01 - General
This user manual gives an overview of the
Krabat Jockey with both electric and
manual elevation of the sitting unit.
Krabat jockey comes in two different
sizes. Many configurations are possible
with different accessories.
Krabat Jockey is an active chair for children
between the age 2 –14 years (2 sizes). The
chair is height adjustable and can be adjusted
from floor level to the height of a kitchen
worktop. The sitting position can be adapted to
the individual child. All angles and positions can
be set infinitely. An occupational therapist or a
physiotherapist should determine the use of
this chair.
The excellent sitting position provided by the
Krabat jockey is due to both the saddle seat,
which promotes a neutral position in the pelvis
and abduction in the hips, and the footrests
that support the feet in an optimal position.
The chair promotes good stability in the lower
body and gives the spinal column natural
curves. This provides a good base for balance
and activity in the trunk and upper body. The
saddle seat enhances an active sitting position
rather than a slumped and passive position.
The upright and active position will also benefit
speech, swallowing and respiration.
To ensure an optimal sitting position it is
important to try out and adjust the chair before
use. Do not use the chair unless an individual
trial has been carried out. Furthermore, do not
let other children use the chair without an
individual trial.
As children grow they change their movement
and sitting pattern on a regular basis. It is likely
that the child will need another size of the
sitting unit or other adjustments. Contact your
local physiotherapist or occupational therapist
if the product is not optimal or if adjustments
are needed.

03.0 - Use
To obtain the optimal sitting position the angles of the seat, backrest and
footrest need to be adjusted. This should be done by a therapist who has
received training from Krabat AS, or a representative for Krabat AS.
All angles can be adjusted infinitely. The individual footrests can be adjusted by loosening the 4 screws
shown in fig. 05. The footrest-in-one can be adjusted using two screws shown in fig. 06. The sitting unit
can be adjusted using the turnbuckle shown in fig. 07. The angleof the backrest can be fixed in different
positions using the locking lever shown in fig. 08.
The use of the chair should be discussed with your therapist or someone who knows the child well. It
is important to establish in which situations the child should use the chair, how long they should use
it and when to progress the time spell. This needs to be evaluated continuously as the child gets
familiar with the chair.

03.1 - Individual footrests
03.2 - Footrest-in-one
Place the feet on the footrests and tighten the belts.
Children who use ankle-foot orthotics should wear
these, together with their shoes, whilst sitting in the
Krabat Jockey. The height of the footrests is
adjusted by sliding them up or down the tracks, or
simply by adjusting the length of the strap which is
attached underneath the seat. It is also possible to
attach ankle straps on the footrests. These will need
adjustment to ensure the child’s foot is in the
correct position.
Fig. 05
Adjustment of individual footrests
The height of the footrests is adjusted by sliding
them up or down the tracks, or simply by
adjusting the length of the strap which is attached
underneath the seat. It is also possible to attach
ankle straps on the footrest. These will need
adjustment to ensure the child’s foot is in the
correct position.

03.3 - Angle of the sitting unit
03.4 - Angle and height of backrest
Note: The turnbuckle has a spring loaded plunger
functioning as a mechanical end stop.
If the end stop is engaged when increasing the
seat angle, it has to be released if seat angle is to
be decreased. Release the end stop by pulling the
plunger and turn the adjusting tube on the
turnbuckle to adjust the seat angle.

Place the child on the saddle seat and tighten the
hip belt. Make sure the child is placed well into the
seat in the midline position with symmetry in the
legs / lower body. Use the hip belt to both maintain
the position in the saddle seat and to reduce the
risk of falling out of the chair. The hip belt should
be used at all times when Krabat jockey is in use.
The angle of the sitting unit can be adjusted using
the turnbuckle underneath the seat. The angle is
self locking and does not need to be fixed.
Fig. 07
Adjustment of the seat angle using the turnbuckle
The angle of the backrest can be adjusted and fixed
using the locking lever. If the locking lever does not fix
the backrest properly, it can be tighten adjusting the
plastic ring under the lever. The height of the backrest
can be adjusted by loosening the locking lever before
sliding the backrest up or down in 5 different position,
each with 1 cm interval. Remember to fix or tighten the
locking lever when you have achieved the correct
height.

03.5 - Adjustment of the side supports - Jockey Plus
03.6 - Adjustment of the height - Electric elevation
Note: When a user is seated in the chair and the chair must be moved, e.g. from room to room, it is
recommended NOT to do this with the seat in the highest position (!)
To prevent the chair from accidentally tipping, never move the chair with the seat in the uppermost
position.
The side supports can be adjusted up or down
by loosening the screws shown in figure 09. It is
enough to loosen the screws, dismantling is not
required. Tighten the screws after adjustment.
The side supports can be adjusted in or out in
the same way.
Fig. 10
Adjustment of the side supports
The adjustment of the height is controlled by the
remote control. The remote control, shown in
figure 10, has one button for elevation and one for
lowering. As soon as you let go of the button, the
movement will stop. A beeping sound will be heard
when the sitting unit is in the highest or lowest
position, to let us know the sitting unit has reached
the end position.
If a beeping sound is heard whilst the sitting unit is
moving up or down, the battery needs charging.

03.7 - Battery and charging unit
Fig. 12
Charging of the battery
The Control box is located under the under-
carriage as described in figure 2. When a battery is
inserted into the Control box, an audible beep
indicates good connection and the chair is ready
for use. When a fully charged battery is inserted
there are magnets in the battery to ensure the
correct position in both holder and charger.
If a beeping sound is heard whilst the chair is not
in use, the battery needs charging. The same
applies if a beeping sound is heard whilst the
sitting unit is moving up or down.
To charge the battery, remove it from the Control
box and insert it into the supplied charger cradle,
connect the cradle to the charger and connect the
charger to supply mains using the power cord.
When connecting the charger to a socket using the
power cord, a yellow light will indicate power.
Refer to fig. 12: A flashing green light will indicate
the battery being charged. When the battery is
fully charged the green light will glow
continuously.
Charging an empty battery will take approximately
5-8 hours. This type of battery (NiMH) tolerates
charging even if it is not totally discharged.
If the battery runs empty during operation, remove
battery for recharging. The chair’s elevation will not
work with an empty battery (or without a battery
at all), but the chair is still safe to use.

08.0 –Troubleshooting.
If you experience any electrical problems with the Krabat Jockey, e.g. no elevation of the seat unit, or
any unexpected stops when in use, please do the following:
If elevation doesn’t work:
-Check that a battery is inserted into the Control box
-Check that the battery Is correctly inserted
-Check battery charging status
-Check that both cables are inserted into Control box
-Check that the Hand control is properly connected to the Control box
-Check cables for cuts or kinks
If battery is low on voltage or discharged, please charge battery (see 03.7, page 14).
If elevation stops working when in use:
-Check for audible alarm (beep) that indicates low battery voltage
-Check that the battery Is correctly inserted
-Check battery charging status
-Check that all cables are in good condition and properly connected
Make sure the battery is fully charged and inserted correctly into the Control box before use. If you
experience a shutdown and have gone through all necessary steps above, and the elevation on the
Krabat Jockey still doesn’t work, please contact Krabat or a Krabat representative to get the problem
fixed.
Note: If you experience a shutdown and the Krabat Jockey’s elevation doesn’t work, It is still safe
to use the Krabat Jockey if the battery is removed.
