Installation and regulation of tool elements
Switch off the tool before fullling all procedures.
Do not draw up the fastening elements
too tight to avoid damaging the thread.
Mounting / dismounting / setting-up of
some elements is the same for all tool
models, in this case specic models are
not indicated in the illustration.
Assembly / disassembly of the spiked bumper kit
(see g. 1)
•Put the tool on at ground.
•Install spiked bumper kit 3and screw the screw 28
with the help of the special wrench 26 (see g. 1).
•When disassembling the spiked bumper kit 3, repeat
the above operations in reverse order�
Assembly / disassembly of the cutting unit,
tensioning of the saw chain (see g. 2-4)
When used for extended periods of time,
guide bar 1 and saw chain 2 can become
very hot, therefore, you must wear pro-
tective gloves during assembly opera-
tions. This will also reduce the risk of injury from
the cutting edge of saw chain.
•Put the tool on at ground.
•Unscrew the nuts 29 with the help of the multi-
purpose wrench 25 (see g. 2.1).
•Move brake guard 4into the rearmost position and
remove guide bar cover 31 (see g. 2.1-2.2).
•Install guide bar 1 (see g. 3) and move it into
the direction of drive gear 32 (this will facilitate the
installation of saw chain 2)�
•Wrap saw chain 2around drive gear 32, then, place
the drive teeth of saw chain 2into the slot of the guide
bar 1� Note: saw chain 2 is installed correctly when
the cutting edges are facing forward.
•Install guide bar cover 31 (the tension pin must fall
into the hole in guide bar 1)�
•Screw nuts 29 onto pins 30 and tighten them slightly
by hand�
•Adjust the tension of saw chain 2� Holding the
front of guide bar 1 (see g. 4.1), rotate chain tension
screw 33 with a screwdriver (see g. 4.2). To increase
the tension of saw chain 2, turn chain tension screw 33
to the right, turn it left to reduce the tension�
•Pull saw chain 2until it abuts closely to the bottom
of guide bar 1�
•Continue to hold the front of guide bar 1while
tightening nuts 29 with multi-purpose wrench 25�
•When disassembling the cutting unit, repeat the
above operations in reverse order�
Saw chain tension checking (see g. 5)
Prior to each use of the tool and by
operation it is necessary to perform a
check, and if necessary, to adjust the
tension of the saw chain 2.
When operating saw chain 2, consider the following
factors:

17
English
•saw chain 2must always be properly tensioned,
and its lubrication system must function properly;
•new saw chain 2stretches more, inspection and
tension adjusting operations must be carried out
more frequently;
•during operation, saw chain 2gets heated and
lengthens, it shortens during cooling, consider this
factor when adjusting the chain tension: do not
adjust saw chain 2when it is hot�
The following are the indicators of a correctly tensioned
saw chain:
•pull saw chain 2from the center of guide bar 1
lightly and release. If saw chain 2is tensioned
correctly, the maximum distance between the pulled
saw chain 2and guide bar 1 is 3-4 mm (see g. 5.1);
•a properly tensioned saw chain 2should not sag
(see g. 5.2);
•a properly tensioned saw chain 2must move
freely around guide bar 1when pulled by hand (use
protective gloves when doing this, see g. 5.3). If
it does not, loosen the tension of saw chain 2, as
described above�
Saw chain lubrication system functioning check
(see g. 6)
The operation of the lubrication system of saw chain 2
can be checked as follows:
•run the tool engine and keep the end of the cutting
unit above a piece of cardboard or paper laid on the
ground;
•Note: Do not touch the ground with the chain,
maintain a distance of about 200 mm. If the above
results in the appearance of increasing traces of oil
on cardboard or paper, the chain lubrication system is
working properly. If, despite the oil tank being full, no
oil traces appear, contact the CROWN service center�
The amount of oil that lubricates saw chain 2can
be adjusted with the help of screw 34 (see g. 6). To
increase the volume of oil ow to the chain, rotate
adjusting screw 34 to the left, rotate it to the right to
reduce the oil ow.
