Before Use: Preparing the Robot Trolley
Checking the status
1. Unpack the Robot Trolley and check that the Robot Trolley is clean and not broken
2. Make sure the Robot Trolley battery is charged according to instructions
Mounting the suspension fitting –standard bracket2
REGIONAL VARIANTS
Some countries and makes of caravan may require a special bracket version. Please inquire with your dealer.
If there is a plastic cover over the side member system on the caravan, it can be helpful to remove it while mounting the
suspension fitting.
1. When mounting the suspension fitting from the Robot Trolley onto the caravan, start by gliding the two mounting
tubes, A1 and A2, together, and then placing them up inside the side members.
2. Next, loosely screw on the mounting bracket to the inner mounting tube, and screw the female piece to the
mounting bracket. If there are larger distances between side members, place the extension tube inside the inner
mounting tube.
The illustration below shows the assembled suspension fitting mounted on the side members:
3. Slide the entire suspension fitting as far back on the side members as possible to put maximum weight on the
Robot Trolley. Do not push the suspension fitting so far back that mounting and removing the Robot Trolley
becomes difficult.
The following illustration shows the optimal placement of the suspension fitting on the caravan:
4. Push the Outer and Inner Mounting Tube as far from each other as possible, towards the sides of the side
members. Tighten the left and right brackets so that the bent undersides of these are positioned precisely against
the outer side of the side members. Make sure that the bolts are tightened to the maximum extent.
(If the caravan’s bearers are extremely narrow, and the mounting tubes cannot be pressed far enough together
upon mounting, you can use a hacksaw to shorten mounting tube A2. There must be minimum 10-15 cm inner
overlap of the Outer and Inner mounting tubes.)
5. Once the suspension fitting is adjusted and fastened to the side members, tighten the clamp bolt into the side of
the inner mounting tube.

Mounting of Robot Trolley
1. When mounting the Robot Trolley on the suspension fitting, adjust the height of the suspension fitting using the
nose/jockey wheel.
2. The suspension fitting mounted on the Robot Trolley fits into a slit on the underside of the mounting fitting on the
left side (seen from the ball catch) and can be pushed into place in this slot.
3. After pushing the Robot Trolley into the slot in the mounting fitting, attach the factory-provided cotter ring, which
locks the Robot Trolley in place.
4. After attaching the cotter ring to the Robot Trolley, raise the support wheel to its highest position, and release the
hand brake. This shifts the weight of the caravan onto the Robot Trolley. You are now ready to tow your caravan.

members of the caravan:

Using the Robot Trolley
SOME ADVICE ON SAFETY AND OPERATION BEFORE STARTING
1. Familiarize yourself with the operating manual, and practice maneuvering the caravan on a flat surface before
attempting to maneuver it on sloping surfaces. We recommend testing your Robot Trolley at home –also
without a caravan –so you can try out the different maneuvering options.
2. Load: The Robot Trolley is designed for moving caravans weighing up to approx. 4500 kg (Model RT4500) and
2500 kg (Model RT2500RS). In order for Robot Trolley to function optimally, the ball weight must be at least
75-85 kg. This ball weight creates about 120-150 kg of pressure on the Robot Trolley. Too little weight on the
Robot Trolley may result in poor gripping and poor towing results. Greatest pressure is achieved by mounting
the Robot Trolley as far back on the side members as possible.
3. Level surfaces: To ensure optimal transfer of the Robot Trolley’s power to the surface it is to operate on, the
Robot Trolley must move in the direction of the antenna, i.e. forward. (Except on sloping surfaces, see below).
4. Sloping surfaces: Operating the Robot Trolley on sloping surfaces may shift and decrease the pressure on the
Robot Trolley, resulting in poor contact with the terrain.
oWhen using your Camper-Trolley to move your caravan or trailer UP a slope or edge, the CT must PUSH
the caravan up the slope –if necessary, one wheel at a time. Optionally, use a ramp.
oWhen moving your caravan DOWN a slope the CT must LEAD the caravan DOWN the slope.
ATTENTION: If going downhill, it is very important that the Robot Trolley is turned 180 degrees, so that it
is moving in reverse, down the hill, i.e. with the antenna opposite the maneuvering direction and facing
the caravan. This is important, as the Robot Trolley might otherwise tip over forward.
Special precaution
5. Be aware that if towing down very steep inclines or on wet, oily surfaces, it may be necessary to use the hand
brake on your caravan during operation if the Robot Trolley is unable to hold the caravan or the caterpillar
tracks cannot adequately grip the surface.

