Causes and operator prevention of
kickback
WARNING!
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.
WARNING!
a) With a basic understanding of kickback,
you can reduce or eliminate the
element of surprise. Sudden surprise
contributes to accidents;
b) Keep a good firm grip on the saw with
both hands, the right hand on the rear
handle and the left hand on the front
handle, when the engine is running.
Use a firm grip with thumbs and fingers
encircling the chain saw handles. A firm
grip will help you reduce kickback and
maintain control the saw. Don't let go;
c) Make sure that the area in which you
are cutting is free from obstructions.
Do not let the nose of the guide bar
contact a log, branch, or any other
obstruction that could be hit while you
are operating the saw;
d) Cut at high engine speeds;
e) Do not overreach or cut above shoulder
height;
f) Follow the manufacturer's sharpening
and maintenance instructions for the
saw chain;
g) Only use original equipment
replacement bars and chains specified
by the manufacturer or the equivalent.
Caution: The user not to use
replacement saw chain unless it has
been designed to meet the ANSI
B175.1- (current revision of standard)
kickback performance requirements on
that specific powerhead, or has been
designated as low-kickback saw chain
in accordance with ANSI B 175.1-
(current revision of standard);
Low-kickback saw chain is chain that
has met the kickback performance
requirements of ANSI B 175.1 - (current
revision of standard) (American
National Standard for Power Tools-
Gasoline-Powered Chain Saws-Safety
Requirements) when tested on the
representative sample of chain saws
below 3.8 c.i.d. specified in ANSI B
175.1- (current revision of standard)
WARNING!
Beware of kickback! Kickback can lead to
dangerous loss of control of the product
and result in serious or fatal injury to
the operator or anyone standing close

7WWW.SENIXTOOLS.COM
by! Always be alert because rotational
kickback and pinch kickback are major
product operational dangers and the
leading cause of most accidents!
Kickback may occur if the nose or tip of
the guide bar touches an object, or if wood
pinches the saw chain in the cut. In some
cases, contact with the tip of the guide
bar may cause a lightning-fast reverse
reaction, kicking the guide bar up and back
toward the operator.
Pinching the saw chain along the bottom of
the guide bar may pull the product forward
away from the operator (“skating”).
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator (“bouncing”).
Any of these reactions may cause losing
control of the product, which could result
in serious personal injury or even death.
With a basic understanding of ‘kickback’,
the element of surprise can be reduced or
eliminated. Sudden surprise contributes to
the majority of accidents. Keep a good firm
grip on the product with both hands, the
right hand on the rear handle and the left
hand on the front handle, when the engine
is running. Maintain a firm grip with your
thumbs and fingers encircling the handles.
A firm grip will help you reduce ‘kickback’
and maintain control of the product. You
should carefully read all safety warnings
and user instructions before attempting to
operate this product.
To avoid kickback:
1. Saw with guide bar at a flat angle.
2. Never work with a loose, widely
stretched or the heavily worn out chain.
3. Ensure chain is sharpened correctly.
4. Never saw above shoulder height.
5. Never work with the tip of the guide
bar.
6. Always hold the product firmly with
both hands.
7. Always use a low kickback chain.
8. Apply the metal gripping teeth for
leverage.
9. Ensure correct chain tension.
10. Only cut with the engine at high
speeds.
11. Do not let the nose of the guide bar
contact a log, branch, or any other
obstruction which could be hit while
you are operating the product.
12. Follow manufacturer’s sharpening and
maintenance instructions for the saw
chain.
13. Only use replacement guide bars
and saw chains specified by
the manufacturer or equivalent
replacements.
WARNING!
Most ‘kickback’ accidents happen during
limbing! Pay close attention to the position
of the ‘kickback’ zone of the bar when
you are ‘limbing’ branches that are under
tension.

UNPACKING
Before use of this product, familiarize yourself with all
operating features and safety rules.
Chain saw
Before beginning work, inspect the chain saw for damage
to the housing, the saw chain and the guide bar. Never
use an obviously damaged machine.
Choke knob
The choke knob opens and closes the choke valve in the
carburetor. Positions available include FULL CHOKE and
RUN.
Cutting edges on chain are sharp. Use protective
gloves when handling chain.
ALWAYS Maintain proper chain tension. 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,
guide bar, and sprocket to wear rapidly. The chain
life of the saw chain mainly depends upon sufficient
lubrication and correct tensioning. Avoid tensioning the
chain if it is hot, as this will cause the chain to become
over tensioned when it cools down.
The Chain Saw comes fully assembled. DO NOT
discard box or packing material until all parts are
examined.

