1. Place the Brush Trimmer Shaft (16) assembly on a secure, flat surface with the Cutting Head Assembly (3)
directed upwards
2. Lock the rotating head into place by inserting the Small Hex Key (31) into the opening in the Cutting Head
Assembly (Image D). Using the Spark Plug Combi Tool (35), unscrew and remove the 19mm nut from the
Cutting Head Assembly
3. Remove the locking washer and place the Brush Cutter Blade on to the locating washer (Image E)
4. Reinstall the locking washer, ensuring the teeth align with the grooves on the shaft, and tighten down the

1. Follow Steps '1-2' under 'Brush cutter head assembly'
2. Remove the locking washer and screw the Bump Feed Spool Head (28) directly onto the threaded shaft
Brush trimmer guard installation

Guide bar and chain assembly
WARNING: ALWAYS wear cut-proof gloves when assembling or carrying out any maintenance to the chainsaw.
1. Place the chainsaw head assembly on a secure flat surface along with the Guide Bar (24) and Saw Chain
(25)
2. Remove the Guide Bar Securing Nut using the Spanner (32) provided, then remove the Sprocket Cover (2)
3. Install the Guide Bar on to the chainsaw head, ensuring the Tensioning Lug (45) locates in the Guide Bar's
locating hole (Image H)
4. Install the Saw Chain into the groove on the Guide Bar and around the Sprocket, ensuring the Saw Chain is
the correct orientation
Note: To ensure correct orientation of the Saw Chain, place the chain saw head in the upright position (with the
Chain Oil Reservoir Cap (50) directed upwards). The Saw Chain direction marking should be upright. Install
chain in accordance with (Fig. I).
Note: The Guide Bar Securing Nut may have to be installed loosely whilst installing the Saw Chain, to help
secure the Guide Bar in place.
5. Reinstall the Sprocket Cover and fasten the Guide Bar Securing Nut loosely
6. Tension the Saw Chain by turning the Tensioning Screw (46) with the Multi Screwdriver (34). Clockwise
tensions the chain; anti-clockwise loosens the chain. Tighten until the Saw Chain sits snug to the bottom of
the Guide Bar
7. Tighten the Guide Bar Securing Nut Securely
Note: A new saw chain will expand when first used. Check and readjust the chain tension frequently, as a
loose chain can easily derail, and incorrect chain tension leads to premature wear, damage and encourages
dangerous kickback.

Preparing 2-stroke mix
WARNING: ALWAYS use dedicated fully synthetic 2-stroke oil. DO NOT use regular engine oil for 2-stroke mix.

below
Unleaded Petrol
40:1
Fully Synthetic 2-Stroke Oil
WARNING: DO NOT pour oil directly into the Fuel Tank (36). The 2-stroke mix needs to be prepared and
thoroughly mixed in a separate container before adding to the chainsaw.
2. Pour the required amount of 2-stroke oil followed by unleaded petrol into the Fuel Mixing Bottle. Close and
shake until thoroughly mixed
Note: 2-stroke mix must not be stored long-term. ONLY mix the amount required for immediate consumption.
Refer to the 'Storing Fuel' section for further information.
Filling with fuel
WARNING: Danger of fire and burn injuries. Take extra care when fuelling this machine.
WARNING: NEVER fill with fuel whilst the engine is running. Switch off the engine and wait until it has cooled
before refuelling.
WARNING: ONLY refuel the hedge trimmer outdoors, in well-ventilated areas.
WARNING: ALWAYS open the fuel tank carefully to allow potential pressure build-up inside the tank to release
slowly. Never open the fuel tank while the engine is running.
• Always use extreme care when handling fuel. Fuel is highly flammable
• Never attempt to fuel the hedge trimmer if the fuel system components are damaged or are leaking
• Never attempt to refuel the engine while it is running or still warm; allow it to cool before fuelling
• Never smoke or light fires near the hedge trimmer or fuels
• Always transport and store fuels in an approved container
• Never place flammable material close to the engine exhaust
• Do not use petrol which contains ethanol or methanol as it may damage the fuel lines and other engine
parts
• Mix only enough fuel for immediate needs. If fuel must be stored longer than 30 days, it should first be
treated with a stabiliser or similar product
1. Premix the fuel in a suitable 2-stroke fuel mixing bottle, following the guidelines under 'Preparing 2-stroke
mix'
2. Place the unit on a secure, flat surface and wipe away any debris from around the Fuel Cap (37)
3. Unscrew the Fuel Cap and pour the mixture into the tank with the aid of a funnel
Note: Take care not to spill any of the fuel mixture. If this happens, wipe the spill with a clean rag.
• In order to avoid risk of fire, start up the engine at least three metres away from the area where the Fuel
Tank has been filled
