ENGINE
The engine is1 HP, two cycle, single cylinder, air cooled
and ges powered. An engineONIOFF switch is located
at the back of the engine. Thefunction of the engine is
to drive the hydraulic pump.
BYPASS VALVE
Thebypassvalvehas
two functions: fl) to assist in
priming the paint pump during
initial startup, and (2)to
provide .positive reliefof paint pressure from the gun,
hose and sprayer.
PAINT PUMP
The paint pump is immersed directly into a paint pailup
to a 5 gallon size, so the pump is actually beingpressure
fed without the mess and troubleof pouring paintinto a
hopper.
Turning thebypass valvecounterclockwise causes the
paint to drain directly back into the paint pail through
the barbed hose fitting. Turning the knob clockwise
causes the paint to flow through the fluid outlet fitting
end to the hose and gun.
HYDRAULIC PUMP
reserThe hydraulic pumpis located inside the hydraulic

SPRAY GUN &
REVERSE-A-CLEAN 111 SPRAY TIP KIT
Thespray gun has a tough, lightweight plastic body.
The gun has a trigger safety lever which prevents accidentally triggeringthe gun when the leveris set in the
safe position. (See WARNINGS, page 4).
The Reverse-A-Clean 111 spray tip kit uses high pressure
fluid to unclog the spray tip without removing it from
the gun. (See page 15.) The kt includes a safety tip
guard which helps reduce the riskof an injection injury.
A No. 315 spray tip for use with latex paints is also
included.

HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
FLUID INJECTION HAZARD
Spray Tip Safety
General Safety
This equipment generates very high fluid pressure. Spray from
the gun, leaks or ruptured components can injectfluid
through your skin and into your body and cause extremely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes or onto the skin can
cause serious damage.
NEVER point the spray gun at anyone or a t any part of the
body. NEVER put hand or fingers over the spray tip.
ALWAYS have the tip guard in place on the spray gun when
spraying.
ALWAYSfollow thePressure Relief Procedure. a?'the
right, before cleaning or removing the spray tip or paint roller
or servicing any system equipment.
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, engagethe gun safety lever
immediately. ALWAYSfollow
thePressureRelief
Procedure and then remove the spray tip toclean it.
NEVER wipe off build-up around the spray tip untilpressure is
fully relieved and the gun safety lever is engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including injection
and splashing in theeyes or on theskin or injury from moving
parts or electric shock, always follow this procedure whenever
you shutoff the pump, when checking or servicing any part of
the spray system, when installing. cleaning or changing spray
tips, and whenever you stop spraying.
1. Shut off the sprayer's engine switch,
NEVER try tostop or deflect leaks with your hand or body.
Be sure equipment safety devicesare
before each use.

Ifany fluid appears to penetrate your skin, get EMERGENCY
MEDICALCAREAT
ONCE. DO NOTTREAT AS A
SIMPLE CUT. Tell the doctor exactly whet fluidwas injected.
Note to Physfclan: Injection in the skin is a traumatic in-
juw. it is
importent to treat the injury surgically
as soon
as possible. Do not deley treatment fo research toxicity.
Toxicity is a concern with some exotic coatings injected
direct/v into the blood stream. Consuitaiton with a plastic
surgeon or reconstructive hand surgeon may be advisable.
2. Trigger the gun to relieve pressure, and then engage the
gun safety lever.
3. Open the bypassvalve ONE turn counterclockwise to
drain paint into the pail.
4. Remove the spark plug wire and secure it so it can't accidentally contact the plug. This prevents the sprayer from
being started unintentionally.
If you suspect thar the spray tip or hose is completely clogged,
or that pressure has not been fuliy relieved after following the
steps above, VERY SLOWLY loosen the tip guard retaining
nut or hose end coupling and relieve pressure gradually,then
loosen completely. Now clear the tip or hose.
Spray Gun Safety Devices
Be sure all gun safety devices are operating properly before
each use. Do not remove or modify any part of the gun; this
can cause a malfunction and result in serious bodily injury.
Safefy Lever
Whenever you stop spraying, even for a moment, always set
the gun safetflever in the closed or "safe" position, making
the gun inoperative. Failure to set the safety lever can result in
accidental triggering, See Fig 3.
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using
incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them to rupture and result in injection or other serious
bodily injury, fire, explosion or propeny damage.
NEVER alter or modify any pan of this equipment; doing so
could cause it to malfunction.
CHECK all spray equipment regularly and repairorreplace
worn or damaged parts immediately.
ALWAYS read and
follow
the
fluid
and solvent
manufacturer's recommendations regarding the use of protective clothing and equipment.

