Do not let others in the vicinity make contact with the
tool or extension cord.
4. Store tools safely. When not in use, tools should be
locked up out of reach.
5. Do not force the tool. The tool will do the job better
and safer working at the rate for which it was
designed.
6. Use the correct tool for the job. Do not force small
tools or attachments to do the job best handled by a
heavier duty tool. Never use a tool for a purpose for
which it was not intended.
7. Dress correctly. Do not wear loose clothing or
jewellery. They can be caught in moving parts. Rubber
gloves and non-slip footwear are recommended when
working outdoors. If you have long hair, wear a
protective hair covering.
8. Use safety accessories. Safety glasses and earmuffs
should always be worn. A face or dust mask is also
required if the sanding operation creates dust.
9. Do not abuse the power cord. Never pull the cord to
disconnect the tool from the power point. Keep the
cord away from heat, oil and sharp edges.
10. Secure the work piece. Use clamps or a vice to hold
the work piece. It is safer than using your hand and
frees both hands to operate the tool.
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.
14. Remove adjusting keys and wrenches. Check to see
that keys and adjusting wrenches are removed from
the tool before switching on.
15. Avoid unintentional starting. Always check that the
switch is in the OFF position before plugging in the
tool to the power supply. Do not carry a plugged in
tool with your finger on the switch.
16. Use outdoor rated extension cords. When a tool is
used outdoors, use only extension cords that are
intended for outdoor use and are so marked.
5
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.
20. Use only approved parts. When servicing, use only
identical replacement parts. Use an authorised service
facility to fit replacement parts.
Additional safety rules for air compressors
Warnings. 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 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.
• Never directly inhale the compressed air produced by a
compressor and do not use it for charging breathing
tanks.
• 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.
• 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
6
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.
• 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/
• After long working periods external metal parts could be
hot.
• 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.
The manufacturer shall not be liable for any changes
made to the tool nor for any damage resulting from such
changes.
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.

Unpacking
Due to modern mass production techniques, it is unlikely
that your GMC Power Tool is faulty or that a part is
missing. If you find anything wrong, do not operate the
tool until the parts have been replaced or the fault has
been rectified. Failure to do so could result in serious
personal injury.
Assembly
The handle of the AC40L model must be fitted in the
following manner:
1. Loosen the grub screw in each of the handle fixing
holes.
2. Insert the two ends of the handle into the fixing holes.
3. Tighten the grub screws to secure the handle in place.
Wheels
Fit the wheels as follows:
• for the 24 litre compressor, push each wheel firmly onto
the axle until it "snaps" into position.
• for the 40 litre compressor, first insert an axle pin
through the wheel and then through the hole in the
bracket under the tank. Next, fit the spacer on the axle
pin followed by the flat washer, split washer and nut.
Tighten the nut. Repeat for the second wheel.
Rubber feet
Fit the two rubber feet on the bracket on the front
underside of the tank using the screws, washers and nuts
supplied.
Warning. The air compressor must be filled with oil before
first use.
To prevent possible spillage of oil during transport, the
compressor oil is supplied in a separate container. It must
be added to the compressor before turning the compressor
on. Failure to add the oil will cause non-repairable
damage to the compressor and will void the warranty.
1. Remove the plastic oil filling cap (15) located on the
top of the crank case of the compressor housing.
2. Use the oil supplied to fill the crank case until the oil
level as seen in the oil level glass (17) is up to the mid
point of the red circle.
3. Replace the oil filling cap (15). Ensure the cap is fully
fitted and firmly in position.
10
Warning. The air filter must be added before first use.
Failure to fit the air filter will damage the compressor and
will void the warranty.
4. Remove the plastic air filter plug from the head of the
compressor.
5. Carefully screw the air filter assembly (16) into the
threaded hole taking care not to cross the thread.
6. Tighten firmly by hand only.
Pre-start routine
1. Ensure that the location for the compressor is clean,
dry and well ventilated.
2. Ensure the crank case has been filled with oil and is at
the correct level, and the air filter has been fitted.
3. Open the direct output valve (4) and the regulated
output valve (7).
Open the valve by sliding the outer sleeve fully forward.
To close the valve, slide the outer sleeve backward
towards the compressor.
4. Start the compressor by following the procedure in the
section “To start and stop the compressor”. For the first
time of operation, run the compressor for 10 min with
no load to ensure all parts are well lubricated.
Warning. Be aware that presurised air will be discharged
from the two outlets and care should be taken that this
discharge is not directed towards you the operator, or
other persons within the area.
To start & stop the compressor
1. Check the rating label on
the compressor indicates
230V–240V.
2. Plug in the mains cable of
the compressor to a
standard 240V houshold
power point and turn on.
3. To start the compressor,
lift the On/Off switch (3)
on the pressure switch
cover (2).
4. To stop the compressor,
push the On/Off switch
(3) down.
11
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 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. You can connect an accessory to either the direct outlet
valve (4) and/or the regulated outlet valve (7). The
regulated outlet is the one on the left when you face
the front of the compressor.
4. The pressure of the
regulated outlet [as shown
on the regulated outlet
pressure gauge (8)] can
be changed by turning the
regulating knob (6).
Rotate the knob clockwise
to increase pressure and
anti-clockwise to decrease
pressure.
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.
To increase the air pressure, rotate the regulating valve
clockwise. To decrease the pressure, rotate the regulating
valve 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 discharge air from the right hand (opposite) outlet
(4) is not regulated and will discharge air at tank
pressure. The gauge for this outlet (5) will show the
correct pressure in the tank with or without the air being
discharged.
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 tank 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 (9) to ensure all the
pressurised air is released
from the tank, or open the
drain cock to release the
pressure from the tank.
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.
3. Do not adjust the safety valve.
4. Do not use an electrical extension cable.
