 7.2  PREPARING THE FUEL BLEND

This  machine  is  equipped  with  a  2-stroke  engine 

that requires a blend of petrol and lubricating oil.

 IMPORTANT 

 Using petrol alone damages the 

engine and will void the warranty.

 IMPORTANT 

  Use  only  high  quality  fuels  and 

lubricants to maintain performance and ensure 

the durability of mechanical parts.

 7.2.1  Petrol - characteristics

Use  only  unleaded  petrol  (green  petrol)  with  an 

octane of no less than 90 N.O.

 IMPORTANT 

 Green petrol tends to create 

deposits in the container if stored for more than 2 

months. Always use fresh petrol!

 7.2.2  Oil - characteristics

Use  only  high  quality  synthetic  oil  specific  for 

2-stroke engines.

Your  Dealer  will  have  oils  specially  designed  for 

this  type  of  engine  which  can  guarantee  a  high 

level of protection.

 IMPORTANT 

 To know the percentages of 

oil and petrol to be used, see the "TECHNICAL 

DATA" table.

 7.2.3 

 Preparing and storing the fuel blend

Preparing the fuel blend:

1. 

add approximately half of the amount of petrol 

to a type-approved canister;

2. 

add all the oil;

3. 

add the rest of the petrol;

4. 

close the cap and shake vigorously.

 IMPORTANT 

  The  fuel  blend  is  subject  to 

ageing. Do not prepare excessive quantities of 

fuel blend to prevent the formation of deposits.

 IMPORTANT 

 Keep containers of fuel blend 

and petrol separate and clearly identified to avoid 

swapping them at the time of use.

 IMPORTANT 

 Clean the petrol and fuel blend 

containers  at  regular  intervals  to  remove  any 

deposits.

 7.3  REFUELLING

Before refuelling:

1. 

vigorously  shake  the  canister  containing  the 

fuel blend;

2. 

place  the  machine  on  a  level  surface  in  a 

stable  position  with  the  fuel  tank  cap  facing 

upwards (Fig. 

19.

G).

 NOTE 

  The fuel tank (Fig. 19.G)

has the 

following symbol:

Fuel blend tank.

3. 

Clean the fuel cap and the surrounding area to 

avoid ingress of dirt when refuelling.

4. 

Carefully open the fuel tank slowly to allow the 

pressure to decrease gradually. 

5. 

Refuel using a funnel; do not fill the tank right 

to the top.

 7.4  CLEANING THE MACHINE AND THE 

ENGINE

Always clean the machine after use. 

To reduce the risk of fire:

–

keep the machine and especially the engine 

free  from  residues  of  grass,  leaves  or 

excessive grease;

–

frequently  clean  the  cylinder  fins  with 

compressed  air  and  eliminate  sawdust, 

twigs,  leaves  or  other  debris  from  the 

silencer area.

To  avoid  overheating  and  damage  to  the  engine, 

always keep the cooling air vents clean and free of 

sawdust or debris.

 7.5  NUTS AND BOLTS

• 

Keep all nuts, bolts and screws tight to be sure 

the equipment is in safe working condition.

• 

Check  regularly  that  the  handles  are  fixed 

firmly.

8.  OCCASIONAL MAINTENANCE

 8.1  ANGLE TRANSMISSION 

LUBRICATION

Lubricate with lithium based grease. 

Remove  the  screw  (Fig.  28.A)  and  insert  the 

grease  by  rotating  the  shaft  by  hand  until  the 

grease comes out; then refit the screw (Fig. 28.A).

 8.2  FLEXIBLE SHAFT LUBRICATION

Lubricate with

lithium based grease.