Tip Guard
ALWAYS have a tip guard in place on the spray gun while
spraying. The tip guard alerts you to the injection hazard and
helps prevent accidentally placing your fingers or any part of
your body close to the spray tip.

This sprayer can develop 30110 p s i 1210 bar/ MAXIMUM
WORKIYG PRESSURE. Be sure that all spray equipment and
accworms are rated to wlthstand the maximum working
pressure of this sprayer. DO NOT exceed the maximum working pressure of any component or accessory used in the
system.
Fluid Cornpatibllity
BE SURE that all fluid and solvents used ere chemically compatible with thewetted parts shown in the TECHNICAL DATA
on page 28. Always read the fluid and solvent manufacturer's
literature before using them in this sprayer. Also read
ALUMINUM AND ZiNC MATERIAL HAZARD on
page 1 .
FIRE OR EXPLOSION HAZARD
Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray equipment is not properly grounded, sparking may occur, and the
system may become hazardous. Sparking may also occur
when plugging in or unplugging a power supply cord. Sparks
can ignite fumes from solvents and the fluid being sprayed,
dust particles and other flammable substances, whether you
are spraying indoors or outdoors, and can cause a fire or explosion and serious bodily injury and property damage.
If you experience any static sparking, or feel even a slight
shock STOP SPRAYING IMMEDIATELY. Check the entire
system for positive grounding. Do not use the system again
until the problem has been identified and corrected.
Groundin
To reduce t f e risk of static sparking, ground the sprayer and
a11 other spray equipment used or located in the spray area.
CHECK your local electrical code for detailed grounding instructions for your area and type of eauiment. BE SURE to
ground all of this spray equipment:
1. Sprayer:
a 25 tt (7.6 m) ground wire and clamp is provided with the sprayer. Be sure it is firmly atfached to the
green screw under the gearcase. Connect the clamp to a
true earth ground, according t o your local code. See Fig
4. Also see the WARNING, under GROUNDING on
page 14 if you are using the PTArrow Sprayer to stripe
lines indoors.
2.
Fluid hoses: use only grounded hoses with a maximum of
5CQfeet (150 m) combined hose length to ensure grounding continuity, Refer to Hose Grounding Continuity,
right.
3.
Spray gun: obtain grounding through connection to a
properly grounded fluid hose and sprayer.
4.
Object being sprayed: according to local code,
5.
All solvent pails used when flushing, according to local
code. Use onlymetalpails, which are conductive. Do not
place the pail on a non-conductive surface, such as paper
or cardboard, which interrupts thegrounding continuity,
6.
To maintain grounding continuity when flushing orrelievingpressure, always hold a metal part of the gun firmlyto
the side of a grounded metal pail, then trigger the gun.
Flushing Sahty.
.
..
Reduce the rlsk of lnpctlonInjury, static sparking, or splashing
by following the specific flushing procedure given on page 18
of this manual. Follow the Pressure Relief Procedure on
page 4, and remove the spray tip before flushing. Hold a metal
part of the gun firmly to the side of a grounded meta/ pail and
use the lowest possible fluid pressure during flushing.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of waar,
damage or misuse, the high pressure sprayemitted from it can
cause an injection injury or other serious bodily injury or property damage.
ALL FLUID HOSES MUST HAVESPRING GUARDS1 The
spring guards help protect the hose from kinks or bends at or
close to the coupling which can result in hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check the entire hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings. If any of these conditions
exist, replace the hose immediately. DO NOT try to recouple
high pressure hose or mend it with tape or any other device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment. Do not use fluids or solvents which
are not compatible with the inner tube and cover of the hose.
DO NOT exposethe hose to temperaturesabove 1 W F (@2°CI
below
or
14°C).
Hose Grounding Continuity
Proper hose grounding continuity isessential to maintaining a
grounded spray system. Checkthe electrical resistance of your
air and fluid hoses at least once a week. If your hose doesnot
have a tag on it which specifies the electrical resistance, contact the hose supplier or manufacturer for that information.
Use a resistance meter in the appropriate range for your hose
to check the resistance. If the resistance exceeds the recommended limits, replace it immediately, An ungrounded or
poorly grounded hose can makeyour system hazardous. Also
read FIRE OR EXPLOSION HAZARD, left.
Fueling
NEVER fill the fuel tank while the engine is running or hot or
while indoors. Gasoline is highly flammablel Fuel spilled on a
hot surface can ignite and cause a fire. ALWAYS pour fuel in
slowly to avoid spilling.
. .
Be sure there is no open flame in the area, not even from a
cigarette or pilot light1
Mix the fuel only in an approved container, and be sure the
container cap is screwed on firmly.
Suffocation
NEVER operate the engine in a closed building. The exhaust
contains carbon monoxide,apoisonous,odorless,
invisible
gas which can cause serious illnessand even death if inhaled.
Throttle
NEVER alter the throttle setting which is factory set at the
maximum full load engine speed of 4200-4600 RPM. Tampering with this adjustment can damage the sprayer and will void
the warranty.
United States Government safety standards have been
adopted under the Occupational Safety and Health Act. These standards-particularly the General Standards, Part 1910. and the Construction Standards, Part 1926-should be consulted.

