IMPORTANT RECOMMENDATIONS AND GUIDELINES

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 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 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 operating manual, but is this has not been supplied,
please contact your dealer or download it from the official Cargo Floor website: www.cargofloor.com,
download.

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 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 system, all existing STOP and control knobs/levers must be

freely accessible.

Version 01 / July 10th, 2017

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 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 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 system and the
vehicle.

M) Hydraulic lines, couplings and hoses with very small diameters will cause damage.
N) If the Cargo 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 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 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.

Version 01 / July 10th, 2017

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 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!
Option: your Cargo Floor system could be equipped with an oil temperature safety switch which will
switch off the system automatically when it starts to overheat.

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 your 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.

2. Circulate the oil for a few minutes to preheat it and lower its viscosity.

HYDRAULIC START-UP CHECK LIST FOR THE CARGO FLOOR SYSTEM

Before starting your new Cargo Floor (un)loader, a quick start-up check should be made

1. Hydraulic: is your entire system plumbed to the plumbing diagram?

2. *Pump: Will it pump the advised flow at the maximum pressure according to the system?

3. *Relief Valve: is it set at the maximum pressure according to the system?

4. Hydraulic reservoir: Is it big enough and filled?

5. Power Take Off: Is the P.T.O. engaged?

6. Hoses: Is the pressure line on the trailer attached to the pressure line on the tractor and the return

line on the trailer attached to the return line on the tractor?

7. Quick Disconnects: are these suitable and connected the right way?

8. Controls Cargo Floor: Operation handle unload (1) - 0 - load (2) in position 0?

*If the information about your pump and relief valve is not known, a pressure/flow check will help
determine this information. Be sure that your entire wet kit system meets the requirements of the
hydraulic wet kit specifications in this manual.

MAINTENANCE INSTRUCTIONS

When works require turning on the floor you should take care of that the floor can be shut down
immediately at any time. Places where clamping/clasping of body parts is possible may not be
approached when the system is moving.
For more detailed explanation of the execution of the works we would like to refer you to our website:

https://www.cargofloor.com/en/site/en_garantieformulier.

Check for the end user / owner after receipt of the new Cargo Floor trailer
Check a couple of days after receipt of the new trailer and / or after 10 loads / unloads and after one
month the connection between the aluminium floor profiles and the Cargo Floor system. You do this by
placing your finger half on the screw and half on the floor profile when the floor is operating.
Important: if you feel a difference in movement between the screw and the floor profile it means the floor
profile is not fastened enough. The screw connection of the whole profile group this concerns needs to
be renewed with new screws in accordance to the fastenings guidelines mentioned in the assembly
instructions (see www.cargofloor.com, downloads). Also the countersunk hole needs to be cleaned
properly. Do not check the screw connections with the help of an Allen key and do not simply just tighten
the screws, the Loctite connection will be broken.
Specifications of the screws:
M12 x 30 countersunk screws with hexagon socket, class 10.9, galvanized. DIN 7991 (dacromet). The
torque is 100 – 140 Nm [72 – 105 lbf.ft.]

Regular checks and preventive maintenance
To ensure that your Cargo Floor system operates reliably and has a long life, it is important that you
regularly perform careful checks on the following aspects:

- Replace the filter element every year, or more often if needed

- Change the oil every 2 years, or more frequently if required;

- The level of oil in the tank. See for oil levels and the oil specifications the wet kit information

- Floor profiles: are they still fixed, replace screws if necessary!

- Check the guide blocks for the 3 piston rods for wear

- Check the coupling nuts and couplings of all hydraulic components, and adjust if necessary!

- Oil tank: by taking the lid off the tank, you can remove any remains (condensation, dirt etc.) from the

bottom.

- Return-/pressure filter: by removing the filter lid/chamber you can check the filter element, or after

about one year replace it.

- Check the seal between the two fixated floor profiles and the moving profiles. If a margin exists in-

between, then adjust the fixated floor profiles, in order for the sealing to be optimal and leakage via

the side walls is prevented.
This is all necessary to avoid internal wear (of the pump/cylinders etc., for example).
New filter parts are available at your system builder. For the right type we refer you to our “exploded

views” which you can find on our website: www.cargofloor.com, downloads.
We want to emphasize that the minimal costs of replacing dirty parts or oil do not match the costs and

discomfort that can arise.

ADJUSTMENT OF THE THREADED ROD OF THE CONTROL VALVE

Front side trailer Rear side trailer

All Cargo Floor systems have the threaded rod set and are fully tested. You therefore do not need to
adjust the threaded rod, but in certain circumstances (f.e. certain repairs) it may be necessary to check

or adjust the setting of the threaded rod. If switching spontaneously doesn’t go normally anymore, then

please make a good assessment first why this has happened.
Attention:

The pump and electrical installation must always be switched-off when working on the system; in
addition, the hoses and/or pipelines between the pump and the Cargo Floor should also be
disconnected.
If not the risk of entrapment arises!!!

Necessary tools:
2x spanner 17;
High viscosity oil;
Copper grease;
Steel brush.

Check that the threaded rod (1) is fastened securely to the switching valve, with pressing and pulling the
stroke is exactly 12 mm. [0.5”].
If not, then screw the threaded rod (1) as far as possible into the plunger and secure this with the contra

nut (2) (spanner size 17). Loosen nuts (3 and 4, spanner size 17) and move these about 3 cm [1.25”] in

the direction of the rear of the trailer.
Now switch the pump on while you are at a safe distance. The system will start to move and stops
automatically at the point where the command lip (7) no longer operates the switching valve, because
the spring (8) is no longer pushed. Switch off the pump immediately.
Now push the threaded rod (1) in the direction of the rear of the trailer until the spacer ring (9) touches
the control valve.
Tighten nuts (3 and 4) so far in the direction of the front side of the trailer that the spring is fully pushed
in, and secure them by tightening them against one another. Repeat this procedure for the other side
(nuts 5 and 6) by doing everything in opposite directions.

