advisable to free-wheel it on a long or steep slope. If the attendant has any concern about

whether he or she can control the SnapDragon in free wheel mode, the user should not

remain in the SnapDragon while it is being pushed.

To reconnect the drive, twist the mushroom knobs to the "catch" position and allow the

SnapDragon to gently roll forward or backward a few inches. You will hear two clicks as the

drives reconnect, and the wheels will once again be controllable by the joystick or

attendant controls.

Wheels and Tyres

The tyres on a SnapDragon are 62-203 (12½" × 2¼") non marking pneumatic covers fitted

with an inner tube. As supplied they contain a puncture proofing compound which is very

reliable and will withstand damage from pins, nails and even small glass cuts.

The valve is a standard Schraeder (Car) type and the tyres should be maintained at a

pressure of 35 PSI (2·4 BAR) for best performance (this is written on the wall of the tyre).

If the tyre needs replacing it is best done with the wheel removed. This is easily done by

supporting the SnapDragon using the Jack-Leg located under the Gear-Box on the inside of

the wheel; flip it down from its spring catch and lift the SnapDragon on to it, rolling it

forward to lock it in place. Now undo the three nuts holding the wheel with a 17mm

spanner. Draw the wheel off taking care of the "mushroom knob" as you do so. The tyre

may now be replaced exactly as a bicycle tyre would be.

To refit the wheel place it over the three studs on the gearbox, fitting the "mushroom

knob" through its hole and replace the wheel-nuts. These should be done up firmly. Push

the SnapDragon forwards to release the Jack-Leg, and fold the leg back against the

undersideof the Gear-Box.

After extremely muddy walks it is even possible to remove the wheels and wash them

under a running tap or shower (since they are waterproof). This can be quicker than trying

to brush off dirt.

SnapDragon – Owner's Manua

To be able to push the SnapDragon, you can

disconnect the motor-gearbox drive to the

wheels. To do this, make sure that the

SnapDragon is on a flat surface for safety.

Then pull each of the black "mushroom"

knobs (one on each wheel) and twist them

a quarter turn to catch in the "out" position

(see Fig:9). This allows the SnapDragon to

be pushed. The top of the elevator frame

acts as a convenient push handle.

Remember that the SnapDragon has no

electronic brakes in this condition and is a

heavy piece of equipment. It is is not
