SAFETY INSTRUCTION
Operation of Chair
1. Always ensure that the power is switched off when getting in or out of the
wheel-
chair. 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 your speed at the slowest position (fully press the deceleration button)
until you are familiar with the driving characteristics of the 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 the will result in excessive current draw
from the batteries, increased tire wear and the rapid wearing of the gear
boxes 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 10 degrees (slopes about 1/6). Also check that ramp
surface is roughened to prevent slipping. Never drive across the slope or
turn sharply on a slope.
9. When driving up curbs, always check the height of the curb to ensure that it
does not exceed 1-1/2” (40mm) height.
Transfers, Reaching and Bending
10.Transferring on and off the P20RTL requires a good sense of balance. To
elimi-
nate the possibility of injury, We recommend performing the following
tasks before attempting a transfer:
→ Position chair so that the distance between your power chair and the
object to which you are transferring is close enough for a safe transfer.

4
→ Turn the power off
→ Ensure that your power chair not in freewheel mode.
→ Flip up or remove armrests
→ Flip up footplate or remove footrests
→ Turn both caster wheels towards the transfer direction to improve power
chair stability during transfer.
11.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
Always use a seat belt, and keep feet on the footplate at all the
time.
12. 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.
13.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.
14.Do not stand on the footplate directly.
15.Never try to use your wheelchair beyond its limitations as described in this
manual.
16.Do not operate your vehicle if it is not functioning properly.
17.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.
18.Never use electronic radio transmitters such as CB, 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
19.Check with your physician if you are taking any medication that may affect
your ability to operate your power wheelchair safely.
20.Do not operate your vehicle while you are under the influence of alcohol, as
this may impair your ability to operate your power chair in a safe manner.
Electromagnetic interference (EMI) from Radio Wave Sources
1.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 wave are invisible and their strength increases as one

5
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). The 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 P20CL
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
wheel-
chair, 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 wheel-
chair).
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. Power wheelchairs and motorized scooters (in this section,
both will be referred to
as powered wheelchairs) may as susceptible to electromagnetic interference
(EMI),
which is interfering electromagnetic energy emitted from sources such as
radio stations, TV stations, amateur radio (HAN) transmitter, 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 inten-
sity 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
“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

6
injury:
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.
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 at least 20 V/m, which provides a reason-
able 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
tempera-
ture. The controller can only operate in temperature that range between
18℉(-8℃) and 122℉(50℃).
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.

A. 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 freewheeling
position.(See Fig 24)
Warning !
→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.
(Fig 24)
B. 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 brake.
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 when-
ever 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 21 to make sure brakes are in good condition.
C. 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, the controller reduces the motor voltage and speed of the power

15
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.
D. Main Circuit Breaker:
The main circuit breakers reset button located near the seat of the back
side on the main frame.(Fig 26) The main circuit breaker monitors the
electric current drawn from the battery. It is a safety feature built in your
power wheelchair for your extra safety. When the batteries and motors are
heavily strained (e.g., from excessive loads),the main circuit breaker will
trip to prevent damage to the motor and the electronics. If the circuit
breaker trips, wait for approximately one minute and then depress 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.

BATTERY & 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 charge as
often as possible.
Specification of the battery that we recommend:
Type:
Size:
Voltage:
Amp Hours:
Deep –cycle sealed lead-acid or gel cell

12V each
62 amp hours
Depending on the use, terrain and driving conditions, the batteries will provide
a range of 12-18 miles of travel. However, even if the power chair is not in use,
we recommend that the batteries be charged periodically.
Note:
→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.

MAINTENANCE & REPAIR
Your power wheelchair is designed for minimal maintenance. However, like
any motorized vehicle it requires routine maintenance. To keep your HP7RTL
for years of trouble-free operation, we recommend you follow the following
main-
tenance 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 over tighten 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)
→Turn on the controller and turn down the speed and response adjustment
knob.
→After one second, check that the battery condition meter remains on
condition.
→Slowly push the joystick forward until you hear the parking brakes click
then
immediately release the joystick. You must be able to hear each parking
brake operate within a few seconds of joystick release
→Repeat this test of the brake for the back, left and right joystick positions
SEMI-ANNUAL CHECKS

20
1.Check the motor brushes. We recommended that your authorized dealer
inspect the bushes 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.
Warning! Failure to maintain the brushes could void the power
wheelchair warranty.
To inspect or replace the motor brushes:
1.Unscrew the motor brush caps. (See Fig 27)
2.Remove the brushes.
3.Inspect the brushes for wear (See Fig 28)
4.Replace the brushes if necessary.
New Motor Brush Worn Motor Brush Motor Brush caps
(Fig 27) (Fig 28)
1. 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 mechanism will benefit from simple lubrication and inspection.
