3.12 Electric starter
Two-wheel tractors, in accordance with type motor, can be supplied with an electric starter, on request. In this instance, start the engine as follows:
ATTENTION: battery electrolyte consists of diluted sulphuric acid which can cause bad turns. Avoid contact with skin, eyes and clothing. Do not smoke or bring sparks or flames near to it. Always fill in a well ventilated environment.
For diesel engines: the battery to be installed is 12V 33/ 35Ah (dimensions 232x130x167 mm).
For gasoline engines: the battery to be installed is 12V 14/ 16Ah (dimensions 160x90x161 mm).
Prepare engine for starting as per the instructions in the engine manual; move the red lever B (fig.1 page 27) to the I (ON) position.
Insert key and turn to the right; release the start key once the engine is running.
To stop the engine release the red lever B to the 0 (STOP) position and extract key.
MAINTENANCE: check the liquid level in the battery periodically.
The battery tends to discharge itself if the machine is not used frequently and so the machine should never be left uncharged; recharge it periodically using the electric battery chargers provided.

MACHINE ASS EMBLY

After removing the machine from its box, open the tool kit and follow the assembly instructions detailed below.
Wheels: make attention that the arrows of tread design is directed towards the engine, for two-wheel tractors. Inflating pressure is 1.2 bar (see table 1 page 19).
Carefully read the instructions related to the engine.
ATTENTION: if the engine is fitted with an oil-bath air filter, fill up to the indicated level with correct quantity and quality.
Check that all screws and nuts are well tightened, in particular those fixing the implement to the machine.
ATTENTION: when installing the (heavy-duty) cupped conical washers, the correct orientation must be observed  (as indicated in fig.3 page 16): if mounted upside down, the coupling worsens, compromising the tightness of the nuts and bolts, which tend to become loose very easily, especially if the organs are subjected to vibrations.

IMPLEMENT ASSEMBLY

6.1 For two-wheel tractors 710, 730, 728, 738, 739, 740, 749
Implements are mounted directly to the flange A (fig.12) or fitting between the attachment the quick hitch C (fig.13).
For the scheme of the flange, please refer to figure 14.
6.2 For two-wheel tractor 750
Implements are applied directly to shank A (fig.15). All im- plements are mounted through the interposition of bushing C (fig.16), allowing us to obtain the standard 3-bolt flange shown in fig.17/1. The attachment and detachment of the device are obtained by enabling knob R (fig.16); the device is locked by turning the knob clockwise; the device is free to be detached by turning the knob anti-clockwise. It’s ne- cessary that nuts D (fig.13-16) which fasten the implement and the bushing are well tightened.
To mount to the two-wheel tractors the cutter bar, the lawnmower, the snow thrower, etc. it’s necessary to turn the handlebar of 180° and, for 750, use the bushing for rapid adjustment. Before making that, you must release the speed D (fig.2/a) and PTO control rods E from supports; pull lever for handlebar steering column position H (fig.1/a-1/b) and turn the handlebar in counter-clockwise direction.ROTATION: RIGHT

ROTATION: RIGHT

Release the lever H after choosing the ideal position of the handlebar. After turning the handlebar, rods must be inserted again into the supports. If you turn the handlebar of 180° you get two or three for- ward speeds, that driving lever L (fig.1/a) on the handlebar, become reverse speeds. The two-wheel tractor 710 has one backward gear that can be enabled using the gear lever D (fig.2/a).
6.3 PTO
It is a front locking 3-teeth implement. It rotates right, independently from the gear, and depending on the motor speed (990 rev/1’ at 3600 rev/1’ of the motor or 825 rev/1′ at 3000 rev/1′). The PTO must be enabled/disabled by always using the clutch (C fig.16). For the scheme and the flange dimensions, please refer to figure 14 and 17/1.

CHECKS BEFORE STARTING

THE MACHINE
7.1. Motor oil
Check oil level, following the instructions in the engine ope- rating manual. Should the oil spill off, use the quality and density as prescribed.

Attention: never exceed the maximum oil level established by the manufacturer, in special way for engines.
7.2. Transmission oil
Check oil level in the gearbox through oil plug C (fig.18), verify that the level is between the two grooves 1 and 2. If top-up is required, add  BCS oil PowerLube W7 SAE80W-90 (rif. API GL-5) for hydromechanical drive.
7.3. Fuel
Fill tank with fuel using a funnel with a mesh filter to eliminate impurities. Never fill the tank whilst engine is running. After having performed these operations the machine is ready to be started.

