1 INTRODUCTION
Congratulations on your choice of the Wallenstein Generator. This equipment has been designed and
manufactured to meet the needs of a home owner, business operator or industry that needs electric power
during power outage, at a remote location or any time remote power is needed.
Safe, efcient and trouble free operation of your Wallenstein Generator requires that you and anyone
else who will be using or maintaining the generator, review this Wallenstein Operators manual and
read and understand the Safety, Operation, Maintenance and Trouble Shooting information contained
within this Manual.
All Wallenstein generators are CSA certied and are "neutral bonded to frame" this is a safety feature
that means that the neutral line of the electrical circuit has been bonded to the frame of the generator. The
purpose is to make full advantage of the overcurrent protection device to prevent shocks & electrocution
due to a short circuit from a defective cord or device. In effect this will cause the current from a short circuit
to travel back to the generator and activate the breaker, instead of through a person to ground
The Wallenstein Backup Power Series generator is designed to be a reliable
source of continuous power for the home owner, or recreational use. Utilizing
robust gas powered engines to provide a steady and dependable source of
power, in case of power outage, or when the need arises. The Backup Power
series is intended to be connected directly to the appliance/equipment
requiring electrical power. It is not recommended to connect these
generators to a home electrical system without appropriate equipment and
a qualied electrician to make the connections.
The Wallenstein Jobsite Rated Series generator are designed with the
contractor in mind. Equipped with GFCI protected outlets, these generators
are a safe and dependable source of continuous power on the job site. Small
and portable, the gas powered engines produce a steady and dependable
source of power, for all your power tools. As well having the neutral
conductor bonded to the frame, Jobsite Rated generators feature GFCI
outlet protection, an OSHA requirement when using portable electrical
equipment on job sites.
From home owners, recreational use campers, hunters, snowmobil-
ers, to jobsite contractors, decks, docks, & fence builders, rugged roll-cage frame to stand-up to
jobsite demands, the Wallenstein line-up of generators will get you up and running.
Use the Table of Contents or Index as a guide to locate required information. Keep this manual handy for
frequent reference and to pass on to new operators or owners. Call your Wallenstein dealer or the Distributor
if you need assistance, information or additional copies of the manuals.
OPERATOR ORIENTATION - The directions left, right, front and rear, as mentioned throughout this
manual, are determined when facing the control panel

2.11 ELECTRICAL SAFETY
1. The generator produces enough
electric power to cause a serious
shock or electrocution if misused.
2. Using a generator or electrical
appliance in wet conditions
(rain or snow), or near a pool
or sprinkler system, or when
your hands are wet, could
result in electrocution. Keep the
generator and the immediate
area dry.
3. If the generator has been outdoors, unprotected
from the weather, check all of the electrical
components on the control panel before
each use. Moisture can cause a short circuit
in electrical components that could result in
electrocution.
4. Do not connect to a building’s electrical system
unless an transfer / isolation switch has been
installed by a qualied electrician.
5. NEVER tamper with the factory settings of
the engine or engine governor. Engine speed
controls the frequency portion of the electrical
output (60hZ). Personal injury or damage to the
engine or equipment can result if operating in
speed ranges above the maximum or below the
minimum allowable.
2.10 STORAGE SAFETY
1. Store the unit in a well vented area away from
human activity.
2. If possible, store in a dry area, avoid storage
areas with high humidity, because that promotes
rust and corrosion.
3. Avoid any area where power tools are operated
or spark-producing electric motors.
4. Do not allow children to play on or around the
stored machine.
5. Place the generator on a level surface. Tilting or
laying it on its side can cause fuel or oil leakage.
