5 Installation
•
Before connecting the air supply line to the screwdriver, clean the air pipe and the air
hose by slightly blowing air into the pipe/hose in order to remove any dirt particles.
Wear safety goggles!
•
Make sure, that all air lines have a sufficient cross-section ( chapter Technical Data)
and that there are no throttle areas, bends or kinks.
•
If the air supply line is longer than 2 meters, the next larger hose I.D. should be in-
stalled in order to avoid a loss of power.
•
This pneumatic screwdriver may be operated either with or without lubricated air. The
best performance is achieved by adding 1 – 2 drops of oil per 1 m³ of air consumption.
When operating with oil-free air, a performance reduction of up to 20% occurs and
maintenance requirements increases.
•
The air supply to the screwdriver has to be filtered.
•
The maintenance unit, the valves and the silencers have to be selected according to
the air consumption of the screwdriver ( chapter Technical Data). Install components,
which have a measurement that will limit the pressure drop – when measured from the
maintenance unit to the screwdriver – to less than 0.5 bar (7.25 PSI).
•
Use only lubricants approved by the manufacturer. We recommend:
special oil „DEPRAGOL“, order no. 790081 E (250 cm³ = 8.45 fl. oz).
•
Check flow-pressure at directly on the machine. The pressure regulator needs to be
adjusted to an airflow between 5.0 (71 PSI) and 6.3 bar (90 PSI). A higher pressure
leads to increased wear and tear. A lower pressure may lead to clutch not being able to
correctly shut-off the motor i.e. the preset torque will not be reached.
•
Connect the screwdriver as follows:
a) For standard operation, connect to a maintenance unit consisting of filter with water
separator, pressure regulator and oiler.
Air Consumption Thread Size Order No.
0,05 - 0,5 m³/min G 1/4 820454 A
0,15 – 1,5 m³/min G 1/2 820455 A
0,8 – 6,0 m³/min G 3/4 821608 A
b) For the use with minimal lubrication, connect to a filter-regulator consisting of filter
with water separator and pressure regulator, in connection with a point-of-use oiler
(order no. 378077 A, 1-fold)
Air Consumption Thread Size Order No.
0,05 - 0,5 m³/min G 1/4 822408 A
0,15 – 0,9 m³/min G 3/8 826981 A
0,15 – 1,5 m³/min G 1/2 822409 A
0,8 – 6,0 m³/min G 3/4 826982 A
c) For oil-free operation, connect to a filter-regulator consisting of filter with water se-
parator and pressure regulator.
Air Consumption Thread Size Order No.
0,05 - 0,5 m³/min G 1/4 822408 A
0,15 – 0,9 m³/min G 3/8 826981 A
0,15 – 1,5 m³/min G 1/2 822409 A
0,8 – 6,0 m³/min G 3/4 826982 A
Recommendation: The preferred lubricating method for screwdrivers mounted in fixtures,
brackets, machines etc. (in connection with controller) is method b) with point-of-use oiler.
We recommend attaching the screwdriver to a balancer ( Recommended Equipment).