INSTRUCTIONS FOR USE

8.1 Operator training
The machine was designed to work land, it is strictly forbid- den to use it for other purposes (transporting persons, as a trailer, any type of racing, etc.), it must neither be changed nor tampered with, the safety devices should be kept in one piece and in good working order.
Warning! Do not put your hands or feet under the equipment or on the moving or rotating parts.
Prior to using the machine, it is required that you fami- liarize yourself with the controls. Learn how to turn off the engine safely and quickly. Read the safety warnings.
The machine must not be used by those under the age of 16 years. Do not transport passengers. Do not use in the vicinity of ditches or piers that may give way under the weight of the machine.
Hide the ignition key around children.

Transmission movement (transmission and PTO) comes from using the clutch lever (C fig.1 and 2 page 27) and by pressing the motor-stop lever (A fig.1 and 2).
By releasing the motor-stop lever the transmission stops at once, including the rotation of the PTO, but the motor is still operational; to turn it off, enable the motor-stop lever (B fig.1 and 2).
In machines equipped with EasyDrive ® transmission the relevant red ED lever must be enabled (Q fig.2/d) to begin the change transmission.
Reverse is obtained by enabling lever L (fig.1 and 2). In machines equipped with EasyDrive ® transmission this is the same lever as the drive control (Q fig.2/d).
Warning! To use the machine, personal protective equipment (PPE) must be used as well as safety footwear, earmuffs, glasses, work gloves, etc. Always carry out cleaning or maintenance operations on the machine or equipments in observance of
the safety warnings contained in this handbook.
Prior to starting up the machine, you must be aware of the various safety devices and controls.

8.2 Checks prior to starting the engine

• check that the engine cooling suction grills are clean;
• check that the engine oil is at a certain level;
• check that the transmission lever is in neutral;
• check that the PTO lever is in a disabled position;
• check that the air filter is clean. If not, clean or replace it;
• check that the assembled implement is clear, secured tothe machine and complete with safety guards;
• check that there is sufficient fuel in the tank.

Important! Clean, fresh fuel must be used, which is kept in suitable places. If this is not the case, the carburettor, injection system and motor could be damaged. Remove cap and fill the fuel tank using a funnel with a very fine filter.
Do not use old, poorly stored or contaminated fuel; the manufacturer and reseller shall not be held liable for the quality and storage of fuel by the owner of the machine.

TO START THE MACHINE AND BEGIN THE WORK

See fig.1, 2, 3, 4 at pages 27 and 28.
Before starting the engine, ensure that it is in neutral and that the power supply is not connected.

1. Turn the engine stop lever B to position I (ON).

2. Prepare the engine to start, reading the use and maintenance manual for necessary operations.

3. Slowly pull the starting handle until the hooking system is engaged, enable the decompressor, if present on diesel motors, then give a strong pull placing the foot (fig.21). The rope handle must always be grasped with ONE HAND ONLY, to prevent the engine “kicking back”.

4. Once the engine has been started, leave it running for a few minutes, allowing enough time for the oil to reach the moving parts.

5. Hold the handlebar, pull in the clutch lever C, lower the red STOP lever A and select the required gear. To change gears or enable the reverse, the clutch must always be used. The EasyDrive ® hydraulic device lets you go from forward to reverse gear and vice versa without using the clutch.

6. After having released the parking brake N, slowly release the clutch lever and the machine will begin to move.
   For Powersale ® machines:
   When the machine is powered, if lever Q (fig.2/d) is in the central position, the machine doesn’t move even if the gear is engaged. By rotating the lever in a clockwise direction, the machine moves backwards; pressing the lever completely down, it locks in the back-ward position; just press in 1 to unlock and bring it back into the central position.
   By rotating the lever in an anticlockwise direction, the machine moves forward; by pressing the lever completely down, it locks in the forward position. By pressing in 2, the lever unlocks, goes back into the central position and the machine stops. WARNINGS:
   – The speed of the movement depends on the rate of the motor and the ratio engaged as on the machines with mechanical change.
   – When the machine is powered, if lever Q (fig.2/d) is in the central position (not pressed), you can change gear by moving the change lever without having to use the centre friction of the motor.
   – With the handlebar in retroverted position (motor close to  the operator), rotating lever Q in a clockwise direction ill   ove the machine  forwards, whereas rotating it anticlockwise will move the machine backwards.

