SAFETY INSTRUCTIONS
■To avoid injury, do not attempt to assemble
while the soldering iron is hot.
■The cutting plate is sharp. Be careful not to cut
your fingers.
■When resin core solder that has been cut is
not used, the properties of the resin (flux) may
deteriorate with time.
■Once the solder has been cut and is inside the
guide pipe, the heat from the soldering iron may
accelerate the deterioration of the resin (flux).
Use solder that is inside the guide pipe as soon
as possible.
■Do not damage the guide pipe by bending or
twisting it.
SPECIFICATIONS
■Do not allow the tube to be bent at a severe
angle. Otherwise, it will become clogged with
solder.
■Keep the cutting blade, driving pulley, and
following pulley clean of solder and flux using
a brush or other suitable cleaning device.
■The switch input is no-voltage input. Do not
apply voltage to the switch jack.
■Periodically remove the nozzle and clean off
any accumulated flux.
■Do not damage the return length adjustment
knob by turning it with excessive force.
