5. HEALTH & 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.
Beware of electric shock. Avoid contact with earthed surfaces; because they can conduct
electricity if there is an electrical fault with the power tool. Always protect the power cable
and route it away from danger.
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.
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 nonslip sole.
5. HEALTH & SAFETY INFORMATION
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 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.
5. HEALTH & SAFETY INFORMATION
Have this tool repaired by a qualified person. This tool is designed to confirm 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.
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. HEALTH & SAFETY INFORMATION
5.3 ADDITIONAL SAFETY INSTRUCTIONS FOR PRESSURE VESSELS
* This pressure tank is mainly intended for static use. It can only be charged with natural
air within temperature and pressure limits as specified on the manufacturer's plate and
declaration of conformity.
e Ensure that tank safety and control devices are efficient and flawless. When replaced,
the tank should not be under pressure.
e Drain the condensation off the tank every day.
e 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 CONNECTION TO THE POWER SUPPLY
Make sure the power supply information on the machine's rating plate are compatible
with the power supply you intend to connect it to.
This compressor comes supplied with a UK standard 3 pin plug fitted. It is designed for
connection to a domestic power supply rated at 230V AC.
Because it is constructed mostly of metal parts, it is a Class 1 machine; meaning, it must
have an earth connection in the power supply. This is to prevent electrocution in the event
of a failure.
Apart from replacing the fuse in the plug, no other electrical work is recommended on this
compressor.

8.6 FINAL CHECKS PRIOR TO USE
LE
Ш 232
hi;
vs
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 (3) is positioned "OFF".
12
9. OPERATING THE COMPRESSOR
9.1 BASIC COMPRESSOR OPERATION
— FIGS. 7-9
— Ensure that the location for the compressor is clean,
dry and well ventilated.
— Ensure the crank case has been filled with oil and is
at the correct level. (for more information see page
12, section 8.5 — filling with oil).
— Check the rating label on the compressor.
— Connect the compressor power cable to a suitable
electrical output point.
NOTE: Use of an extension cord is NOT recommended.
— The compressor is switched on by lifting the on/off
button (3) on top of the pressure unit (Fig. 7).
— The compressor is switched off by pressing the same
on/off button down.
NOTE: This compressor is fitted with 2 pressure gauges
and 2 outlets. Pressure gauge (1.1) displays the tank
pressure and pressure gauge (1) displays the outlet
pressure on the left connector only and is controlled
by the regulator (15). The right connector is at tank
pressure.
— Connect the air line to the compressor by pulling
back the collar on the air outlet quick coupling
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 (3) upwards.
— To obtain the correct output reading on the
regulated output gauge (1), the air must be flowing
through the outlet. The regulating valve should be
adjusted and the gauge read with the outlet valve
open and the air being discharged from the
regulated outlet.
— To increase the pressure, rotate the pressure
regulator clockwise. To decrease the pressure,
rotate the pressure regulator anti-clockwise.
NOTE: If you do not allow the air to discharge while you are setting the regulator, the pressure
as indicated on the regulated outlet gauge will be incorrect. This gauge ONLY indicates the
correct pressure while air is being discharged from the outlet.
The operation is automatically controlled by the pressure switch unit (2) which stops the
motor when the max. pressure allowed is achieved, and starts it again when the pressure
goes below the minimum threshold (about 2 bar less than the max. pressure).
13
9. OPERATING THE COMPRESSOR
— On completion of the task, i.e. when you have finished using the compressor, or when you
are leaving the compressor unattended, turn off the compressor in the following way:
e Press down the on/off button (3).
e Wait for the pressurised air to bleed from the tank from the release valve.
e Switch off the electrical power supply and remove the plug from the outlet point.
WARNING: Never unplug the compressor or switch off the main switch to stop the
compressor. Always position the pressure switch to the off position.
9.2 SAFETY VALVE -FIG. 10
WARNING: DO NOT REMOVE OR ATTEMPT TO ADJUST
THE SAFETY VALVE!
This valve should be checked under pressure
occasionally by pulling the ring by hand. If air
leaks after the ring has been released, or valve is
stuck, it MUST be replaced.
9.3 ADJUSTING THE PRESSURE EL
SWITCH — FIG. 11 LL A
NOTE: This is the only operation where it is acceptable ri % ЗН
to switch the compressor off without using the A CA
1
pressure switch.
To decrease the pressure switch, run the compressor
up to the desired capacity for the pressure switch to
be set. At this point, turn the mains power off and do
not operate the red button on the pressure switch as
this will release the pressure. Disconnect the machine
from the power source before loosening screw to
remove the black cover. With this removed, the
adjustment bolt will be visible. Adjust this anti-clockwise gently until the switch is heard
to release the pressure. Release the cover and tighten the screw. The switch will now be set
to the new pressure. To increase the pressure switch, remove the switch cover (having
disconnected the machine from the power supply) and turn the adjustment bolt clockwise 3
turns and replace the switch cover.
Run the compressor up to the desired capacity for the pressure switch to be set (do not let
the compressor run past it's maximum pressure). At this point turn the mains power off and
disconnect from the supply. Remove the black cover and adjust bolt anti-clockwise gently
until the switch is heard to release the pressure. Replace the cover and tighten the screw. The
switch will now be set to the new pressure.

