GroundingGrounding
Grounding
Proper grounding is an essential part of maintaining
a safe system.
To reduce the risk of static sparking, ground the
pump. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment. Be sure to ground all of this equipment:
Pump: Use a ground wire and clamp as shown in
Fig. 1.
Air compressors: Follow manufacturer’s
recommendations.
Object being sprayed: Follow your local code.
All solvent pails used when 󰘱ushing or relieving
pressure:
Always hold a metal part of the gun 󰘰rmly
to the side of a grounded metal pail, then trigger the
spray gun.
To maintain grounding continuity when 󰘱ushing or
relieving pressure:
Always hold a metal part of the
spray gun 󰘰rmly to the side of a grounded metal pail,
then trigger the spray gun.

Pressure ReliefRelief Relief ProcedureProcedure Procedure
INJECTIONINJECTION
INJECTION HAZARDHAZARD HAZARD
The system pressure must be manually relieved
to prevent the system from starting or spraying
accidentally. Fluid under high pressure can be
injected through the skin and cause serious injury.
To reduce the risk of an injury from injection,
splashing 󰘱uid, or moving parts, follow the Pressure
Relief Procedure whenever you:
• are instructed to relieve the pressure,
• stop spraying/dispensing,
• check or service any of the system equipment,
• or install or clean the spray tips or nozzles.
1. Shut off the air to the pump.
2. Close the bleed-type master air valve (required
in your system).
3. Hold a metal part of the gun to the side of a
grounded metal pail and trigger the gun to relieve
pressure.
4. Open the 󰘱uid drain valve (required in your
system), having a container ready to catch the
drainage.
5. Leave the drain valve open until you are ready to
spray/dispense again.
If you suspect that the spray tip/nozzle or hose is
clogged or that 󰘱uid pressure is not fully relieved after
following the steps above
, veryvery
very slowlyslowly slowly loosen the tip
guard retaining nut or hose end coupling and relieve
pressure gradually. Clear the tip or hose obstruction.

NOTE: Repair Kit 214584 is available. For best
results, use all the new parts in the kit, even if the
old parts look good. Parts included in the kit are

Air PistonPiston Piston andand and LowerLower Lower SpringSpring Spring ServiceService Service
To reduce the risk of injury from trapped air
pressure when servicing the air motor, always
remove air cap (7) from air cylinder (8) before
removing air cylinder from base (22).
1. Unscrew the cylinder cap (7) from the cylinder
(8). To remove the spring (5), pry gently under
the coils in the direction of the helix.
2. Unscrew the cylinder (8) from the base (22) and
lift the cylinder off the air piston (11). Using a
pliers (B) on the air exhaust plate (16) and a
wrench (C) on the piston shaft (23), unscrew the
piston from the shaft. See Fig. 2.
NOTICENOTICE
NOTICE
Ketone fumes may damage the piston o-rings.
When pumping ketones (such as acetone,
MEK, etc.), use Conversion Kit 221038. This
kit replaces the standard 󰘱uoroelastomer
o-rings with EPDM o-rings which are resistant
to ketones.
3. Disassemble the piston and wash all parts in
compatible solvent. Refer to the parts list on
page 9. Blow parts dry and inspect for wear
or damage. If any of the valve plate spacers
(13) are damaged, replace all three to maintain
proper clearance between the valve plates and
the seats.
4. Remove and inspect the lower spring (20).
Replace if necessary, and reinstall.
5. A decrease in performance accompanied by
a slower than normal cycle rate is commonly
caused by icing. It is recommended that the
pump is shut down, and the ice is allowed to
thaw.
6. Reassemble the air piston (11), using new parts
as needed. Apply a good grade of thread sealant
to the threads of the screws (12). and torque
evenly to 1.1–1.6 N•m (10–14 in-lb). With the
washer (4) in place, apply thread sealant to the
threads of the piston. Carefully screw the piston
(11) onto the shaft (23) by hand so it is securely
fastened. Do not use pliers on the air exhaust
plate while tightening. When installed, there
should be 0.8 mm (0.032 in.) minimum clearance
between the washer (4) and the piston shaft
shoulder. See Fig. 2.

2. Unscrew the cylinder (8) from the base (22) and
lift the cylinder off the air piston (11). Disconnect
the piston shaft (23) from the pump connecting
rod and pull the shaft up out of the air motor
base. Remove and inspect the packing (9†),
being careful not to mar the inner lip. See Fig. 2.

not compatible with the standard nitrile rubber
packing.
3. Replace the packing and reassemble the air
