Roma Sport SK8R User manual

User Manual
WCMX Wheelchair

The Roma Sport SK8R chairs are hand-built as a bespoke sport product enabling the
user to participate in a sport in which conventional wheelchairs are not capable
of withstanding the dynamic / physical stresses the sport demands. As such, the
standard requirements of manual wheelchairs are not fully applied to these products.
The chairs are manufactured from carbon steel. The upholstery is heavy duty nylon.
Due to the nature of the sport, the chairs are classied as ‘Custom Made Devices’
under the MDD and as such are exempt from bearing the ‘CE’ mark normally
associated with Medical Devices. They do however have to comply with the Essential
Requirements of Annex I of the MDD.
Description
Each wheelchair has been to be used for the purpose of participating in wheelchair
use in a skatepark environment. It may also be used for everyday activities.
Intended Use
- Always check that there is no obvious damaged caused during the shipping
process.
- Fit the wheels to your chair.
- Adjust your seat to give for optimum seating position.
- Ensure that your backrest is correctly adjusted, giving you the maximum support
and comfort.
- If your chair is tted with an adjustable footrest, make any adjustments.
- Tighten any lap, chest or foot straps that are tted during use.
Upon receipt of your chair
Always ensure the frame is structurally sound and that there are no visible cracks
present. Make sure the main wheel axles are correctly adjusted with the wheels fully
secured to the chair. (Quick release button must be out)
Check there is no debris wrapped around castor axles or bearings and the castor
forks are secure – check for any excessive looseness in the castor forks and that they
rotate freely. The tyres should be checked for correct pressures before each use
(110 p s i ).
Regularly inspect your seat and back upholsteries for any tears, rips or degradation
of the foams as this could lead to injury. Also, check any straps tted.
Care and Maintenance

The frame has a 12-month return to base warranty in the unlikely event of any
material failure.
Due to the intended use, tyres, wheel bearings and upholsteries are not warranted
against normal wear and tear.
Should you require any further modications to your chair after use, please contact
Roma Sport to discuss your requirements.
Warranty
Footrest (Diagram 1)
The footrest can be adjusted for height. Please refer to the image below. The footrest
mounting clamps hold the footplate to each side of the main frame of the chair. Both
brackets must be adjusted equally. Depending on the adjustment required use an
allen key to slacken the bolt. Adjust the footrest to the required position and
re-tighten to x the footrest in place.
Adjustments
Axel Position (Diagram 2)
The rear axle can be adjusted forward or backwards to change the centre of gravity.
This is adjusted for personal preference as a more experienced user may prefer a
more ‘active’ axle position.
To adjust the position, loosen the four bolts on the underside of each axle mounting
clamp and adjust to the preferred position. Each side must be on the same position
indicator mark and then re-tighten the bolts on the clamps.

Upholsteries (Diagram 3 & 4)
The backrest and seat can be adjusted for tension so the user can determine the
amount of support they require. Shown below are the areas for adjustment. These
consist of hook and loop straps. These can be undone and re-xed to allow more
‘sag’ or tightened to provide more support.

Wheel Fitting / Removal (Diagram 5)
Your wheelchair comes as standard with quick release axles. To remove or re-t the
wheels depress the release button and remove / locate the wheel and axle into the
frame bush.
Before use, always ensure the wheels are secure and the release button is in the ‘out’
position.

Rear Shock Adjustment (Diagram 6 & 7)
Air pressure in the main chamber will allow you to change the hardness of the shock.
The rebound adjuster will control how fast the shock kicks back to ne tune the stroke.
You will nd that as these adjustments are variable just like where you use your chair
they will be something you change periodically.
Never modify your shock or chair frame. Any modication can lead to a broken
shock and serious injury.
NEVER attempt to disassemble or remove the shock if it is in a compressed state.
To maximum performance of the shock in any different situation, it is necessary to
adjust the SAG. The main reason of sag difference is all about the weight (chair or
own weight). When you set up the sag, please sit on the seat properly.
Make sure all your weight is on the seat and then observe the suspension travel ring
position which is on the shock travel body after getting out of the chair. We suggest
that the displacement percentage range is 15~25% of full travel.
The sag displacement will be decreased by adding air pressure or increased by
lowering air pressure. Adjust the air pressure to match your preference and
required travel.
Rear Shock (Diagram 6) Indicator Ring (Diagram 7)
Air pressure is lled to 150psi during production. Increasing the air pressure will make
the shock harder while decreasing the air pressure will make shock softer.
The rebound adjuster is the red circular knob next to the main air valve adjuster.
Turning the red circular rebound knob you can control the speed of your shock return
to be slower or faster.
It is necessary to adjust the SAG to get the best performance from your shock.
Please refer to Shock Specication Table. These gures are for reference only and
each individual may have a separate setting for different areas of use.

NEVER use a garage forecourt pump to increase air pressure in the shock. Use a
pump which is intended for high pressure cycle inner tubes or similar.
DO NOT disassemble the shock yourself, please contact your nearest Roma
authorised service centre if there appears to be a malfunction. Roma is not
responsible for any unauthorised modication to the shock.
Use only soap and water to clean the shock. Never use a high-pressure washer.
Maximum air pressure should be limited to 275psi. After approximately 100 hours
of use check the mounting bushes and xing bolts. Should any damage / excess
movement be visible replace before further use.
