Invacare Variance Plus - Manual (Page 23)

Remember that in order to preserve the interchangeability of wheels on
wheelchairs fitted with quick release wheels, both tyres must be inflated to the
same pressure.
Whenever a tyre is flat, it may be necessary to remove the tyre from its rim.
(photo 10)
Force the air out the the inner tube by pressing valve A.
Stretch the outer case on the rim. Repair or replace the inner tube. Put the
inner tube back in place. Reposition the outer case on the rim. Re-inflate the
tyre to specified pressure.
Note : It may be necessary to use one or two tyre-levers (Not supplied).
8.3.2 Handrims
- The handrims are used for propelling the
wheelchairs. The handrims are anodised
aluminium, chrome-plated or coated with anti-slip
plastic.
Note : As the handrims are in contact with your
hands, make sure that they are not damaged.
There is a handrim capstan set for persons
who have difficulty gripping. Its fastening and
positioning must be carried out by your distributor
in accordance with the qualified health advisor.
8.3.3 Axles
- The axles link the rear wheels to the frames.
They are either fixed or the quick release type.
- Use : (Photo 11). Push in pin A of the quick
release axle and insert the axle in the centre of
the rear wheel hub. Take the wheel fitted with
its axle and insert it in the hole B of side-frame
until the unit is blocked. Ball-checks must extend
beyond the bearing. There must be no substantial
play.
- Adjustment : Take the quick release axle off and adjust the nut-screw in order
to reduce play to a minimum.
IMPORTANT NOTE : Check that the pin of axle
and ball-checks are completely disengaged before
using the wheelchair.
It is ABSOLUTELY ESSENTIAL that the ball-
checks protrude at the end of the rear wheel axle
bearing, in order for them to be properly blocked.
Check the cleanliness of the ball-checks.
Warning : Never remove any wheel while the
user is in the wheelchair.
