TIGHTENING TORQUES
CAUTION
Observe correct tightening torques!
Only torque wrenches tested (e.g.
biannually) regularly may be used.
The maximum permissible tolerance for
torque wrenches is +/- 4% of the respective
tightening torque (MA).
Use a torque wrench, otherwise screws are
usually overtightened, screws are
overstretched, threads are damaged
causing the screws to tear off! A secure
connection no longer ensured with the
wrong torque.
WARNING
Danger of confusing similar fitting series
and units!
Defective connections cannot resist
operating pressures and are therefore
ripped out suddenly. This can lead to severe
injury from parts being blown away and
hydraulic liquid leaking out.
The minor difference between lightweight (L)
and heavy (H) fitting series, for example, or
different units, e.g. metric or imperial, can
result in incorrect connections being made in
tube and hose systems.
Please check the types of connections used.
Only use original spare parts!
If you have any questions, please contact
SCHWING Customer Service.
WARNING
Faulty mounting!
High-strength screw-type connections must
be pre-stressed with a specific tightening
torque.
Tightening torques depend, among other
things, on the screw and nut type, thread,
surface treatment and lubrication.
