CAUTION!
If the saw chain is TOO LOOSE or TOO TIGHT the V-drive wheel, chain bar,
chain and crank shaft bearing will suffer premature wear. Above fig. shows the correct
tension A (when cold) and tension B (when warm). Fig. C shows a chain that is too loose.
2 Tighten the chain cover.
Step 3 - Filling with engine fuel and lubrication
This product is powered by a 2-stroke engine and requires pre-mixing of petrol and
2-stroke oil. Use a high quality 2-stroke engine oil according JASO FC classic. Do not use
automotive oil or 2-stroke outboard oil. DO NOT mix quantities larger than usable in a 30-
day period.

FUEL MIXTURE: 1 Litre (1000ml) petrol: 25cc (25ml) 2-stroke engine oil (40:1 ratio)
Using a funnel and keeping the bottle level, pour the fuel in the left hand side (A) up to the
required level, e.g. 2.5 or 5, then fill the right hand side (B) up to the same corresponding
mark with oil. Shake vigorously to mix the two products prior to pouring into the tank (C).
NOTE:
Use 5 for 500ml fuel mixture and 2.5 for 250ml fuel mixture.
FILLING THE LUBRICATION
Whenever you refill the fuel tank with petrol you must also top up the level of chain oil in the
chain oil reservoir (D). Use special chainsaw oil to lubricate the saw chain.
NOTE:
Most stores will sell acceptable oil under the name ‘chainsaw chain oil’.
FILLING THE FUEL TANK
Clean the surface around the fuel cap to prevent contamination. Loosen the fuel cap slowly.
Remove and rest the cap on a clean surface. Carefully pour fuel into the tank to avoid
spillage. Prior to replacing the fuel cap, clean and inspect the seal located inside the fuel
cap
. Immediately replace the fuel cap and hand tighten. Wipe up any fuel spillage.
NOTE:
It is normal for smoke to be emitted from a new engine after first use.
IMPORTANT!
The fuel mix is added into fuel tank (C), chain lubrication oil is filled into oil
reservoir (D). Seal one cap prior to removing the second cap. If you put the fluid
into the wrong tank, call the customer helpline immediately on 01904 727500.