9. OPERATING THE COMPRESSOR
9.4 OVERLOAD CUT-OUT
The compressor is equipped with an overload cut-out which operates as a safety device to
protect the motor. The device will activate in case of motor overload or overheating due to
operation troubles. In this case, the safety device will automatically activate, disconnecting
the compressor and avoiding possible motor damages. To restart the compressor, proceed as
follows.
e Allow three minutes.
o Position the pressure switch to “0” OFF.
° Manually reset the thermal cut-out.
o Position the pressure switch to “1” ON.
If you restart the compressor and the overload cut-out releases again, turn the main switch
to the OFF position, unplug the equipment and contact the Authorised Service Centre.
NOTE: After reconnection is complete, ensure that the tap is opened again. It is essential to
connect an air line filter separator and lubricator to ensure a good, clean air supply is
provided for the tool.
(NOTE: If the intended tool for use is a spray gun, use only a filter separator as lubrication
will cause contamination of the material being sprayed).
Draper Stock No.43402 - Air filter, Regulator & Lubricator.
Draper Stock No.43394 - Air filter & Regulator.
To ensure an optimum air supply, please refer and carry out the following procedures as
recommended.
9.5 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 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.

11. MAINTENANCE
Some of the operations listed in this section will require the compressor to be returned to an
authorised service agent.
Before carrying out any service or routine operation to your compressor, ensure the power
has been cut off and all pressure has been released from the tank, so as to prevent any
sudden unexpected restart. After any maintenance operation, make sure all components
have been fitted correctly.
In order to keep your compressor in a good working condition, we recommend you to
perform periodical servicing operations. Before performing any maintenance operation,
switch off the compressor and ensure all air in the tank is released.
11.1 OPERATIONS TO BE CARRIED OUT
AFTER THE FIRST 50 WORKING HOURS
Check that all screws and bolts are properly tight,
paying special care to the head and crank case.
Replace the lubricant with one of the recommended
oils listed in the table (see page 18). Never mix
different oils together. Do not use non-detergent oils
or low quality oils as they have very poor lubricating
properties. Do not dispose of the oil in the
environment. Always contact your local authority for
disposal.
11.2 WEEKLY OPERATIONS - FIGS. 12 - 13
Check the oil level and if necessary top up (Fig.13).
Do not exceed the mark corresponding to the max.
level. Make sure the oil does not drop below the
minimum so as to avoid any damage or seizure. Drain
condensation, while the tank is pressurised, by
opening the valve located under the tank
(Fig.14). Open the valve by turning it anti-clockwise
with a container under the valve. Keep the
compressor in a position to allow all condensation to
flow out completely. The tank must have pressure
inside to force out any water present.
11.3 MONTHLY OPERATIONS
(OR MORE FREQUENTLY IF THE
COMPRESSOR OPERATES IN VERY DUSTY
CONDITIONS) — FIG.14
Remove the cover on the air filter module to
access and replace the interior element (12.2). Do not
operate the compressor without the air filter fitted, as
foreign bodies or dust could seriously damage the
inside components.

11. MAINTENANCE
11.4 OPERATIONS TO BE CARRIED OUT
EVERY 6 MONTHS —- FIGS 15-17
Pull out the oil filler cap and loosen the screw
to change the oil. Collect the oil into a suitable
container.
You should perform this operation when the
compressor is hot so as to follow the oil to drain
rapidly and completely. Tighten the screw in its
housing and pour in the new oil up to the max. level
and no higher.
It is advisable to clean all the finned parts of your
compressor, so as to keep the cooling system efficient
and to ensure a long work life to your machine.
Check belt tension. Hang a weight of about 3kg at
the midpoint of the belt. The belt should flex about
10mm (Fig.17).
If necessary, tension up the belt taking care not to
disturb the pulley-to-flywheel alignment. (Fig.18).
11.5 OPERATIONS TO BE CARRIED OUT
EVERY 2 YEARS:
Check the non-return valve and if necessary replace
the seal. Check intake and delivery valves in valve
plates.
11.6 RECOMMENDED OILS:
Recommended oils with ISO grade 100 for
compressors, in accordance with DIN 51506 Standard
(suitable for room temperature ranging from +6°C
and +25°C).
