Introduction
The Power Assist HD (PMW-PSHD) is designed as an aid to a wheelchair attendant providing power to
aid pushing in otherwise strenuous situations such as up steep hills, etc.
The PMW-PSHD features some ingenious concepts to help the installation and operation of the device.
Some of these are covered by a pending patent.
The PMW-PSHD is designed to work in conjunction with most wheelchairs with seat widths between
16” and 24”.
The PMW-PSHD is dual-wheel (for added stability and traction).
The PMW-PSHD is to be controlled by an attendant with a manual wheelchair and user up to a combined
weight of 400lbs (182kg).
The PMW-PSHD uses a 24V 12ah battery pack, and has a range of up to ten miles between charges.

Safety Procedures
• The PMW-PSHD must not be used solely by the wheelchair user under any circumstances.
• Ensure the PMW-PSHD is installed as far to the rear of the wheelchair as is comfortable for the
attendant to do so.
• When connecting / disconnecting the battery from the motor or the charger make sure both the
power to the charger and PMW-PSHD handle control are switched off.
• Ensure the PMW-PSHD is secured in transit. It is also recommended that the battery is disconnected.
• Ensure that the battery is charged only with the battery charger supplied with the PMW- PSHD.
Using another battery charger may cause damage or injury.
• The PMW-PSHD may be susceptible to certain types of electromagnetic waves. Avoid close
proximity to mobile phones, commercial broadcast towers and emergency services’ radios. Other
household appliances are not known to pose any such risk. If involuntary movement occurs, switch
off of the PMW-PSHD and report this to your dealer.
• The PMW-PSHD should not be used when it is snowing or during heavy rain. This may cause
damage to the PMW-PSHD. PMW-PSHD should not be exposed to damp conditions or direct
sunlight.
Note: Wheelchairs fi tted with attendant cable brakes. On such wheelchairs, the attendant brake levers
should be removed prior to fi tting. If the attendant brakes do not have a separate parking brake facility,
then parking brakes should be added to the wheelchair.

there is no power. Lift up the PMW-PSHD with the red strap and hook the second loop around
the push handle. Please note that failure to lift up the PMW-PSHD when reversing may cause the
pack to fl ip over.
• Maximum Speed: Always set a maximum speed which you are comfortable walking with.
• Pushing the Wheelchair When Not In Use: We recommend that the powerpack is restrained with
the lift-up strap when not in use.
Handle Set Operation
Please note there is a 2-second delay when starting up the PS-HA HD before the wheel will move. Wait
2 seconds before squeezing the trigger.
• Trigger – Squeeze the trigger to propel the PMW-PSHD. The more the trigger is squeezed, the
faster the PMW-PSHD will travel. Release the trigger to stop the PMW-PSHD

Battery Charging and Care
Follow the procedure below step by step:
1. Turn the power switch to (OFF)
2. Lift out the battery pack using the handle on the pack.
3. Plug the charger’s power cord into the mains.
4. Plug the charger’s round plug into the charging socket of the battery pack
5. Switch on the plug socket.
6. The charger’s LED will illuminate orange to indicate the batteries are charging. The charging
duration is about 8 hours. To ensure optimum performance a 12-hour charge is recommended
7. The orange LED will turn green when charging is complete.
8. Turn off the charger, disconnect the power cord and the round plug from the battery pack
Suggestions
1. Do not disconnect the charger cord if charging Is not completed. The battery life will be seriously
shortened or decayed if the battery is repeatedly used without being fully charged. Therefore be
sure to charge the battery fully every time.
2. Always complete the charging until the LED light turns green. NEVER stop charging before it is
complete.

3. When fully charged, the battery charger will still trickle charge the battery to ensure optimum
range.
4. If you do not use your powerpack for a long time, it should be charged at least every week to keep
the battery in a fully usable condition.
5. The ambient temperature will affect charging time. Charging time will be longer in the winter.
6. After charging, do not leave the charger socket plugged into the powerpack, as this will cause a
power drain on the powerpack and temporarily reduce its range.
7. The batteries carry a six month manufacturer’s warranty. This warranty only covers issues relating
to manufacturing faults, and not faults relating to failure to recharge the batteries as instructed
above.
Attention: Please follow the rules below to avoid accidents while charging.
1. Only use the supplied charger, and recharge the battery to its full capacity every time. You may
damage the battery if you use a charger which is not to the correct specifi cation.
2. Never disassemble or modify the charger.
3. Please charge in a well-ventilated space where there is no direct exposure to the sunlight. Do not
charge in surroundings where it is humid or raining.
4. Do not charge in temperatures less than -10°C or higher than +50°C as the charger may not work
well & batteries may become damaged.
Warning
1. Keep away from fl ammable objects while charging as this may lead to fi re or battery explosion.
2. Do not smoke while charging as the battery may release hydrogen gas. Always charge your
battery in a well-ventilated space.
3. Never connect or disconnect the plug or cord with wet hands whilst charging. Do not connect or
disconnect the plug or cord when they are wet, it may lead to electric shock
CHARGER
The charger supplied has an LED which changes colour depending on its status:
• If the LED is lit ORANGE then the charger is switched on and charging
• If the LED is lit GREEN then the charger is switched on and has fi nished the bulk of its charging
and the batteries can be used. However, we recommend that you leave the charger charging for a
couple of hours after the green LED has lit. This will maintain and probably increase the capacity
of your batteries
• The LED will also illuminate GREEN if the charger is switched on but not connected to the
batteries.
