immediately to a halt and turned off.
NOTE: The electrical systems of the scooter may disturb
the performance of alarm systems in retail shops.
DANGER!
4.10 SHARP TURNS:
Full speed turns should not be attempted. If you need to
turn sharply you must reduce your speed with the control
panel speed setting. This is particularly important when
travelling across or down a slope. Disregarding this
advice could lead to your scooter tipping over.
DANGER!
4.11 WEIGHT LIMIT:
• The user, plus options and accessories, plus items
carried should never exceed the total weight as listed

injury to you or others from scooter failure.
• Exceeding the weight limit will void the warranty.
• Do not hang shopping bags from the handlebars as
they could swing and cause loss of steering control.
4.12 HOT/COLD SURFACES:
WARNING!
After prolonged use, the drive unit motors will produce
heat, which is radiated through the motors’ outer casing.
• Do not remove the rear drive unit battery cover for at
least 30 minutes after using the scooter.
• Do not touch the motors’ outer casing for at least 30
minutes after using the scooter, to allow it to cool.
• Not only motors can become hot during the
operation of the scooter, but the seat upholstery
material and armrests may also heat up when
standing in the sun.
• Be aware that in extremely cold weather, exposed
metal parts can present a freeze burn hazard,
particularly if the hands are wet.
4.13 ROAD CAUTION:
Please show the utmost consideration for pedestrians
and other road users.
DANGER!
• Remember that the last thing a car or truck driver
expects to see is a scooter driving off the curb into
the road.
• If in any doubt, do not risk crossing the road until you
are certain that it is safe.
• When crossing roads, do so as quickly as possible;
there may be other traffic.
• Be seen! Always wear something bright such as light
coloured clothing, a reflective or day glow vest.
• To improve driver visibility, it is recommended to use
a safety flag.
• At night, in dull conditions or in poor visibility, always
use the lights, particularly when crossing the road.
• Obey all of the rules for pedestrians and traffic.
• Remember, when crossing the road you are a
pedestrian.

appropriate speed, (less than 4 mph/6 kph).

adjustment lever.
4.14 ADVERSE CONDITIONS:
DANGER!
• Be aware that when driving your scooter in adverse
conditions, e.g. on wet grass, mud, ice, snow or other
slippery surfaces, you may experience a reduction in
the grip and traction of your scooter. We recommend
you take extra precautions in these conditions,
particularly on hills and slopes. Your scooter could
become unstable or skid causing possible injury.
DANGER!
When you are using a powered scooter or wheelchair,
take extra care with loose or long items of clothing.
Moving parts, such as wheels, can be potentially
dangerous or even fatal if clothing becomes entangled.
NOTE: Extreme variances in temperature may trigger
the self protect mechanism in the control system. If this
occurs the control system will temporarily shut down to
prevent damage to the electronics or the scooter.

• Do not exceed the maximum slope of: S700 = 10° /
S425 = 8°.
• Stop and return the back rest to an upright position
before attempting to climb a slope. Failure to do this
may cause the scooter to become unstable.
• If you are in any doubt about the capabilities of your
scooter on a slope then do not attempt to drive up or
down the slope/curb; try to find an alternative route.
• Wherever possible always travel up or down the
slope directly facing the slope, (FIG.4.9).
• Never attempt a non-stop “U” turn when going up or
down steep slopes, (FIG.4.9).
• Be aware that accessories attached to the scooter,
may affect the overall stability.
FIG.4.9
4.19 GRADIENTS: ASCENTS:
When going uphill, keep the scooter moving if it is safe
and clear to do so.
Maneuver by using gentle tiller and throttle movements.
The seat should be set to its lowest height in its furthest
forward position and the back should be upright.
WARNING!
• If you have stopped on a hill, you should start off
again slowly.
• Avoid sudden acceleration or hard braking.
• Avoid hard turns.
• Be aware that stopping distances may increase when
traveling down hill.
4.20 GRADIENTS: DESCENTS:
WARNING!
• On descents, it is important not to let the scooter
accelerate beyond its normal level of ground speed.
• It is safer to proceed slowly down steep descents
(below the speed of 3 mph/5 kph) and stop, if any
anxiety arises regarding the descent.
• If the scooter picks up speed, release the control
lever to stop all forward movement, then restart
slowly and do not allow the speed to increase beyond
a comfortable level.
4.21 LAP BELT (IF INCLUDED):
Before using your scooter ensure the lap belt is worn and
correctly adjusted before use.
The lap belt is fitted to the scooter as shown in the fitting
photographs, (FIG.4.10 - 4.15). It is important that the belt
is fitted correctly and is not twisted.
To lock the belt:
Pull the buckle over your lap and push firmly into the slot
in the receiver, (1).
Ensure that there is no excess belt material, and the belt
is tensioned correctly. (FIG.4.10)
To release the belt:
Push the red button marked ‘PRESS’ to release the belt,
(2), (FIG.4.10).
DANGER!
• The lap belt is fixed so that the straps sit at an angle
of approximately 45°, and when correctly adjusted
should not allow the upper body to slip down in the
seat, (FIG.4.11)
• The lap belt is not suitable for use when the scooter
and occupant are transported in a vehicle.

• The lap belt must be checked on a daily basis to
ensure it is adjusted correctly and it is free from any
obstruction or adverse wear.
• Failure to make sure that the lap belt is secure and
adjusted prior to use could cause serious injury to
the user. e.g. too loose a strap may allow the user to
slip down in the seat and risk suffocation.
Maintenance:
• Check lap belt, and securing components, at regular
intervals for any sign of fraying or damage.
• Replace if necessary.
• Clean the lap belt with warm soapy water and allow
to dry.
• The lap belt should easily allow a hand width of
space between the body and the belt, (FIG.4.12).
• Sunrise Medical also recommend that the fit of the
belt is checked on a daily basis to reduce the risk of
the end user inadvertently re-adjusting the belt to an
excessive length.
• If in doubt about the use and operation of the seat
belt then ask your healthcare professional, dealer, or
carer for assistance.
For your comfort, the lap belt must be correctly fitted to
the scooter. If you are unsure about the fitting or opera-
tion of this option, please contact your approved Sunrise
Medical dealer.
