7 – STARTING AND STOPPING
Whenev er y ou set about starting a cold engine, make sure :
• That the gasoline cock “A” is alway s open. The lev er must be
placed towards the outlet pipe.
• That the gasoline has reached the carburetor. If so, by pumping
piston “B”, the gasoline will drop down f rom the hole on the
upper section of carburetor.
• Then, turn the accelerator control lev er placed on the handle-bar
of about ¼.
• Check that the gear-lev er and the mill-control lev er are idle.

8 - OPERATING AND REGULATING THE MACHINE
FUEL INLET
FOR
REPLENISHING
The ref uelling must be alway s perf ormed bef ore starting the work, with cold and
stopped engine, using a f unnel, and in the open air.
If f uel comes out f rom the tank, mov e the machine at once bef ore starting the engine
and dry well the parts wet of gasoline.
We recommend to use alway s a f unnel with a net-f ilter in order to keep back the
possible impurities.
FUEL-TYPE: gasoline-oil mixture 4%
SAFETY LEVER : The motor hoe is prov ided with a red saf ety stop lev er connected
to the clutch lev er (Ref . G)through side blocking push button (Ref . “F”).
The main f unction of this lev er consists in stopping the engine in the moment in which
the hands are remov ed f rom the driv ing-beams.
It’s recommended not to bind the stop-engine lev er “E” to the handle-bar hand-grip.
CLUTCH LEVER : To assure a regular clutch working it is a good rule to check f rom
time to time the play that the clutch-lev er must hav e: (as shown in the picture) the
lev er idle-stroke must be f rom 8 to 10 mm. In the opposite, act on the adjuster (G)
increasing or decreasing the play according to the need.
DRIVING-BEAMS :
Adjustable in height and transv ersally , with possibility of locking in the wished
position. This operation must be carried out by means of the screw-handle (“A”) placed
on the lowest section of driv ing-beams.
SPEED AND MILL CONTROL LEVERS :
The shif ting of speed-lev er (Ref . “I”)must alway s happen under the f ollowing
conditions:
• With engine idling
• With the hand-clutch-lev er (Ref . G) pulled towards the hand-grip.
Any how, nev er f orce the lev er in its shif ting.
ATTENTION: The mills rotation must never occur, when the machine is in reverse speed, an
inner lever-system disengages the mill or the reverse-speed.

SpA RT 80
If this should not occur, apply to a skilled workshop by our concessionary agents.
In the picture, turning lever “A” left the rotary tiller is activated, on the contrary turning it right it is stopped.
POWER TAKE-OFF :
The motor hoe is equipped with a lateral power take of f , which may be
employ ed both with stopped and running machine.
The power take of f and its own couplings are unif ied with most of commercial
fittings.
POWER TAKE-OFF OUTLINE:
Splined 16 UNI 221X120 mm. Working
Turning direction: lef t.
Max. rev . 440 at 5,000 engine/RPM.
MILL BONNET :
The milling-depth may be adjusted as f ollows: f or working on the surf ace,
it’s recommended to keep the saf ety -mill-bonnet lowered.
For a deep working, to sink more in the ground.
For these operations it’s suf f icient to act on the pin f ixing the bonnet “L” and on
adjusting pin “M”.
DIRECTION - JOINTER :
For getting a more regular machine adv ancement it is suf f icient to operate the
adjustable direction-jointer.
When working on sof t ground, it is required to keep the spur up, to help the
machine adv ancement.
On solid ground it’s right to keep the jointer down, so that sinking in the earth it
prev ents a too quick machine adv ancement.
For this adjustment, act on the pin “N” f ixing the jointer.
The machine presented in this manual has been designed to be used only in
agriculture and especially f or ground milling.
Any dif f erent use is considered contrary to its proper use.

10 - MAINTENANCE AND LUBRICATION
PLUG-CONTROL :
From time to time it’s necessary to check the plug wear-lev el and the
electrodes-distance, which must be of 0.5 mm , as shown in the near drawing.
AIR FILTER CLEANING :
This operation must be perf ormed regularly in the f ollowing way :
• clean the f ilter externally , so to av oid that some earth f alls inside during the
disassembling.
• Loose the clips “P”, remov e the oil-cup “Q”, take away the f ilter-element “R”
and wash caref ully the dif f erent parts with gasoline oil.
• Fill the cup with new oil till reaching the lev el, as pointed out in the picture.
OIL INLET BLEED :
Ev ery component of the gear-box and transmission is in oil-bath. It’s
necessary to check f rom time to time the oil-lev el through screw “S” and f ill it up
again, if required, through the v ent plug “T”.
USE ONLY OIL FOR TRANSMISSION SAE 30
on
oil
FRONT-WHEEL OIL LEVEL PLUG :
Check f rom time to time the oil lev el on the f ront wheel through plug “U”, placed
one side, as shown in the picture. For a perf ect machine ef f iciency , a good
maintenance and a perf ect lubrication are necessary .
Check that air f ilter is clean, in case of oil bath f ilter check lev el ev ery 8-10
operating hours or ev en more f requently when working in dusty grounds. Use motor
to restore oil lev el and clean the cup bef ore f illing it.
GEARBOX Check oil lev el ev ery 50 operating hours remov ing the cap on the
gearbox sump keeping the machine in horizontal position.
If necessary add SAE 30 oil. It is adv isable to replace oil at least ev ery 100

11 - END-OF-SEASON MAINTENANCE
OIL DRAG PLUG :
For whatev er mechanical repair in the ear-box or in the mill-descent, it’s
necessary to remov e the oil.
To make the transmission empty , unscrew the plug “V” placed in the lowest
section of the gear-box.
Before parking the machine:
• wash it accurately with gas oil,
• empty the carburetor tank and clean or replace air f ilter,
• lubricate and grease all articulated joints and gears,
• replace or repair possible worn parts,
• lubricate cy linder with motor oil through the spark plug hole, pull the start-up
cord so that the piston makes some strokes
• Park the machine in a dry place with wheels on wood tables or ev en better with wheels up f rom the f loor.
12 - POSSIBLE PROBLEMS AND SOLUTIONS
Possible problems that can be solv ed by the machine operator:
MOTOR - The motor does not start; check that:
• the gasoline in the tank is more then half .
• the gasoline cock is open
• if the motor is cold , the starter lev er is pulled
• the gasoline reaches the carburetor
• the bleed on the tank cap is not clogged
• carburetor jets are not clogged, if necessary , clean
them with air jet
• the spark plug sparks, in order to carry out this check
operation unscrew the spark plug; connect it to the power
supply cable, place the spark plug earthed metal part
(motor cy linder) and make the motor pulley turn as in the
start-up phase. If electrodes do not spark, check the
supply cable junctions, and if this does not solv e y our
problems, replace the spark plug with one of the same
ty pe. If ev en this time y ou should not obtain positiv e
results, the def ect concerns the electric plant (points,
condenser, coil etc.)In this case it is adv isable to contact
the nearest serv ice (according to the motor assembled on
the machine).
