MAINTENANCE
With proper care, this unit will give long reliable service. To maintain this
performance it should be flushed out with solvent immediately following
each spray period.
CAUTION
Always disconnect pump power source and reĆ
lease all pressure before disassembly or removal of any part.
FOR CLEANING: Use solvent with highest possible flash point,
that is compatible to material being used.
1. ShutĆoff air pressure to pump and relieve liquid pressure in system
through manual relief valve at outlet filter on those models
equipped, or trigger gun making sure pressure is relieved. Never
attempt to force paint backward from gun through hose to pump
and paint container.
2. Place gun safety lock in closed position and remove spray tip from
gun. Place tip in small container of solvent for soaking and final
cleaning. Use soft bristle brush to remove any paint collection on
tip. If tip orifice is clogged, remove obstruction by using air blow gun
applied to outlet of orifice at front of tip and blowing back through
rear of tip, if obstruction will not blow out, use cleaning wire, toothĆ
pick or brush bristle to dislodge.
NEVER ATTEMPT TO CLEAN
TIP WHILEIT IS ATTACHED TO SPRAY GUN.
3. Remove gun from hose and clean exterior with suitable solvent and
brush. Allow gun to soak in solvent for a short time if necessary to
soften accumulation. After cleaning, wipe exterior of gun with dry
cloth. (NOTE: Interior of gun has not yet been cleaned).
4. Remove pump from paint container and place pump inlet into conĆ
tainer of suitable clean solvent.
5. Direct open end of hose into paint container and start pump by apĆ
plying only sufficient air pressure to cycle pump slowly and to force
paint from pump and hose into grounded paint container. When solĆ
vent begins to flow from hose, switch hose to grounded solvent conĆ
tainer, increase air pressure to pump allowing solvent to circulate
through pump, hose and back to container for approximately one
minute or until examination indicates hose and system are clean.
6. Whenever 60530 inline swivel filter is being used, remove from
hose and gun, disassemble and clean.
7. ShutĆoff air pressure to pump and assemble gun to end of hose.
8. Direct end gun (without tip) into top of grounded (bonding recomĆ
mended) solvent container and release safety lock on gun so trigĆ
ger can be retracted.
9. Start pump with gun trigger retracted, increase air pressure until
sufficient pressure is obtained to cause pump to cycle approximateĆ
ly 25 cycles per minute. Purge gun approximately one minute while
intermittently operating trigger. Adjust packing gland if necessary to
prevent leakage.
10. ShutĆoff air pressure to pump and pull gun trigger to relieve presĆ
sure in system while gun is still directed into grounded solvent conĆ
tainer.
11. Place safety lock on gun in closed position and reassemble cleaned
spray tip to gun, wipe all exterior surfaces clean.
12. Disconnect pump from power source.
SERVICE
If material leakage occurs around the (12) retaining screw, the (10)
packing and the (11) flat packing have perhaps become worn. Tighten
the (12) retaining screw and if this doesn't stop the leakage replace the
packing.
If material leakage occurs at the spray tip of the gun, check for dirt or
foreign matter which may prevent the (7) ball and stem assembly from
seating properly.
DISASSEMBLY
1. Disconnect air line from pump and relieve material line pressure by
pulling (22) trigger.
2. Disconnect material line from gun.
3. Unscrew the (1) cap and guard assembly and remove the (2) washĆ
er and spray tip.
4. Loosen the (13) collet nut.
5. Loosen the (19) set screw. Disconnect and remove the (21) inlet
tube brazing assembly by loosening the tube nut and rotating the
tube assembly 90
_
to either side of the (20) handle.
6. Unscrew the (9) spray gun body and adapter assembly from the
(20) handle.
7. Remove the (3) screw, (8) washer and (12) retaining screw from (9)
spray gun body and adapter assembly.
8. Remove the (7) ball and stem assembly and the (10) packing and
(11) flat packing from the (9) spray gun body and adapter assembly.
For normal cleaning or service, parts (14), (15), (16), (17), (18), (22),
(23), (24), (25), (26), (27) and (28) need not be removed.
REASSEMBLY
1. Insert the (7) ball and stem assembly into the (9) spray gun body
and adapter assembly.
2. Carefully slip the two (10) packings and two (11) flat packings in the
order shown in the diagram over the wire of the (7) ball and stem
assembly.
3. Slide the (12) retaining screw onto the (7) ball and stem assembly
and push the packings into the (9) spray gun body and adapter asĆ
sembly. Tighten (12) retaining screw hand tight.
4. Install the (8) washer on the (3) screw and screw the assembly into
(9) spray gun body and adapter assembly hand tight. Then back off
screw 3/4 turn.
5. Push the (7) ball and stem assembly forward until it seats on the ball
seat of the (3) screw and tighten (12) retaining screw.
6. Screw the (9) spray gun body and adapter assembly into the (20)
handle. Be sure the wire of the (7) ball and stem assembly enters
the hole in the (13) collet nut. Back off the (9) spray gun body and
adapter assembly until material inlet faces down. Tighten (19) set
screw.
7. Being sure the ball is still seated in the ball seat, retighten the (13)
collet nut.
8. Tighten the (3) screw.
9. Replace the (21) inlet tube brazing assembly into the (20) handle
and (9) spray gun body and adapter assembly.
10. Check safety operation by rotating the (25) knob to the safe position
and pull the (22) trigger. If movement of the (7) ball and stem asĆ
sembly is noted, adjust the gun as follows. With the safety off and
the ball seated on the ball seat, hold the trigger and loosen the (13)
collet nut. Pull the trigger back slightly and retighten the (13) collet
nut. Recheck safety operation and readjust if necessary.
11. Insert the spray tip and (2) washer in the (1) cap and guard assemĆ
bly and screw cap on (9) spray gun body and adapter assembly.
