produce general numbness. Continual or regular users should therefore monitor closely the condition of their hands or fingers. If any of the symptoms appear, seek immediate medical advice. 3 Never carry the chainsaw with the engine running. Whenever carrying a chainsaw, even for short distances, the chain should be covered by the chain guard (scabbard) and the bar should point backwards. When transporting the chainsaw in a vehicle, secure the saw to prevent fuel spillage. 4 To avoid kick-back, do not attempt to cut with the nose of the bar. Ensure the engine is running at full throttle before commencing to cut. To avoid kick-back, do not let the nose of the bar come into contact with logs, branches, the ground or any other obstruction. Do not allow any part of the chain to come into contact with rock, nails or wire fence Ensure the chain is kept sharp and correctly tensioned. Keep the spike or the saw body against the wood when cutting. Use only genuine accessories and spare parts. We recommend you have your unit periodically checked and serviced by an authorised dealer. Do not use chainsaw above shoulder height. 5 Do not operate the chainsaw near a naked flame or spilled fuel. Only operate the chainsaw outside and in well ventilated areas. After re-fuelling, always wipe off any spilled fuel. Move the chainsaw away from the fuelling point before starting the engine. 6 Keep by-standers and animals out of the work area; at a minimum distance of 10 m or twice the timber length. If necessary, use warning signs to keep on-lookers at a distance. Carefully survey the working site to note any hazards, eg. roads, paths, electricity cables, dangerous trees etc. Do not use the chainsaw if the device for stopping the chain (safety chainbrake) does not work correctly. Never place hands on the chain whilst the engine is running. Ensure someone is within hearing distance in case of an accident. If this is not possible, it is recommended that users operating chainsaws in remote areas carry an adequate first-aid kit with them and ensure someone knows their location. Never leave the engine running while the tool is unattended. ONLY USE ORIGINAL SPARE PARTS AND ACCESSORIES. Remove the clutch guard (A) and the outer bar plate (F). Check that the oil hole (E) is free from impurities. Fit the chain over the sprocket (H). Ensure correct direction of cutter tooth. Put the bar in position over studs (C) slide it towards the sprocket. Fit the chain into the bar groove and slide the bar forwards. Make sure that the tang chain tensioning screw (D) fits into the hole in the bar (E). Replace the outer bar plate and the clutch guard. Screw the two bar retention nuts finger tight (G). Tension the chain by turning the adjusting screw (I) clockwise while raising the tip of the bar. The tension is sufficient if the chain is snug on the bar but still moves freely around the bar when pulled by hand. Tighten the two bar retention nuts securely. Always use the combination tool to install and tension the chain.

RUNNING IN A NEW CHAIN The chain must always be cold when carrying out adjustment. 1 Let the chain run slowly for a few minutes. Check that the oil pump is delivering oil onto the chain. 2 Stop the engine and adjust the chain tension. 3 Check the tension of a new chain more frequently during initial usage and adjust as necessary. 4 Repeat adjusting until the chain does not stretch any more. Never touch the chain while the engine is running.

FUEL MIX

D

Use only fuel recommended by this manual. This product is fitted with a 2-stroke engine and therefore requires a 2-stroke petrol and oil mix. Use leaded (4 Star) or unleaded petrol with a minimum octane rating of 90. Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol. The use of sub-standard petrol or oil may reduce performance or reduce the life of certain components. LEADED PETROL If using leaded petrol, the correct fuel mix is achieved by either using 5% (20:1) of a well known brand of 2-stroke engine oil, or else 2.5% (40:1) of special McCulloch engine oil. UNLEADED PETROL If using unleaded petrol, you must use a totally synthetic 2stroke engine oil or McCulloch branded 2-stroke engine oil. In either case use 2.5% (40:1) of oil. IMPORTANT Always shake this fuel mix vigorously each time you use it. We recommend to carry out this operation each time you use the fuel. Fuel mix properties deteriorate with time, we therefore recommend that you only make the quantity of fuel mix you will need for each usage. Do not use fuel mix more than a week old as this could damage the engine.
