Preface
AATA International is an innovative and dynamical company, specialised in stair climbing
equipment. Stairrobots are active in over 30 countries worldwide.
This manual is written for machine operators and for technician who take care for the
maintenance of the machine. Although the tiniest details are not set out, the manual is a
useful help for people who are dealing with the machine on a daily basis.
The stairrobot SR 450 has been used for over 20 years by many well-known companies and
transport contractors worldwide who are involved in the movement of heavy loads into and
out of customer’s premises.
The stairrobot SR 450 is designed to carry unit loads weighing up to 350 kg up-and down
stairs.
This manual should be used in conjunction with the cd-rom instruction video, which is
placed on the inside of the manuals cover.
Read this manual and view the instruction cd-rom carefully before putting the SR 450 into
operation. Always take note of the safety rules as mentioned in chapter “safety”.

2.4.1 Battery indicator
• Batteries 90 -100 % charged
• Batteries 60 -90 % charged
• Batteries 30 –60 % charged
• Batteries almost empty
When the red light is on do not discharge the batteries
any further as this will result in damage to the batteries. If on a
stairway; descent the machine and charge batteries.
2.5. Battery charger
The charger comes with a 1,5 mtr cable to connect the
charger with the stairrobot.
The batteries will be charged automatically if the 24V
connector is plugged in the stairrobot.
The indication led on the charger with the inscription ‘float,
boost’ will turn red / orange if the batteries need recharging
and will turn green if the batteries are fully loaded; the
charger will then go into trickle mode.
Float, boost indicator:
batteries discharged; charger mode: boost
batteries half full; charger mode: boost/float
batteries full charged; charger mode: trickle, float
The robot can be charged directly from a truck or van with a
specially designed transformer.

4. Safety
4.1. General safety precaution
• It is not permitted to make alterations to the
machine.
• Everybody who is working with the machine
has to be acquainted with the safety rules and
has to act upon them.
• Always check the surroundings for safety
where the stair-robot will be deployed.
• Assure that the angle of the stairs is not more
than 45 º
• Make sure that no operator or other person is underneath the (loaded) Stairrobot
during operation

• Secure the working area using warning boards or blocking ribbon
• To avoid misuse by unauthorised persons,
don’t leave the machine unattended.
• Within the path of the machine there may be
no obstructions.
• Make sure the environment of the machine is
dry, clean and illuminated sufficiently.
• With the machine in operation it is forbidden to
be within the operation area of this apparatus.
• Before taking the machine into operation the
machine operator has to be certain that
nobody is located within the operating area of
the machine.
• If the machine is used into the darkness, the
operation position has to be illuminated
sufficiently (about 50 lux).
• The machine may only be used for the
intended activities.
• Inspection and maintenance activities have to
be done before operation
• During inspection and maintenance the
machine may not be used for other purposes
• The local action and safety rules have to be
acted upon.
• Make sure never to walk under the robot

handle and adjust the
extension frame to the load
dimensions; lock handle
again
5.2. Unlocking and retracting folding wheel
• To unlock the folding wheel; push lever towards handle. Push the folding wheel
downwards until it locks into position
• To retract the folding wheel; push lever towards handle; the folding wheel will swing up
and lock automatically
• Important! If you retract the folding wheel make sure that you are out off the swing-
range

5.3. Pre-use inspection
To ensure proper working and safe condition of the SR 450 StairRobot:
• Check that no rubber blocks on the tracks are severely damaged or torn off
• Check the drive-tooth side of the tracks for exposed stringing cords or damage
• Check that nothing has been trapped between the tracks and the robot
• Check that the batteries are fully loaded (battery charge indicator)
• Check that the castor of the folding wheel moves free
• Check that the two fixed wheel can move free
• Check that the lever of the folding wheel permits the folding wheel to drop and lock in
its position for horizontal moving
• Move the control handle left and right causing the tracks to move forward and
backward, listen for excessive sounds ;If a defect is found do not use the machine
until the Stair-Robot is repaired.
• Unlock the handle of the extension frame and check if the extension frame will move
up and down
If there are no defects found the machine is ready for use. If a defect is found do not use the
machine until the Stair-Robot is repaired.
5.4. Loading
5.4.1. The correct position of the load
• If the load is not placed in the correct position on the platform,
the Stair robot can get instable during the process of climbing or
descending a staircase. This can cause the robot to fall down
the stairs resulting in serious damage and injuries.
• The objective is to create an optimal centre of gravity position for the loaded stairrobot
considering the ‘weight distribution’ of the load
• Before positioning the load on the
platform the centre of gravity of
the load has to be determined

Manual Stair Robot SR 450
Publication: 10-05-01
Page 14 of 25
AATA INTERNATIONAL B.V.
• Position the load on the platform
with the centre of gravity of the
load towards the front (in positive
area)
• Position the load with the centre
of gravity of the load as low as
possible to the lifting platform.
• The centre of gravity of the load should
be within the positive area between the
tracks.
