General Gun Care
•
Always keep the spray gun clean. Dirt, grit and metal dust in the
mechanism will cause quick wear. Before lubrication or overhaul,
wipe the gun thoroughly to remove all loose dirt.
•
Use a clean work bench.
•
When disassembling, replacing and assembling any parts that
contain o-rings, inspect all o-rings. Check for wear, cuts, nicks and
flat areas. Replace any o-ring that is not in very good condition.
Apply a light coating of Krytox® lubricant to all o-rings before
assembling. The lubricant is required to ensure a proper seal and
makes assembly easier.
•
Use only Krytox® on all o-rings. Do not use Sulzer Metco Valve-
lube or Ringlube.
•
Keep the teeth on the drive rolls clean by brushing with a wire
brush. Blow out chips or shavings from the cavity in the central
housing using compressed air.
•
Use a small amount of Krytox® on the threads of the air cap body,
nozzle nut, rear countershaft bearing retainer and control ring.

Siphon Plug
The siphon plug should be cleaned occasionally. Wipe out the grooves
and clean out the holes with the proper size wires from the cleaning
wire kit.
Do not wash the o-rings with cleaning solvent. Inspect them for dam-
age and replace them if necessary. Do not stretch new o-rings more
than necessary. Lubricate all o-rings with Krytox® before reassem-
bling the siphon plug. Wipe any excess Krytox® off the plug.
6.3
Nozzles
Whenever a nozzle is put on the gun, the bore of the siphon plug
should be wiped clean and a fresh film of Krytox® put on the nozzle o-
rings. The nozzle nut must be tight on the siphon plug. Firm tightening
by hand is sufficient. Overtightening the nozzle nut can cause dam-
age.
The nozzle should be kept clean. To clean the nozzle, remove the noz-
zle o-rings and wash the nozzle in cleaning solvent. Clean jet holes
with the proper size wire from the cleaning wire kit. From the back end,
push the cleaning wire carefully into each jet hole. From the back end,
blow out the holes with compressed air. Do not wash the o-rings with
cleaning solvent. Inspect them for damage and replace them if neces-
sary. Do not stretch new o-rings more than necessary. Lubricate o-
