SET-UP PROCEDURES

This machine is intended for outdoor use only.
Machine must be stored indoors when not in use.

1. Attach a 5/8" water supply hose to inlet connector.

Minimum flow should be 5 gpm.

2. Attach high pressure hose to discharge nipple using

quick coupler. Lock coupler securely into place by pull-
ing back coupler collar and inserting it onto discharge
nipple and then pushing collar forward to lock in place.

3. Attach variable pressure control wand to spray gun

using teflon tape on threads to prevent leakage.

4. Attach swivel connector on high pressure hose to

spray gun using teflon tape on threads.

5. Check oil level on sight glass on side of pump. Oil

should be visible one-half way up sight glass (SAE
30W non-detergent). The oil level can also be
checked by using the dipstick on the top of the pump.

6. Fill gasoline tank and check engine oil.

7. Fill fuel tank. Do not confuse gasoline and fuel oil

(diesel) tanks. Keep proper fuel in proper tanks.

8. Install proper battery making sure that the red cable

is attached to the positive terminal. Use only a group
24 marine type deep cell battery with a 90 amp hour
rating (battery not included). This is for electric start
models only.

9. These machines are intended to be protected from

outside environments.

OPERATING INSTRUCTIONS

(See Component Identification on page 5.)

STOP!

Read operator’s manual before operating this

machine. Failure to read operation and warning instruc-
tions may result in personal injury or property damage.

2. Turn on water at faucet and pull trigger on spray gun

allowing water to flow until all air has discharged from
system. Check for water leaks; tighten as needed.

3. Pull wand coupler collar back and insert desired pres-

sure nozzle into coupler then secure by pushing col-
lar forward.

NOTE:

Variable pressure control wand handle must

be turned clockwise to enable water to flow out of
the high pressure nozzle.

4. Read engine manual, turn on gas valve and choke.

Turn the engine switch to the START position and
hold it there until the engine starts.

NOTE:

Do not

use the electric starter for more than five seconds at
a time. If the engine fails to start, release the switch
and wait ten seconds before operating the starter
again. When the engine starts, allow the engine
switch to return to the ON position. If the engine is to

be started without the battery, turn switch to start
position and pull rope to start. Turn off choke.

CAUTION: Small engines may kick back. Do not hold
pull rope tightly in hand.

5. With spray nozzle pointed away from you or anyone

else, press trigger on spray gun to obtain pressur-
ized cold water spray.

6. For hot water, turn the burner switch ON when a

steady stream of water flows out of the spray gun.
Burner will light automatically.

NOTE:

Do not start machine with burner switch on.

7. To apply detergent, see “How to Use the Detergent

Injector” (page 8).

GENERAL WASHING
TECHNIQUES

1. Hold spray nozzle approximately one foot from the

surface being cleaned. Spray at an angle to get un-
der the material being removed.

2. When washing large objects, use detergent injector to

apply detergent. Start washing from the bottom and
work up. Better detergent economy and faster results
will be obtained by allowing the detergent to set 5 - 10
minutes. After washing, rinse from the top down.

3. Cleaning heavy dirt or material away with a hard

stream of clear water is recommended before using
a cleaning agent.

SHUT DOWN PROCEDURES

1. Rinse all lines (and injector) with clean water to re-

move any soap residue.

2. Turn burner switch off and continue spraying, allow-

ing the water to cool below 100° F.

3. Turn engine off.

4. Turn off water supply.

5. Open spray gun to relieve remaining pressure.

6. Remove water supply hose.

7. In freezing conditions, disconnect water supply and
