SAFETY INSTRUCTIONS
Operation of Chair
1. Always ensure that the power is switched off when getting in or out of the wheelchair.
This will eliminate the possibility of accidentally activating the joystick and causing
injury to yourself or others.
2. Always check that the drive wheels are engaged (drive mode) before driving.
3. Set the speed control knob according to your driving ability and the environment in
which you are going to operate. We recommend that you keep the speed at the
slowest position (fully counter-clockwise) until you are familiar with the driving
characteristics of this vehicle. We also recommend that you use the slowest speed
when using your power wheelchair indoors.
4. Always reduce your speed when making sharp turns.
5. Do not switch off the power when the wheelchair is still moving forward. This will bring
the chair to an extremely abrupt stop.
6. Avoid jerky stop/start motions as this will result in excessive current draw from the
batteries, increased tire wear and the rapid wearing of the gearboxes and motors.
7. To brake in an emergency, simply release the joystick.
Ramps and Curbs
8. When driving up or down ramps, be sure to check that the angle of the slope is less
than 12 degrees (slopes about 1/5). Also check that ramp surface is roughened to
prevent slipping, and that ramp surface is correctly in line with the tires and is wide
enough to allow the tires to pass freely along the ramp.
9. Always climb or descend gradients perpendicular to the slope. Never drive across
the slope or turn sharply on a slope. Check that the slope surface is roughened to
prevent slipping. Do not attempt to climb or descend slope greater than 12
degrees (slopes about 1/5).
10. When driving up curbs, always check the height of the curb to ensure that it does
not exceed 1-1/2” in height. Traverse up or down curbs perpendicular to the curb.
Transfers, Reaching and Bending
11. Transferring on and off the HP-1 requires a good sense of balance. Have an
attendant present at all times until you learn to safely transfer yourself. To eliminate
the possibility of injury, Summit recommends performing the following tasks before
attempting a transfer:

SAFETY INSTRUCTIONS
B
Position chair so that the distance between your power chair and the object to
B which you are transferring is close enough for a safe transfer.
B Turn the power off.
B Ensure that your power chair is not in freewheel mode.
B Flip up or remove armrests.
B Flip up footplate or remove footrest or legrest.
Turn both caster wheels towards the transfer direction to improve power chair
stability during transfer.
12. When reaching, bending or leaning while seated on your power chair, make sure
that you maintain a stable center of gravity to keep the power chair from tipping.
General
13. Always use a seat belt, keep your arms on or inside the armrests, and keep feet on
the footplate at all times.
14. For safety reasons, make sure that your weight does not exceed the recommended
weight limit of the wheelchair. Consult your dealer for the specified weight limits for
your particular model.
15. Do not attempt to lift or move a power chair by any of its removable parts. Personal
injury and damage to the power chair may result.
16. Do not stand on the footplate directly.
17. Never try to use your wheelchair beyond its limitations as described in this manual.
18. Do not operate your vehicle if it is not functioning properly.
19. Do not connect any electrical or mechanical device to the vehicle. Failure to obey
this instruction may result in injury and will void the warranty.
20. Never use electronic radio transmitters such as CB’s, walkie-talkies, portable
computers or cellular phones while using the vehicle without first turning the vehicle
off.
Use While Under The Influence Of Medication Or Alcohol
21. Check with your physician if you are taking any medication that may affect your
ability to operate your power wheelchair safely.
22. Do not operate your HP-1 while you are under the influence of alcohol, as this may
impair your ability to operate your power chair in a safe manner.

SAFETY INSTRUCTIONS
Electromagnetic Interference (EMI) from Radio Wave Sources
The rapid development of electronics, especially in the area of communications, has
saturated our environment with electromagnetic (EM) radio waves that are emitted by
television, radio and communication signals. These EM waves are invisible and their
strength increases as one approaches the source. All electrical conductors act as
antennas to the EM signals and, to varying degrees, all power wheelchairs and scooters
are susceptible to electromagnetic interference (EMI). This interference could result in
abnormal, unintentional movement and/or erratic control of the vehicle. The United
States Food and Drug Administration (FDA) suggests that the following statement be
incorporated to the user's manual for all power wheelchairs like the HP-1:
Power wheelchairs and motorized scooters (in this section, both will be referred to
as powered wheelchairs) may be susceptible to electromagnetic interference
(EMI), which is interfering electromagnetic energy emitted from sources such as
radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios and
cellular phones. The interference [from radio wave sources] can cause the
powered wheelchair to release its brakes, move by itself or move in unintended
directions. It can also permanently damage the powered wheelchair's control
system. The intensity of the EM energy can be measured in volts per meter (V/m).
Each powered wheelchair can resist EMI up to a certain intensity. This is called the
"immunity level". The higher the immunity level, the greater the protection. At this
time, current technology is capable of providing at least 20 V/m of immunity level,
which would provide useful protection against common sources of radiated EMI.
Following the warnings listed below should reduce the chance of unintended
brake release or powered wheelchair movement that could result in serious injury:
1. Do not turn on hand-held personal communication devices such as citizens band
(CB) radios and cellular phones while the powered wheelchair is turned on.
2. Be aware of nearby transmitters such as radio or TV stations and try to avoid coming
close to them.
3. If unintended movement or brake release occurs, turn the powered wheelchair off
as soon as it is safe.
4. Be aware that adding accessories or components, or modifying the powered
wheelchair, may make it more susceptible to interference from radio wave
sources. (Note: It is difficult to evaluate the effect on the overall immunity of the
powered wheelchair).
5. Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and note whether there is a radio wave source nearby.

