ADDITIONAL SAFETY INSTRUCTIONS FOR SAFETY VALVES
Information: The safety valves are designed and constructed for
use exclusively with compressed air, free from impurities. The
materials used in construction are suitable for operating the valve
at the rated pressure and temperatures. The Viton or NBR gasket
conserves the resistance characteristics, even in prolonged use.
The valve caulking impedes calibration modification; tampering
with the valve and/or changing the constructor’s calibration is
forbidden.
Installation: Valve installation must be performed exclusively by
technically prepared persons, who are responsible and in good
health. Checking the integrity of the valve before installation is
obligatory. Also, check that the valve pressure is no greater than
the operating pressure of the tank or of the system to protect.
Check that the discharge flow rate of the valve is greater than the
quantity of the air to discharge. The safety valve must be
positioned directly on the tank in a vertical position, in a dry,
accessible place protected against the weather and far away from
liquids or condensation. It must be positioned so as to have
sufficient space all around for correct air discharge, without
causing damage to persons and/or things. The valve rod must
therefore be free in its movement when discharging. The
connection between the valve and the part to be protected must
be free from all kinds of choking and be as short as possible so as
not to reduce the discharge flow rate of the valve itself. The
connection passage area must be greater than the valve orifice
area. During installation, screw on the valve with a torque
spanner using the hexagonal part of the body. Apply a maximum
torque of 30Nm, paying attention not to cause any deformation;
using pincers, pliers, hammers or tools other than a hexagonal
spanner is forbidden. Check that the inlet hole and the shutter
are not blocked by glue, teflon or similar materials that could
bind the shutter or other functional components. If the value is
replaced, the compressor air contained in the system must be
discharged first. We decline all responsibility for damage caused
to persons and/or things due to failure to observe these
instructions.
Maintenance and inspection: The valve must not be subjected
to knocks which may cause deformities. It is obligatory for
qualified technicians to make sure that the safety valve functions
correctly at least once a year. Valves equipped with a ring must
be tested while pressurised to between 80-90% of the calibration
value. Pull the ring and release immediately. During the test the
valve must definitely open and discharge the air and re-close
immediately when the ring is released. It is absolutely necessary
to carry out this procedure with the utmost caution because this
type of job can be dangerous if adequate safety measures are not
taken; wear goggles, a head set and anything else necessary to
protect against noise, jets of air, etc. which may be discharged
from the valve.

ADDITIONAL SAFETY INSTRUCTIONS FOR PRESSURE
VESSELS
This pressure tank is mainly intended for static use. It can only be
charged with natural air within temperature and pressure limits
as specified on the manufacturer’s plate and declaration of
conformity.
Ensure that tank safety and control devices are efficient and
flawless. When replaced, the tank should not be under pressure.
Drain the condensate off the tank every day.
Check for signs of inner corrosion at regular intervals. Tank walls
should have a minimum thickness of 1.5mm (DA25/206)/2.0mm
(DA50/206).
Any kind of welding to this tank is forbidden.
The user shall comply with laws on pressure vessel operation in
force in the country in which the tank is operated.
The construction is mainly effected for permanent load by
internal pressure. Cyclic loads are not considered, only for a
range of 10% PS.

WHEELS AND ANTI-VIBRATION FOOT
DA50/346TV
Pass the bolt through the wheel and then insert the spacer on the underside of the wheel of
the compressor’s frame and fit the washer and secure with the nut. To mount the foot pass the
bolt through the bracket on the bottom of the tank and then through the rubber anti-vibration
foot into the front position.
AIR FILTER
If not already fitted, remove the transit bung from the top of the head and screw the air filter
assembly into position.
OIL LEVEL
NOTE: For transportation purposes the oil level dipstick is supplied in a separate bag.
ATTENTION! Remove the plastic bung from the crankcase, fill with oil and replace it
with the dipstick.
NOTE: The plastic bung should be retained for future use should it be necessary to transport
the unit.
ATTENTION! Prior to any operation check the oil level ranges between max. and min. on the
dipstick.
If necessary adjust the level (see page 10).
WARNING: Never operate the compressor with only the plastic transportation bung fitted.
Under normal use internal pressure can expel the bung along with oil from the head, possibly
leading to damage
Positioning
In order to ensure proper air flow to the ventilation grills ensure the compressor is at least
50cm from any obstacles which may impede air from flowing correctly.

