1.4 Safety Information
Throughout this manual are many instructions to ensure your´s and other´s safety while you are using your
trailer. Be careful to read all safety information to prevent damage and dangers, when handling or using your
FoldTrailer FT752.
Towing a trailer gives the driver typical challenges like increased acceleration time, increased braking
distance, turning and reverse maneuvering, and certainly also safe loading responsibility. Loss of control of
the trailer or tow vehicle can result into damage or serious injury.
The most common causes for loss of control of the trailer are:
• Driving too fast for the conditions.
• Overloading the trailer.
• Loading the trailer unevenly.
• Trailer improperly coupled to the hitch.
• Inadequate towing vehicle.
• Inadequate towing hitch.
• Not maintaining proper tire pressure.
• Not keeping wheel nuts tight.
• Not properly maintaining the trailer structure and its running gears.
Since your FoldTrailer FT752 is a folding trailer developed for smart and space saving storage, there are
even more safety details which require your attention, for safe use of your trailer. These points are
mentioned specifically in the Folding chapter (3) and Maintenance chapter (4). Please read these instructions
carefully before starting handling the trailer.

1.5 Wiring Diagram
Your FoldTrailer FT 752 is equipped with DOT / SAE certified 12V electrical light system consisting of square tail
lights at the rear beam, and amber front side marker and red rear side marker along the sides of the trailer. All
lights are also in combination with reflex functions according to all requirements by the NHTSA. The drawbar is
equipped with a four pole standard electric coupler to attach the trailer lighting system to the towing vehicle´s
electric system. Before driving always check the function of the lights and that there are no damages to any of the
lights, reflexes or cables.

2 TOWING
As the towing vehicle may be used any car equipped with a certified towbar coupling. The total weight of the trailer and
cargo MUST NOT exceed the rate given by the vehicle manufacturer. All use of the trailer require attention to gross
weight, payload, coupling weights, load positioning and secure of cargo. In most countries and regions a trailer type
category O1 like FoldTrailer FT752 can be towed by any driver having a valid license for passenger cars (Drivings
license category B) as a minimum. Anyhow, be aware of possible variations in local legislation.
2.1 Pre-tow Check List
• Inspect the trailer for any structural failure; drawbar, frame, walls, suspension
• Inspect all bolts and fasteners that apply to your trailer
• Inspect the condition of the wheels; tire pressure (90 psi) and tighten the wheel nuts properly (90Nm)
• Coupler to be secured and locked
• Safety Breakage Chain properly rigged to tow vehicle, not to hitch ball only
• Make sure that the nose wheel is adjusted to its driving position
• Test of lights: Tail, Stop, Turn and Backup. Connect electric system to the car and provide testing
• Cargo properly loaded, balanced and tied down with a proper proportion of the weight on the tongue of the trailer
• Walls closed and latched. There is an option to secure the wall latches with a splinter pin
• Check that drawbar is latched to the trailer frame by both drawbar latches to be tightened properly with eye nuts
• Provide compactness check of the suspension by trying to move the trailer back and forth sideways by holding the
wheel. An appearance of major slack might have its origin in both wheel bearings and the pre-tension tightening of
the suspension system. If you suspect any such problem, contact your trailer dealer for advice or assistance
• Tighten the winch wire slightly before driving, the wire resting onto the bolt tube of the locking device front end

2.2 Tow Coupling
The ball coupler MUST be properly secured to the hitch ball of the towing vehicle. After assembly and attachment, pull
up and down on the ball coupler to make sure the hitch ball is fitting snugly on the hitch ball. No gap is allowed between
the coupler and the ball of the towbar. Arrange one safety chain around the car´s towbar hitch and another into a ring or
similar part of the towing vehicle, if the towbar is equipped with such for this specific purpose. Inspect your
coupler, safety breakage chain and nose wheel to make sure these are in proper working condition. The nose wheel
must point backwards when towing.

