WARNING!
The vibration and noise emission level given in this information sheet has
been measured in accordance with a standardized test given in EN 62841 and may
be used to compare one tool with another. It may be used for a preliminary
assessment of exposure. The declared vibration and noise emission level
represents the main applications of the tool. However if the tool is used for
different applications, with different accessories or poorly maintained, the
vibration and noise emission may differ. This may significantly increase the
exposure level over the total working period. An estimation of the level of
exposure to vibration and noise should also take into account the times when
the tool is switched off or when it is running but not actually doing the job.
This may significantly reduce the exposure level over the total working
period. Identify additional safety measures to protect the operator from the
effects of vibration and/or noise such as: maintain the tool and the
accessories, keep the hands warm, organization of work patterns. Wear ear
protectors. Exposure to noise can cause hearing loss.
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.
GENERAL PRUNING SAW SAFETY WARNINGS
a) Keep all parts of the body away from the saw chain when the pruning saw is
operating. Before you start the pruning saw, make sure the saw chain is not
contacting anything. A moment of inattention while operating pruning saws may
cause entanglement of your clothing or body with the saw chain. b) Always hold
the pruning saw with your right hand on the rear handle and your left hand on
the front handle. Holding the pruning saw with a reversed hand configuration
increases the risk of personal injury and should never be done. c) Hold the
pruning 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 pruning saw live” and could give the operator an electric
shock. d) 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.
e) Do not operate a pruning saw in a tree, on a ladder, from a rooftop, or any
unstable support. Operation of a pruning saw in this manner could result in
serious personal injury. f) Always keep proper footing and operate the pruning
saw only when standing on fixed, secure and level surface. Slippery or
unstable surfaces may cause a loss of balance or control of the pruning saw.
g) 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 pruning saw out of control.
h) 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. i) Carry the pruning saw by the front handle with the pruning saw switched off and away from your body. When transporting or storing the pruning saw, always fit the guide bar cover. Proper handling of the pruning saw will reduce the likelihood of accidental contact with the moving saw chain. j) Follow instructions for lubricating, chain tensioning and changing the bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback. k) Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control. l) Cut wood only. Do not use pruning saw for purposes not intended. For example: do not use pruning saw for cutting metal, plastic, masonry or non-wood building materials. Use of the pruning saw for operations different than intended could result in a hazardous situation. Follow all instructions when clearing jammed material, storing or servicing the pruning saw. Make sure the switch is off and the battery pack is removed. Unexpected actuation of the pruning saw while clearing jammed material or servicing may result in serious personal injury. 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 saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw.

As a pruning saw user, you should take several steps to keep your cutting jobs
free from accident or injury. Kickback is the result of pruning saw misuse
and/or incorrect operating procedures or conditions and can be avoided by
taking proper precautions as given below:
a) Maintain a firm grip, with thumbs and fingers encircling the pruning 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 pruning saw.
b) Do not overreach and do not cut above shoulder height. This helps prevent
unintended tip contact and enables better control of the pruning saw in
unexpected situations. c) Only use replacement guide bars and chains specified
by the manufacturer. Incorrect replacement guide bars and chains may cause
chain breakage and/or kickback. d) Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain. Decreasing the depth gauge height
can lead to increased kickback.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
It is recommended to cut logs on a saw-horse or cradle when operating the
machine for the first time. Tethering Tethering with energy absorbing lanyards
only. Only attach the tether to lanyard loop. Do not attach the tether to
handle, guide bar cover, or any other point on the tool. Ensure all guards,
handles, and spiked bumper are properly fitted and are in good condition.
