1.4 Use the Lock-out padlock
General description
When a service engineer performs maintenance for the tape cutter or other parts on the machine,
a bystander may accidentally operate the air supply/shut-off switch, causing the tape cutter or
pneumatic components to be activated and possibly injuring the service engineer.
To prevent this, lock-out padlock is available for the operator to padlock the air supply/shut-off
switch before starting the service work.
Turn the air supply/shut-off switch to shut off the main air supply
Step 1 Turn the air supply/shut-off switch clockwise to shut off the main air supply.
Step 2 Padlock the air supply/shut-off switch using the dedicated holes (see “Note” below).
Step 3 Just to make sure, disconnect the air supply hose.
Note:
Depending on the model, layout of the padlock (keyhole location) and the air supply/shut-off switch vary.
Verify their layout before using the padlock.