Activating and Pairing the Robot Trolley with the remote control
The Robot Trolley comes pre-paired with the remote control.
-Turn on the Robot Trolley by simply pressing the Start/Stop button for maximum 1-2 seconds.
-Turn on the remote control by pushing the forward button () once.
-The Robot Trolley is now ready to use.
IMPORTANT
Re-pairing the Robot Trolley
1. Turn on the Remote Control by pushing the Forward button () once. The green light on the Remote Control will
turn on.
2. Turn on the Robot Trolley by clicking the Start/Stop button. The green light on the Robot Trolley will turn on.
3. Now simultaneously press and hold the Turn Right button (→) on the Remote Control and press and hold the
Start/Stop button on the Robot Trolley, both LED lights start to blink for 8 seconds, after which the LED lights will
light constantly. Now the Robot Trolley and Remote Control have been re-paired and are ready to use. If this
pairing procedure is unsuccessful, the Remote Control will turn off automatically in around 15 seconds, and the
user needs to redo the procedure from step 1.
The start/stop button and operating status
indicator are located on the front of the Robot
Trolley
(The diode lighting can be difficult to see in
strong sunlight):
The maneuvering buttons on the remote control (RT4500 model):
Forward: (  );Turn right: ( → )
Backward: (  );Turn left: (  )
The battery indicator shows the Robot Trolley’s remaining battery
status. If the capacity is too low, the CT may not respond correctly.
If the indicator itself weakens, the remote control battery needs to be
replaced, otherwise the CT may not respond correctly.
Maneuvering the Robot Trolley
The Robot Trolley logo on the remote control must always point toward the trolley.
Use both hands on the remote control, and hold it horizontally during use.
-Forward: To move forward, in the same direction as the antenna, hold down forward button ().
-Backward: To move backward/reverse, hold down the back button ().
-Turn: To turn, hold down the forward () or backward () button while at the same time holding down one of the
turn buttons of the remote control to turn right (→) or left (). The Robot Trolley will only turn if you first hold
the forward or backward button, followed by a turn button.
-Stop: To stop the Robot Trolley from moving, simply release the forward or backward button.

After Use: Detaching, Cleaning, Storing, and Maintenance
Detaching the Robot Trolley
Never leave the Robot Trolley mounted to the caravan while towing the caravan behind a car.
It is important that you always detach the Robot Trolley after use and place it in the storage box/bag together with the
remote control.
When you have finished towing the caravan and you want to disconnect the Robot Trolley, pull the parking brake and
adjust the nose/jockey wheel so that the caravan is slightly elevated. This takes the weight off the Robot Trolley.
Remove the cotter ring and use the remote control to move the Robot Trolley out of the lock fitting (or pull it out
manually).
Cleaning
If you have used the Robot Trolley in wet or dirty conditions, you can clean it in the following manner:
Remove pebbles, clay, grass and the like from the belts. Then give it a gentle cleaning using a small amount of clean water
and a brush or cloth. Do not use soap or cleansing agents or a high-pressure cleaner.
Storage
Put the Robot Trolley in the transport box/bag delivered from the factory. If the storage box/bag should become damaged,
discard it. A new plastic storage box/bag may be obtained from your Robot Trolley distributor.
Store the Robot Trolley in dry, frost-free conditions.
Do not store the Robot Trolley in direct sunlight or at high temperatures. High temperatures may drain the battery quickly.
Maintenance
The Robot Trolley should be operated at least every second month in order to keep the battery healthy.
If the Robot Trolley goes unused for more than two months, it is highly recommended that you operate the Robot Trolley
for a short while and then charge the battery until the LED on the charger turns green, in order to maintain maximum
battery life and performance.
