Maintenance; Adjusting The Packing Nut; Replacing The Needle Packing And Air Valve Seals - Titan Maxum Elite Notice D'utilisation

Maintenance

Perform the following maintenance procedures to keep your HVLP
spray gun working properly. New parts can be obtained by ordering
the HVLP Gun Repair Kit, part number 0279911.

Adjusting the Packing Nut

If material leaks from around or through the packing nut, readjust the
packing nut.
1. Disconnect the air hose from the air inlet and remove the cup
assembly.
2. Pull the trigger all the way back and hold.
3. Tighten the packing nut using a 3/8 inch wrench until the
needle remains retracted inside the nozzle when you release
the trigger.
4. Loosen the packing nut slowly
until the needle moves freely
back into position in the nozzle.
Once you have adjusted the nut,
reconnect the air hose and the cup
assembly. Squeeze the trigger to see if
the leaking has stopped. If it has not,
make sure the packing nut is as tight as
possible, while allowing the needle to
move freely. If adjusting the packing
nut does not stop the leak, replace the
packing.
Replacing the Needle Packing
and Air Valve Seals
NOTE: Remove the needle packing only when replacing
with a new needle packing. Do not remove the
needle packing for cleaning.

replaced separately. If you are replacing only one of
them, use the appropriate steps from the following
procedures.
