Maintenance And Lubrication - Grillo BEE FLY Uso Y Mantenimiento

MOWING POSITION
Use the 4 pins (fig. 1 no. 10) to adjust the cutting height.
When working on terrain which is rough, has bumps or humps, it is best to use the deck in the highest cutting position
to avoid impact with the blade.
SLOPING GROUND
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, use the hydraulic control to raise the deck slightly 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.
SAFETY DEVICE TRIGGERING
Always remember that the engine stops each time:
– the operator gets up from the seat.
In addition, the engine will not start if:
– the blades are not engaged;
– there is no one seated at the controls;
– the speed presetting lever is not in the stop position.
CAUTION!
While moving from one location to another do not travel with the cutting deck raised. Only raise the deck hydraulic
lifter to avoid obstacles, climb onto pavements or up kerbs. The deck hydraulic raiser is fitted with a hydraulic jack
that makes sure the deck goes down again after a few minutes.
Do not increase the pressure in the hydraulic circuit to more than 130 bar; this could damage the hydraulic pump.
To adjust the hydraulic pressure turn the screw with lock nut located on the distributor.
This operation is to be carried out by an authorised service centre.

MAINTENANCE AND LUBRICATION

CAUTION!
Remove the ignition key and disconnect the spark plugs (petrol version) before carrying out any cleaning,
maintenance or repairs. Always wear suitable working clothes and safety gloves.
LUBRICATION
Never dispose of used oil, petrol or any other type of pollutant in the environment!
Proper maintenance and correct lubrication help to keep the mower working perfectly.
ENGINE
For the lubrication intervals follow the directions given in the engine manual; it is in any case indispensable to
change the oil after the first 20-30 working hours.
For the petrol engine use SAE 30 oil, 1.4 lt. without filter, 1.6 lt. with filter (fig. 9).
For the diesel engine use SAE 10 W 30 oil, 2.9 lt. (fig. 10).
Change the oil filter (fig. 11 - petrol engine; fig. 12 - diesel engine).
The first precaution to be taken is that the engine is maintained correctly with a clean air filter, cooling fins, and heads
and that the engine oil is up to the level.
Keep the engine compartment clean, using a vacuum cleaner if possible.
Check the air filter every 4 hours or even more frequently if in dusty conditions.
Clean the air inlet grill for cooling the engine.
In order not to reduce the air needed to cool the radiator, the vents outside and inside the engine must
always be kept clear. Make sure the radiator is always kept clear.
REDUCTION-GEARS ON WHEEL
Check the oil level every 200 hours by unscrewing the cap, fig. 13; if necessary, add AGIP ROTRA MP 85 W 90
oil (international equivalent API GL5 or US MIL-L-2105D; 0.7 lt. each), change every 1.000 hours.
