PRECAUTIONS FOR USING LEAD-FREE SOLDER

1. Employing lead-free solder

Example:

Indicates lead-free solder of tin, silver and copper.

Lead-free wire solder for servicing

Ref No. Description

Parts No.

"MAIN, POWER, AMPLIFIER PWB" of this model employs lead-free solder. The LF symbol indicates lead-free

solder, and is attached on the PWB and service manuals. The alphabetical character following LF shows the type

of lead-free solder.

Using lead-free wire solder

When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional

lead wire solder may cause damage or accident due to cracks.

As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend

you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering

bit, contact our service station or service branch in your area.

Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead

solder by 40°C,and as it has poor solder wet ability, you may be apt to keep the soldering bit in contact with the

PWB for extended period of time. However, since the land may be peeled of for the maximum heat-resistance

temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady

soldering condition.

Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn

on and off the power of the bit as required. If a different type of solder stays on the tip of the soldering bit, it is

alloyed with lead-free solder. Clean the bit after every use of it.

When the tip of the soldering bit is blackened during use, file it with steel wool or fine sand paper.

Be careful when replacing parts with polarity indication on the PWB silk.

CHAPTER 3. MECHANISM BLOCKS

[1] Disassembly

Caution On Disassembly

Follow the below-mentioned notes when disassembling the unit and reassembling it, to keep it safe and ensure

excellent performance:

1. Be sure to remove the power supply plug from the wall outlet before starting to disassemble the unit.

2. Take off nylon bands or wire holders where they need to be removed when disassembling the unit. After servicing

the unit, be sure to rearrange the leads where they were before disassembling.

3. Check that all speaker cushions (refer items 212, 214, 215 and 216 on pages 6 and 7 of Parts Guide) are properly

sealed otherwise vibration noise will be very distinct at low frequency sound.

Replace the cushions if they are found damaged during servicing.
