Liftkar PT I 3
INTRODUCTION
CONGRATULATIONS!
YOUR LIFTKAR PT IS A SAFE AND RELIABLE STAIRCLIMBER.
IT IS DESIGNED FOR THE SPECIFIC PURPOSE OF CONVEYING WHEELCHAIR USERS UP AND DOWN
STAIRS WITH THE ASSISTANCE OF AN ACCOMPANYING PERSON TO OPERATE THE STAIRCLIMBER.
The Liftkar PT is a mobile stairclimber, meaning you can take it with you to use on any stairs. Liftkar gives you
more freedom as a result. At the same time, helpers no longer need to strain their backs on the stairs.
Releasing a lever that is easily accessible without the operator having to bend down lets the Liftkar PT be
dismantled into 3 handy parts: the climber unit (15 kg) and the battery pack and handle unit (4 kg each). All
parts are easy to stow away because they are lightweight and compact.
On stairs the Liftkar PT is remarkably smooth to operate and safe to handle. As a mobility provider, partner,
relative or friend, Sano wishes you all the best in using this stairclimber. We hope you will find this instruction
manual useful in finding out how to operate your Liftkar PT.
In order to update you about product news as well as technical changes (e.g. options, accessories) we ask you
to register your product online.

1 GENERAL SAFETY GUIDELINES
NOTE
Manufacturer information
ATTENTION - POSSIBLE IMPENDING DANGER OR HARMFUL SITUATION
If it is not avoided, slight physical injury or damage to property may result.
WARNING – POSSIBLE IMPENDING DANGER
If it is not avoided, death or serious physical injury could be the result!
DANGER – IMMEDIATE THREAT OF DANGER
If it is not avoided, death and serious physical injury are the result!

Liftkar PT I 5
NOTE
Please read this instruction manual carefully. Follow all instructions in this manual and take
notice of the warning signs and pictograms on the unit. Climbing stairs presents a risk in itself
and not complying with these instructions could cause accidents.
The stairclimber may only be used for the purpose for which it has been designed – transporting
people on stairs.
The Liftkar PT may only be operated by people who
have proof of having been trained in how to operate the stairclimber
can walk upstairs backwards
are both physically and mentally sound
are able to maintain balance without great physical strain.
The LIFTKAR PT must not be operated by
people under 16 years of age
people under the influence of alcohol, drugs or medication
pregnant people
Children are generally not allowed to use the LIFTKAR PT models.
If an accident should occur with the stairclimber, this must be reported to your specialist dealer
immediately (vigilance!).
The optimal driving angle is especially trained during the user training. This depends on
various factors, such as the weight and size of the person to be transported, the type of
wheelchair, etc. The size of the operator also influences the optimal driving angle.
Usually, the optimal driving angle is achieved when the LIFTKAR PT is in balance.

Liftkar PT I 6
ATTENTION
Do not use the Liftkar PT with a passenger until you have practised operating it perfectly
without a payload. Next, try operating it again with somebody as lightweight as possible who is
not disabled. The test passenger should hold onto a handrail or a second person during the
climb.
Always start by using the lowest speed first (setting 1). Do not switch from single step mode to
continuous mode.
Never reach into the transport mechanism with your hands while the battery pack is connected.
(Risk of snagging/squashing).
When transporting the Liftkar PT itself, Sano recommends undoing the lever screw (stays on
handle, so there is no risk of losing it) and taking the stairclimber apart. This will prevent it from
being switched on inadvertently and in this form the Liftkar PT is easier to transport.
The Liftkar PT is supplied with a powerful, replaceable 5 Ah / 24 Volt battery pack, which should
always be fully charged before using the stairclimber. If, for whatever reason, the battery pack
should run out of power while in operation on stairs, move the stairclimber down the stairs and
replace or recharge the battery. It is always possible to move down at least one flight of stairs,
even with an empty battery pack. The first sign of the battery pack running out is indicated by
the stairclimber's performance. The Liftkar PT becomes slower and appears to be struggling.
Inexperienced operators are warned by the LED display: if the battery pack needs to be
recharged the LED display starts flashing, alternating between red and green and an
intermittent acoustic warning signal alerts you.
The following rules apply regarding ambient conditions for storing and operating the LIFTKAR
stairclimber: avoid exposing the stairclimber to high temperatures (above 40°C) such as direct
sunlight or high air humidity (above 70%) as a consequence of using in a sauna area or in the
rain, or similar, due to the risk of damaging the stairclimber as a result of overheating. Likewise,
avoid exposing stairclimber to very low temperatures below 5°C.
WARNING
Always close the safety belt while the stairclimber is in operation, regardless of whether a
person is being transported or not. Under no circumstances should it hang down to the right or
left. Risk of jamming the wheels – danger of falling. Risk of damaging the stairclimber.
For transporting people using Liftkar stairclimbers, only use wheelchairs fitted with a safety belt
or other personnel retention system.
It is essential that passengers who are not able to sit independently are strapped in.
Do not use the stairclimber if unusual noises and/or vibrations occur while the Liftkar
stairclimber is in operation. Withdraw the stairclimber from use and have it inspected by an
authorised specialist.

Liftkar PT I 7
DANGER
Never operate the Liftkar PT on surfaces that are wet, slippery, polished or waxed, smooth, icy
or generally do not give the operator sufficient stability, and impair the braking performance of
the brakes on the transport wheels. Rugs and carpets can also present a risk.
Under no circumstances may you let go of the handle while operating the stairclimber on the
stairs (danger of falling!).
Make sure that nobody is below the Liftkar PT while in operation on stairs (danger of collision!).
Always use te safety belt when transporting people with LIFTKAR stairclimbers. (Risk of injury
due to tipping out)
Make sure you always wear closed, non-slip shoes when operating the Liftkar PT
(danger of falling!).
The use of the stairclimber in explosion-proof areas is prohibited without exception.
2 DESCRIPTION / TECHNICAL DATA
2.1 PT-S MODEL WITH INTEGRAL SEAT
Stair-climbing transport chair with adjustable backrest and armrests
attached to the handle unit. The handle unit, battery pack and climber
unit can be quickly dismantled by releasing a single lever screw (stays
on handle, so there is no risk of losing it). The seat folds down to save
space. Two versions are available for a passenger weight of 130 kg
and 160 kg.
Highly suitable for very steep and narrow spiral staircases because there
is plenty of clearance with the compact design of seat and main wheels
just 200 mm in diameter.
