3.3. HS and SW quick coupler with sensor
The HS and SW quick coupler with sensor monitors whether or not the quick coupler is in
the open position. The alarm output is connected to a QLM module mounted on the stick.
It uses sound and light warning signals when the tool’s locking cylinder is open, as the
primary safety purpose of the quick coupler is to protect personnel nearby. The operator
must inform personnel concerned what the alarms mean.
WARNING
Stop work immediately and begin troubleshooting if
the system warns of a faulty tool connection during
operation. Risk of personal injury and damage to
property.
CAUTION
Use hearing protection when close to or handling the
Q-Safe quick coupler when it is connected. Risk of
hearing damage.
