Device Description
Model P318 Powered Wheelchair is battery powered, front wheel motor
driven and is controlled by the PG power wheelchair VR-2 50amp controller.
The user interface is a joystick. P318 is powered by two 12 VDC 34ah (U1)
batteries. The batteries are charged by a 4A off-board charger connected
with 3-pin Microphone Connector to the charging socket on the joystick. The
approximate driving range on fully charged batteries is up to 28km (18mi).
The chair frame is a rived nut and welded steel construction and includes
two front drive wheels with drive units (including motor, gear, brake), batter-
ies and rear pivoting casters. Depending on users needs, the joystick motor
control is mounted to the left or right armrest. When the user activates the
joystick, the controller receives a signal to release the brakes. With the
brakes released, the wheelchair is allowed to move in the direction the joy-
stick is actuated. When the user releases the joystick, the chair slows to a
stop and the brakes are automatically re-engaged. The solenoid electrome-
chanical brakes allow the user to stop by letting go of the joystick.
The upholstery of the device complies with EN 1021-1/-2:2006: Furniture:
Assessment of the ignitability of upholstered furniture: Ignition source:
Smouldering cigarette/ Match flame equivalent
The device can be operated on dry, level surfaces composed of concrete,
blacktop, or asphalt under normal driving conditions.

SAFETY WARNING
YOUR AUTHORIZED DEALER, PROVIDER, THERAPIST(S), AND/OR OTHER HEALTHCARE
PROFESSIONALS ARE RESPONSIBLE FOR DETERMINING YOUR REQUIREMENT FOR A
SEAT BELT FOR SAFE OPERATION OF YOUR MOBILITY DEVICE.
REQUIRING A SEAT BELT TO SAFELY OPERATE YOUR MOBILITY PRODUCT, MAKE SURE
IT IS FASTENED SECURELY IN ORDER TO REDUCE THE POSSIBILITY OF A FALL FROM
THE MOBILITY PRODUCT.

Warnings
DO NOT use an escalator to move a wheelchair between floors. Serious
bodily injury may occur.
DO NOT lean over the top of the back upholstery to reach objects from
behind as this may cause the wheelchair to tip over.
DO NOT shift your weight or sitting position toward the direction you are
reaching as the wheelchair may tip over backwards or sideways.
DO NOT tip or wheel the wheelchair without assistance, unless you are
highly skilled.
DO NOT attempt to stop a moving wheelchair with wheel locks. Wheel
locks are not brakes.
DO NOT stand on the frame of the wheelchair.
ALWAYS use caution when transferring in or out of the wheelchair. Every
precaution should be taken to reduce the transfer distance. Also be
certain the wheel locks are engaged to prevent the wheels from moving.
Cautions
Riding over curbs or obstacles can cause tipping and serious bodily harm.
If you have any doubt that you can safely cross any curb or obstacle,
ALWAYS ASK FOR HELP. Be aware of your riding skills and personal limi-
tations. Develop new skills only with the help of a companion.
The wheelchair is not designed for weight training and is unsafe for use as
a seat while weight training. Weight training from the wheelchair substan-
tially changes the stability of the chair and may cause tipping.

EMC

Warning: The wheelchair might disturb the operation of devices in its
environment that emit electromagnetic fields (e.g. alarm systems of
shops, automatic doors)
to do so.
