Reassemble the Chamber and place the Felt Filter against the spring loaded
plunger of the breach. Be careful to ensure the filter is centered on the breach
plunger as it is easy for the fibers of the felt to break the seal that the Silicone Seal
must make with the Chamber Housing. Once properly positioned, push back on
the chamber and tip it into the front housing. Finally push the Breach forward
until it clicks and locks into place. The ZD-985 is now once again ready to return to
service. Figure 4 identifies the Plunger and Silicone Seal.
Be sure to keep adequate consumables and spare parts on hand to eliminate
down time and to protect the function of the Desoldering Station.
Routine Tip Cleaning
It is important to routinely clear the residual oxidized solder and scale from the
Desoldering tip. This is easily accomplished by pushing the, appropriate, cleaning
rod (A, B, or C) through the tip and into the solder capture chamber, at the end of
each use, before turning the machine off. Use the vacuum trigger to apply
vacuum during and after the cleaning rod is push through and removed. This
routine procedure should eliminate the need to fight with a clogged tip. Caution
as cleaning rods become very hot when inserted into the tip.
Cleaning a Clogged Tip
Note: This is the only maintenance procedure where it is necessary to have the
unit at high temperature. Extra caution should be exercised to prevent burns and
injury. If proper techniques are followed a clogged tip should be a rare
occurrence. Select the correct cleaning rod from your accessory kit. SET the target
temperature to the maximum 480 degrees C. Try once again to clear the clog with
the vacuum alone. If the clog is still present, activate the vacuum trigger again and
push the cleaning rod (A, B, or C) gently into the tip orifice. Alternately push and
remove the cleaning rod to allow the vacuum to clear any debris to the Collection
Chamber. It is important to approach the surface of the tips surfaces, internally
and externally, with care as scratches and abrasions will shorten the life of the tip.
Do not Drill or use cutters to clean a tip. If your tip is scratched or corroded,
contact Memotronics for replacement parts.