WARNING
1 . Do not place the pump intake in the pail yet.
The wallet sized warning card provided with the
gun should be kept with the operator at all times.
The
card
contains
important information on
reducing the risk of an injection injury, and information should an injection injury occur. Additional
copies of this card are available at no cost.
2. Be sure the spark plug wire is firmly connected to
the spark plug. See Fig 15.
3. Open the bypass valve ONE TURN counterclockwise.See Fig 15. Theengine will not start if the

WARNING
Pressure Relief Procedure
Toreduce the risk of serious bodily injury, including injection splashing in the eyes or on the
skin or injury from moving partsor electric shock,
always follow this procedure whenever you shut
off the sprayer, when checking or servicing any
part of the spray system, when installing, cleaning
or changing spray tips, and whenever
you stop
spraying.
CAUTION
Never attempt to start the engineunless fluid
pressure has been relieved, AND the bypass valve
Is open. Trying to start the engine under loadwill
damage the recoilsystem. If this happens, the
engine must be
returned
to en
authorized
Tecumseh dealer for repair.
4. Turn ON the engine ON/OFF switch. See Fig 15.
1. Shut off the sprayer's engine switch,.
2. Trigger the gun to relieve pressure, and then
engage the gun safety lever.
3. Open
the
bypass
valve
ONE t u r n
counterclockwise to drain the paint into the
pail.
4. Remove the spark plug wire and secure it so it
can'taccidentally
..contact the. .plug.This
prevents
the
sprayer
from being
started
unintensionally.
5. For 8 cold start, close the choke.For a warm start,
open the choke. Hold the sprayer frame with one
hand. Grasp the starter rope firmly, and pull it out
rapidly and smoothly.Continueholdingthe
rope
while it returns. Repeatuntil the engine starts. Refer
to Fig 15.
CAUTION
Letting the rope return too fast may cause serious
bodily injury if it hits someone, and could jam the

adjustment. If so, alsorefer to APPLICATION METHODS, Line Striping with the
PTArrow Sprayer, page 21.
,1. Increase the pressure adjusting knobsetting just until the spray from the gun is completely atomized.
To avoid excessive overspray and fogging, and to
decrease tip wear and extend the
life of the sprayer,
always use the lowest possible pressure needed to
get the desired results.
ROTATE

2. If more coverage is needed, use a larger til; rather
than increasing the pressure.
3. Test the spray pattern. To adjust thedirection of the
spraypattern,engagethegunsafetyleverand
loosentheretaining
nut. Positionthe tip so the
groove is horizontal for a horizontal pattern and vertical for a vertical pattern. Retighten the retaining
nut. See Fig 18.
Clearing a Clogged Tip
1. If you have a Reverse-A-Clean" 111 tip guard
assembly on your gun, and
the tip clogs while spraying, release the gun trigger, engagethe trigger safety lever, and rotate the spray tip handle 180°. See
Fig 18.
2. Disengage the safety lever and trigger the gun
into a
grounded metal waste container. Hold a metal part
of the gun firmly to theside of the container to
reduce the riskof static sparking and splashing. The
fluid pressure should force the obstruction out
of
the tip. Engage the safety lever.
Fig 18
3. Return the handleto the original position, disengage
the safety lever, and resume spraying.
4. If the tip Is still clogged, engage the trigger safety
lever, shut off the engine,andopen the bypass
valve one turn counterclockwise. Disassemble the
tip in the reverse order of assembly (see page 13).
Thoroughly clean all parts in a compatible solvent
and inspect for wear or damage. Replace parts as
needed and reassemble. Be sure to use a new seal
and gasket when changing tips.
5. If you have a tip guard kit on your gun which is not
self-clearing, follow step 4.

