Safety instructions

General power tool safety warnings
Warning! Read all safety warnings and all instructions. Failure to follow the warnings and 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 all of the warnings listed below refers to your mains operated (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 adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b. 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.
c. Do not expose power tools to rain or wet conditions. Water entering 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 increase 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 electric shock.
3. 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 equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. 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.
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 proper footing and balance at all times. 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.
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 before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
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 tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g. 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.
Battery tool use and care
a. 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.
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 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.
d. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
6. 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.

Additional power tool safety warnings

Warning! Additional safety warnings for chainsaws

Keep all parts of the body away from the saw chain when the chainsaw is operating. Before you start the chainsaw, 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 chain saw.
Always hold the chainsaw with your right hand on the rear handle and your left hand on the front handle. Holding the chainsaw with a reversed hand configuration 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. Saw chains 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 hearing protection. Further protective 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 chainsaw in a tree. Operation of a chainsaw 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 level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chainsaw.
When cutting a limb that is under tension be alert for spring back. When the tension in the wood fibers is released the spring loaded limb may strike the operator and/or throw the chain saw 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.
Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chainsaw 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 lubricating, chain tensioning and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance 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 chainsaw for purposes not intended. For example: do not use the chainsaw for cutting plastic, masonry or non-wood building materials. Use of the chainsaw for operations different than intended could result in a hazardous situation.

Causes and operator prevention of kickback
Kickback may occur when the nose or tip of the guide bar touches 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 chainsaw which could result in serious personal injury.
Do not rely exclusively upon the safety devices built into your chainsaw.
As a chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury.
Kickback is the result of tool misuse and / or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

Maintain a firm grip, with thumbs and fingers encircling the chainsaw handles. With both hands on the chainsaw, 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 chainsaw.
Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chainsaw in unexpected situations.
Only use replacement guide bars and chains specified by the manufacturer. Incorrect replacement guide bars and chains may cause chain breakage and/ or kickback.
Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.
Striking metal, cement or any other hard material near the wood, or buried in the wood can cause kickback.
A dull or loose chain can cause kickback.
Do not try to insert into a previous cut. As this could cause kickback. Make a fresh cut every time.

Safety recommendations for the chainsaw

We strongly recommend that first time users obtain practical instruction in the use of the chainsaw and protective equipment from an experienced user. Initial practice should be completed sawing logs on a saw horse or cradle.
We recommend that when carrying the chainsaw that you remove the battery and make sure that the saw chain is facing backwards.
Maintain your chainsaw when not in use. Do not store your chainsaw for any length of time without first removing the saw chain and guide bar which should be kept immersed in oil. Store all parts of your chainsaw in a dry, secure place out of reach of children.
We recommend you drain the oil reservoir prior to storage. u Be sure of your footing and pre-plan a safe exit from a falling tree or branches.
Use wedges to help control felling and prevent binding the guide bar and saw chain in the cut.
Saw chain care. Keep the saw chain sharp and snug on the guide bar. Ensure the saw chain and guide bar are clean and well oiled. Keep handles dry, clean and free from oil and grease.

Avoid cutting

Prepared timber.
Into the ground.
Into wire fences, nails. etc.

Additional safety instructions

Ensure someone is nearby (but at a safe distance) in case of an accident.
If for any reason you have to touch the saw chain, make sure your chainsaw is disconnected from the mains.
The noise from this product can exceed 85 dB(A). We therefore recommend you take appropriate measures for the protection of hearing.
When handling the product the chain bar may become hot, handle with care.

Place the chainsaw onto a stable surface (fig. A).
Fully loosen the chain adjust locking knob (9) (fig. B).
Remove the chain cover assembly (10) (fig. C).
Turn the tension adjust ring (5) anti-clockwise as far as it will go so the arrow on the tension adjust ring (5) lines up with the marker on the chain cover assembly (13) (fig. D)
Place the chain (6) over the guide bar (7) making sure that the saw chain cutters on the upper part of the guide bar (7) face towards the front (fig. E).
Guide the chain (6) around the guide bar (7) and pull it to create a loop to one side at the rear end of the guide bar (7).
Guide the chain (6) around the drive sprocket (14). Place the guide bar (7) onto the bar location studs (15) (fig. F & G).
Place the chain cover assembly (10) onto the chainsaw (fig. H) making sure the arrows are aligned (fig. I).
Turn the chain adjust locking knob (9) clockwise to attach the chain cover assembly (10) and lightly tighten (fig. I).
Turn the chain adjust locking knob (9) 180 degrees anticlockwise to release the tension (fig J).
Turn the chain tension adjust ring (5) clockwise until the chain (6) is tight. Make sure that the chain (6) is snug around the guide bar (7) (fig. K).
Check the tension as described below. Do not overtighten.
Tighten the chain adjust locking knob (9) (L).

