•DO NOT operate a chainsaw with one hand! Serious injury to the operator, helpers, bystanders, or
any combination of these persons may result from one-handed operation. A chainsaw is intended
for two-handed use.
•DO NOT operate a chainsaw when you are fatigued, under the inuence of drugs, alcohol or
medication.
•Use safety footwear, snug-tting Chainsaw protective clothing, protective gloves, and eye, hearing
and head protection devices.
•To avoid the risk of re use caution when handling the fuel and move the chainsaw at least 10 feet
(3m) from the fuelling point before starting the engine.
•DO NOT allow other persons to be near when starting or cutting with the chainsaw.Keep
bystanders and animals out of the work area.
•DO NOT start cutting until you have a clear work area, secure footing, and a planned retreat path
from the falling tree.
•Keep all parts of your body away from the saw chain when the engine is running.
•Before you start the engine, make sure that the saw chain is not in contact with anything.
•Carry the chainsaw with the engine stopped, the guide bar and saw chain to the rear, and the
mufer away from your body.
•DO NOT operate a chainsaw that is damaged, improperly adjusted, or not completely and securely
assembled.Be sure that the saw chain stops moving when the throttle control trigger is released.
•Shut off the engine before setting the chainsaw down.
•Use extreme caution when cutting small size brush and saplings because slender material may
catch the saw chain and be whipped toward you or pull you off balance.
•When cutting a limb that is under tension, be alert for springback so that you will not be struck when
the tension in the wood bers is released.
•Keep the handles dry, clean, and free of oil or fuel mixture.
•Operate the chainsaw only in well-ventilated areas.
•DO NOT operate a chainsaw in a tree.
•All chainsaw service, other than the items listed in the user manual safety and maintenance

KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases 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 saw forward away
from the operator. PINCHING the saw chain along the TOP of the guide bar may PUSH the guide
bar rapidly back toward the operator.
Any of these reactions may cause you to lose control of the saw, which could result in serious
personal injury.
1. With a basic understanding of kickback, you can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
2. Keep a good rm 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 rm grip with thumbs and ngers
encircling the chainsaw handles. A rm grip will help you reduce kickback and maintain control of
the saw. Don’t let go.
3. 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 which could be hit while you are
operating the saw.
4. Cut at high engine speeds.
5. Do not overreach or cut above shoulder height.
6. Follow manufacturer’s sharpening and maintenance instructions for the saw chain.
7. Only use replacement bars and chains specied by the manufacturer or the equivalent.
NOTE: This appendix is intended primarily for the consumer or occasional user. These models are
intended for infrequent use by homeowners, cottagers, and campers, and for such general
applications as clearing, pruning, cutting rewood, etc. They are not intended for prolonged use. If
the intended use involves prolonged periods of operation, this may cause circulatory problems in the
user’s hands due to vibration.

Preparing to Operate the Chainsaw
Step 2 - Assembly instructions
Proper tension of saw chain is extremely important and must be checked before starting, as well as
during any cutting operation.
Taking the time to make needed adjustments to the saw chain will result in improved cutting
performance and prolonged chain life.
1. Hold nose of guide bar up and turn adjustment chain
ring CLOCKWISE to increase chain tension. Turning
chain ring COUNTERCLOCKWISE will decrease
amount of tension on chain. Ensure the chain ts snugly
all the way around the guide bar. (Fig.4)
2. After making adjustment, and while still holding nose of
bar in the uppermost position, tighten the bar retaining
button securely.Chain has proper tension when it
has a snug t all around and can be pulled around by
gloved hand. (Fig.4)
A. Loosen the bar retaining knob so they are nger tight. Decrease tension by turning the bar
adjustment chain ring COUNTERCLOCKWISE slowly.Move chain back and forth on bar.Continue
to adjust until chain rotates freely, but ts snugly. Increase tension by turning bar adjustment chain
ring CLOCKWISE.
B. When saw chain has proper tension, hold nose of bar in the uppermost position and tighten the
bar retaining knob securely.
NOTE: If chain is difcult to rotate on guide bar or if it binds, too much tension has been applied.This
requires minor adjustment as follows:
WARNING: Always stop engine and wear heavy duty gloves when handling saw chain or making saw
chain adjustments.
CAUTION: A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is normal
with a new chain, and the interval between future adjustments will lengthen quickly.
CAUTION: If saw chain is TOO LOOSE or TOO TIGHT,
the sprocket, bar, chain, and crankshaft bearings will
wear more rapidly. Study Fig. 5 for information
concerning correct cold tension (A), correct warm
tension (B), and as a guide for when saw chain needs
adjustment (C).
SAW CHAIN TENSION ADJUSTMENT
Your chainsaw is equipped with a Chain brake that reduces possibility of injury due to kickback.The
brake is activated if pressure is applied against brake lever when, as in the event of kickback,
operator’s hand strikes the lever.When the brake is actuated, chain movement stops abruptly.

