Climber 7.10 / Translation of the original instructions
Lubricate the bushing in the belt stretcher of cutting deck- engine belt (fig. 16/A).
AIR FILTER
Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig. 8).
CHECKING THE BLADES AND CUTTING DECK
A blunt blade tears the grass, therefore the cutting edges of both blades must be sharpened. To remove
a blade, take hold of it firmly, wearing work gloves, and unscrew the central screw (3 fig. 9),
remembering that the screw has a right-hand thread. Sharpen both cutting edges using a medium-grain
grinding wheel and check that the blade is balanced by standing it on a round bar inserted in the central
hole.
Fit the two cutting blades following the diagram in fig. 9.
CAUTION!
Tighten the fixing screw (3 fig. 9) firmly.
Always replace damaged or crooked blades; never attempt to repair them! When fitting, always follow
the diagram fig. 9.
ALWAYS USE ORIGINAL BLADES! If they are worn they can be turned round since they have two
cutting edges. Always check that the blade bolts are not worn or damaged.
ADJUSTING THE CUTTING DECK
Levelness of the cutting deck is essential in order to obtain an evenly mown lawn.
Park the mower on a flat surface and check that the tyre pressure is correct. Adjust the 4 adjustment
devices (fig. 17 – 17A), so that the edge of the cutting plate is at the same distance from the floor, 110
mm, on both sides (with the operator sitting on board and the cutting deck in the lowest position, fig.
18/A).
If you are unable to level off the deck, contact an Authorised Grillo After-Sales Service Centre.
BLADE - ENGINE BELT
If the belt becomes twisted or comes off, make all the checks and adjustments illustrated in fig. 18/A,
keeping the deck at the lowest position.
Take care when positioning the belt guides; move them towards the belt, checking the deck at the
various height settings (A, fig 19).
HYDROSTATIC AXLE - ENGINE BELTS
These belts are self-adjusting and do not require any adjustment. Simply check the spring tension. To
replace the belts, release the tension spring (fig. 21).
BLADE ROTATION
Rotation is started and stopped using the switch 4 in fig. 1.
When rotation is engaged, the engine must be running at medium rpm and the machine must not be in
the grass for cutting. Never start the blades with the engine at maximum rpm.
The machine is equipped with an electromagnetic clutch which also brakes the blade during
disengagement.
The blades are also disengaged automatically when the cutting height adjuster lever is moved to the
highest position.
CAUTION!!!
To reactivate the blade, put the lever no. 8 fig. 2 into the desired cut position and
press the PTO button (fig. 1 n. 4)
The blade must stop within 5 seconds, if this is not the case, adjust the 3 nuts of the electromagnetic
clutch, placing a 0.3 mm feeler gauge under the brake plate.
N.B. This operation must be carried out by an authorized after-sales service centre.
