Disclaimers
Dynojet Research, Inc. (Dynojet) makes no representation or warranties with respect to the contents
hereof and specifically disclaims any implied warranties of merchantability for any particular purpose.
Dynojet reserves the right to revise this publication and to make changes from time to time in the
content hereof without obligation of Dynojet to notify any person of such revision or changes.
Dynojet is not responsible for false operation due to unexpected dynamometer operation such as may
be caused by static, software bugs, hardware failure, etc.
Dynojet is not responsible for damage resulting from improper installation of the dynamometer or
from improper service rendered to the dynamometer. Dynojet is not responsible for damage incurred
due to alteration of the dynamometer or components, use of unapproved parts, or abuse to the
dynamometer.
Do not connect or disconnect cables or components on the dynamometer with the power on.
Always wear protective clothing, ear protection, and eye protection (goggles, safety glasses) when
using and servicing the dynamometer.
Equipment Power Requirements
The dynamometer has specific power requirements. Connecting the dynamometer to the incorrect
voltage will void the dynamometer warranty. Installation may require a licensed electrician.
Potentially Lethal Voltages
Components attached to and within the dynamometer operate with potentially lethal voltages. To
provide the greatest assurance of safety, the AC power cord(s) must be disconnected from the power
source before servicing electrical components or wiring. Disconnect all power cords before servicing
electrical components for the greatest assurance of safety.

WARN INGS
Electrostatic Discharge Precautions
Electrostatic Discharge
Electrostatic Discharge (ESD), or static shock, can damage electronic components within the
dynamometer. The damage may occur at the time of an ESD occurrence, or the shock may degrade
the component, resulting in a premature component failure later. To avoid ESD damage, always
practice good ESD control precautions when servicing the dynamometer. Dynojet designs its
dyn amo me ter s t o be ver y t ole ran t o f st ati c sh oc ks by the users, but the electronics are vulnerable when
the electronics are exposed. ESD occurs as a result of a difference of potential between two objects
when the two objects touch. Damage occurs as a result of the energy released when the discharge
(touch) occurs. The difference of potential can accumulate by as simple an action as a user moving
across carpet or a seat. If that person’s energy is discharged directly to the electronics, the electronics
can be damaged.
Precautions
To protect against ESD damage, you must eliminate the difference of potential before the electronics
are handled. Touch the chassis of the dynamometer before touching any of the electronics. By touching
the chassis, you discharge any static shocks to the chassis instead of to the electronics.
If you are holding a circuit board or dynamometer component in your hand when you approach the
machine, touch the chassis of the dynamometer with your hand before installing the circuit board or
component.
When handling a circuit board or component to someone, touch that person with your hand first,
then hand them the component.
Always carry circuit boards in anti-static bags when the boards are exposed (removed from the
dynamometer).
Battery Fire and Explosion Hazards
There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer’s instructions.
Automotive Batteries
In operation, batteries generate and release flammable hydrogen gas. They must always be assumed
to contain this gas which, if ignited by burning cigarette, naked flame or spark, may cause battery
explosion with dispersion of casing fragments and corrosive liquid electrolyte. Carefully follow
manufacturer's instructions for installation and service. Keep away all sources of gas ignition and do
not allow metallic articles to simultaneously contact the negative and positive terminals of a battery.
Do not allow the positive and negative terminals to short-circuit. The dynamometer chassis is tied to
the negative side of the battery. Do not short between the positive battery terminal or the starter
connections to the chassis. In addition, make sure metal tools such as screw drivers, wrenches, and
torque wrenches do not come in contact with the negative and positive terminals of the battery. Short
circuiting the terminals of the battery can cause burn injuries, damage to the dynamometer, or trigger
explosions.
Charging
Batteries being charged will generate and release flammable hydrogen gas. Charging space should be
ventilated. Keep battery vent caps in position. Prohibit smoking and avoid creation of flames and sparks
nearby.
Wear protective clothing, eye and face protection, when charging or handling batteries.

In Ground Model 224 4WD Automotive Dynamometer Installation Guide
WARNINGS
Other Potential Hazards
The AC power outlet shall be installed near the equipment and it shall be easily accessible to allow for
disconnect before service.
The dynamometer should be located in a well ventilated area. There is a carbon monoxide hazard with
all internal combustion engines. Engine exhaust contains poisonous carbon monoxide gas. Breathing
it could cause death.
Always wear proper ear and eye protection when operating the dynamometer.
Never operate the dynamometer with the covers removed.
Never stand behind the dynamometer when in operation.
Never operate the dynamometer when there is excessive vibration or noise. Resolve these problems
before proceeding.
Verify brake operation before beginning any dynamometer testing.
Verify the vehicle is properly secured to the dynamometer.
Never operate the blowers without the guards installed.
Exercise care with any dynamometer testing; portions of the dynamometer and vehicle may become
hot.
As with any equipment using electricity and having moving parts, there are potential hazards. To use
this dynamometer safely, the operator should become familiar with the instructions for operation of
the dynamometer and always exercise care when using it.
Do not repair or replace any part of the dynamometer or attempt any servicing unless specifically
recommended in published user-repair instructions that you understand and have the skills to carry
out.

capable of lifting a minimum of 1905 kg (4200 pounds) to move the crated dyno into
position in your dyno room. Refer to “Dynamometer Specifications and
Requirements” on page 1-4 for more information.
1 Move the crated dyno to a clear area near your dyno room.
2 Using a pry bar, or a large flat screwdriver, and a hammer, carefully remove the
top and sides of the crate.
Note: At this point, you will want to inspect the exterior of the dyno for any
indications of damage. Report any damage immediately.
3 Remove the grates, track assembly, and braces from the top portion of the crate
and set aside.
Note: For clarity, only two grates and one rail are shown in Figure 2-1.
4 Remove the parts and hardware boxes from the crate and set aside.
5 Remove the crate braces that supported the grates.
6 Before removing the dyno from the crate, you will need to install the track
assembly in your pit. Refer to the instructions page 2-3 for more information on
installing the track assembly.
(for clarity, not all
grates are shown)

The following instructions are the same when using both 224 and 248 stationary
dynos. We will use the model 224 pit dyno as the stationary dyno for the following
steps.
Note: The stationary dyno must be installed before proceeding with the 4WD
dyno installation. Depending on the model dyno, refer to the following manuals:

Dynamometers
Before installing the track assembly, layout the entire track assembly in the pit using
the following instructions for position and alignment.
1 Line up the center line of the track assembly with the center line of the stationary
224 dyno.
2 Measure the following distances and set the track assembly in the pit as listed
below and shown in Figure 2-2.
• The track assembly should be 4.50 cm (1.75 in.) from the pit wall.
• The distance between the inside of the rails should be 184.15 cm
(72.50-inches +/- 0.06 in.).
• The distance from the first rail tie assembly to the first rail tie should be
44.77 cm (17.625 in.).
• The distance from the first rail tie assembly to the second rail tie is 94.30 cm
(37.125 in.).
• The distance from the first rail tie assembly to the third rail tie is 143.83 cm
(56.625 in.).
3 Verify the track assembly is square by measuring from corner to corner.
4 Mark and drill all ten holes, five on each side of the track assembly.
5 Set the track assembly aside.
6 Install the Red Head anchors. Refer to Appendix A for installation instructions.
