DO NOT ATTEMPT TO OPERATE ANY HIGH PRESSURE WATER JETTER UNTIL YOU
HAVE THOROUGHLY READ AND UNDERSTAND ALL INSTRUCTIONS, RULES AND
REGULATION CONTAINED IN THIS MANUAL. FAILURE TO COMPLY CAN RESULT
IN ACCIDENT INVOLVING FIRE, ELECTRIC SHOCK AND/OR SERIOUS PERSONAL
INJURY. RETAIN OWNERS MANUAL AND REVIEW FREQUENTLY.
WARNING
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
ELECTRIC SHOCK RESULTING IN DEATH CAN OCCUR IF YOU PLUG THIS MACHINE
INTO AN IMPROPERLY WIRED OUTLET. IF THE GROUND WIRE IS ELECTRIFIED,
YOU CAN BE ELECTROCUTED BY JUST TOUCHING THE MACHINE, EVEN WHEN
THE POWER SWITCH IS OFF. A GROUND FAULT CIRCUIT INTERRUPTER WILL NOT
PROTECT YOU IN THIS SITUATION. USE A UL LISTED TESTER TO DETERMINE IF
THE OUTLET IS SAFE.
DO NOT OPERATE POWER TOOLS IN EXPLOSIVE ATMOSPHERES, SUCH AS IN THE
PRESENCE OF FLAMMABLE LIQUIDS, GASES, OR DUST. POWER TOOLS CREATE
SPARKS WHICH MAY IGNITE THE DUST OR FUMES.
ONLY WEAR LEATHER GLOVES. NEVER USE ANY OTHER TYPE OF GLOVE SUCH AS
CLOTH, RUBBER, OR COATED GLOVES. NEVER GRASP A ROTATING CABLE WITH A
RAG. THESE ITEMS COULD BECOME WRAPPED AROUND THE CABLE AND CAUSE
SERIOUS INJURY.
ALWAYS WEAR SAFETY GLASSES AND RUBBER SOLED, NON-SLIP SHOES. USE OF
THIS SAFETY EQUIPMENT MAY PREVENT SERIOUS INJURY.
DO NOT OVERSTRESS CABLES. OVERSTRESSING CABLES MAY CAUSE TWISTING,
KINKING, OR BREAKING OF THE CABLE AND MAY RESULT IN SERIOUS INJURY.
This product can expose you to chemicals including lead, which is known to the
State of California to cause cancer and birth defects or other reproductive harm. For

TO MAINTAIN PRESSURE AND WATER VOLUME.
NOZZLE SELECTION
GORLITZ NOZZLES ARE AVAILABLE IN BRASS OR STEEL WITH NUMEROUS AMOUNT OF JETS. NOZZLES
MADE FROM BRASS MATERIAL SHOULD NOT EXCEED 1500 PSI OF PRESSURE. STEEL NOZZLES ARE
RATED AT 4000 PSI OF PRESSURE. THE AMOUNT OF REAR JETS, WATER VOLUME AND PRESSURE
DETERMINES THE DRIVING FORCE OF THE HOSE.

APPLICATIONS
THE HOSE AND NOZZLE COMPARISON CHART PICTURED ABOVE SHOULD ONLY BE USED AS A GUIDELINE. IT’S SUGGESTED
APPLICATIONS MAY VARY.
FOR A COMPLETE NOZZLE CHART PLEASE VIEW CATALOG OR PRICE LIST.
SPRAY GUN
SOME JETTERS ARE EQUIPPED WITH A STANDARD SPRAY GUN. THE SPRAY GUN OFFERS THE
ADVANTAGE OF CLEANING AUTOMOBILES, TRUCKS, ENGINE BLOCKS, MACHINES ETC.
TO SERVICE YOUR SPRAY GUN, REFER TO THE SPRAY GUN MANUFACTURERS OPERATING
INSTRUCTIONS.
PRESSURE RELIEF VALVE
GASOLINE POWERED JETTERS ARE EQUIPPED WITH A MANUAL PRESSURE RELIEF VALVE. TO RELEASE
PRESSURE IN THE SYSTEM DUE TO A PLUGGED NOZZLE, ETC. ALWAYS SHUT MOTOR OFF FIRST
BEFORE OPENING THE MANUAL PRESSURE RELIEF VALVE.