Persons using the pruning saw should be in good health. The pruning saw is
heavy, so the operator must be physically fit. The operator should be alert,
have a good vision, mobility, balance, and manual dexterity. If there is any
doubt, do not operate the pruning saw. Do not start using the pruning saw
until you have a clear work area, secure footing, and a planned retreat path
away from a falling tree. Beware of the emission of lubricant mist and saw
dust. Wear a mask or respirator, if required. Do not cut vines and/or small
undergrowth. Always hold the pruning saw with both hands during operation. Use
a firm grip with thumbs and fingers encircling the pruning saw handles. Right
hand must be on the rear handle and left hand on the front handle. Before
starting the pruning saw, make sure the saw chain is not contacting any
object. Do not modify the pruning saw in any way or use it to power any
attachments or devices not recommended by the manufacturer for your pruning
saw. There should be a first-aid kit containing large wound dressings and a
means to summon attention (e.g., whistle) close to the operator. A larger more
comprehensive kit should be reasonably nearby. An incorrectly tensioned chain
can jump off the guide bar and could result in serious injury or fatality. The
length of the chain depends on the temperature. Check the tension frequently.
You should get used to your new pruning saw by making simple cuts on securely
supported wood. Do this whenever you have not operated the saw for some time.
To reduce the risk of injury associated with contacting moving parts, always
stop the motor, remove the battery pack and make sure all moving parts have
come to a stop before: · cleaning or clearing a blockage
· leaving the machine unattended · installing or removing attachments ·
checking, conducting maintenance or working on the machine
The size of the work area depends on the job being performed as well as the
size of the tree or work piece involved. For example, felling a tree requires
a larger work area than making other cuts, i.e., bucking cuts, etc. The
operator needs to be aware and in control of everything happening in the work
area. Do not cut with your body in line with the guide bar and chain. If you
experience kickback, this will help prevent the chain coming into contact with
your head or body. Do not use a back-and-forward sawing motion, let the chain
do the work. Keep the chain sharp and do not try to push the chain through the
cut. Do not put pressure on the saw at the end of the cut. Be ready to take on
the weight of the saw as it cuts free from the wood. Failure to do so could
result in possible serious personal injury. Do not stop the saw in the middle
of a cutting operation. Keep the saw running until it is already removed from
the cut. Do not fix the on/off switch in the on position when using the saw
hand-held. Remove the battery pack before starting any work on the appliance.
WARNING! To reduce the risk of fire, personal injury, and
product damage due to a short circuit, never immerse your tool, battery pack
or charger in fluid or allow a fluid to flow inside them. Corrosive or
conductive fluids, such as seawater, certain industrial chemicals, and bleach
or bleach containing products, etc., Can cause a short circuit. Use only
System M18 chargers for charging System M18 battery packs. Do not use battery
packs from other systems. Never break open battery packs and chargers and
store only in dry rooms. Keep dry at all times. Push and pull The reaction
force is always opposite to the direction the chain is moving. Thus, the
operator must be ready to control the tendency for the machine to pull away
(forward motion) when cutting on the bottom edge of the bar and the push
backwards (towards the operator) when cutting along the top edge. Saw jammed
in the cut Stop the pruning saw and make it safe. Do not try to force the
chain and bar out of the cut as this is likely to break the chain, which may
swing back and strike the operator. This situation normally occurs because the
wood is incorrectly supported which forces the cut to close under compression,
thereby pinching the blade. If adjusting the support does not release the bar
and chain, use wooden wedges or a lever to open the cut and release the saw.
Never try to start the pruning saw when the guide bar is already in a cut or
kerf. Skating / Bouncing When the pruning saw fails to dig in during a cut,
the guide bar can begin hopping or dangerously skidding along the surface of
the log or branch, possibly resulting in the loss of control of the pruning
saw. To prevent or reduce skating or bouncing, always use the saw with both
hands make sure the saw chain establishes a groove for cutting. Never cut
small, flexible branches or brushes with your pruning saw. Their size and
flexibility can easily cause the saw to bounce towards you or bind up with
enough force to cause a kickback. The best tool for that kind of work is a
hand saw, pruning shears, an axe or other hand tools.
