USE AND SAFETY

WHEEL LOCKS

Engage both wheel locks before getting in or out of chair,
leaning forward in chair, or while in an elevator or wheelchair
lift. Proper adjustment of wheel lock is at least 1/8" when
locked. Locks are engaged by pushing handle completely
forward. Adjustments to locks are made by loosening or
tightening nut on the carriage bolt. Embed lock shoe at least
1/8" by sliding clamp toward rear wheel while handle is
engaged in locked position. Tighten nut and bolt to secure in
position. Test for correct locking action before actual use.

TIRES

Solid rubber tires need minimal maintenance, but should
be cleaned occasionally with a damp cloth. Replace if tires
become severely worn or cracking appears.

FRONT CASTERS

Casters should be checked periodically and lubricated
occasionally. Lubricate by removing fork and greasing caster
stem bearings. Lubricate wheel bearings by removing wheel
from fork. Reassemble fork and wheel by tightening nuts until
no play remains, but wheels roll freely. If nut is too loose,
caster will shimmy, if too tight, chair will be hard to steer.

REMOVAL OF SWING-AWAY FOOT RESTS/LEG RESTS

Release lock by pushing on the front rigging lever. Swing-away
foot rest /leg rest out and sideways. Lift to remove.

ADJUSTING LENGTH OF FOOTREST/LEG REST

When adjusting length of foot rests or leg rests, user should
be sitting in wheelchair with feet on the foot plates. Loosen
bolt on the clamp around support assembly. Raise or lower
foot plate to desired position that will provide maximum
support of thighs. Front rigging should not be so low that
it causes uncomfortable pressure to thighs at front of seat
upholstery. Footrest should not be lower than 2-1/2" from the
ground to ensure clearance.

ADJUSTING/ELEVATING LEG REST

Lift foot plate on leg rest assembly to desired position.
Release leg rest assembly and it will automatically lock into
place. To lower, push out on leg rest lever and lower foot plate
to desired position.

WHEELS

Large rear wheels should be inspected at least once a month
to ensure proper tightness. If wheel wobbles or is loose,
release lock nut and tighten axle bolt slightly. Test for proper
tightness by learning chair to one side and spin adjusted
wheel.

GENERAL CARE

Wipe chrome parts with a clean, soft cloth at least once a
week. All metal parts can be cleaned with auto wax or similar
products. If exposed to moisture, dry immediately. Do not use
an abrasive cleanser that will scratch the finish.
