General Power Tool Safety Warnings
WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.
Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators.
  There is an increased risk of electric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions.
  Water entering a power tool will increase the risk of electric shock.

• 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.
  Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use.
  Use of a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
  Use of an RCD reduces the risk of electric shock.

Personal safety

• 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.

• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.

• 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.

• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts.
  Loose clothes, jewellery or long hair can be caught in moving parts.

• 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.

• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

Power tool use and care

• Do not force the power tool. 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.

• 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.

• Disconnect the plug from the power source and/or remove the battery pack, if detachable, 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.

• 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.

• Maintain power tools and accessories. 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.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• 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.

• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

• Recharge only with the charger specified by the manufacturer.
  A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

• Use power tools only with specifically designated battery packs.
  Use of any other battery packs may create a risk of injury and fire.

• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another.
  Shorting the battery terminals together may cause burns or a fire.

• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, addi-tionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

• Do not expose a battery pack or tool to fire or excessive temperature.
  Exposure to fire or temperature above 130 °C may cause explosion.

• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and  increase the risk of fire.

Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

General Chain Saw Safety Warnings

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause  entanglement of your clothing or body with the saw chain.

• Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle.
  Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.

• Hold the chain saw by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a “live” wire may make exposed metal parts of the chain saw “live” and could give the operator an  electric shock.

• Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw chain.

• Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.

• Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface.

• Slippery or unstable surfaces may cause a loss of balance or control of the chain saw.

• When cutting a limb that is under tension be alert for spring back. When the tension in the wood fibres is released the spring loaded limb may strike the operator and/or throw the chain saw out of control.

That the declared vibration total value(s) and the declared noise emission value(s) have been measured in accordance with a standard test method and may be used for comparing one machine with another.
That the declared vibration total value(s) and the declared noise emission value(s) may also be used in a preliminary assessment of exposure.
That the vibration and noise emissions during actual use of the machine can differ from the declared total value depending on the ways in which the machine is used; and of the need to identify safety measures to protect the operator that  are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle  such as the times when the machine is switched offand when it is running idle in addition to the trigger time).

Assembly

For Your Safety

• Warning! Switch off and remove battery from power tool before adjusting or cleaning.
• Caution! Do not touch the rotating chain.
• Do not operate the chain saw near other people, children or animals. Do not operate the chain saw after drinking alcohol or under the influence of intoxicating drugs or medication.

Mounting and Tensioning the Saw Chain (see figures B1 – B4)

• Do not use any tools for assembly.
• Check the chain tension regularly during use. Using the chainsaw with a misaligned or incorrectly tensioned chain can result in chain breakage, kickback and/or injury.
• Upon initial operation, new chains can lengthen considerably.
• Avoid tensioning the chain if it is hot, as this will cause the chain to become overtensioned and fit too tightly against the chain bar when it cools down.
  – Place the chain saw on any suitable flat surface.
  – With the chain bar off the tool, make sure that the affixed tensioning wheel (14) on the chain bar has been fully rotated anticlockwise.
  – Slide the saw chain (13) in the slot around the chain bar (12).
  – Ensure the saw chain is in the correct running direction by comparing the saw chain with the rotation symbol (11).
  – Fit the chain links around the drive sprocket (3) and mount the chain bar (12) onto the fastening bolt (9).
  – Check if all parts are seated properly and hold the chain bar and the chain in this position.
  – Then rotate the affixed tensioning wheel (14) clockwise until the chain is partly tensioned and will stay mounted to the chain saw.
  – Attach the cover (17) and rotate the clamping knob (16) clockwise until the cover is partly secured.
  – Turn the chain-tensioning ring (15) clockwise until the correct chain tension is reached. When adjusting with the chain-tensioning ring (15), make sure to hold the clamping knob (16) to prevent it from turning and clamping too early.
  – The saw chain (13) is correctly tensioned when it can be raised approx. 6−7 mm from the chain bar in the centre.
  This should be done by using one hand to raise the saw chain against the weight of the machine.
  – Once the correct tension is reached, hold the chain-tensioning ring (15) and rotate the clamping knob (16)  clockwise until it is firmly secured.
  – If the chain is tensioned too tightly, unscrew the clamping knob (16) and repeat the steps for tensioning.
  – The locking mechanism of the clamping system prevents  the chain from loosening. If the chain-tensioning ring (15)is hard to rotate, loosen the clamping knob (16) by turning it anticlockwise.
  Saw Chain Lubrication (see figure C)
  Note: The chain saw is not supplied filled with oil. It is essential to fill with oil before use. Operating the chain saw without chain oil or when the oil level is below the minimum mark will result in damage to the chain saw.

Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain is automatically lubricated with chain oil during operation via the oil outlet (7).
Filling the oil reservoir:

• Set chain saw on any suitable surface with the oil filler cap (19) facing upward.
• Clean area around the oil filler cap (19) with a cloth and unscrew the cap.
• Add Bosch biodegradable chain saw oil until the oil level can be viewed through the oil tank opening (25). Take care when filling to avoid dirt or debris from entering the oil tank. Screw on oil filler cap (19) again and tighten fully.
  Note: It is important to use only readily biodegradable chain lubricants (according to RAL-UZ 48) to avoid damage to the chain saw. Never use recycled/old oil. Use of non approved oil will invalidate the warranty.
  Note: The oil filter is embedded inside the oil tank. Contact the Bosch service centre for cleaning or troubleshooting.
  Note: It is strongly recommended to use Bosch Biodegradable chain oil. This can be seen in the accessories section.
  Note: Oil becomes denser at lower temperatures which decreases the flow rate of oil.

