Safety panel removed
When the safety panel is removed, the safety limit switch shuts down power to the tape cutter,
disabling the tape cutter operation. (The default cutter blade position is set to “Close”.)
Warning:
Before removing the safety panel(s), be sure to release the air in the tape cutter by operating the air
supply/shut off switch. If you reverse the steps, the cutter blade might move due to the residual
pressure inside the air hose or the unit and may cause serious injuries.

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.
