Technical Data
Assembly
Delivered items
The impact wrenches are delivered with closing cap and
quick-change nipple provided, but without tool bits.
The impact wrench kit contains the impact wrench
0 607 450 628 as well as a spindle extension (90 mm)
and 5 impact sockets (size 14 mm, 17 mm, 19 mm,
21 mm and 22 mm).
Connection to the Air Supply
f
Pay attention that the air pressure is not
below 6.3 bar (91 psi), as the pneumatic tool
is designed for this operating pressure.
For maximum performance, the inner hose diameter
sizes as well as the connection threads must correspond
with the values listed in the table “Technical Data”. To
maintain full performance, use only hoses with a maxi-
mum length of 4 meters.
The supplied air must be free of foreign material and
moisture to protect the pneumatic tool from damage,
contamination, and rust.
Note:
The use of a compressed air maintenance unit is
necessary. This ensures optimum functioning of com-
pressed air tools.
Observe the operating instructions of the maintenance
unit.
All fittings, connecting lines, and hoses must be dimen-
sioned for the required air pressure and volume.
Avoid restrictions in the air supply resulting from, e.g.,
pinching, kinking, or stretching!
In case of doubt, measure the pressure with a pressure
gauge at the air inlet with the pneumatic tool switched
on.