Starting Operation

Inserting/removing the battery (see figure D)
Note: Using unsuitable batteries can lead to malfunctions or damage the machine.
Insert the charged battery (21). Make sure that the battery is fully fitted.
To remove the battery (21) from the machine, press the battery unlockin button (22) and pull the battery out.
Charging the Battery

• Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the charger.
  The battery is equipped with temperature monitoring that allows charging only in the temperature range between 0 °C and 35 °C. In this manner, a high battery service life is  achieved.

Note:
The battery is supplied partially charged. To ensure full battery capacity, completely charge the battery in the battery charger before using for the first time.
The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging  procedure does not cause damage to the battery.
The “Electronic Cell Protection (ECP)” protects the lithiumion battery against deep discharging. When the battery is empty, the product is switched off by means of a  protective circuit: The product no longer operates.
Do not continue to press the On/Off switch after an automatic shut-off of the product. The battery could become damaged.

Operation

• Always read the operating and safety information before use.
• Always check the tool and chain condition, the oil level and correct assembly before use. Only use the chain saw if it is in perfect condition.
• Always wear suitable clothing and personal protective equipment.
• Always make sure that the environment is dry and free from obstacles and persons not involved.
• Never use the chain saw on a ladder or above shoulder height.
• Never over-reach or work with arms fully extended.
• Always hold the chain saw firmly with both hands.
  The saw chain is automatically lubricated with chain oil during operation via the oil outlet (7).
  The chain saw is not supplied filled with oil.
  Be sure to fill the chain saw with chain oil before using it.
  It is important to use only biodegradable chain lubricants (according to RAL- UZ 48) to avoid damage to the chain saw.
  The recommended Bosch biodegradable chain saw oil can be found in the accessories.
  Filling the oil reservoir: (see figure C)
  – Set the chain saw on any suitable surface with the oil filler cap (19) facing upward.
  – Clean the area around the oil filler cap (19) with a cloth and unscrew the cap.
  – Add Bosch biodegradable chain saw oil until the oil level can be viewed through the oil tank opening (25). You can check the oil level through the viewing window (25) during operation. When the minimum level is reached, top up with new oil.

Switching On and Off (see figure E1)

• Pull the hand guard/activation lever for the kickback brake (5) from position ➋ to position ➊ towards the front handle (4). If the hand guard/activation lever for the kickback brake (5) has not been moved, then the kickback brake  has not been deactivated before use and the chain saw will not start.
• Always push the hand guard/activation lever for the kickback brake forward to the deactivated position after each use.
  – Remove the chain guard (18).
  – Hold the chain saw as shown in figure E2.
  – Pull the activation lever for the kickback brake (5) backwards to the front handle.
  – To start the machine, first push the lock-off button for the On/Off switch (20) and then press the On/Off switch  (2) and keep it pressed. When the machine is running, the lock-off button can be released again.
  – To switch off the power tool, release the On/Off switch (2).
  – The kickback brake is a safety mechanism activated by the wrist through the front hand guard (5) when kickback occurs. The chain stops immediately. This reduces the risk of kickback injury. Try to avoid kickback.
  – Periodically push the activation lever for the kickback brake (5) forward during operation to test the function of the kickback brake. Stop operation immediately if the chain saw does not stop immediately.
  Note: Do not stop the chain saw after sawing by actuating the kickback brake (5).

Checking the Lubrication (see figure E3)

• Tilt the chain saw so that the chain bar is 20 cm away from a sheet of paper lying on the ground.
• Switch on the chain saw and let it run for approx.
  1 minute until oil splashes can be seen on the sheet of paper to confirm that oil is being pulled through the automatic lubrication  system.
  Note: Operating the chain saw without chain oil or when the oil level is below the minimum mark will result in damage to the chain saw.
  Note: Oil becomes denser at lower temperatures, which decreases the flow rate of oil.
  Note: Saw chain life and cutting capacity depend on optimum lubrication.

General Behaviour (see figure F)
– First-time users should practise cutting logs on a saw horse.
– Hold the chain saw at the right-hand side of your body.
– Use the metal spiked bumper (10) as a leverage point while cutting.
– The chain must be running at full speed before it makes contact with the wood.
– Reset the metal spiked bumper at a lower point when sawing thicker logs or tree trunks. For this, pull the chain saw slightly backwards until the metal spiked bumper release, and reposition at lower level to continue sawing.
Do not remove the chain saw completely out of the cut.
– Do not force the saw chain while cutting, let the chain do the work.
– Always remove the chain saw from a wood cut while the saw chain is running.
– Beware when reaching the end of the cut. The weight of the chain saw changes unexpectedly as it cuts free from the wood. Danger of injury to the legs and feet.
Kickback (see figure G)
– Kickback is the sudden backward/upward motion of the chain saw, occurring when the chain (at the tip of the chain bar) comes in contact with a log or wood, or when the chain becomes jammed.
– When kickback occurs, the chainsaw reacts unpredictable and can cause heavy injuries to the operator or bystanders.
– Particular attention must be given when sawing sidewards, slanted or during length cuts, as the metal spiked bumper (10) usually can not be applied.
Cutting Logs (see figures H)
– Always secure the logs before cutting.
– Always cut the logs beyond the secured points to prevent the log from closing in and causing the chain to get jammed.
– Never allow the saw chain to make contact with the ground or cutting equipment.
– Be careful not to trip over tree stumps, branches, roots, etc.
Cutting Wood under Tension (see figure I)
– Be extremely careful when sawing wood, branches or trees under tension. Leave saw jobs like these to trained professionals. There is a high risk of accidents.
Limbing a Branch or Tree (see figure J)
– Limbing is removing the small branches from a fallen tree or large branch.
– Leave larger lower limbs to support the log off the ground.
– Remove the smaller limbs in one cut.
