4.8 Keeping hands away from moving parts
During use of this machine, the customer’s equipment and operating conditions might allow the operator’s
hands to come into contact with moving parts. Use the following safety measure options to avoid possible
danger where openings or gaps are found on the machine.
►
Dummy feeder
Use dummy feeders as safety measures to fill a gap between tape feeders. Install dummy feeders on the
feeder plate the same way as normal feeders in order to prevent hands from entering.

CAUTION
To install or remove a dummy feeder, be sure to first press emergency stop button and then open cover. The
machine has structure that does not allow installing or removing dummy feeder when machine is in operation.
However, inserting dummy feeder inside cover during operation may cause serious accidents, so be careful
not to attempt it.

One-stop cover (for machines with feeder exchange carriage)
If not using a feeder exchange carriage in the machine that is to be used with feeder exchange
carriages, install a one-stop cover in the position where a feeder exchange carriage is to be installed.

NOTE
One-stop covers cannot be installed or removed during operation. The machine must be in a stopped state because
the section where a feeder exchange carriage is to be installed will move up and down for the installation or removal
of the feeder exchange carriage.

Muzzle plate
Use these plates as a safety measure for the board conveyor entrance and exit openings. Each plate is
movable, so adjust the mounting position to match the boards to be produced.

CAUTION
When installing a unit such as a loader or an unloader on the upstream or the downstream side of the machine, set the
muzzle plates to the opening of the board conveyor entrance or the board conveyor exit to make the opening small.

4.9 Handling solvents (including solder, adhesive, and flux)
Cleaning organic solvents, such as isopropyl alcohol (IPA) and ethanol are used for the maintenance of this
machine (including optional units). Additionally, the solder paste printers, dispensers, and some hybrid
placers and flip chip bonders use solder, flux, or bond, etc. during normal production. As many of these
materials include organic solvents, great care should be taken when handling them.
►
Cautions on handling solvents
1. Harmful to human body
Organic solvents constantly vaporize and contaminate the surrounding atmosphere. Inhaling or
coming in contact with organic solvent vapor may cause serious damage to human health.
2. Flammability
Organic solvents are highly flammable substances and can easily catch fire if handled improperly.
3. Adverse effects on machines
Some kind of solvent may deteriorate parts used in the machine, electric cable sheathes, and other
resin parts.
►
To prevent accidents caused by solvents
1. Be careful not to inhale toxic vapors of solvents for extended periods.
2. Do not use solvents near fire or flame. Keep solvents away from flame or fire.
3. Use only the specified solvent in the correct manner. Do not reuse any solvent repeatedly, and do not
mix with other solvents or chemicals.
4. Check the contents of the safety data sheet (SDS), thoroughly notify work personnel of toxicities of
included chemical materials and measures to be taken in case of an accident, and take necessary
countermeasures.
5. Use appropriate safety gear (safety goggles, protective gloves, and respiratory protective devices)
corresponding to the solvent or material types.
6. See the safety data sheet for how to dispose the solvents and the cloths used for wiping off the
solvents.
c
CAUTION
If no safety data sheets are supplied with solvents or materials you have purchased, be sure to acquire the safety data
sheets from the suppliers.
4.10 Handling the laser
This machine (including optional units) has portions using the laser, such as a sensor and barcode reader.
c
CAUTION
The laser to be used in this machine is class 2 (visible light and low output) at a maximum.
►
Knowledge and information about laser
1. Harmful to human body
Never look at the laser directly even when it is weak. In particular, if the laser is irradiated to an eye
for a long time, this may cause serious injury.
2. Reflection of laser
The laser is reflected by a glass or metal surface. Pay special attention to the reflected laser light
during maintenance work.
►
To prevent accidents caused by laser
1. Do not align your eye with the laser height so that you do not look at the laser directly.
2. Wear safety goggles during work, when necessary.
3. Shield the laser during work, when necessary.
