Warning
Safety

Krabat Sheriff is an active children’s
wheelchair for indoor and outdoor
use. The wheelchair accommodates
children in the age of approx 6 – 12
years. The wheelchair is lightweight
and the cambered wheels make it easy
to maneuver.
The sitting position is individually adjusted using height
and angle of seat, height of backrest, width of rear
wheels, position and different angles of the footrests.
The Krabat Sheriff has got a saddle seat, and the sitting
position is close to identical with the one of Krabat
Jockey. The use of this wheelchair should be determined
by your local physiotherapist or occupational therapist.
The Krabat Sheriff promotes a neutral position in the
hip and pelvic and abducts the hips. This together
with the wide support given by the footrests ensures
a wide base of support. The wheelchair 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. All together
it gives the child a close to ideal position for handling
the wheelchair.
The saddle seat enhances an active position rather than
a slumped and passive position. The upright and active
position also makes chest control and head control
easier, which again will benefit speech, swallowing
and respiration.
To ensure an optimal sitting position it is important to
try out and adjust the wheelchair before use. Do not
use the wheelchair unless an individual trial has been
carried out. Furthermore, do not let other children use
the wheelchair 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.
The wheelchair is developed and tested to accommodate
the maximum weight of 60 kg.

Main components
To obtain the optimal sitting position the height and angles of the seat, backrest
and footrests need to be adjusted. This should be done by a therapist who has
received training from Krabat AS, or a representative for Krabat AS
Most of the angles can be adjusted infinitely, or with the accompanying 4 mm Allen key situated under the seat.
Always tighten all screws after adjusting the wheelchair.
The wheelchair is for indoor and outdoor use on hard and flat surfaces.
If you do descend a hill lean towards the ground, avoid sharp curves and sudden stops. PS: The handbrake is a
parking brake. Do not under any circumstances use this brake when going downhill.
Always activate the brake when going in or out of the wheelchair.
The use of this wheelchair 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 wheelchair, 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 wheelchair.
It is important to get information about how to get in and out of the wheelchair. This should be done under the
individual trial or at delivery. Make sure the parking brake is activated before placing a child in the wheelchair.
Use
03.0
Place the feet on the footrest and tighten the belts. Children who use ankle-foot orthotics should wear these together
with their shoes, whilst sitting in the Krabat Sheriff S2.
The height of the footrests is done by adjusting the strap between the frame and the footrests. In order to do so
loosen the 4 screws which adjust the position forward or backward along the frame (fig. 02a). Each footrest is
mounted with 2 screws. We can adjust the width and angel of the footrest by loosening the front screw (fig. 02b).
By loosening both screws, we can adjust the rotation of the footrest (fig. 02b).
It is important to tighten the screws properly after adjustment.

Adjusting the angle of the seat
Place the child on the saddle seat and tighten the 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 both to maintain the position in the saddle seat
and to reduce the risk of falling out of the chair. It should be
used at all times. The angle of the seat can be adjusted by
loosen 4 screws under the seat, using the accompanying 4
mm Allen key (fig. 03) Adjust the angle to desired position
and tighten the screws.
It is important to tighten the screws properly after
adjustment.
The height of the seat can be adjusted by 2 screws under
the seat, where the rods are sticking up from the frame
(fig. 04). Simply loosen the screws and place the height
of the seat in desired position.
It is important to tighten the screws properly after
adjustment.
The height of the backrest can be adjusted and fixed
using the locking lever (fig 05). Open the locking lever
and fix it firmly at desired height. If the locking lever
does not fix the backrest properly, it can be tighten
using the plastic ring under the lever.

The tipping point can be adjusted by moving the seat
forward or backward along the frame. Simply loosen
two screws under the seat using the accompanying
4 mm Allen key (fig. 06). Slide the seat into desired
position and tighten the screws properly.
However, we recommend a representative from Krabat
AS together with the local therapist for this adjustment.
This is to ensure optimal point of tipping and safe use
of the wheelchair. When changing the point of tipping
we also alter the tipping angle.
It is important to tighten the screws properly after
adjustment.
The parking brake is activated by pressing the handle
in front of the seat downwards (fig. 07). The parking
brake locks both propelling wheels at the same time.
The parking brake is deactivated by pulling the handle
upwards (fig. 08).
Always activate the parking brake when taking a child
in or out of the wheelchair. The parking brake should
not be used whilst the wheelchair is moving. This could
cause dangerous situations.
The wires for the parking brake might need adjustment
when used for a period of time. If so contact Krabat AS
or a representative for Krabat AS.
It is important to tighten the screws properly after

The Krabat Sheriff S2 can be fitted with 2 anti tippers. The standard position with 24” propelling wheels gives us
a max tipping angle of 7 degrees. This can easily be altered to 14 degrees. Krabat recommend all users to have
anti tippers fitted.
The Krabat Sheriff S2 has Quick Release shafts. This ensures
a quick and easy dismantle of the propelling wheels, when
transporting the chair.
Press in the button in the centre of the shaft whilst pulling
out the whole wheel (fig. 11). Always make sure the button
pops out when mounting the wheel. This is an indication
of a fixed shaft and a wheel ready for use. Make sure the
propelling wheels are mounted as prescribed, to avoid
dangerous situations.
The backrest can be folded down towards the seat to make
the wheelchair more compact during transport (fig. 11).
Do not send the Krabat Sheriff S2 on a plane without suitable
packaging (crate, suitcase, etc.). Shipping of the Krabat Sheriff
without the suitable packaging can harm the product and
cause dangerous situations.
The Krabat Sheriff S2 is not approved for car transport. The
child must be seated in a car seat.
It is important to tighten the screws properly after
adjustment.
