6. Preparing the Compressor
6.2 Topping Up the Oil
CAUTION! This product is NOT shipped with oil.
Oil MUST be added to the product before rst
use and checked and topped up as appropriate
before every use thereafter.
ISO grade 22–32 (SAE grade 5W–15W) monograde oil
should be use used with this product.
Important: ALWAYS position the compressor on a level
surface when checking the oil level.
Important: DO NOT allow the oil level to drop below the
minimum level.

Fig.
(7) (8)
1. Pull the oil ller bung (7) from the aperture.
2. Using a funnel, pour oil into the reservoir and observe
the level through the viewing window (8).
3. When the max level is reached, replace the oil ller
bung securely.
Important: The highest and lowest points of the
centremost circle in the viewing window indicate the
minimum and maximum permissible oil levels.
CAUTION! DO NOT overll the oil as the
excess may ood the airline or damage
internal components of the compressor.
6.3 Draining Moisture from the Tank
Over time, compressed air will create moisture within the
reservoir. This moisture can mix with the air supply and
may cause signicant corrosion to connected air tools or
to the reservoir tank itself. To prevent this, the reservoir
tank should be drained before and after EVERY use.
WARNING! Keep hands and other body parts
away from the drain bung while draining the
moisture from the tank as it may be ejected with
considerable force.
To drain the reservoir:
1. Without connecting an air line, start the compressor
to generate low internal pressure within the reservoir
tank (see 7.2 Switching the Compressor On and
O).
Important: DO NOT apply excess pressure to expel
moisture from the tank. The tank pressure should
NOT exceed 2bar when draining the moisture.
2. Place a container beneath the drain bung (2) on the
underside of the tank.
3. Once it has pressurised, carefully loosen the drain
bung and allow the air to force any residual moisture
from the tank.
4. When no more moisture or air is expelled, clean
around the opening and reinstall the drain bung.

6. Preparing the Compressor
6.4 Connecting an Air Line or Tool
CAUTION! ALWAYS check the air line
requirements for any tools or air lines connected
to this device. DO NOT use this compressor with
any incompatible air line or tool.
WARNING! ALWAYS ensure that the air line is
interrupted and the output pressure is minimal
when connecting an air line or tool. DO NOT
attempt to connect an air line or tool if air is
escaping from the compressor.
Important: ALWAYS ensure that the pressure switch (12)
is in the o (depressed) position before attaching or
detaching an air line or tool. Draper Tools recommends
pressurising the tank rst, leaving the output pressure
regulator (11) in its lowest position, then connecting the
air line and tool.
This device is tted with a female Euro-style air line
adaptor. To connect an air line or tool, insert a male
Euro-style air line coupling attached to the item into the
outlet (9) and allow the collar to snap back to secure it.
Once the air line is connected, the output pressure may
be set; see 7.3 Setting the Output Pressure.
7 Fig.
(9)
Important: Draper Tools strongly recommends that this
compressor is used with an in-line water separator in the
air line to protect your connected tools and any sprayed
materials. An in-line lubricator should be used for most
air tools, excluding spray guns. An in-line regulator
should also be used for greater control over the airline
pressure. ALWAYS adhere to the manufacturer
instructions of any accessories.
Before connecting a tool to the air line, run the
compressor with the air line connected and open to blow
any residual moisture from the line.
When using an air tool with a hose over 25ft long, Draper
Tools recommends increasing the bore of the hose to the
next largest available size (i.e. increase 3 ⁄ 8" to 1 ⁄ 2").
This will ensure adequate pressure and volume of air to
power the tool.
Draper Tools recommends that PTFE tape is wrapped
around all threaded connections along the air line for a
better airtight seal. For best results, wrap the tape in the
opposite direction to the thread.
Important: Draper Tools recommends using a suitable
whip hose between the connected tool and the air line to
reduce vibrations at the tool. Take care as whipping
hoses may cause injury.
To detach the connection from the compressor outlet,
rotate the output pressure regulator fully anticlockwise
and allow the output pressure gauge to drop to zero.
Then pull down the collar to eject the connected item.
Important: ALWAYS rst allow the outlet pressure to
drop to zero and grip the air line when detaching it from
the compressor to avoid injury from whipping hoses.

