15. MAINTENANCE (Desoldering Tool)
WARNING
Since the desoldering tool can reach a very high temperature, please work carefully.
Except when cleaning the nozzle and heating element, ALWAYS turn the power switch
OFF and disconnect the power plug before performing any maintenance procedure.
Properly maintained, the HAKKO FR-702 desoldering tool should provide years of good
service. Efficient desoldering depends upon the temperature, nozzle selection, and
proper routine maintenance. Perform the following service procedures as dictated by
the conditions of the station's usage.
During suction, the gauge indicating suction force
is shown at the bottom of the screen.
If "CHK" appears on the display, check the nozzle
and heater for restrictions.
If the nozzle or heater are clogged, clean or replace
them.