N.B. It is worthwhile spreading some copper grease on the threaded rod (1).

FUNCTION OF B-CONTROL SWITCHES

CF 4 SWITCH (MAIN CONTROL)

The standard supplied remote control CF4, with 10 meter [30’] of cable, is used for the day-to-day control
of the system. After you have manually put the handle in the loading / unloading function, the moving floor
system can turned on / off by using the electrical switch.
The CF4 switch has the following functions:

The CF4 switch has a plug connector, which can be inserted into the connector of the CF3 switch and
screwed tight.

TO DISCONNECT THIS, THE DUCT MUST BE UNSCREWED, AFTER WHICH THE PLUG CAN BE
PULLED OUT. NORMALLY, THIS PLUG SHOULD ALWAYS BE CONNECTED TO THE
CONNECTOR.

CF3 SWITCH

The CF3 switch is the permanent switch which is mounted in the control box and has 3 switch positions
with the following functions:

In the interest of safety this switch is fitted with an automatic spring-back for position I and II, so that it
always returns to “0” position. This is necessary to prevent conflict situations arising when using the CF4
remote control.
Mounted below the CF3 switch, is a connector to which the CF4 switch or the RX RECEIVER can be
connected without the need for any adjustments. Normally, the CF3 switch should only be used if the
CF4 switch is defective.
If, after the initial assembly, the switch does not work it is probably because the connections for the +
(brown) and the – (blue) have been swapped around. The supply cable contains a blocking diode which
prevents damages arising from the + and - from being connected in reverse.
A 2 Amp fuse has been mounted in the CF3 switch. Never mount a fuse over 3A, this can cause damage
to the electrical installation.

When turned left or right, it will start the floor and when

released it will automatically return to the 0 position

stable wireless connection and a low battery (power) use. The
transmitter has a rechargeable battery that can be charged using
the micro-USB socket 6. When fully charged the stand by time will
be about 15-30 days. The transmitter has button lighting which will
automatically switch on when the light starts to fade (sensor 3).
When using the buttons, a bleep can be heard.
Do not put the transmitter in your pocket in order to avoid unwanted
operation of the system and battery drain.

Switching the transmitter on or off
Turn the transmitter on by pressing button A for 2 seconds. Led 1,
2, 4 and 5 will light up briefly. Led 4 will start to blink if there is a
connection between the remote control and the app receiver. The
transmitter will automatically switch off after 45 minutes. The
transmitter can be turned off by hand by pressing button C (stop) for
5 seconds.

Loading and unloading with the transmitter Button A (loading) By pressing this button, the system will turn on, led 1 will light up, by releasing it

the system will stop, led 1 will turn off.

Button B (unloading) By pressing this button, the system will turn on, led 2 will light up

MANUAL OVERRIDE

In the event of a malfunction in the electrical system the electric valve can still be operated by activating
the manual control fitted for that purpose.

MAKE SURE THAT THE DOORS ARE OPEN!
When using this manual override you must always ensure that it switched back to the original,

NON-ACTIVATED condition after use.
Activation of the manual override: ON

Remove the yellow security clip and turn in (clockwise) the red button on top of the on/off GS02 solenoid
till the stop.

Deactivation of the manual override: ON

Turn out (counter clockwise) the red button on top of the GS02 solenoid until the click and place back the
yellow security clip. The system switch “off”.

Activation of the manual override control loading (floor will only be able to load):

Screw the black cap off (pay attention to the O ring).
Turn out (counter clockwise) the screw under the cap of the load / unload G02 till the stop.

Deactivation of the manual override loading:

Turn in (clockwise) the screw under the cap of the load / unload G02 till the stop.
Screw the black cap back on (pay attention to mounting the O ring).

CHOKE

If the E-controlled Cargo Floor system will be operated by different types of pumps or a pump with a low
oil flow, it could be that you have to pay attention to mount another type of choke.

Choke

There is a standard 6,5 mm [0.26”] choke mounted as standard in the PB channel of the E control valve.

This allows the E control valve to function correctly. This standard choke is suitable for an oil flow level of
60 to 110 litres per minute [16 to 29 gpm]. The function of the control valve can be affected by a
deviation from this oil flow level. The oil flow diagram shows which level of oil flow is required by which
opening. Adjustment of this is possible by simply changing the diameter of the choke.
Known consequences of a wrong choke diameter are:

- Oil flow too low: load/unload operational plunger is not switching, system gets pressure less;

- Oil flow too high: noise in system, high heat dissipation and capacity loss.
Flow independent choke

As an option a flow independent choke can be supplied (variable choke article number 7370106). The
standard mounted choke can simply be changed with these. You remove the socket plug out of channel
PB (Allen key 12 mm). After this you screw the choke out of the channel with Allen key 12 mm. Screw
the new variable choke in the channel and fasten these by hand (about 15 Nm [11 lbf/ft.]). Screw the
socket plug back into channel PB (Allen key 12 mm) and fasten these by hand (about 15 Nm [11 lbf.ft]).
Let the floor run (loading and unloading) in order to check if everything is functioning well and no leakage
occur. The variable choke has a flow range of 20-120 ltr./min [5-31 gpm] ±10% using a VG32 and is
suitable for a maximal work pressure of 225 bar [3300 psi].

Important

Connecting pressure and return wrongly will cause a malfunction, and damage to, the system.

B-control
Another possibility to be independent from a variable oil flow is using a B-control. With this the
loading/unloading direction is determined by a handle.
