacement. Avoid damp and dust locations as it will have a
negative effect on the machine’s performance. If the machine is portable do not expose the tool to
rain. In all cases do not operate power tools near any flammable materials.
Keep bystanders away. Children, onlookers and passers by must be restricted from entering the
work area for their own protection. The barrier must extend a suitable distance from the tool user.
Unplug and house all power tools that are not in use. A power tool should never be left unattended
while connected to the power supply. They must be housed in a suitable location, away locked up
and from children. This includes battery chargers.
Do not overload or misuse the tool. All tools are designed for a purpose and are limited to what
they are capable of doing. Do not attempt to use a power tool (or adapt it in any way) for an
application it is not designed for. Select a tool appropriate for the size of the job. Overloading a tool
will result in tool failure and user injury. This covers the use of accessories.
Dress properly. Loose clothing, long hair and jewellery are all dangerous because they can
become entangled in moving machinery. This can also result in parts of body being pulled into the
machine. Clothing should be close fitted, with any long hair tired back and jewellery and neck ties
removed. Footwear must be fully enclosed and have a non-slip sole.
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf can all be
dangerous if not suitably protected against. If the work involving the power tool creates dust or
fumes wear a dust mask. Vibration to the hand, caused by operating some tools for longer periods
must be protected against. Wear vibration reducing gloves and allow long breaks between uses.
Protect against dust and swarf by wearing approved safety goggles or a face shield. These are
some of the more common hazards and preventions, however, always find out what hazards are
associated with the machine/work process and wear the most suitable protective equipment
available.
Do not breathe contaminated air. If the work creates dust or fumes connect the machine (if
possible) to an extraction system either locally or remotely. Working outdoors can also help if
possible.
Move the machine as instructed. If the machine is hand held, do not carry it by the power supply
cable. If the product is heavy, employ a second or third person to help move it safely or use a
mechanical device. Always refer to the instructions for the correct method.
Do not overreach. Extending your body too far can result in a loss of balance and you falling. This
could be from a height or onto a machine and will result in injury.
Maintain your tools correctly. A well maintained tool will do the job safely. Replace any damaged
or missing parts immediately with original parts from the manufacturer. As applicable, keep blades
sharp, moving parts clean, oiled or greased, handles clean, and emergency devices working.
Wait for the machine to stop. Unless the machine is fitted with a safety brake, some parts may
continue to move due to momentum. Wait for all parts to stop, then unplug it from the power supply
—6—
5. HEALTH AND SAFETY INFORMATION
before making any adjustments, carrying out maintenance operations or just finishing using the
tool.
Remove and check setting tools. Some machinery requires the use of additional tools or keys to
set, load or adjust the power tool. Before starting the power tool always check to make certain they
have been removed and are safely away from the machine.
Prevent unintentional starting. Before plugging any machine in to the power supply, make sure
the switch is in the OFF position. If the machine is portable, do not hold the machine near the
switch and take care when putting the machine down, that nothing can operate the switch.
Carefully select an extension lead. Some machines are not suitable for use with extension
leads. If the tool is designed for use outdoors, use an extension lead also suitable for that
environment. When using an extended lead, select one capable of handling the current (amps)
drawn by the machine in use. Fully extend the lead regardless of the distance between the power
supply and the tool. Excess current (amps) and a coiled extension lead will both cause the cable to
heat up and can result in fire.
Concentrate and stay alert. Distractions are likely to cause an accident. Never operate a power
tool if you are under the influence of drugs (prescription or otherwise), including alcohol or if you
are feeling tired. Being disorientated will result in an accident.
Have this tool repaired by a qualified person. This tool is designed to conform to the relevant
international and local standards and as such should be maintained and repaired by someone
qualified, using only original parts supplied by the manufacturer. This will ensure the tool remains
safe to use.
5.2 ADDITIONAL SAFETY INSTRUCTIONS FOR SAFETY VALVES
Information
The safety valves are designed and constructed for use exclusively with compressed air, free from
impurities. The materials used in construction are suitable for operating the valve at the rated
pressure and temperatures. The Viton or NBR gasket conserves the resistance characteristics,
even in prolonged use. The valve caulking impedes calibration modification; tampering with the
valve and/or changing the constructor’s calibration is forbidden.
Installation
Valve installation must be performed exclusively by technically prepared persons, who are
responsible and in good health. Checking the integrity of the valve before installation is obligatory.
