5.9 Manual Override
If for whatever reason the stretcher battery charge has been fully
depleted and unable to recharge, the actuator manual override
system can be used to operate the stretcher and allow the
stretcher still to be lowered/raised and loaded/unloaded without
power. This does require some additional manual handing,
especially when raising the stretcher or loading the stretcher so
use additional trained helpers as needed. See "Using Additional
Help" on page 7.
Note: The manual override handle (Q) will not function unless
the weight has been lifted off the leg locking mechanism. This is
a safety feature to help prevent accidental retracting of the legs.
EXTENDING OR RETRACTING USING MANUAL
1.
Both Operators/Trained Helpers: Stand at opposite ends
of the stretcher and hold the main frame with an underhand
grip (palms up).
2.
Both Operators/Trained Helpers: Lift the stretcher slightly
to lift the weight off the leg locking mechanism.
3.
Control-End Operator: Pull the manual override handle only
long enough to make the position change.
4.
Both Operators/Trained Helpers: Together, raise or lower
the stretcher to the desired height, then hold the stretcher at
that position (Figure (26).
5.
Control-End Operator: Release the manual override handle
to lock the stretcher at the desired height.
6.
Both Operators/Trained Helpers: Slowly lower your hands
to confirm the stretcher has stabilized at the new position.

OVERRIDE
VIPER
The manual backup mode is not intended for routine
handling. Use it only in case of electronic failure and only
for necessary actions.
If the ambulance is parked on an uneven surface, the
operators (and any helpers) may need to extend or retract the
legs from the user-set loading height to allow the stretcher to
roll into the ambulance.
