Everest Lite Owner's Manual
Check controller & park brakes
Perform the following at least once a week. It should be carried out on a level floor in a
quiet area with at least one meter (40 inches) of clear space around the wheelchair.
Turn wheelchair power on. Check that after one second the power indicator lights re-
main on. Push the joystick slowly forward until you hear the brakes release. The wheel-
chair may start to move. Immediately release the joystick—you must be able to hear
the park brakes operate within a few seconds. Repeat the test three times, pushing the
joystick in reverse, left and right, respectively. If there is a problem, do not operate the
wheelchair. Contact your dealer. There are no serviceable parts in the controller. If you
have problems with this component, see Section IX, TROUBLESHOOTING; if you are un-
able to resolve them, contact your Graham-Field Health Products dealer.
Repairs of the electromechanical park brakes, which keep your Everest Lite from rolling
when stopped, should only be performed by an Graham-Field Health Products dealer.
Clean frame
Needed: soft cloth, mild soap and water solution
Wipe off base and seat frame frequently, at least once a week, using a soft cloth. Dry the
wheelchair immediately if exposed to moisture. Clean frame every three months with
a mild soap and water solution. The frame does not need to be waxed. Do not use sol-
vents, abrasive waxes, caustic chemicals or spray silicone. Never use abrasive cleansers;
they could scratch the finish. Never use steam or high pressure cleaners.
Check & clean upholstery
Needed: soft cloth, mild soap and water solution
Check back and seat upholstery material at least once a month. Inspect for rips, tears,
sagging, and worn spots.
Clean back and seat upholstery material at least once a month with a soft cloth and a
mild soap and water solution.
Check arms
Check arms at least once a month. Inspect for sharp edges or cracks which could weak-
en the armrest. Ensure that all attaching hardware is present and tight.
Check footboard
Check footboard at least once a month. Inspect the mounting hardware to confirm that
all fasteners are secure so that footboard will not accidentally slip. Check for cracks,
burrs or sharp edges.
Check caster forks
Check the caster stems/forks for proper rotation at least every three months. The caster
forks must swivel freely to facilitate steering and handling. Adjusting the stem nut varies
the amount of force required to turn the caster. If the nut is too loose, the caster will flut-
ter or shimmy; if the nut is too tight, the wheelchair will be difficult to steer. If the caster
requires adjustment, or the caster stem bearing requires replacement, visit a qualified
Graham-Field Health Products dealer. Ensure that stems are firmly attached to forks, and
that forks and stems are not bent. Evaluate all threads, locking nuts and bearings.