The saw chain brake functioning check (see g. 7)
The saw chain brake must be activated at the recoil
of the tool. To check the functionality of the saw chain
brake, perform the following steps.
•Run the tool engine (as described below), place
it on the ground so that saw chain 2is out of contact
with the ground or with any other objects� Hold both
handles of the tool, start with full power (saw chain 2
begins moving). Press brake guard 4with your left hand
to move it forward (see g. 7) - saw chain 2must stop
immediately�
•If the saw chain brake does not function as described
above, contact the CROWN service center�
Do not operate the tool if the saw chain
brake is damaged.
Always keep in mind that even a
properly operating chain brake
may not provide protection in some
cases (for example, if the operator
falls or in the event of tree felling, when the cutting
unit plane is parallel to the ground etc.).
Initial operating of the tool
Mandatory check
Prior to commencing the work, be sure to check the
following:
•correctness of mounting and reliability of xing of all
elements of the tool;
•absence of damages to the elements of the tool;
•absence of fuel leaks;
•saw chain tension;
•correct operation of the saw chain lubrication
system;
•correct operation of the saw chain brake.
Information on the fuel mixture and oil to lubricate
the saw chain
Fuel for the two-stroke engine of the tool
is a mixture of petrol (octane number
of not less than 89RON) with special
motor oil in a proportion specied in the
engineering data sheet.
•Do not use other kind of oil (for example, motor oil
for four-stroke engines or oil for two-stroke engines of
motor boats)�
•Always precisely measure out the volume of the fuel
mixture's components - even a small inaccuracy may
lead to incorrect operation of the engine�
•It is expressly prohibited to use other fuel
mixtures as well as petrol alone for fueling of the
tool�
•Do not use the fuel mixture that has been stored for
more than a month�
Use only special oil to lubricate the saw
chain.
•Do not use other sorts of oil (e�g�, engine oil for four-
stroke engines etc.).
•Don not use waste oil under any circumstances�
•Note that , some sorts of oil thicken at a temperature
of 0°C and below, which may result in the incorrect
operation of the saw chain lubrication system or
damage to the tool� Follow the recommendations on
the oil used to lubricate the saw chain�
Non-observance of these rules may lead
to breaking of the engine and deprive
you of the right to warranty repair.

•Place the tool on the ground, step on the lower
part of handle 8and hold front handle 5with your left
hand (see g. 11.1). Note: Never force the tool to
the ground by pressing other design elements with
your foot. Pull the starter cord handle 7lightly a few
times until you feel resistance�
•Pull at the starter cord 7several times until initial
ignitions are heard�
•Move air throttle control lever 13 into its most forward
position (see g. 11.2).
•Pull starter cord 7� Repeat the operation until the
engine starts�
•Let engine run for 2-3 minutes before subjecting it
to any load�
•Before using the tool move brake guard 4 backward,
as shown in gure 11.3 (the saw chain brake will be
deactivated)�
Note: Do not press throttle trigger 15 with
the saw chain brake on as this will lead
to overheating and increased wear of
certain elements of the tool.
•When engine is idling saw chain 2not move� For
start work push throttle interlock 16 and while holding it
in this position, push throttle trigger 15�
Switching off
•Release throttle trigger 15 - the engine will work at
idle speed�
•Move on / off switch 14 down�
Switching on (if the engine is hot)
If the engine is hot, turn the tool on as described above,
however air throttle control lever 13 must always be in
its most forward position�
Recommendations on the tool operation
Principal rules
•Perform the sawing so as to avoid the blocking of the
cutting unit in the cut (for example, consider the dropping
point of the sawn-off workpiece or a tree trunk during
tree felling). Never try to remove the blocked cutting unit
while the engine is running, stop the tool and hammer
wooden wedges into the cut to release the chain�
•Never saw with the end of the cutting unit, as in this
case, the probability of recoil is signicantly increased.
•Ensure that the saw chain does not touch the ground
during operation, as this will cause it to become blunt
quickly.
