1. SAFETY
Read and comply with all safety items in this manual before operating the pump. Only fully trained
personnel may operate or maintain pump.
If EN 1028 is applicable to the user, the end user must maintain the equipment in an operational
condition, as per regulation 5 in the Provision and Use of Work Equipment Regulations 1998.
1.1. Safety Headings
DANGERS, WARNINGS, CAUTIONS, or NOTICES that immediately precede a step apply directly to that
step and all sub steps. DANGERS, WARNINGS, CAUTIONS, or NOTICES that precede an entire proce-
dure apply to the entire procedure. DANGERS, WARNINGS, CAUTIONS, and NOTICES consist of two
parts: a heading (that identifies possible result if disregarded) and a statement of the hazard (that
provides the minimum precautions). NOTES are used to highlight operating or maintenance proce-
dures, practices, conditions or statements that are not essential to protection of personnel or
equipment. NOTES may precede or follow the step or procedure, depending upon the information
and how it pertains to the procedure/step. The headings used and their definitions are.
INDICATES A HAZARDOUS SITUATION, WHICH IF NOT AVOIDED WILL RESULT IN SERIOUS
INJURY OR DEATH.
INDICATES A HAZARDOUS SITUATION, WHICH IF NOT AVOIDED COULD RESULT IN SERI-
OUS INJURY OR DEATH.
INDICATES A POTENTIALLY HAZARDOUS SITUATION, WHICH IF NOT AVOIDED MAY RE-
SULT IN MINOR OR MODERATE INJURY.
ADDRESSES PRACTICES NOT RELATED TO PERSONAL INJURY.
NOTE
Highlights an essential aspect of an operating or maintenance procedure, condition, or
statement and/or provides pertinent ancillary information.
1.2. Training
Pump Training is available through the Hale Training Academy and may be accessed via the Hale
Products Inc. website (www.haleproducts.com), Godiva √erified Training (godiva.co.uk), or through
your local dealer or vehicle manufacturer.
1.3. Safety Summary
The following warnings are used in this manual. A booster pump is not a complete machine and safe-
ty as well as performance is impacted by installation as well as use.
A PRESSURE HAZARD MAY EXIST EVEN WHEN THE PUMP IS NOT RUNNING. PRIOR TO
REMOVING HOSES, OR CAPS FROM PUMP CONNECTIONS, RELIEVE PRESSURE BY OPEN-
ING DRAINS. BLEEDER VALVES SHOULD ALSO BE USED WHEN CONNECTING TO AN IN-
TAKE FROM PRESSURIZED SOURCE.

2
ALWAYS FOLLOW LOCAL GUIDELINES FROM THE AHJ AND THE APPARATUS MANUFAC-
TURER.
ALWAYS FOLLOW PROPER OPERATING PROCEDURES. THE PUMP OPERATOR AND INDI-
VIDUALS AROUND THE APPARATUS MUST BE FAMILIAR WITH THE PUMP OPERATING IN-
STRUCTIONS AS WELL AS OTHER OPERATING GUIDELINES FOR THE APPARATUS, AND
ACCESSORIES.
ALWAYS STOP THE ENGINE, SET THE PARKING BRAKE, AND CHOCK THE WHEELS BE-
FORE GOING UNDER THE TRUCK FOR ANY REASON.
DO NOT EXCEED OPERATING PRESSURE LIMITS OF PUMP, INSTALLED PLUMBING,
HOSE(S), OR EQUIPMENT IN USE.
DO NOT LEAVE THE DRIVERS POSITION IN THE CAB OR OPEN THE THROTTLE UNLESS
ALL SAFETY INTERLOCK INDICATORS ARE ILLUMINATED.
DO NOT REACH INSIDE THE PUMP SUCTION WHEN THE ENGINE IS RUNNING. CONTACT
WITH MOVING COMPONENTS MAY RESULT IN SERIOUS INJURY. DO NOT REMOVE OR AL-
TER GUARDS.
OPEN AT LEAST ONE DISCHARGE VALVE SLIGHTLY TO PREVENT THE PUMP FROM OVER-
HEATING. IF THE PUMP RUNS COMPLETELY CLOSED, IT MAY HEAT THE WATER ENOUGH
TO SCALD A PERSON.
OPERATORS, INSTALLERS, AND MAINTENANCE PERSONNEL MUST BE TRAINED AND
QUALIFIED FOR ALL THE ACTIVITIES THEY PERFORM.
THE PUMP SHIFT CONTROL AND PUMP SHIFT INDICATOR SYSTEM ON THE APPARATUS
MUST BE INSTALLED IN ACCORDANCE WITH MANUFACTURERS INSTRUCTIONS AND
REGULATIONS SUCH AS NFPA.
ALL BOOSTER PUMPS WEIGH OVER 100 LBS. USE APPROPRIATELY RATED LIFTING
EQUIPMENT. IMPROPER LIFTING (OR UNDERRATED EQUIPMENT) RESULTS IN A
STRIKE/CRUSH HAZARD.
ALWAYS USE PROPER PPE. OIL MAY BE TOXIC. DISPOSE OF OIL PROPERLY PER AHJ
GUIDELINES.

