General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in
electric shock, re and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
1) 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 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. Unmodi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 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 in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 o-position before connecting to power source and/
or battery pack, picking up or carrying the tool. Carrying
power tools with your nger 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 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 o. 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 a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, taking into account
the working conditions and the work to be performed.
Use of the power tool for operations dierent 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.
5) Battery tool use and care
a) Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of re when used with another
battery pack.
b) Use power tools only with specically designated
battery packs. Use of any other battery packs may create a
risk of injury and 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 re.
d) Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally occurs,

546875 - Masport Aerocore Chainsaw Owner’s Manual - December 2020
4
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 modied. Damaged or modied batteries may exhibit
unpredictable behaviour resulting in re, explosion or risk of
injury.
f) Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or temperature
above 130 °C may cause explosion.
g) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature range
specied in the instructions. Charging improperly or at
temperatures outside the specied range may damage the
battery and increase the risk of re.
6) Service
a) Have your power tool serviced by a quali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.
Safety warning for Battery Pack
a) Do not dismantle, open or shred cells or battery pack.
b) Do not short-circuit a battery pack. Do not store
battery packs haphazardly in a box or drawer where they
may short-circuit each other or be short-circuited by
conductive materials. 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 re.
c) Do not expose battery pack to heat or re. Avoid
storage in direct sunlight.
d) Do not subject battery pack to mechanical shock.
e) In the event of battery leaking, do not allow the liquid
to come into contact with the skin or eyes. If contact
has been made, wash the aected area with copious
amounts of water and seek medical advice.
f) Seek medical advice immediately if a cell or battery
pack has been swallowed.
g) Keep battery pack clean and dry.
h) Wipe the battery pack terminals with a clean dry cloth
if they become dirty.
i) Battery pack needs to be charged before use. Always
refer to this instruction and use the correct charging
procedure.
j) Do not maintain battery pack on charge when not in
use.
k) After extended periods of storage, it may be
necessary to charge and discharge the battery pack
several times to obtain maximum performance.
l) Battery pack gives its best performance when it is
operated at normal room temperature (20 °C ± 5 °C).
m) When disposing of battery packs, keep battery packs
of dierent electrochemical systems separate from each
other.
n) Recharge only with the charger specied by Masport.
Do not use any charger other than that specically
provided for use with the equipment. A charger that is
suitable for one type of battery pack may create a risk of re
when used with another battery pack.
o) Do not use any battery pack which is not designed for

WARNING! To reduce the risk of injury, user must
read and understand instruction manual.
1) General chain saw safety warnings:
a) 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.
b) Always hold the chain saw with your right hand on
the rear handle and your left hand on the front handle.
Holding the chain saw with a reversed hand conguration
increases the risk of personal injury and should never be
done.
c) 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.
d) Wear safety glasses protection. Further protective
equipment for hearing, head, hands, legs and feet is
recommended. Adequate protective clothing will reduce
personal injury by ying debris or accidental contact with the
saw chain.
e) Do not operate a chain saw in a tree, on a ladder, from
a rooftop, or any unstable support. Operation of a chain
saw in this manner could result in serious personal injury.
f) Always keep proper footing and operate the chain saw
only when standing on xed, secure and level surface.
Slippery or unstable surfaces may cause a loss of balance or
control of the chain saw.
g) When cutting a limb that is under tension , be alert for
spring back. When the tension in the wood bres is released
, the spring loaded limb may strike the operator and/or throw
the chain 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 o balance.
i) Carry the chain saw by the front handle with the chain
saw switched o and away from your body. When
transporting or storing the chain saw , always t the
guide bar cover. Proper handling of the chain 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) Cut wood only. Do not use chain saw for purposes not
intended. For example: do not use chain saw for cutting
metal, plastic, masonry or non-wood building materials.
Use of the chain saw for operations dierent than intended
could result in a hazardous situation.
l) Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid them.
Serious injury could occur to the operator or bystanders
while felling a tree.
m) Follow all instructions when clearing jammed
material, storing or servicing the chain saw. Make
sure the switch is o and the battery pack is removed.
Unexpected actuation of the chain saw while clearing
jammed material or servicing may result in serious personal
injury.
n) Recommendation that the rst-time user should, as a
minimum, practise cutting logs on a saw-horse or cradle.
o) Recommendation to have sharpening and
maintenance of the saw chain performed by authorised
service centres.
2) 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 chain saw user, you should
take several steps to keep your cutting jobs free from
accident or injury.
Kickback is the result of chain saw misuse and/or incorrect
operating procedures or conditions and can be
avoided by taking proper precautions as given below:
a) Maintain a rm grip, with thumbs and ngers
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.
b) 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
situations.
c) Only use replacement bars and chains specied by
the manufacturer. Incorrect replacement guide bars and
saw 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.

