Safety instructions

1.8 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.

Prevention of hand entry

CAUTION

To install or remove a dummy feeder, be sure to ﬁrst press the emergency stop button and then open the cover. The

machine has a structure that does not allow installing or removing a dummy feeder when the machine is in operation.

However, inserting a dummy feeder inside the cover during operation may cause serious accidents, so be careful not

to attempt it.

One-stop cover (for machines designed for use with feeder exchange carriage, excluding YSM40/YSM40R)

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.

One-stop cover

91204-L0-10

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.

Safety instructions

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.

Safety instructions

1.9 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. Since many of these materials

include organic solvents, great care should be taken when handling them.

Cautions on handling solvents

1. Hazards to human health

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 (MSDS/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 (MSDS/SDS) for how to dispose the solvents and the cloths used for wiping off the solvents.

CAUTION

If no safety data sheets (MSDS/SDS) are supplied with solvents or materials you have purchased, be sure to acquire

the safety data sheets from the suppliers.
