DANGER!

When using the equipment, a number of safety precautions must be observed to avoid injuries and damage. Please read the complete operating instructions and safety information with due care. Keep these operating instructions in a safe place so that the information is available at all times. If you give the equipment to any other person, hand over these operating instructions and the safety information as well. We cannot accept any liability for damage or accidents which arise due to failure to follow these instructions and the safety information.

1. Safety information

DANGER! Read all the safety information and instructions. Failure to adhere to the safety

information and instructions set out below may result in electric shock, ﬁ re and/or serious injury. Keep all the safety information and

instructions in a safe place for future use.

General safety information for power tools

The term “power tool“ used in the safety regulations refers to power tools operated from the mains power supply (with a power cable) and to battery operated power tools (without a power cable).

1) Work area safety a) Keep work area clean and well lit.

Cluttered and dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of

ﬂ ammable 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.

2) 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. Unmodiﬁ ed 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 ground fault circuit interruptor (GFCI) protected supply. Use of an GFCI 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 inﬂ uence 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 ﬁ nger on

the switch or energizing 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, jewelery 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 these devices 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 second.

4) 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 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.

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 and accessories.

Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aﬀ ect the power tool’s 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 and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed.

Use of the power tool for operations diﬀ erent from 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.

5) Battery tool use and care a) Recharge only with the charger speciﬁ ed

by the manufacturer. A charger that is

suitable for one type of battery pack may create a risk of ﬁ re when used with another battery pack.

b) Use power tools only with speciﬁ cally

designated battery packs. Use of any other

battery packs may create a risk of injury and ﬁ re.

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 ﬁ re.

d) Under abusive conditions, liquid may be

ejected from the battery; avoid contact. If contact accidentally occurs, ﬂ ush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the

battery may cause irritation or burns.

e) Do not use a BATTERY pack or tool that

is damaged or modiﬁ ed. Damaged or

modiﬁ ed batteries may exhibit unpredictable behavior resulting in ﬁ re, EXPLOSION or risk of injury.

f) Do not expose a BATTERY pack or tool to

ﬁ re or excessive temperature. Exposure to

ﬁ re or temperature above 266°F (130°C) may cause explosion.

g) Follow all charging instructions and do

not charge the BATTERY pack or tool outside the temperature range speciﬁ ed in the instructions. Charging improperly or

at temperatures outside the speciﬁ ed range may damage the BATTERY and increase the risk of ﬁ re.

6) Service a) Have your power tool serviced by a

qualiﬁ ed repair person using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

b) Never service damaged BATTERY packs.

Service of BATTERY packs should only be

performed by the manufacturer or authorized service providers.

Additional safety instructions

We pay a great deal of attention to the design of every battery pack to ensure that we supply you with batteries which feature maximum power density, durability and safety. The battery cells have a wide range of safety devices. Each individual cell is initially formatted and its electrical characteristic curves are recorded. These data are then used exclusively to be able to assemble the best possible battery packs.

Despite all the safety precautions, caution must always be exercised when handling batteries. The following points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are used. Incorrect handling can cause cell damage.

Caution! Analyses conﬁ rm that incorrect use and

poor care are the main causes of the damage caused by high performance batteries.

Information about the battery

1. The battery pack supplied with your cordless tool is not charged. The battery pack has to be charged before you use the tool for the ﬁ rst time.

2. For optimum battery performance avoid low discharge cycles. Charge the battery pack frequently.

3. Store the battery pack in a cool place, ideally at 59°F (15°C) and charged to at least 40%.

4. Lithium-Ion batteries are subject to a natural ageing process. The battery pack must be replaced at the latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable of meeting the high power requirements and therefore pose a safety risk.

5. Do not throw battery packs into an open ﬁ re. There is a risk of explosion!

6. Do not ignite the battery pack or expose it to ﬁ re.

7. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common cause of deep discharge is lengthy storage or non-use of partly discharged batteries. Stop working as soon as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack in storage only after it has been fully charged.

8. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside the battery housing without this overheating actually being apparent externally.

9. Avoid damage and shocks. Replace batteries which have been dropped from a height of more than one meter or which have been exposed to violent shocks without delay, even if the housing of the battery pack appears to be undamaged. The battery cells inside the battery may have suﬀ ered serious damage. In this respect, please also read the waste disposal information.

