5 OPERATORS PROCEDURE
5.1. Pre-use inspection
To ensure proper working and safe operation of the SR 1750 HE StairRobot:
• Check that there are no exposed wires in either the main lead or the pendant control
• Check that both the main plug and the continental 16 amp plug and socket are all
secure
• Check that the pendant cable is secure in the pendant and at the machine end
• Check that no cable has been deformed. If a deformation is found the use of the
machine should be postponed until the cable has been repaired
• If on the dolly; drive the robot of the dolly on a flat surface, listen for excessive or
unusual noises from any part of the machine
• Check that the ramp will raise to it’s full extend and that it’s not leaking oil. When fully
extended the ramp should cause the platform’s front edges to be in firm contact with
the floor and the tracks to be lifted of the floor at the front end about one centimetre
• Irregularities are best noticed by rising the ramp repeatedly to it’s full up position and
then quickly pressing the down button to release the pressure. If, while the ramp is
fully extended the top of the cylinder moves more than 5 mm either towards the front
or the back of the Robot then the machine should not be used
• It is quite usual for some oil to be present around the top of the cylinder, however
with the up-button pressed and the pump running there should be no oil running
down the outside of the cylinder
• Check that the down-button permits the ramp to descend, and in addition check that
the descend adjuster permits the speed of the descend to be altered. From fully
extended to fully closed should take no less than 25 seconds with an applied load of
80 Kilogram with the ascend adjuster turned maximum counter clockwise
• 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 when going from forward to reverse direction on the pendant button the
delay before the tracks start moving in the opposite direction is no longer than one
second. Any longer time indicates sloppiness in the drive chain which should be
investigated
• Check that the platform sits down on the lower base when lowered
• Check that the castors of the dolly can move in all directions and are not jammed
Check that the cable of the winch has not been deformed
•
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.

5.2. Loading
5.2.1 The correct position of the load
• The objective is to create an optimal centre of gravity position for the loaded stairrobot
considering the ‘weight distribution’ of the load
• If the load is not placed in the correct position on the lifting
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.
• Before positioning the load on the
lifting platform the centre of gravity of
the load has to be determined
• Position the load on the platform with
the centre of gravity of the load end
forward (in positive area)
• Position the load with the centre of
gravity of the load as low as possible
to the lifting platform.
Page 15 of 28
AATA INTERNATIONAL B.V.
5.2.2. Loading procedure
• Start the procedure by securing the area for loading. Move the dolly with the stair
robot into the desired position for loading.
• Always unroll extension power cable and connect with the robot before connecting
to mains
• Reverse the Robot of the dolly, fit the loading-ramp into position at the front of the
robot
• Slot the winch into the lifting platform at the rear of the stairrobot
• Pull the winch-hawser out and connect it with the load. The load can now be
winched into position on the stairrobot, one man operating the winch and one man
guiding the load of the ramp onto the platform. While operating the winch the
lifting platform will rise until the platform has reached the same gradient as the
loading-ramp
• Connect the load secure to the lifting platform. Note: never fit any straps to the
chassis-bracket
• If the load is secured to the stairrobot the winch and loading ramp can be
removed
• Always remove the winch from the stairrobot before ascending the stairway
because it ads length to the dimensions of the stairrobot
• Turn the descent-adjuster maximum clockwise
• Lift the platform +/- 10 cm by pushing the up-button
• Push the down-button to lower the platform and turn the descent adjuster counter
clockwise until the platform starts to descent. Lower the platform
• The stairrobot can now be driven back on the dolly; use the up-button to keep the
‘platform level’ in horizontal position
Manual Stair Robot SR1750 HE
Publication: 29-07-04
• The centre of gravity of the load should
be within the positive area between the
tracks.

