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.
NOTE:
FOR PERFORMANCE, SPECIFICATIONS, INSTALLATION AND HOW TO SERVICE THE CHEMICAL
INJECTOR REFER TO THE OPERATING INSTRUCTIONS SUPPLIED BY THE PUMP MANUFACTURER.
WARNING
:
NEVER USE POISONOUS OR CORROSIVE SOLUTIONS AS A CLEANING OR CUTTING AGENT.
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 OPER-
ATING CONDITIONS, THE PULSATOR VALVE SHOULD ALWAYS BE OFF.
NOTE:
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.
CAUTION: 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 REGULA-
TOR 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
1750 PSI (2000 PSI MAXIMUM) FOR 6.5 HP GASOLINE MODELS
2750 PSI (3000 PSI MAXIMUM) FOR 13 HP GASOLINE MODELS
3250 PSI (3500 PSI MAXIMUM) FOR 18 HP GASOLINE MODELS