FUEL AND LUBRICATION
Petrol and Oil Mix 40:1Oil Only
FUEL MIXING TABLE - 40:1
RECOMMENDED FUELS
CHAIN AND BAR LUBRICATION
Preparing to Operate the Chainsaw
Step 3 - Fuel and lubrication
Use regular grade unleaded petrol mixed with 40:1 fully synthetic 2 stroke engine oil for best
results.Use mixing ratios in Section FUEL MIXING TABLE.
WARNING: Never use straight petrol in your unit. This will cause permanent engine damage and void
the manufacturer’s warranty for that product. Never use a fuel mixture that has been stored for over
90 days.
WARNING: Lack of lubrication voids engine warranty.
WARNING: If 2-stroke lubricant other than fully synthetic is to be used, it must be a premium grade
oil for 2-stroke air cooled engines mixed at a 40:1 ratio. Do not use any 2-stroke oil product with a
recommended mixing ratio of 100:1. If insufcient lubrication is the cause of engine damage, it voids
the manufacturer’s engine warranty for that occurrence.
Fuel
Mix fuel with 2 stroke oil in an approved container.Use mixing table for correct ratio of fuel to oil. Shake
container to ensure thorough mix.
Mixing Fuel
Some conventional petrols are being blended with oxygenates such as alcohol or an ether compound
to meet clean air standards.Your engine is designed to operate satisfactorily on any petrol intended
for automotive use including oxygenated petrols.
Always rell the chain oil tank each time the fuel tank is relled.We recommend using Qualcast Chain,
Bar and Sprocket Oil, which contains additives to reduce friction and wear and to assist in the
prevention of pitch formation on the bar and chain.
Step 2 - Assembly instructions
WARNING: The purpose of the chain brake is to reduce the possibility of injury due to kickback;
however, it cannot provide the intended measure of protection if the saw is operated carelessly.
Always test the chain brake before using your saw and periodically while on the job.

Operating the Chainsaw
Step 1 - Starting the Engine (continued)
Test the CHAIN BRAKE periodically to ensure proper function.
Perform a CHAIN BRAKE test prior to initial cutting, following extensive cutting, and denitely following
any CHAIN BRAKE service.
WARNING: Activate the chain brake slowly and deliberately. Keep the chain from touching anything;
don t let the saw tip forward.
WARNING: If chain does not stop, turn engine off and take your unit to the nearest Authorized
Service Center for service.
WARNING: Don't put pressure on the saw when reaching the end of the cut. The pressure may
cause the bar and chain to rotate. If the rotating chain strikes some other object, a reactive force may
cause moving chain to strike the operator.
CHAIN BRAKE OPERATIONAL TEST
Adequate lubrication of the saw chain is essential at all times to minimize friction with the guide bar.
Never starve the bar and chain of oil. Running the saw with too little oil will decrease cutting efciency,
shorten saw chain life, cause rapid dulling of chain, and cause excessive wear of bar from
overheating. Too little oil is evidenced by smoke, bar discoloration or pitch build-up.
Your chainsaw is equipped with an automatic clutch driven oiler system. The oiler automatically
delivers the proper amount of oil to the bar and chain. As the engine speed increases, so does the oil
ow to the bar pad. There is no ow adjustment. The oil reservoir will run out at approximately the
same time as the fuel supply runs out.
1. Place saw on a clear, rm, at surface.
2. Start engine.
3. Grasp the rear handle (A) with your right hand (Fig. 10).
4. With your left hand, hold the front handle (B) [not CHAIN BRAKE lever (C)] rmly (Fig. 10).
5. Squeeze the throttle trigger to Full Throttle, then immediately activate the CHAIN BRAKE lever (C)
(Fig. 10).
6. Chain should stop abruptly. When it does, immediately release the throttle trigger.
7. If chain brake functions properly, turn the engine off and return the chain brake to the
DISENGAGED position.
TEST CHAIN BRAKE AS FOLLOWS:
NOTE: Saw chain stretches during use, particularly when it is new, and it will occasionally be
necessary to adjust and tighten it. New chain will require adjustment after about 5 minutes of
operation.

