Safety Precautions
WARNING
Profhand is intended to be operated in a calm and composed manner, do not use in any other
manner; otherwise there is a risk of accident, overturning the wheelchair, or damaging the
wheelchair. This product is intended for level ground/floor level operation. Do not install any other
assistive power devices.
Do not use the wheelchair if it is damaged or during abnormal circumstances. Such usage could
result in an accident or the wheelchair overturning. If there is a malfunction or abnormality, stop
usage and consult with a dealer.
Do not perform alterations to or dismantle Profhand. Alterations will reduce safety and cause
damage to parts of the wheelchair or cause parts to fall off damaging the wheelchair – could even
lead to an accident or the wheelchair overturning. Therefore, do not willfully make alterations to or
dismantle the wheelchair – if your wheelchair should need maintenance or servicing, please contact
your dealer.
If you are not confident in making adjustments then don’t. Mistakes could result in damage to or loss
of wheelchair parts which could further cause an accident or the wheelchair to overturn. If you are
not confident in making adjustments then consult with your dealer.
Do not use if there hasn’t been a reliable adjustment completed. Otherwise this could lead to an
extra physical burden for the user or even possibly seating discomfort. Adjustments are made to
coordinate with the user’s body condition and to maintain proper posture. Moreover, the user’s
paralyzed part of body should not come into contact with, for example, the frame or any other part of
the wheelchair.
After installation of the wheels, do not use wheelchair until you have ensured that the wheels are
affixed tightly. Wheels that are not affixed tightly have a high risk of falling off and could cause the
wheelchair to overturn. Thus, ensure this is done properly.
During riding, do not touch the quick release buttons for risks of the wheel coming off and the
wheelchair overturning.
Do not place the wheelchair in high temperature places (for e.g. near a heater or hot vehicle). Tires
of the wheelchair risk rupturing due to the extreme heat.
Users with Irritant or sensitive skin conditions are suggested to put on clothing to avoid direct
contacts with parts such as the armrest, backrest, and control lever etc.
Avoid wearing clothing that could easily get entangled in parts of the wheelchair. Clothing that gets
caught in the wheel or leg pedal could cause an accident or the wheelchair to overturn.
Do not grasp/hold to any other modes of transportation to assist in moving for risk of causing
damage to the wheelchair or the wheelchair overturning.
Do not treat the wheelchair as a stool for sitting. There is a risk of losing balance which could result
the user to fall down.
When placing the wheelchair in the car trunk ensure that it is properly set in a fixed position. A
wheelchair that is moving around affects or impedes driving and could also lead to malfunction of
the wheelchair.
Do not stand or sit on the pedals for risk of falling, overturning the wheelchair, and damaging the
wheelchair.
When cleaning do not let wax get on the tires or brakes. When there is wax on the tires or brakes it
is difficult to control the speed thus creating a situation where an accident may occur or the
wheelchair may overturn. If brakes or wheels come into contact with wax, then wipe clean.

