10. Cleaning & Maintenance
10.1 MAINTENANCE (Logging of and frequency)
A record of product servicing and maintenance should be kept for each Trekker or Tiny
Trekker.
Frequency of servicing and maintenance is dependent on the behaviour of the user. A Trekker or
Tiny Trekker used by a heavy duty user should be serviced and maintained more frequently.
A minimum monthly service check should be carried out and recorded. If a Trekker and Tiny
Trekker is being re-issued, the new user must be issued with an up-to-date set of user instructions.
Refer to the Medical Devices Agency Bulletin DB9801, supplement 2, for guidance on the safe
re-issuing and disposal of Medical Devices.
All Trekkers and Tiny Trekkers returned to your equipment provider for servicing or otherwise,
must be cleaned and de-contaminated before being returned.
10.2 MAINTENANCE SCHEDULE
If there is any doubt as to the condition or functionality of your equipment take it out of use
immediately, label it, and inform your colleagues and your equipment provider of your findings.
Similarly, if you suspect that the equipment is not suitable for the user, do not proceed to use
it and contact your equipment provider for advice. As well as following the schedules, always
be vigilant concerning this equipment.
Weekly
1. Check that the spring poppers always fully engage when unfolding the walking frame.
2. Check the front and rear wheels for ingress of dirt or anything that would prevent the wheels
from rotating freely.
Monthly
1. Check wheels for signs of wear or damage. Contact your supplier for replacements if necessary
to avoid equipment instability. Should uneven wear be evident please contact Quest 88.
2. Check all hand-wheels to ensure that they lock all moving parts securely and easily.
3. Check all nuts and bolts are firmly secured.
4. Check that the equipment folds freely and is not impeded.
5. Where directional locking devices are fitted to equipment, check that the walking frame runs
in a straight line by rolling it on a flat surface.
6. Check that braked front wheels do not rotate whilst the brake is engaged.
7. Check that pelvic/chest ‘width adjustment’ screws and chest ‘pivot cleats’ firmly hold their
position.

Trekker from the frame’s upright tubes.
Slide one support harness bracket on
each side of the chest rail towards the
closed end of the rail.
Re-insert the chest rail into the frame.
Repeat the procedure with the two
remaining harness brackets. Align the
brackets and tighten the white hand-
wheels. You can now clip on the support
harness.
The harness must be used in-
conjunction with the chest and hip
supports.
This accessory is to be used as a
support only. It is not intended as a seat.

7. Adjustments continued
7.6 Hand rail adjustment
The height and the extension of the hand rail are in part, dependent on one another due
to the angles of inclination of the tubing involved. It is therefore, it is advisable to adjust
both height and extension simultaneously.
To do this release the hand-wheels “B” and “C” and position the hand rail such that the
patient can grip it comfortably. Elbows should normally be straight and the bar approximately
level with the top of the chest support. Re-tighten the hand-wheels.
8. User Transfer & Stability
Once fully adjusted,before transferring the user, ensure that all supportive components
are fully secure and that the front wheels are locked. Fine-tuning of hand rail length and
height, as well as chest support height, may be adjusted after transfer with some practise
as long as the user is fully supported during this process. This equipment must be used
under supervision at all times!
In a few cases, it may be found that these adjustments allow the patient to be positioned
only a short distance ahead of the rear wheels. Additionally, some patients will present with
uncontrolled jerking movements which can threaten to tilt the frame backwards. In such
cases the Trekker and Tiny Trekker should not be used.
Similarly, carers should be aware that in exceptional cases the transverse stability of the
frame can also be threatened by vigorous uncontrolled movements, particularly where the
patient’s height is at or near the maximum recommended. In such cases the Trekker and
Tiny Trekker should not be used.
9. Folding & Storage
The Trekker and Tiny Trekker can be folded by reversing the un-folding procedure. Note
that poppers can be released by pinching them into the tube. When folded the Trekker
and Tiny Trekker can be locked in place by tightening the hand-wheel with the yellow
dot.
Please adhere to best manual handling practice whilst transferring, folding, un-folding and
lifting the Trekker and Tiny Trekker.

7. Adjustments
7.1 Centralising the user
In order to ensure the stability of the frame when in use, it is necessary for the user to be
positioned centrally in the frame.
7.2 Setting the overall height
N.B. Refer to the table on the rear page for the maximum height settings for each size of
frame. It is crucial that these values are not exceeded.
Height adjustment is achieved by releasing the hand-wheel “A” and extending the top
sections of tubing (see step 1). Note that maximum height marks are to be found on
these tubes which indicate the limit of adjustment. Re-tighten hand-wheel “A” after
positioning.
a) Measure the height of the patient from heel of shoe or orthosis (if worn) to 50mm below
the axilla.
b) Set the overall height of the Trekker and Tiny Trekker (measured to the top edge of the
chest support) to this dimension. Ensure that both hand-wheels are fully tightened after
positioning.
7.3 Hip rail adjustment
The anterior hip rail is positioned by first releasing the M5 hexagon head socket screws
which allow both height, forward, and backward adjustment. The height to the bottom
edge of the hip rail should be approximately 25mm above the Greater Trochanter (hip
flexion crease). The position forward and backward should allow approximately 5° hip
flexion in the standing position. The posterior pelvic strap should hold the patient firmly
against the hip rail. Re-tighten the M5 hexagon head socket screws.

7. Adjustments
7.4 Setting the angle and width of the Chest and Hip supports
The chest support will normally be fitted in a horizontal position during manufacture but it
may be tilted to improve comfort for the user by releasing M6 hexagon head socket screws
as shown below. After re-positioning, re-tighten the M6 hexagon head socket screws.
Note: If it is found necessary to alter the position of the chest support then the previous
adjustments to chest support height and hip rail height may need to be changed.
The chest support can be adjusted by releasing the clamping blocks as shown. It should
be wide enough to allow small medio-lateral movements to aid weight transference when
walking, but not too wide to allow excessive and unwanted trunk movements. Thus,
depending on the size of the patient, a chest pad may also need to be the fitted for
additional cushioning when supplied to the patient.
The hip support can be adjusted by releasing the screws on the clamping blocks. The hip
support should be wide enough to allow small medio-lateral movements to aid weight
transference, but not too wide to allow excessive and unwanted trunk movements.
The fabric coverings for the chest and hip support can now be replaced.
7.5 Abduction pommel support
The height, forward, and backward position of abduction pommel can be adjusted by
releasing the indexing lever and plunger hand-wheel. Re-tighten the plunger hand-wheel
and indexing lever after positioning.