3) Instructions concerning the proper techniques for
basic felling, limbing, and cross-cutting
3.1 Felling a tree
When bucking and felling operations are being performed by
two or more persons at the same time, the felling operations
should be separated from the bucking operation by a
distance of at least twice the height of the tree being felled.
Trees should not be felled in a manner that would endanger
any person, strike any utility line or cause any property
damage. If the tree does make contact with any utility line,
the company should be notied immediately.
The chain saw operator should keep on the uphill side of the
terrain as the tree is likely to roll or slide downhill after it is
felled.
An escape path should be planned and cleared as necessary
before cuts are started. The escape path should extend
back and diagonally to the rear of the expected line of fall as
illustrated in Figure 1.
Before felling is started, consider the natural lean of the tree,
the location of larger branches and the wind direction to
judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples and wire from
the tree.
3.2 Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular
to the direction of falls as illustrated in Figure 1. Make the
lower horizontal notching cut (W) rst. This will help to avoid
pinching either the saw chain or the guide bar when the
second notch (X) is being made.
3.3 Felling back cut
Make the felling back cut (Y) at least 50 mm higher than the
horizontal notching cut as illustrated in Figure 1. Keep the
felling back cut parallel to the horizontal notching cut. Make
the felling back cut so enough wood is left to act as a hinge.
The hinge wood keeps the tree from twisting and falling in
the wrong direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree should begin
to fall. If there is any chance that the tree may not fall in
desired direction or it may rock back and bind the saw chain,
stop cutting before the felling back cut is complete and use
wedges of wood, plastic or aluminium (Z) to open the cut
and drop the tree along the desired line of fall (3).
When the tree begins to fall remove the chain saw from the
cut, stop the motor, put the chain saw down, then use the
retreat path planned (2). Be alert for overhead limbs falling
and watch your footing.
Figure 1
3.4 Limbing a tree
Limbing is removing the branches from a fallen tree. When
limbing leave larger lower limbs to support the log o the
ground. Remove the small limbs in one cut as illustrated in
Figure 2. Branches under tension should be cut from the
bottom up to avoid binding the chain saw.
Figure 2
3.5 Bucking a log
Bucking is cutting a log into lengths. It is important to make
sure your footing is rm and your weight is evenly distributed
on both feet. When possible, the log should be raised and
supported by the use of limbs, logs or chocks. Follow the
simple directions for easy cutting.
When the log is supported along its entire length as
illustrated in Figure 3, it is cut from the top (overbuck), avoid
contacting ground as this will greatly reduce the chain
sharpness.
Figure 3
When the log is supported on one end, as illustrated in Figure
4, cut 1/3 the diameter from the underside ( underbuck) (1).
Then make the nished cut by overbucking (2) to meet the
rst cut.
Figure 4
When the log is supported on both ends, as illustrated in
Figure 5, cut 1/3 the diameter from the top (overbuck) (1).
Then make the nished cut by underbucking (2) the lower
2/3 to meet the rst cut.

Figure 5
When bucking on a slope always stand on the uphill side of
the log, as illustrated in Figure 6. When “cutting through”, to
maintain complete control release the cutting pressure near
the end of the cut without relaxing your grip on the chain
saw handles. Don’t let the chain contact the ground. After
completing the cut, wait for the saw chain to stop before you
move the chain saw. Always stop the motor before moving
from tree to tree.