APPLICATION METHODS
Line Striping wlth the PTArrow Sprayer
Mark thelines to be paintedbeforesprayingthem.
Snapping a chaulk line works well.
GUN ARM SUPPORT
.y lshown In three posltlonal
/
to
Spray a test pattern on scrappaperorcardboard
check the pattern width. To adjust the width, loosen the
screw of the clamp holding the gunarm support to the
vertical post, Raise the arm support to increase pattern
width and lower it to decrease pattern width. Tighten
the clamp screw before spraying. See Fig 24. Also see
Adjusting the Spray Pattern. page 17.
Use the line guideto follow your chaulk lines. .TO adjust
it, loosen the screwof the clamp holding the line
guide,
and position the guide to suit your needs. See Fig 24.
If the gun is mounted on the right side of the sprayer,
the paintwill be sprayedto the right of the line guide. If
the gun is mounted on theleft side of the sprayer, the
paint will be sprayed to the left of the line guide.
The caster at the rear of the sprayer has e lockring.See
Fig 24. When spraying straight lines, engage the lockring so the caster cannot move. When spraying CUNed
lines, release the lockring so the caster can pivot and
help guide the sprayer.
To avoid heavy buildup a t the beginning and end of a
line, start moving thesprayer before triggering the gun,
and release the trigger just before you stop moving.
Fig 24
~
Curbs can be sprayed by using the gunhas a hand-held
gun (see Preparing
the
PTArrow
Sprayer for
Manuel Spraying, below), orby adjusting the direction
the gun sprays from the gun holder. With the trigger
safetyleverengaged,justloosen
the two capscrews
which hold the gun holderto the gun arm support. Turn
theholder
to .thedesired position and tighten the
screws. See item 243, Detail A, page 29. You may also
need to raise or lower the gun arm support to get the
desired spray pattern. See the second paragraph of this
section.
Preparing the PTArrow Sprayer for
Manual Spraying
Remove the gun from its holder'td use as.a hand-held
gun for manual spraying. With the trigger safety lever
engaged, loosen the black knob on the gun holderand
remove the gun.See Fig 24. Take loops of hose off the
cart hose hanger for more flexibility of movement.
ADJUSTABLE EXTENSION
ROLLER KIT
See separate manualfor
asaembly lnstructlons
Refer also to Manual Spraying, page 21.
Block the wheels of the cart, if necessary. to keep it
from movingwhileusingthe
sprayer for standard
manual spraying.
Paint Roller
The PTArrow Sprayer includes an 18-36 in. Adjustable
Extension Roller Kit. Follow the Pressure Relief Procedura Warning on page 15. Thenremove thegun
from the holder as describedabove.Remove the tip
guard and spray tip from the gun.
RAC 111
Assemble the Kit as instructed in the manuals provided
with it.
Installthe tip gasketandscrewtheswivelinggun

to prevent leaking)
Manual Spraying
Always hold the gun perpendicular to the surface and
keep the guna t an even 12 to 14 in. (300-356
mml from
the surface you are spraying. See Fig 26.
The best way to controlthe rate of coverage is with the
gun tip size. A small tip orifice applies less paint and a
narrower pattern. A larger
tip orifice applies morepaint
and a wider pattern.
Begin movingthe gun in a horizontaldirection at a
steady rate. Start the spray strokeoff the target surface
and pull the trigger as the gun is moving. Then, while
the gun is still moving, and as you approach the other
edge,release the trigger. This method avoidsexcess
paint build-up at the end of each stroke.
Do not try to increase coverage by increasing the fluid
to get
pressure1 Using the lowest pressure necessary
the results you want will help prolong the life of your
sprayer and minimize paint lost by overspray.
For interior corners, such as on a bookcase or inside a
cabinet, aim the gun toward the centerof the cornerto
spray. By dividing the spray pattern this way, the edges
on both sides are sprayed evenly. See Fig 28.
7
DIVIDE SPRAY PAlTERN INTO CORNERS
Fig 28
WRONG
'
I
If there is a wind, angle the spray pattern into the wind
to minimize drifting. Paint from the ground to the roof.
Fig 26
To avoid getting paint onthese objects:
The correct speed for moving the gunwill allow a full,
wet coatingto be applied without runs or sags. Lapping
each stroke about 50% over the previous stroke produces uniform paint thickness. Spraying in a uniform
pattern alternately from right to left, then left to right,
provides a professional finish. See Fig 27.
Shrubs. When next to the house, tie back shrubs from
the surface to be painted with rope and stakes. Then
cover them with a sturdy dropcloth as the painter approaches the area.Remove
thesturdy
dropcloth as
soon as the area is painted to prevent possible damage
to the shrubs.
Concretewalks. If thewalkways will bewalkedon,
cover them with a canvas dropcloth to avoid slipping.
Otherwise a plasticcloth is all that is needed.
Electrical outlets and fighting fixtures. Protect electrical
outlets with masking tape. Cover lighting fixtures with
plastic bags secured with masking tape.
Nearby objects. Move objects such
as automobiles, picnic tables, lawn furniture, etc. upwind of the surface to
be sprayed. In the case of a nearby home, make a protective barrierbyhangingplasticbetween
two long
Doles.
