Always have the tip guard in place while spraying.
Even after you shut off the electric motor, there is high
pressure in the pump, hose and gun, until you release it.
A/ways release pressure when you are done spraying and
before servicing, cleaning, or removal of any parts. To release
pressure, shut off the unit, engage trigger safety and open
drain valve. Have a container ready to catch draining material.
DO NOT try to”blow back” paint; this is NOT an air spray unit.
NEVER leave a pressurized unit unattended.
When spray gun is not actually spraying, always set gun
safety latch in closed, or “SAFE” position, making the trigger
inoperative. DO NOT REMOVE OR MODIFY any part of
spray gun. Check diffuser operation by using the lowest
possible spray pressure without a spray tip. Trigger gun into a
waste container - fluid emitted should be diffused into an
irregular stream.
KEEP CLEAR OF MOVING PARTS ., ; , _j ;: : ,: ‘:: : ’

cutting; also do not exposure to temperatures above 180’ F
(82” C) or below -40” F I-40” C). Do not use hose to pull unit. Tighten all fluid connections securely before each use.
PREVENT STATIC SPARKING,., ,’ I, ‘-,i :,,. ,,, :.’ .,, I’:; :‘ i : i ~ ;
The high velocity flow of material through equlprnent may
develop static electricity. Be sure that the equipment being
used, and the object being sprayed, are properly grounded to
prevent static discharge and sparks which could cause fire or
explosion.
Use only conductive or grounded fluid hoses for airless
applications. Be sure that gun is grounded through hose
connections.
Once each week, check electrical resistance of hose (when
using multiple hose assemblies, check overall resistancel.
Overall (end to end) resistance of unpressurized hose must not
exceed 29 megohms (max.) for any coup!ed length or com-
bination of hose lengths. If hose exceeds these limits, replace
it immediately.
Never exceed 500 ft (150 m) overall combined hose length
This unit has a 3-prong grounding plug to protecr you frorn
electric shock. Be sure to plug the unit into a properly
grounded outlet that will accept the 3-prong plug. Do not
remove the third prong.
The green ground wire of electric cord is connected to the unit
chassis and motor frame and the other two wires are
connected to the switch motor for grounding continuity.
Plug into an outlet at least 20 ft (6 m) from the area where you
are spraying. If you use an extension cord, it rnust have 3 wires
of at least 12 gauge (2.5 mm2) and should not be over 100 ft
(30.3 ml long.
Use the lowest possible pressure when flushing equipment,
and maintain firm metal to metal contact between gun and a
grounded metal waste container. This reduces the chance of
static sparking.
Follow the coating and solvent manufacturer’s safety pre-
cautions and warnings.
IMPORTANT
United States Government safety standards hd’:e been adopted under the Occupational Safety and Health Act. These standards --
particularly the General Standards, Part 1910, aird the i3onstruction Standards. Part 1926 ~ should be consulted in connection with
your use of airless spray equipment.

Fig 1
Check Hydraulic Fluid Et Put TSL In Wet-Cup
Before initially plugging unit into service outlet, take the
shield covering the top of the unit off by releasing the 2
spring clips and pulling shield up.
Take the expander plug out of sump fill hole, put your
finger inside strainer-dipstick flange and pull it out of
hole. See Fig 1. Use a clean, lint-free rag to wipe
dipstick dry, then put strainer back into hole and
remove it to check fluid level. Level should be between
ADD and FULL.
Hydraulic fluid was put into sump at the factory. If fluid
level is on the ADD mark or below, first put strainer
back into sump, then add approved hydraulic fluid (see
ACCESSORIES; page 11) through hole as necessary to
bring level to the FULL mark. l-3/4 (0.8 liter) will raise
the level from ADD to FULL.
Pour Grace Throat Seal Liquid (TSL), supplied, into
wet-cup until wet-cup is about 113 full. See Fig 1.
Connect Gun
Remove cap plug from nipple on outlet manifold and
connect spring guard end of 25 ft (7.6 m) fluid hose to
manifold. Then connect the whip end hose to fluid hose
and spray gun’s inlet connection. Tighten all con-
nections securely. Do not use thread sealer. Replace
shield on unit.
Plug Cord Into Grounded Outlet
This unit requires 115 volt, 60 HzAC, 15 amp electric
service.
A licensed electrician can rewire the unit for 230 volt
service, if necessary. See the wiring diagram on page 7.
Check to be sure ON-OFF switch is in the OFF position,
then plug cord into service outlet. If you have to use an
extension cord to reach a service outlet, be sure it is a
3-wire, 12 gauge (min.) cord with safety grounding plug
and socket. Do not use more than 100 ft (30 m) of
extension cord.
Flush Oil Out Of Paint Pump
You will have to flush oil used for testing and protection
out of the paint pump before starting to spray. To flush
proceed as follows:
Pour about a gallon of clean, compatible solvent into an
empty 5-gallon metal pail - take precautions to prevent
static sparking when pouring solvent. Put suction tube
into pail. See Fig 2.
Turn the pressure control knob counterclockwise until it
stops. Pull the switch up to the ON position. Hold the
gun, with spray tip removed, firmly against the bare
metal of waste container and squeeze the trigger. At the
same time, slowly turn the pressure control knob
clockwise to increase pressure until the paint pump runs
slowly. Hold the trigger back until clean solvent is
coming from the gun, then release it. The pump will
stall against pressure when you release the trigger.
Always use the lowest possible pressure when flushing.
Check all the paint line connections for leaks. Tighten if
necessary.
Remove the suction tube from the solvent pail. Trigger
the gun to let the pump force the solvent out of the
hose, then push the switch down to the OFF position
and open drain valve to relieve pressure (provide a can
to catch drainage). Engage the trigger safety.

