Section 1: Safety Precautions
Hale Products, Inc., August 2006 Rev-B
❑
Make sure everyone is clear of the apparatus before shifting to the
PUMP position. Verify the parking brake is set and the wheels are
chocked to prevent any movement of the apparatus.
❑ Make sure proper personal protective equipment is used when operating
or servicing the apparatus.
WARNING!
BE SURE TO WEAR SAFETY GLASSES WHEN REMOVING AND/OR INSTALL-
ING FORCE (PRESS) FITTED PARTS. WEAR PROTECTIVE, HEAT-RESIS-
TANT GLOVES WHEN HANDLING PARTS THAT REQUIRE HEATING FOR
INSTALLATION AND/OR REMOVAL. FAILURE TO COMPLY MAY RESULT IN
SERIOUS EYE OR HAND INJURY.
DO NOT OVERHEAT PARTS CONSTRUCTED OF BRONZE (E.G. IMPELLER).
OVERHEATING (PART TURNS RED OR BLUE) CAN WEAKEN THE PART AND
IT MUST THEN BE REPLACED.
❑ DO NOT operate the system at pressures higher than the maximum
rated pressure. Always use the lowest possible relief valve settings to
enhance operator and equipment safety. Also see Section 2 “Introduc-
tion” on page 19 for additional information.
❑ Relieve all system pressure, then drain all water from the system before
servicing any of its component parts.
❑ Use only pipe, hose and fittings which are rated at or above the maxi-
mum pressure rating at which the water pump system operates.
❑ Per NFPA 1962 requirements, large diameter hose, marked “supply
Hose 3-1/2” to 5” (89 - 127 mm) diameter” shall not be used at operating
pressures exceeding 185 PSI (13 BAR). Large diameter hose, marked
“Supply Hose 6” to 5” (152 mm) diameter” shall not be used at operating
pressures exceeding 135 PSI (9 BAR).
❑
If leakage from the drain hole in the pump head is noticed or suspected,
the mechanical seal must be inspected and/or replaced.
❑
If a pump is operated without water for extended periods, or without dis-
charging water, it could overheat. This can damage the mechanical seal,
impeller or the drive mechanism.
❑ DO NOT attempt to pump until all the GREEN pump indicators in the cab
and panel are ON. Also see Section 3 “Basic Operation” on page 33 for
additional information.
❑
DO NOT advance the throttle unless the OK TO PUMP indicator is ON.
Also see Section 3 “Basic Operation” on page 33 for additional
