Starting to use your wheelchair

2.2
Finding the centre of gravity - the point at which the
wheelchair will tip back
Your ability to control and safely tip the wheelchair depends
mainly on your seating position and the location of the centre of
gravity in respect to the rear wheels.
The JOKER ENERGY model does not allow any adjustment the
rear wheels due to its welded frame.
The correct position of the rear wheels depends on many
factors, among them: the occupant's weight, type of
disability and ability to manoeuvre the wheelchair.
The manufacturer will supply the wheelchair with the rear
wheels positioned according to instructions given on the
original order form. The wheelchair's setting can not
be modified after manufacturing.
Finding the point at which the chair will safely tip
back requires the presence of an attendant who must
be standing behind the wheelchair ready to prevent it
from overbalancing.
In order to find the point at which the chair will easily tip back
and, consequently, the range within which it is safe to
manoeuvre the chair, proceed in the follows (see fig. 3):
You are sitting on your chair. hold the hand rims on the rear
wheels firmly.
Then, move the hand rims slightly backwards and while
moving your weight backwards, push the hand rims forward
with a jerk and the front of the chair will rise.
At this point, by moving your body gently backwards and
forwards while moving the rear wheel backwards and forwards
using the hand rims, it will be possible to find the centre of
gravity and the point at which the chair will safely be
controlled.
IN ORDER TO PREVENT THE WHEELCHAIR FROM
OVERBALANCING
RECOMMEND MOUNTING ANTI TIPPER WHEELS
WHICH ARE SUPPLIED AS AN ACCESSORY TO
THIS MODEL.