7. Operating Instructions
Important: Before operating this product, read and
understand all the safety instructions listed in this
manual. The compressor MUST be correctly prepared
before use.
WARNING! The reservoir tank and motor may
become hot during use. DO NOT touch heated
parts of the product until it has been switched
o and allowed to cool thoroughly.
7.1 First-Time Use
When using the compressor for the rst time, it must be
run until fully pressurised to ensure that the motor stops
automatically when the maximum pressure is reached.
Ensure that both the drain bung (2) and outlet (9) are
closed before pressurising the tank.
If the maximum achievable pressure does not match the
rated maximum, depressurise the tank and test again. If
the result is consistently incorrect, there may be moisture
in the reservoir tank.
Important: Check the maximum pressure periodically to
ensure no leakages or moisture build-up are present.
7.2 Switching the Compressor On and O
Important: This product is NOT rated for continuous use.
The compressor motor may activate no more than ve
times within one hour of use. ALWAYS allow the device
to rest and cool before reuse.
Important: If the compressor is being used for the rst
time after unboxing, perform the rst-time use procedure
(see 7.1 First-Time Use) before using the product.
CAUTION! The correct procedure for switching
the compressor on and o MUST be observed.
Failure to perform the steps in the correct order
may cause signicant damage to the product.
The supply of compressed air may still be used when the
motor is switched o but the reservoir tank will not
repressurise as air is used.
8 Fig.
(12)
Switching the Compressor On
1. Ensure that the following have occurred:
a. The compressor is correctly assembled and
prepared.
b. The compressor pressure switch (12) is in the o
(depressed) position.
c. The output pressure regulator (11) is set to its
lowest position.
2. Connect the compressor to mains power.
3. Activate the mains power supply.
Important: A live power supply MUST be connected
to the compressor BEFORE the compressor is
switched on at the motor.
4. Grip the pressure switch and pull it upwards to switch
on the compressor.
5. The motor will activate and begin to pressurise the
reservoir tank.
The motor will stop automatically when the maximum
tank pressure is reached. To release air into the air line,
rotate the output pressure regulator until the desired
pressure is indicated on the output pressure gauge (10).
While the pressure switch remains in the on (raised)
position, the motor will automatically restart when the
tank pressure drops below the rated cut-in value.
Important: DO NOT allow this to occur more than ve
times within the same 60 minute period.
Switching the Compressor O
1. If the operation is complete and the compressor will
be stored, decompress the reservoir tank (see 7.4
Depressurising the Reservoir Tank).
2. Push the pressure switch (12) down into the o
(depressed) position.

CAUTION! NEVER unplug the switch or
disable the mains power supply to switch o
the compressor.
7.3 Setting the Output Pressure
Important: This compressor delivers a maximum output
pressure of 8bar (116psi). NEVER exceed the maximum
operating pressure of any component of the connected
air line.
The output pressure can be set by rotating the output
pressure regulator (11) and monitored using the output
pressure gauge (10). The current output pressure can
only be viewed when the tank is pressurised and air is
escaping via the outlet.
9 Fig.
(10)
(11)
Important: ALWAYS use the minimum outlet pressure
required for the operation. Use of excessive pressure will
require the compressor to operate and rest more
frequently and may cause the operation to take longer.
• To increase the output pressure, rotate the output
pressure regulator clockwise.
• To decrease the output pressure, rotate the output
pressure regulator anticlockwise.
Important: When decreasing the pressure, Draper Tools
recommends lowering the pressure below the required level
and then adjusting upwards for a more accurate result.
Important: If the regulator is rotated to its full extent in
either direction, it may require a few turns before the
output pressure begins to change.
When the tank pressure reaches the same level as the
output pressure, both will decrease at the same rate
unless the tank is repressurised.
7.4 Depressurising the Reservoir Tank
Important: ALWAYS ensure that the compressor is
switched o and has completely cooled before
depressurising the reservoir tank.
The compressor tank must be depressurised when not in
use and before the product is moved or stored. To
depressurise the tank, use the attached tool to exhaust
the pressure.
7.5 Overload Cut-Out
The compressor is equipped with an integral overload
cut-out to protect the motor from overuse and
overheating. When this occurs, the overload cut-out is
activated automatically, shutting o the motor.
The overload cut-out is often activated as a result of the
following conditions:
• Low voltage to the compressor
• A clogged air lter
• Insucient ventilation
If the overload cut-out activates, switch o the machine
and disconnect it from the power supply. Allow it to cool
for at least 15 minutes before resuming.
If the overload cut-out continues to activate or will not
restart after having thoroughly cooled, switch o the
compressor and have it serviced by an authorised agent.
7.6 The Safety Valve
Important: The safety valve (16) has been set at the
factory to the value rated for this product. NEVER adjust
the safety valve.
The safety valve automatically relieves pressure within
the compressor tank if it exceeds the maximum rated
pressure for this device. If the safety valve does not
engage when the rated pressure is exceeded, the vale is
faulty and MUST be replaced.
If the safety valve is activated during use, switch o the
compressor and allow the pressure to return to an
acceptable level. Check the compressor for blockages or
damage before resuming.
If the safety valve is activated frequently, contact Draper
Tools for support.
Important: The safety valve MUST be replaced every 12
months, regardless of use, by an authorised service
agent; contact Draper Tools for support.

8.2 Air Filter Care
Clean the air lter chamber and element at least once a
month to ensure consistent airow into the compressor.
Increase the frequency of cleaning when working in
dusty environments.
WARNING! NEVER use petrol or solvents to
clean the air lter elements as they may damage
the lter or result in a re when the machine is
next used.
CAUTION! NEVER run the machine without the
air lter elements in place as this may cause the
engine to degrade rapidly.