Checking and adjusting the chain tension (fig. K)
Before use and after every 10 minutes of use, you must check the chain tension.

Remove the battery (12).
Lightly pull on the chain (6) as shown (inset fig. K). The tension is correct when the chain (6) snaps back after being pulled 3 mm away from the guide bar (7). There should be no “sag” between the guide bar (7) and the chain (6) on the underside.

Note: Do not over-tension the chain as this will lead to excessive wear and will reduce the life of the guide bar and the chain.
Note: When the chain is new, check the tension frequently (after disconnecting from the mains) during the first 2 hours of use because a new chain stretches slightly.
To increase the tension (fig. J, K & L)

Turn the chain adjust locking knob (9) 180 degrees anticlockwise to release the tension. (fig.J)
Tension the chain using the chain tension adjusting ring (5), turn clockwise to tighten (fig K).

To fit the battery (12), line it up with the receptacle on the tool. Slide the battery into the receptacle and push until the battery snaps into place.
To remove the battery, push the release buttons (16) while at the same time pulling the battery out of the receptacle.

Use

Warning! Let the tool work at its own pace. Do not overload.
Charging the battery (fig. N)
The battery needs to be charged before first use and whenever it fails to produce sufficient power on jobs that were easily done before.
The battery may become warm while charging; this is normal and does not indicate a problem.
Warning! Do not charge the battery at ambient temperatures below 10 °C or above 40 °C. Recommended charging temperature: approx. 24 °C.
Note: The charger will not charge a battery if the cell temperature is below approximately 10 °C or above 40 °C.
The battery should be left in the charger and the charger will begin to charge automatically when the cell temperature warms up or cools down.

To charge the battery (12), insert it into the charger (19). The battery will only fit into the charger in one way. Do not force. Be sure that the battery is fully seated in the charger.
Plug in the charger and switch on at the mains.

The charging indicator (18) will blink.
The charge is complete when the charging indicator (18) switches to continuously on. The charger and the battery can be left connected indefinitely. The charging indicator will switch on as the charger occasionally tops up the battery charge.

Charge discharged batteries within 1 week. Battery life will be greatly diminished if stored in a discharged state.

Leaving the battery in the charger
The charger and battery pack can be left connected with the charging indicator glowing indefinitely. The charger will keep the battery pack fresh and fully charged.
Charger diagnostics
If the charger detects a weak or damaged battery, the charging indicator (18) will flash red at a fast rate. Proceed as follows:

Re-insert the battery (12).
If the charging indicators continues flashing red at a fast rate, use a different battery to determine if the charging process works properly.
If the replaced battery charges correctly, the original battery is defective and should be returned to a service center for recycling.
If the new battery gives the same indication as the original battery, take the charger to be tested at an authorized services center.

Note: It may take as long as 30 minutes to determine that the battery is defective. If the battery is too hot or too cold, the charging indicator will alternately blink red, fast and slow, one flash at each speed and repeat.
Filling the oil reservoir (fig. O)

Remove the oil cap (3) and fill the reservoir with the recommended chain oil. You can see the oil level in the oil level indicator (11). Refit the oil cap (3).
Periodically switch off and check the oil level indicator (11); if it is less than a quarter full, remove the battery from the chainsaw and refill with the correct oil.

Oiling the chain
We recommend that you use only Black & Decker oil during the lifetime of your chainsaw because mixtures of different oils could lead to the oil becoming degraded, which can drastically shorten the lifetime of the saw chain and create additional risks.
Never use waste oil, thick oil or very thin sewing machine oil.
These may damage your chainsaw.
The saw chain (6) must be oiled before each use and after cleaning using only the correct grade of oil (cat. no. A6023QZ).

Lubricate the saw chain (6) by slowly pressing the bulb (17) (fig. O) on the oil cap (3) four time before making each cut. Hold the bulb down for 1 second each time.

