4. Accelerator lever
This lever is used to control the engine speed and power.
(a) Minimum: push the lever completely forward.
(b) Maximum: pull the lever completely backward.
Use the accelerator with care, especially when the machine is un-
der strain or is working in difficult conditions. Avoiding useless ac-
celerations means reducing consumption and extending the
service life of both the engine and the machine.
5. Blade/adjustable track gauge lever (if provided)
WARNING
q
Narrow the track gauge only when it is necessary to travel
or to carry out digging operations in small spaces. In any
other condition, always select the wide track gauge.
q
Avoid adjusting the track gauge when the machine is work-
ing on a slope. This may affect the lateral stability of the
machine.
q
Widen or narrow the track gauge with the machine resting
on a firm and level surface and the tracks slightly raised
from the ground, in order to avoid damaging the tracks and
the hydraulic motors.
This lever is used to control the movements of the blade or to ad-
just the track gauge, depending on the position of the switch (see
"3.2.2 pos: 5. Blade/adjustable track gauge selection switch (if
provided)").
Blade
(a) Lower
(b) Lift
Adjustable track gauge
(a) Narrow track gauge
(b) Wide track gauge
NOTE
q
When carrying out digging operations that require the blade to be used for more than one hour without interrup-
tion, pay attention to the coolant temperature, since this may increase excessively.
q
Before using the lever, check the position of the blade/adjustable track gauge switch.
