MAINTENANCE MANUAL
3.6.13.3 Check of the service brake
This test veries the function of the service brake. After activa-
ting the service brake, the hydraulic components of the machi-
ne drive adjust to stop the machine. The service brake can be
controlled at any time. Using the service brake does not activate
the parking brake (P).
Check that the area in front of and behind the machine is
empty and that there are no persons or obstacles there!
Ensure a suitable safe distance in front of the machine,
behind the machine as well as on its sides.
Perform the test on a level and solid surface. If the test
is performed on a slope, the machine may start moving
due to leaking hydraulics even though the service brake
is in order!
Procedure
Place the machine on a at and solid surface.
Sit in the driver’s position and start the engine according to
Chapter 2.7.1.
Move o by setting the travel control (11) to the forward travel
position “F”.
Set the travel control to the neutral position “N”.
The machine will stop and the parking brake will not activate.
To move o again or control the brake during braking, move the
travel control (11) back to the forward travel position “F”.
If the machine does not stop, activate the emergency brake, se-
cure the machine against spontaneous movement using wed-
ges on a level and solid surface and contact service.
Activation of the emergency brake will cause a high me-
chanical and hydraulic load of the machine. Always test
the parking brake after activating the emergency brake
while driving.
