Introduction
Congratulations on the purchase of your Cabra! We hope it enhances the way you hunt
and enjoy the outdoors.
Due to the unique design of this vehicle, it has significant differences in operation from
typical cars, trucks, and other off-road utility vehicles. Some of the differences can have
dire consequences if this vehicle is not operated properly.
READ AND BE FAMILIAR WITH ALL ASPECTS OF THIS OWNER’S
MANUAL BEFORE OPERATING THIS VEHICLE.

CABRA OWNER’S MANUAL

Safety
•OPERATOR –The operator of the Cabra must be at least 16 years old and have a valid
driver’s license. They must not be under the influence of drugs or alcohol. The operator
must ensure that all operating guidelines including maximum capacities are being
followed.
•Rollover –The Cabra has a higher center of gravity than a typical car or truck and is
thus more prone to rollover. Extreme care must be taken to not turn sharply, especially
at high speeds. This issue is even more critical with a full load of occupants and the cab
raised up. Overloading the cab of the Cabra will drastically change the design center of
gravity and make the vehicle much more prone to rollover.
Driving on extreme side to side slopes will also cause the vehicle to rollover. The
guidelines for maximum side to side grade is as follows:
-Cab in lowest position: do not exceed 22 degrees side to side slope.
-Cab anywhere above the lowest position: do not exceed 12 degrees side to side
slope.
The side to side slope is indicated by the LEV-O-GUAGE above the steering wheel.
*EVEN IF YOU DON’T EXCEED THE SLOPE GUIDELINES, THE CABRA CAN STILL ROLLOVER IF
YOU MAKE SHARP TURNS. The combination of side to side slopes and sharp turns
is very dangerous.
•Crushing hazard –Because the cab of the Cabra moves up and down, there is an
inherent risk of crushing anyone or anything that is below the cab when it is lowering. By
design there is a safety gap between the bottom of the cab and the base of the vehicle.

CABRA OWNER’S MANUAL
5
Never place objects on the base of the vehicle below the cab as this will diminish the
safety gap.
IF ANYONE NEEDS TO BE UNDER THE CAB FOR MAINTENANCE OR ANY OTHER REASON, THE
CAB SHOULD BE RAISED UP HIGH ENOUGH TO DEPLOY THE 4 SAFETY TUBE LOCKING PINS
AND THE CAB SHOULD BE LOWERED DOWN TO REST ON THE PINS. This is accomplished
using the remote cab raising/lowering switch located inside the charge door. The power
does not have to be on to operate this switch.
Before each use of the Cabra, always make sure the hydraulic hose going into the
hydraulic rams is free to move and that there is no chafing. There is a safety hose burst
valve installed on the rams so that if the hydraulic hose breaks the valve closes and the
cab will not come down. The only way to get the cab to come down in that event is to
restore hydraulic pressure to the hydraulic rams.
Never allow anyone to get under the cab without the tube locking pins
deployed. Even though there are safety features built in, the only thing keeping
the cab from crashing down is the hydraulic rams. It is possible for them to
crack or have a seal blow out.
When lowering the cab from the driver’s seat always check the camera view
on the display to make sure there are no obstructions below. When the cab is
lowering, the image automatically comes up on the display, however, If you are
parked and suspect that people or animals might be below, the camera image
can be brought up by pushing the appropriate button on the display before
lowering.

•Quail seat –No occupants under the age of 16 years old are allowed on the front quail
seat and platform. All occupants shall wear a seatbelt while the vehicle is moving. If a
person steps off of the platform while the vehicle is moving, the front tire
can RUN OVER THEM. The safety gates on the platform are designed to prevent this
hazard. If the gate is opened while the vehicle is moving, the vehicle should go into
regenerative braking and come to a stop on flat terrain. On sloping terrain, the driver will
have to apply brake pedal pressure to come to a complete stop. If occupants are going to
use the quail seat, the gates should be tested by opening the gates and making sure the
vehicle will not move. The switches can get sticky over time and a quick spray of WD40
on the switch will make sure it operates properly.
•Electrocution –The Cabra utilizes a 20 KWH 96-volt DC battery pack. Touching the
bare portions of those power cables or components can cause electrocution resulting in
injury or death. The battery compartment is accessible below the access panel behind the
quail seat. The battery pack can be disconnected by pulling apart the red
battery cable connector below the quail seat. The battery pack must be
disconnected before removing the battery pack access panel or doing any
work on the 96-volt system which includes the motors and controllers. Care
must be taken any time the quail seat cover is raised. The front motor controller and front
motor are accessible from here. The rear motor controller and motor are accessible from
the rear compartment hatch. The battery must be disconnected before handling them.
The main power cables running from the battery pack area to the rear motor controller
run underneath the right-side dog boxes. Do not drill, weld, or cut anywhere on the
vehicle without first consulting UTD. Doing so could cause a direct short on
the 96-volt system and cause electrocution or fire.

•Steering –The Cabra utilizes an electric over hydraulic power steering system. The
shaft from the steering wheel goes through an electric power steering gearbox which
boosts the input power of the driver turning the steering wheel. There is an electronic
control unit next to the steering gearbox which senses the input torque. Care must be
taken when opening the dash panel to not disturb the signal wires which
could cause un-commanded turning while driving. Work behind the dash panel
should only be performed by UTD technicians or those trained on the Cabra.
The output shaft of the electric power steering gearbox turns a hydraulic pump which
then uses hydraulic fluid to actuate the hydraulic ram which turns the wheels. In the event
of a loss of electric power you will still have steering, but it will require much more effort
to steer.
•Brakes –The Cabra utilizes regenerative braking. The position of the foot throttle
determines the speed the motor controllers are constantly working to achieve. The brake
pedal is not linked to this system. The regenerative braking is only determined by the
position of the foot throttle. For example, if the driver pushes the foot throttle to 50%,
the controllers will accelerate the vehicle to approximately 18 mph. If the driver then
releases the throttle to 0%, the controllers will command regenerative braking which
reverses the flow of electricity and charges the battery pack until the vehicle comes to a
stop on flat ground. (If going downhill it will not come to a complete stop without pressing
on the brake pedal.) If the battery pack is fully charged and the vehicle
immediately goes down a steep hill, the battery management system (BMS) will
protect the battery pack from overcharging and will significantly reduce
regenerative braking. Running the Cabra in hybrid mode while the state of
charge (SOC) is above 80% will also reduce regenerative braking. Loss of
electrical power to the motor controllers will completely eliminate
regenerative braking. With little or no regenerative braking, the force required on the
brake pedal is significantly more than a typical modern vehicle since it is a manual
hydraulic brake system without any power assist.

•parking brake –The parking brake is an electrically actuated brake mounted directly
on each electric motor. The parking brake is only actuated when the shifter is in park,
however, if the shifter is moved to the park position while the vehicle is moving,
the parking brake will not engage until the vehicle comes to a complete stop. If
the ignition is turned off, the parking brake is immediately turned on. Turning off the
ignition while the vehicle is moving will damage the parking brakes.
•Guns –Guns must be unloaded and secured in the scabbards or gun racks while the
vehicle is moving.
•Seat belts –All occupants must wear seat belts while the vehicle is moving.
•Driving through water –Do not drive through more than 18” of water. Doing so
may get water into the generator or electrical systems which can cause significant
damage.
•Doors –Cab doors must be closed when the vehicle is moving. The doors are equipped
with electronic locks for safety purposes. The latch is disabled when the cab is raised
above the fully down position to prevent the opening of doors from an elevated position.
