1. INTRODUCTION
1.1 PURPOSE AND FUNCTION OF THE TRAILER
The trailer is intended to be used to transport both bulk goods and individual items. The
trailer consists of a chassis with a single axle, tandem axle or tridem axle on which a
cargo bed is fitted. For types COBALT HB and the INDIGO HT and LT the cargo bed
can be tipped backwards by means of a hydraulic pump and cylinder. For type
COBALT HM and COBALT+, the cargo bed can be tipped to the left, right or
backwards, as desired by the user, by means of a hydraulic pump and cylinder.
1.2 MODELS AND ACCESSORIES
The (technical) specifications of all the HAPERT models and types are available in the
Media section of WWW.HAPERT.COM.
Wagenbouw HAPERT 10
2. SAFETY
2.1 INTRODUCTION
The trailer has been designed in such a way so that it is safe to use and maintain. This
applies to the uses, circumstances and guidelines described in this documentation.
Everybody who works with or on the trailer must, therefore, read this documentation
and follow the instructions it contains.
In the case of professional use, it is the employer’s responsibility to ensure that the user
is familiar with the instructions and that they are observed.
Additional safety measures may apply in the company or country in which the trailer is
used. These measures mainly relate to the working conditions. This documentation
does not describe how these measures must be complied with. It does, however,
contain all the information you will need about the trailer. If you have any doubts, ask a
relevant government official or your safety officer.
In this documentation, a distinction is made between normal use (see chapter 3:
Operating Instructions) and other work (see chapter 4) carried out on the trailer. The
reason for this is that service personnel have to meet different requirements than the
operator, particularly with regard to safety.
Simple maintenance work described in the operating instructions can be carried out by
the operators.
Work that is not described in the operating instructions may only be carried out by
people who are qualified to do so. The accessories that are supplied with the trailer to
restrict access to specific sections or functions (such as the key to the main switch) may
not be stored on or near the trailer. These accessories may only be entrusted to people
with the required qualifications.
Wagenbouw HAPERT 11
2.2 SAFETY REGULATIONS
Ensure unauthorised people, such as children, cannot operate the tipping
system. The key must be removed from the main switch when the trailer is left
unsupervised.
People may only use the trailer if they have read and understood the operating
instructions.
The tipping system may only be operated when the trailer is stationary, the brake
has been applied and the trailer is connected to a towing vehicle.
Do not climb on the trailer when the tipping system is being used.
Do not climb on the trailer if it is not connected to a vehicle.
When tipping the load off the trailer, make sure nobody is in the area where the
load is to be tipped.
Safety devices may not be removed or put out of operation.
Keep the workplace neat and tidy, and free of obstacles.
Make sure the surroundings are adequately illuminated.
Be aware of the risk of becoming trapped between the cargo bed and the frame
or the front, side and rear flaps.
A trailer must be on a stable surface (not to sink into gravel or sand) during
tipping. Trailer may fall.
Using the tipping system on an incline is dangerous. Trailer may fall.
When using tipping system always use the mounted supports. (For instructions,
see Section 3.2.2)
Do not exceed the maximum permitted load (see name/type plate).
Do not exceed the maximum permitted ball thrust (see name/type plate).
Do not exceed the maximum load of the tie rings
Only use the remote control after reading the operating instructions (see 3.1.2).
2.3 UNAUTHORISED USE
The trailer is especially not suitable for:
Transporting people or animals.
Using the tipping system to unload individual items.
Lifting people or goods.

3.1.3 CAR2TRAILER AUTOMATIC RECHARGING SYSTEM (OPTIONAL)
The purpose of the automatic recharging system is to supply the correct charging
voltage to the electrically powered tipping system. The system is connected to the
standard lighting cable using a two-pole adapter. The 13-pole connection with the
towing vehicle ensures that the Car2Trailer booster/charger provides the battery system
in the trailer with the correct charging voltage while driving. An acoustic signal is given if
the voltage is too low when using the electric tipping system. See the Media section at
WWW.HAPERT.COM for the installation manual circuit diagram.
Attention!
