1. If the trolley is not even (horisontal) it needs to be
calibrated, see “Calibration of the actuators” below.
2. If the trolley doesn´t move up or down. Make sure you
have voltage from the charger, see “Charging” below.
3. Lift the mattress and the white shelf. Remove the two lids
of the control box and make sure that the fuse is OK and
that there are no wires loose or any bad connections, see
wire diagram in the spare parts list.
4. Measure the batteries. They shall give at least
12,5 V each.
5. Does the handcontrol work, see “Audible sounds” below.
6. If the handcontrol is broken it needs to be changed.
The new handcontrol (without charging inlet) is plugged
directly into the controlbox as well as the charging inlet,
see separate instruction “New handcontrol” how to
update.
7. If the trolley doesn´t work at all, the circuit board may
need replacing.
8. If one of the actuators needs to be changed, see
“Changning the actuator” separate info.
9. Central foot operated brake and straight steering castors,
see separate info.
10. If the side rails or the stretcher have to be changed, see
separate info.
Trouble shooting
Charging:
1. Be sure of that the trolley is properly charged. Press the
up button on the hand control. A long and a short
audible tone sound when the battery is low and needs to
be charged. Charge over night if needed.
2. Use only the 24V battery charger delivered by TR. First
connect the battery charger to the hand control input on
the old trolleys and in the control box on later and
updated models. Then plug the battery charger to the
mains.
3. When the battery charger is properly connected, an
indicator on the battery charger shall lit yellow.
The indicator shows the charging cycles.
Yellow is charging
Green indicates that the trolly is fully charged
Normal charging time is max 8 hours when at
batteries. The trolley can never be overcharged.
4. If the indicator is not lit yellow, recheck the connections.
Measure the battery charger, it shall give 28 V.
5. If the indicator doesn´t change to lit green, test and
change the fuse (15 A) inside the control box.
6. When the charging is completed, disconnect the charger
from the mains before you disconnect the charger from
the trolley.

Audible sounds when pressing the handcontrol:
Short tone:
This tone informs that the stretcher is level when tilting and
stops. Proceed tilting by pressing once more on the
handcontrol.
A long and a short tone:
When this tone sounds the trolley needs to be charged.
A long and two short tones:
When this tone sounds the stretcher shall be calibrated to
level, see “Calibrating the actuators” below.
Calibrating the actuators:
Both the actuators runs at the same speed and need to be
calibrated when a long and two short audible tones sounds.
Use the handcontrol to calibrate the actuators.
1. Press the UP symbol and raise the stretcher about 20 cm.
2. Press the DOWN symbol until the stretcher stops in its
lowest position.
3. Press the DOWN symbol once more to make sure that
both actuators are in their lowest positions.
Two short audible tones sound when both actuators are in
their lowest position.
4. Press the DOWN symbol once more and the actuators
are now calibrated. The stretcher is level and the trolley is
calibrated and ready for use.
Note: Calibration must also be performed after each
power failure, for example after changing the batteries or
of the fuse.

To disassemble the system follow these instructions in reverse.
1. Turn the Atlas upside down.
2. Start to disassemble. When all the parts are removed follow the below points.
This instruction is explained when Atlas Jr. is placed upside down and you are standing on
the short side with the foot control right in front of you.
1. Mount the castors. The castors have small labels on
them. Red=Brake castor (11.) and Green=Straight
steering (10.). The labels on all castors must be
pointing to the right. Put two castors
with red labels on the left side and 1
castor with red label lower right corner. The last castor
with green label is then placed in the upper right corner.

4. Place the axis control (4.) in the correct position on both
  sides,butdonotxwithscrews.
5. Push in the long round castor control rod. With the link
arm (1.) and fork (14.) mounted on it. On the head end side
thesetscrewonthelinkarmmustbefacingupwardsandon
thefootendsidethesetscrewmustbefacingdownwards.
Total length of this control rod should be approx.. 161,5 cm.
6. Push in the hexagon rods through the castors, link arm
and axis control.
7. Nowtestthefunctionsofthecastorswithbrakeand
straight steering. First test the straight steering by using the
toolonthehexrod.Pushthetooldownwards.Thecastor

not able to roll.
8. If the brake function doesn’t work, then the castor control
rod is too short. So then you will have to pull out the
hexagon rods on both sides and pull out the link arm (1.)
to adjust so that the total length of the castor control rod
will be longer. Turn the link arm counterclockwise two to
three full turns. Then push in the castor control rod again
and also push the hexagon rods back in place and test
the brake function again. (The length of the control rod is
quite sensitive so this adjustment might have to be done
a couple of times to get it right.)
If the tool double clicks or gets stuck between brake function
and neutral, then the castor control rod is too long. Then do
the same procedure as above but turn the link arm clockwise
instead to get a shorter total length.
Then test again to see that everything works ok.
9. When all the castors are working ok. then use the tool to
put them in neutral again.
10. Now start working on the head end side (where the foot
control is placed). Mount the slotted end caps (3.) on
both sides as photo.
11. Push on the o-rings (7.) on both sides.
12. Push on the lever lock (2.). See photo. Note that this lever
lock must be mounted as photo so that the holes on the
 footcontrolwillt.
