Intended use of the 31cc 4 Stroke Brushcutter / Line Trimmer
NOTE: This product is for private domestic DIY use only.
It is not suitable for commercial or trade use.
This Line Trimmer has been designed for trimming lawn edges and grass around shrubs and trees.
The Brushcutter has been designed for cutting and clearing grass, thick weeds, vegetation and shrubs.
WARNING! Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
The word power tool used in the following warnings and throughout this manual refers to BOTH electrical power tools and ALSO petrol driven power tools.
This unit may not be used by people (including children) with reduced physical, sensory or mental capacities, with a lack of experience and without the appropriate knowledge, unless they are supervised by someone who is responsible for their safety or have been instructed by such a person with regard to how the unit is to be operated. Children should be supervised to ensure that they do not play with the device.
Save all warnings and instructions for future reference
1. Work area safety a. Keep work area clean and well lit. Cluttered or dark areas invite accidents. Rags, cloths, cord, string and similar items should never be left around the work area.
b. Do not operate power tools in explosive environments, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks, which may ignite the dust or fumes. c. Keep children and bystanders away while operating a power tool.
Distractions can cause the operator to lose control.
2. Electrical safety
a. Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with grounded power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b. Avoid body contact with grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is increased risk of electric shock if your body is grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately.
Damaged or entangled cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor reduces the risk of electric shock. f. To reduce the risk of electric shock, the manufacturer recommends the
use of a residual current of 30mA or less at all times.
3. Personal safety
a. Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
a. Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection will reduce personal injures.
a. Prevent unintentional starting. Ensure the switch is in the “off” position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
a. Remove any adjusting key or wrench before turning the power tool on.
A wrench or key left attached to a rotating part of the power tool may result in personal injury.
a. Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
a. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
a. If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used.
Use of dust collection can reduce dust-related hazards.

General safety warnings
4. Power tool use and care
a. Do not force the power tools. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
a. Do not use the power tool if the switch does not turn it “on” and
“off”. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
a. Disconnect the plug from the power source and/or the battery
pack from the power tool before making any adjustments,
changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
a. Store idle power tools out of the reach of children and do not
allow persons unfamiliar with the power tool or these instructions
to operate the power tool. Power tools are dangerous in the hands of untrained users.
a. Maintain power tools with care. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
a. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
a. Use the power tool, accessories and tool bits etc. in accordance
with these instructions, taking into account the working
conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

Additional Safety rules for Petrol Brushcutters
WARNING: Extreme care must be taken when using blades to ensure safe operation. Read the safety information for safe operation using the blade.
• Follow all sections of the Additional Safety Rules for Petrol Products.
• Always hold Brushcutter with both hands when operating. Use a firm grip on both handles.
• Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kick-back reaction of the cutting blade.
• Inspect and clear the area of any hidden objects such as glass, stones, concrete, fencing, wire, wood, metal, etc.
• Never use blades near footpaths, fencing, posts, buildings or other immovable objects.
• Never use a blade after hitting a hard object without first inspecting it for damage. Do not use if any damage is detected.
• The unit is used as a scythe, cutting from the right to the left in a broad sweeping action from side to side.
• Always wear goggles, earmuffs and a dusk mask when using the
Brushcutter.
• Only use blades with a cutting diameter of 255mm and a bore size of 25.4 mm.
• Only use the Brushcutter with the correctly supplied and fitted
Brushcutter guard.
• Keep bystanders a minimum of 15 metres from the operation of the
Brushcutter.
• Prior to operation, ensure the assembled Brushcutter is checked for loose components and the operating controls of the Brushcutter.
Do not use the Brushcutter if the controls are not in perfect working order. Ensure all nuts, bolts and clamps are all tight.
• Check the blade is correctly seated and the blade nut is tight.
• DO NOT substitute the blade with any other types of blade other than that is detailed in this manual. DO NOT fit a saw blade to this product.
• This brushcutter is fitted with a centrifugal clutch. At idle, the blade must not be rotating. Make a practice to always check the clutch is correctly operating and at idle the blade does not rotate, and rotation of the blade only occurs as the speed of the motor is increase from manually operating the speed trigger.
Do NOT use the brushcutter if the blade at idle speed is rotating and take it to an authorised service centre.
• Exercise extreme caution when using the 3T brushcutter blade with this unit. Blade thrust is the reaction which may occur when the spinning 3T brushcutter blade contacts anything it cannot cut.
This contact may cause the 3T brushcutter blade to stop for an instant, and suddenly “thrust” the unit away from the object that was hit.
This reaction can be violent enough to cause the operator to lose control of the unit. Blade thrust may occur without warning if the blade snags, stalls or binds. This is more then likely to occur in areas where it is difficult to see the material being cut.

