Introduction
The JETDEK skateboard is controlled by a wireless
handheld remote that allows instant throttle response
with smooth acceleration and deceleration. A number
of safety features are incorporated into the design
for ease of operation and reliability. The most important
is the integrated EABS electric-braking that actually
charges the battery when slowing down or stopping.
When the handheld remote
controller is switched on, a beep is heard to indicate
that all is well. If you hear this beep repeatedly
during operation, this indicates that th¬e 9V
battery inside the handheld remote is low on power
and has typically been used for more than one hundred
hours. This is an important safety feature, as in
a few minutes the hand held remote will no longer
be able to control the skateboard motor. This inability
includes the electric-braking function and the skateboard
will then only coast, like a regular one without power.
Therefore, using two rechargeable NiMH 9V batteries,
and swapping them to the charger routinely, is highly
recommended. And the more often you charge them, the
greater their overall longevity. This way you save
money and throw less away.
Another safety feature
prevents the skateboard from being used unless a person
is on the deck. A proximity sensor “feels”
your immediate proximity, allowing control, or removing
power should the rider step away from the deck. The
JETDEK is also designed to operate on a unique channel,
blocking any external radio interference and only
allowing the user to take control.
Last but not least, for sensible
progression, there’s a nifty operating-power
selector that lets you choose one of three skill levels.
This feature is accessed using one of three positions
of a switch inside the handheld remote. Using the
JETDEK beginner-setting for low speed learning, the
maximum travel range is also achievable. Go for the
intermediate-setting when you have more experience
with the JETDEK functions. And for maximum power and
speed, use the expert-setting.

Instructions
1. Charge the battery
before use. The charger plugs into an ordinary wall
outlet, and into the controller which is mounted under
the deck in a small aluminum box. The batteries are
fully charged when the light on the charger turns
from red to green.
2. Start by using the
beginner-mode even if you are an expert rider. Slide
the lid off the bottom of the pistol-style handheld
remote and carefully pull out the 9 volt battery.
Always shut the remote off, at the top of the pistol
to change modes. Then make sure the small sliding
switch inside is pushed right to the end, towards
the front of the pistol.
3. Do not forget your
padding and helmet.
4. Now turn-on the skateboard
power by pushing the red button on the controller,
opposite side to the charging port, until you see
a green light. And stand anywhere on the deck.
5. Flip the switch on
the top of the handheld remote and listen for a short
beep. The system is then ready to go! If you don’t
hear a beep, or you hear a repeated beep, replace
the 9V battery with a fully charged rechargeable NiMH
battery.
6. Lean forward before
using the remote throttle. Gently and gradually pull
the pistol trigger until the skateboard starts. You
will hear a slight buzzing, low frequency noise coming
from the skateboard. This is normal and can warn people
that a powered skateboard is in operation near them.
7. Make special note
that the electric brake is activated as you release
the spring-loaded trigger. So again, do this gently
for a gradual acceleration and deceleration. This
way you will maintain good control, as well as preserving
your electric-drive components like the belt, drive-wheel,
and batteries, reducing wear and the likelihood of
any premature failure.
8. Steer the JETDEK as you
would a regular skateboard.
9. For your safety, a JETDEK motor will stop and brake
automatically if you drop the handheld remote, or
step off the deck while riding.
10. To prevent battery discharge, both components
shut down automatically, after several minutes of
inactivity. After a few minutes of not being used,
a short beep is heard from the handheld remote as
it goes off. Then after a total of about ten minutes
a two-tone beep indicates that the skateboard has
shut off.

Maintenance
Electric skateboards
are extremely reliable, as there are very few moving
parts. So other than charging your battery at every
possible opportunity without delay to increase longevity,
the drive belt tension is of paramount importance.
Too tight is as bad as too loose. Belts, wheels, bearings,
and batteries are subject to wear and tear. Replace
them before they cannot be used normally.
Drive belt inspection:
A sawing noise on startup or stopping may be caused
by a slipping drive belt. If you suspect that the
drive belt is not properly adjusted, remove the lid
of the plastic belt-protection box by unscrewing the
two Phillips screws by the left back wheel. Inspect
the belt by rotating the wheel. A worn or stretched
belt should be replaced to preserve the drive wheel
sprocket. Now Press the belt with your thumb at mid-span
to assess the slack. Normally the belt should sink
about 5mm.
Drive belt adjustment:
If it feels loose or you have heard or felt any belt
slippage, tighten the belt by loosening the two Allan
bolts, washer-bolt nuts, and the kingpin nut. Push
the motor unit forward and retighten the nuts and
bolts. If the belt is too tight there will be unnecessary
stress not only on the belt, but also the bearings.
This will rapidly increase the likelihood of belt
breakage, and also reduce the life of the motor and
wheel bearings. Loosen a tight belt by moving the
motor unit back. To achieve proper tension you may
have to take out the belt, adjust, and put it back
in. See the belt replacement procedure.
Drive belt replacement:
Follow the inspection procedure. Then pull off the
wheel after carefully prying the chrome hubcap off
and undoing the axel nut. Place the new belt around
the motor sprocket and the axel. Slide the wheel back
on, rotating for the last bit to bring the edge of
the belt around the drive wheel sprocket and then
all the way on slipping laterally, bit by bit. Replace
the nut, and the hubcap. A little Tack-It on the hubcap
mounts will help keep them in place.
Bearing replacement: The
wheel bearings are press-fit and can be replaced using
hand tools after removing the wheels. Follow the drive-belt-replacement
procedure to remove the drive wheel.