10. If the battery pack suﬀ ers overloading and overheating, the integrated protective cutoﬀ will switch oﬀ the equipment for safety reasons. Caution! Do not press the ON/OFF switch any more if the protective cut-oﬀ has actuated. This may damage the battery.

11. Use only original battery packs. The use of other batteries may result in injuries, explosion and a ﬁ re risk.

12. Protect your rechargeable battery against moisture, rain and high humidity. Moisture, rain and high humidity can cause dangerous cell damage. Never charge or work with batteries which have been exposed to moisture, rain or high humidity – replace them immediately.

13. If your equipment is ﬁ tted with a detachable battery, remove the battery for safety reasons after you have ﬁ nished your work.

Information on chargers and the charging process

1. Please check the data marked on the rating plate of the battery charger. Be sure to connect the battery charger to a power supply with the voltage marked on the rating plate. Never connect it to a diﬀ erent mains voltage.

2. Protect the battery charger and its cable from damage and sharp edges. Have damaged cables repaired without delay by a qualiﬁ ed electrician.

3. Keep the battery charger, batteries and the cordless tool out of children‘s reach.

4. Do not use damaged battery chargers.

5. Do not use the supplied battery charger to charge other cordless tools.

6. In heavy use the battery pack will become warm. Allow the battery pack to cool to room temperature before commencing with the charging.

7. Do not over-charge batteries. Do not

exceed the maximum charging times. These charging times apply only to discharged batteries. Frequent insertion of a charged or partly charged battery pack will result in over-charging and cell damage. Do not leave batteries in the charger for more than 48 hours.

8. Never use or charge batteries if you

suspect that the last time they were charged was more than 12 months previously. There is a high probability

that the battery pack has already suﬀ ered dangerous damage (exhaustive discharge).

9. Charging batteries at a temperature below 50°F (10°C) will cause chemical damage to the cell and may cause a ﬁ re.

10. Do not use batteries which have heated during the charging process, as the battery cells may have suﬀ ered dangerous damage.

11. Do not use batteries which have suﬀ ered curvature or deformation during the charging process or which show other non-typical symptoms (gassing, hissing, cracking,…).

12. Never fully discharge the battery pack (recommended depth of discharge max. 80%) A complete discharge of the battery pack will lead to premature ageing of the battery cells.

13. Never charge the batteries unsupervised.

Protection from environmental inﬂ uences

1. Wear suitable work clothes. Wear safety goggles.

2. Protect your cordless tool and the battery charger from moisture and rain. Moisture and rain can cause dangerous cell damage.

3. Do not use the cordless tool or the battery charger near vapors and inﬂ ammable liquids.

4. Use the battery charger and cordless tools only in dry conditions and an ambient temperature of 50°F to 104°F (10°C to 40°C).

5. Do not keep the battery charger in places where the temperature is liable to reach over 104°F (40°C). In particular, do not leave the battery charger in a car that is parked in the sunshine.

6. Protect batteries from overheating. Overloads, over-charging and exposure to direct sunlight will result in overheating and cell damage. Never charge or work with batteries which have been overheated – replace them immediately if possible.

7. Storage of batteries, battery chargers and cordless tools. Store the charger and your cordless tool only in dry places with an

ambient temperature of 50°F to 104°F (10°C to 40°C). Store the Lithium-Ion rechargeable battery in a cool and dry place at 50°F to 68°F (10°C to 20°C). Protect them from humidity and direct sunlight! Place only fully charged batteries in storage (charged at least 40%).

8. Prevent the Lithium-Ion battery pack from freezing. Battery packs which were stored below 32°F (0°C) for more than 60 minutes must be disposed of.

9. When handling batteries beware of electrostatic charge: Electrostatic discharges cause damage of the electronic protection system and the battery cells. Avoid electrostatic charging and never touch the battery poles.

Battery Caution + Disposal

Disposal

Should your appliance need replacement after extended use, do not dispose of it with the household refuse, but in an environmentally safe way.

Waste produced by electrical machine items should not be handled like normal household rubbish. Please recycle where recycle facilities exist. Check with your local

authority or retailer for recycling advice. Always dispose of your battery pack according to federal, state, provincial and local regulations. Contact a recycling agency in your area for recycling locations.

