SECTION 7—GENERAL GUIDELINES
WARNING
A pinch point exists between walking beam/head tube cap and telescoping tube
when the wheelchair is at the lowest seat to floor height.
Pinch point may occur when returning the tilted seat to the full upright position.
Make sure the hands and body of the occupant, attendants and bystanders are clear
of all pinch points before returning the tilted seat to the full upright position.
Before performing any maintenance, adjustments or service, ALWAYS turn the
wheelchair power Off, otherwise injury or damage may result.
DO NOT install the spring assist assembly onto M71 wheelchairs. This option is for
M91 and TDX wheelchairs only. Otherwise, injury or damage may occur.
TRANSPORT READY PACKAGES ARE NOT RETROFITTABLE TO EXISTING
MODELS AND ARE NOT FIELD SERVICEABLE.
TDX Wheelchairs with TRBKTS Only - Battery support brackets MUST be installed
at all times. Refer to TDX Batteries on page 171.
Cables MUST be routed and secured properly to ensure that the cables DO NOT
become entangled and damaged during normal operation of seating system.
Cables MUST be secured to the wheelchair frame and/or base with tie-wraps after
servicing is complete. Failure to follow the warnings and instructions listed below
will result in injury to the users, attendants and/or bystanders and/or damage to the
wheelchair.
Cables MUST be secured so there are no loops of excess cable extending away from
the wheelchair. Bundle all excess cable together and secure with a tie-wrap. It may
also be necessary to secure these bundles to the frame and/or base.
ALWAYS test all wheelchair functions after securing the cables to ensure cables
DO NOT get pinched or crushed during operation of the wheelchair.
M71 Wheelchairs Only - DO NOT adjust the seat height. Adjusting the seat height
from the factory setting will make the wheelchair unstable and injury or damage
may occur. The M71 wheelchair seat should only be mounted in mounting hole B
(FIGURE 15.7 on page 91).
M91 Wheelchairs Only - DO NOT use Mounting Hole A. This mounting hole
combination will cause interference between the front riggings and/or the seat
frame and wheelchair base. Users over 250 lbs. MUST use Mounting Hole B.
Mounting Holes C, D and E MUST only be used for users under 250 lbs. See
FIGURE 15.7 on page 91.
DO NOT adjust rear seat posts higher than front seat posts.
All seat brackets or seat posts MUST be adjusted to the same height.
DO NOT overtighten hardware attaching to the frame. This could cause damage to
the frame tubing.
