Water Supply

CAUTION

Before connecting the water supply to the pump, check your local plumbing code regarding cross-connectionto thewatersupply.

Abackflow preventor. Part No. 801-133, is available to prevent the back flow of contaminated water intothefreshwatersupply. Install upstream from thepump.

DO NOT exceed 160°F (7OOC) inlet water temperature.

Higher’ temperatures will damage the pump packings.

A.Check flow rateof the watersupply. It must be at least 4 gpm or the pressurewasher will not develop full pressure.

6.To check flow rate, time how longit takes to fill a standard five gallonpail; it should take no longer than 1 minute and15 seconds.

Electrical Supply

7.Connect electrical cord to the proper power supply. The electrical service required is single phase, 230V. 60 Hz AC, 20 Amp. Electrical service must include a ground wire. If an extension cord isused, it must have a ground wire and be atleast No. 12 gage wire. Extension cord must notbe over 100 feet long.

START-UP

Use this procedureeach time you start thepressure washer to help ensure the pressure washeris ready to operate and thatyou start it safely.

1.Check pump oillevel. Look at oil levelindicator window through inspectionhole in side of the hood.’ Pumpalso has a dipstick located under hood on topof pump. Oil level should upbeto dot on oil level indicator window and within the notch on dipstick. AddSAE 20 or 30-weight non- detergent oil as necessary. (SAE 30-weight non- detergent oil ispreferred.)

2.Connect pressure washer to watersupply and to proper electrical service as described in set-up.

3.Turn watersupply on and trigger the gununtil water sprays from the tip and all airpurgedis from thesystem.

4.Turn switch on control panelto “ON”

5.Always engage the gun’s triggersafety latch whenever you stopspraying. even for a moment, to reduce the risk of fluid injection orsplashing in the eyes or on theskin if thegun is bumped or triggered accidentally.

6.Most pressure washerspraying is done atfull pressure. If a reduced pressureis desired fora special application, there are twomethods to reduce the maximum output from thepressure washer.

a.Turn the pressure control knob on the unloader counterclockwise, as needed. This method is best if you are operating consistently ata reduced pressure.

b.Turn chemical selector valve to the “OFF” position, then open the adjustable nozzle on the endof the spray wand, as needed. This method is best to quicklyreduce pressurefor a special application.

DO NOT attempt toadjust the adjustable nozzle when the ,spray gun isin use. Besure that the safety latch on the gun is in “ON”the position before adjusting toavoid seriousbodilyinjuryor

7.Always observe the followingcautions to help avoid costly damage toyour pressure washer.

CAUTION

DO NOT allow thepressure washer to idle for more than 10 minutes. The unit is equipped with a thermal relief valve to help avoid the recirculating water from becoming too hot and seriously damaging the pump, but it is a good idea to turn thepressure washer off if you are not spraying or cleaning at least every 10 minutes.

DO NOT run the pumpdry, which will quickly damage the pump.Be sure the watersupply is fully turned on before starting pumpthe.

DO NOT operate the pressure washerwith the inlet screen removed. This screen helps keep abrasive sediment outof the pump, which could clog or scratch the pump.

DO NOTpumpcaustic materials; such materials may corrode and damagethe pumpcomponents.
