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.
Warranty
Provided the operating instructions have been followed, and the compressor has
been properly maintained, Bambi HT 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 Compressors 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.
• Compressed air is dangerous if
misused and can prove fatal. Avoid
any bodily contact with compressed
air.
• 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.
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.
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
Starting & Stopping
Plug the compressor into an outlet socket of nominal voltage.
All models other than HTS5
Switch the compressor on using the red button on top of the pressure switch.
The compressor will start running and automatically switch off at the preset pressure.
HTS5
Switch the compressor on by turning the red off/auto switch on the front of the case to
auto.
As air is used the pressure drops and the motor will restart at the preset pressure.
Approx 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 black knob [red on HT3 and HTS5] in a clockwise
direction; to decrease turn anti clockwise. On some models it is possible to lock the
setting by pushing the knob down until it “clicks” home.
On some models there are two pressure gauges.
The larger gauge indicates the air receiver pressure, the smaller gauge indicates the
air outlet pressure.
The pressure gauge on the HT3 and HTS5 indicates the air outlet pressure.
NOTE!
NEVER unplug the compressor when running. Always switch off using the red
button on the pressure switch or case to ensure the compressor discharges.
Failure to do so will cause damage and will invalidate your warranty.

Routine Maintenance
Refer to preventative maintenance section for frequency. [Page 4]
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.
The drain tap for the HTS5 is situated on the underside of the case.
Draining the Filter/Regulator Unit
(where fitted)
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.
The pressure relief valve on the HTS5 can be accessed by removing the case.
Note !
Isolate power supply before removing case.
Technical
We recommend the compressor has a maximum 50% duty cycle to prolong pump life.
Note !
The motor must never be allowed to run continuously otherwise it will overheat and
may become damaged.
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.
Check for -
• Drain tap not closed properly
• Air leaks on the pneumatic fittings
• Compressor not the correct size for the work load
• Cooling fan cover vent restricted
If problems persist contact your dealer.