off gun, and p!~: fr(>lIt end of gun and tip in solvent.
Whenever possible, park the a:;it In the shade or a
relatively cool area to reduce the possibility of over-
heating.
When through spraying always stop pump at the
bottom ot its stroke to prevent materiai from drying on
displacemen: rud and possibly darnaging the throat
packinijs Check packing-nut wet-cup tightness
periodically and tighten with l/4 in. diameter rod if
necessary. See Fig 3.

If y(JCi ri+e vv:jter to flush, pump it out and fill the pump
witt, mInera/ spirits solvent. If water is left in the pump,
corrosion will shof ten the life of the pump.
Check hydraulic oil sump occasionally. Add as needed.
Change hydraulic fluid after every 2000 hours of opera-
tion or every 12 months, whichever comes first. Also
clean hydraulic pump intake filter and replace the
disposable filter rn the return line. Unplug unit, relieve
pressure. remove shield and follow instructions given
under, “ReplacIng the Electric Motor” to get at filters,
remove old fluid and clean sump. Pour one gallon of
new approved hydraulic fluid into sump through strainer
and turn the unit on and off a few times to remove air
frorn hydraulic system.

Relieve pressure when nor using the unit, to avoid the
pump stalling out at the top of the stroke when starting
up. If the pump stalls: relieve pressure, remove plug
from the top of the hydraulic motor (see illustration
below) and push the spool all the way down. Replace
the cap and start up again.
Periodically, or if electric motor is overheating, unplug
unit, relieve pressure, remove shield and clean all paint,
dirt, dust, etc., off the shield, fan blades, motor and
cooling fins.
Normal seepage of hydraulic fluid past hydraulic motor
piston rod wiper will gradually fill wet-cup. Check wet-
cup after every eight hours of operation to prevent
overflow.
Always wrap the hose around the hose brackets when
storing unit, even if only overnight, to help protect hose
from damage.

Removing Hydraulic Motor For Service
Remove cotter pin from piston rod. See Fig 3. Unscrew
the three tie rod nuts and pull the paint pump down
from the rods. This will also pull the hydraulic motor
piston down. Rotating the paint pump will usually
unscrew the displacement rod from the motor piston;
otherwise use wrenches on the flats. Unscrew the three
tie rods and remove hydraulic motor from support. At
reassembly, be sure that support and motor are
absolutely clean.
See 306-980 for hydraulic motor parts and service
information.
Service Paint Pump (Repair Kit 206-729 available)
To service paint pump, solvent flush unit if pump will
work, turn unit off, relieve pressure and proceed as
follows:
Screw extension tube or union off paint pump intake
valve, take retaining ring out of tube, remove strainer
and put parts in a container of clean solvent. See Fig 3.
Screw intake valve out of housing and remove the pin,
o-ring, ball and guide. See Fig 3. Put parts in solvent to
soak.
Remove the shield and disconnect displacement rod as
explained above. Loosen packing nut, push dis-
placement rod down and pull it out through bottom of
housing with piston. See Fig 3.
NOTE: If displacement rod is seized by dried paint,
remove the packing nut, fill packing cavity
with solvent and let it soak to free rod.
Screw the piston stud out of displacement rod and
remove the ball, packing retainer, glands and packings.
See Fig 3. Put parts in solvent to soak. Screw packing
nut out of housing and remove throat packings and
glands. See Fig 3.
Clean all parts thoroughly with solvent and carefully in-
spect for damage or wear. Inspect insert sleeve in
housing for scratches or mars. If it needs to be replaced,
contact your nearest Grace Factory Branch or Service
Depot. Install new sleeve with tapered end down.
Lubricate displacement rod, packings and insert sleeve,
then reassemble pump using new parts as necessary. If
either seat in piston stud or intake valve housing is
damaged or worn, replace it with a complete new stud
or housing. Tighten piston stud into displacement rod
with 55-75 ft-lb (75-96 N.m) of torque. Leave throat
packing nut loose until pump is completely assembled,
then tighten snugly - don’t get it too tight.
Replacing Electric Motor
If electric motor won’t run and circuit, on-off switch and
fuse are okay, relieve any pressure, disconnect plug
from electric outlet and proceed as follows:
Take the shield off. See Fig 4. Remove the four screws
holding the fan guard to motor and remove the guard.
Loosen the fan blade setscrew and pull fan off motor
shaft. Take off the junction box cover and disconnect
electric cord wires. See Fig 4.

TWO SPRAY GUN HOOKUP
Each line in a two gun system must have a shutoff valve
so one gun can be isolated for servicing while the other
is in operation and a drain valve to relieve line pressure if
gun tip becomes clogged. Ball valve no. 214-711 is
recommended for both purposes. We also recommend
using elbow no. 100-840 to direct outlet flow from drain
valve in a safe direction to a waste container.
In the drain mode, ball valve handle is turned away from
elbow (marked DRAIN on housing); in operating mode,
handle is turned toward elbow (marked CIRC on
housing).