The Car2Trailer recharging system may only be connected by
competent service personnel who are familiar with the regulations
for working with high-voltage batteries. Always read the installation
manual. Incorrectly connecting the battery (e.g. reversing the plus
and minus terminals) or using the wrong type of connectors can
result in serious damage to the system, for which the manufacturer
cannot be held liable. Make sure the cables are firmly attached.
Always use fuses.
Figure 4.
Wagenbouw HAPERT 21
3.2 USING THE TRAILER
3.2.1 CONNECTING AND DISCONNECTING THE TRAILER
Figure 5.
Connecting:
Open the coupling housing by pressing the locking button on the handle H and
moving the handle upwards. Place the opened coupling on the ball of the towing
vehicle’s tow bar and release the handle. The handle should automatically slide back
to the starting position. The coupling is automatically closed and locked in place.
Make sure the coupling is in the right position >>+<< (see figure 5). The tow ball
must not be visible when the trailer is connected. Fasten the safety cable (see figure
11) and insert the plug in the towing vehicle. Raise the support wheel and secure it in
position parallel to the direction of travel (the support wheel must not impede the
movement of the brake rod).
Always check whether the lights work before driving.
Disconnecting:
Lower the support wheel. Disconnect the safety cable and the plug. Open the
coupling housing by pressing the locking button on the handle H and moving the
handle upwards. Lift the coupling off the towing vehicle’s tow bar. Pay particular
attention when disconnecting on an incline (once the towing vehicle is stationary,
apply the handbrake or use the wheel blocker, if fitted)
Only drive in the >>+<< range
3.2.2 LOADING THE TRAILER
Maximum load
The maximum load must not be exceeded. The maximum load is equal to the unladen
weight of the trailer plus the load capacity.
Maximum load: Unladen weight + load capacity
Wagenbouw HAPERT 22
Unladen weight: The weight of the trailer when ready to be used, i.e. with spare
parts and tools that are normally included, but without a load.
Load capacity: The maximum permitted load weight.
Weight distribution:
To ensure the brakes work properly and to have good road handling, the centre of
gravity must be as close as possible to the axle.
Heavy objects must be placed as much as possible above the axle.
Lighter objects should be distributed evenly across the cargo bed.
The load should be divided over the right-hand and left-hand halves of the trailer as
evenly as possible.
Avoid point loads.
The load must always be properly secured. Each country has its own regulations.
Make sure the trailer meets the applicable requirements.
When loading and unloading the trailer, it must always be connected to the towing
vehicle.
Figure 6
Maximum support wheel load:
The maximum static load for a sliding support wheel is 150 kg. The maximum static
load for a foldable support wheel is 250 kg. The maximum load must not be exceeded.
Attention!
Wagenbouw HAPERT 23
The trailer has been designed, constructed and tested for the loads
shown in the accompanying documents and on the type
plate/construction plate attached to the front of the trailer. Overloading
the trailer can result in permanent damage, for which the manufacturer
accepts no liability.
Tying down/securing the load:
The load must always be tied down and secured properly on the trailer using binders
that are suitable for this specific purpose
The tie rings, which are fitted as standard and are TÜV-certified according to quality
mark DIN EN 75410-1, must be used to secure a load.
Figure 7
For tying down the load, only use reliable ropes that are specifically designed for this
purpose and that comply with standard EN 12195-2.
The maximum load that the tie rings fitted on the sides of the trailer (see figure 7) can
take is 1,000 kg (daN)
Supports
Supports fitted under the chassis can be extended when loading the trailer.
How the supports work: After releasing the locking pin, the supports can be rotated
90°
Rotatable by 90˚ downwards and re-secured in position with the locking pin.
Using the handle supplied with the trailer, the support should
be lowered until it is approx. 5 cm above ground level when
the trailer is empty (see figure 8).
The 5 cm gap is needed to compensate for the spring of the axles. If the supports are
lowered completely, they will take the entire weight of the load and can become
damaged. On soft ground, suitable plate material has to be laid under the supports.
Before driving off, the supports have to be secured in their top position and, if
necessary, rotated 90° so that they lay parallel to the chassis (see figure 9).
