Wear protective goggles and gloves and
parts is toxic and flammable.
use only in a well ventilated
area. Avoid contact with skin, eyes and clothes and don-t breathe
vapors. Do not use near open flame or excessive heat and don’t smoke
when using it. Failure to do so could cause serious injury. If you be-
come dizzy while using cleaning solvent, get fresh air and medical
attention immediately. If contact with skin or clothes is made, flush
with large amounts of water. If contact with eyes is made, wash eyes
with water and get medical aid immediately.
Using a stone, remove sharp edges from end
of cleaning wire. A small flat on one side
of cleaning wire will make it easier to cut
carbon from orifice. Put cleaning wire in
spray orifice and turn wire until it is
free. Wash nozzle tip using cleaning sol-
vent P-D-680 and inspect tip using a
magnifying glass. Replace nozzle tip and
valve as an assembly if orifice in tip
shows damage at edges. Damage to orifice
will change spray pattern.
Compressed air used for cleaning purposes will not exceed 30 psi. Use
only with effective chip guarding and personal protective equipment
(goggles/shield, gloves, etc). Failure to do so could cause serious
injury to eyes and possible blindness. If you hurt your eyes or if a
foreign object is blown into your eyes, seek medical attention
immediately.
Using compressed air, clean all channels of nozzle tip. Apply compressed air
at both ends of nozzle tip to remove all carbon deposits.
Carefully clean inside diameter of nozzle tip to remove all dirt, varnish, and
other deposits. If necessary, use paint thinner to remove varnish deposits.
Use compressed air to remove foreign matter.
Using a brass wire brush, remove deposits from seat location of nozzle valve.
If necessary, use paint thinner and a cleaning pad made of felt to remove
varnish. Check valve for pitting or damage which could cause leakage.
Install nozzle valve in nozzle tip and ensure that it slides freely in nozzle
tip.
Use spring gage to check adjusting spring compression under load. Replace
adjusting spring if pressure required to compress spring to 1.00 inch is not
87.5 pounds.
