Consultationwith a plastic surgeon or reconstructive hand surgeon may be advisable.

Pressure Relief Procedure

To reduce the riskof serious bodily Injury, includingfluid injectionandsplashing in theeyesorontheskin, always follow thisprocedure whenever you stop spraying for more than10minutes, when shutting down, and before checkingorrepairingany part of the system.

1.Engage the trigger safety latch.

2.Turn thesprayer off.

3.Disconnecttheelectricalsupply.

4.Shut off thewatersupply.

5.Disengagethetriggersafetylatch and trigger the

gunto relieve pressure, and then engage the trigger safety latch again.

EQUIPMENT MISUSEHAZARD

General Safety

Any misuse of thepressurewasheroraccessories, suchasoverpressurizing, modifying parts,using

incompatible chemicals and fluids, or using wornor damaged parts, can causethem to rupture andresult in fluid injection, splashing in the eyesor on the skin, or other serious bodily injury, fire, -explosionor property damage.

NNE R alter or modify any part ofthis equipment; doing so could cause itto malfunction.

CHECK all sprayequipmentregularly and repair or replace worn or damaged park immediately.

System Pressure

This sprayer can develophigh operating pressure. Be sure thatall spray equipment and accessories ratedare to withstandthe maximum workingpressure of this

sprayer. DO NOT exceedthemaximumworking pressure of any component or accessory used in the

system.

Chemical Compatibility

BE SURE that all chemicalsused in thechemical injector are compatiblewiththewettedparts ofthe

hose, gun, wand andtip, as given in the Technical Data (inside back cover). Always read the chemical

manufacturer's literature before using any chemicalin

HOSE SAFETY

Highpressurefluid inthe hoses canbevery dangerous. Ifthe hose develops aleak, split or rupture dueto any kind of wear, damage or misuse,the high pressure spray emittedfrom it can causefluida injectioninjuryor other seriousbodily injury or property damage.

ALL FLUID HOSES MUST HAVE STRAIN RELIEFSON BOTH ENDS. The strain reliefs help protect the hose from kinks or bends at or close to the coupling, which can resultin hose rupture.

TlGHTEN all fluid connectionssecurelybefore each 'use. High pressurefluid can dislodge a loose coupling or allow high pressure spray to be emitted fromthe coupling.

NNER use a damaged hose. Beforeeach use, check entire hose forcuts, leaks, abrasion,bulgingcover, or damage or movement of thehose couplings. If any of these condRions 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 thehigh pressure fluid.

HANDLEANDROUTEHOSES CAREFULLY Do notpull onhosestomovethepressure washer. Do not use chemicals which are not compatible wlth innerthe tube

and cover of the hoseDO. NOT expose Gracohoseto temperatwes above 2M)" F (93' G)M below -40'F

(-400 C).

MOVING PARTS HAZARD

Moving partscan pinch oramputatefingersorother

body parts. KEEP CLEAR ofmoving parts when starting or operating the pressurewasher.

NNER operate the pressurewasher withoutall guards and interlocks installed andfunctioning.Followthe

PressureRelletProcedure before checking or servicing the pressurewasher to prevent discharging high pressure fluid from the gun.

Check for Shipping Damage

Check the unit forany damage that mayhaveoccurred in shipping. Not@ thecarrier Immediately ifthere is any damage.

Installtheappropriatespray tip on thewand.See lnstaliing and ChangingSpray Tips. If you are using a sandblaster kit, seeits separate manual forinstallation instructions.

Set Up

Beforepluggingin the unit,be sure theelectrical service matchesthespecification in TechnicalData (inside back cover) and the voltagelabel on the unit. With the. , unit off, plug the power supply cord into a grounded,

GFCi-protected outlet. Donotremovethe electrical plug whichcomeswiththeunit or bend connecting prongs tofit an improper outlet! Use an extensioncord that meets the requirementsof the EXTENS/ONCORD

section andis no more than100 fl(30 m) long. Added length of cord will affect current draw of unit.

If you areusinga downstream chemical injector,installit betweenthepumpunloader and the high pressure hose, using the quick couplers provided.

Connectthehighpressurehosebetweenthepump

outlet and the gun inlet. Both of these connectionsare made with quick couplers. 1-

CAUTION

Up lo 100 ft (30m) of high pressure hose may beused. Longerhosesmayaffectsprayer

and chemicalinjector performance, if used.

Connect to Water Supply

CAUTION

Before attachingto the water supply, check your

local plumbing code regarding cross- connectionto the water supply.

A backilowpreventer, P/N 801-1 33, isavailable to prevent backflow of contaminated water Into the fresh water supply. Install it upstream from the pump.

Install a regulatingwater valve,P/N 800-258, if inlet water pressureis over ???0psi (4.1 bar).

Do notexceed 160?? F (70" C) inlet water temperature.

Connect ahose with at least a3/4 inch (19 mm) IDand

not longer than50 fl(15 m) to the unit's 314 Inch garden hose inlet.

NOTE m e watersourceatthe unit must havea minimumflowrate equalto that of the unit (see Technical Data, inside back cover).

CAUTION

DO NOT allow the pressure washerto idle for more than10 minutes. Doingso may causethe recircuiating water lo overheat and seriously damage the pumpTum. off the pressure washer if itwill notDe sprayingor cleaningat leastevery 10 minutes.If heated inlet wateris used, reduce this timefurther.

DO NOT run the pump dry, which will quickly damage the pumpBe. sure the watersupply is fully tumed on before starting the pump.

DO NOT operate the pressure washer with the inlet water screen removed. This screen helps keep abrasivesediment out of the pump, which could clog or scratchthepump,Keepthis

screen clean.

DO NOT pump caustic materiais;such materials may corrodethe pump components.
