Karman Healthcare S-Ergo 105(KM-1500?3) Owner's Manual page 22

Karma always recommends that the user be transferred into car seat with a
safety belt or harness while in a transport.
SUGGESTION:
Remember that the best solution is always to move the user from the wheelchair
into a normal car seat.
4.5.1 Before use
CAUTION:
If the back angle of the wheelchair is adjustable, do make sure that the
wheelchair backrest should be positioned as close as possible to 90
Please detach all easily removable accessories from the wheelchair and
store them in a safe place where they cannot move around and become a
safety hazard.
A four point tie-down system should tightly fasten the lower wheelchair frame (hook
mark ) to the transport vehicle.
An occupant restraint system using both a pelvis and harness must also be
fastened to the transport vehicle to insure user safety. Again, please refer
to the restraint system's instructions.
The attendant / transporter must double-check all fastening points for proper
connection and tightness to assure the wheelchair user's safety. The
attendant / transporter must be fully aware of the fastening system's usage
and its weight limitations.

(front/rear wheels, hand rims, caster, footrests, armrests, anti-tippers etc.).

cross them and trip yourself up.
