RULES FOR SAFE OPERATION
The purpose of safety rules is to attract your attention to
possible dangers. The safety symbols and the
explanations with them, require your careful attention and
understanding. The safety warnings do not by
themselves eliminate any danger. The instruction or
warnings they give are not substitutes for proper accident
prevention measures.
SAFETY ALERT SYMBOL: Indicates caution or
warning. May be used in conjunction with other
symbols or pictures.
WARNING
Failure to obey a safety warning can result in
serious injury to yourself or to others. Always
follow the safety precautions to reduce the risk
of fire, electric shock and personal injury.
DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools which eliminates the need for earth grounding.
Whenever there is electric current in the tool there are
two complete sets of insulation to protect the user.
All exposed metal parts are isolated from the internal
metal motor components with protecting insulation.
WARNING
The double insulated system is intended to
protect the user from shock resulting from a
break in the tools internal wiring. Observe all
nomal safety precautions related to avoiding
electric shock.
IMPORTANT
Servicing of a tool with double insulation requires
extreme care and knowledge of the system and
should be performed only by a qualified service
technician. For servicing we suggest you return
the tool to your nearest Homelite Authorised
Service Centre for repair. When servicing, use
only identical Homelite replacement parts.

CHAIN SAW SAFETY PRECAUTIONS
■Grip Saw Firmly. Hold the saw securely with both
hands while the motor is running. Use a firm grip
with your thumbs and fingers encircling the
chainsaw handles.
■Clear The Work Area. Before starting cutting
operation, ensure that you have a clear work area,
secure footing and a carefully planned path of retreat
from the falling tree.
■Stay Alert. Keep all parts of the body away from the
chain saw while the motor is running. Ensure that the
chain saw is not contacting anything before starting it.
■Carrying the saw. Before picking up the saw, ensure
that it has come to a complete stop and that your
finger is off the switch (7). Carry the saw by the front
handle (1), with the guide bar (4) and the saw chain
to the rear.
■Damaged Parts. Do not operate a chain saw that is
damaged, incorrectly adjusted, or that is not completely
and securely assembled. Check to ensure that the
chain saw stops moving when the trigger is released.
■Consider the work environment. Be extremely
cautious when cutting small saplings and brush
because the thinner material may catch on the saw
chain and can be thrown towards you or pull you off
balance. Do not operate a chain saw on a tree unless
you have received specific training in how to do so.
When cutting a limb that is under tension, watch out
for spring back so that you will not be struck when the
tension in the wood fibres is released.
■Maintain the chain saw with care. Keep the cord
clear of the chain at all time. Never carry the saw by the
cord or pull on the cord to disconnect it from the socket.
■Keep the handles dry, clean and free from oil.
When storing the saw, use a scabbard or carrying case.
■How to prevent kickback. Kickback is the upward
motion of the guide bar that occurs when the saw
chain at the nose of the guide bar contacts an object.
Kickback can lead to loss of control of the chain saw
which is extremely dangerous.
To avoid kickback:
(a) Hold the chain saw firmly with both hands.
(b) Do not overreach.
(c) Do not let the nose of the guide bar contact a log,
branch, the ground or any other obstruction.
(d) Do not cut above shoulder level.
(e) Follow the details regarding sharpening and
maintenance contained in these instructions for a
better and safer performance. Follow the instructions
for lubricating and changing the guide bar.
■Wear Gloves. Wear gloves to prevent injuries while
loading or adjusting the saw blade.
■Chain Tension. Make sure that the chain tension is
correct, as specified in these instructions. Incorrect
tension may cause the chain to disengage from the
guide bar, which is extremely dangerous.

CHAIN SAW SAFETY PRECAUTIONS
■Extension Cord. When an extension cord is used
make sure:
(a) That pins on the plug of the extension cord are the
same in number, size and shape as those of the
plug on the chain saw.
(b) That extension cord is properly wired and in good
electrical condition.
(c) That the wire size is large enough for the AC
ampere rating of the chain saw.
SAVE THESE INSTRUCTIONS.

BEFORE OPERATION
CHAIN AND BAR ASSEMBLY (Fig. 1 - 3)
■Ensure the saw is unplugged from the power supply
before starting disassembly operations.
■Unscrew the knob and remove sprocket cover (5)
to expose sprocket.
■Insert the guide bar groove through the two guide pin.
Mount the saw chain on the guide bar with the cutters
facing forward on the top of the bar. Holding the chain
snugly on the guide bar with one hand, position the
loop end of the chain over the sprocket.
■Secure sprocket cover by tightening the knob (11).
SAW CHAIN TENSIONING (Fig. 4 - 5)
■Ensure that the chain saw is unplugged and the chain
is inside the guide groove of the chain bar!
■Using a crosshead screwdriver, turn the chain
tensioning knob clockwise until the saw chain is
correctly tensioned. While the knob is being tightened,
the chain bar must then be pushed upwards.
Check chain tension again. Do not tension the chain
too tightly.
IMPORTANT
When cold, it should be possible to lift the chain (3)
in the middle of the chain bar approx. 4-5 mm.
Tighten the chain tensioning knob well.
IMPORTANT
When warm, the saw chain will expand and
slacken and there is a danger of jumping off the
rail altogether. Re-tension if necessary. If the
chain is re-tensioned when hot, it must be
loosened again when the sawing work has been
completed. Otherwise, the contraction which
takes place as the chain cools would result in
excessively high tension. A new saw chain
requires a running-in-period of approx. 5 minutes.
Chain lubrication is very important at this stage.
IMPORTANT
The tension of the saw chain will affect its
performance and life. When used for the first time,
the tension can easily be set. However,
a new saw chain will stretch and should therefore
be rechecked after a little use. When checking,
be sure to disconnect the tool from the power
supply first.
■After adjusting the tension of the saw chain, then secure
the sprocket cover by tightening the knob (Fig. 5).
AUTOMATIC OILING OF SAW CHAIN (Fig. 6)
In order to minimize friction with the guide bar, the saw
chain requires lubrication while in operation. This chain
saw is equipped with in-built auto oiling system which
automatically supplies oil to the saw chain.
Never use the saw when the oil gauge (8) is below the
“minimum” mark.
■Minimum- When only approx.5 mm of oil is visible at
the lower rim if the oil gauge, the tank must be refilled.
■Maximum - Refill until the window is full.

