BACKPACK BLOWER OPERATOR’S MANUAL
Important!
It is essential that you read the instructions in this manual before assembling, operating and maintaining this machine.
early in the morning or late at night when people might be disturbed.
WARNING When using the product, the safety rules must be followed. For your own safety and that of bystanders, please read these instructions before operating the product. Please keep the instruction safe for later use.
■■ Use rakes and brooms to loosen debris before blowing/vacuuming. ■■ Never operate the product in an explosive atmosphere. ■■ Do not use this machine when you are tired, ill, or under the influence of alcohol, drugs, or medication.
WARNING
■■ Do not operate in poor lighting. The operator requires a clear view of the work area to identify potential hazards.
Never allow children or people with reduced physical, sensory or mental capabilities to operate, clean or maintain the product. Local regulations may restrict the age of the operator.
■■ Use of hearing protection reduces the ability to hear warnings (shouts or alarms). The operator must pay extra attention to what is going on in the working area. ■■ Only use enough throttle (power) to complete the task, this will reduce the potential for injury caused by noise and vibration.
■■ Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the product and the cutting activity. Never assume that children will remain where you last saw them.
■■ Operating similar tools nearby increases both the risk of hearing injury and the potential for other persons to enter your working area.
■■ Keep children out of the work area and under the watchful care of a responsible adult other than the operator, be alert and turn the product off if a child enters the area.
■■ Keep firm footing and balance. Do not overreach. Overreaching can result in loss of balance or exposure to hot surfaces.
GENERAL SAFETY RULES
■■ Keep all parts of your body away from any moving part. Rotating impeller blades can cause severe injury. Stop the engine and ensure impeller blades have stopped rotating before opening the vacuum door, installing/ changing tubes, opening or removing debris bag.
■■ Some regions have regulations that restrict the use of the product to some operations. Check with your local authority for advice. Read all instructions. ■■ Do not allow children or untrained individuals to use this unit.
■■ Do not touch the area around the silencer or engine of the unit, these parts get very hot during operation.
■■ Ensure before each use that all controls and safety devices function correctly. Do not use the tool if the “off” switch does not stop the engine.
■■ Inspect the machine before each use. Check for loose fasteners, fuel leaks, etc. Make sure all guards, and handles are properly and securely attached. Replace any damaged parts before use.
■■ Never start or run the engine in a closed or poorly ventilated area; breathing exhaust fumes can kill.
■■ Never run the unit without the proper equipment attached. When used as a blower, always install the blower tubes and close the door. When used as a vacuum, always install the vacuum tubes and vacuum bag.
■■ Clear the work area before each use. Remove all objects such as rocks, broken glass, nails, wire, or string which can be blown a considerable distance by high velocity air. ■■ Wear full eye and hearing protection while operating the product. This machine is extremely noisy and permanent hearing may result if precautions to limit our exposure, reduce noise and wear hearing protection are not strictly adhered to.
■■ Do not modify the machine in any way or use parts and accessories which are not recommended by the manufacturer.
WARNING
■■ Wear heavy long trousers, boots, and gloves. Do not wear loose fitting clothing, short trousers, jewellery of any kind, or use with bare feet.
If the machine is dropped, suffers heavy impact or begins to vibrate abnormally, immediately stop the machine and inspect for damage or identify the cause of the vibration. Any damage should be properly repaired or replaced by an authorised service centre.
■■ Secure long hair so it is above shoulder level to prevent entanglement in moving parts. ■■ Beware of thrown objects; keep all bystanders, children, and pets at least 15 m away from work area.
■■ Stop the engine and allow it to cool before refuelling, storing or transporting the machine.
■■ Operate the machine only at reasonable hours – not 2
■■ For refuelling and fuel mixing, chose an area away from sources of ignition (sparks, flames etc.), Flammable materials and which is well ventilated.
WARNING Your back pack blower is fitted with a shoulder harness. Carefully adjust the harness to comfortably help to support the weight of the machine and secure it to your back.
■■ Do not smoke when mixing fuel or filling fuel tank. ■■ Mix and store fuel in a container approved for fuel. Keep an appropriate type of fire extinguisher nearby for dealing with fuel fires.
WARNING
■■ Remember to securely refit the fuel tank filler cap before starting the engine.
Identify how to operate the quick release mechanism and practice using it before you start using the machine. Its correct use may prevent serious injury in the case of an emergency. Never wear additional clothing over the harness or otherwise restrict access to the quick release mechanism.
■■ Wipe up any fuel spillage. Move 10 m away from refuelling site before starting engine. ■■ It has been reported that vibrations from hand-held tools may contribute to a condition called Raynaud’s Syndrome in certain individuals. Symptoms may include tingling, numbness and blanching of the fingers, usually apparent upon exposure to cold. Hereditary factors, exposure to cold and dampness, diet, smoking and work practices are all thought to contribute to the development of the these symptoms. There are measures that can be taken by the operator to possibly reduce the effects of vibration: ●● Keep your body warm in cold weather. When operating the unit wear gloves to keep the hands and wrists warm. It is reported that cold weather is a major factor contributing to Raynaud’s Syndrome. ●● After each period of operation, exercise to increase blood circulation. ●● Take frequent work breaks. Limit the amount of exposure per day. If you experience any of the symptoms of this condition, immediately discontinue use and see your doctor about these symptoms.
BLOWER SAFETY WARNINGS ■■ Wear a face filter mask in dusty conditions to reduce the risk of injury associated with the inhalation of dust. ■■ Do not point the blower nozzle in the direction of people or pets. ■■ Never place objects inside the blower tubes. ■■ Do not operate the machine near open windows etc. ■■ Slightly dampen surfaces in dusty conditions. ■■ Use the full blower nozzle extension so the air stream can work close to the ground. ■■ Do not place blower on top of or near loose debris. Debris may be sucked into intake vent resulting in possible damage to the unit. ■■ Check all nuts, bolts and screws at frequent intervals for proper tightness to ensure the product is in safe working condition. Any part that is damaged should be properly repaired or replaced by an authorised service centre.
WARNING Injuries may be caused, or aggravated, by prolonged use of a tool. When using any tool for prolonged periods, ensure you take regular breaks.
■■ If your blower looses power or the engine speed increases, this may indicate a blockage to the air inlet. As this may require the removal of the engine from the back pack we suggest to take the machine to an authorised service centre for inspection.
■■ To reduce the risk of injury associated with contacting rotating parts, always stop the engine, remove the spark plug wire and make sure all moving parts have been come to a stop before ●● cleaning or clearing a blockage ●● leaving the product unattended ●● install or removing attachments ●● checking, maintenance or working on the machine
SERVICE Servicing requires extreme care and knowledge and should be performed only by a qualified service technician. For service we suggest you return the product to your nearest authorised service centre for repair. When servicing, use only identical replacement parts.