7. To put the equipment into use, pull in the clutch lever C and select PTO, operating the lever E on the column; then accelerate the engine, slowly release the clutch and begin work.

8. When work is finished, to stop the  motor   decelerate, disengage the power supply and select neutral gear; then engage the  parking   brake and turn the engine stop lever   to position 0 (OFF).

In case of emergency, release the red STOP lever “A”. The machine and equipment will stop immediately, while the engine will continue to run.

LUBRICATION AND MAINTENANCE

A proper maintenance and lubrication will help keep the machine in a perfect working condition. The machine is delivered full of lubricants, however check oil  levels before starting work.heck that all screws and nuts are well tightened; particularly nuts D (fig.13 and 16) that fix the attachments to the machine, the nuts that fix wheels and ones fixing the engine. Lubricate the sliding bushes of the steering column stop rod-justment besides oil and filter replacement, as shown on page 41 for the transmission box. Fig.26 shows the hydraulic operating diagram of the machine. If a new adjustment is required, please refer to page 61.

10.2 Engine
For the maintenance intervals follow the instructions given in the operating manual of engine. You should check the oil level every 4 hours of work and replace it yearly or every 100 hours of work. Always use good quality oil as indicated on the motor instruction book.
Oil bath air filter: if you work in dusty conditions intensifying cleaning, wash the filtering hank and add oil every 8 hours.

Use the same oil as for engine. For engines that have an air filter with paper filter component, these should be cleaned with air or replaced if very clogged, punctured or if the sealing surface has become damaged. Do not use the engine if the filter is in poor condition or missing.
10.3 Gearbox
FIRST 30 HOURS – After the first 30 hours of work, replace the oil filter A. Check the level in the transmission box using the cap with rod (C fig.23 – 24) and checking that, with the machine horizontal, the oil reaches in between the two notches 1 and 2 (fig.24). If necessary add hydro-mechanical gear oil BCS Powerlube W7 (API GL-5). See Service Bulletin 2-22 for more information!

TO REPLACE THE OIL FILTER “A” (fig.23)

1. Remove the filter, unscrewing it with the correct span-ner.
2. Smear a film of oil on the rubber gasket of the new filter.
3. Mount the new filter, screwing and tightening it only by hand.

EVERY WEEK – With the machine on a level surface, check that the oil reaches between the two notches on the dipstick cap C (fig.23 – 24).

EVERY 100 HOURS OF WORK, OR AT LEAST ONCE A YEAR
Change the oil (2,3 litres capacity for 710 – 728 – 730 Easy Drive – 738 – 739; 2,6 litres capacity for 740 – 749 – 750), the oil filter A (fig.23) and clean the magnetic cap B (fig.25) after having removed it from its place.

11.3 Pneumatic wheels
They are particularly suitable for agricultural uses since the claw tread always provides good adherence of the machine to the ground, either on hard or soft grounds.
The wheels 4.00-8 (fig.39) do not have the rim with adjustable track. However it is possible to change the track in- verting the assembly of the same wheels. The wheels 4.010,  5.0-10 and 6.5/80-12 have the rim with adjustable track, which offers two assembling possibilities with different tracks (fig.40).
When working with ploughs and ridgers it is advisable to mount wheels with a larger diameter (for ex. 6.5/80-12). Their larger diameter and their claw tread increase the adherence to the ground and their traction.
These wheels can be fitted also with the other implements: lawn mower, bars, etc., by fitting on the gearbox P.T.O. the implement extension or quick hitch, in order to avoid interferences between the wheels and the implements.
11.4 Steel cage wheels
These wheels are specially designed to be used with the two-wheel tractor mounting the rotary hoe on hard ground.
The crosspieces on the wheels perimeter penetrate the ground, and assure good griping of the machine to the earth, and prevent slippage. Cage wheels are profitable to use only in these conditions.
Otherwise it is better to use pneumatic wheels which, if there is no severe problem of adherence, give the machine a steadier traction and form a flexible buffer between it and the ground. These wheels are available with diameter 43 cm and 49 cm (see fig.43).

