Operations 5
(1) Close both doors.
(2) Release the parking brake (4-7/4).
(3) Pre-select a gear [(4-8/4) » applies to slow-runners
type "20 km/h" and "25 km/h" «] or [(4-7/1) » applies to fast-
runners type "40 km/h" «].
(4) Pre-select a hydraulic drive step [(4-7/1) » applies to
slow-runners type "20 km/h" and "25 km/h" «].
(5) Select a travel direction (4-7/3).
(6) Depress the drive pedal (4-5/2).
NOTE
- To achieve maximum performance the
combined action of propulsion unit and main
hydraulics is required. It is up to the operator
to to control the available power using the
drive pedal, inching and the manual hydraulic
controls to assign power as required for the
job in hand.
- Travel speed and power are controlled by
depressing the drive pedal only.
- While the vehicle is traveling up a slope, travel
speed is reduced to provide more power, even
if the drive pedal is fully depressed.
- Power and travel speed are equal both in
forward and reverse directions.
ATTENTION
- If the warning indicator for hydraulic oil
temperature (4-8/31) lights up, or an accoustic
signal is given, stop the vehicle immediately
and call in an expert to troubleshoot the
hydraulics and remedy the issue.
- Do not attempt to lock the hydraulic quick
coupling assembly unless an attachment is
fitted.
- Ensure that the engine is idling while coupling
or decoupling an attachment. This ensures
that the insertion or retraction speed of the
locking bolts stays reasonably low thus
preventing leaks.
DANGER
If special tasks necessitate driving with the bucket
arm swiveled, the bucket or the attachment must
be kept close above the wheel and the travel
distance must be kept as short as possible. If
because of rough terrain a wheel is raised off the
ground by the stabilizer equipment, the bucket
arm must be briefly swiveled in the direction of
travel in order to disengage the axle lock.
