TRI-FLEX BED - OPERATION MANUAL 5
Major Component Identification
The Impluse Drive System is controlled by a Dynamic Mobility Shark drive controller. This system com-
prises two modules: the power module which is located beneath the bed near the drive wheels, and the
joystick control which is mounted on the headboard of the bed. Become familiar with all controls with the
power button in the OFF position.Adetailed explanation follows.
Shark Joystick Console
1. TURNING THE POWER ON Press the Power button. All indicators will flash briefly. The
current state of battery charge will be displayed and the drive system may be operated as normal.
Note: If the SHARK is turned on while the joystick is out of neutral, an OONAPU (Out Of Neutral At
Power Up) fault will be displayed - refer to table on page 18. Release the joystick back to neutral and
the fault will disappear.
OONAPU (Out Of Neutral At Power Up) is a feature that prevents SHARK form driving if the joystick is
out of neutral when SHARK is turned on or an inhibit condition removed.
This feature prevents sudden and unexpected movements of the bed.
1.1 TURNING THE POWER OFF Press the Power button. The LED's will turn off.
2. SPEED SETTING KNOB The speed knob is used to adjust the top speed of the bed
without a loss of power. It ranges from slow to fast. A low setting (smallest mark on the knob
upward) should be used in tight areas where speed is not required. Ahigher setting of medium to
fast (larger marks on the knob upward) can be used in open areas where higher speeds are manage-
able. PLEASE NOTE: This drive system has a power compensation feature which allows you to
leave the knob set at a lower speed on a ramp, incline, or soft surface and still maintain sufficient
power.

3. BATTERYINDICATOR. The SHARK Information Gauge (located on the joystick con-
sole) is the primary source of user feedback. It displays every possible status that SHARK may
have.
True state-of-battery-charge, including notification of when the battery desperately requires charg-
ing. • Any green LED's lit indicates well-charged batteries.
• If only amber and red LED's are lit, the batteries are moderately charged.
Recharge before undertaking a long trip.
• If only red LED's are lit the batteries are running out of charge. Recharge as soon
as possible.
4. THROTTLE CONTROL JOYSTICK LEVER. The black knob mounted on the top of
the control panel is both the throttle and direction control lever (Push Slowly). Pushing the lever
with your thumb toward the foot of the bed will make the bed go forward or backward accord-
ingly. Pushing the lever slightly will makes the bed begin to move. The further you depress the
lever, the
faster the bed moves. The top speed set by the SPEED KNOB is reached by fully
depressing the joystick lever. Completely releasing the lever will stop power to the motor,
activate the brakes, and you will come to a complete stop. For faster stops in forward,
pull the joystick into reverse until the unit stops moving, then release the throttle.
5. HORN BUTTON
Your unit also comes equipped with a built in horn, activated by depressing the horn
button.
PLEASE NOTE: Should the joystick / brake control system not stop the unit, turning the
power switch off will engage all brakes and stop the unit abruptly. This backup system
should only be used in the unlikely event that the primary brake control is disabled.
6. LOCKING THE SHARK Some SHARKs may be supplied factory programmed with a
LOCK Feature that prevents unauthorized people from turning the SHARK on.
DRIVE LOCKOUT:
While the power is ON, press and hold the Power button for 2 seconds. The horn will sound
a short beep and all LED's will flash briefly. The drive control will then turn off.
The drive system should always be locked when not being used by a health care
professional.

TRI-FLEX BED - OPERATION MANUAL 7
TO UNLOCK DRIVE LOCKOUT:
While the SHARK is locked, press the Power button to turn the SHARK on.All LED's will flash
briefly.The LED's will then perform a right-to-left "chase". Press the Horn button twice before the
timer completes its pass (approximately 6 seconds). The current state-of-charge will then be dis-
played and SHARK may be operated normally.
Note: If the health professional does not press the Horn button twice within the time limit, the
Horn will sound a short beep and SHARK will turn itself off. The unlock sequence must be
completed successfully before the SHARK will drive again normally.
SHARK Information Gauge
The SHARK Information Gauge (located on the joystick console) is the primary source of user
feedback. It displays every possible status that SHARK may have.

CHARGINGTHEDRIVESYSTEMBATTERIES
Charging the batteries is the most important part of operating and maintaining the drive
system. Be sure you do it properly! It is required that only a gel cell or sealed suspended lead-acid
type deep cycle battery be used on the drive system. These batteries do not require water and have
no danger of spillage.
Introduction to Features of the Charger
The charger is fully automatic and has a 24-volt/ 2 -ampere constant current output. It is designed
to operate from a 115vAC line source and provides a constant charging output until the batteries
are fully charged.
The charger is recommended for use with deep cycle, gel or sealed lead acid batteries, and can be
left "on charge" indefinitely without harm to the batteries.
This charger is provided with a Light Emitting Diode (LED) on the front that provides the follow-
ingindications:
1. When the AC is connected to the charger and the charger is connected to the batteries the
greenLED willflash.
2. At full battery charge -the green LED turns to steady on, and the charger goes to a
float mode (charges at a lower rate than the 2-amperes) and continues to monitor the
batteries.
Basic Safety Instructions:
1. Do not expose the charger to rain, snow or other moisture sources (i.e., sprinkler, car wash, etc.).
When storing bed, keep inside a building.
2. Use of the charger in a manner not recommended by the manufacturer may result in the risk of fire,
electrical shock or personal injury.
3. To reduce the possibility of damage to the AC cord or the connector, disconnect the AC line cord by
grasping the plug and not the cord, when disconnecting from the wall or receptacle.
4. Locate cord so that it will not be stepped on, tripped over or subjected to the possibility of damage.
5. An extension cord is not recommended for use with this equipment. Use of an improperly
rated extension cord could result in risk of fire or electrical shock. Should it be required to use an
extension cord, make certain that it is of 3-wire construction and has a wire size of 16-gauge, and
the cord must be in good electrical condition.
6. Do not operate this charger with damagedAC cord or receptacle. If they are damaged, replace
them immediately.

Important Safety Information
BeforeCharging:
Verify that battery terminals are clean and that all charger connections are secure and in good condition.
Grounding and AC Power Connection:
The charger must be plugged into a grounded electrical outlet. The unit is provided with an
electrical cord which contains a conductor for grounding. The charger cord must be plugged into
anAC outlet that is properly installed, and is grounded in accordance with the National Electrical
Code and all local electrical codes and ordinances.
!! WARNING !! - Failure to plug the charger into a grounded receptacle could cause a condi-
tion allowing an electrical shock hazard to be present while charging.
!! WARNING !! Improper connection of the equipment grounding conductor can result in a
risk of electrical shock.
!! CAUTION !! - Never alter theAC cord or plug provided with this equipment. If it does not fit
the outlet, have a properly grounded outlet installed by a qualified electrician.
