Engineering improvements

STIHL’s philosophy is to continually improve all of its products. For this reason we may modify the design, engineering and appearance of our products periodically. Therefore, some changes, modifications and improvements may not be covered in this manual

Safety Precautions and Working Techniques

Special safety precautions must be observed when working with the sweeper drum assembly and bristle brush. Always read and make sure you understand both user manuals (Multi‐Engine and MultiTool) before using your power tool for the first time, and keep them in a safe place for future reference. Non-compliance with the user manuals may cause serious or even fatal injury. Lend or rent your power tool only to persons who are familiar with this model and its operation – do not lend or rent your power tool without the Multi‐Engine and MultiTool user manuals. Use the bristle brush only for sweeping areas and paths, including uneven and jointed surface, and natural stone paving. Use the sweeper drum assembly only for sweeping areas and paths, moving wet materials, such as leaves or dirt to a central point, clearing snow and removing standing water from solid surfaces. Safety Precautions and Working Techniques The machine must not be used for any other purposes – the risk of accident! Only use attachments and accessories that are explicitly approved for this power tool model by STIHL or are technically identical. If you have any questions in this respect, consult your dealer. Use only high-quality parts and accessories. in order to avoid the risk of accidents and damage to the machine. STIHL recommends the use of genuine STIHL tools and accessories. They are specifically designed to match the product and meet your performance requirements. The deflector on this power tool cannot protect the operator from all objects thrown by the attachment (stones, glass, wire, etc.). Ejected objects may also ricochet and strike the operator. Never attempt to modify your power tool in any way since this may increase the risk of personal injury. STIHL excludes all liability for personal injury and damage to property caused while using unauthorized attachments. Do not use a high- pressure washer to clean the power tool. The solid jet of water may damage parts of the unit.

Clothing and Equipment

Wear proper protective clothing and equipment. Clothing must be sturdy but allow complete freedom of movement. Wear close-fitting clothes such as a boiler suit, not a loose jacket. Do not wear clothing that could become trapped in wood, brush, or moving parts of the machine. Do not wear a scarf, necktie, or jewelry. Tie up and secure long hair above your shoulders. Wear sturdy shoes with non-slip soles.

WARNING

To reduce the risk of eye injuries, wear close-fitting safety glasses in accordance with European Standard EN 166. Make sure the safety glasses are a snug fit. Wear “personal” sound protection, e.g. ear defenders. Wear sturdy protective gloves made of a resistant material (e. g. leather).STIHL offers a comprehensive range of personal protective equipment.

Transporting the machine

Always stop the engine. Carry your power tool by the handle, attachment in front of you. Do not touch hot parts of the machine – the risk of burn injury! By vehicle: When transporting in a vehicle, prop‐erly secure your machine to prevent turnover, damage and fuel spillage.

Before starting

Check that your power tool is properly assembled and in good condition – refer to the appropriate chapters in the MultiEngine and MultiTool user manuals.

• Sweeping attachments: correctly fitted, secure, and in perfect condition
• Both sweeping attachments must be mounted.
• Both deflector extensions are fitted for a bristle brush.
• Inspect the deflectors for damage and wear. Do not operate the machine with a damaged deflector
• replace damaged parts.
• Never attempt to modify the controls or safety devices.
• Keep the handles dry and clean – free from oil and dirt – this is important for safe control of the machine.
• Swing the bike handle to the normal operating
• position and tighten it down firmly with the rotary knob. See chapter on “Adjusting the Bike Handle” in the MultiEngine user manual.
• The power tool must only be operated when it is in good operating condition – Risk of accident!
• Check the gearbox for the correct position, and adjust if necessary. This helps reduce the risk of injury from the MultiTool rotating in the wrong direction. See also notes on “Mounting the MultiTool”.

If you use sweeping attachments, position the gearbox so that the axle is above the drive shaft. Use this position for:

• KB-MM bristle brush
• KW-MM sweeper drum assembly

Holding and Guiding the Tool
Make sure you always have a firm and secure footing.

