7. MAINTENANCE

■ 

Maintenance of the electromagnetic valve and pump head

●

 Remove the cover

When performing maintenance on either the electromagnetic valve or the pump head, remove the 

screws holding the cover and take the cover off.

●

 Electromagnetic valve maintenance

1. Remove the screws holding the electromagnetic valve in place.

Performing proper and periodical maintenance extends the product life. Efficient soldering depends upon

the temperature, the quality and quantity of the solder and flux. Apply the following service procedure as

dictated by the conditions of the usage.

WARNING

Since the handpiece tip/nozzle can reach a very high temperature, please work carefully. Except the case especially indicated,
always turn the power switch OFF and disconnect the power plug before performing any maintenance procedure.

3. After use

4. When the unit is not

being used and the

auto power shutoff

is not active.

High temperatures shorten tip life and may cause thermal shock to components. 

Always use the lowest possible temperature. The excellent thermal recovery 

characteristics of the HAKKO FM-206 ensure effective soldering at low 

temperatures.

Always clean the tip/nozzle before use to remove any residual solder or flux 

adhering to it. Use the tip cleaner or cleaning sponge. Contaminants on the tip 

have many deleterious effects, including reduced heat conductivity, which 

contribute to poor performance.

Always clean the tip/nozzle and coat it with fresh solder after use. This guards 

against oxidation.

This procedure, if followed daily, will materially add to tip life.

a. Set the temperature to 250

℃

 (482

℉

).

b. When the temperature stabilizes, clean the tip and check the condition of the 

tip. If the tip is badly worn or deformed, replace it.

c. If the solder plated part of the tip is covered with black oxide, apply fresh 

solder, containing flux, and clean the tip again. Repeat until all the oxide is 

removed, then coat the tip with fresh solder.

d. Turn the power OFF and remove the tip, using the heat resistant pad. Set the 

tip aside to cool.

e. Remaining oxides, such as the yellow discoloration on the tip shaft, are not 

harmful but can be removed with isopropyl alcohol.

Never allow the unit to idle at a high temperature for extended periods. This will 

allow the tip to become oxidized. Turn the power switch OFF. If it is to be out of 

service for several hours, it is advisable to pull the power plug as well.
