SECTION 1—GENERAL GUIDELINES

Make sure detent balls of the quick‐release pin are fully released before operating the
wheelchair.

Keep detent balls clean.

When determining the depth of the telescoping front frame tubes, make sure the rear of
the footrests do not interfere with the movement of the front casters. Otherwise damage
to the wheelchair may result or may impede proper operation.

Before attempting to transfer in or out of the wheelchair, every precaution should be
taken to reduce the gap distance. Turn both casters parallel to the object you are
transferring onto. Also be certain the power is Off and wheel locks are engaged to prevent
the wheels from moving.

DO NOT adjust the rear seat posts higher than the front seat posts.

Before performing any maintenance, adjustment or service verify that On/Off switch on
the joystick is in the Off position.

ALWAYS wear your seat positioning strap. The seat positioning strap is a positioning belt
only. It is not designed for use as a safety device withstanding high stress loads such as
auto or aircraft safety belts. If signs of wear appear, belt must be replaced IMMEDIATELY.

With regards to seat/chest positioning straps ‐ it is the obligation of the DME dealer,
therapists and other healthcare professionals to determine if a seat/chest positioning strap
is required to ensure the safe operation of this equipment by the user. Serious injury can
occur in the event of a fall from a wheelchair.

Avoid storing or using the wheelchair near open flame or combustible products. Serious
injury or damage to property may result.

Batteries

The warranty and performance specifications contained in this manual are based on the
use of deep cycle gel cell batteries. Invacare strongly recommends their use as the power
source for this unit.

Carefully read battery/battery charger information prior to installing, servicing or
operating your wheelchair.

DO NOT remove fuse or mounting hardware from POSITIVE (+) RED battery cable/
mounting screw.

All battery terminal covers (two on the front battery and two on the rear battery) MUST
be installed prior to use.

The use of rubber gloves is recommended when working with batteries.

Some battery manufacturers mold a carrying strap and/or hold down flanges directly into
the battery case. Batteries that interfere with the battery box cannot be used for these
applications. Attempting to “wedge” a battery into a battery box may damage the box,
the battery and/or be a fire hazard, resulting in serious injury or further damage to
property.