 CAUTION! Even discharged battery packs

stops when the chain brake is applied.

6. Switch the motor oﬀ before setting the chain saw down.

7. When cutting a branch that is under tension, watch out for possible kickback when the tension of the wood is suddenly released.

8. All the maintenance of the chain saw, apart from the points indicated in these operating and maintenance instructions, is allowed to be carried out only by authorized service centers.

9. Install the chain saw guard over the chain bar when transporting and storing the chain saw.

10. USE ONLY SUITABLE SAW MATERIAL: Only cut wood. Do not use the chain saw for work for which it is not suited. Do not use the chain saw to cut plastic, masonry or materials not used for construction.

11. Important: National regulations diﬀ er in some countries and might restrict the use of the machine.

12. To detect signiﬁ cant damage or defects, the equipment must be inspected before use and each time after being dropped or suﬀ ering other shocks.

13. If any chain saw oil is spilled while ﬁ lling the oil tank, the equipment must be cleaned to remove the spilled chain saw oil.

Kickback can occur if the tip of the chain bar (chain sprocket) touches an object or the chain saw gets trapped in the wood while cutting. If the tip of the bar touches something, the chain bar could be catapulted upward at lightning speed back toward the operator. If the chain saw gets trapped along the top side of the chain bar, the chain bar could likewise be catapulted back to the operator quickly. In both cases you could lose control over the saw and suﬀ er serious injury. You should not rely solely on the integrated safety features of the chain saw. As a chain saw user, you must take note of a number of points if you are to be able to perform the work without suﬀ ering an accident or injury.

1. A proper understanding of kickbacks can reduce or preclude the element of surprise. Sudden, unforeseen reactions contribute to accidents.

2. Hold the saw ﬁ rmly with both hands while the motor is running, the right hand holding the rear handle and the left hand holding the front handle. Fingers and thumbs should be wrapped around the handles of the chain saw. A ﬁ rm grip will help you absorb kickbacks and

keep control over the saw. Do not let go.

3. Make sure that the area in which you are cutting is free of obstacles. The tip of the chain bar must not touch any tree trunk, branch or the like while the saw is cutting.

4. Cut at a high motor speed.

5. Do not bend too far forward or cut above shoulder height.

6. Sharpen and maintain the chain saw in accordance with the manufacturer's instructions.

7. Use only replacement bars and chains that are recommended and approved by the manufacturer.

8. If the equipment becomes jammed when cutting, switch it oﬀ immediately and free it carefully. Finally, check the equipment for damage (e.g. a bent chain bar) and carry out a test run.

9. It is not possible to exclude risk to health due to oil spray and wood dust.

10. Wearing gloves will help to reduce vibrations.

11. Keep the chain saw in good working order.

Persons using the chain saw for tree care, who are working up high with a rope and harness, must never work alone. A person working on the ground, who is trained in appropriate emergency procedures, must be present and assist the chain saw user.

Users must have training in general, safe climbing and work positioning techniques and be equipped with harness, rope, slings, carabiners and other equipment in order to maintain safe, correct working positions for themselves and for the saw.

The person working on the ground must check the saw, start the saw, allow it to warm up and shut it oﬀ again before it is raised up to the user in the tree.

The chain saw must be equipped with an appropriate sling so that it can be attached to the user’s harness (Fig. 22). a) The sling must be secured to the attachment

point on the rear of the saw,

b) suitable carabiners must be provided in

order to secure the saw to the user’s harness indirectly (i.e. through the sling) and directly (i.e. on the attachment point of the chain saw),

c) care must be taken to ensure that the chain

saw is attached securely when it is pulled up to the user, and

- 12 -

Anl_Fortexxa_18_20_SPK7_USA.indb 12Anl_Fortexxa_18_20_SPK7_USA.indb 12 29.11.2022 14:42:4329.11.2022 14:42:43

d) the chain saw must be secured to the harness

before it is released from the rope.

The chain saw must always be shut oﬀ when it is attached directly to the harness.

The chain saw is allowed to be attached only to recommended suspension ﬁ xtures on the harness.

The possibility of securing the chain saw directly to the harness reduces the risk of the machine being damaged if there is movement in the tree. The chain saw must always be switched oﬀ when it is attached directly to the harness.