Switching on (fig. O)

Grip your chainsaw firmly with both hands. Pull the lock-off button (2) with your thumb and then push the on/off switch (1) to start.
When the motor starts, remove your thumb from the lockoff button (2) and grip the handle firmly.

Do not force the tool, allow the tool to do the work. It will do a better and safer job at the speed for which it is designed. Excessive force will stretch the saw chain (6).
If the saw chain (6) or guide bar (7) becomes jammed

Switch the tool off.
Remove the battery (12).
Open the cut with wedges to relieve the strain on the guide bar (7). Do not try to wrench the chainsaw free.
Start a fresh cut.

Felling (fig. P, Q & R)
Inexperienced users should not attempt to fell trees. The user may suffer injury or cause damage to property as a result of failure to control the direction of fall, the tree may splinter or damaged/dead branches may fall during cutting.
The safe distance between a tree to be felled and bystanders, buildings and other objects is at least 2 1/2 times the height of the tree. Any bystander, building or object within this distance is at risk from being struck by the tree when felled.
Before attempting to fell a tree:

Make sure that there are no local by-laws or regulations that would prohibit or control the felling of the tree.
Consider all conditions that may affect the direction of fall, including:
The intended direction of fall.
The natural lean of the tree.
Any unusual heavy limb structure or decay.
Surrounding trees and obstacles including overhead lines and underground drains.
The wind speed and direction.

Pre-plan a safe exit from falling trees or branches. Make sure that the exit route is clear of obstacles that would prevent or hinder movement. Remember that wet grass and freshly cut bark is slippery.

Do not attempt to fell trees where the tree diameter is greater than the cutting length of the chainsaw.
Cut a direction notch to determine the direction of fall.
Make a horizontal cut to a depth of between 1/5th and 1/3rd of the diameter of the tree, perpendicular to the line of fall at the base of the tree (fig. P).
Make a second cut from above to intersect with the first and make a notch of about 45°.
Make a single horizontal felling cut from the other side 25 mm to 50 mm above the centre of the direction notch. (fig. Q). Do not cut through to the direction notch, you could lose control of the direction of fall.
Drive a wedge or wedges into the felling cut to open it and drop the tree (fig. R).

Pruning trees
Make sure that there are no local by-laws or regulations that would prohibit or control the pruning of the tree limbs. Pruning should only be undertaken by experienced users there is an increased risk of the saw chain pinching and kick back.
Before pruning consideration should be given to conditions affecting the direction of fall including:

The length and weight of the branch to be cut.
Any unusual heavy limb structure or decay.
Surrounding trees and obstacles including overhead.
The wind speed and direction.
The branch being intertwined with other branches.

The operator should consider access to the tree limb and the direction of fall. The tree branch is liable to swing towards the tree trunk. In addition to the user bystanders, objects and property below the branch will be at risk.

To avoid splintering, make the first cut in an upward direction to a maximum depth of one third the diameter of the branch.
Make the second cut downwards to meet the first.

Logging (fig. S, T & U)
How you should cut depends on how the log is supported.
Use a saw horse whenever possible. Always start a cut with the saw chain running and the spiked bumper (20) in contact with the wood (fig. S). To complete the cut use a pivoting action of the spiked bumper against the wood.
When supported along its whole length:

Make a downward cut, but avoid cutting the earth as this will blunt your saw chain quickly.

When supported at both ends:

First, cut one third down to avoid splintering and second, cut up to meet the first cut.

When supported at one end:

First cut one third up to avoid splintering and second, cut down to prevent splintering.

When on a slope:

Always stand on the uphill side.

When attempting to cut a log on the ground (fig. T):

Secure the workpiece using chocks or wedges. The user or a bystander should not steady the log by sitting or standing on it. Make sure that the saw chain does not contact the ground.

When using a saw horse (fig. U):
This is strongly recommended whenever possible.

Position the log in a stable position. Always cut on the outside of the saw horse arms. Use clamps or straps to secure the workpiece.

Limbing (fig. V)
Removing the branches from a fallen tree. When lambing, leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut. Branches under tension should be cut from the bottom of the branch towards the top to avoid binding the chain saw.
Trim limbs from opposite side keeping tree stem between you and saw. Never make cuts with saw between your legs or straddle the limb to be cut.
