IMPORTANT RECOMMENDATIONS AND GUIDELINES FOR THE COMMISSIONING
Before putting the Cargo Floor loading and unloading system into operation, follow the recommendations
provided below and check the specified checkpoints to avoid damage to the Cargo Floor system and the
vehicle. Please review the important instructions before operating the Cargo Floor moving floor system
and loading cargo into the vehicle. Likewise, before loading cargo, check the operation of the various
control switches/valves to familiarise yourself with how the system works. We strongly recommend that
you perform these checks when picking up the vehicle from the dealer so that your skilled supplier can
answer your questions and provide you with any necessary advice or guidance you may require.
Important:
Always check that the selected loading or unloading direction is actually activated and occurring!!
If the system fails to start, turn off the Cargo Floor conveyor transport system and the hydraulic
pump and follow the recommendations and guidelines provided below. Do not repeatedly try to
start the system as this may result in damage to your Cargo Floor system and/or vehicle.
After use, turn off the Cargo Floor system and hydraulic pump. Set switches to the "0" position and
the lever in neutral.
In case of doubt or uncertainty about these recommendations and guidelines, always contact your dealer
or an official workshop.
The Cargo Floor system comes standard with an user manual, but is this has not been supplied, please
contact your dealer or download it from the official Cargo Floor website: www.cargofloor.com
A) Always open the vehicle's doors before turning on the hydraulic pump. Note! Build-up of pressure
against the doors can open them with force. Also some of the cargo can fall out of the vehicle by
itself after opening the doors, therefore KEEP CLEAR AT ALL TIMES, product could fall on top of
you! Both could result in damages and/or injuries! It is always advisable to use the pneumatic door
lock, if provided.
B) 1. Check that the vehicle's (quick-detachable) couplings are properly connected to the P (Pressure
line) and the T (tank/return line). Also check that the couplings are fully tightened or slid completely
into each other.
IMPORTANT: the pressure and return line connectors may not be reversed or exchanged to
prevent dirt or water from entering the lines when connecting them!
2. Before connecting, check that the non-return valves can open easily (check: the non-return
valves should open easily when pressed with the finger, if not, potential pressure build-up in the
hydraulic lines may be preventing the system from starting).
NOTE: Incorrectly connected or unopened hydraulic couplings will cause serious damage to the
Cargo Floor system and the vehicle.
C) The vehicle (pump) must be fitted with a pressure relief valve that is set at the maximum pressure
according to the system, see the technical specs. If fitted, check that the dual-function lever
(function: tipper/Cargo Floor) is in the Cargo Floor position. Pressure may not exceed the
maximum adjusted and allowable operating pressure of the Cargo Floor moving floor system. An
incorrectly adjusted pressure relief valve can cause damage to the Cargo Floor system and the
vehicle.
D) During operation, the (hand)brake of the vehicle must always be applied. You must, however,
move the vehicle forward on time to unload it quickly in order to prevent unnecessary strain and
wear to the floor and the vehicle.
E) Use of a wireless remote control is permitted only if it is fully tested before the start of each loading
or unloading operation. Always check if the function you have selected is actually activated and
taking place. If, for example, you have accidentally pressed the load function when you actually
meant to press the unload function, irreversible damage may occur to the Cargo Floor system and
the vehicle.
F) During operation of the Cargo Floor conveyor system, all existing STOP and control knobs/levers
must be freely accessible.

