WT-Metall says thank you,
Thank you, for having chosen a Thermo dog trailer from WT-Metall. We would like to help you with
the following explanations and descriptions to get familiar with your trailer, so you can bring to
yourself the joy and happiness about having this trailer for a long time.
Obviously is the Thermo dog trailer the right mean to transport the dogs in the safest and most
confortable way. Whether you are on your way to training, or you travel to competitions and
exhibitions, your dogs will find the rest they need in the trailer, as well as the ideal temperature to be
in top shape!
However, you should always think of your dogs: taking them for a walk, spending time with them and
making sure that they have enough water at their disposal at any time.
We do strongly recommend that you check the welfare of the dogs every two hours while travelling.
According to the pets’ protection laws, it is not allowed for the dogs to spend a whole night
unwatched in a trailer all on their own. Therefore the dogs should also be checked at least every two
hours.
Good ventilation makes the maximum comfort much easier to reach.
Referring to dog trailers, the word THERMO
means, that the outside walls as well as the roof
and the floor of the trailer are thermally isolated,
so very little cold or heat can get inside from the
outside. Through the rosters on the doors and
the ventilation grills on the walls of the boxes can
enter fresh air. The air already used can go up
and leave the trailer through the extractor.
Through the extraction we create a circuit that renews the air inside the boxes. When the trailer is
being stopped and the dogs are inside, we do strongly recommend the further use of the ventilation
system.
In the models equipped with temperature regulator, the thermostat can control the extraction
function. Given optimal conditions we reach the outside shadow temperature (minimal temperature
in the environment). For the use of the thermostat, proceed as follows:
Turn the knob of the thermostat until it points a high temperature, e.g. 45°C, in this position the
ventilation system will not start automatically. Start turning it downwards until you hear a “click”.
That is the current inside temperature of the boxes. We leave the wheel at a position of e.g. 22°C and
the thermostat will run automatically when the actual temperature inside the boxes rises higher than
that. The best result to achieve will be the outside shadow temperature – if this temperature is e.g.
25°C, this will be the best result inside the trailer and the ventilation will not stop. If your trailer is not
equipped with a battery on board, you need the trailer to be connected to the car. Otherwise it
won’t be able to get power supply for the extractor and the light in the boxes.
In trailers with adjustable ventilation grills in the doors (Royal), these should always be open when
the dogs are inside.
While driving, and due to the speed, usually enough fresh air comes inside the boxes through the
ventilation grills. Therefore, the use of the ventilator/s is not always necessary under such conditions.
Exceptions: During traffic jams and by excessively slow driving.
Your number plate
Each different trailer model has two screws to hold the number plate when it is located on the back
left door. In case the number plate is located below the doors, between the reverse and the fog
light, the trailer has 3 screws to hold it.
Coupling
- Maneuver with the wheel of the trailer until it is straightened behind your vehicle.
- Pull the lever upwards with the index finger and the handle forward (open clasp).
- The open hook with the raised handle rest softly over the ball, at the same time that we
push down in order to fit the clasp with the ball.
- The coupling is ready with just a small pressure. The handle is moved downwards until it
is blocked. The coupling is perfectly accomplished when we hear a small “click”, when the
red part can be seen and the handle is once again in a 90° angle.
- The electrical circuit is being connected when we put the plug from the trailer into the
socket of the car.
- Before travelling, you must ensure that the lights and the ventilation system work
correctly.
- On trailers with brakes, the security chain of the clasp must always be mounted and be
used.
- On trailers with just one axle, the support bar located in the back of the trailer must be
put as high as possible and fastened with its holder.
- The jockey wheel must now be put back into its holder. Move it as high as possible and
secure it parallel to the tow bar.
- The wheel chocks are now to be removed from the wheels and brought back to their
holders.
Uncoupling
- Before uncoupling the trailer, we have to secure it with the wheel chocks so we can be
sure that it won´t start rolling on its own once free from clasp.
- We move the support wheel downwards until it touches the ground and the weight of
the trailer rests on it. We secure it.
- We unplug the trailers’ electric plug from the car and we put it in its guard, located on
the tow bar.
- Now we pull from the handle forward and the tow bar upwards, or we lift the tow bar by
turning the crack. One way or the other, the tow bar will raise and it will be set free from
the coupling.
- We lower the support bar in the back of the 1-axle-trailer to avoid that the trailer knocks
over itself when dogs jump in and out of the trailer.
The locking system in the trailer
Your trailer is usually equipped with lockable
key locks. You are able to lock/unlock all the key
locks with just the same key.
Please, write down the number of your trailers’
key on the first page of this manual. In case you
lose them you can order a new set by using this
number.
The key lock on the roof
This lock doesn´t only close the roof of your trailer, but also keeps the roof hermetically closed.
Closing the roof
- You have to check the state of the lock cylinders (if they are closed, you open them).
- Lower the roof slowly, holding the holder with both hands until it rests on the lower part
of the lock and it is ready to be closed.
- Push down with soft pressure over the lower part of the lock until you hear a click when
it gets completely closed.
- Check that it is well closed and turn the key cylinder to the horizontal position.
- The roof must be always closed and locked while driving.
- Never lock the key lock while the roof is in fully opened position.
Opening the roof
- Open the lock cylinder with the key.
- Once opened, open the key lock of the roof.
- Push the roof upwards by holding the roof holder with two hands.