SAFETY INSTRUCTIONS
TURN OFF YOUR POWERED WHEELCHAIR AS SOON AS POSSIBLE WHEN EXPERIENCING THE
FOLLOWING:
!
!
!
Unintentional motions.
Unintended or uncontrollable direction.
Unexpected brake release.
The FDA has written to the manufacturers of power wheelchairs asking them to test new
products to be sure they provide a reasonable degree of immunity against EMI. The FDA
requires that a powered wheelchair should have an immunity level of at least 20 V/m,
which provides a reasonable degree of protection against more common sources of
EMI. The higher the immunity level, the greater the protection.
Your powered wheelchair has an immunity level of 20 V/m which should protect against
common sources of EMI.
ENVIRONMENTAL CONDITIONS
Environmental conditions may affect the safety and performance of your power
wheelchair. Water and extreme temperatures are the main elements that can cause
damage and affect performance.
A) Rain, Sleet and Snow
If exposed to water, your power wheelchair is susceptible to damage to electronic or
mechanical components. Water can cause electronic malfunction or promote
premature corrosion of electrical components and frame.
B) Temperature
Some of the parts of the power wheelchair are susceptible to change in temperature.
The controller can only operate in temperatures that range between 18 °F (-8 °C) and
122 °F (50 °C).
At extreme low temperatures, the batteries may freeze, and your power wheelchair
may not be able to operate. In extreme high temperatures, it may operate at slower
speeds due to a safety feature of the controller that prevents damage to the motors
and other electrical components.

OPERATION
The power wheelchair is simple to operate. However, we recommend that you read
carefully the following instructions to become familiarized with your new vehicle.
A Word of Caution:
Before you turn the power on, always be aware of the environment that surrounds you to
select your desired speed. For indoor environments we recommend that you select the
slowest speed setting. For outdoor operation of this vehicle we recommend that you
select a speed that is comfortable for you to control it safely.
The following steps are required to operate your vehicle safely with the controller (Fig. 14):
A. Driving:
Joystick
1. Controller ON/OFF Switch
Horn
Battery
Condition
Meter
Press the ON/OFF button (I/O) switch located in front of

2. Speed Control
The speed control knob allows you to set the forward
speed to your desired setting. Turning the speed
Fig. 14
control knob clockwise will set the speed at the faster settings while turning it
counter-clockwise will set the speed at slower settings. The controller sets the
reverse speed, acceleration and deceleration proportionally and automatically for
your safety.
3. Joystick
The joystick controls the direction and speed of your vehicle. Pointing the joystick
away from the neutral position, (center), will move the vehicle in the direction where
the joystick is pointing. The farther away (forward/backward) the joystick is from the
neutral position, the faster the vehicle will go. The farther away to the right/left the
joystick is pointing, the sharper the turn of the vehicle will be. To operate the
vehicle, gently push the joystick in the direction you want to go. Returning the
joystick to its neutral position, (center), will reduce the speed and stop the vehicle
by automatically applying the electromagnetic brakes.
NoBte:
B engaging the joystick. This is a safety feature to prevent sudden starts.
After pressing the controller ON/OFF switch, allow two seconds to elapse before
Gentle operation of the joystick will result in smoother transitions in speed and
direction, while sharp operation of the joystick will result in drastic transitions in
B direction and velocity.
When the wheelchair is in operation, the surface of the controller may become
B slightly hot.
In case of emergency, let go of the joystick and the chair will come to a stop.