Safety Precautions
WARNING
Profhand is not recommended for use outside during heavy rain. Both brakes and tires will be
slippery making it difficult to control the speed – again creating a situation where an accident/crash
or the wheelchair overturning could occur. If brakes and tires should become wet, then use a dry
cloth to wipe dry any wet areas on the tires and brakes.
Do not drive fast downhill to avoid risks of crashing or overturning the wheelchair. Use the brakes to
control the speed.
Do not operate the wheelchair alone on inclines of greater than 10 for risk of accident or wheelchair
overturning. Best to ask someone for assistance to go up inclines.
Do not go on bumpy surfaces for risk of accident, wheelchair overturning and causing damage to
the wheelchair. Do not operate this wheelchair in mountainous areas, sand, wilderness, rivers, water,
mud, rough terrain etc. Best to have someone accompany the user if use in these areas is a must.
Avoid operating the wheelchair on rough surfaces (crossings, sidewalks, uneven surfaces, and
potholes) alone – many different types of surfaces. Both the small and large wheels can get stuck
and damage the wheelchair as well as possibly causing an accident or have the wheelchair rollover.
Do not use on bumpy or rugged roads for risk of damaging the wheelchair, having an accident, and
the wheelchair rolling over. If use in these areas is a must, have someone accompany the user.
Do not walk your pet while driving wheelchair for risk that the pet may drag the wheelchair and
cause an accident or wheelchair may overturn.
Avoid operating the wheelchair by yourself in slippery areas. Construction site panels, slippery wet
surfaces and railway tracks – all of which could lead to an accident or the wheelchair overturning. In
such cases, it is best to ask for assistance.
Do not hold an umbrella while operating this wheelchair. On rainy days wear appropriate clothing for
the rain (raincoat, hat).
When the brakes are in a locked position do not use the wheelchair. Damaged brakes could lead to
an accident or the wheelchair overturning. After unlocking the brakes then you can use the
wheelchair.
Do not let children near the wheelchair when it is not in use. The wheelchair could be pushed over
or the child could be run over by it.
Do not operate wheelchair after intake of drugs or alcohol which decrease motor function, for risk of
an accident such as falling or the wheelchair rolling over.
Do not touch the rotating parts of the wheelchair (wheel, spokes etc.) for risk of user’s hand being
injured by rotating parts.
Do not put anything (e.g. bag) on the back of the wheelchair. If these should come into contact with
the brake cable or control lever cable then this could cause an accident.
Do not use on escalators for risk of having a ‘tumbling’ accident.
Do regular monthly inspections and maintenance of all parts. Without inspections or maintenance
there is risk of equipment malfunction.
When first starting to ride your wheelchair be careful to pay attention to your surroundings. Children
are at risk of having their hands caught in the moving parts.
According to a user’s physical condition, use seat cushion appropriately as there is risk of
developing seat sores.
Do not use the wheelchair as a car seat. Use of the wheelchair seat as a fixed car seat risks
damaging the wheelchair. In vehicles, sit in car seats or another wheelchair seat.

Safety Precautions
WARNING
Avoid using at night for risk of having an accident. Ride on well-lit streets and wear reflective
clothing or carry a night/caution light and bicycle bell.
Have the brakes on, when the wheelchair is stopped, not in use, or when getting on the wheelchair.
If wheelchair starts to move inadvertently, there is risk of falling, rolling or of the wheelchair
overturning - so even for temporary parking ensure that the brakes are on.
Do not use the wheelchair when you are barefoot or wearing slippers or sandals for risk of injuring
your feet. Wear socks and shoes which have a sole and heel when using this wheelchair.
Do not leave outside. Weather or temperature could deteriorate parts rapidly. Put the wheelchair
inside for storage and safekeeping.
Do not let the seat cushion or clothing touch rotating parts (e.g. tires, spokes). This would damage
the clothing or cushion.
Ensure the Velcro straps are fastened properly. Velcro’s strength of attachment and need for
adjustment will change after a certain period of time.
Clean the Velcro of dirt, sand, debris etc. Velcro’s strength of attachment and need for adjustment
will change after a certain period of time.
Do not move the wheelchair until your feet are properly put on the pedal. If the pedal comes into
contact with the floor then it could damage the floor. If you do move the wheelchair while not seated
in it, then remove the pedal first.
Do not put your foot on the chain guard for risk of damaging the chain guard.
Please keep Profhand clean at all time. The cushion and the back pad could be cleaned with
mild/neutral detergent if dirty.
Please do not share the use of Profhand if contagious skin-related disease is present in order to
avoid transmission of infections.
Please do not exceed the loading capacity of 100KG in order to avoid possible damage or danger.
Indoor use of Profhand is suggested. If outdoor use is necessary, please use on smooth surfaces
and ensure caregiver is present at all time and that the surrounding environment is free of danger.