Warning: Do not install the battery pack before it
has been completely assembled. Always use gloves
when handling the chain.
5. Fit the chain onto the drive sprocket. Ensure the bar
tensioning plate is facing outward. (see Fig. A4, A5.)
6. Ensure all parts are seated properly. Make sure the drive
links are fully seated in the drive sprocket (see Fig. A6.), avoid
placing the chain in the inverse direction 9 (see Fig. A7.) If
kink occurs, pick up on the chain at the guide bar just ahead
of the kink and then pull the kink out.
NOTE: Chain should rotate freely and be free of kinks.
7. Tension the chain by tightening the chain tensioning screw
(15) in clockwise direction using the supplied screwdriver.
(see Fig. A8.) Do not overtighten.
8. Press the chain cover onto the bar pad; screw the 2 nuts
onto the guide pins for chain bar to lock the chain cover. (see
Fig. A9.)
9. If the chain is still loose, tension the chain by tightening the
chain tensioning screw (15) using the supplied screwdriver
(19). (see Fig. A10.)
TENSIONING CHAIN AND BAR
NOTE: New saw chains will stretch. Check the chain
tension frequently during rst use, and tighten when the
chain becomes loose around the guide bar.
WARNING!
•Remove the battery pack before adjusting saw chain
tension.
•Cutting edges on chain are sharp. Use protective gloves
when handling chain.
•Maintain proper chain tension always. A loose chain will
increase the risk of kickback. A loose chain may jump
out of guide bar groove. This may injure operator and
damage chain. A loose chain will cause chain, bar, and
sprocket to wear rapidly.
LUBRICATION
NOTE: Chain life and cutting capacity depend on
optimum lubrication. Therefore, the chain is automatically
oiled during operation.
1. Set chainsaw on any suitable surface with oil ller cap
facing upward.
2. Clean area around the oil ller cap with a cloth, and
unscrew the cap by turning it counter-clockwise.
3. Add chain oil until tank is full.
4. Avoid dirt or debris entering oil tank. Ret oil ller cap and
tighten by turning clockwise until hand tight.
It is important to use only the recommended bar and
chain oil to avoid damage to the chainsaw. Never use
recycled/old oil. Use of non-approved oil will void the
warranty. Do not swallow. If swallowed, call a physician
immediately. Keep out of reach of children. Store away
from heat or open ame.
Checking the Automatic Oiler
Proper functioning of the automatic oiler can be checked by
running the chainsaw and pointing the tip of the chain guide
bar towards a piece of cardboard or paper on the ground.
If an increasing oil pattern develops on the cardboard, the
automatic oiler is operating ne. If there is no oil pattern,
despite a full oil reservoir, contact the customer service agent
or a CTC-approved service agent.

WARNING!
• The chainsaw is not lled with oil. It is essential to ll
with oil before use. Never operate the chainsaw without
chain oil or at an empty oil tank level, as this will result in
extensive damage to the product.
• Remove the battery pack before lling the oil tank.
•To allow proper ventilation of the oil tank, small breather
channels are provided between the oil ller cap and the
strainer to prevent leakage. Ensure machine is left in a
horizontal position when not in use.
•Do not touch the ground with the chain. Ensure safety

WARNING! The battery pack will be too cold to be
used if it has been left in the environment with too low
temperature (less than -20 degrees Celsius) for a long
time. The battery pack needs to be warmed up before
use.
How to use Saw Safely
3.1. Use the chainsaw only with secure footing.
3.2. Hold the chainsaw at the right-hand side of your body.
(see Fig. E.)
3.3. The chain must be running at full speed before it makes
contact with the wood.
3.4. Do not operate the chainsaw with arms fully extended,
attempt to saw areas which are dicult to reach, or stand on
a ladder while sawing. (see Fig. F.)
Never use the chainsaw above shoulder height.
4. THE CHAIN BRAKE (See Fig. G)
The chain brake lever is a safety mechanism activated
through the front hand guard when kickback occurs. The
chain stops immediately.
The following function check should be carried out at regular
intervals.
4.1. Manual chain brake: push front hand guard forward
(position 2) and try starting the chainsaw. The chainsaw
must not start. To deactivate the kickback brake, pull hand
guard backwards (position 1), and release on/o switch. (See
component list for switch on and o locations.)
4.2. Automatic chain brake: release the on/o switch to
activate chain brake automatically.
5. CUTTING
5.1 Install the battery pack into the machine.
5.2 Make sure section of log to be cut is not laying on the
ground. This will keep the chain from touching the ground as
it cuts through the log. Touching the ground while the chain
is moving is dangerous and will dull the chain.
5.3 Use both hands to grip saw. Always use left hand to grip
front handle and right hand to grip rear handle. Use a rm
grip. Thumbs and ngers must wrap around saw handles.
(See Fig. H.)
5.4 Make sure your footing is rm. Keep feet shoulder-width
apart. Distribute your weight evenly on both feet.
5.5 When ready to make a cut, push the lock-out button
completely in with the right thumb and squeeze the trigger.
This will turn saw on. Releasing the trigger will turn the saw
o. Make sure the saw is running at full speed before starting
a cut.
5.6 When starting a cut, slowly place moving chain against
the wood. The wood should be as close to the saw body as
possible. Hold saw rmly in place to avoid possible bouncing
or skating (sideways movement) of saw.
5.7 Guide the saw using light pressure and do not put
excessive force on the saw, letting the saw do its work.
Excessive force can cause the motor to overload and burn
out. It will do the job better and safer at the rate for which it
was intended.
5.8 Remove the saw from a cut with the saw running at full
speed. Stop the saw by releasing the on/o switch. Make
sure the chain has stopped before setting the saw down.
5.9 Keep practicing on scrap logs in a secure working area
until you are comfortable, using a uid motion and a steady
cutting rate.
Kickback Safety Devices On This Saw
This saw has a low-kickback chain and reduced kickback
guide bar. Both items reduce the chance of kickback.
However, kickback can still occur with this saw.
The following steps will reduce the risk of kickback.