SAFETY VALVE
GASOLINE DRIVEN JETTERS ARE PROVIDED WITH A MANUALLY ADJUSTABLE POP-OFF SAFETY VALVE
PRECALIBRATED AT THE FACTORY WITH FINAL ADJUSTMENTS TO BE PERFORMED BY THE OPERATOR.
PRESSURE SETTINGS IS ACCOMPLISHED BY TURNING THE SET SCREW NEAR THE VALVE TIP “IN” FOR
MORE PRESSURE AND “OUT’ FOR LESS PRESSURE READING. SOME UNITS ARE ALSO EQUIPPED WITH
A THERMAL RELIEF VALVE WHICH AUTOMATICALLY RELIEVES PRESSURE. WHEN THE TEMPERATURE
RISES TO HIGH.
PRESSURE SETTINGS: 3000 PSI MAXIMUM FOR 389 cc MODELS
3500 PSI MAXIMUM FOR 688 cc MODELS

Gorlitz Jetters Operating & Maintenance Manual 6
LIQUID INJECTOR
THE CHEMICAL INJECTION WITH A FIXED OR ADJUSTABLE FEED RATE SHOULD BE INSTALLED BETWEEN
THE PRESSURE REGULATOR AND THE REEL. THIS ADDED FEATURE PERMITS THE OPERATOR TO ADD A
CLEANING OR SOAP SOLUTION TO THE WATER FLOW. A HIGH/LO NOZZLE MUST BE USED IN ORDER TO
ACTIVATE THE CHEMICAL INJECTOR.
FOR PERFORMANCE, SPECIFICATIONS, INSTALLATION AND HOW TO SERVICE THE
CHEMICAL INJECTOR REFER TO THE OPERATING INSTRUCTIONS SUPPLIED BY THE PUMP
MANUFACTURER.
PULSATOR
THE PULSATOR PRODUCES A SHORT INTERRUPTION OF WATER FLOW NOTICED AS A VIBRATION FELT
THROUGHOUT THE JETTING HOSE (MORE OBVIOUS WITH SMALL DIAMETER HOSE). THIS PULSATION
PERMITS A BETTER HOSE MOVEMENT THROUGH THE PIPE AND ALSO HELPS TO CUT THROUGH
OBSTRUCTIONS WITH EASE. WHEN STARTING YOUR MOTOR UNDER NORMAL OPERATING CONDITIONS,
THE PULSATOR VALVE SHOULD ALWAYS BE OFF.
NEVER USE POISONOUS OR CORROSIVE SOLUTIONS AS A CLEANING OR CUTTING AGENT.
THE PULSATION DIAL OR KNOB SHOULD ONLY BE TURNED IN UNTIL VIBRATION IS ACTIVATED.
CONTINUED TURNING OF THE DIAL OR KNOB WILL DAMAGE THE PUMP.
ONCE IN THE PULSATION MODE, THE OPERATOR SHOULD ALWAYS AND CONTINUOUSLY
MOVE THE JETTER HOSE TO AVOID EXCESSIVE WEAR AND TEAR OF THE HOSE.
PRESSURE REGULATOR
THE PRESSURE REGULATOR KNOB, LOCATED AT THE PUMP, ALLOWS THE OPERATOR TO ADJUST
THE PRESSURE DURING OPERATION. THE ADJUSTMENT SHOULD BE PERFORMED ONLY AFTER
THE MOTOR/ENGINE HAD BEEN STARTED. IT IS RECOMMENDED TO START ELECTRIC UNITS WITH
AS LITTLE PRESSURE AS POSSIBLE TO AVOID TRIPPING A CIRCUIT BREAKER. THEN GRADUALLY
INCREASE TO NORMAL WORKING PRESSURE. ON GASOLINE POWERED MODELS THE PRESSURE
AND RPM OF THE ENGINE ARE DIRECTLY RELATED. LOW RPM EQUALS LOW PRESSURE, HIGH
RPM EQUALS HIGH PRESSURE ON LARGER DIAMETER HOSE. ON SMALLER DIAMETER HOSE
THE PRESSURE REGULATOR MUST BE MANUALLY ADJUSTED TO REACH LOWER PRESSURE
SETTINGS DUE TO LESS WATER VOLUME PASSING THROUGH HOSE. IF DESIRED THE PRESSURE
REGULATOR CAN BE ADJUSTED FROM ZERO TO DESIRED PRESSURE SETTINGS AFTER STARTING
ENGINE AND ATTAINING PROPER ENGINE RPM IN RELATION TO EXPECTED PRESSURE SETTING.