Personal protective equipment Wear a helmet at all times when operating the machine. A helmet, equipped with mesh visor, can help reduce the risk of injury to the face and the head if kickback occurs. Wear ear protectors! Good quality personal protective equipment, as used by professionals, will help reduce the risk of injury to the operator. The following items should be used when operating the machine:
Safety helmet should comply with EN 397 and be CE marked Hearing protection
should comply with EN 352-1 and be CE marked Eye and face protection
should be CE marked and comply with EN 166 (for safety glasses) or EN 1731
(for mesh visors) Gloves should comply with EN381-7 and be CE marked Leg
protection (chaps) should comply with EN 381-5, be CE marked and provide
allround protectionshould comply with EN 381-5, be CE marked and provide
allround protection Pruning saw safety boots
should comply with EN ISO 20345:2004 and be marked with a shield depicting a
pruning saw to show compliance with EN 381-3. (Occasional users may use steel
toe-cap safety boots with protective gaiters which conform to EN 381-9 if the
ground is even and there is little risk of tripping or catching on
undergrowth) Pruning saw jackets for upper body protection
should comply with EN 381-11 and be CE marked

WARNING!
Consequences of improper maintenance, removal or modification of safety
features, ignition switch, hand guard (front and back), spiked bumper, chain
catcher, guide bar, low kick-back saw chain may cause the safety features to
not function correctly, thus increasing the potential for serious injury.
Spiked Bumper The integral bumper spike may be used as a pivot when making a
cut. It helps to keep the body of the pruning saw steady while cutting. When
cutting, push the machine forward until the spikes dig into the edge of the
wood, then by moving the rear handle up or down in the direction of the
cutting line it can help ease the physical strain of cutting. Guide Bar
Generally, guide bars with small radius tips have somewhat lower potential for
kick-back. You should use a guide bar and matching chain which is just long
enough for the job. Longer bars increase the risk of loss of control during
sawing. Regularly check the chain tension. When cutting smaller branches (less
than the full length of the guide bar) the chain is more likely to be thrown
off if the tension is not correct.
INSTRUCTIONS CONCERNING THE PROPER TECHNIQUES FOR BASIC FELLING, LIMBING AND
CROSS-CUTTING Understanding the forces within the wood When you understand the
directional pressures and stresses inside the wood you can reduce the
“pinches” or at least expect them during your cutting. Tension in the wood
means the fibers are being pulled apart and if you cut in this area, the
“kerf” or cut will tend to open as the saw goes through. If a log is being
supported on a saw horse and the end is hanging unsupported over the end,
tension is created on the upper surface due to the weight of the overhanging
log stretching the fibers. Likewise, the underside of the log will be in
compression and the fibers are being pushed together. If a cut is made in this
area, the kerf will have the tendency to close up during the cut. This would
pinch the blade. Limbing a tree Limbing is removing the branches from a fallen
tree. When limbing, 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 up to avoid binding the pruning saw. Cutting springpoles A
springpole is any log, branch, rooted stump, or sapling which is bent under
tension by other wood so that it springs back if the wood holding it is cut or
removed. On a fallen tree, a rooted stump has a high potential of springing
back to the upright position during the bucking cut to separate the log from
the stump. Watch out for springpoles, they are dangerous.
WARNING! Springpoles are dangerous and could strike
the operator, causing the operator to lose control of the pruning saw. This
could result in severe or fatal injury to the operator. This should be done by
trained users.
SPECIFIED CONDITIONS OF USE
The cordless pruning saw is only intended for use outdoors. For safety
reasons, the pruning saw must be adequately controlled by using two-handed
operation at all times. The pruning saw is designed for cutting branches,
trunks, logs, and beams of a diameter determined by the cutting length of the
guide bar. It is only designed to cut wood. It is only to be used by adults
who have received adequate training on the hazards and preventative
measures/actions to be taken while using the pruning saw. Do not use the
pruning saw for any purpose not listed in the specified conditions of use. It

WARNING! When using the pruning saw, the safety rules
must be followed. For your own safety and that of bystanders, you must read
and fully understand these instructions before operating the pruning saw. You
should attend a professionally organized safety course in the use,
preventative actions, first-aid, and maintenance of pruning saws. Please keep
these instructions safe for later use.
WARNING! Pruning saws are potentially dangerous
tools. Accidents involving the use of pruning saws often result in loss of
limbs or death. It is not just the pruning saw that is the hazard. Falling
branches, toppling trees, and rolling logs can all kill. Diseased or rotting
timber poses additional hazards. You should assess your capability of
completing the task safely. If there is any doubt, leave it to a professional
tree surgeon. Do not use this product in any other way as stated for normal
use.
