Reconditioning - Invacare XLT Power U-front Service Manual

Reconditioning

Lubricate all movable parts if they are sticking or squeaking with a dry teflon based
spray, e.g. Viso 900-B5.
Screws and nuts: Check that all screws and nuts are tight.
Chassis: All parts must be checked for cracks or other damages. Pay special
attention to areas close to welds. If damages are discovered the chassis must be
discarded.
Back rest: Check that the angle is easy to adjust, that it is esasy fold down and
that it locks as it should.
Push handles: Check that the external push handles are firm and that the screws
are tight.
Back and seat covers: Check that the velcro strips are intact and stick and that
the covers are intact, if not we recommend that torn parts are exchanged.
Sideguards/armrests: Check that they are intact and easy to remove and put
back.
Anti-tip device: Check that the anti-tip device is easy to raise and lower, and
that the screws holding the anti-tip device in place and in the correct position,
are tight.
Rear wheel attachment: Check that the screws on the rear wheel attach-
ment are tight. That the axle housing is correctly placed and tightened with a
manual and dynamometric wrench calibrated to 45 Nm. The axle housing must be
assembled with a sideguard of at least 3 mm and armrests at least 12 mm outside
of the axle housing.
Rear wheels: We recommend that the tyres are changed if the pattern is worn.
Missing spokes are replaced, loose ones are tightened. Especially on solid wheels
there is a risk of spokes becoming loose. Fasten the hand rim if it is loose. Feel the
hand rim to check if it is smooth and that no sharp bits are sticking out. In that
case exchange it. Check that the rear wheel axle is completely inserted into the
axle housing, and that the two locking balls stick out behind the axle housing and
locks the axle. Check the air pressure in the tyre. Correct air pressure is stated
on the tyre.
Castors: Remove the castors and clean the castor forks from dust and dirt.
Reassemble and check that the castors turn and rotate smoothly. If the castors
are air filled, check the pressure and pump them. Correct air pressure is stated
on the tyre. If the castors are solid check for cracks and decide if they need to
be changed.
Angle adjustable castor housing: Check that the castor housing is at a straight
angle (90 degrees) towards the floor. Tighten the screws.
Brakes: Check that the brake pin is not worn down. If the pin is worn it should
be changed for safety reasons. Check that all screws are tight. Test the brakes
with the correct air pressure in the tyres. In a braked position the pin should
press down the tyre 5 mm. If the brake pin is moved to another position, it is
important that thread locking, Loctite, is used in order to prevent the brake pin
from coming loose. When moving the brake pin it may be necessary to warm the
brake pin/screw with a heat gun. At the factory the brake pin is tightened with
thread soldering to prevent it from unthreading.
