1.0 Introduction
Congratulations on choosing a BERG Toys go-kart! BERG Toys does everything to design and manufacture a
robust and safe product. You can now call yourself the proud owner of a product which you will be able to enjoy
for years to come.
The BERG go-kart is intended for long life, but it will need some maintenance work from time to time. Mainte-
nance will ensure a sturdy toy for many years. This user’s guide contains instructions for maintenance. Most of
the maintenance work on the go-kart can be carried out by the owner. For large repairs contact your BERG Toys
dealer, the place where the knowledge and the appropriate tools are available.

2.0 Guidelines for safe use
• Before using the go-kart, check if everything functions properly.
• Children may only drive the go-kart when supervised by an adult.
• A BERG go-kart is not allowed on public roads.
• Always drive at appropriate speed, depending on the situation.
• Driving down a slope slantwise, the go-kart may overturn.
• Downhill a considerable speed may be achieved, the braking distance will increase
• Sharp turns at high speed may cause the go-kart to tip over.
• Always pay attention to the environment.
• Riding backwards at high speed, there is a risk of losing control of the steering.
• The front wheels may become detached from the ground when braking while reversing at high
speed.
• Do not drive under the inuence of alcohol or drugs which have a negative eect on your perception
or reaction.
• Bumping and other stunts are damaging to the go-kart. BERG Toys can not be held liable for damage
thus inicted.
• Do not pedal backwards in an automatic freewheel (AF) when you are driving forward and vice
versa. Do not pedal forward in a brake freewheel (BF) or -3/-7 accelerator hub (BF -3/-7) when driving
backward. The gear may take over the pedals.
• Do not place unnecessary objects on or over the brake handle or the wheel.
• Make sure that brake and wheel can always function properly.
• Clothes and limbs may get stuck in revolving or hinged parts. Avoid loose attire such as scarves or
shoe laces. It can cause accidents.
• Avoid contact with the wheels when driving the go-kart.
• The rider or owner himself is responsible for assessing if the go-kart has the correct sizes (leg space,
seat height, distance to steering and brakes, etc.)
• Make sure that for every drive the driver’s seat is in the right position with regard to the pedals to
allow for safe driving.
• Do not get on or o while driving.
• Do not overload the vehicle.
• Do not drive in the dark without proper lights.
• Protective covers having been removed for maintenance purposes should always be put back in the
original state before use.
• When parking the vehicle, always put it in brake with the lock brake.
3.0 Maintenance
3.1 Frame
The frame is powder coated. This creates a hard coating. To prevent corrosion it is important to regularly clean
the frame. Should you want to grease the frame for the purpose of conservation, use only acid-free Vaseline.
Minor damage may be restored with some paint. The right varnish may be obtained from your dealer.
3.2 Wheels/Tyres
Regularly check the wheel rims and tyres for damage (cuts, tears, bumps). Warning: damage to rims and tyres
may cause accidents!
Tyre pressure should be between 1.0 and 1.5 bar. (Remember pressure increases at high temperatures). At he
right pressure, the go-kart drives smoothly and lightly. If there is not enough pressure the tyres tend to get punc-
tured more easily and excessive wear and tear occurs. If there is too much pressure the tyre can come o the rim.
This may lead to dangerous situations. (Be aware that pressure increases under high temperatures and in blazing
sun!) Avoid contact between the tire and oil, grease or fuel. Make sure the valve caps are always on.
3.3 Steering
The steering mechanism should regularly be greased for it to run smoothly. For the adjustable
wheel it is important that the identifying mark on the side of the inner control tube is not visible. See picture 1.
Picture 1
The steering mechanism of every BERG go-kart needs to be checked once a month for the following:
• breaking and/or damage of all parts of the steering mechanism
• controls (lubricate all rotation points)
• alignment front wheels (see pictures next page) for models with double ball steerage
• stuck bolts
3.3.1 Alignment front for models with double ball steerage
1) Check if bottom of strip is in upright position. 2) Then check the smallest deection of the left and
right wheel with the front bumper (As indicated in
the picture).
3) Loosen the steering swivel at the side of the
wheel with the smallest deection (see 2). Then
push against the wheel in the direction away from
the bumper (see indicator in the top left of the
picture). After that, tighten the steering swivel well.
4) Distance X = distance Y - 5 mm
3.4 Driving gear
3.4.1 Chain
The chain needs to be greased regularly in order to run smoothly. It should only be possible to push in the chain
2 to 3 cm in the middle. Make sure the rear axle does not move when the chain is pushed in the middle.
If the chain is pulled too tight, the go-kart will peddle heavily and the axle could break. If the chain is not tight
enough, the chain guard may be damaged. Tightening the chain for models with a square frame is carried out as
follows (see picture 2a):
Picture 2a Picture 2b
To tighten the front chain (see also picture 4b): loosen bolt C and bolt D a little and tighten the chain with bolt E.
Tighten C and D again. ATTENTION: the chain may NOT be TOO TIGHT. Remove the lower half of the chain guard
to check this. The chain should be easy to push in the middle for about 2 cm. The BF-3 and BF-7 models also have
a second chain. This back chain is tightened as follows: remove the protective plate from the back hood. Make
sure the hub remains exactly parallel to the rear axle (maximum 1 mm dierence in distance between rear axle
and the small axle of the brake hub left and right), as can be seen in the picture below (picture 2c). It should be
possible to push in the chain in the middle with the thumb for about 3-4 mm (picture 2d). After this, the front
chain is tightened.