OPERATION AND USE
- ON/OFF SWITCH (Figs.1.& 2.):
- NOTE: Prior to connecting the compressor to the
power supply ensure the pressure switch is in the off
position.
On initial start-up open the reservoir condensate drain
bung (A)†, adjust the pressure regulator (B) to the
maximum pressure.
† Unscrew bung anticlockwise to open
valve.
Pull the pressure switch (C) up to start the
compressor.
Allow the machine to run for 10 minutes with the air
escaping from the reservoir tank before closing the
drain bung (A). Ensure the compressor is switched off
before doing this. Ensure the tank pressure reaches
8 bar as indicated on gauge (D) before the pressure
switch shuts off the motor.
- NOTE: When the drain bung is closed the tone from
the motor will change.
The compressor motor will automatically restart when
the tank pressure drops to approx. 2 bar less than the
maximum pressure.
- ATTENTION: Never stop the compressor using the
mains connection. Always switch off the
compressor by pressing the pressure switch button
down. The compressed air will be vented from the
head and allowing an easy re-start.
- NOTE: During correct operation a whistle of
compressed air escaping/releasing will be heard when
the motor stops and a protracted whistle (approx.
20-30 seconds) when ever the compressor is started
with no pressure in the tank.

MAINTENANCE
- NOTE: Remove the plug from the socket before carrying out adjustment, servicing or
maintenance.
In order to maintain the compressor to it’s optimum, periodical service checks must be carried
out routinely. Allowances should be made to adjust the time scale for machines in occasional
service with the exception of the safety valve which must be inspected by a qualified service
agent every 12 months regardless of use.
- AFTER THE FIRST 50 HOURS SERVICE
Ensure that all fixings have remained tight, in particularly on the head and crankcase.
Replace the crankcase oil with one from the recommended oil list from below.
- RECOMMENDED OILS:

- NOTE: Never mix different brand or grade oil together.
- DAILY CHECKS:
• Before every use check the airline filter/regulator/seperator. Fill the lubrication level up,
empty any collected condensate and adjust the line pressure to the accessory as necessary.
• After every use adjust the line pressure back to zero.
- WEEKLY CHECKS:
• At least once a week the build up of condensate should be drained from the tank†.
† In the absence of a filter/regulator/separator to ensure a clean/dry lubricated air
supply the condensate should be drained before each use.
Open the reservoir condensate drain bung fully before tilting the compressor to ensure all
condensate is drained. Collect the moisture in a suitable container.
As the compressor is oil free the condensate will contain no lubricate/polutants so requires no
special disposal.
Finally close the bung, pressurise the tank fully and switch off the compressor. Open the bung
to remove any remaining condensate under pressure.
- NOTE: Ear defenders and safety goggles must be worn.
- 10 -
MAINTENANCE
- MONTHLY CHECKS (Fig.5 & 6.):
- Remove the air filter housing to access the foam filter
element.
- Remove the foam filter to replace or clean it.
Rinse the filter with water. Make certain the element is
completely dry prior to refitting.
- ATTENTION: Never attempt to run the compressor
without the filter element fitted as dust or foreign
bodies can enter the pump unit resulting in
serious damage.
This must be carried out more frequently if the
compressor is operating in a dusty environment.
The motor must be correctly ventilated during
operation. For this reason avoid blocking the air inlets.
After use disconnect the tool from the power supply
and vacuum the ventilation slots.
If replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order
to avoid a safety hazard.
- REPLACING/TOPPING UP OIL (Fig.7 & 8.):
Remove the dipstick and with a suitable spanner
lossen and remove the crankcase bung. Collect the
used oil in a container to be disposed of in the correct
manner according to european regulations.
