AIR COMPRESSORS
DIRECT & BELT DRIVEN MANUALS

BEFORE STARTING COMPRESSOR, CHECK:
I. Compressor Pump Oil level using
(a) Dipstick (to level marked) or
(b) Sight glass (see fig 1).
II. Automatic control: Pressure switch ON/OFF
must be in the OFF position.
WARNING:
I. BEFORE STARTING COMPRESSOR, OPEN ALL OUTLET VALVES.
II. THE FOLLOWING START AND STOP INSTRUCTIONS MUST BE FOLLOWED
IN THE CORRCT SEQUENCE TO AVOID SERIOUS DAMAGE TO THE
COMPRESSOR/MOTOR.
TO START COMPRESSOR
I. Switch on isolator (mains supply).
II. Switch on pressure switch (lift knob or twist switch).
(See “GENERAL ARRANGEMENT” on page 6 item 14).
iii. Check rotation (Flywheel/Fan blows air over pump).
IV. Check that pressure does not exceed maximum working pressure (stamped on machine
plate), if the pressure exceeds the maximum working pressure stated, stop the machine
(see below), vent the system and contact the Adendorff Service Department.
TO STOP COMPRESSOR
I. Switch off at the pressure switch (push knob down or turn switch).
II. Isolate from the Mains Supply.
III. Drain air receiver (release drain tap).
WARNING: COMPRESSOR PUMPS, DELIVERY PIPES WILL REMAIN HOT FOR SOME
TIME AFTER USE.
WHY AIR-TOOLS?
• MOREECONOMICAL–Airtoolsare(almost)alwayscheaperthanelectrictoolswhen
comparing life span. Air tools have considerably lower maintenance requirements, meaning
less downtime.
• SAFERTHANELECTRICITY–Airtoolsaresafer,simplybecausetheycontainnoelectrical
elements meaning there is nothing that can go wrong electrically.
• WORKINGENVIROMENT-Airtoolsaremoresuitabletoworkinnumerousenvironments
such as damp areas and if there is imminent combustible gases around whereby electrical
tools are unable.
• ERGONOMICDESIGN–Airtoolsarelighterandsmallerwhencomparedtopowerorbattery
tools making them more ergonomically user friendly.

NOTE:
When starting compressors up
to and including 3 HP models,
an auto bleed valve will
operate and air will be heard
venting. This is quite normal
and should not cause concern.
The valve should close after
several seconds. Should it fail
to close, consult your local
Adendorff Branch.
DID YOU KNOW
What is the difference between
CFM- displacement and CFM
free air delivery (FAD)?
CFM DISPLACEMENT – this is the
actual measurement of the volume
of air that is been drawn into the
compressor pump.
CFM – FREE AIR DELIVERY (FAD)
– this is the actual volume of
air that is discharged from the
air compressor. CFM (FAD) is
typically a third less than the CFM
displacement – for example: if
the CFM displacement is rated
at 10 CFM then the CFM (FAD) is
probably around 6.6 CFM.
