Welcome
At Chunc, safety is paramount in the
product’s design, development and
manufacture. Misuse and adverse
environments can lead to potentially
hazardous situations that could result
in injury or even death. It is therefore
essential that the Chunc user manual and
this manual are read prior to performing
maintenance on a Chunc wheelbase/
wheelchair and kept for reference.
At Chunc we also believe in continuous
improvement. If you have any questions
or comments about our customer service,
product literature or products we would
be pleased to receive them. This manual
can be downloaded from www.chunc.

Maintenance Philosophy
Chunc wheelchairs and accessories are of
modular design and can be maintained
using basic tooling as detailed in section
‘tools’. If a fault has been identied and
is beyond repair by adjusting the tting,
the part or parts must be replaced to
maintain the product warranty.
The tting or modication of any Chunc
Component, whether repair, adjustment
or maintenance must be carried out by
Chunc approved engineers, health care
professionals or appointed NHS repairers.
Failure to comply with these instructions
may invalidate the warranty and
endanger the occupant and attendant.
If at any time you suspect a fault or
any of the equipment is damaged or
behaves erratically or you are uncertain
of the wheelchair’s performance it should
not be used until it has been checked by
your Chunc Representative or appointed
NHS repairer.
As required Maintenance
All maintenance, aside from that detailed
below is to be performed as required.
Scheduled Maintenance
Your Chunc product requires periodic
maintenance in order for it to function
correctly and safely. Before transferring
the user, an inspection should be made of
the wheelchair, ensuring all required parts
are xed securely in position, and in good
working order.
Occupant safety
• Never leave an occupied Chunc
wheelchair unattended.
• Never exceed the wheelchair’s
occupant weight limit, or maximum
load capacity, or use for any purpose
outside the manufacturers instructions.
Postural Management
• Chunc wheelchairs are Class 1 medical
devices and must not be used to seat
any person without prior consultation
of a qualied health care professional.
• A qualied health care professional
should be present when tting or
adjusting the Chunc wheelchair and
accessories to an occupant.
• The occupant’s seating posture and
the positioning of adjustable parts
and accessories should be monitored
closely and adjusted as directed by a
health care professional in accordance
with the instructions in this manual.
• Ensure harnesses are tted to the
manufacturer’s instructions and their
adjustment monitored closely.
• Any adjustments should be as directed
by a health care professional and in
accordance with the manufacturer’s
instructions.
Cleaning
All Chunc upholstered parts must be
cleaned following the care label stitched
into the cover. They can be cleaned using
water and commercially available fabric
washing detergents and non-toxic soap
(neutral soap). The padding inside the
upholstery should not be cleaned with
any liquid; only lightly brush to refresh
the surface. Always ensure all mating
Velcro parts are pressed together prior
to washing. Exposed hooked Velcro can
cause damage to items in a wash cycle.
The armrests are covered with closed cell
foam. They can be wiped clean using a
damp cloth. We do not recommend the
use of detergents on these parts.
The wheelchair frame is constructed
from high quality engineering materials
including powder-coated aluminum,
nylon composite moldings and stainless
steel fasteners. It can be cleaned using
water and commercially available
household detergents and non-toxic
soap (neutral soap). Before cleaning the
wheelchair, all upholstery, including the
armrests should be removed. It may
be necessary to use a brush or cloth
to remove embedded dirt or remove
deposits from sheltered areas. Do not
pressure wash or direct hosed water at
bearings.
Safety note: Failure to comply with
these washing instructions may result
in the reduction of performance of your
product. Over a prolonged period this
could constitute a safety hazard.
Extended life, re-use, recycling
and disposal.
Your product is designed and
manufactured with high quality materials
and components, which can be recycled
and reused. When the wheelchair’s life
can be prolonged no further, it can be
easily dismantled into its respective
material groups. Approximately 90% of
the wheel-chair by weight is recyclable.
Consider the environment when
disposing of your old product. Ensure it
is recycled where applicable by giving it
to a recycling organization at the end of
its life.