G) The pressure filter element needs to be replaced at least once a year. If the couplings between the
vehicle and the Cargo Floor system are regularly removed, it is advisable to check the pressure
filter for dirt build-up and replace the pressure filter element more often, if necessary. If provided,
also check the return filter (not supplied with the Cargo Floor). Failure to replace a filter element on
time may cause damage to or malfunctions in the Cargo Floor system and the vehicle.
H) Moving parts must be shielded. Always maintain at least 10 meter [30’] distance from the Cargo
Floor system when it is in operation.
I) In the event of malfunctions/maintenance work, you may approach the Cargo Floor conveyor
system only if all equipment, including the hydraulic pump, have been shut off, and the Cargo Floor
system and the electro-hydraulic aggregate have been disconnected from the power supply and
pump.
J) Regularly check and, if necessary, tighten any loose bolts that secure the aluminium floor profiles
to the Cargo Floor system. All such checks can simply be performed inside the vehicle itself by
qualified personnel. The Cargo Floor conveyor transport system must, however, be turned on in
unloaded condition and the person performing the check must place his finger half on the floor
profile and half on the bolt. There should be no appreciable movement/space between the floor
profile and bolt. Failure to check these bolts may lead to damage to the Cargo Floor system.
During this check, a second person must also be present to switch off the Cargo Floor system.
K) Check that the minimum required amount of oil is present 150 liter [40 US gallon]. Too little oil in
the hydraulic tank will cause damage to both the pump and the Cargo Floor system.
L) Do not allow the number of strokes to exceed the maximum allowable 16 power strokes per
minute. Only a CF500 SLC Power Speed Cargo Floor system may deliver up to 23 beats per
minute. A higher number of power strokes can cause damage to the Cargo Floor moving floor
system and the vehicle.
M) Hydraulic lines, couplings and hoses with very small diameters will cause damage.
N) If the Cargo Floor moving floor system fails to start or operates incorrectly, the Cargo Floor system
and the hydraulic pump must be shut down immediately. Subsequently, check all the checkpoints
before switching the pump and the Cargo Floor system back on. To prevent the oil from
overheating, regularly check the oil temperature by CAREFULLY and CAUTIOUSLY touching the
line and or oil tank. If either is too hot to the touch, stop touching them right away. WARNING:
TOUCHING OVERHEATED OIL AND COMPONENTS CAN CAUSE BURNS!
O) The cause of failure or malfunctioning of the Cargo Floor system may also be due to other
hydraulic components that may or may not be connected to the same hydraulic circuit of the Cargo
Floor system.
P) Jamming of the floor profiles caused by the transport of abnormal loads and or the freezing of the
floor or of the product to the floor may result in damage to the Cargo Floor system and the vehicle.
Recommendation: in the event of freezing, stop the system and try to find a hall (heated area) to
allow the product to thaw.
Q) Because the electrical power supply of the Cargo Floor system is often connected to the lighting
circuit of the vehicle, it is advisable to turn on the lighting throughout the operation of the system.
R) Maintenance and repairs to the Cargo Floor system may be only performed by qualified personnel.
Use only original Cargo Floor components to ensure maximum reliability and long service life.
S) Maximum cargo weight is subject to the limits set by law and applicable regulations. Even if the
system can transport heavier loads, the law determines the maximum limit. Excessively heavy
cargo can cause damage to the Cargo Floor transport system and the vehicle.
T) Check that the correct type and quality of hydraulic oil is used. The use of incorrect oil type may
cause damage to the Cargo Floor system and the pump.
U) Check the vehicle for correct voltage. Make sure there are no open electrical connections. A faulty
electrical system can cause damage to the Cargo Floor conveyor system and the vehicle.
V) Check that the bulkhead, if present, is functioning smoothly and properly. A properly functioning
bulkhead ensures that the product is unloaded in a clean and quick fashion. A malfunctioning
bulkhead may extend the unloading time and cause damage to the vehicle.
W) Use of the Cargo Floor system by unqualified personnel can cause damage to the Cargo Floor
system and the vehicle.
X) Excessively high oil temperatures will cause damage to the Cargo Floor system and other
hydraulic components, such as the pump.

Y) It is at all times advisable to stop the Cargo Floor system when all the piston rods are retracted.
This is usually the case when the floor profiles are positioned towards the unloading end (vehicle
doors). Unretracted piston rods may cause damage to the Cargo Floor system.
Z) To prevent damage to the floor profiles, exercise caution and limit the dump height as much as
possible. The transport of unauthorised goods, such as aggressive, corrosive, hot, hard, sharp and
viscous materials may cause damage to the Cargo Floor system and the vehicle. Avoid loading
and unloading sharp objects. Loads that are softer than the hardness of the floor profiles will
extend the service life of your system; if in doubt, use a protective cloth or consult your dealer.
AA) Forklift trafficable. In principle, the floors are completely trafficable and can be driven over by
forklifts, but always consult your dealer for advice on the maximum loads allowed on your vehicle.
Overloading will cause damage to the Cargo Floor moving floor system and the vehicle.
BB) Always return emergency control(s) to their original non-activated position after use.
CC) During the operation of the system, test the temperature of the oil by touching the side of the tank.
If the oil is so hot that you cannot continue to touch the tank, switch off the pump to allow the oil to
cool off and determine what is causing the overheating. Stop loading or unloading if the oil is too
hot, as this will irreversibly cause damage to the Cargo Floor system and the other hydraulic
components.
WARNING: TOUCHING OVERHEATED OIL AND COMPONENTS CAN CAUSE BURNS AND
INJURIES!
DD) During loading and unloading operations, the load should be spread to give an even weight
distribution over the floor area, otherwise the load may stall. Tip: when transporting pallets, place
softwood boards of 300 x 18 x 2350 mm. [12” x 0.75” x 92.5”] to distribute the pressure more
evenly.
EE) The constant pressing of the load against the head board or the doors can lead to extra wear of
the complete system. Also the construction can be damaged. Please consult you supplier about
the optimizing possibilities or in order to prevent problems occurring.
FF) The user/operator/driver that is operating the Cargo Floor system is compelled to remain a safe
distance from the Cargo Floor system at all times, from the time of switching on the hydraulic pump
until turning it off. He should ensure that no dangerous situations can occur. When the process
malfunctions or if other people are present he should shut down the Cargo Floor system, or
hydraulic pump, immediately.
GG) No unauthorized alterations/modifications/changes/adjustments may be made to any part of the
Cargo Floor drive unit and system.