3
DO NOT REPLACE FASTENERS WITH OTHER THAN HALE PART NUMBERS PROVIDED.
FOLLOW DEPARTMENT PROCEDURES TO SET WHEEL CHOCKS WHEN PUMPING.
USE PPE TO PROTECT HANDS AND FINGERS FROM SHARP EDGES. THE EDGES OF THE
BLADES ON THE INDUCER OR IMPELLER MAY BE SHARP.
ALLOWING INTAKE PRESSURES TO FALL BELOW ESTABLISHED LIMITS MAY RESULT IN
DAMAGE TO THE WATER SUPPLY PIPING WHEN PUMPING FROM HYDRANT.
BEFORE LAY OUT AND INSTALLATION OF THE DRIVELINE, CONSULT APPARATUS AND/OR
DRIVELINE COMPONENT MANUFACTURER FOR GUIDANCE AND REFER TO HALE SB90
FOR ALIGNMENT OF DRIVESHAFT AND PUMP DRIVE.
CHECK MAGNETIC DRAIN PLUG FOR DEBRIS. IF SIGNIFICANT METAL FRAGMENTS ARE
PRESENT, REPORT CONDITION TO AHJ SO SERVICE CAN BE PERFORMED.
DO NOT ALLOW A WHIRLPOOL AT THE SUCTION STRAINER WHEN DRAFTING.
DO NOT EXCEED 15 DEGREE ANGLE IN OPERATION OF PUMP SYSTEM.
DO NOT EXCEED POWER TRAIN LIMITS WHEN INSTALLING A PUMP. A MEANS TO CON-
TROL THE ENGINE OUTPUT WHEN PTO IS ENGAGED SHOULD BE CONSIDERED.
DO NOT OPERATE PUMP WITHOUT SUCTION STRAINER IN PLACE.
DO NOT OPERATE PUMP WITHOUT WATER OR WITHOUT DISCHARGING WATER FOR EX-
TENDED TIME, IT MAY OVERHEAT CAUSING DAMAGE.
DO NOT RUN ENGINE HIGHER THAN 1200 RPM DURING PRIMING.
DO NOT RUN THE PRIMER FOR MORE THAN 45 SECONDS. IF PRIME IS NOT ACHIEVED IN
30 - 45 SECONDS, STOP AND LOOK FOR AIR LEAKS OR BLOCKED SUCTION HOSE.
DO NOT USE THE RED IDLE BUTTON UNLESS AN EMERGENCY AS DEFINED BY THE AHJ
EXISTS.

4
FAILURE TO INSTALL THE ENGINE SPEED INTERLOCK SYSTEM PROPERLY MAY RESULT
IN PTO DAMAGE.
FOLLOW PTO AND VEHICLE MANUFACTURER PTO INSTRUCTIONS.
HALE PUMPS ARE SHIPPED WITHOUT OIL. FILL GEARBOX WITH FLUID LISTED IN TABLE 5
BEFORE OPERATION.
IF THE DISCHARGE PRESSURE DOES NOT INCREASE, AND INTAKE GAUGE READING
DOES NOT FALL BELOW ZERO (0), OR THE PRIMING PUMP DOES NOT DISCHARGE WA-
TER TO THE GROUND WITHIN 30 SECONDS, STOP THE PUMP AND CHECK FOR AIR
LEAKS.
OPEN AT LEAST ONE DISCHARGE VALVE SLIGHTLY TO PREVENT THE PUMP FROM OVER-
HEATING. OVERHEATING CAN DAMAGE THE PUMP SEAL, AND OTHER PUMP PARTS.
PUMP ASSEMBLY HAS BOTH METRIC AND SAE HARDWARE.
PUMP DISCHARGE PRESSURE SHOULD INCREASE WITH ENGINE SPEED WHEN OPENING
THROTTLE. IF ENGINE SPEED INCREASES WITHOUT INCREASE IN PRESSURE, THE PUMP
MAY BE CAVITATING.
