FIGURE 5
Hydraulic Shock
• A damaging condition that occurs when a column
of liquid changes direction quickly and increases in
velocity. Weakest point in system will break. Causes
can be sudden loss of power to the driver, valve
closing too quickly, valve closing too slowly allowing
backflow.
Suction Head
• The total head on the suction side of the pump,
including suction lift and friction head.
Total Discharge Head
• The total pressure or head the pump must develop
on the discharge side. It is the sum of THE ELEVATION,
THE SERVICE PRESSURE, and THE FRICTION LOSS. Of
course, all of these measurements must be expressed
in the same units, usually feet of head, before adding
them together.
Water Hammer
• The shock wave or series of waves caused by the
resistance of inertia to an abrupt change of water
flow through a water piping system. Water hammer
may produce an instantaneous pressure many times
greater than the normal pressure. For this reason,
many building codes now require the installation of
a "water hammer arrestor" or accumulation device
to absorb shock waves and prevent damage to
appliances such as washing machines as well as
water treatment components such as reverse osmosis
membranes.

AND SAFETY PRECAUTIONS" SECTION IN THIS
MANUAL.
NEVER STORE ENGINE WITH FUEL IN THE TANK
INDOORS. FUEL AND FUEL VAPORS ARE HIGHLY
FLAMMABLE.
NEVER ADD FUEL WHEN ENGINE IS RUNNING OR
HOT FROM OPERATION. NEVER FILL THE TANK
INDOORS. DO NOT SMOKE WHEN FILLING FUEL
TANK.
AN ADULT MUST ALWAYS HANDLE AND FILL THE
ENGINE WITH FUEL.
ALWAYS HANDLE FUEL IN A WELL VENTILATED
AREA, OUTDOORS, AWAY FROM FLAMES OR
SPARKS.
DO NOT START ENGINE IF FUEL IS SPILLED. WIPE
OFF EXCESS FUEL AND ALLOW TO DRY. REMOVE
ENGINE FROM AREA TO AVOID SPARKS.
MAKE SURE THE UNIT IS IN A STABLE POSITION
BEFORE PULLING THE STARTER HANDLE.
IF ENGINE FAILS TO START AFTER TRYING
STARTING PROCEDURES, PLEASE CONTACT OUR
CUSTOMER SERVICE DEPARTMENT AT 800-345-
6007.
STARTER ROPE CAN CAUSE AN UNANTICIPATED
JERK TOWARDS ENGINE.
INSTRUCTIONS TO AVOID INJURY.
NEVER LEAVE ENGINE
UNATTENDED. TURN OFF AFTER EVERY USE.
NEVER CARRY PUMP FROM ONE LOCATION TO
ANOTHER WHILE ENGINE IS RUNNING.
NEVER RUN ENGINE INDOORS OR IN ENCLOSED,
POORLY VENTILATED AREAS. ENGINE EXHAUST
CONTAINS CARBON MONOXIDE, AN ODORLESS
AND DEADLY GAS.
KEEP HANDS, FEET, HAIR AND LOOSE CLOTHING
AWAY FROM ANY MOVING PARTS ON ENGINE AND
EQUIPMENT.
DO NOT OPERATE PUMP WHEN DISCHARGE IS
BLOCKED OR STOPPED.
DO NOT OPERATE THE PUMP DRY. IF THE PUMP
IS OPERATED DRY THE PUMP SEALS WILL BE
DAMAGED. IF THE PUMP HAS OPERATED DRY,
STOP THE ENGINE IMMEDIATELY. ALLOW THE
PUMP TO COOL AND INSPECT FOR DAMAGE
BEFORE OPERATING AGAIN.
