Safety Devices - Grillo FD900 4WD Manuel D'utilisation

MOWING POSITIONS
Use the button (fig. 1 n° 12) to adjust the cutting height. When working on irregular ground, with bumps or humps, it
is best to use the deck in the highest cutting position to avoid impact with the blade. Important: During work the deck
lifting button has to be kept in the «floating» position (fig. 1, n. 7).
SLOPES
Steep ground should be tackled in an up-and-down movement, being very careful at direction changes that the
wheels uphill do not meet any obstacles (stones, branches, roots, etc.) which could cause loss of control over the
machine. If the drive wheels tend to slip when driving uphill, use the hydraulic control to slightly raise the deck so
that more weight is exerted on the drive wheels, therefore giving more traction. Evaluate the various conditions and
be careful in the presence of damp ground and wet grass because this could cause the mower to slide. When going
downhill, start off at a slow speed and avoid driving over dry or cut grass because the wheels could lose their grip.
The differential lock (fig. 1 n° 25) automatically engages when driving downhill preventing the wheels from slipping if
the operators changes direction or when loading the lawnmower onto a truck/lorry in reverse using ramps. Under
normal working conditions, do not engage the differential lock (fig. 1 n° 25).
Do not run any risk, check the ground carefully and if you do not feel safe, avoid strong slopes and do not exceed
the speed-limits, which are imposed by your country laws and written also in this manual (max. 14° or 25%).

SAFETY DEVICES

Always remember that the engine stops each time when:
- the operator gets up from the seat and the parking brake is disengaged.
In addition, the engine will not start if:
- the PTO switch is engaged;
- if there is no one seated on the driving seat and the parking brake is disengaged.
- the forward and reverse pedals are not in the "stop" position;
- the grass catcher is not completely lowered.
Attention! When the parking brake is engaged, it is possible to leave the driving seat with the engine on, if the
blades are disengaged.
ROLL-BAR
CAUTION: To avoid injury or death from roll-over keep the roll-bar in the raised lock position and use the
seat belt.
Ensure that the seat is secured with the seat latch.
There is no roll-over protection when the roll bar is in the down position.
- Do not operate the machine on uneven ground or on a hill side with the roll-bar in the down position.
- Lower the roll-bar only when absolutely necessary.
- Do not wear the seat belt when the roll-bar is in the down position.
- Drive slowly and carefully.
- Raise the roll-bar as soon as clearance permits.
- Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any
objects and do not contact them.
To lower the roll-bar follow the procedure described below:
- Park the machine on a level surface.
- Disengage the PTO, lower the mower deck, and engage the parking brake.
- Shut off the engine and remove the key.
- Tilt the seat forward (fig. 14C).
- Remove the knob pins from the roll-bar (fig.14A).
- Lower the roll-bar and secure it in place with the knob pins (fig. 14D/E).
- Tilt the seat back.
Important: Lower the roll-bar only when absolutely necessary.
To raise the roll-bar follow the procedure described below:
- Park the machine on a level surface.
- Disengage the PTO, lower the mower deck, and engage the parking brake.
- Shut off the engine and remove the key.
- Tilt the seat forward (fig. 15C).
- Remove the knob pins from the roll-bar (fig.15A).
- Raise the roll-bar and secure it in place with the knob pins (fig. 15E).
- Tilt the seat back (fig. 15F).