546875 - Masport Aerocore Chainsaw Owner’s Manual - December 2020
11
• Use both hands to grip saw while saw is running. Use
a rm grip. Thumbs and ngers must wrap around saw
handles.
• Keep all safety items in place on saw. Make sure they work
properly.
• Do not overreach or cut above shoulder height.
• Keep solid footing and balance at all times.
• Stand slightly to the left side of saw. This keeps your body
from being in direct line with chain.
• Do not let the guide bar nose touch anything when chain is
moving.
• Never try cutting through two logs at same time. Only cut
one log at a time.
• Do not bury the guide bar nose or try plunge cut (boring
into wood using guide bar nose).
• Watch for shifting of wood or other forces that may pinch
chain.
• Use extreme caution when reentering a previous cut.
• Use only the low-kickback chain and guide bar that were
supplied with this chainsaw or recommended.
• Never use a dull or loose chain. Keep chain sharp with
proper tension.
Maintenance
Saw Maintenance
Follow maintenance instructions in this manual. Proper
cleaning of saw and chain and guide bar maintenance can
reduce chances of kickback. Inspect and maintain saw after
each use. This will increase the service life of your saw.
Note: Even with proper sharpening, risk of kickback can
increase with each sharpening.
Bar Maintenance
To maximize bar life, the following bar maintenance is
recommended.
The bar rails that carry the chain should be cleaned before
storing the tool or if the bar or chain appear to be dirty.
The rails should be cleaned every time the chain is removed.
To Clean the Bar Rails
1. Remove chain cover and bar and chain. (See section
ASSEMBLY.)
2. Using a wire brush, screwdriver or similar tool, clear the
residue from the inner groove of the bar. (see Fig. I.)
3. Make sure to clean oil passages thoroughly
Conditions which require chain and guide bar maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• Inadequate supply of oil to the bar and chain.
Check the condition of the guide bar each time the chain
is sharpened. A worn guide bar will damage the chain and
make cutting dicult.
After each use, remove the battery pack, and clean all
sawdust from the guide bar and sprocket hole.
When rail top is uneven, use a at le to restore square
edges and sides.
Replace the guide bar when the groove is worn, the guide
bar is bent or cracked, or when excessive heating or burring
of the rails occurs. If replacement is necessary, use only the
guide bar specied for your saw in the repair parts list or on
the decal located on the chainsaw.
Replacing Bar and Chain
Replace chain when cutters are too worn to sharpen or
when chain stops. Only use replacement chain noted in this
manual.
Inspect guide bar before sharpening chain. A worn or
damaged guide bar is unsafe. A worn or damaged guide bar
will damage chain. It will also make cutting harder.
Sharpening the Saw Chain
Cutting edges on chain are sharp. Use protective gloves
when handling chain.
Keep chain sharp. Your saw will cut faster and more safely.
A dull chain will cause undue sprocket, guide bar, chain, and
motor wear. If you must force chain into wood, and cutting
creates only sawdust with few large chips, the chain is dull.
NOTE:
It is not necessary to remove the chain or bar when
lubricating the guide bar sprocket.
1. Clean the bar and sprocket.
2. Using a grease gun, insert the tip of the gun into the
lubrication hole and inject grease until it appears at the
outside edge of the sprocket tip. (see Fig. J.)
3. To rotate the sprocket, pull the chain by hand until the
ungreased side of the sprocket is in line with the grease hole.
Repeat the lubrication procedure.
