Owner's Manual

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-fueling, always wipe off any spilled fuel. Move the chainsaw away from the fueling 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 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 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 whilst 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. WARNING Mount the bumber spike as shown in illustration. 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.

D FUEL MIX
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 or unleaded petrol with a minimum octane rating of 90. When using leaded petrol, use 2.5% (40:1) of McCulloch oil, otherwise use 5% (20:1) of a high quality 2-stroke engine oil (from a recognised brand). When using unleaded petrol, use 2.5% (40:1) of McCulloch oil or use 2.5% (40:1) of a high quality synthetic 2-stroke engine oil.. Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol.
