General
Krabat Sheriff is an active children’s wheelchair for indoor and outdoor use.
Krabat S1 accommodates children in the age of approx 2 - 7 years, Krabat Sheriff S2 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 Sheriff. 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.
Attention: For the weak sighted we recommend to download the user manual for Sheriff S1/S2 at
www.krabat.no in PDF. Scale the document to desired size.

Use
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 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.
Avoid sharp curves and sudden stops when descending a hill. 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.
Footrests
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 S1/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 angle 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.

The width and angel is adjusted by loosening the

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.

Parking brake deactivated (upper position)
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 adjustment.
Use of the parking brake
The Krabat Sheriff S1/S2 can be fitted with 2 anti tippers. The standard position 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.