tips:
1. Go for smooth operation.
Avoiding excessive acceleration will not only look
good and reduce the risk of personal injury, conservative
riding will also prolong battery life with a gradual
battery discharge, rather than a degrading rapid discharge.
2. Lean back before braking and maintain drive wheel
traction. Excessive unbalanced braking will allow
the wheel to skid and quickly wear out. The controller
has very efficient and powerful EABS electronic brake.
Braking smoothly will protect your driving wheel and
driving belt from extreme wearing.
3. Use a rechargeable 9 Volt battery for the handheld
remote, and recharge regularly. If during operation,
beeping is heard, your battery is in immediate need
of charging. This is a warning for your protection,
because neither the motor, nor the braking will be
functional in a few moments.
4. Set the handheld remote for beginners. The JETDEK
XT controller allows you to preset its maximum speed
in three ranges: 0-8 km/h, 0-15 km/h and 0-30 km/h.
To change the speed range shut off the controller
and open the lid on the battery box on the underside
of the controller. Slide out the battery and locate
the small three position switch as shown on the picture.
Slide the switch all the way upfront for the lowest
speed, slide it backwards one step for the medium
speed and one more time backwards for the fastest
speed range. Then turn on the remote controller again.
5. Use direct hand contact with the chrome ring on
the handheld remote. An unusual grasp or gloves can
interfere with your ability and the system may not
work properly.

General
Safety Tips
1. The JETDEK Skateboard is intended for use by persons
aged 10 or above.
2. Operators must comply with all local laws and regulations.
Check with your local police or transport department
to determine local requirements. Pay special attention
to local helmet and safety-gear laws.
3. Always wear your ANSI or Snell-approved helmet.
Elbow and kneepads are a good idea for protection
from injuries including laceration in the event of
a fall.
4. Do not operate the JETDEK Skateboard at night.
A JETDEK Skateboard is not equipped to be operated
in the dark or low light conditions. You will not
be easily visible to pedestrians or drivers without
sufficient daylight.
5. Ride only on smooth, hard surfaces. Most JETDEK
Skateboards are not designed to be used off-road.
The exception is the JETDEK AT800 which is excellent
on grass and gravel. In any case take caution when
rolling over any obstacles.
6. The electric motor, batteries, and controls can
be damaged if exposed to water. Do not allow the JETDEK
Skateboard to be used in the rain, nor to be driven
though puddles of water.
7. The product is designed to be used by one person
at a time. Product abuse will not be repaired without
charge, even during the warranty period. So do not
carry additional people or any cargo. And do not put
additional loads on the JETDEK Skateboard by pulling
or towing anything.
8. Your insurance policy may not provide coverage
for accidents involving this product. Contact your
insurance agent for more information.
9. Do not do stunts or jumps like you would do with
an ordinary skateboard. You might seriously damage
the JETDEK Skateboard and injure yourself or others
in the process. Be considerate, ride safely and with
style.

Mechanical
Safety Tips
1. Check all nuts, bolts
and mounted components to ensure the JETDEK Skateboard
is properly assembled.
2. Stop using the product
immediately if any part becomes loose. Correct the
looseness prior to resuming the ride.
3. Maintain proper tightness
on the wheel nuts. Too tight a pressure on the axle
increases friction, reduces speed and thus operation
time, as well as wearing the wheel material quicker.

1. Completely charge
the battery before riding the JETDEK Skateboard for
the first time.
2. Turn off the JETDEK
Skateboard and the remote controller when not in use.
3. Use caution when recharging
the batteries. Do not recharge in an area that will
allow the JETDEK Skateboard or the charging unit to
become wet. Recharge only in an area that is well
ventilated.
4. Keep children away
from the JETDEK Skateboard while it is being recharged.
5. Stop use of the product
or the charging unit if any wire becomes worn, broken,
or damaged in any way.
6. Do not modify the
electrical controls or wiring. Use only motors, batteries,
and charging units supplied or approved for the JETDEK
Skateboard.
7. Do not use the JETDEK
Skateboard battery to power or recharge any other
equipment.
8. Do not block the air vents
on the charging unit. If blocked, the charging unit
