The HDR Heater is a direct-fired radiant heater. The machine operates on diesel
fuel. The machine consists of the following components:
Stainless steel combustion chamber
Blower
Single-stage burner
High-temperature shut-down device
Fuel tank
Safety tip switch
Fuel is consumed in a closed combustion chamber. Outside air is pulled into the
machine where it is heated. This clean, dry air is blown between the walls of the
combustion chamber to cool the machine. Access to the blower assembly is
protected by a guard fitted on the air inlet.
The HDR Heater is intended to provide heat on outdoor construction sites and in
other rugged applications. Do not use this machine indoors.
This machine has been designed and built strictly for the intended use described
above. Using the machine for any other purpose could permanently damage the
machine or seriously injure the operator or other persons on the work site. Machine
damage caused by misuse is not covered under warranty.
Optional
accessories
This machine has been designed and built in accordance with the latest global
safety standards. It has been carefully engineered to eliminate hazards as far as
practicable and to increase operator safety through protective guards and labeling.
However, some risks may remain even after protective measures have been taken.
They are called residual risks. On this machine, they may include exposure to:
exhaust emissions
hot surfaces such as exhaust vents and fuel heater
fuel and fuel fumes when refueling
high voltages and arc flash
To protect yourself and others, make sure you thoroughly read and understand the
safety information presented in this manual before operating the machine.

4.6 Positioning the Machine
DANGER
Carbon monoxide. Using the machine indoors CAN KILL YOU IN MINUTES.
Exhaust gas contains carbon monoxide (CO). This is a deadly poison you cannot
see or smell. If you can smell the exhaust, you are breathing CO. Even if you
cannot smell the exhaust, you could be breathing CO.
f NEVER operate the machine inside an enclosed area, such as a home, tunnel,
or garage.
f ONLY use the machine outside and far away from windows, doors, and vents.
These openings can pull in exhaust.
f ALWAYS use a battery-powered or battery-backup CO alarm in nearby struc-
tures. Even when you use the machine correctly, CO may leak into nearby
structures.
f If you start to feel sick, dizzy, or weak after the machine has been running, move
to fresh air IMMEDIATELY. See a doctor. You could have carbon monoxide
poison.
CO Alarms
WARNING
Fire hazard. Do not move the machine while it is plugged in, even if power is lost.
f Turn off the machine, wait 10 minutes, disconnect the power cord, and let it cool
completely.
WARNING
Fire hazard. Machines positioned on a hill or an incline may slide, break away or
roll over.
f Do not position the machine on a hill or an incline.
WARNING
Explosion and fire hazard. Risk of severe injury or death.
f Do not operate the machine near flammable vapors, fuels, or combustibles.
Because this machine produces carbon monoxide (CO), Wacker Neuson
recommends that CO alarms be installed in all structures in close proximity to the
machine. CO alarms provide an extra measure of protection against this poison
that you cannot see or smell.
Install battery-operated CO alarms or plug-in CO alarms with battery backup,
according to the manufacturer’s instructions. CO alarms should be certified to the
requirements of the latest safety standards (UL 2034, IAS 6-96, or CSA 6.19.01).
Test the CO alarm batteries monthly.

Introduction
When
Preparing for
storage
Stabilizing the
fuel
Extended storage of equipment requires preventative maintenance. Performing
these steps helps to preserve machine components and ensures the machine will
be ready for future use. While not all of these steps necessarily apply to this
machine, the basic procedures remain the same.
Prepare your machine for extended storage if it will not be operated for 30 days or
more.
Follow the procedures below to prepare your machine for storage.
Complete any needed repairs.
After completing the procedures listed above, fill the fuel tank completely and add a
high-quality stabilizer to the fuel.
Choose a stabilizer that includes cleaning agents and additives designed to
coat/protect the cylinder walls.
Make sure the stabilizer you use is compatible with the fuel in your area, fuel
type, grade and temperature range. Do not add extra alcohol to fuels which
already contain it (for example, E10).
Use a stabilizer with a biocide to restrict or prevent bacteria and fungus growth.
Add the correct amount of stabilizer per the manufacturer’s recommendations.
Storing the
machine
Perform these remaining steps to store your machine.
Wash the machine and allow it to dry.
Move the machine to a clean, dry, secure storage location. Block or chock
wheels to prevent machine movement.
Use touch-up paint as needed to protect exposed metal against rust.
Cover the machine. Tires and other exposed rubber items should be protected
from the weather. Either cover them or use a readily available protectant.
