use and service the machine have to be acquainted with  
this Manual and must be informed about its potential  
hazards. Children and infirm people must not use this  
tool. Children should be supervised at all times if they  
are in the area in which the tool is being used. It is  
also imperative that you observe the accident prevention  
regulations in force in your area. The same applies for  
general rules of occupational health and safety.  
Warning. When using power tools, basic safety  
precautions should always be taken to reduce the risk of  
fire, electric shock and personal injury. Also, please read  
and heed the advice given in the additional important  
safety instructions.  
11. Do not overreach. Keep your footing secure and  
balanced at all times.  
12. Look after your tools. Keep tools sharp and clean for  
better and safer performance. Follow the instructions  
regarding lubrication and accessory changes. Inspect  
tool cords periodically and, if damaged, have them  
repaired by an authorised service facility. Inspect  
extension cords periodically and replace them if  
damaged. Keep tool handles dry, clean and free from  
oil and grease.  
13. Disconnect idle tools. Switch off the power and  
disconnect the plug from the power point before  
servicing, when changing accessories and when the  
tool is not in use.  
1. Keep the work area clean and tidy. Cluttered work  
areas and benches invite accidents and injury.  
2. Consider the environment in which you are working.  
Do not use power tools in damp or wet locations.  
Keep the work area well lit. Do not expose power tools  
to rain. Do not use power tools in the presence of  
flammable liquids or gases.

To reduce the risk of fire or explosion, never spray  
flammable liquids in a confined area. It is normal for  
the compressor motor and pressure switch to produce  
sparks during use. If sparks come into contact with  
petrol vapours or solvents, they may ignite the vapours  
and cause a fire or explosion.  
Always operate the compressor in a well ventilated area.  
Do not smoke while spraying. Do not spray where sparks  
or flames are present. Keep the compressor as far away  
from the spray area as possible.  
The solvents trichloroethane and methylene chloride can  
chemically react with the aluminium used in some paint  
spray guns and form an explosion. If these solvents are  
used, ensure that only stainless steel spray equipment is  
connected. The compressor is not affected by the use of  
these solvents.  
17. Stay alert. Watch what you are doing. Use common  
sense. Do not operate a power tool when you are  
tired.  
18. Check for damaged parts. Before using a tool,  
check that there are no damaged parts. If a part is  
slightly damaged, carefully determine if it will operate  
properly and perform its intended function. Check for  
alignment of moving parts, binding of moving parts,  
breakage of parts, proper mounting and any other  
conditions that may affect the operation of the tool.  
A part that is damaged should be properly repaired  
or replaced by an authorised service facility, unless  
otherwise indicated in this Instruction Manual.  
Defective switches must be replaced by an authorised  
service facility. Do not use a tool if the switch does  
not turn the tool on and off correctly.  
19. Guard against electric shock. Prevent body contact  
with grounded objects such as water pipes, radiators,  
cookers and refrigerator enclosures.  
Never directly inhale the compressed air produced by  
a compressor and do not use it for charging breathing  
tanks.  
20. Use only approved parts. When servicing, use only  
identical replacement parts. Use an authorised service  
facility to fit replacement parts.  
Do not use welding equipment in close proximity to the  
compressor. Do not weld anything to the air tank of the  
compressor: this could dangerously weaken the tank and  
will void the warranty.  
Do not use the compressor outdoors when it is raining  
or on a wet surface; either situation could cause an  
electric shock.  
Always shut off the compressor after use and before  
servicing. Push the on/off knob down, wait for the  
pressurised air to bleed from the tank from the release  
valve and then remove the electrical plug from the  
power supply.  
Check the maximum pressure rating of any tools or  
accessories that you intend using with the compressor.  
The output pressure of the air from the compressor must  
be regulated so that it never exceeds the rated pressure  
of the tool or accessory.  
Additional safety rules for air compressors  
Warning. Before connecting a tool to a power source  
(mains switch power point receptacle, outlet, etc.) be sure  
that the voltage supply is the same as that specified on  
the nameplate of the tool. A power source with a voltage  
greater than that specified for the tool can result in  
serious injury to the user, as well as damage to the tool.  
If in doubt, do not plug in the tool. Using a power source  
with a voltage less than the nameplate rating is harmful  
to the motor.  
Always remove the plug from the mains socket before  
making any adjustments or maintenance, including  
renewing the lubricating oil.