If the chain saw is moved from any suspension ﬁ xture to another suspension ﬁ xture, the user must ensure that the saw is secured in the new position before it is released from the previous suspension ﬁ xture.

In order for the chain saw to be held in both hands, the user must assume a secure working position with the saw held at hip height when sawing horizontal pieces and at stomach height when sawing vertical pieces.

Using the chain saw in the tree

An analysis of accidents with these chain saws in tree care operations shows that the primary cause lies in the chain saw being used inexpertly in one hand. In the majority of accidents the users were not in a safe working position allowing them to hold the chain saw by both handles. This can lead to an increased risk of injury for the following reasons:

lack of grip when the chain saw kicks back,

•

lack of control over the chain saw, making

•

it more likely that it comes into contact with climbing ropes and the user’s body (particularly the left hand and the arm), and loss of control due to an unsafe working

•

position, causing contact with the chain saw (unexpected movements while working with the chain saw).

Safe working position with two-handed use

To enable the chain saw to be held in both hands, the user should always try to adopt a safe working position in which the saw is held in the following way:

at hip height, when sawing horizontal pieces,

•

and at stomach height, when sawing vertical

•

pieces.

If the user is working close to the trunk which runs vertically up the tree and the lateral force relative to the working position is low, secure footing is suﬃ cient for a safe working position. If the footing in the current position is not suﬃ cient, a stirrup formed from an endless sling must be used for added support (Fig 23).

However, as soon as the user moves away from the trunk, additional measures must be taken to reduce the increasing lateral forces or counteract them. This must be done by routing the main rope around an additional suspension ﬁ xture or by using an adjustable sling running from the harness to an additional suspension ﬁ xture (Fig.

24).

The chain brake must always be engaged before the chain saw is lowered on its suspension rope. Before starting diﬃ cult sawing work, the user must ensure that the chain saw battery is suﬃ ciently charged.

When doing tree care work, the user must never hold the saw in one hand while working in unstable positions or use the chain saw to cut oﬀ the tips of branches with small diameters instead of using a handsaw. Chain saws are allowed to be held in one hand for tree care work only if: a) it is not possible for the users to assume a

working position which allows them to hold the saw with two hands,

b) one hand is needed to secure the working

position, and

c) the chain saw is used in a fully outstretched

position at a right angle to and is not in line with the user’s body.

Users must never saw with the kickback area at the tip of the chain saw bar, hold on to the branch which they are cutting oﬀ or attempt to catch falling material.

If the chain saw jams during cutting, the user must: a) shut oﬀ the chain saw and attach it securely

towards the tree interior (e.g. towards the trunk) or secure it to a separate equipment rope,

b) remove the chain saw from the notch while

raising the branch up as much as necessary,

saw to release the chain saw which is stuck by making a cut which is at least 11.8" (30 cm) away from the chain saw which is stuck.

Regardless of whether a handsaw or chain saw is used to release a chain saw which has gotten stuck, the cuts made to release the chain saw must always be made towards the outside (towards the tips of the branches) so that the chain saw does not fall along with the pieces which have been cut oﬀ , complicating the situation.

Poor maintenance, use of non-approved spare parts, or the removal of safety equipment might result in serious injury. Incorrect, imprecise sharpening of the chain will result in increased danger due to recoiling and might result in serious injury. There is a risk of the chain jolting when cutting through the last ﬁ bers. Please keep a safe distance away in this area.

Pruning chain saw safety warnings:

1) Keep all parts of the body away from the pruner when the pruner is operating. Before you start the pruner, make sure the saw chain is not contacting anything.

A moment of inattention while operating pruners can cause entanglement of your clothing or body with the saw chain.

2) Always hold the pruner with your right hand on the rear handle and your left hand on the front handle. Holding the

pruner with a reversed hand conﬁ guration increases the risk of personal injury and should never be done.

3) Hold the power tool by insulated gripping surfaces only, because the saw chain could contact hidden wiring. Saw chains

contacting a ″live″ wire can make exposed metal parts of the power tool ″live″ and could give the operator an electric shock.

4) 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 ﬂ ying debris or accidental contact with the saw chain.

5) Do not operate a pruner in a tree.

Operation of a pruner while up in a tree can result in personal injury.

