CUTTING DECK TILTING AND BLADES SHARPENING
For the cutting deck control and maintenance proceed as follows:
1) Start the engine;
2) Unhook the two red cutting deck blocking levers (fig. 12, ref. A);
3) Tilt the foot rest platform until it is stuck in the corresponding rubber buffers (fig. 13, ref. A);
4) Keep the deck lifting switch pressed (fig. 1, no. 4) until the complete tilting of the cutting deck (fig. 22).
The switch has to be pressed in the direction that approaches the cutting deck to the ground;
5) Release the switch.
6) Turn the engine off.
7) ATTENTION! Connect the security locks as per fig. 23 and remove them only once maintenance
has been carried.
It is not necessary to unhook the PTO belt.
Attention! It is possible to tilt the cutting deck also with the machine's engine turned off. However, we do
not recommend this operation in order to allow the alternator integrated on the engine to compensate the
current absorption during the tilting. When you tilt the cutting deck with running engine the battery will
live longer and the tilting will be quicker.
A blunt blade pulls at the grass giving it an unsightly appearance, the cutting edges of the blades must
therefore be kept sharp at all times. As the blades wear they lose their cutting efficiency and tend to
become unbalanced, causing the lawnmower to vibrate; sharpen all three blades evenly.
When you replace the blades, it is compulsory to replace also the screw and the respective disc spring
(fig. 22, ref. B).
To remove a blade, hold it firmly using safety gloves and unscrew the central screw clockwise. Replace
the blade, make sure to screw the fixing screw tightly.
Caution! Always replace damaged or bent blades; never try to repair them!
ALWAYS USE ORIGINAL BLADES!
Once the maintenance is completed, press the deck lifting switch again (fig. 1, no. 4) to put the cutting
device into the working position. When it is parallel to the ground, lower the mobile foot rest platform (fig.
13, ref. B) and fix the cutting deck with the corresponding red blocking levers (fig. 14, ref. A).
Note: If the red locking levers should be hard to insert:
- check that the red light of the switch behind the machine seat (fig. 17, ref. D) is off. If the light is on, turn
the light switch off.
- check that the cutting deck has finished the tilting phase and is parallel to the ground;
- check that the red blocking levers are well lubricated with grease;
- increase the load on the spring for the cutting deck floating by screwing the adjustment knob (fig. 1, no. 8).
If this does not give a result:
- loosen the four bolts on the tilting hinges (fig. 15, ref. A) and adjust the concentricity of the holes of the
blocking levers until they are inserted. When the operation is completed, screw the tilting hinge bolts tightly.
ADJUSTING THE CUTTING DECK
An even deck is essential for achieving a uniform cut over the whole lawn. With the lawnmower on a flat
surface, check the tyre pressures, check the cutting deck's edge distance from the ground and act on the
tie rod (fig. 16, ref. A) and on the adjusting screw (fig. 15, ref. B) if necessary to put it parallel to the
ground. Before acting on the adjusting screw (fig. 15, ref. B), loosen the corresponding fixing screws (fig.
15, ref. C). If a satisfactory parallel set-up cannot be achieved, contact an Authorised Service Centre.
HOW TO REMOVE THE CUTTING DECK
Never use the machine without the cutting deck. To remove the cutting deck for maintenance follow this
procedure:
1) Press the switch (fig. 17, ref. D) until the warning light lights up.
2) Loosen the PTO belt stretcher by turning the corresponding lever (fig. 17, ref. A) and remove the
belt from the cutting deck pulley.
3) Carry out points 1-2-3 listed in the paragraph "CUTTING DECK TILTING".
4) When the cutting deck frame wheels lift from the ground, stop the tilting and put the cutting height
indicator in position "2" (fig. 2, no. 10).
5) Disconnect the connector of the electrical system (fig. 20, ref. A).
6) Lift the red safety hooks (fig. 18, ref. A).
7) Catch the cutting deck frame frontally and remove it from its place.
Attention! Never unlock the switch (fig. 17, ref. D) when the cutting device is off. The cutting deck fixing
arms could violently hit the upper part of the machine with the risk of damaging things or people close to
the machine.
To connect the cutting device back to the machine:
1) Approach the hinges to the hooks by lifting and setting them into their groove.