Also, check that the valve pressure is no greater than the operating pressure of the tank or of the
system to protect. Check that the discharge flow rate of the valve is greater than the quantity of the
air to discharge. The safety valve must be positioned directly on the tank in a vertical position, in a
dry, accessible place protected against the weather and far away from liquids or condensation. It
must be positioned so as to have sufficient space all around for correct air discharge, without
causing damage to persons and/or things. The valve rod must therefore be free in its movement
when discharging. The connection between the valve and the part to be protected must be free
from all kinds of choking and be as short as possible so as not to reduce the discharge flow rate of
the valve itself. The connection passage area must be greater than the valve orifice area. During
installation, screw on the valve with a torque spanner using the hexagonal part of the body. Apply
a maximum torque of 30Nm, paying attention not to cause any deformation; using pincers, pliers,
hammers or tools other than a hexagonal spanner is forbidden. Check the inlet hole and the
shutter are not blocked by glue, teflon or similar materials that could bind the shutter or other
functional components. If the valve is replaced, the compressor air contained in the system must
be discharged first. We decline all responsibility for damage caused to persons and/or things due
to failure to observe these instructions.
5. HEALTH AND SAFETY INFORMATION
Maintenance and inspection:
The valve must not be subject to knocks which may cause deformities. It is obligatory for qualified
technicians to make sure that the safety valve functions correctly at least once a year. Valves
equipped with a ring must be tested while pressurised to between 80 — 90% of the calibration
value. Pull the ring and release immediately. During the test the valve must definitely open and
discharge the air and re-close immediately when the ring is released. It is absolutely necessary to
carry out this procedure with the utmost caution because this type of job can be dangerous if
adequate safety measures are not taken; wear goggles, a head set and anything else necessary
to protect against noise, jets of air, etc. which may be discharged from the valve.
5.3 ADDITIONAL SAFETY INSTRUCTIONS FOR PRESSURE VESSELS
— This pressure tank can only be charged with natural air within temperature and pressure limits
as specified on the manufacturer’s plate and declaration of conformity.
— Ensure that tank safety and control devices are efficient and flawless. When replaced, the tank
should not be under pressure.
— Drain the condensation off the tank every 7 days.
— Check for signs of inner corrosion at regular intervals. Tank walls should have a minimum
thickness of 1.0 — 2.0mm.
— Any kind of welding to the tank is forbidden.
— The user shall comply with laws on pressure vessel operation in force in the country in which
the tank is operated.
— The construction is mainly effected for permanent load by internal pressure. Cyclic loads are
not considered, only for a range of 10% PS.
5.4 RESIDUAL RISK
Important: Although the safety instructions and operating manuals for our tools contain extensive
instructions of safe working with power tools, every power tool involves a certain residual risk
which can not be completely excluded by safety mechanisms. Power tools must therefore always
be operated with caution!
5.5 CONNECTION TO THE POWER SUPPLY
Caution: Risk of electric shock. Do not open.
This appliance is supplied with a moulded 3 pin mains plug for your safety. The value of the fuse
fitted is marked on the pin face of the plug. Should the fuse need replacing, ensure the substitute
is of the correct rating, approved to BS1362 and ASTA or BS Kite marked.
ASTA
BSI Y
Make sure the power supply information on the machine's rating plate are compatible with the
power supply you intend to connect it to.
If a replacement plug is to be fitted this must be carried out by a qualified electrician.
The damaged or incomplete plug, when cut from the cable shall be disabled to prevent connection
to a live electrical outlet.
This appliance is Class |? and is designed for connection to a power supply matching that detailed
on the rating label and compatible with the plug fitted.
If an extension lead is required, use an approved and compatible lead rated for this appliance.
Follow all the instruction supplied with the extension lead.
tEarthed: = This product requires an earth connection to protect against electric shock from
accessible conductive parts in the event of a failure of the basic insulation.
5. HEALTH AND SAFETY INFORMATION
Important: If using an extension lead, follow the instructions that came with your lead regarding
maximum load while cable is wound. If in doubt, ensure that the entire cable is unwound. Using a
coiled extension lead will generate heat which could melt the lead and cause a fire.

8. PREPARING THE COMPRESSOR
Note: Remove the plug from the socket before
carrying out adjustment, servicing or maintenance.
8.1 LOCATION AND ASSEMBLY -
FIG. 1
It is extremely important to install the compressor
in a clean, well ventilated area where the
surrounding air temperature will not be more than
40°C. A minimum clearance of 500mm between
the compressor and a wall is required.
