TO STOP THE COMPRESSOR:
Push down on the pressure switch (
C)
button as shown in (
Fig.11
). Move the
SA1
&
SA2
switches to the
OFF
position. Move the power switch (
D
) to the
OFF
position to
disconnect from the supply.
WARNING:
Never stop the compressor using the mains connection. Always turn off the
compressor by pressing the pressure switch button down first.
This way the compressed air will be vented from the head and allowing an easy re-start
and unnecessary damage to the motor can be prevented.
OVERLOAD CUT-OUT
The compressor is equipped with an overload cut out shown at
E
(
Fig.13
) which operates
as a safety device to protect the motor.
Should a fault occur and begin to overheat the motor the overload cut out will
automatically engage, cutting the power supply to the compressor.
NOTE:
A secondary thermal cutout
RESET
button
(F)
is located in the control box (see
Fig.13
).
In the event of an overload cut-out, please allow
5 minutes
for the machine to cool prior
to attempting to reset the overload cut-out.
If, after resetting the overload cut-out, the overload is activated again, switch off the
machine, disconnect the power supply and contact your Jefferson Dealer for advice.
EFFICIENT OPERATION
For efficient operation of the compressor at full working load and at maximum
operating pressure, ensure that the temperature of the working environment does
not 25°C.
We recommend that you use the compressor at 70% maximum duty per hour
at full load as this will help to ensure efficient operation of the equipment in the
long-term.
PNEUMATIC CONNECTIONS
Ensure that all pneumatic connections used for compressed air have maximum
pressure ratings that are compatible for use with the compressor.
Any equipment
damage caused by misuse are not covered under warranty.
