that are required during use.

HANDLE

1. Fold up the lower part of the handle.

The symbols mean:

2. Secure the upper part of the handle with wash-

ers and locking wheels. There is a lug on the

right hand side for the starter handle (fig. 1).

Important: Read the instruction handbook

before using the

3. Then tighten the locking wheels onto the lower

NOTE! The lawnmower can be operated without

the grass collector. The grass is then left in a line

behind the machine.

USING THE MOWER

COMBI

Your new lawnmower combines two different func-

tions in the same machine:

1. “MULCHING“

Start/Stop loop

Throttle control

Clutch loop

The machine comes equipped with a plug (P),

installed in the ejector opening (fig. 6). The machine

ENGLISH

can be used for ‘Mulching’ i.e. the blade finely cuts

up the grass during mowing. The grass then falls

into the lawn where it is allowed to rot.

This provides the lawn with nourishment.

To remove the plug, press in the catch (R - fig. 6).

On reinstalling the plug ensure that both pins are

pressed firmly into the holes so that the plug snaps

in place.

REAR WHEEL DRIVE (*)

Engage the drive by pressing the clutch loop J

towards the handle. Disengage the drive by releas-

ing the clutch loop J (fig. 7).

CUTTING HEIGHT

2. COLLECTION

Do not set the cutting height so low that

the blade(s) come into contact with

uneven ground.

Assemble the grass collector provided (fig. 5).

Open the flap, remove the plug and instead hook

the collector onto the rear of the machine.

When mowing, the grass is collected in the collec-

tor.

Empty the grass onto the compost heap or spread

it over borders as fertiliser. The machine is also

ideal for collecting up leaves in the autumn.

The mower has single-lever control for adjusting

the cutting height. Pull the lever out, and set the

cutting height to one of the nine positions best

suited to your lawn (fig. 8).

3. REAR EJECTION

MAINTENANCE

Use the mower without the plug or the grass col-

lector (flap closed). The grass is released behind

the machine without being cut up.

IMPORTANT – Regular, careful maintenance is

essential for keeping the safety level and origi-

nal performance of the machine unchanged in

time.

STARTING THE ENGINE

Wear strong working gloves during any cleaning,

maintenance or adjustment operation on the

machine.

1. Place the lawnmower on flat, firm ground. Do

not start in long grass.

Should it be necessary to access the lower part,

only tilt the machine from the side shown in the

engine handbook; following the relative instruc-

tions.

2. Make sure the spark plug cable is connected to

the spark plug.

3. Press in the Start/Stop loop G towards the han-

dle. NOTE! The Start/Stop loop G must be kept

pressed in to prevent the engine stopping (fig.

7).

CLEANING

4. Grasp the starter handle and start the engine by

pulling briskly on the starter cord.

Carefully clean the machines with water after each

cut; remove the grass debris and mud accumulat-

ed inside the chassis to avoid their drying and thus

making the next start-up difficult.

5. For the best mowing results, the engine should

always be driven at full throttle.

The paintwork on the inside of the chassis may

peel off in time due to the abrasive action of the cut

grass; in this case, intervene promptly by touching

up the paintwork using a rustproof paint to prevent

the formation of rust that would lead to corrosion of

the metal.

STOPPING THE ENGINE

The engine may be very warm immedi-

ately after it is shut off. Do not touch the

silencer, cylinder or cooling flanges. This

can cause burn injuries.

Remove the transmission casing by removing the

screws S (fig. 9) and clean around the transmission

and drive belts with a brush or compressed air

once or twice a year.

Release the Start/Stop loopG (fig. 7) to stop the

engine.

Once every season, the drive wheels should be

cleaned internally. Remove both wheels.

If the start/stop loop ceases to work,

stop the engine by removing the spark

plug cable from the spark plug.

Immediately take the lawn mower to an

authorised workshop for repair.

Clean the gear wheel and the wheel gear rim of

grass and dirt using a brush or compressed air (fig.

10).

LUBRICATING DRIVE SHAFT

STORAGE

Once per season, the wedge on the drive shaft

should be greased. Remove the wheel (wheel cap,

screw and washer).

The same petrol must not remain in the tank for

more than one month.

Then remove the circlip and washer so that the

gear wheel can be removed from the shaft.

Lubricate the wedge with universal grease.

Thoroughly clean the mower and store it indoors in

a dry place.

Reinstall the wedge (the wedge is installed differ-

ently on the right and left side, fig. 11 - 12). Install

the gear wheel so that the «L» faces out on the left

side and the «R» faces out on the right side

(machine viewed from the rear).

SERVICING

Genuine spare parts are supplied by service work-

shops and by many dealers.

We recommend that you take the machine to an

authorised service station for annual servicing,

maintenance and inspection of safety equipment.

ADJUSTING CLUTCH CABLE

If the drive does not engage when the clutch loop

is pressed against the handle, or if the lawnmower

feels cumbersome or slow, this may be because

the clutch in the transmission is slipping.

For service and spare parts, please contact the

dealer where the machine was purchased.

To rectify this situation, adjust the clutch cable as

follows (with the engine off):

1. When the clutch loop is released, it should be

possible to push the mower backwards without

any resistance. If this is not the case, screw in

the nipple T until the mower can be pushed (fig.

13).

2. When the clutch loop is pressed in approx. 2 cm

(position 1), there should be some resistance

when pushing the lawnmower. With the clutch

loop fully pressed in (position 2) it should not be

possible to push the mower. Unscrew the nipple

T until this position is achieved.

CHANGING BLADES

To replace the blade, undo the screw (fig. 14).

Fit the new blade so that the stamped logo is

turned up facing the blade holder (not facing the

grass).

Reinstall as illustrated. Tighten the screw properly.

Tightening torque 40 Nm.

When replacing the blade, the blade screw should

also be replaced.

SHARPENING THE BLADES

Sharpening of the blades must be done by wet

method grinding, using a whetstone or a grind-

stone.

For safety reasons, the blades should not be

sharpened on an emery wheel. A very high temper-

ature could cause the blades to become brittle.