OPERATION
B. Controller Display:
The controller display is a multifunction visual display. It can provide three types of
information: i) ON/OFF status, ii) battery condition meter and iii) fault diagnostics.
1. ON/OFF Status
When the power is on, the controller's LED will be lit up. If the LED is not lit, the controller is
OFF.
2. Battery Condition Meter
The battery condition meter is composed of 6 segments (two each of red, orange, and
green). It enables you to monitor battery charge. The battery condition meter indicates
the approximate amount of battery charge left.
B
B
B
Red, orange and green LEDs indicate that the batteries are fully charged.
Red and orange LEDs indicate that you should charge the batteries if possible.
Red LEDs indicate that you should charge the batteries as soon as possible,
because low battery voltage may cause your power wheelchair to become
inoperative.
Note: When the batteries begin to approach a discharged state, the first red LED will
begin to flash slowly, reminding you that the batteries need to be charged immediately.
3. Diagnostics:
The controller's LEDs can also indicate some common causes of problems with your
power wheelchair. The following chart lists possible problems indicated by the flashing
meter:

B
You must turn the controller OFF and then ON again to reset the controller, even
B if the source of the fault is removed/corrected.
If more than one fault exists, then the fault having the highest priority is indicated.
C. Free-Wheeling:
Because the motors are designed to engage the
electromagnetic brakes when the vehicle is not in
use or when the power is OFF, they also have a
manual feature that allows them to "free-wheel".
Free-wheeling is accomplished by turning the free-
wheeling levers to the disengaged position as
shown in Fig. 15.

@
Never free-wheel your power wheelchair on a slope;
Never free-wheel the motors while operating your vehicle;
Always remember to engage the motors before turning the power back ON.
D. Electromagnetic Brakes:
Your power wheelchair comes with an Electromagnetic Brakes, i.e. an automatic
magnetic disc safety brake which is also known as Fail-Safe brakes.
The Electromagnetic Brakes are automatic and work when the power wheelchair is ON
but in a steady state (i.e. Joystick is released to the neutral position), even when the
chair is on a slope. The Electromagnetic Brakes will also be set whenever the power
wheelchair is OFF, but the motor levers are in the engaged (vertical) position.
Note:
Please refer to the section titled “To check brake” in the Maintenance & Repair section
in page 18 to make sure brakes are in good condition.

OPERATION
E. Thermal Protection:
Your power wheelchair controller is equipped with a safety system called thermal
rollback. A built-in circuit monitors the temperature of the controller and motors. In
case of excessive heating of the controller and motors, the controller reduces the
motor voltage and speed of the power wheelchair. The reduction of the speed
allows the electrical components to cool down. Although your power wheelchair will
resume its normal speed when the temperature returns to a safe level, we
recommend that you turn the power off and wait for 5 minutes before restarting to
allow the components to cool down if you find that you have lost speed suddenly.
F. Main Circuit Breaker:
The main circuit breaker is a reset button located on the
front battery box with 2 connectors (Fig. 16). The main
circuit breaker monitors the electric current drawn from
the batteries. It is a safety feature built in your power
wheelchair for your extra safety. When the batteries and
the motors are heavily strained (e.g., from excessive
loads), the main circuit breaker will trip to prevent
damage to the motors and the electronics. If the
circuit breaker trips, wait for approximately one minute
and then press the button to reset it. Then turn on the
controller power, and continue normal operation. If the
main circuit breaker continues to trip repeatedly,
contact your authorized dealer.
Reset Button
Fig. 16
G. Chair Response:
Should the chair’s response not be to your satisfaction, ask your dealer to adjust the
program to a level at which you are comfortable. The program can be altered to
either increase or decrease the response rates for better control of your power
wheelchair.

BATTERIES & CHARGER
BATTERY
We recommend that you use deep-cycle batteries that are sealed and maintenance
free for your power wheelchair. Both sealed lead-acid (SLA) and gel cell are deep-cycle
batteries and are similar in performance. Deep-cycle batteries are specifically designed
to provide power, drain down, and then accept a relatively quick recharge. Lead-acid
batteries should be charged as often as possible.
Specification of the battery that we recommend:
Type:
Size:
Deep-cycle sealed lead-acid or gel cell
U-1
Voltage:
Amp Hours:
12 V each
30-35 amp hours
Depending on the use, terrain and driving conditions, the batteries will provide a range of
15-20 miles of travel. However, even if the power chair is not used, we recommend that
the batteries be charged periodically.
NoBte:
B
Do not use any automotive batteries. They are not designed to handle a long,
deep discharge and also are unsafe for use in power chairs.
The useful life of a battery is quite often a reflection of the care it receives.
CHARGER
The battery charger takes the standard wall outlet voltage (alternating current) and
converts it to VDC (direct current). The batteries use direct current to run your power chair.
When the battery voltage is low, the charger works harder to charge the batteries. When
the batteries are fully charged, the amperage from the charger is almost at zero. This is
how the charger maintains a charge but does not overcharge the battery.
NoBte:
B The surface of the charger will become slightly hot during charging.
B Make sure the fan of the charger works properly for cooling the charger.
The batteries will not be able to be charged after they are discharged to nearly
B zero voltage.
If your charger comes with two settings, 110V or 220V, always make sure you are
using the correct setting before charging.
Warning! Only use the off-board charger that is supplied with your power wheelchair.
Do not use an automotive-type battery charger. Use of any other charging unit voids the
warranty and could result in severe damage to the batteries, the HP-1, and may cause a
fire hazard.