Fitting the air filter:
Remove the transit bung from the top of the head
and screw the air filter into the filter FIG.1
connection.
In addition to pneumatic air tools, your compressor
may be connected to several accessories suitable
for blowing, washing and spraying. For technical
specifications and detailed instructions, please
refer to the instructions provided for the individual
accessory.
When the installation procedure is complete, the
compressor is ready for use. Make sure the
pressure switch button (2) is positioned “OFF”.
Switch the pressure switch button to the “ON”
position to start the compressor.
8.2 INITIAL STARTUP — FIGS. 2 — 3
— Insert a euro connector into the air outlet
connector (4) and open the regulator (3) fully.
— Turn the compressor on by pulling the pressure
switch On/Off button (2) up.
— Run the compressor for 30 minutes allowing
the pressure to escape.
— Turn the regulator dial fully counter-clockwise
allowing pressure to build up. Once the
maximum pressure is reached, the pressure
switch will automatically turn the machine off.
— Turn the compressor off, by pressing the FIG.3
pressure switch On/Off button down and open
the regulator valve allowing the air to escape.
— 12 —
9. OPERATION
9.1 BASIC COMPRESSOR
OPERATION — FIG. 4
Connect the air line to the compressor by
pulling back the collar (4.1) on the air outlet
quick coupling (4) and inserting the
corresponding air coupling fitted on the air line.
Release the collar so it slides back in place to
secure the air coupling.
— Turn the air regulator clockwise to its lowest
setting and turn on the compressor by lifting the
pressure switch On/Off button (2) upwards.
— Once the compressor has reached maximum
pressure, open the regulator valve (3) to the
desired pressure on the air outlet regulator
gauge (7).
9.2 MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets
as it comes from an air compressor pump. When
humidity is high or when a compressor is in
continuous use for an extended period of time, this
moisture will collect in the tank. When using a paint
spray gun or sandblast gun, this water will be
carried from the tank through the hose, and out of
the gun as droplets mixed with the spray material.
Important: This condensation will cause water
spots in a paint job, especially when spraying other
FIG.5
than water based paints. If sandblasting, it will cause the sand to case and clog the gun rendering
it ineffective. A filter in the air line, located as near to the gun as possible, will help eliminate this
moisture.
9.3 SAFETY VALVE - FIG.5
Warning! Do not remove or attempt to adjust the safety valve!
The valve has been factory set to operate automatically in the event of an excess air pressure
malfunction.
—13—
9. OPERATION
9.4 THERMAL OVERLOAD PROTECTOR
Caution: This compressor is equipped with an automatic reset thermal overload protector, which
will shut off the motor if it becomes overheated.
If thermal overload protector shuts motor OFF frequently, look for the following causes.
— Low voltage.
— Clogged air filter.
— Lack of proper ventilation.
Caution: If the thermal overload protector is actuated, the motor must be allowed to cool down
before start-up is possible. The motor will automatically restart without warning if left plugged into
electrical outlet and unit is turned on.
9.5 STORAGE
— When not in use, store hose and compressor in a cool dry place.
— Drain tank of moisture.
— Disconnect hose and hang open ends down to allow any moisture to drain.

10.2 BASIC MAINTENANCE AND
CHECKS — FIG. 6
Note: Remove the plug from the socket before
carrying out adjustment, servicing or maintenance.
In order to maintain the compressor to its optimum,
periodical service checks must be carried out
routinely. Allowances should be made to adjust the
time scale for machines in occasional service with
the exception of the safety valve which must be
inspected by a qualified service agent every 12
months regardless of use.
Note: Where necessary, ear defenders and safety
goggles must be worn.
Daily checks:
FIG.6
— Before every use check the airline/regulator/separator.
— After every use adjust the line pressure back to zero.
Monthly checks:
— Remove the foam air filter element for cleaning or renew if necessary.
e Rinse the filter with water and soap. Make certain the element is completely dry prior
to re-fitting.
The cleaning/replacement of the air filter must be carried out more frequently if the compressor is
operating in a dusty environment.
The motor must be correctly ventilated during operation. For this reason avoid blocking the air
inlets. After use disconnect the compressor from the power supply and vacuum the ventilation slots.
If replacement of the supply cord becomes necessary, this will need to be completed by the
manufacturer or an appointed agent in order to avoid potential safety hazards.
Warning! Never attempt to run the compressor without the filter element fitted as dust or foreign
bodies can enter the pump unit resulting in serious damage.