2. If adjustments are needed, loosen the bar mounting
nuts at first then loosen the saw chain tension
screw by turning it counterclockwise with the spark
plug wrench(Fig. 2).
3. Do not over-tension the chain: this will lead to
excessive wear and reduces the life of both the bar
and chain.
Fig. 2
Note: The saw chain must be tensioned properly in
order to ensure safe operation. Since the saw chain
heats up during operation, its length can therefore
fluctuate. Check the chain tension every 10 minutes
of operation and adjust as necessary, particularly for
new saw chains. Slacken the saw chain after the work
is completed since it shortens when cooling down. In
doing so, you can elongate the chain’s life and prevent
damage.
1. Check the chain tension by pulling the saw chain
away from the guide bar. A properly tensioned
chain should have roughly 0.12in.( 3 mm )of
distance between itself and the bar guide (Fig. 1).

Contact an authorized service center or a similarly
qualified person to readjust idling speed!
Cutting procedure
1. To become proficient attend a recognised chain saw
training course to learn how to operate chain saws
safely and effectively. Familiarise yourself with all
the controls and switches. Practice all movements
with the product switched off.
2. Always hold the product firmly with both hands.
Front handle with the left hand and rear handle with
the right hand. Fully grip both handles at all times
during operation. Never operate the product using
only one hand.
3. Only use the product with a secure stance. Hold the
product at the right-hand side of your body(Fig.18).
4. Ensure that cutting object does not exceed the
usable cutting length of the chain saw. The tip of
guide bar shall always be kept at least 1.97in.(5 cm)
outside the outline of the wood log.
5. Ensure the saw chain is running at full speed before
it makes contact with the wood. Use the spiked
bumper to secure the product onto the wood before
starting to cut and use it as a leverage point while
cutting(Fig.19).
Chain speed
The saw chain shall not move under engine idle speed
without pressing the throttle trigger.
Checking chain lubrication
The chain lubrication should be checked after
everything else is ready before cutting.
This product is equipped with an automatic oiling
system! The oiling system automatically delivers the
proper amount of oil to the bar and chain.
Start the engine; keep it running at medium speed
and check if the chain oil is delivered as shown in the
figure(Fig.17).

6. Reset the spiked bumper at a low point when
cutting thicker logs by pulling the product slightly
backwards until the gripping teeth release, and
reposition at lower level to continue sawing. Do not
remove the product completely from the wood.
7. Do not force the saw chain while cutting, let the
chain do the work, using the gripping teeth of
spiked bumper to apply minimal leverage pressure.
8. Do not operate the product with arms fully extended
or attempt to saw areas which are difficult to reach,
or on a ladder. Never use the product above
shoulder height.
9. Optimum sawing is achieved if the chain speed
remains constant during cutting.
10. Be careful when reaching the end of the cut. The
weight of the product may change unexpectedly as
it cuts free from the wood. This can cause accidents
to the legs and feet. Always remove the product
from a wood cut while the product is running.
11. Check the chain tension and oil feeding regularly.
1. 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 utility company should be
notified immediately.
2. The product operator should keep on the uphill
side of the terrain as the tree is likely to roll or slide
downhill after it is felled.
3. 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(Fig.20).
4. 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.
5. Remove dirt, stones, loose bark, nails, staples and
wire from the tree.
Felling a tree
Notching undercut and felling back
cut
Most ‘kickback’ accidents happen during limbing! Pay
close attention to the position of the ‘kickback’ zone of
the bar when you are ‘limbing’ branches that are under
tension.
Make the notch (B) 1/3 the diameter of the tree,
perpendicular to the direction of falls. Make the lower
horizontal notching cut first. This will help to avoid
pinching either the saw chain or the guide bar when the
second notch is being made.
Make the felling back cut (A) at least 1.97in.(5 cm )
higher than the horizontal notching cut. 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 (C) 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 aluminum
to open the cut and drop the tree along the desired line
of fall.
When the tree begins to fall remove the chainsaw from
the cut, stop the engine put the chainsaw down then
use the retreat path planned. Be alert for overhead
limbs falling and watch your footing(Fig.21).

Limbing and pruning
Cutting spring poles
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 product(Fig.22).
A spring pole 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 spring poles, they are dangerous(Fig.23).

1. Follow the simple directions for easy cutting. When
the log is supported along its entire length, it is cut
from the top (overbuck)(Fig.24). Do not let the bar
and chain hit the ground.
2. When the log is supported on one end, cut 1/3 the
diameter from the underside (underbuck). Then
make the finished cut by overbucking to meet the
first cut (Fig.25).

3. When the log is supported on both ends, cut 1/3 the
diameter from the top (overbuck). Then make the
finished cut by underbucking the lower 2/3 to meet
the first cut(Fig.26).
4. When bucking on a slope always stand on the uphill
side of the log. When “cutting through”, to maintain
complete control release the cutting pressure near
the end of the cut without relaxing your grip on
the product handles. Do not let the chain contact
the ground. After completing the cut, wait for the
saw chain to stop before you move the product.
Always stop the engine before moving from tree to
tree(Fig.28).
5. Support small logs on a sawing stand or another log
while bucking(Fig.29).
6. If the wood diameter is large enough for you to
insert a soft bucking wedge without touching the
chain, you should use the wedge to hold the cut
open to prevent pinching(Fig.30).