RESIDUAL RISK
Even when the product is used as prescribed, it is still impossible to
completely eliminate certain residual risk factors. The following hazards may
arise in use and the operator should pay special attention to avoid the
following: · IInjury caused by vibration
Always use the right tool for the job. Use designated handles. Restrict
working time and exposure. · Damage to hearing due to exposure to noise Wear
hearing protection and limit exposure. · Injury caused by contact with exposed
saw teeth of the chain · Injury caused by thrown-out pieces of the workpiece
(wood chips, splinters) · Injury caused by dust and particles · Injury to the
skin caused by contact with lubricants · Parts ejected from the saw chain
(cutting/injection hazards) · Unforeseen, abrupt movement, or kickback of the
guide bar (cutting hazards)
RISK REDUCTION
· It has been reported that vibrations from handheld tools may contribute to a
condition called Raynaud’s Syndrome in certain individuals. Symptoms may
include tingling, numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to cold and dampness,
diet, smoking and work practices are all thought to contribute to the
development of these symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
· Keep your body warm in cold weather. When operating the unit wear gloves to
keep the hands and wrists warm.
· After each period of operation, exercise to increase blood circulation.
· Take frequent work breaks. Limit the amount of exposure per day. ·
Protective gloves available from professional pruning saw
retailers are designed specifically for pruning saw use which give protection,
good grip and also reduce the effect of handle vibration. These gloves should
comply with EN 381-7 and must be CE marked. If you experience any of the
symptoms of this condition, immediately discontinue use and see your doctor. –
WARNING! Injuries may be caused, or aggravated, by
prolonged use of a tool. When using any tool for prolonged periods, ensure you
take regular breaks.
NOTES FOR LI-ION BATTERIES Use of Li-Ion batteries
Battery packs which have not been used for some time should be recharged
before use.
Temperatures in excess of 50°C (122°F) reduce the performance of the battery
pack. Avoid extended exposure to heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum life-time, the battery packs have to be fully charged, after
use.
To obtain the longest possible battery life remove the battery pack from the
charger once it is fully charged. For battery pack storage longer than 30
days: Store the battery pack where the temperature is below 27°C and away from
moisture Store the battery packs in a 30% – 50% charged condition Every six
months of storage, charge the pack as normal.
Battery protection for Li-Ion batteries In extremely high torque, binding,
stalling and short circuit situations that cause high current draw, the tool
will vibrate for about 5 seconds, the fuel gauge will flash,and then the tool
will turn OFF. To reset, release the trigger. Under extreme circumstances, the
internal temperature of the battery pack could raise too much. If this
happens, the fuel gauge will flash until the battery pack cooled down. After
the lights go off, the work may continue.
Transporting Lithium Batteries Lithium-ion batteries are subject to the
Dangerous Goods Legislation requirements. Transportation of those batteries
has to be done in accordance with local, national and international provisions
and regulations. The user can transport the batteries by road without further
requirements. Commercial transport of Lithium-Ion batteries by third parties
is subject to Dangerous Goods regulations. Transport preparation and transport
are exclusively to be carried out by appropriately trained persons and the
process has to be accompanied by corresponding experts. When transporting
batteries: Ensure that battery contact terminals are protected and insulated
to prevent short circuit. Ensure that battery pack is secured against movement
within packaging. Do not transport batteries that are cracked or leak.Check
with forwarding company for further advice.
WORKING INSTRUCTIONS ASSEMBLY Assembling saw chain and guide bar
WARNING! If any parts are damaged or missing do not
operate the machine until the parts are replaced. Failure to heed this warning
could result in serious personal injury. Make sure to remove the battery. Wear
gloves! 1. Remove the bar mounting nuts using the combination wrench
provided. 2. Remove the drive sprocket cover. 3. Put the chain in the correct
direction onto the bar and make sure
that the drive links are aligned in the bar groove. 4. Attach the bar to the
pruning saw and loop the chain around the
drive sprocket. 5. Replace the drive sprocket cover and bar mounting nuts. 6.
