DRIVE Assist Handle Calibration
When the stretcher is switched on, the system status indicator (item 2, Fig. 13) will flash
for 1-3 seconds indicating that the
DRIVE
handles are calibrating. The indicator will turn
solid green when calibration is successful and another short beep will sound; the
DRIVE
handles are now active. If the system status indicator continues to flash, calibration has
not been successful.
CHECK: If the backrest is below 35°, the fold-away handles must be deployed in an
upright position ready for pushing for calibration to be successful; see Section 15, ‘Using
the Fold-away Handles’. If the handles are folded away, then calibration will not be
possible, and the system status indicator will continue to flash. The fold-away handles
may be stored if the backrest is above 35°, as this will not affect calibration for the fixed
handles.
NOTE:
Do not place hands on the
DRIVE
handles immediately after switching on the
system. It is important the
DRIVE
handles are not touched during calibration, as
this will delay, or prevent, successful calibration.

Using DRIVE Assist
After successful calibration,
DRIVE
is now active. If the backrest angle is below 35°, the
fold-away push handles will be active. If the backrest angle is above 35°, the fixed push
handles will be active. As the backrest is articulated through 35° the
DRIVE
handles will
automatically switch from active to non-active, and vice-versa.
Firstly, make sure the
DRIVE
wheel is engaged.
Driving: Push positively on the
DRIVE
handles and the stretcher will begin to move
forwards. Push harder and the stretcher will move more quickly. Pull back on the
DRIVE
handles to slow, stop, or reverse, the stretcher. The stretcher is restricted to a
maximum speed of 6km/hr.
Driving up a slope: Push the
DRIVE
handles fully forward, and walk at the pace of
the stretcher. Pushing harder will result in unnecessary physical exertion, and the
speed of travel will not be increased.
Driving down a slope: As you approach a downhill slope, pull back gently on the
DRIVE
handles to decrease the stretcher speed. As you walk down the slope,
continue to pull back gently on the
DRIVE
handles to descend the slope under
control.
A full battery provides more than 20km (12.4 miles) of
DRIVE
assistance. Note; this
figure is a guide only, and will vary depending upon a number of conditions, i.e.;
patient weights, the number and severity of inclines, battery age, etc.
NOTES:
If you attempt to
DRIVE
using the non-active handles, the ‘READ
INSTRUCTIONS’ indicator will flash amber and a beep will sound (item 3, see
Fig. 13).
The stretcher will not
DRIVE
if the brakes are engaged, and the ‘READ
INSTRUCTIONS’ indicator will flash amber and a beep will sound.
The stretcher will not
DRIVE
if the mains charging lead is still connected.
The stretcher will not
DRIVE
if the wheel is not engaged, see Section 11,
‘Using the Steering Pedal’.
CAUTION: The maximum slope angle for
DRIVE
assist is 6°; exceeding this
angle could result in damage to the stretcher or the fabric of the building.
CAUTION: Ensure the mains charging lead is disconnected before attempting
to move the stretcher; failure to do so could result in damage to the stretcher
or the fabric of the building.
