Air Filter

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal
damage to it. The air filter requires regular maintenance.

Always check the air filter before starting the engine. See

Air Filter

Fuel

Petrol/fuel/gasoline is extremely flammable

– keep clear of naked flames or other ignition

sources. • The engine must be OFF and cool before refuelling. • Always pre-mix the fuel

before placing it in the fuel tank. •

The fuel to 2-stroke engine oil mixture ratio is 25:1

Adequately fill the fuel tank with the correct fuel type.

•

Use non-ethanol unleaded petrol mixed at a

25:1

ratio with 2-stroke engine oil (higher RON values and

good quality 2-stroke oil will provide best engine performance). Do not use old or contaminated fuel/oil.
Fuel/oil mix ratio examples are shown below.

To fill or top up fuel:

1. Place the machine in a horizontal position on a flat and level surface with the fuel filler cap facing up.

2. Clean the machine around the fuel filler so that no dirt or other material enters the engine when the cap

is removed.

3. Remove (rotate left) the fuel filler cap.

4. Using a funnel, carefully fill the tank with fuel. Do not fill above the top of the strainer (if equipped) or

otherwise overfill the tank.

5. When finished, reinstall (rotate right) the fuel filler cap until firm. Wipe away any residual fuel from the

machine. If fuel has been spilt, move the machine away from the spillage before starting the engine.

Saw Chain Lubricant

The saw chain and drive system requires adequate lubricant of the correct type to operate safely and
efficiently. The machine is shipped without chain lubricant. Check the chain lubricant level and ensure that it
is at the recommended level. See

Checking and Adding Chain Lubricant

Spark Plug

The spark plug may come disconnected from the spark plug lead. If this is the case, place the electrical lead
over the spark plug terminal and push it down so that it connects firmly with the terminal. See

Spark Plug

Removal/Installation

Saw Chain Tension

Ensure that the saw chain is correctly tensioned and the chain drive cover nuts are properly
tightened before use and during cutting. • The saw chain will "stretch" with use, so it is

important to check chain tension before and during use • The saw chain cutters are very sharp – wear
suitable protective gloves when handling the saw chain. •

Do NOT check chain tension with the engine

running

. •

Do NOT adjust chain tension with the engine running

Correct saw chain tension is extremely important in terms of both machine efficiency and operator safety.
Check chain tension before each use. Check chain tension frequently during use

– whenever the machine is

put down (engine MUST be stopped first).
