UNPACKING & SET-UP

UNPACKING

Carefully remove the GPP and its 
power supply from the shipping 
container and examine closely for 
shipping damage. If any parts are 
missing or the unit is damaged, 
notify the transportation company 
and immediately file a claim for 
the amount of damage.  Record 
the model and serial number of 
your electrofisher in the spaces 
provided below:

Model Number: _______________
Serial Number: _______________

When ordering parts, always 
include the power supply model 
and serial number located on the 
unit’s nameplate.  This is essential 
to ensure the correct replacement 
part is shipped to you.  Please 
keep this manual and refer to 
it when making adjustments or 
ordering parts.  Additional copies 
are available for a nominal charge 
from your distributor.

CHOOSING A 
LOCATION

In choosing the best location 
for your GPP, the following 
factors should be taken into 
consideration:

FIRE HAZARDS: 

Locate the 

power supply at least 3 feet 
(1 meter) away from buildings 
or structures.  Keep the power 
supply away from flammable 
trash, rags, lubricants, and 
explosives.  Do not use the power 
supply near any forest, brush, 
or grassland unless the exhaust 
system is equipped with a spark 

arrestor that is effective.  Have a 
fire extinguisher accessible. 

SECURITY: 

Choose a location 

where everyone, especially 
children, can be kept away, 
to protect them from burns 
and electrical shocks.  Take 
precautions to prevent unqualified 
personnel from tampering with or 
attempting to operate the power 
supply. 

SURFACE: 

Choose a level surface.  

If the power supply is tilted, fuel 
spillage may result.

MOISTURE: 

Do not stand the 

unit in water or on wet ground.  
Protect electrical equipment from 
excessive moisture that will cause 
deterioration of the insulation and 
may result in short circuits.

DIRT: 

Install the unit in a clean 

location. Abrasive materials 
such as dust, sand, or lint cause 
excessive wear to both engine 
parts and generator parts.  Grass 
and leaves are a fire hazard. 

COLD: 

Engines should be located 

where the temperature does not 
fall below freezing.  Engines start 
easiest when they are not subject 
to extreme cold.

HEAT: 

The temperature of the 

area where the engine is located 
must not exceed 100°F because 
the engine is air-cooled.  Where 
natural ventilation is inadequate 
install a fan to boost circulation. 

CONFINED SPACE: 

Restricted air 

flow can cause overheating and 
damage the engine and generator. 
Operation in an enclosed 

compartment is also a fire hazard 
and is not authorized.

EXHAUST: 

Whenever an engine 

is used indoors, the exhaust 
must be vented to the outside.  
Exhaust from a gas engine is 
extremely poisonous, containing 
carbon monoxide, an invisible 
odorless gas that can cause 
unconsciousness or death.

AUXILIARY WIRING: 

Use 

sufficiently thick insulated wire to 
hook up to the auxiliary windings.  
The gauge depends on the length 
of the wire, the voltage drop, 
and the amount and kind of load.  
Consult a competent electrician 
and national and local codes.

GROUNDING: 

If grounding is 

called for in local codes, or 
radio interference necessitates 
it, drive a 3/4 or 1 inch pipe into 
the ground as close to the unit 
as possible.  This pipe must 
penetrate moist earth. To the pipe 
connect a ground clamp and run 
a No.10 wire from it to the battery 
negative terminal on the control 
panel, or to the generator ground 
stud.  Do not connect to a water 
pipe or a ground used by a radio 
system.  When used in boats, 
ensure that generator frame is 
grounded to boat hull.  This will 
prevent a shock in the event of an 
electrical failure.

FUEL SHUT-OFF VALVE

The generator has one fuel shut-
off valve. Make sure the valve is 
open for proper operation. It is 
located directly below the choke 
lever.