Always hold the unit firmly with both hands on the handles. Right hand on the control handle, left hand on grip on the handlebar.

While Working
In the event of impending danger or in an emergency, switch off the engine immediately by moving the slide control / stop switch/button to 0 or STOP.

To reduce the risk of injury from contact with the tool and ejected objects, do not allow any other persons within a radius of 5 meters of your own position. This distance must also be maintained in relation to objects (vehicles, window panes) –the risk of property damage! The correct engine idle speed is important to ensure that the work tool stops moving when you let go of the throttle trigger. Check and correct the idle speed setting at regular intervals. If the attachment still rotates when the engine is idling, have your dealer check your machine and make proper adjustments or repairs – see MultiEngine user manual. To reduce the risk of injury from thrown objects or contact with the attachment, never operate the unit without a properly mounted deflector designed specifically for the unit and the attachments. Always stand behind the deflector or to one side of the machine during operation – never in front of the attachment. Electrostatic charges may build up when working on synthetic surfaces – the risk of electric shock and accidents! Dust, fumes and smoke produced while working may be hazardous to health! If dust levels are high, wear a suitable respirator. To reduce the risk of a dust explosion, spray very dusty surfaces with water before sweeping. Take special care in slippery conditions – damp, snow, ice, on slopes, or on uneven ground.o reduce the risk of accidents or injury, remove all obstacles and objects from the work area. Check the work site – rocks, metal objects, etc. may be caught up and ejected – the risk of injury. Operate your power tool at a normal walking pace only. Be extremely cautious when pulling the power tool towards you because of the risk of injury from contact with the rotating attachment. Make sure you always have a firm and secure footing. Be extremely cautious when changing direction with the power tool – especially on slopes. On slopes, always work parallel to the gradient to reduce the risk of injury from slipping or contact with the attachment. Never work on steep slopes because of the risk of injury through loss of control of the power tool. Special care must be taken when working in overgrown terrain. When clearing leaves, take care not to harm small animals. Be particularly alert and cautious when wearing ear protection because your ability to hear warnings (shouts, alarms, etc.) is impaired. Take breaks when you start getting tired or feeling fatigued – the risk of accidents! Work calmly and carefully – in daylight conditions and only when visibility is good. Proceed with caution, do not put others in danger. If your power tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work – see also “Before Starting”. Make sure the safety devices are working properly. Never use a power tool that is no longer safe to operate. In case of doubt, contact a dealer. Do not touch the attachment while the engine is running. If the attachment becomes jammed by an obstruction, switch off the engine immediately before attempting to remove the obstruction – otherwise, risk of injury! Opening the throttle while the attachment is blocked increases the load and reduces engine speed. The clutch then slips continuously and this causes overheating and damage to the import tant components (e.g. clutch, polymer housing components) – and this can increase the risk of injury from the attachment moving while the engine is idling. Check the sweeping attachments at regular short intervals during operation or immediately if there is a sudden change in behavior:

• Shut off the engine, hold the machine securely.
• Check condition and proper mounting.
• Replace damaged sweeping attachments immediately.

Clean the attachment and deflector at regular intervals during operation.

• Shut off the engine
• Use gloves
• Remove debris from between the sweeping attachments and from the area around the gearbox and deflector.

To reduce the risk of injury, shut off the engine before changing attachments.

After Finishing Work

After finishing work or before leaving the power tool unattended: Shut off the engine.

Maintenance and Repairs

Service the machine regularly. Do not attempt any maintenance or repair work not described in the MultiTool and MultiEngine instruction manual. Have all other work performed by a servicing dealer? STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. STIHL dealers are regularly given the opportunity to attend training courses and are supplied with the necessary technical information. Only use high-quality replacement parts in order to avoid the risk of accidents and damage to the power tool. If you have any questions in this respect, consult a servicing dealer. STIHL recommends the use of original STIHL replacement parts. They are specifically designed to match your model and meet your performance requirements. To reduce the risk of injury, always shut off the engine before carrying out any maintenance or repairs or cleaning the machine.
