This manual contains information that is
very important to know and understand.
This information is provided for SAFETY
and to PREVENT EQUIPMENT PROBLEMS.
To help recognize this information,
observe the following symbols.

Danger indicates
an imminently

hazardous situation which, if not avoided,
will result in death or serious injury.

Warning indicates
a potentially

hazardous situation which, if not avoided,
could result in death or serious injury.

Caution indicates a
potentially

hazardous situation which, if not avoided,
may result in minor or moderate injury.

Notice indicates

important

information, that if not followed, may
cause damage to equipment.

1. Know the pump application,

limitations, and potential hazards.
Read these rules and the instructions
carefully. Failure to follow them could
cause serious bodily injury and/or
property damage.

Do not use to pump flammable
or explosive fluids such as
gasoline, fuel oil, kerosene, etc. Do not
use in flammable and/or explosive
atmospheres. Pump should only be used
with liquids compatible with pump
component materials. Failure to follow
this warning can result in personal injury
and/or property damage.

2. Observe all safety precautions for the

handling of the fuel.

Do not refuel a hot engine.
Fuel spilled on a hot engine
could result in a fire or explosion. Do not
refuel a running engine.

3. Pump should be located and should

rest on a level solid foundation. Do
not suspend pump by means of the
discharge pipe.

Be sure pump is on

secure footing so it

doesn’t fall over.

4. Do not use torches or apply excessive

heat, fire or flames to this pump as an
explosion may result.

5. Before working on the unit, insulate

the wire from the spark plug,
disconnect the spark plug wire and
mount it on the grounding clip.

Complete pump

and piping system

MUST be protected against below
freezing temperature. Failure to do so
could cause serious damage and voids
the warranty.

6.

Do not run pump dry. Water is
required to lubricate the shaft
seal.

7. Pumping chemicals or corrosive

liquids with this pump may shorten

the life of the pump and may be
hazardous to the operator.

8. Personal Safety:

a. Wear safety glasses at all times

when working with pumps.

b. Keep work area clean, uncluttered

and properly lighted; replace all
unused tools and equipment.

c. Keep visitors at a safe distance from

the work area.

d. Make workshop child-proof with

padlocks, master switches, and by
removing starter keys.

9. Always use a suction strainer with this

pump to filter large material.

This pump is designed to be self-
priming when installed and operated as
specified below.

1. The pump should be placed as close

as possible to the liquid being
pumped. A pump with 20 foot
suction lift will not remove water as
quickly as a pump with 5 foot
suction lift (Figure 1).

2. Suction hose and fitting must be

airtight.