2.3 Loading
2.3.1 Coupling weight means the load on the car´s towbar ball when a loaded trailer is connected to the car. The
coupling weight must not exceed the allowed weight given on the manufacturers VIN number plate situated at the
front of the trailer chassis
2.3.2 Always check that cargo is properly positioned onto the trailer cargo platform. The coupling weight must not be
negative, means the trailer is elevating the car towbar, because of improperly positioned cargo. Too much coupling
weight or negative coupling weight can change the driving conditions of the tow vehicle and cause danger.
2.3.3 Never overload the trailer. Maximum allowed weight for the trailer is given on the manufacturers VIN number
plate situated at the front of the trailer chassis. Overloaded trailer may cause dangerous driving conditions and
damage to the trailer and its wheels. Overload driving is not covered by the warranty. Note also that smaller tow
vehicles may have lower allowed maximum weight for trailers than what is limited by the trailer itself. Check the
car´s towing registration before driving.
2.3.4 Secure the cargo properly to avoid cargo to fall off the trailer when towing, or cargo moving out of position
resulting into changed driving conditions and danger. Stop after a few miles and retighten straps and ropes if
necessary. For securing cargo both the platform internal tie-down rings and the external tie-down “hat taps” can be
utilized. Always use as many tie-down rings as possible. Make sure that ropes or straps or similar is not pressed
against sharp metal borders or the like. Always use straps and ropes etc. which satisfy the claims for cargo load.
2.3.5 The trailer may be loaded also with long cargo. Light weight long cargo can rest onto the box walls during
transport. In cases of heavy long cargo it is highly recommended to detach the front and rear walls, and fold down
the side walls, to position the cargo centred directly onto the cargo platform. Be careful to place the cargo in such
a way that the coupling don´t get negative weight. Long packages may also be placed and secured along the
trailer drawbar. Be careful not to provide any damage of the winch, the coupler or the nose wheel system. Towing
with long cargo requires special attention and rear end of long package must be marked properly. Note that you
have to check local legislation for towing long cargo and allowed length of such load.
2.3.6 At bulk freight, such as firewoods, stones, sand/gravel, soil or garbage etc. use of net or tarp is recommended.
Check your FoldTrailer dealer for additional equipment. Note that gravel, sand and soil has relative heavy weight
and there is a rather small volume limit to avoid that the trailer are being overloaded.

3 Folding
3.1 Security Instruction
Your FoldTrailer FT752 can be folded without load and on flat and solid floor only. The trailer must be disconnected
from the car when folding. Read this manual carefully before handling the trailer.
3.1.1 All folding handling of this FoldTrailer must always be accomplished by one adult person only. To prevent
damage, make sure no children or pets or expensive equipment or cars or the like are around while handling the
trailer.
3.1.2 Folding handling must be done without any load.
3.1.3 It is recommended to wear gloves during handling the trailer due to dirty parts and possible sharp steel profiles.
3.1.4 For security reasons it is highly recommended having one defined storage base for your FoldTrailer. Such storage
base must have a flat and solid floor without obstacles for the nose wheel, and a stiff and solid wall to lean the
trailer towards. It´s recommended having an in-house storage base, or as a minimum a storage base with a roof.
3.1.5 The storage base wall has to be equipped with a fastened bracket for the wall secure chain belonging to the
trailer. Extra bands or straps can be used additionally. Be aware that an unsecured folded trailer may fall off the
wall and cause damage and danger if someone climbs or pulls the trailer.
3.1.6 All folding operations are managed along the right side of the chassis (left side when folded), close to the winch.
3.1.7 Before any folding or unfolding procedure is started, always make sure that all included parts of the suspension
system, trailer chassis and the winching system, the wire condition included, is all right and fully functional. Any
damage or missing parts can result into damage and danger. If any doubt contact your trailer dealer.
3.1.8 At freezing temperatures, make sure that no flexible parts of the trailer are stuck by frost and ice. Check the
flexibility of any link or wheel or running gear before start folding or unfolding the trailer.
3.1.9 The trailer shall never be left unattended when it is only partly folded. If this still happens, always activate the nose
wheel brake.
3.1.10 When partly folded into an A-shape position, the FoldTrailer can be pushed sideways and also even turned by
lifting one rear corner by hand by holding the suspension rubber bumper bracket. Aware of sharp edges of the
trailer or its mudguards. In such cases always make sure that the distance between the drawbar nose wheel and
the trailer rear part at floor level is no shorter than 1 yard, and that the winch wire is kept continuously tensed. The
nose wheel must be un-braked and into a adequate direction when doing this.
3.1.11 When the trailer is fully folded at its storage base, the nose wheel brake must be activated, and the wall secure
chain must be hooked properly into the wall bracket ring.
3.1.12 Always read this Owner´s Manual if you are uncertain of any handling details. Ask your FoldTrailer supplier if you
are still having any handling requests.
