SAFETY WARNINGS

General Power Tool Safety Warnings
(EN 60745-1:2009+A11:2010)
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.
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
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adap- ter plugs with earthed (groun- ded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with ear- thed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increa- sed risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water en- tering 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. Damaged or entangled cords in- crease 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 use reduces the risk of electric shock.
f) 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 elec- tric shock.
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.
b) Use personal protective equi- pment. Always wear eye protec- tion. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing pro- tection used for appropriate con- ditions will reduce personal inju- ries.
c) Prevent unintentional star- ting. 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 ener- gising power tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep pro- per footing and balance at all ti- mes. This enables better control of the power tool in unexpected situations.
f) 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.
g) 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.
h) 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 se- cond.
Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source and/or the battery pack from the power tool be- fore making any adjustments, changing accessories, or storing power tools. Such preventive sa- fety measures reduce the risk of starting the powertool accidenta- lly.
d) 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.
e) Maintain power tools. 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 acci- dents are caused by poorly main- tained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cut- ting tools with sharp cutting ed- ges are less likely to bind and are easier to control.
g) Use the power tool, acces- sories and tool bits etc. in accor- dance 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.
h) 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
a) Recharge only with the char- ger specified by the manufac- turer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
c) When battery pack is not in use, keep it away from other me- tal 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 ter- minals together may cause burns or a fire.
d) Under abusive conditions, li- quid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Li- quid ejected from the battery may cause irritation or burns.
Service
a) 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

Chain saw safety warnings (IEC 60745-2-13:2006+A1:2009)

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 hand- le and your left hand on the front handle. Holding the chain saw with a reversed hand configura- tion increases the risk of personal injury and should never be done.
Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring or its own cord. Saw cha- ins contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Wear safety glasses and hea- ring protection. Further protec- tive equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
Do not operate a chain saw in a tree. Operation of a chain saw while up in a tree may result in personal injury.
Always keep proper footing and operate the chain saw only when standing on fixed, secure and le- vel surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.
When cutting a limb that is un- der tension be alert for spring back. When the tension in the wood fibres is released the spring loaded limb may strike the ope- rator and/or throw the chain saw out of control.
Use extreme caution when cut- ting brush and saplings. The slen- der material may catch the saw chain and be whipped toward you or pull you off balance.
Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or sto- ring the chain saw always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
Follow instructions for lubrica- ting, chain tensioning and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chan- ce for kickback.
Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non-wood building materials. Use of the chain saw for opera- tions different than intended could result in a hazardous situation.
Do not attempt to fell a tree un- til you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while fe- lling a tree.
This chain saw is not intended for tree felling. Use of the chain saw for operations different than intended could result in serious injury to the operator or bystan- ders.

Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the guide bar tou- ches an object, or when the wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely ex- clusively upon the safety devices built into your saw. As a chain saw user, you should take seve- ral steps to keep your cutting jobs free from accident or injury. Kickback is the result of tool mi- suse and/or incorrect operating procedures or conditions and can be avoided by taking proper pre- cautions as given below:

Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.
Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situa- tions.
Only use replacement bars and chains specified by the manu- facturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.
Follow the manufacturer’s shar- pening and maintenance instruc- tions for the saw chain. Decrea- sing the depth gauge height can lead to increased kickback. Additional safety warnings for operation.
Always remove the battery pack before assembling, adjusting or cleaning, and before leaving the machine unattended for any pe- riod.
Checking the completeness, as- sembly and setting of the chain saw (see details below) before start to work. Repeat the checking regularly during your work.
It is recommended that the unex- perienced user should have prac- tical instruction in the use of the chainsaw and the protective equi- pment from an experienced ope- rator. The initial practice should be cutting logs on a saw horse or cradle.
This tool is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of expe- rience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
Children and juveniles, with the exception of apprentices older than 16 years and under super- vision, may not operate the chain saw. The same applies for persons who do not or do not sufficiently know how to handle the chain saw.
The operating instructions should always be ready to hand. Persons unfit or tired must not operate the chain saw.
Wait until the chain has come to a standstill completely before pla- cing it down.