11.5 Wheels “Super-Bite” (antidrift)
Those wheels are particularly recommended to mow on sloping ground. Coupled to pneumatic wheels they increase both  the tractionand lateral stability of the machine (fig.44). They are available only to couple to wheels 4.00-8 and 5.0-10.
11.6 Wheels twinning
The wheels 4.00-8 and 4.0-10 can be twinned installing two 6 cm spacers D (fig.45) between the two wheels (see Wheel Spacers).

11.7 Wheel spacers (fig.46)
These spacers are used to widen the track and thus in- crease the stability of the machine on sloping ground. They are mounted between the wheels and the hubs and widen the track by 6 cm on each side.
11.8 Ballasts for equipment
To balance the machine with various equipment that can be assembled, various types of ballast are available for use on the equipment. They are manufactured in a specific way for every piece of equipment. The following ballasts are available:

• ballast for “professional” snow blade (kg 9);
• ballast for turbine snow plough cm 60 (kg 4.5);
• ballast for turbine snow plough cm 70 (kg 5.5);
• ballast for Bladerunner (kg 14);
• ballast for standard oil immersion transmission and Duplex (kg 15).

11.9 Ballasts for wheels
These ballasts are used to make the machine heavier and to have therefore a higher tractive force. They can be used for ploughing or ridging. They must be fixed to the wheel hubs with two of the four nuts fastening the wheels (fig.48).
See table 1 page 19.
11.10 Machine weights for 750
Using three screws, it is possible to apply 2 weights (fig.49) to the machine (one per side). These can be fitted directly onto the supports positioned on the gearbox (fig.50).
These weights are used to optimally balance the weight of the handlebar in the event that the machine is fitted with a petrol engine and used with particularly heavy tools, such as the 85/100 cm milling cutter, or to weight down further (in addition to the wheel weights) during ploughing.

11.11 Rotary hoe wheel
This wheel is very useful when moving the machine on long distance because it holds the hoe up off the ground and makes travelling easier (fig.51).
11.12 Cutter bar front protections
It is recommended to apply the front protection each time a transfer is performed or whenever the bar remains exposed or in the deposit (fig.54).

11.13 Cutter bar side protections
Their purpose to avoid that the blade, when it comes out from the bar seat during its running, damages itself or the near plants knocking against obstacles or stones.
They must be fitted at the ends of the cutter bar; for the Europe cutter bar, fit protection A (fig.55), for the cutter bars with low cut or middle cut finger fit protection B (fig.56).
They can also be used as accident prevent tools.

11.14 Quick hitch for implements
It allows to change rapidly the implements on the machine. It consists of 2 parts: a shank A and a sleeve B (fig.58 – 58/b).
To assemble the equipment on the machine just insert shank A in sleeve B and hook them by lowering pin G. On two-wheels tractor 750 it is assembled as standard and hooks by turning red knob G (fig.58/b).
For every piece of equipment, shank A is needed, or sleeve B if it is a 750. Keep sleeve B and shank A always lubricated with grease to make assembly and disassembly easier (fig. 58).

11.15 Standard power take off D=35 (1″ 3/8)
This PTO fitted on the ma-chine PTO, takes out a splined shaft which as Ø = 35 mm and unified size 1″ 3/8, like the tractors PTO’s, according to DIN standards 9611. By this shaft you can drive pulleys, universal joints and many other implements (fig.59).
11.16 Equipment extension mm 80
Equipment extension mm 80 (fig.60) is a useful accessory when the weight needs to be balanced between the machine and the equipment with or without the combination of ballasts.The extension should be assembled especially when moving bars are used on hills or inclines, where the bar tends to lift up easily from the ground. They are assembled according to the weight of the motor. It is recommended that 2 combined extensions are assembled.
11.17 Adaptors for PTO
The power take-off adaptors are only 6cm long. They are particularly useful accessories to turn the power take-off of old machines (with splined connection 20×17, Z10) to assemble new equipment with current 3-toothed power take-off (fig.61) or to use old equipment (with shaft 20×17, Z10) on machines with new 3-toothed power take-off (fig.62).

