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.
At no time must the oil temperature
be allowed to exceed 100°C.
Never tamper with the pressure relief
valve.
Never change the oil when the
compressor is still warm. Take
necessary precautions to avoid
contact with the skin.

Bambi SB42/46 compressor oil does not
contain hazardous components and is
not required to be labelled dangerous,
according to the Classification,
Packaging and Labelling of Dangerous
Substances regulation:
[CPL]Regulation 1984
Siting The Compressor
What you must do
Provide adequate protection from
the weather.
Site the compressor level in both
planes.
As larger models are heavy, ensure
the surface has sufficient load
bearing capacity.
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. 35°C
should be regarded as the 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.

Electrical Connections
All 220/240 volt compressors, except Model 225/1000 are supplied with a moulded
plug in accordance with national standards.
Never remove the moulded plug.
Wired in accordance with European Standard –
Blue = neutral Brown = live Yellow & Green Stripe = earth
Model 225/1000 requires a dedicated 20 amp power supply.

Operation
Refer to exploded parts diagrams and illustrations when reading this section.
Oil level
Your Bambi compressor is shipped without oil for transit. Before use you must fill the
motor to the correct level.
Model 35/20
Remove oil filler plug - see fig 1
Pour oil into motor until correct level is reached - indicated on the oil sight glass,
approx 500cc - see fig 2
Refit the oil filler plug - but do not over-tighten.
Models 75/80 to 225/1000
Remove air intake filter housing by pulling gently out of intake tube - see fig 9
Pour oil into motor through the tube until the correct level is reached indicated on
the oil sight glass, approx 900cc - see fig 2
Refit air intake filter to intake tube
Note!
Always use Bambi SB42/46 compressor oil. Failure to do so will invalidate your warranty.
Starting & Stopping
Plug the compressor into an outlet socket of nominal
voltage and fitted with a 13amp fuse.
Note!
Model 225/1000 requires a dedicated 20 amp power supply.
Switch the compressor on using the red button on top of the pressure switch. Pull
knob up to switch on, push down to switch off – see fig 3.
The compressor will start running and automatically switch off at the preset pressure.
As air is used the pressure drops and the motor will restart at the preset pressure.
Approx 2 Bar differential.
Note!
Never tamper with the pressure switch settings, these are factory set.
Adjusting Outlet Pressure
Use the filter regulator to adjust the outlet pressure. The 40mm pressure gauge
indicates the selected pressure. To increase line pressure rotate the black knob on
top of the filter regulator in a clockwise manner, to decrease turn anti clockwise. It is
possible to lock the setting by pushing the knob down until it “clicks” home – see fig 4.

Routine Maintenance
Draining the Air Receiver
Drain 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 – see figs 7 & 8.
Close drain tap when all water has drained off.
Do not overtighten, this will damage the tap seal.
Automatic drains where fitted do not require draining, however the drain bottle will
require emptying.
Draining the Filter/Regulator Unit
Slowly open the drain screw provided to allow water to flow out – see fig 5.
Close the drain screw when all water has drained off.
Note !
The waste 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
– see fig 6.
Technical
The compressor has a maximum 50% duty cycle. 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.
Note !
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
