Sight glass
Check
Daily
The compressor oil level can be viewed through the sight
glass; the compressor must be on a level surface.
The top of the red dot indicates the full mark the bottom of
the red dot indicates the low mark. Always ensure that
the oil level is correct before operating the compressor.
Drain air tank
-
Daily
Section view of drain cock
The water in the tank comes from the atmosphere (it is
not made by the compressor), operating the
compressor on very humid days will result in
comparatively more water collecting in the tank than
operation on less humid days.
Loosen the drain nut and allow any condensed water
to escape, then close the drain cock again.
If the oil is low add Scorpion Compressor
oil or (equivalent to Aircol PD68)..

Pressure switch
On / Off
The pressure switch automatically controls the power to
the motor and operates the pressure relief valve. It also
allows for manual operation via the Push/Pull - On/Off
switch on top of the pressure switch.
The pressure switch is factory set to turn the compressor
on when the tank pressure drops below 85 psi and turn
itself off again when the tank is full.
You will notice that every time the unit reaches maximum
pressure and turns itself off (or if the unit is manually
turned off); there is a short release of high pressure air.
From under the pressure switch.
This is the pressure relief valve venting the air contained
within the pump and delivery tube (the pipe which
connects the compressor pump to the non-return valve
and tank). If this pressurized air is not vented before the
next startup It will cause excessive current draw which
may lead to motor failure. For this reason always turn the
compressor On and Off via the pressure switch
Pressure
switch
Any repairs to the pressure switch must be carried out by
qualified personnel.
The pressure relief
valve: Vents delivery
tube pressure when
the unit is turned off.
Non Return Valve:
Prevents back flow from the tank
The delivery tube:
Supplies compressed air
from the pump to the tank

Maximum Tilt
The maximum safe operating angle in any direction is
5° degrees.
Do not operate the compressor on inclines in excess of
5° degrees. Serious damage to pump components
may result from insufficient lubrication.
Never use the air compressor on a rooftop or elevated
position that could allow the unit to fall or be tipped
over.
Use additional air hose for elevated jobs.
Always turn the compressor off before moving.
Power supply
It is essential that the air compressor has an adequate
power supply.
Air compressors up to 2.2Hp should be operated on a
0 amp 240 volt circuit. Air compressors 2.5Hp or
larger should be run on a 5amp 240 volt circuit.
Always use a longer air hose before choosing to use an
extension lead, as low voltage could cause damage to
the motor. (Low voltage damage is not a warrantable
failure)
Expected use
:
In addition to pneumatic tools, your compressor may be connected to several accessories
suitable for blowing, washing and spraying. Please see the instructions provided with such accessories for
safe operation.
We recommend that the compressor duty cycle never exceed 50% and continuous operation never exceed 30
minutes.
Your belt driven compressor is intended for the following applications:
Domestic spray painting
Light industrial use, tyre inflation, Household, cleaning, pruning, drying
Air tools such as nail guns, staplers, spray guns, impact tools, etc.

Belt Drive Compressors / Single Phase

•Should you intend to use an air tool for a long durations ensure that the output of the compressor
(known as its FAD or Free Air Delivery) well exceeds the air consumption of the tool being used.
•Remember that your compressor has been designed with a 50% duty cycle in mind; continuous
operation may cause it to overheat and result in serious mechanical damage to components. You should
consider a larger or screw type compressor for long term or continuous duty applications.
•Use extension cords sparingly - and only use ones with an adequate current rating. Using an ordinary
(light duty) extension lead on a compressor can cause voltage drop, overheating the motor and
leading to appliance damage or even fire.
•As your Compressor has an air cooled motor as well as an air cooled pump which draws in atmospheric
air for cooling, it is important not to run the compressor in confined areas with poor ventilation or
elevated temperatures. Never use on loose surfaces such as dirt, dust or sand, otherwise abrasive
particles will be sucked into the air stream and cause the premature wear of components.
•Your air compressor is not water proof; do not attempt to use or store it in the rain, snow or any other
environment with extreme conditions. It has been designed for use and storage indoors.
•Used and maintained correctly, your compressor will provide many years of reliable service.
•Your Compressor has been manufactured to a high standard in order to ensure a long service life.
Ultimately the realization of the intended service life requires the operator to observe all instructions and
servicing requirements as described in this manual.
•Always wear approved safety glasses with side shields when using compressed air. Never point any
nozzle or sprayer toward any part of the body or at other people or animals.
•Do not operate the air compressor if any guards or covers are missing, damaged or not installed
correctly. Ensure all maintenance is carried out by qualified personal.
•Never allow children or untrained personal to “play” with compressed air.
The Compressors are equipped with an overload cut-out
(E) which operates as a safety device to protect the motor.
When the motor overheats, because of any electrical or
physical overload, the cut-out switch automatically
releases and cuts off power, thus preventing the motor
from being damaged. If tripped, wait a few (about 5)
minutes before resetting the device, then restart again.
If you restart the compressor and the overload safety
switch releases again, turn the main switch OFF, unplug
the equipment, and contact an Authorized Service Centre.

2.2 Preparation before Starting
Unpacking
Depending from the model, the compressor can be supplied on a wooden
pallet and protected by a top cover; or in a carton box. Wear safety gloves
and cut straps with scissors and withdraw any staples with long nose pliers
and open the top cardboard flaps from the machine top, or lift the compressor
with the help of mechanical assistance. When handling compressors with
tanks holding over 50 litres and be sure to keep the machine well balanced at
all times. Hoist the compressor using suitable lifting power. Clear the
area of any possible hindrance, These compressors should be handled by
skilled personnel trained to operate lifting equipment.
Fit the wheels and/or the anti-vibrating
elements. Once the compressor is in
the designated place of installation, fit
the vibration dampers and/or the
wheels supplied with it.. Pay attention
to the accessories contained in the
packing and verify the integrity of your
compressor. Carefully lift the
compressor and place it on the work
surface.
We recommend that you store the
packaging for the duration of the
warranty period. If necessary, it will be
easier to return the compressor to the
service centre.
Run in procedure
When starting the compressor for the first time leave the air compressor run for 0 minutes with the air cock completely
open. After 0 minutes check that the drain cock is closed and shut the main air cock. Make sure that the compressor
stops automatically once its maximum pressure is reached. The compressor will start again once the pressure drops
below the minimum threshold pressure (approx. 2bar (30psi) lower than the cutoff pressure).
*Note: All SP Compressors are delivered only after a successful testing period at the factory.
For the long life of your compressor it is recommended that you drain and replace the pump lubricant after 10 hours of
use, Drain the oil while it is still warm this will help remove any abrasive particles loosened from the initial run in period.
Replace pump oil with Scorpion Compressor oil AC-68.