TROUBLE SHOOTING

Do not perform any maintenance with engine on. Below are listed a few small difficulties which may occur and which can be solved by the user.
12.1 Gasoline engine does not start. Make the following checks in the order given:

• the ON-OFF lever is in the ON position;
• the fuel tank is at least half full;
• the fuel tap is open;
• a cold motor must be chocked;
• fuel reaches the carburettor;
• the breather hole in the fuel tank cap is not clogged;
• the carburettor filter is clean;
• carburettor jets are clean. Screw them out to inspect them and, if dirty, clean them with a blast of air;
• the sparking plug sparks. Take out the plug, reconnect it to its wire, touch the plug metal part to the metal part of the machine, and turn the pulley as to start the motor. If a spark is not seen between the plug electrodes, see if the plug wire connections  are tight. If currents still does not reach the electrodes, change the plug. If the motor still does not start with a new sparking plug, the trouble is to be found in the electrical system, coil or other parts.

It is advisable to turn to the nearest Service Point or a specialized shop.
12.2 Diesel motor does not start. Make the following checks in the order given:

• that the ON-OFF lever is in the ON position
• the breather hole in the fuel tank is not clogged;
• the fuel tank is at least half full;
• that the decompressor, if present, is operated. If the motor still does not start, purge the fuel lines of air according to the instructions given by the motor manual. If the motor still does not start, go to the nearest service centre or a specialized shop.

12.3 The machine does not move:

• check that the gear selector has been moved into gear; if it still does not move, take the machine to a Service Centre. 12.4 Machine with rotary hoe. The machine jumps forward on hard ground:

• adjust the central knife moving it as shown the related ma- nual.
  12.5 Machine with the cutter bar. The blade coupling breaks frequently:

• restore the correct clearance between the blade coupling
  and hinge (see bar manual);

• make sure blade-holders are not too tight;  see if there are stones on the ground; if so, lower the cut-ting height adjustment slides to prevent small stones from wedging between the teeth and the blade.

12.6 Cut grass falls in front instead of being ejected at the sides (sickle cutter bar):

• adjust conveyors position or remove shoes. When operating in this way, the cut grass will have to be separated from uncut one by hand to prevent clogging. The “Europa” bar is very useful in these conditions to avoid this kind of problem. See related manual.

STORAGE

If the machine is not be used for a long period of time it is advisable to take the following precautions:

• empty the carburettor;

• empty the motor of oil;

• lubricate the cylinder introducing few drops of the same kind of oil used for the motor through the plug hole and turning the motor over several times without starting it. If it is a Diesel motor remove the injector  y unscrewing the
  two bolts which fasten it to the head and pour a little oil into the hole;

• clean the motor and the machine thoroughly;

• protect the teeth of the bar with the front protection and control that the blade doesn’t escape from the side of the bar;

• when restarting the operations check that all security devices are working.

HOW TO ADJUST THE PowerSafe® CLUTCH

The PowerSafe® clutch is normally adjusted during assembly and therefore requires no further adjustment, except in the event of repairs. However, should a new adjustment or check be required, follow these steps:

1. given that the cables’ worst control condition is with the front implements, the best way to proceed when dealing with motorized tillers is to turn the handle above the engine to the “front gears” position;

2. check that the largest eyelet terminal A (fig.70 – clutch lever terminal B shown in fig.69) is at least 1 mm or 2 mm longer than the eyelet’s coupling pin.
   Adjust the adjusting screw C (fig.71) to obtain the desired length, then tighten the adjusting screw.

3. hook the large eyelet A to the hinge (fig.72) and fit the snap ring retainer D.

4. check that the smallest eyelet terminal E (fig.73 – red stop lever F shown in fig.69) is at least 1 mm or 2 mm longer than the eyelet’s coupling pin. Adjust the adjusting screw G (fig.71) to obtain the desired size, then tighten the adjusting screw;

5. hook the small eyelet E to the hinge (fig.74) and fit the snap ring retainer H.

At this point the adjustment has been carried out correctly; when dealing with motorized tillers, the cable will obtain slightly higher (but still good) clearance by turning the handle.
CAUTION: Do not attempt to remove, tighten or loosen the L screws without knowledge of the PowerSafe® device. In the event that intervention is required, please contact an Authorized Service Centre.

HOW TO ADJUST THE REVERSE CONTROL LEVER

Should a meshing noise occur when the reverse lever L (fig.1, page 27 – fig.75 and 76, page 64) is in the neutral position (position determined by the central tooth Z on the handlebar switch), proceed to adjust the cable through the adjusting screw V (fig.76). The adjustment must be such  that, with the lever resting against the central tooth Z, no meshing noise can be heard.
