Carburettor with fixed jets
Your Partner product has been designed and manufactured to
specifications that reduce harmful emissions.
After your unit has been run 8-10 tanks of fuel the engine has
broken in. To ensure that your unit is at peak performance and
producing the least amount of harmful emissions after break in,
have your authorized servicing dealer, who has a revolution
counter at his disposal, to check your carburettor for optimum
operating conditions.
Jets
The carburettor is equipped with fixed jets to ensure the engine
always receives the correct fuel air mixture.
If the engine lacks power or accelerates poorly do the following:
• Inspect or, if necessary, replace the air filter.
• If this does not help, contact an authorised service workshop.

without the cutting arm, belt or cutting head
fitted. Otherwise the clutch can come loose
