Handlebar Adjustment; Differential Lock; Finishing Work - Grillo G131 Manuel D'utilisation

Translation of the original instructions
CAUTION: for safety reasons on all Grillo walking tractors it is not possible to engage
reverse gear when the rotary tiller is on. The PTO must always be disengaged before
engaging the reverse gear. IN CASE OF DANGER RELEASE THE RED CLUTCH LEVER (fig.
1, n. 1) BOTH THE MACHINE AND THE ROTARY TILLER WILL IMMEDIATELY STOP.

HANDLEBAR ADJUSTMENT

To adjust the height of the handlebar unlock the appropriate lever (fig. 1, n. 11), raise or lower the
handlebar and then release the lever to lock its position. To turn the handlebar use the lever (fig. 1,
n. 2), turn the handlebar to right or to the left and then release the lever to lock its position.

DIFFERENTIAL LOCK

G131 is equipped with the differential on the wheels axle. A black lever (fig. 1, n. 12) is placed on
the left side of the handlebar, that is used to lock (by turning the lever downwards) and unlock (by
turning the lever upwards) the differential. The differential is normally unlocked when working to
make steering easier. It is recommended to engage the differential lock when working on slopes
and on uneven soils to improve the machine adherence to the ground.
WHEEL AXLE LOCK
The walking tractor can be towed by hand by unlocking the transmission wheel axle. To unlock the
wheel axle turn the lever located at the base of the handlebar (fig. 4, n. 19 - follow the instructions
on the label placed beside the lever). Once the machine has been towed, bring the lever back into
working position.
ATTENTION: It is highly dangerous to work on slopes with the wheel axle unlocked.
HOW TO SWITCH THE DIESEL ENGINE OFF
Press the switch-off lever located on the left side of the handlebar (fig. 1, n. 22).
IMPORTANT: once the engine has been switched off, turn the starting key anti-clockwise to
disconnect the battery (fig. 2, n. 23). Should the ignition key remain ON with the engine off, the
battery will run down.

FINISHING WORK

Once work has been finished, switch the engine off, remove the ignition key, set the gear lever in
idle position and disengage the PTO.
ATTENTION: on slopes never leave the machine in idle position. If it is necessary to park the
machine on slopes always engage the 1 st gear (fig. 1, n. 13).
ATTENTION: never leave the machine unguarded or in a place where children or inexperienced
people could have easy access to it.
TIPS FOR EFFICIENT USE
1) Never leave the machine exposed to bad weather condition.
2) Never force the reverse gear: If the gear does not engage immediately, do not force the lever
but press and release it repeatedly until the gear engages.
3) Never strain the engine: if smoke comes out of the exhaust, slow down.
4) Adjust the central knife (fig. 20) according to the kind of soil (hard/soft).
TROUBLESHOOTING
The following is a list of inconveniences which may occur during the use of the walking tractor,
which the operator himself can remedy.
1) if the diesel engine does not start check:
– that the fuel tank vent hole is not blocked;
– that the fuel tank is at least half full.
2) If the engine is on but the machine does not move forward:
- check that the wheel axle lever (fig. 4, n. 19) is in working position.
- check that the gear is engaged.
