Warnings and Safety Precautions

This warning label appears on all WATERAX pumps to identify safety
hazards as follows:

READ YOUR ENGINE MANUAL!

Before proceeding further, locate and read the engine

manufacturer’s manual. It contains very important safety

information that MUST be read, understood and followed to
safeguard you and your equipment from harm, as well as for
the proper use and care of your engine. Use only fuel and

oil type recommended in the engine manufacturer’s manual.

Always check oil level in crankcase before use.

WEAR EAR AND EYE PROTECTION.

Always wear eye and ear protection when operating the
pump unit. Sound level of the unit: 91 dB(A).

GENERAL WARNINGS:

 Do not operate if mentally or physically fatigued.
 Inspect hoses and piping to avoid burst injuries.
 No modifications and/or alterations may be made to the

pump. Any such modifications void the pump warranty
and can endanger pump operators.

 Do not operate the pump above the maximum rated

pressure. Use only pipe, hose, and fittings rated at or
above the maximum pressure rating of the pump or
system design.

 Slowly close valves. Use slow close valves wherever

possible to safeguard operators and prevent damage
from water hammer.

 Dry weight of the unit: 20 lbs.

READ THE PUMP OWNER’S MANUAL!

The improper use of this pump could result in serious injuries
as well as damage to the unit. Read the MINI-STRIKER
Owner’s Manual before using your MINI-STRIKER pump unit
and follow the safety instructions in this Quick Guide.

NEVER RUN THE ENGINE IN A CLOSED

OR CONFINED AREA. Exhaust gas contains

carbon monoxide which is poisonous to humans.
Avoid inhalation of exhaust gas.

REFUEL ENGINE WITH CARE. Gasoline is
extremely flammable, and gasoline vapor can
explode. Refuel in a well-ventilated area, with the
engine stopped.

NEVER TOUCH ANY EXHAUST SYSTEM

PARTS WHILE ENGINE IS RUNNING. Always

allow enough time, after stopping the unit, for proper
cooling of these parts and surrounding areas.

EQUIPMENT DAMAGE PREVENTION:

 Flush the pump with fresh water if the pump has been

used to pump salty, brackish, high mineral content
water, water containing debris, or foam injected water.
Check that debris is cleared before using the pump
again.

 Always draft water using a suction hose strainer.

1. Fill the fuel tank with recommended fuel grade and

securely replace cap. Check oil level (see engine manual).

2. Connect the suction hose and footvalve strainer, using a

universal hose coupling wrench to tighten coupling firmly.
NOTE: If desired, a suction hose with a footvalve may be

filled at this time to shorten pump priming

! DO NOT allow the strainer to rest on bottom of lake

or riverbed. Check strainer frequently to make sure
that it is not clogged with moss, leaves, etc.

! DO NOT lift strainer from water while the pump is

operating. Use a rope or other means to keep
strainer at proper height, approximately 1 foot (30
cm) below water surface. If strainer is too close to
the water surface, it will draw air and pump may
lose prime.

3. Connect discharge hose, nozzles, etc., to pump, and
tighten firmly with coupling wrench.

4. Prime the pump

Use a WATERAX hand primer. Pump can also be primed by

“jerking” the suction hose until water flows from the pump’s

discharge port.