Battery pack safety warnings

Never reach over the riving knife or under the base plate. There is a risk of injury!
Do not cut if the saw chain is in contact with the workpiece, is in the workpiece or may hit an object. This can lead to serious injuries.
Clamp loose workpieces before cutting them.
Remove foreign objects such as nails, screws, etc.
When cutting a branch that is under tension be alert for spring back. When the tension in the wood fibres is released, the spring-loaded limb may stri- ke the operator and/or throw the chainsaw out of control.
Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
When the saw chain is running, first place the base plate on the surface of the workpiece and let the saw cut on its own. Apply only light pressure to the saw. The chain speed should not be much slower.

Kickback

The shape of the riving knife largely eliminates the risk of kickback.
The saw is optimally protected against kickback by the riving knife with tip protection. Never remove the riving knife. There is a risk of injury!

Chain lubricating

You can use the Plastic Bottle included in the set to apply oil on the product.
Do not use engine oil, waste oil or other mineral oils.
If the saw makes a rattling noise, the chain must be lubricated.
The use of the chainsaw without lubricating the chain with chain oil will damage the saw chain and the guide bar.

How to remove the old chain and mount the new chain

Please remove the battery before extracting the chain.
Only handle the saw chain with gloves and remo- ve the battery first!
Inspect the saw chain and the guide bar for dama- ge or signs of wear.
Never put a new saw chain on a worn guide bar.
Let each new saw chain break-in first!
When attaching the saw chain, observe the run- ning direction!

Unscrew the head screw counter-clockwise in order to remove the sprocket cover. Turn the knob on the guide cover to align the guide adjustment screw post boss with the screw hole (Image A).
The adjusting screw boss on the guide plate cover is aligned with the guide plate hole position to install the guide plate cover (Image B).
When the knob is turned, the chain will be pulled down and loosened continuously. When the chain is loosened, it can rebound quickly.
Manually screw the screws into the bottom of the machine without tightening (Image C).
Use a wrench to loosen and remove the hex screws on the guide plate cover and to tighten the socket head cap screws (Image D).
The new chain will be stretched in the early stage of use. Please check and adjust to the appropriate tension frequently, because the loose chain is easy to derail, which may lead to rapid wear of the chain and guide plate.
Note: 1-3 middle guide teeth are exposed in the pulldown chain (Image E).
Remove the guide bar from the machine and run the saw chain around it. Please note the running direction of the saw chain. The saw chain icon is shown on the cover.
Run the saw chain over the sprocket and replace the guide bar on the chain adjusting screw pin.
Use an oiler to oil the saw chain and the sprocket. Slightly tighten the saw chain with the chain adjusting screw. Use the included adjustment key to tighten the screw. For tightening, turn the screw clockwise.
Retighten the sprocket cover with the head screw on the housing.

Adjusting saw chain tension

CAUTION: Do not tighten the saw chain too much.
Excessively high tension of saw chain may cause breakage of saw chain, wear of the guide bar and breakage of the sprocket.
CAUTION: A chain which is too loose can jump off the guide bar. The saw chain may become loose after use. From time to time check the saw chain tension, certainly before each use.

a. Remove the battery.
b. Loosen the head screw a bit to loosen the sproc- ket cover lightly.
c. Adjust the chain tension. Turn the chain head screw clockwise to tighten, turn it counter-clockwise to loosen.
Tighten the saw chain so that the gap between the center of the lower side of the guide bar and the saw chain becomes approximately 3 – 4 mm.
d. Tighten the head screw to secure the sprocket cover.

Sharpen the chainsaw

The saw teeth must be sharpened if the sawdust becomes powdery, if additional force is required for the incision, if a straight incision is no longer possible or if the vibrations become stronger.
Blunt saw chains should be re-sharpened.
To sharpen the chain use a chain sharpener, make sure you sharpen the chain at a 30° angle.
Or have the chain re-sharpened professionally (advised).
Replace the saw chain if there is considerable da- mage that cannot be repaired by filing.

CLEANING AND MAINTENANCE

Make sure the product is turned off and unplugged from power.
Remove the rechargeable battery.

Thoroughly clean the notch of the guide bar. Repla- ce the guide bar if the guide groove is damaged or worn and the saw chain has too much lateral space. For best performance, always keep the saw blade and the chainsaw in good order. Remove the battery pack from the tool before carrying out any adjustment, servicing or maintenance.

Clean the sprocket area with a brush or compressed air.