•During operation, stand so as to avoid the sawn-off
workpiece falling on you (for example, when working on
slopes, position yourself above the cut workpiece etc.).
General recommendations for the tool operation
(see g. 12)
•Carefully inspect the worksite: nothing must interfere
with your free movement, remove all stones, twigs,
shoots etc�
•Turn the tool on, as described above�
•Always hold the tool rmly with both hands, the left
hand must hold the front handle 5, while the right hand
handle 8 (see g. 12.1). Always seize grips with the
ngers. Working with one hand is prohibited.
•Keep the tool to the left of your body at some
distance�
•Prior to contact with wood the saw chain 2must run
at full speed�
•Use spiked bumper kit 3 as a lever (see g. 12.2) -
this will facilitate the implementation of operations and
make them safer. When performing lateral, oblique
and longitudinal cuts, the operator should be very
careful because spiked bumper kit 3cannot be used
in these cases�
•Rearrange the spiked bumper kit 3when sawing
trunks or thick branches. To do this, pull the tool
backwards to release the spiked bumper kit 3and
move it to the lower position� At that do not lead the
cutting unit out of the cut�
•Do not apply any intense pressure on the tool� Allow
enough time for the tool to perform the operation�
Optimal sawing results can be achieved when the saw
chain 2doesn't slow down due to overload�
•Never operate the tool while holding it with stretched
out arms�
•Be careful during the nal stage of sawing. The
sawn-off material falls down under the force of gravity
which causes a danger of injury�
•Lead the tool out of the cut only with the saw chain 2
running�
•During short pauses in the operation (for example,
when moving around the worksite) the operator can
leave the tool on� Release throttle trigger 15, move
brake guard 4to its most forward position, pull
guard 19 on the cutting unit� Do not use this method
for long breaks, in this case, always turn the tool off.
Sawing logs (see g. 13)
•Place the log on supports (or use a special saw-
horse), as shown on g. 13. The sawn-off workpiece
must fall down freely, without jamming the cutting unit�

19
English
•When sawing short workpieces these must be xed
securely (e.g. with the help of brackets).
Never saw logs lying in a pile or on the
ground, as this greatly increases the
recoil risk.
Sawing wood which is under mechanical pressure
(see g. 14)
Branches, trees or wooden materials which stay
under mechanical pressure and can be released
due to sawing, are characterized by an absolutely
unpredictable response and cause severe or even
lethal injury. In such cases be especially cautious.
Such operations can be performed only
by trained and skilled specialists.
•If the workpiece is supported from both ends (see
g. 14.1), the incision to 1/3 of thickness must be rst
made from above (A), then the workpiece must be sawn
in the same location from below (B) to prevent splitting
the wood and jamming the cutting unit of the tool�
•If the workpiece contacts the support from one end
only (see g. 14.2) an incision to 1/3 of the thickness
must be rst made from below (C) and then be sawn
off completely in the same location from above (D)�
Thus splitting the wood and jamming the cutting unit
of the tool can be prevented�
Felling trees (see g. 15)
•Always wear a protective helmet to protect the head
from falling brushwood�
•The tool can be used only for felling trees with the trunk
diameter less than the length of the tool's cutting unit�
Felling of thicker trees should be done by specialists.
•Fence the worksite off to prevent the presence of
other persons or animals on the worksite.
•Pre-determine the direction the tree will fall� This
factor is affected by the tilt and the curvature of the trunk,
the concentration of branches and the possible weight of
snow lying on them, wind direction, damage or rotting on
the trunk. It is very important to prevent a felled tree from
falling, for example, on the power lines, houses, cars etc�
•Consider and, if necessary, clear the paths for a safe
and unimpeded escape (see g. 15.1). On g. 15.1,
safe escape areas are marked with letter E, danger
areas are marked with letter F, the direction of the
fall is marked with a black arrow. Note: it is strictly
forbidden to be in the danger areas F at the time of
the tree falling, this can lead to serious injury, and
even death of the user.
•Remove the shoots under the tree, clear the lower
part of the tree trunk from small branches.