BEFORE OPERATION
The tank holds enough oil for approximately 15 minutes
of sawing at one time. When filling the oil tank, avoid
spilling oil over the saw and ensure that sawdust etc.
does not enter the tank.
CHAIN BRAKE HANDGUARD (Fig. 7)
This chain saw is equipped with a Chain Brake Handguard
(2) to help protect you in the event of kickback. When the
Chain Brake Handguard is pushed forward by your hand,
the saw chain automatically stops.
Releasing the chain brake:
To be able to use your chainsaw again, the saw chain
must be unlocked. Firstly, switch off the machine, release
the trigger completely and then push the Chain Brake
Handguard back into the vertical position until it locks
in place. The chain brake is now fully functional again.
OPERATION
Wear eye protection while using your saw.
Wear ear protection when using saw for
extended periods.
Ensure that the oil tank is full before use.
HOLDING THE CHAIN SAW (Fig. 8)
Always grip both handles with the thumbs and fingers
encircling the handles. Ensure that your left hand is
holding the handle so that thumb is underneath.
USING THE CHAIN SAW
Always be sure of your footing and hold the chainsaw
firmly with both hands while the motor is running.
FELLING A TREE (Fig. 8 - 9)
When logging a felled tree and felling operations are
being performed simultaneously by two or more
operators, the felling operation should be separated from
the logging 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.
The chainsaw operator should keep on the uphill side of
the terrain as the tree is likely to roll or slide downhill after
it is felled. A retreat path should be planned and cleared
as necessary before cuts are started. Before 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 before felling cuts are to be made.
NOTCHING UNDERCUT (A notch cut in a tree
to direct the fall) (Fig. 10)
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of fall. Make the lower
horizontal notching cut first, this will help to avoid
pinching of either the saw chain or the guide bar when
the second notch is being made.
FELLING BACK CUT (The final cut in a tree
felling operation, made on the opposite side of
the tree from the notching undercut)
Make the felling back cut at least 50 mm 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
wood keeps the tree from twisting and falling in the
wrong direction.
Do not cut through the hinge.As the felling cut gets close
to the hinge, the tree should begin to fall. If there is any
chance that the tree may not fall in the 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 to open the cut and drop the
tree along the desired line off all. 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. Be alert for overhead limbs falling and watch
your footing.
LIMBING A TREE (Fig. 11)
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 chain saw.
BUCKING A LOG (The process of cross cutting
afelled tree or log into lengths) (Fig. 12 - 14)
Bucking is cutting a log into lengths. It is important to
make sure your footing is firm 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.

English
OPERATION
Follow the simple direction for easy cutting:
■When the log is supported along the entire length, it is
cut from the top (overbuck) (Fig. 12).
■When the log is supported on one end, cut 1/3 of the
diameter from the underside (underbuck). Then make
the finished cut by overbucking to meet the first cut
(Fig. 13).
■When the log is supported on both ends, cut 1/3 of
that diameter from the top (overbuck). Then make the
finished cut by underbucking the lower 2/3 to meet
the first cut (Fig. 14).
■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
chainsaw handles.
Do not let the chain contact the ground. After completing
the cut, wait for the saw chain to stop before you move
the chainsaw. Always stop the motor before moving from
tree to tree.
MAINTENANCE
CHAIN SHARPENING (Fig. 15 - 18)
When the chain penetrates into wood with difficulty,
it needs sharpening as follows:
■Put the chain under tension.
■Fasten the bar in a vice so that the chain can slide.
■Fasten the file to the file holder and place it on cutter
at a 35° angle.
■File with forward strokes only until all the worn out
part of the cutting edge is taken away.
■Count the number of strokes given to the cutter taken
as a reference basis and file away for the same
number of strokes on all other cutters.
■If after sharpening a few times, the depth gauge
protrudes from the template, you must reset its level
using a flat file.
■Finally, round off the depth gauge.
NOTE: We advise you to have the deep or important
sharpening carried out by a service agent who is
equipped with electric sharpener.
GUIDE BAR MAINTENANCE (Fig. 19 - 21)
■When you have finished working, clean out the groove
and the oil passages, with a special scraping hook.
■Periodically trim the sides of rails using a flat file.
If not done in the long run, the “featheredges” might
break away and damage the bar.
■If one rail is higher than the other one, it is necessary
to make it even with a flat file and then smooth them
with a file or fine grain abrasive paper.
