Prepare the Gun for Service
NOTE:
Check all the possible remedies in
Troubleshoot-
ing, pages 24 to 26, before disassembling the gun.
If the plastic parts of the gun must be held in a vise,
use padded vise jaws to avoid damaging parts.
FIRE, EXPLOSION, AND
ELECTRIC SHOCK HAZARD
To reduce the risk of a fire, explosion, or
electric shock:
Be sure the turbine air (TA) is off
before flushing the gun or any part of
the system.
Clean all the parts with a compatible
solvent that is suitable for electro-
static equipment.
Do not service this equipment unless you are
trained and qualified.
Do not touch the gun nozzle or come within 4
inches (101.6 mm) of the nozzle during gun op-
eration.
WARNING
CAUTION
Methylene chloride is not recommended as a flush-
ing or cleaning solvent with this gun as it will dam-
age nylon components.
PRESSURIZED EQUIPMENT
To reduce the risk of a serious injury,
follow the
Pressure Relief Procedure
on page 17 when you stop spraying, be-
fore servicing the gun, and whenever you are
instructed to relieve the pressure.
WARNING
1. Flush the gun with a compatible solvent.
2. Relieve the system pressure.
NOTE: The service area must be clean. Remove the
gun from the worksite as instructed in the following
steps.
3. Loosen the bottom gun screw (21) until the gun (B)
sits loosely in the mounting bracket slot (A). Refer
to Fig. 19.
CAUTION
The piston return spring (105) is compressed
between the manifold (101) and gun body when
they are assembled. To avoid sudden movement of
the gun, loosen the bottom gun screw (21) before
loosening the three manifold bolts (106). This
allows the gun to move forward gradually as the
manifold bolts are loosened. Hold the gun firmly in
hand while loosening the manifold bolts.
4. Holding the gun (B) firmly in hand, loosen the three
bolts (106) from the back of the manifold (101)
with the ball end wrench (77–
not shown).
5. Remove the gun (B) from the manifold (101), and
take it to the service area.