B wall outlet.
Charging
socket
B Turn the controller power OFF.
Connect the charger connector to the control box charging
B socket (Fig. 17).
B Plug the charger power cord into a standard wall outlet.
Turn the charger switch ON. A red and a yellow (if battery
B charge is low) LED will illuminate.
Fig. 17
B When charging is completed, the yellow LED will turn green.
B Turn the charger switch OFF when the batteries are fully charged.
B Unplug the charger power cord from the wall outlet
Disconnect the other end of the charger power cord from the charging socket.
NoBte:
Make sure to unplug the charger from the wall outlet and chair after charging.
Leaving the charger connected to the chair but unplugged from the wall outlet will
B slowly discharge the batteries.
B Always charge your batteries in well ventilated areas.
B The charger is intended for indoor use only. Protect from moisture.
For maximum performance, it is recommended that you replace both batteries at
B the same time if the batteries are weak.
If the chair will not be used for a long period of time, arrange to have the batteries
fully charged for at least once every month.
According to the battery type and condition of the batteries, batteries usually can be fully
charged in 4-10 hours. This will be indicated when the status light in the battery charger
side panel turns green. Charging the battery longer than necessary will not harm the
battery. We recommend that you charge the batteries for 8 to 10 hours after daily use.
Do not charge the batteries for more than 24 hours.

MAINTENANCE & REPAIR
Your power wheelchair is designed for minimal maintenance. However, like any
motorized vehicle it requires routine maintenance. To keep your HP-1 for years of trouble-
free operation, we recommend you follow the following maintenance checks as
scheduled.
DAILY CHECKS
1. With the controller turned OFF, perform a joystick check. Make sure it is not bent or
damaged and that it returns to center when you release it. Visually inspect the
rubber boot around the base of the joystick for damage. Do not handle or try to
repair it.
2. Visually inspect the controller harnesses. Make sure that they are not frayed, cut or
have any exposed wires.
3. Inspect the battery condition meter on the controller to determine if batteries need
to be charged.
WEEKLY CHECKS
1. Inspect the connections by disconnecting the controller and charger harnesses
from the electronics connector housing. Look for signs of corrosion.
2. Ensure that all parts of the controller system are securely fastened to your power
wheelchair. Do not overtighten any screws.
3. Check for proper tire inflation. Your power wheelchair comes with standard flat-free
solid tires. If your power wheelchair comes with optional air tires, make sure to
maintain the pressure of the tires between 30-35 psi.
4. Check the brakes. This test should be carried out on a level surface with at least
three feet of clearance around your power wheelchair.
To check the brakes (Your power wheelchair may move slightly when performing
this test):
B
B
B
Turn on the controller and turn down the speed and response adjustment knob.
After one second, check that the battery condition meter remains on.
Slowly push the joystick forward until you hear the parking brakes click. Immediately
release the joystick. You must be able to hear each parking brake operate within a
few seconds of joystick release.
B
Repeat this test of the brake for the back, left, and right joystick positions.

1. Check the motor brushes. We recommend that
your authorized dealer inspect the brushes every
six months, or sooner if your power wheelchair is
not operating smoothly. If inspection determines
excessive wear on the brushes, they must be
replaced or motor damage will result.
Motor Brush Caps
Warning! Failure to maintain the brushes could
void the power wheelchair’s warranty.

1. Unscrew the motor brush caps (Fig. 18).
2. Remove the brushes.
3. Inspect the brushes for wear (Fig. 19).
4. Replace the brushes if necessary.
New Motor Brush
2. Inspect the state of the battery terminals every six
months. Make sure that they are not corroded and
the connections are tight. Periodically apply a thin
film of petroleum jelly on the surface of terminals to
Guard against corrosion.

PERIODICAL CHECKS
1. Make sure to keep the controller clean while protecting it from rain or water. Never
hose off your power wheelchair or place it in direct contact with water.
2. Keep wheels free from lint, hair, sand and carpet fibers.
3. Visually inspect the tire tread. If less than 1/32", please have your tires replaced by
your local dealer.
4. All upholstery can be washed with warm water and mild soap. Occasionally check
the seat and back for sagging, cuts and tears. Replace if necessary. Do not store
your chair in damp conditions as this will lead to mildew and rapid deterioration of
the upholstery parts.
5. All moving mechanisms will benefit from simple lubrication and inspection.
Lubricate using petroleum jelly or light oil. Do not use too much oil, otherwise small
drips could stain and damage carpets and furnishings etc. Always perform a
general inspection of the tightness of all nuts and bolts.