AATA INTERNATIONAL B.V.
Manual Stair Robot SR1750 HE
Publication: 29-07-04
5.3. Ascending
Load level
• Ideal load level is obtained
by adjusting the platform to
the gradient of the stairs or
dolly
• The objective is to maintain
a horizontal level of the
platform during operation.
• Note: do not lower the platform
over its balance point, the Stair
robot will 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.
• Move the loaded stairrobot on the dolly with the forward end towards the bottom of
the stairs
• Fit the lead on ramp between the dolly and second or third step on the stairs.
• Secure a load support strap (6 m) to the reverse end of the stairrobot. Place the strap
across the forward end of the load to be held by one of the operators.
• Both operators should move on to the stairs and make sure that no person is beneath
the stairrobot
• One operator will use the remote control button panel and drive the loaded stairrobot
up the stairs. The other will firmly hold the load support strap; this will enable him to
‘feel’ the balance of the load. He also uses it to restrain the load if necessary and
helps its forward movement at the top of the stairs
• The control operator will press the forward button to drive the stairrobot over the lead
on ramp and up the stairs. He will keep the load level by adjusting the platform
position using the up or down button.
• The up or down button can be pressed simultaneously with either forward or reverse

• The stair robot can be stopped at any stage by just releasing the buttons
• When arriving on top of the stairway; stop the stairrobot on the stairs and place the
dolly in position at the top of the stairs in front of the stairrobot. Pull the extendable
frame out of the dolly to increase stability
• Start the forward movement again
• Note: expect a change of gradient from the level of the stairs to the gradient of the
dolly
• When the stairrobot has reached the ‘point of balance’, the operator holding the load
support strap should assist in the movement by gently pulling the load support strap,
to ease the load downward. The other operator should keep the ideal load level
during this operation. The stairrobot can then be driven forward to settle onto the dolly
• Transport dolly and load to the unloading point or to the next flight of stairs to
continue upwards.
5.4. Descending
• Make sure that the stairway is secured and no person can enter the stairway.
• To descent the stairrobot down the stairway the loaded stairrobot has to be first
driven onto the dolly, as previously described for ascending
• Move the loaded stairrobot on the dolly with the downward end towards the edge of
the top of the step and stop 10 cm away.
• One operator will drive the stairrobot using the control panel while the other operator
will steady the load firmly using a load support strap.
• Press the reverse button to drive the robot from the dolly and down the stairs
• The up and down button is used to maintain ideal load level
• By reversing slowly, 5 cm at a time, and stopping at the ‘point of balance’ the control
operator will be able by pressing the up button gently alter the centre of gravity so as
to lower the reverse end tracks onto the top of the stairs.
• The dolly should be moved aside when the stairrobot is fully on the stairs.
• Drive the robot in reverse down the stairs steadying the movement throughout by
using the a load support strap
• Depending on the gradient, the stair robot will ride on the edge of two or three steps
at once. The rubber tracks pressing firmly onto the stairs
• On some stairs it may be found that occasionally two of the rubber treads ride on the
stair edge and when the third tread releases it’s grip the stairrobot will move down
suddenly about 2,5 cm until all three treads grip once more. This occurrence should
be expected by the operators and the stair robot should be driven on without a pause
• Before arriving at the bottom of the stairs the dolly and the lead on ramp should be
placed in position with the lead on ramp resting on the second or third step.
• Drive the stairrobot of the stairs and onto the dolly keeping the ideal load level by
using the up or down button
• Transport dolly and load to the unloading point or to the next flight of stairs to
continue downwards.

5.5. Unloading
• Start the procedure by securing the area for unloading. Move the dolly with the
stair robot into the desired position for unloading.
• Reverse the Robot of the dolly, fit the loading-ramp into position at the front of the
robot
• Slot the winch into the lifting platform at the rear of the stairrobot
• Pull the winch-hawser out and connect it with the load. Disconnect the load from
the lifting platform
• The load can now be lowered to floor level, one man operating the winch and one
man guiding the load of the ramp onto the floor. While lowering the load the lifting
platform will rise until the platform has reached the same gradient as the loadingramp
• If the load is on the floor the winch and loading ramp can be removed
l these techniques should be practised with a light load first