Armrest Adjustment and Inspection
Adjustment - Illustration 2-14, 2-15
Raising the armrest:
1) Grasp the front of the armrest and pull it upwards towards (1) in illustration 2-14. If you continue to
forcefully pull up on the armrest past its final resistance point then you risk damaging it. *The degree
the armrest can move depends on the height of the armrest.
Returning the armrest to resting position:
1) Push the armrest downwards towards (2) in illustration 2-14.
2) Push it down till it will not go down any further. Insert the collar (A) inside the hook to stabilize the
armrest. Illustration 2-15. At this point the armrest will be braced upwards.
3) Ensure that the collar is properly inserted into the hook. *Inside the bracket is a rubber ring and collar,
thus there will be slight movement in this part. (But the armrest itself is immovable.)
WARNING
Do not let the armrest deteriorate. A damaged armrest could lead to the wheelchair
overturning or some other accident.
ATTENTION
Do not lift the wheelchair up by the armrest for risk of the wheelchair overturning or having
an accident.
When the armrest is in an up position, do not ride the wheelchair for risks of clothing getting
caught in the wheelchair and causing an accident. Ensure that the armrest is returned to its
original position before riding.
When raising the armrest or putting the armrest back down to its original position, be careful
not to get your hand or clothes caught in the wheelchair (e.g. bracket or backrest). If so,
there is risk of injury.

Armrest Adjustment and Inspection
Height adjustment: – Illustration 2-16
1) Take off the bolt, nut, washer, and gasket.
2) Align the appropriate adjustable hole with the fixed hole. *Do not use the highest adjustable hole.
3) Affix and tighten using bolt, nut, washer and gasket to the armrest pipe. *Have the gasket put in the
adjustable bracket hole.
4) On the other side of the wheelchair do the same adjustment.
Parts Inspection and Method of Changing Parts: Check to make sure there is nothing unstable or any loose
bolts. Both the rubber ring and collar are items that wear out. So, these should be changed regularly. If there is
an increase in the armrest shaking or the armrest is frequently raised; if this leads to armrest weakening then
consult your dealer.
WARNING
When tightening the bolts go according to the sequence given in the illustration. *When the
armrest is not properly affixed there is a risk of causing an accident.
First, put the gasket in the large adjustable hole and tighten the bolt. *When the armrest pipe is
not affixed properly, then there is a risk of causing an accident. *The spacer lying between the
bolt and the armrest pipe should be tight.
ATTENTION
Do not use the upper most adjustable hole for risk of damaging the armrest pipe.

Tire Inspection:
1) Check for cracks, damage, foreign material on the tires, depth of tread lines in tires and tire wear, etc.
2) When tire(s) is functioning abnormally send it back to your dealer for inspection and repair/maintenance.
3) Check tire pressure to make sure it is normal.
Tire size
Air pressure
Confirm if the air pressure is sufficient – also is the air pressure the same as that of the recommended
imprints on the tire. (example above)
Fill the tire with air by following the recommended air pressure on the tire.
ATTENTION
Do not use leaking tires.
When there is a decrease in tire pressure, there is a risk of having a ruptured tire.
If tire pressure is too low, there is a risk that the tire will separate from the rim.
If the tire pressure is too high due to increased air pressure or heat, then there is a risk of the
tire rupturing.
Adjust both tires to the same air pressure.
Checking Around the Wheelchair:
1) If you think the wheelchair is working abnormally, then do a wheelchair check up – adjustment, cleaning,
add oil, tighten bolts, etc.
2) If you think the axle is working unusually, ensure that an inspection is done, clean and oil the axle.
Other Items for Inspection:
1) Check over screws, bolts, and nuts once a month. Make sure these aren’t loose, falling off, damaged,
or producing unusual sounds.
2) Check around the small wheels once a month. Make sure they are not bent, damaged, producing
unusual sounds, or have wheel rotation problems etc.
3) Every day check your brakes before riding. Check to see if they are responsive. Ensure that nuts, bolts
etc. are not loose and unable to fall off.
4) Every day before riding, ensure the armrest and handles are not wobbly or shaky, nuts and bolts
haven’t loosened or producing any unusual sounds.
5) Inspect the chain if there are any abnormalities – when necessary adjust, clean and oil the chain.