- Do not leave the roof open without a reason for a long time, to avoid damages on the
roof hydraulic lifters.
Depending on the model you have, different electric options and configurations will
be found:
The functions « light in the roof » and « light in the boxes » are both controlled by a switch with the
positions on/off.
These switches, together with the one from the
extractor, will usually be found on the console
located in the roof.
If the extractor is connected to a thermostat, you
can control it by means of its wheel. In order to
reach the optimal ventilation when using the
thermostat, you have to meet the wheel with the
minimum outside temperature.
Height of the tow bar / hook device
In order to achieve perfect driving, we have to make sure that the tow bar and the hook device are
set to the optimal height to be hooked to the vehicle. This is particularly important for twin axle
trailers.
Unless otherwise advised, the tow bar of the trailer will be serially adjusted to 46cm.
The tow bar is hooked on to a device located under the main body of the trailer. This device allows
four different positions for the tow bar to be hooked, allowing us to obtain different heights for the
tow bar.
Tire pressure
For a four boxes trailer we recommend a maximum tire pressure of 1,8 bars.
For smaller trailers or roads in bad condition, we recommend a lower tire pressure to be used.
Please, contact us should further assistance be required.
The trailer should drive softly behind the car, without jumping, bumping or sliding to the sides.
Wheel covers
An overweight such as someone sitting down on them, to rest boxes with drinks or any other heavy
weights on them are to be avoided.
There is danger of the wheel covers to be stripped off, which would also cause severe damage to the
side walls.
First check-up after 300 to 500 km (186 to 310 miles).
- Check that the screws which keep the axle and the trailers’ profile together are tight, by
using a 19 mm wrench.
- Check that the screws which unite the tow bar with the axle are tight, by using a 19mm
wrench.
- Control that the two screws of the tow bar holder are tight, by using a 19mm wrench.
- Check the bolts of the tires with a 19mm wrench. (Maximum pressure allowed 110 Nm).
- Control that the screws of the support wheel holder are tight, by using a 17mm wrench.
- Check the inside doors with a 13mm wrench. The holding hinge with an 8mm wrench.
- Check the screws of the outside doors with an 8mm wrench.
Regular maintenance
- Keep the hydraulic roof lifters and the door holders free of dirt. Apply grease on the
joints and oil such as Balistol or WD 40 on the moving parts.
- All moving parts, the screws and the nuts must be kept free of dirt and greased regularly.
- The lock cylinder must be sprayed at least once in a month using oil such as Balistol or
WD 40.
- The rubber seals located in the inner side of the outside doors, must be treated with
talcum powder or silicone spray in order to prevent them from getting broken due to the
winter low temperatures.
- Check the air pressure of the tires and make sure that the minimum depth in their profile
is at least 1,6mm.
- After buying a new car, please check that the tow bar is still at the right height.
- Once a year, you should go over all the indications on the first check-up.
- Check that the bearings work properly. The maintenance-free bearings used on our
trailer have to be replaced completely if repair is required.
Cleaning and taking care of the trailer
Inside cleaning
- Take away the rubber mats or the wooden floor covering the floor in the boxes and clean
them individually.
- Sweep or vacuum all the dirt and hair from inside the boxes.
- Move the jockey wheel upwards as far as possible, until the trailer is in a slanting
position.
- Take away the screw which holds the middle wall between the rear boxes and take it out
of the trailer.
- Clean the inside of the front box/boxes (trailers with +2 boxes) or the front boxes (trailers
with 2 boxes) using water from a hose. By doing so, the hair, dust and any other filth will
move downwards until it leaves the trailer.
- Let the inside walls get absolutely dry before using them again.
- In the meantime until the inside of the trailer is dry, apply some multipurpose oil on the
roof hydraulic lifters and on the door holders.
- Clean and grease all of the movable parts, screws, bolts and nuts using grease.
Outside cleaning
The outside of the trailer can be washed by using none aggressive products.
Aggressive and corrosive products may cause the insulating effect of the walls from the trailer to get
lost. In case of using a hose with pressured water, make sure you always keep a roughly correct
distance from the trailer before using this pressured water. The water reaching the trailer with a too
high pressure will cause the insulating glue which keeps water away from seeping. As of that time,
the trailer will be permeable and will allow water to seep inside the trailer.
The trailer should undergo outside cleaning every three months.
Door adjustment
In order to guarantee that the water splashed by the tires doesn´t seep inside the trailer, it is
mandatory that the outside doors are tight and in the right position.
In case the outside doors are unevenly positioned or they have been moved or displaced, you can
bring them back into the right position by moving them a little bit in the desired direction. You need
a 8mm wrench in order to do that. With this wrench in hand, you shall untighten the outside screws
on the hinges slightly and bring the door back into place. Once the door is back into place, you
tighten the screws again. Very important: Don´t loosen the screws completely! They could fall back
inside the trailer’s framework.
If the inside doors are also displaced, you have to untighten the screws with a 13mm wrench and
bring them back into the right position.
Additional maintenance on trailers with brakes
If you have a trailer with brakes, there is no further maintenance to be carried out but to grease
those moving parts within the breaking system.
The greasing of such parts is required each 5000km (3100 miles) or once a year.
In addition to this greasing, you must oil the joints of the breaking cables (red cables), located under
the trailer. Such operation should be carried out once a year, ideally in spring.
The handling and specialized maintenance of the breaking system must be performed by authorized
and specialized personnel only.