DUE THE HIGH SENSITIVITY OF THESE REGULATORS THEY ARE NOT COVERED IN THE WARRANTY.
PRESSURE SETTINGS: 1250 PSI (1500 PSI MAXIMUM) FOR 2 HP ELECTRIC MODELS
2750 PSI (3000 PSI MAXIMUM) FOR 389 cc GASOLINE MODELS
3250 PSI (3500 PSI MAXIMUM) FOR 688 cc GASOLINE MODELS
MACHINE SETUP CHECK LIST
GORLITZ JETTERS SHOULD BE GIVEN THE BEST OF CARE. IF KEPT CLEAN AND LUBRICATED, THEY
CAN PROVIDE MANY YEARS OF TROUBLE-FREE SERVICE. THE FOLLOWING INSTRUCTIONS SHOULD BE
CAREFULLY OBSERVED AT ALL TIMES:
• CHECK FUEL SUPPLY ON GASOLINE OPERATED JETTERS.
• TEST GFCI ON ELECTRIC DRIVEN JETTERS.
• CHECK OIL LEVEL AT PUMP.
• CHECK WATER INLET STRAINER.
• CHECK JETTING HOSE FOR KINKS OR EXCESSIVE WEAR.
• CHECK ALL HOSE AND REEL CONNECTORS.
• CHECK JETTING NOZZLE FOR ANY CLOGGED HOLES.
• CHECK FOR ADEQUATE WATER SUPPLY.
WATER FLOW RATE:
3 GPM MINIMUM FOR 2 HP ELECTRIC MODELS
5 GPM MINIMUM FOR 389 cc GASOLINE MODELS
7 GPM MINIMUM FOR 688 cc GASOLINE MODELS
REPAIR OR REPLACE ANY UNSAFE PART WHICH MAY CAUSE THE JETTER TO MALFUNCTION.

GENERAL OPERATING INSTRUCTIONS
1. ATTACH MINIMUM 5/8” DIA. GARDEN HOSE TO WATER FAUCET AND FLUSH HOSE.
2. CLOSE WATER FAUCET.
3. ATTACH GARDEN HOSE TO WATER INLET VALVE AT THE PUMP.
4. CONNECT JETTER HOSE TO REEL OR PUMP DISCHARGE CONNECTOR.
5. ATTACH NOZZLE FINGER TIGHT PLUS TURN 1/2 TURN MAX. WITH WRENCH.
6. APPROXIMATELY 6 FEET FROM NOZZLE MARK HOSE WITH ELECTRICAL TAPE, ETC.
7. OPEN WATER INTAKE AND DISCHARGE VALVES AT PUMP.
8. OPEN WATER FAUCET AGAIN TO PRIME PUMP, FLUSH JETTER HOSE AND NOZZLE.
9. PUSH JETTER HOSE INTO THE DRAIN PIPE UNTIL HOSE MARKER DISAPPEARS, IF POSSIBLE.
10. START THE MOTOR/ENGINE.
11. ADJUST PRESSURE WITH THE PRESSURE REGULATOR KNOB.
12. START JETTING.
TO NEGOTIATE TIGHT PIPE TURNS OR DIFFICULT WASTE LINE BLOCKAGES IT MAY BE NECESSARY
TO ROTATE OR TWIST THE HOSE NEAR THE DRAIN OPENING. ONCE YOU HAVE CUT THROUGH THE
BLOCKAGE, PULL HOSE BACK SEVERAL FEET. PASS HOSE AGAIN THROUGH SAME STOPPAGE
LOCATION AND ADVANCE TO NEXT LARGER DRAIN LINE CONNECTION. SLOWLY RETRIEVE HOSE
FROM DRAIN PIPE TO ALLOW A THOROUGH CLEANING JOB.
ONLY THE LARGER DIAMETER HOSE IS CONNECTED TO THE REEL. THE SMALL DIAMETER
HOSE MUST BE COMPLETELY REMOVED FROM THE REEL BEFORE ANY CONNECTIONS CAN
BE MADE.
FOR ADDITIONAL INFORMATION ON HOW TO START YOUR ENGINE REFER TO THE
ENGINE OPERATING MANUAL SUPPLIED BY THE MANUFACTURER.