Wagenbouw HAPERT 24
Figure 8
Figure 9
Ball thrust:
The ball thrust is one of the most important criteria for the road handling of the trailer
and, therefore, the entire vehicle combination.
The maximum permitted ball thrust (see the specifications of your tow bar or vehicle
and the type plate on your trailer) may not be exceeded. The ball thrust can be
increased or reduced by moving the load further forwards or backwards, respectively.
The optimal ball thrust is close to the maximum ball thrust. A negative ball thrust (i.e. an
upwards force applied to the tow bar) is strictly forbidden.
Carelessly loading the trailer may result in a risk of slipping or swerving. Adjust your
speed to the condition of the road surface and the load. This is particularly important in
corners.
Make sure the wheels do not wobble and the tyres are balanced.
Coupling height (with regard to the towing vehicle):
Another important element which influences the vehicle combination’s road handling
(particularly for tandem trailers) is the height of the coupling. The trailer’s coupling
height and that of the towing vehicle must not differ by too much. The vehicle
combination’s road handling is influenced by the difference in coupling height. A
dangerous situation may arise if the towing vehicle’s coupling height is considerably
lower than that of the trailer, because this results in a negative ball thrust.
Wagenbouw HAPERT 25
Relationship between load, tyre pressure, ball thrust and coupling height:
Poor road handling is unavoidable if a trailer creates a negative ball thrust because it is
poorly loaded and if it is connected to a towing vehicle with a lower coupling height. If
this is combined with a tyre pressure which is too low (see 5.1.1), then a dangerous
situation may arise. For that reason, all the warnings given above must be observed.
3.2.3 BEFORE PULLING AWAY
Raise the support wheel and secure it in position. The support wheel must always
point in the direction of travel (the support wheel must not impede the movement of
the brake rod).
Check the coupling. The coupling housing must completely enclose the ball and
must be secured. Make sure the coupling is in the right position >>+<< (see figure 5).
Attach the safety cable to the towing vehicle (see figure 11).
Safety cable
Figure 11
Insert the lighting plug.
Regularly check the tyre pressure (see table 5.1).
Make sure the load is evenly distributed and properly secured.
Check the lights: indicators, rear lights, brake lights (the load must never obscure the
view of the lights).
Before driving off, make sure any wheel blockers have been removed and that the
handbrake on a braked trailer has been released.
Check whether the cargo bed is secured to the chassis (only for type INDIGO HT
and LT).
Check whether all the locking pins are fitted and secured in place (only for type
COBALT HM and COBALT+).
Make sure the supports are secured in their top position and, if necessary, rotated
90° so that they lay parallel to the chassis (see figure 9).
The trailer has an auto-reversing mechanism. This means that if you reverse, the
overrun brake does not have to be blocked.
Wagenbouw HAPERT 26
3.2.4 TIPPING THE TRAILER
Find out whether the tipping trailer has a hand pump, an electric pump (possibly with a
battery) or both.
Warning!
Only turn on the hydraulic system when you have made
absolutely sure that nobody is in the danger zones around
the trailer. Attention:
Make sure nobody is in the location where the load is to
be tipped.
Make sure nobody is on the trailer.
Pay attention to the risk of becoming trapped between the
cargo bed and the chassis.
Warning!
Do not use the tipping system on a steep incline.
1. Only use the tipping system when the trailer is stationary and connected to the
towing vehicle.
Make sure the trailer’s handbrake has been applied.
2. Lower the support wheel.
3. Make sure the load is no longer secured.
4. To tip backwards:
- Unlock the two locking pins on the two front corners of the trailer (only for type
COBALT HM and COBALT+).
- Unlock the rear flap.
To tip to the left (only for type COBALT HM and COBALT+):
- Fit the two locking pins to the two left-hand corners of the trailer.
- Unlock the left-hand flap.
To tip to the right (only for type COBALT HM and COBALT+):
- Fit the two locking pins to the two right-hand corners of the trailer.
- Unlock the right-hand flap.
Wagenbouw HAPERT 27
Warning!
