7. Intended use / intended user
The Blazer powered wheelchair is meant to provide mobility to persons who
are not able to walk, stand or use a manual wheelchair, but who are very well
able to control and use the interface of a powered wheelchair. The wheelchair
is designed for a maximum user weight of 136 kg.
It is strongly suggested to have the use of the wheelchair evaluated by a
trained doctor, therapist or other qualified and trained staff.
This wheelchair is not suitable for persons who do not have the cognitive skills
to drive a powered wheelchair by themselves. Also it is not suitable for visually
impaired persons.
8. Intended environment
The product is not restricted to only indoor or only outdoor use. Because of the
large wheels placed in the rear, the wheelchair is able to cope with many
terrain differences. This, combined with the compact size of the product and
the excellent speed range and battery capacity, making the wheelchair
suitable for both indoor and outdoor use. It is allowed to use the wheelchair in
different weather conditions. It can be used at temperatures of -25 degrees up
to maximum 55 degrees Celsius and the charger operate temperatures is 0 up
to 40 degrees Celsius. It however must be noticed, that metal or plastic
surfaces of the wheelchair can become very hot when exposed to direct sun
for longer time. Because of the harmful combination of salt water and sand it is
advised not to use the wheelchair on beaches. We advise to clean the
wheelchair after having been in contact with sand and/or salt water as
described in the paragraph “cleaning”.
9. Tyre pressure
The product uses air-filled tyres in the front and solid or air-filled tyres in the
rear. The choice of having solid or air-filled rear tyres is made by the user
during the ordering of the wheelchair. In order to prevent tyre damage and to
preserve the performance of the wheelchair, the tyre pressure must be
checked at least on a monthly basis. The tyre pressure should be:
Front air-filled tyres (small): max. 350 Kpa / 50.7 PSI / 3.5 bar
Rear air-filled tyres (large): max. 350 Kpa / 50.7 PSI / 3.5 bar
The tire pressure is also shown on the stickers in the rims of the chassis

should pay great attention to make sure the cables are not jammed between
the battery and the battery box.

10.1.6 Main fuse
The chassis contains a circuit breaker which is located at the rear of the
chassis. The circuit breaker protects the whole electrical system of the
wheelchair.
Circuit breaker location
This circuit breaker will pop-up when the electrical system is over-load. Once
the breaker pops, you will not be able to control the wheelchair by joystick.
This situation happens typically when the wheelchair is climbing up a hill that
is steeper than what is restricted. Should the circuit breaker pop-up, you need
to eliminate the cause first. And then, push down the circuit breaker. You will
be able to drive again.

Captain Seat. The choice is made by the user during the ordering of the
wheelchair. Please identify firstly which one is mounted on your Blazer.

seat-to-back angle. It can be up-graded into manual recline or power tilt. The

provide optimal seating comfort and support to the user. The cloth is air mesh.
The seat cushion is well fixed with Velcro on to the seat pan to prevent it from
sliding. The Captain Seat surface is made with PU material.
10.2.2 Seat tilt (Sling Seat only)
The seat tilt in Blazer model can be used to release pressure. The tilting angle
is from 8 to 28°. The tilt can also be used when driving down a slope for
compensating the negative seat angle. This provides a more stable seat
position and safe driving.
If the tilt is activated over a certain angle, the driving speed will be reduced.
This is to reduce the risk of danger whilst driving at high speed.
Always drive carefully on slopes. The angle of the slope has great
influence on the total stability of the wheelchair.
When tilting, always check if there are no obstructions close to the
wheelchair. Especially in the front or rear of the wheelchair.
When tilting, the wheelchair will get longer. This has influence on the
driving characteristics of the wheelchair. Make sure there is enough
space to drive.