To avoid the risk of burns and injury from moving parts,  
do not operate the compressor with the safety shield  
removed. Allow hot parts to cool before handling or  
servicing.  
Be certain to read all the labels on the containers of  
paint or other materials to be sprayed. Closely follow  
all safety instructions. Use a respirator mask if there  
is a chance that you might otherwise inhale the spray  
material. Carefully check the effectiveness of any  
respirator mask you intend using.  
Always wear safety goggles or glasses when using the  
air compressor. Never point the nozzle of an accessory  
towards any part of your body or towards another  
person.  
Do not attempt to adjust the pressure switch or the  
release valve located under the pressure switch cover.  
Drain the moisture from the tank daily. It will help  
prevent corrosion.  
Pull the ring on the safety valve daily to ensure that  
it operating properly and to clear any possible instruc-  
tions.  
Keep the compressor at least 300mm from the nearest  
wall to ensure adequate ventilation for cooling  
purposes.  
Before transporting the compressor make sure that  
the pressurised air is bled from the tank and that the  
compressor is firmly secured.  
Always press the on/off button down to switch off the  
compressor before switching off the power or removing  
the power plug.  
Do not use the compressor without first checking the oil  
level. It must be close to the red circle as viewed on the  
oil gauge.  
NOTE. The compressor is supplied empty of oil. It must be  
filled with oil before first use.  
After using the compressor, switch off the on/off  
button, disconnect the power supply and open the  
outlet valve to release the pressure.  
Do not attempt to remove any part of the machine  
whilst it is under pressure.  
Ensure that the lubricating oil is clean and that the oil  
level is maintained at the correct level. Replace the oil  
as indicated in the Maintenance section of this Manual.  
Use safety equipment including safety goggles or  
shield, ear protection, breathing or respirator mask and  
protective clothing.  
Wear goggles.  
Wear earmuffs.  
Wear a breathing or respirator mask.  
Never apply the outlet air of this compressor directly on to  
any part of a person’s body. Do not attempt to block the  
air outlet with your finger or any part of your body.  
The tool must be used only for its prescribed purpose. Any  
use other than those mentioned in this Manual will be  
considered a case of misuse. The user and not the manu-  
facturer shall be liable for any damage or injury resulting  
from such cases of misuse.  
Protect the air hose and cordset from damage.  
Inspect for weak or worn spots regularly and replace if  
necessary.  
Do not use an extension cord with this product. Use  
additional air hose instead of an extension cord to  
prevent power loss and possible damage to the motor.  
Use of an extension cord voids the warranty.  
The manufacturer shall not be liable for any changes  
made to the tool nor for any damage resulting from such  
changes.  
After long working periods external metal parts could

Even when the tool is used as prescribed it is not possible  
to eliminate all residual risk factors. The following hazards  
may arise in connection with the tool’s construction and  
design:  
Damage to the lungs if an effective breathing mask is  
not worn.  
Damage to hearing if effective earmuffs are not worn.  
Damage to the eyes if effective safety goggles or shield  
are not worn.  
Warning.  
In the event that an air line is cut or broken, the air  
supply must be turned off at the compressor. A broken air  
line which is not supported is extremely dangerous and  
can whip around very quickly, both with the capability of  
striking people, and blowing foreign particles into the air.  
Do not attempt to catch the air line but immediately keep  
bystanders well clear and turn off the air supply to the  
hose, turn off the compressor at the On / Off button, and  
then remove the hose from the compressor.

regulated outlet gauge will be incorrect. This gauge ONLY  
indicates the correct pressure while air is being discharged  
from the outlet.  
4. To stop the compressor, push the On/Off switch down.  
Operation  
1.The pressure in the tank is controlled by the action  
of the pressure switch located under the pressure  
switch cover (2). When the set maximum pressure is  
reached the pressure switch activates and the motor  
is switched off. The pressure then decreases as the air  
is used by the connected tool until the set minimum  
pressure is reached after which the pressure switch  
causes the motor to switch on again. The operator of  
the compressor should be well aware that during use of  
the compressor the motor will start and stop under the  
influence of the rising or falling pressure in the tank.  
The motor will start without any warning.  
2.The maximum and minimum pressures are factory set  
and the operator should not try to change them.  
3.All accessories are  
connected to the regulated  
outlet valve (6).  
5. 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:  
Press down the on/off switch (3).  
Wait for the pressurised air to bleed from the release  
valve under the pressure switch cover (2).  
NOTE. When you press the button down you should hear  
a short air discharge (Approx 1/2 second).  
Switch off the electrical  
power supply and remove  
the electrical plug.  
Pull the ring on the safety  
valve (8) to ensure all the  
pressurised air is released  
from the tank, or open the  
drain cock to release the  
pressure from the tank.  
4.The pressure of the  
regulated outlet, as shown  
on the regulated outlet  
pressure gauge (7), can  
be changed by turning the  
regulating knob (5).  
WARNINGS.  
1. Never attempt to remove any part of the compressor  
whilst the tank is under pressure.  
2. Never attempt to remove any electrical component  
whilst the compressor is connected to the power  
supply. Switch off the power and remove the electrical  
plug.  
NOTE. To obtain the correct output reading on the  
regulated output gauge, 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 through the  
accessory being used.  
To increase the air pressure, rotate the regulating valve  
clockwise. To decrease the pressure, rotate the regulating  
valve anti-clockwise.  
3. Do not adjust the safety valve.  
4. Do not use an electrical extension cable.  
5. If the release valve under the pressure switch cover  
(2) fails to operate when the on/off button is pressed  
down, switch the power supply off and determine the  
nature of the fault.  
6. Ensure that the lubricating oil is clean and that the oil  
level is maintained at the mid point of the red circle in