Follow the instructions carefully
With this instruction it is possible to measure the maximum pressure of an empty trailer.
The Cargo Floor moving floor systems are extensively tested and adjusted on the right pressure setting
when the system is supplied to the trailer builder.
In some cases it is necessary to check the maximum pressure. This is required when the system needs
more force to operate then is available. Check our internet site, www.cargofloor.com, after sales, to find
out what kind of system you have. The various types of systems have different maximum pressure
settings. You could also check the identification plate of the system to see what the maximum pressure
is of the specific system.
To document the information fully we advise you to download the hydraulic data sheet from our internet
site www.cargofloor.com, after sales and fill it in as complete as possible. The position of both
measurement points, M1 and M2, are also indicated. Connect both manometers before start taking the
measurements.
This instruction is meant for the standard system types, eg. the CF300, CF400, CF500 SL, CF500 SL2
and the CF500 SLC. This instruction applies to all these systems.

1. Switch on the pump and start the system. Let the
command lip from group 1 move away as far as possible
and stop the system at that moment.
2. Switch off the pump. Take away the bolt (or pin) in the
command lip from group 1.
3. You will be able to pull the threaded rod down and slide the
spring and washers of the threaded rod in the direction of
the head board of the trailer.
4. Pull the threaded rod by hand in the direction of the
headboard of the trailer.
5. Switch the pump on and start the system, group 1 will
move in the direction of the rear doors of the trailer.
6. Group 1 will not be able to switch the threaded rod on the
end of its stroke. The system will activate the pressure
circulation valve and the maximum pressure can be read
on the manometer attached to measurement point M1 on
the control valve. After reading the maximum pressure
stop the system immediately and switch off the pump.
7. The switching of the threaded rod must be restored after
this check. Push by hand the threaded rod in the direction
of the doors of the trailer. Switch on the pump and start
the system. Group 1 will move in the direction of the
headboard of the trailer. When the command lip of group 1
is as far away as possible, stop the system and switch
off the pump.
8. The washers and steel spring can be put back on the
threaded rod after you pull the threaded rod down.
9. Put the bolt (or pin) back in the command lip of group 1.

1. The measured pressure on measurement point M1 is correct
The maximum pressure will not cause any malfunctions. However if you have problems related to lack
of pressure (= lack of force) we advise you to contact Cargo Floor for further instructions.
2. The measured pressure on measurement point M1 is too low
The next steps are needed to get the full information.
1. Check the pressure of the pulling vehicle. If the pressure is lower then the required pressure,
adjust it to the right pressure.
2. Check if a tipper valve is on the truck. If it is turned to the wrong setting turn it to the right setting.
3. Check if there is other hydraulic equipment on the truck or trailer that could influence the pressure
that is available for the system. If there is equipment present, bypass it and check the max.
pressure again.
4. If everything is OK with regards to the truck and the trailer, you should check the maximum relief
valve of the Cargo Floor transport system and check for pollution. For this remove the complete
maximum relief valve.
Do never ever take the valve apart and never ever adjust the setting of the
maximum relief valve without contacting Cargo Floor beforehand. Warranty will no
longer be valid if the settings of the maximum relief valve have been altered and
unauthorized changes could also damage the system/trailer and create dangerous
situations.
Contact Cargo Floor for further assistance from the after sales department.
3. The measured pressure on measurement point M1 is lower than the pressure measured on
measuring point M2
The pressure and return pipe from the pump are connected wrong (reversed). This means that the
pressure pipe is connected to the return side (T) and the return side has been connected to the
pressure side (P).
Switch off the pump immediately and do not switch it back on.
The filter element will be, as a result of this, damaged. Before you turn on the pump again it will need
to be checked and replaced. The pipes also need to be connected the right way.
Check after the measuring if the Cargo Floor moving floor system fully functions correctly before it leaves
the workshop.
When you have any doubts regarding a malfunction or the results of your measurements, please contact
the Cargo Floor after sales department. Make sure that you have the system serial number at hand
when you call because it will be asked.
