1.2 Using safety gear
Always wear safety gear when operating or performing maintenance for the equipment.
Helmet: Use during the maintenance work as required
Safety boots & work cap: Use during the maintenance work
Safety glasses or goggles: Use when exposed to light harmful to eyes and when applying
lubricant, etc.…
Respiratory gear: Use when handling organic solvents
Safety gloves: Use when removing parts and applying lubricant
(Basically use during the maintenance work.)
Warning: ~ Precautions when applying lubricant (grease) ~
Inflammation may occur if grease or lubricant gets in your eyes. Before handling the grease or
lubricant, wear safety goggles to ensure it will not come in contact with your eyes.
Inflammation may occur if the grease or lubricant comes into contact with skin. Be sure to wear
protective gloves to prevent the grease or lubricant from coming in contact with skin.
Do not take orally or eat the grease or lubricant. Eating will cause diarrhea and vomiting.
1.3 Safety panels below the tape cutter area (common to all the applicable models)
The front and rear safety panels below the tape cutter area are to be removed for servicing the
tape cutter, machine controllers and other parts. To ensure safety of the operator and bystanders,
the machine is equipped with safety interlock which disables operation of the machine when the
safety panels are removed. The safety panel is heavy and bulky, so be careful when handling it to
avoid injuries and damage to itself.

Note:
If the tape cutter fails or a related problem occurs, please do not tamper with the suspected parts
but contact YAMAHA to seek assistance. Unauthorized service or repair won’t be covered by
warranty.

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.