6) Always keep proper footing and operate the pruner only when standing on a ﬁ xed, secure, and level surface. Slippery or

unstable surfaces such as ladders can cause a loss of balance or control of the pruner.

7) When cutting a limb that is under tension, be alert for spring back. When the tension

in the wood ﬁ bres is released, the spring- loaded limb could strike the operator and/or throw the pruner out of control.

8) Use extreme caution when cutting brush and saplings. The slender material could

catch the pruner chain and be whipped toward you or pull you oﬀ balance.

9) Carry the pruner by the front handle with the pruner switched oﬀ and away from your body. When transporting or storing the pruner, always ﬁ t the guide bar cover.

Proper handling of the pruner will reduce the likelihood of accidental contact with the moving saw chain.

10) Follow instructions for lubricating, chain tensioning, and changing accessories.

Improperly tensioned or lubricated chain could break the pruner chain.

11) Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are

slippery, causing loss of control.

12) Cut wood only. Do not use pruner for purposes not intended. For example: do not use pruner for cutting plastic, masonry, or non-wood building materials.

Use of the pruner for operations diﬀ erent than intended could result in a hazardous situation.

13) Maintain a ﬁ rm grip, with thumbs and ﬁ ngers encircling the pruner handles,

with both hands on the pruner. Maintaining control of the pruner will reduce the risk of losing control. Do not let go of the pruner.

14) Do not overreach and do not cut above shoulder height. This enables better control

of the pruner in unexpected situations.

15) Only use replacement bars and chains speciﬁ ed by the manufacturer. Incorrect

replacement bars and chains can cause chain breakage and increase the risk of injury.

16) Follow the manufacturer’s sharpening and maintenance instructions for the pruner chain. Decreasing the depth gauge

height can lead to increased risk of injury.

General safety information for chain saws: a) Follow all instructions when clearing

jammed material, storing or servicing the chain saw. Make sure the switch is oﬀ and the battery pack is removed. Unexpected

actuation of the chain saw while clearing jammed material or servicing may result in

serious personal injury.

Residual risks

Even if you use this electric power tool in accordance to instructions, certain residual risks cannot be eliminated. The following hazards may arise in connection with the equipment’s construction and layout:

Cut injuries if no safety clothing is used.

•

Lung damage if no suitable protective dust

•

mask is applied. Damage to hearing if no suitable ear

•

protection is applied. Health damage caused by hand-arm

•

vibrations if the equipment is used over a longer period or is not properly guided and maintained.

Warning! The electric power tool generates an electromagnetic ﬁ eld during operation. Under certain circumstances this ﬁ eld may actively or passively impede medical implants. To reduce the risk of serious or fatal injuries, we recommend persons with medical implants to consult their doctor and the manufacturer of the medical implant prior to using the equipment.

If the equipment is used for a lengthy period, the vibrations it causes in the hands of the user might result in circulation problems (white ﬁ nger syndrome). White ﬁ nger syndrome is a vascular disease that involves seizure-like spasms of the ﬁ ngers and toes. The aﬀ ected areas are no longer suﬃ ciently supplied with blood and therefore appear extremely pale. The frequent use of vibrating equipment might trigger nerve damage in people with an impaired circulation (for example smokers, diabetics). Should you observe any unusual impairments, interrupt your work immediately and consult a doctor. Follow these instructions in order to reduce the dangers:

Keep your body and in particular your hands

•

warm when working in the cold. Take regular breaks and move your hands

•

to stimulate the blood circulation during the breaks. Ensure that the equipment makes the

•

least possible vibration through regular maintenance and solid parts on the equipment.

5. Before starting the equipment

Warning!

Always remove the battery before making adjustments to the equipment.

Danger! Do not ﬁ t the battery until the chain saw has been fully assembled and the chain tension has been set. Always wear protective gloves when working on the chain saw to protect yourself against injury.

5.1 Assembly of the bar and saw chain

Carefully unpack all parts and check that they

•

are complete (Fig. 2-3). Undo the chain tension lock knob (9) of the

•

chain wheel cover (Fig. 4). Take off the chain wheel cover (8) (Fig. 5).

•

Lay the chain (18) as shown in the groove

•

which runs around the bar (17) (Fig. 6/Item A). Insert the bar and chain as shown into the

•

mounting of the cordless chain saw. As you do so, guide the chain around the chain sprocket (Fig. 7 and 8/ Item B). Attach the chain wheel cover and secure

•

it with the chain tension lock knob (9) (Fig.