Before tipping, always check that:
- The load is no longer secured.
For type COBALT HM and COBALT+:
- The correct two locking pins are in place.
- The correct side flap or the rear flap is unlocked.
For types COBALT HB and INDIGO HT and INDIGO LT:
- The rear flap is unlocked.
5.0 Tipping using the hand pump:
To tip the cargo bed: place the hand pump’s valve in the “raise” position and use the
pump lever to pump until the desired height is reached.
To lower the cargo bed: place the hand pump’s valve in the “lower” position until the
cargo bed touches the chassis and then place the valve back in the “raise” position.
5.1 Electric tipping:
Use the key of the main power switch to turn on the system. (See figure 1) Turn the key
clockwise to activate the electrical system. The on/off button on the control panel needs
to be pressed 1 time to activate the control panel. To raise the cargo bed: keep the
relevant button on the control panel (see figure 2) pressed until the desired height is
reached.
To lower the cargo bed: keep the relevant button on the control panel pressed until the
cargo bed has returned to its rest position.
Turn the system off using the key in the main switch - turn the key to the left and
remove it!
See 3.1.1 and 3.1.2 for electric tipping using the remote control.
5.2 Electric tipping in combination with an emergency pump:
Electric operation: See “Electric tipping” for additional operating instructions.
Emergency pump operation: To tip the cargo bed: use the pump lever to pump until
the desired height is reached.

3.3 MAINTENANCE
Warning!
When working under the cargo bed:
Always support the cargo bed!
Maintenance by the user/service personnel
Wheel attachment:
After the first journey, check whether the wheel bolts are still sufficiently tightened. If
necessary, retighten them. Use the tightening torques table in the Specifications
chapter (5.1.1) to find the correct torque. Check the bolts every time a wheel has
been loosened, for example, to change a tyre (tighten the wheel bolts crossways).
Check the plug and the lights (dirt, corrosion and damage).
Check the tyres (tyre pressure, wear and damage).
Ball coupling:
Regularly clean and grease all sliding surfaces and bearing points.

Hydraulic pump oil level:
Check the hydraulic oil level and, if necessary, top it up.
For an electric pump: when the cylinders are in the highest position, the level must
be up to 10 cm below the edge of the cover.
For a hand pump: when the cargo bed is down, the level must be up to 1 cm below
the edge of the cover.
Battery, charge it if necessary:
A disconnected battery should be stored in a dry, frost-free location in your
warehouse (this is vital to reduce self-discharge to a minimum).
After a few months, the battery will have discharged itself and its condition should,
therefore, be checked. At 12.2 V (this is 80% of its capacity), the battery needs to be
recharged with a charger that has a capacity equal to at least 10% of the battery’s
capacity (e.g. a 90 Ah battery must be recharged with a charger of at least 8 A and
no more than10 A in order to obtain the best results).
This also applies to batteries that are installed in products in your showroom, so
please check their condition regularly and, if needed, recharge to 12.7 V (100%
battery charge).
If you neglect to do this, battery sulphation will irrevocably occur (lead sulphate that
attaches itself to the plates) and recharging will no longer be possible.
Sulphated batteries are not covered by warranty.
Attention!
You should never charge the battery with a quick charger.
Always use a trickle charger.
Depending on the type of trailer, it may have a plug socket for a battery charger.

Lubricating the overrun system:
Lubricate the grease nipples with grease (see figure 14) and the sliding parts with oil.

3.4 CLEANING
The trailer may be hosed down with water. We recommend that you do so if the trailer
has been in contact with salt (brine) or acids, as the zinc coating can be permanently
damaged by such substances. For new vehicles of which the zinc coating has not yet
fully hardened, white spots (white rust) or black spots may appear if the trailer is not
cleaned frequently enough. However, the protective effect of the zinc coating is not
reduced by the spots. To try to prevent these spots on hot-dip galvanised components,
you can take measures to ensure there is sufficient air circulation during storage, so no
water film develops between the metal surfaces.
Always make sure the electrical components do not come into contact with water or
other liquids!
