Operation

DANGER
Risk of burns, risk of crushing!
Only use the vehicle if all panels are attached.

WARNING
Risk of damage due to overheated hydraulic oil or over-
heated motor!
In case of excessive hydraulic oil temperature or exces-

sive cooling water temperature, set the motor speed to
idling (do not switch off the motor) and perform the
measures described in Chapter "Faults".
Risk of damage due to missing lubrication!
If the warning light for the oil pressure lights up during

operation, immediately switch off the motor and rectify
the fault.
DANGER
Long hours of using the appliance can cause circulation
problems in the hands on account of vibrations.
6.1

Drive mode

It is not possible to specify a generally valid operation time,
since this depends on several factors:
Proneness to blood circulation deficiencies (cold, numb
–
fingers).
Low ambient temperature. Wear warm gloves to pro-
–
tect hands.
A firm grip impedes blood circulation.
–
Continuous operation is worse than an operation inter-
–
rupted by pauses.
In case of regular, long-term operation of the device and in
case of repeated occurrence of the symptoms (e.g. cold,
numb fingers) please consult a physician.

6.1.1 Drive pedal
The accelerator pedal can be used to drive forwards and
backwards.
If the accelerator pedal is released, the hydrostatic drive of
the vehicle is delayed or stopped.
ATTENTION
Always press the accelerator pedal carefully and slowly.
Do not jerkily change from reverse to forward drive or vice
versa.
6.1.2 Parking brake
The parking brake acts on the rear wheels and uses a
sheathed cable. If the braking power starts to decline, it
can be readjusted on the lever with a setting screw. The
brake shoes should be replaced only by Customer Ser-
vice.
ATTENTION
Check the braking effect of the parking brake now and
then; the braking effect is OK if the vehicle can be stopped
on an incline of 16°.
6.1.3 Brake pedal
The brake pedal activates the brake system of the rear
wheels. The correct setting of the brakes takes place auto-
matically, no adjustment work is required.
Actuation takes place hydraulically, therefore always make
sure that there is a sufficient amount of brake fluid in the
storage tank.