•Saw the guiding cut (G-H) (see g. 15.2) in the
direction of the falling of the tree. First, make a slanting
cut (G) (at a tilt angle of not less than 45°) and then
a horizontal cut (H). The cut depth (G-H) should be
approximately equal to 1/3 of the tree diameter�
•Then, on the opposite side of the trunk, make a
horizontal cut (I), starting at approximately 50 mm
above the cut (H) (see g. 15.3).
Note: the cut (I) must be parallel to the
cut (G-H) (see g. 15.2-15.3). Under no
circumstances must the cut go through
the entire trunk of the tree!
•The distance between the cuts (I) and (GH) should
equal approximately one tenth of the tree trunk
diameter. If the tree starts falling, immediately remove
the cutting unit from the cut and leave it in the safe
direction (see g. 15.1).
•If the tree did not fall after the cut (I) was made, its
fall must be initiated by hammering a wedge into the
horizontal cut (I).
•When the tree starts falling, you should immediately
and quickly move away in a safe direction (see
g. 15.1), beware of falling and broken branches and
twigs�
Note: If the felled tree falls on the other
tree and is stopped by it, take extra care
when releasing it. Do not operate under
the suspended tree, do not saw off the
branches and twigs supporting the felled tree, as
it is extremely dangerous. Use a winch, or contact
specialists for help.
•Cutting of the branches on the felled tree is a very
complex operation. If you do not have proper skills,
contact a professional for help�
•When sawing off branches on a felled tree, comply
with all the above safety rules�
•Do not saw off branches when perched on the felled
tree trunk.
•Do not saw off branches that the felled tree trunk
rests on�
Tool maintenance / preventive measures
Switch off the tool before fullling all procedures.
Do not draw up the fastening elements
too tight to avoid damaging the thread.
Cleaning the tool
Clean the tool casing from sawdust and wooden
waste, purge the ventilation slots thoroughly� Blow
compressed air through the ventilation slots� Do not
use caustic substances or solvents for the cleaning of

Cleaning the cutting unit
Wear protective gloves while handling
the saw chain 2.
•Unmount the cutting unit of the tool as described
above�
•Remove the saw chain 2from the guide bar 1�
•Brush off sawdust and small wooden chips from the
saw chain 2and guide bar 1�
•Oil the saw chain 2and guide bar 1to protect them
against corrosion�
•If you plan to use the tool in the near future, install
the cutting unit as described above� Put protective
guard 19 on the cutting unit of the tool�
•If you plan not to use the tool for a long period of
time, do not install the cutting unit of the tool� Wrap
the chain blade 1and saw chain 2in oiled paper and
store them in a place protected from moisture and out
of reach of children�

Saw chain condition check (see g. 16-17)
Check the condition of saw chain 2regularly�
Saw chain 2will become blunt if, in the course of the
tool operation:
•very ne dust is created;
•strong pressing on the tool is required;
•increased tool vibration is present;
•increased fuel consumption is observed�
Operating a blunt saw chain 2 is prohibited. It should
be sharpened, or replaced with a new one�
•Grip the cutting unit of the tool in a vice (see
g. 16.1).
•Use round le 27 to sharpen saw chain 2teeth�
Hold le 27 as illustrated in g. 16.2 and remember to
maintain the sharpening angles illustrated in g. 17.1.
Follow the recommendations below when sharpening
saw chain 2:
•rst, sharpen cutting teeth in one direction and
then change the position and do the same thing with
cutting teeth in the other direction;
•movements of round le 27 shall be smooth and
leisurely, the direction of movement – from you;
•if the length of cutting teeth is different, adhere to
the length of the shortest cutting tooth� Do the same
number of movements by round le 27 for each
saw chain tooth, that will ensure the same length of
cutting teeth;
•do not put too much pressure on round le 27;
•turn over round le 27 regularly to avoid its one-
sided wear�
•After sharpening saw chain 2 teeth, check and, if
necessary, grind away the depth stop (see g. 17.2).
