Lubrication system

Checking the oil level 

I

 Caution! : 

Carry out these operations with the engine 

stopped. Hot oil and hot surfaces can burn. 
If oil of a different brand or viscosity to the previous is 

used, drain the old oil. Never mix two different types of 

oil. Observe the recommended draining intervals.
The oil level should be within the range indicated on the 

oil gauge. To check the oil level:

• Start  the  engine  and  let  it  run  at  idle  for  several

minutes.

• Stop the engine and remove the starter key.
• Remove and wipe down the gauge rod.
• Re-insert it and then remove it.
• Check  whether  the  oil  level  is  between  the  two

notches. If the level is too low, add more oil until

reaching the specified level.

Top up oil slowly via the filler port located on the top of 

the engine. Add the oil slowly and wait several minutes 

before checking the level again. This allows the oil to 

run into the engine crankcase. 

I

  Caution!  : 

Do  not  fill  the  crankcase  above  the 

maximum level indicated on the gauge.

Draining the engine oil

I

  Warning!  :

  Carry  out  these  operations  with  the 

engine stopped. Hot oil and hot surfaces can burn. 

• Start the engine and let it warm up for approximately

5  minutes  so  that  oil  suction  is  easier.  Stop  the

engine.

• Use a pail to collect the extracted oil and pump until

the  oil  has  been  completely  extracted.  Refill  with

the new oil (the amount of oil to add is indicated in

the technical specifications section).

• Check  the  level  with  the  gauge,  ensuring  you  do

not go above the maximum level.

• Start  the  engine  and  check  that  the  oil  pressure

indicator is extinguished and that there are no leaks

in the lubrication circuit. Let the engine warm up for

several minutes and then check the oil level again.

Fill again if necessary.

Replacing the oil filter cartridge 

 Caution! : 

Carry out these operations with the en-

gine stopped. Hot oil and hot surfaces can burn. 

• Remove the oil filter cartridge with a filter key.
• Clean the filter support in order to prevent impuri-

ties from entering the engine.

• Apply a fine layer of oil over the rubber seal of the

new cartridge.

• To install the new cartridge, tighten it by hand until it

makes contact with the filter head and then tighten

by a half-turn. Over-tightening may lead to the de-

formation of the seal.

• After replacing the filter, check that the engine oil is

not leaking through the seal and check the oil level

using the gauge. Add oil if necessary.