9). Important! Do not fully tighten the chain tension lock knob until after you have adjusted the chain tension (see section 5.2).

5.2 Tensioning the saw chain

Warning! Always disconnect battery before

performing any checks or adjustments. Always wear protective gloves when working on the chain saw to protect yourself against injury.

Undo the chain tension lock knob (9) of the

•

chain wheel cover a few turns (Fig. 4). Adjust the chain tension with the chain

•

tensioning knob (Fig. 10/ Item 10). Turning the knob clock-wise increases the tension, turning it counterclockwise decreases the chain tension. The saw chain is correctly tensioned if it can be lifted around 0.12"-0.16" (3-4 mm) in the middle of the bar (Fig. 10). Tighten the chain tension lock knob (9) of the

•

chain wheel cover (Fig. 9). Danger! All of the chain links must lie properly in the guide groove of the bar.

Notes on tensioning the chain:

The saw chain must be properly tensioned to ensure safe operation. You can tell that the chain tension is properly adjusted if the saw chain can be lifted by around 0.12"-0.16" (3-4 mm) in

the middle of the bar. As the saw chain heats up during cutting and thus changes in length, please check the chain tension every 10 minutes and adjust it again as required. This applies in particular to new saw chains. When you have ﬁ nished working loosen the chain again, as the chain will shorten when it cools down. This will prevent the chain from being damaged.

5.3 Saw chain lubrication Warning! Always disconnect the battery before

performing any checks or adjustments. Always wear protective gloves when working on the chain saw to protect yourself against injury.

Notice! Never operate the chain if it is not lubricated with saw chain oil. Use of the chain saw without saw chain oil or if the oil level is below the "min" mark (Fig. 12/ Item B) will damage the chain saw.

Notice! Be aware of the temperature conditions: diﬀ erent lubricants with completely diﬀ erent viscosities are required at diﬀ erent ambient temperatures. At lower temperatures you will need low viscosity oils in order to achieve a suﬃ cient lubricating ﬁ lm. However, if the same low viscosity oil is used during the summer it will become even thinner due to the ambient temperatures alone, and as a result the lubricating ﬁ lm could break down, causing the chain to overheat and become damaged. In addition, the chain oil would burn and produce unnecessary pollutants.

Filling the oil tank:

Keep away from ignition sources.

•

Place the chain saw on a flat surface.

•

Clean the area around the oil tank cap (Fig.

•

12/Item 7) and then clean the oil tank cap. Fill the tank with saw chain oil. In the process,

•

make sure that no dirt enters the tank, as this could cause the oil nozzle to become blocked. Close the oil tank cap.

•

6. Operation

6.1 Preparations

To ensure that you can work safely, check the following points before every use:

Condition of the chain saw

Inspect the chain saw before the start of work for damage to the housing, the saw chain and the bar. Never use a chain saw which is obviously damaged.

Oil tank

Fill level of the oil tank. Even while working, keep checking that suﬃ cient oil is in the system. To avoid damaging the chain saw, never run the saw if there is no oil in the system or if the oil drops below the "min" mark (Fig. 12/Item B). On average, a single ﬁ lling will last around 15 minutes depending on the number of pauses in cutting and the loads involved.

Saw chain

Tension of the saw chain, condition of the cutting elements. The sharper the chain saw, the easier and more controllable it is to operate the chain saw. The same also applies to the chain tension. Again, while working also check the chain tension every 10 minutes in order to increase your safety. New saw chains in particular often tend to expand more.

Chain brake

Check the operation of the chain brake as described in the chapter "Safety devices" and then release it.

6.2 Switching on/oﬀ

Switching on

Plug in the battery on the equipment.

•

Hold the chain saw by the handles with both

•

hands as shown in Fig. 15 (thumbs under the handles). Press and hold the safety lock-off (Fig. 1/

•

Item 5). To switch on the chain saw, press the On/Off

•

switch (Fig. 1/Item 6). You can then release the safety lock-off.

Switching oﬀ

Release the On/Oﬀ switch (Fig. 1/Item 6).

The integrated brake will bring the running chain saw to a standstill within a very short space of
