Draining The Pressure Tank
WARNING!
ALWAYS MAKE SURE THE COMPRESSOR
IS TURNED OFF AND THE TANK PRESSURE GAUGE
SHOWS 0 PSI BEFORE OPENING THE DRAIN VALVE.
TAKE CARE WHEN DISCHARGING AIR THROUGH THE
DRAIN VALVE OR AIR OUTLETS. THE DISCHARGED AIR
CAN CAUSE DUST, STONES, OR ANY OTHER FOREIGN
PARTICLES TO BE BLOWN THROUGH THE AIR AT HIGH
PRESSURE.
Air in the compressor tank causes water to accumulate. This must
be drained off frequently to prevent corrosion and damage to the
unit.
This should be performed after each use and prior to the
next use.
1. Turn the drain valve plug
clockwise to open it.
2. Allow all of the water in the tank to drain out.
3. Replace the drain valve plug.
Note:
The tank will not pressurise while the drain valve is open.
Cleaning The Air Filters
The air filters prevent dust and dirt being drawn in. It is
essential to clean these filters at least after every 100 hours in
service. Clogged air filters will decrease the performance of the
compressor drastically.
1. Allow the compressor to run and build up pressurised air in the
tank. Once the motor has stopped running, turn the compressor
off and disconnect it from the power supply.
2. With an air hose and blow gun connected to the regulated
pressure outlet, turn the pressure regulator until the regulated
pressure gauge shows a pressure of around 3bar.
3. Unscrew the lid of the air
filter.
4. Remove the paper filter
from the housing, tap it and
spray it with the blow gun to
remove any dirt. Re-insert it
into the housing.
5. Re-attach the lid.

Symptom
Possible Cause
Suggested Solution
The compressor does
not start
Compressor has
reached cut-out
pressure
Compressor will
automatically start
once below the cut-in
pressure
No power supply
Check the power supply,
the power plug and the
socket-outlet
Insufficient supply
power
Reduce length of
extension lead
Outside temperature
is too low
Never operate with an
outside temperature of
below 5°C
Motor is overheated Allow the motor to cool
down. If necessary,
remedy the cause of the
overheating
The compressor
starts but there is no
pressure
The seals are
damaged
Check the seals and
have any damaged seals
replaced by a service
centre
The drainage valve
leaks
Ensure it is properly
closed
The compressor
starts, pressure
is shown on the
pressure gauge, but
no pressure to the
air tool
Loose hose
connections
Check the compressed
air hose and tools and
replace if necessary
Leak in a quick-lock
coupling
Check the quick-lock
coupling and replace if
necessary
Insufficient pressure
set on the pressure
regulator
Open the pressure
regulator further