Tips for Operation
Always use the double shoulder strap harness (31) when using the brushcutter to avoid serious personal injury.
Hold the brushcutter with one hand on the trigger handle and the other hand on the J handle (12). Keep a firm grip with both hands while in operation. The brushcutter should be held at a comfortable position with the double shoulder strap attachment point (31) about hip height.
Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kick-back reaction of the 3T brushcutter blade (28).
When using the double shoulder strap harness (31), adjust to position the double shoulder strap attachment point (37) on the brushcutter at approximately hip height.
Exercise extreme caution when using the 3T brushcutter blade (28) with this unit. Blade thrust is the reaction which may occur when the spinning
3T brushcutter blade (28) contacts anything it cannot cut. This contact may cause the 3T brushcutter blade (28) to stop for an instant, and suddenly
“thrust” the unit away from the object that was hit.
This reaction can be violent enough to cause the operator to lose control of the unit. Blade thrust may occur without warning if the blade snags, stalls or binds. This is more then likely to occur in areas where it is difficult to see the material being cut.
For cutting ease and safety, approach the weeds being cut from the right to the left. In the event that an unexpected object or woody stock is encountered, this could cause the blade thrust reaction.

Prior to operating the line trimmer after line has been added, it is suggested to trim the lines so they are even and just short of the cutting blade on the guard. This prevents a possible large section of line being trimmed at high speed. When you start the line trimmer, bump the head of the spool on the ground to enable the cut off knife on the guard to cut the line to the required length for use.
Operation of the Line Trimmer
To start the line trimmer, refer to the instructions on page 30 .
NOTE: This is a 4 stroke brushcutter / line trimmer.
The motor MUST be filled with 60mL of SAE 10W/30 BEFORE starting.
Fresh unleaded fuel must be used in this unit.
Do NOT use ethanol based fuels. Do NOT mix oil with fuel.
Use of the Line trimmer
This petrol line trimmer is only made to cut grass.
• Always use the double shoulder strap harness (31) when using the line trimmer to avoid serious personal injury.
• Perform a few accelerations of the motor without reaching maximum speed and without working to make sure that everything is in good working order.
AU.
• Start the engine only when you are close to the working area.
• Place yourself in a well balanced position, stable on both feet.
Advancing the line manually
NOTE: Always ensure the engine is turned off before undertaking this task.
1. Push the bump knob (34) in while pulling on both lines to manually advance the line. (Fig. AU)
2. Release the bump knob and again pull on both lines to advance the line further. (Fig. AV)

WLBCF310 INSTRUCTION MANUAL www.909.com
Tips for operating the Line Trimmer
IMPORTANT. Petrol line trimmers transmit vibrations to the operator during use. These vibrations can generate increased fatigue. For this reason, we recommend taking regular breaks during work. We also recommend taking a break after a few hours of work to rest the engine. If abnormal noise or vibration occurs during operation, turn the line trimmer off immediately and have the problem corrected.
Keep a firm grip on the trimmer with both hands while in operation.
The trimmer should be held at a comfortable position with the rear handle about hip height.
Always operate the trimmer at full throttle. Cut tall grass from the top down to prevent grass from wrapping around the spool which may cause the trimmer to overheat.
NOTE: If grass becomes wrapped around the spool, stop the engine, disconnect the spark plug wire, and remove the grass.
Tips for cutting
WARNING.
Beware of bystanders at all times
• Cut the grass like you are in a corridor about 1.5m wide.
Move step by step, moving the machine from left to right and vice-versa.
Make sure at each step that you are still well balanced on your feet
• Keep the line trimmer tilted towards the area being cut
• Let the tip of the line do the cutting. Never force the spool into uncut grass.
• Running the line into fences, stone and brick walls, curbs, and wood causes extra line wear, even breakage.
• Do NOT run the bump knob (34) on the ground during the cutting process. The bump knob (34) should only touch the ground when the bump knob (34) is tapped on the ground to extend the cutting line.
28
WLBCF310 INSTRUCTION MANUAL www.909.com
WLBCF310 INSTRUCTION MANUAL www.909.com
WLBCF310 INSTRUCTION MANUAL www.909.com
Feeding the line
The line trimmer has a bump feed mechanism which releases the line without having to stop the engine.
1. To release additional line increase the speed of the motor to no less than half speed, then, lightly tap the bump knob (34) on the ground while operating the unit at high speed.
NOTE: Always keep the line fully extended for optimum cutting performance. Line release becomes more difficult as the cutting line becomes shorter. Cutting efficiency also decreases as the line becomes shorter.
The line will not extend if the speed of the spool is not operating at least half speed. If the line does not extend, increase the speed to full speed while tapping the bump knob on the ground. If the line still does not extend, stop the motor and check the line inside the spool has not tangled and also ensure there is sufficient line in the spool.
2. Each time the head is bumped it releases approximately 2cm of line.
Release the line until it strikes the cut off knife (32). This may require several taps.
NOTE: The cut off knife (32) on the clip-on line trimmer guard attachment (33) will automatically cut off any excess line. For best results tap the head on hard soil or bare ground. Never bump the spool head on concrete as it may crack the spool housing. Make sure the cut off knife (32) protector has been removed.
It is recommended to replace the protector when the line trimmer is not in use.
IMPORTANT. Do not hit stones (even small ones), piles of earth, and small pieces of wood or anything else that could be hidden or poorly visible in the grass. If you hit a large object by accident, or if you jam the cutting tool due to overloading or having the cutter jammed with grass, you must stop the engine.
NOTE: All protective devices of the machine as well as protective equipment must be maintained in good operation condition during the period of use.
NOTE: If the line is too short you may not be able to advance the line by tapping it on the ground. If this is the case, stop the engine and manually advance the line.
