6.14 Differential locks
Gremo1050F4 Instruction manual
For safety reasons, working speed is deactivated when the
levers are not active and the chair is turned towards the
door or forwards (normal position).
For working speed settings, see 5.4 Engine window , page
75.
6.14 Differential locks
Fig. 106 Controls, differential lock
The differential locks are operated with the buttons (1) and
(2) on the left armrest panel. The button (1) controls the
differential lock on the front carriage (front axle) and the
button (2) controls the differential lock on the rear carriage
(rear axle). The front and rear differential locks are
operated independently and give a complete locking of the
differentials while the buttons are pushed.
The indicator lamps (3) and (4) are yellow when the
differential locks are engaged.
In the middle of GreControl's main window, a symbol
indicating when the differential locks are engaged is also
displayed, see 5.3.2
Instrumentation , page 72.
Activation of the differential locks can be done while the
machine moves without pulling heavily, but we recommend
that you stop first.
WARNING
The differential locks must not be activated or de-
activated while the machine is turning!
WARNING
Never operate the differential locks when a wheel is
skidding! You could damage the differentials!
NOTICE
The use of the differential locks means that a wheel or a
bogie may suddenly get the complete traction force if
this wheel or bogie suddenly gets a hold while the other
wheels are skidding. Therefore you should use the
differential locks with sound judgement, especially if you
have fitted bogie tracks.
You will spare the machine if you activate the front and
rear differential locks simultaneously and, if possible, avoid
steering the machine while the differential locks are active.
Also try to keep low engine revs. It spares the transmission
and gives better traction
