STIHL KB-KM Bristle Brush Instruction Manual

STIHL KB-KM Bristle Brush

KombiSystem

In the STIHL KombiSystem a number of different KombiEngines and KombiTools can be com‐bined to produce a power tool. In this instruction manual the functional unit formed by the Kom‐biEngine and KombiTool is referred to as the power tool.
Therefore, the separate instruction manuals for the KombiEngine and KombiTool should be used together for the power tool.
Always read and and make sure you understand both instruction manuals before using your power tool for the first time and keep them in a safe place for future reference.

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.
• Both user manuals (KombiEngine and KombiTool) must be read through attentively before using the unit for the first time and kept in a safe place for future reference. Non-compliance with the user manuals may cause serious or even fatal injury. The machine should only be provided or loaned to people familiar with this model and its operation. The KombiEngine and KombiTool user manuals should always be handed over with the machine.
• Use the bristle brush only for sweeping areas and paths, including uneven and jointed surfaces, and natural stone paving.
• Use the sweeper drum assembly only for sweeping areas and paths, moving wet materials, such a leaves or dirt to a central point, clearing snow and removing standing water from solid surfaces.
• The machine must not be used for any other purposes – risk of accident!
• Only mount accessories that are explicitly approved for this power tool model by STIHL or are technically identical. If you have any questions about this, 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. 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 which 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 the machine by the carrying handle, sweeping attachment in front of you, hot muffler away from your body.
By vehicle: When transporting in a vehicle, properly 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 appropriate chapters in the KombiEngine and KombiTool user manuals:

• Tool: correctly fitted, secure and in perfect condition
• Both sweeping attachments must be mounted.
• Never attempt to modify the controls or safety devices.
• Inspect the deflectors for damage and wear. Do not operate the machine with a damaged deflector – replace damaged parts.
• Keep the handles dry and clean – free from oil and dirt – this is important for safe control of the machine.
• Adjust carrying harness and handles in accordance with body height. Observe the chapter “Fitting the Harness”

The power tool must only be operated when it is in good operating condition – Risk of accident!
If you use sweeping attachments, position the gearbox so that the axle is above the shaft.
To prepare for emergencies when using a harness: Practice setting down the machine quickly. To avoid damage, do not throw the machine to the ground when practicing.
Replace damaged sweeping attachments.
See also notes on “Before Starting” in the user manual of the KombiEngine you are using.

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 control handle, left hand on loop handle, even if you are left- handed.
To ensure reliable control, wrap your thumbs tightly around the control handle and handle.

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 ejected objects, do not allow any other persons within 5 meters of your own position. This distance must also be maintained in relation to objects (vehicles, window panes) – risk of property damage!
• The correct engine idle speed is important to ensure that the attachment stops moving when you let go of the throttle trigger. Check and correct the idle speed setting at regular intervals. If the sweeping attachment still rotates
• when the engine is idling, have your dealer check your machine and make proper adjustments or repairs – see KombiEngines user manual.
• Electrostatic charges may build up when working on synthetic surfaces – risk of electric shock and accidents!
• Take special care in slippery conditions – damp, snow, ice, on slopes or uneven ground!
• Watch out for obstacles: tree stumps, roots – risk of tripping or stumbling!
• Make sure you always have a firm and secure footing.
• 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 fatigue – 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. 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.
• 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.
• To reduce the risk of injury from thrown objects, never operate the unit without a properly mounted deflector designed specifically for the unit and the attachment. Check the work site – rocks, metal objects etc. may be caught up and ejected – risk of injury! Special care must be taken when working in overgrown terrain.
• When clearing leaves, take care not to harm small animals.
• 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.

Before you leave the machine: Shut the engine off.
Regularly clean the cutting attachment mounting and remove any blockages and material that has accumulated between the sweeping attachments or around the deflector.
To reduce the risk of injury, shut off the engine before changing attachments.
