Tipping Tubes

Tipping Tubes (Fig. 4.0).
Tipping tubes are used by attendants to tip a wheelchair
over an obstacle. Simply step on the tube to push a
wheel chair, for example, over a curb or step,
NOTE:
Sunrise Medical strongly reccommends the use of a step
tube on any model where attendant use is the predomi-
nant intended use, as damage to the backposts may
occur if you pull back on them to tip the wheelchair

Wheel Locks

Wheel Locks (Fig. 4.1 + 4.2)
Your wheelchair is equipped with two wheel locks.
They are applied directly against the tires. To engage,
press both wheel-lock levers forward against the stops
(Fig.4.1). To release the wheel, pull the levers back to
their original pos i tions.
Braking power will decrease with:
• Worn tire tread
• Tire pressure that is too low
• Wet tires
• Improperly adjusted wheel locks.
The wheel locks have not been designed to be used as
brakes for a moving wheelchair. The wheel locks should
therefore never be used to brake a moving wheelchair.
Always use the handrims for brak ing. Make sure that the
interval between the tires and wheel locks complies with
given specifications (Fig.4.1). To readjust, loosen screw
(1) and set the appro priate interval. Tighten screw (see
the page on torque).
CAUTION!
After each adjustment of the rear wheels, check the
interval to the wheel locks and readjust if necessary.
Extension for the Brake Lever (Fig. 4.3)
The extension for the brake lever can be removed or
folded down. The longer lever helps to minimize the effort
needed to set the wheel locks, (Fig.4.3).
CAUTION!
Mounting the wheel lock too close toward the wheel will
result in a higher effort to operate. This might cause the
brake lever extension to break!
Leaning onto the brake lever extension while transferring
will cause the lever to break! Splashing water from tires
might cause the wheel lock to malfunction.
