rings with Krytox® before reinstalling the nozzle. Wipe any excess
Krytox® off the nozzle.

The bushing inside the nozzle is intended to fit the wire precisely. This
prevents gas leakage and backfire. This bushing is a very durable
alloy that resists fusing with wire metals (i.e., loading). The bushing will
wear over time, requiring that the nozzle be replaced.

Gas Head Valve

Proper lubrication of the gas head valve is essential for operation of
the safety handle and for a perfect seal of all gases. The valve core
must always move freely and easily to all positions. If the gas head
valve becomes stiff, fails to close within 1 second of releasing the
safety handle or fails to seal completely, disassemble and clean the
parts of the gas head assembly. Replace all o-rings and apply Kry-
tox®.

Always remove the hose block and valve plungers before removing
the valve core. One of the hose block mounting screws extends into a
channel in the valve core to prevent the valve core from being
removed while the hose block and valve plungers are installed.

When replacing the o-rings on the valve core, install the o-rings on the
valve core dry. Then, apply a generous amount of Krytox® to the
entire surface of the valve core. After servicing the valve core, purge
the spray gun thoroughly to clear any lubricant from the valve pas-
sages.

The three valve plungers in the hose block have radiused faces to
mate with the curvature of the valve core. The o-rings between the
plungers and valve core are special. They must not be replaced with
non-Sulzer Metco parts. Do not clean these o-rings with solvent. Over
time, these o-rings will become curved and flat and should be
replaced.

6.5

Countershaft / Bearing Lubrication

To lubricate a dry gun, use no more than 1 fluid oz (30 ml) of Sulzer
Metco Gearlube to fill the gear case. To do this, remove the oil filler
plug from the back of the central housing. Pour in the correct amount
of Gearlube. With the gun upright and level, the lubricant should be
visible at the bottom of the filler plug threads. Check level again after
waiting a short time then install the filler plug and o-ring.

CAUTION

When servicing the gas
head valve, always fol-
low instructions for dis-
assembly under “Gas
Head Assembly” on
page 51 and assembly
under “Gas Head
Assembly” on page 65.
