Operating Manual
Your Bambi Air Compressor is a precision engineered product.
By following these simple steps you will ensure years of trouble free use.
Parts & Service are available from your Bambi dealer.
It is important to quote Model, Type & Serial Number in all communications.
The substitution of parts not manufactured nor approved by Bambi can impair
performance, service life and create potential mechanical or personnel hazards and
will invalidate your warranty.
Bambi reserves the right to modify the contents of this operating booklet without
notice and the information is in no way binding on the company.
Provided the operating instructions have been followed, and the
compressor has been properly maintained, Bambi PT compressors are guaranteed
against faulty workmanship for a period of 1 year.
The air receiver is guaranteed for 5 years.
The guarantee does not cover damage by misuse, incorrect parts or service.
Contact Bambi Air Ltd or your retailer for further information.

1) Safety Precautions
What you must do:
• Read these instructions before using
your air compressor.
• Ensure the compressor has been
installed, electrically connected
and piped in by a properly qualified
person.
• Ensure the compressor is kept upright
at all times.
What you must not do:
• Do not attempt any maintenance on the
compressor until it has been isolated
from the power supply.
• Do not attempt any work on the
compressor until the air receiver and
pipe work systems are depressurised.
• During operation the motor will become
quite hot to the touch. Avoid contact
to prevent burns.
• Never tamper with the pressure relief
valve.
• Never lubricate the oil free motor or
pump assembly; this will cause
severe damage.
• Never obstruct cooling fans or outlet
vents.
• Compressed air is dangerous if
misused and can prove fatal. Avoid
any bodily contact with compressed air.
2) Siting The Compressor
What you must do:
• Provide adequate protection from the
weather.
• Site the compressor level in both
planes.
• Allow access for maintenance all
around the compressor.
• Site in a dry area, avoiding damp or
humid conditions. The site must be
dust free, well ventilated and have a
cool ambient temperature. 0 to 40°C
should be regarded as the minimum
and maximum allowable ambient.
What you must not do:
• Enclose the compressor or allow hot
air generated by the motor to re-
circulate around the compressor.
Ensure there is 30cm clearance
around the compressor
• Restrict air flow around the end cover
ventilation grilles.
Important !
These compressors generate heat.
Never restrict any of the ventilation grilles
otherwise serious damage may occur.
Electrical Connections
Where applicable, compressors are supplied with a moulded plug in accordance with
national standards.
Never remove the moulded plug.
The use of extension cables is not recommended as this may cause voltage drops
which can result in damage to the motor
110v/60Hz models wired in accordance
with US Standard –
White = neutral
Black = live,
Yellow = earth
220v/50Hz models wired in accordance
with European Standard –
Blue = neutral
Brown = live,
Yellow & Green Stripe = earth

Operation
NOTE!
Please ensure that the pump motor filter
is screwed in before operating the compressor.
Fit with intake tube pointing down
Installing airline:
The airline should be fitted to the Filter regulator outlet “A”
Starting & Stopping
Plug the compressor into an outlet socket of nominal voltage.
All models:
Switch the compressor on by turning the red control
on top of the pressure switch to the “Auto” position.
The compressor will run until the pressure in the receiver
is at 8 bar. It will then cut out.
As air is used the pressure drops and the motor will
restart at the preset pressure.
There is approximately a 2 Bar differential.
Note!
Each time the compressor switches off, you will hear
a short hiss of air. You are hearing the unloader valve discharging the residual
delivery pipe pressure.
This is normal.
Adjusting Outlet Pressure
Use the pressure regulator to adjust the outlet pressure.
To increase line pressure, rotate the knob in a clockwise
direction; to decrease turn anti clockwise.
It is possible to lock the setting by
pushing the knob down until it “clicks” home.
There are two pressure gauges on each model.
The larger gauge indicates the air receiver pressure, the smaller gauge indicates the
air outlet pressure.
NOTE!
NEVER unplug the compressor when running. Always switch off using the red
control on the pressure switch to ensure the compressor discharges.
Failure to do so will cause damage and will invalidate your warranty.

Routine Maintenance
Draining the Air Receiver
Drain water condensate from air receiver at a pressure of
no more than 2 Bar.
Slowly open the drain tap provided to allow water to flow out.
Close drain tap when all water has drained off.
Draining the Filter/Regulator Unit
Slowly open the drain screw provided to allow water to flow out.
Close drain screw when all water has drained off.
Note !
Waste water condensate must be handled in accordance with national environmental rules.
Check Pressure Relief Valve
Ensure the air receiver is not pressurised.
Unscrew the knurled end of the pressure relief valve until an audible “click” is heard.
Retighten without using excessive force.
Technical
We recommend the compressor has a maximum 65% duty cycle to prolong pump life.
Note !
The motor must never be allowed to run continuously otherwise it will overheat and
may become damaged. The duty cycle is calculated over 10 minutes, meaning that if
the motor runs continuously for 6.5 minutes it must then rest for 3.5 minutes.
Do not ignore air leaks. All air connections must be leak free to prevent the
compressor from over heating.
The compressor is fitted with a thermal overload. In the event of excessive
temperature, the motor will switch off. After about 50 minutes when the motor has
cooled it will automatically reset.
You must find the cause of the overload and rectify this before continuing to use the
compressor.