Finger-tighten the bar mounting nuts. The bar must be free to
move for chain tension adjustment. 7. Adjust the chain tension. Refer to the
“Adjusting chain tension”
section. 8. Hold the tip of the guide bar up and tighten the bar mounting nuts
securely.
WARNING! The saw chain is sharp. Always wear
protective gloves when performing maintenance to the chain. Adjusting the
chain tension Remove the battery pack before you do any work on the pruning
saw. To increase the chain tension, turn the chain tensioning screw clockwise
and check the chain tension frequently. To reduce the chain tension, turn the
chain tensioning screw counterclockwise and check the chain tension
frequently.

ENGLISH
The chain tension is correct when the gap between the cutter in the chain and
the bar is about 6,8 mm. Pull the chain in the middle of the lower side of the
bar downwards (away from the bar) and measure the distance between the bar and
the chain cutters. Tighten the bar mounting nuts by turning it counter
clockwise. Note: Do not over-tension the chain – excess tension will cause
excessive wear and will reduce the life of the chain and could damage the bar.
New chains could stretch and loosen during initial use. Remove battery pack
and check chain tension frequently during the first two hours of use. The
temperature of the chain increases during normal operation causing the chain
to stretch. Check the chain tension frequently and adjust as required. A chain
tensioned while warm may be too tight upon cooling. Make sure that the chain
tension is correctly adjusted as specified in these instructions. Adding the
chain lubricating oil
WARNING! Never work without chain lubricant. If the saw
chain is running without lubricant, the guide bar and the saw chain can be
damaged. It is essential to frequently check the oil level in the oil level
gauge and before starting to use the pruning saw.Keep the reservoir more than
¼ full to ensure sufficient oil is available for the job. Note: It is
recommended to use a vegetable based chain oil when pruning trees. Mineral oil
may harm trees. Never use waste oil automotive oil, or very thick oils. These
could damage the pruning saw. Clear surface around the oil cap to prevent
contamination. 1. Unscrew and remove the cap from the oil tank. 2. Pour the
oil into the oil tank and monitor the oil level gauge. 3. Put the oil cap back
on and tighten it up. Wipe away any
spillage. Holding the pruning saw Always hold the pruning saw with your right
hand on the rear handle and your left hand on the front handle. Grip both
handles with the thumbs and fingers encircling the handles. Starting the
pruning saw Before starting the pruning saw, you should install the battery
pack in the pruning saw. Restart protection The power tool is supplied with a
restart protection. This prevents the switched-on power tool from starting by
itself when the battery pack is inserted and from restarting after a switch-
off function of the battery pack. If the guide bar is outside of the wood
switch off the machine and switch it back on again in order to continue to
work. If the guide bar is inside of the wood wait until the saw chain comes to
a complete stop. Make sure that the switch is in the off position. Remove the
battery pack from the machine and the guide bar from the cut. Insert the
battery pack and then switch the machine back on again, in order to continue
to work.
TRANSPORTATION AND STORAGE
Always lightly oil the chain when storing to prevent rust. Always empty the
oil tank when storing to prevent leakage. Stop the machine, remove the
battery, and allow it to cool before storing or transporting. Clean all
foreign materials from the machine. Store the machine in a cool, dry, and
well-ventilated place that is inaccessible to children. Keep away from
corrosive agents, such as garden chemicals and de-icing salts. Do not store
outdoors. Fit the guide bar cover before storing the machine or during
transportation. For transportation in vehicles, secure the machine against
movement or falling to prevent injury to persons or damage to the machine.
CLEANING
Clean dust and debris from openings. Keep handle clean, dry and free of oil or
grease. Use only mild soap and a damp cloth to clean, since certain cleaning
agents and solvents are harmful to plastics and other insulated parts. Some of
these include gasoline, turpentine, lacquer thinner, paint thinner,
chlorinated cleaning
solvents, ammonia and household detergents containing ammonia. Never use
flammable or combustible solvents around tools.
MAINTENANCE