Put template 35 on the cutting tooth, the depth stop
shall land into the slot and grind away the poking tip by
at le 36 (template 35 and at le 36 are not include
in the delivery set)�
Guide bar condition check (see g. 18)
Check the condition of guide bar 1regularly�
•Check the wear of the groove of guide bar 1� The
width of the groove of guide bar 1must match the
thickness of the drive teeth of saw chain 2, the walls of
the groove must be vertical (see g. 18.1). Guide bar 1
with a worn groove (see g. 18.2) must be replaced.
•Rough edges on the lateral surfaces of guide bar 1
must be removed with a at le (see g. 18.3).
•In order to provide even wear of guide bar 1, turn it
over after every 8 hours of operation�
Regulation of carburetor (see g. 19)
The tool is supplied with the carburetor adjusted but
additional adjustment may be required due to the
operating conditions or environment� Carburetor
adjustment is carried out by three screws:
•screw 37 (screw T) – to adjust idle speed;
•screw 38 (screw L) - to adjust low speed;
•screw 39 (screw H) - to adjust high speed�
Note: carburetor can be adjusted only
if the fuel and air lters are clean. Also,
blended fuel shall be fresh and mixed in
proper proportions.
Basic adjustment (is carried out when the engine
is powered off)
•Switch off the tool�
•Using screwdriver 24 screw in screws 38 (L)
and 39 (H) clockwise until stop. Do not draw up
the screws 38 (L) and 39 (H) too tight to avoid
damaging the thread.
•Using screwdriver 24 unscrew screws 38 (L)
and 39 (H) counterclockwise considering the number
of turns below:
for CT20101-18:
•screw 38 (screw L) - 1±¼ turns;
•screw 39 (screw H) - 1¼±⅜ turns.
for CT20102-20:
•screw 38 (screw L) - 1¾±¼ turns;
•screw 39 (screw H) - 1¾±⅜ turns.
Fine adjustment (is carried out when the engine is
hot)
•Switch on the tool and warm the engine�
•Low speed adjustment. Turn screw 38 (L)
clockwise slowly and set the highest idling speed.
Then turn screw 38 (L) counterclockwise considering
the number of turns below:
•for CT20101-18 - 1±¼ turns,
•for CT20102-20 - 1¾±¼ turns;
•Idle speed adjustment. Turn screw 37 (T) clockwise
slowly till the moment when saw chain 2starts moving,
then turn screw 37 (T) counterclockwise until saw
chain 2stop� Saw chain 2 cannot move at idle. If saw
chain 2can move by the engine at idle, irrespective of
the adjustments you carried out contact CROWN service
center - it is strongly forbidden to use the tool in this case�
•High speed adjustment. Adjustment of screw 39 (Н)
inuences the power. Turn screw 39 (H) clockwise to in-
crease the power and counterclockwise - to decrease it.
Excessive power increase may result in overspeeding
and troubles may emerge in the course of ignition� Fo-
cus on the ignition process when turning screw 39 (H)�
In case there are failures, stop turning screw 39 (H)
clockwise and slightly turn it counterclockwise.
After carrying out the adjustments above, check the
operation of the tool again:
•saw chain 2at idle shall remain motionless;
•the engine shall gain momentum quickly if you
press throttle trigger 15;
In case the conditions above are not complied with in
full, adjust the carburetor again (skip the basic stage).
If you cannot adjust it, please, contact CROWN service
center to ensure proper operation of the tool�
Drive gear condition check
•Check the condition of drive gear 32 regularly. If
drive gear 32 is cracked, chipped, or has worn teeth
over 0,5 mm, replace it� Contact the CROWN service
center�
•After replacing drive gear 32, only new saw chain 2
must be installed on it�
Cleaning the air lter (see g. 20)
Clean the air lter 42 after every 25 hours of work.
•Put the tool on at ground.
•Unlock latch 12 and remove cap 6 (see g. 20.1).
•Unscrew special nut 40 of the cover 41 (see g. 20.2).
•Remove cover 41 and air lter 42 (see g. 20.3).