General cutting instructions
Cutting
WARNING: A retreat path (A) should be planned and cleared as necessary before cuts are started.
The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated
in Fig.11A.
WARNING: Do not cut down a tree during high or changing winds or if there is a danger to property.
Consult a tree professional. Do not cut down a tree if there is a danger of striking utility wires; notify
the utility company before making any cuts.
WARNING: Never walk in front of a tree that has been notched.
WARNING: Before making the nal cut, always recheck the area for bystanders, animals or
obstacles.
FELLING A TREE:
Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D).
Start making the upper notch cut (C) on the side of the tree facing the felling direction (E). Be sure you
don t make the lower cut too deep into the trunk.
The notch (C) should be deep enough to create a hinge (F) of sufcient width and strength. The notch
should be wide enough to direct the fall of the tree for as long as possible.
Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk
is completely cut through, control over the felling direction is lost.
Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This
will prevent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make
sure no bystanders have entered the range of the falling tree before you push it over.
Make the felling cut (D) from the other side of the tree and 1.5 - 2.0 inches (3-5 cm) above the edge
of the notch (C) (Fig.11B)
GENERAL GUIDELINES FOR FELLING TREES:
1. Use wooden or plastic wedges (A) to prevent binding the bar or chain (B) in the cut. Wedges also
control felling (Fig.11C).
2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Fig.11D).
FELLING CUT:
NOTE: Direction of fall (B) is controlled by the notching cut. Before any cuts are made, consider the
location of larger branches and natural lean of the tree to determine the way the tree will fall.
Fig. 11A
B
Fig. 11B
CAUTION: If felling a tree on sloping ground, 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.

General cutting instructions
Cutting
Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting
limbs (A) until after the log is bucked (cut) into lengths (Fig.12). Branches under tension should be cut
from the bottom up to avoid binding the chainsaw.
WARNING: As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins
to fall, remove saw from cut, stop engine, put chainsaw down, and leave area along retreat path
(Fig.11A).
WARNING: Never cut tree limbs while standing on tree trunk.
LIMBING
Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the
log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut
off is not resting on the ground. If the log is supported at both ends and you must cut in the middle,
make a downward cut halfway through the log and then make the undercut. This will prevent the log
from pinching the bar and chain. Be careful that the chain does not cut into the ground when bucking
as this causes rapid dulling of the chain.
When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into
theground (Fig.13A).
2. Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering.
Second, cut from above (overbuck) to meet rst cut and avoid pinching (Fig.13B).
3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering. Second,
underbuck to meet rst cut and avoid pinching (Fig.13C).
BUCKING
For personal safety and ease of cutting, the correct position for vertical bucking is essential (Fig.14).
VERTICAL CUTTING:
A. Hold the saw rmly with both hands and keep the saw to the right of your body while cutting.
B. Keep the left arm as straight as possible.
C. Keep weight on both feet.
NOTE: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the
log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log
being cut is securely supported.
CAUTION: While the saw is cutting, be sure the chain and bar are being properly lubricated.

CARBURETTOR ADJUSTMENT
STORING A CHAINSAW
The carburettor was preset at the factory for optimum performance. If further adjustments are
necessary, please take your unit to the nearest qualied service technician.
Storing a chainsaw for longer than 30 days requires storage maintenance. Unless the storage
instructions are followed, fuel remaining in the carburettor will evaporate, leaving gum-like deposits.
This could lead to difcult starting and result in costly repairs.
1. Remove the fuel tank cap slowly to release any pressure in the tank. Carefully drain the fuel tank.
2. Start the engine and let it run until the unit stops to remove fuel from carburettor.
3. Allow the engine to cool (approx. 5 minutes).
4. Using a spark plug wrench, remove the spark plug.
5. Pour 1 teaspoon of clean 2-stroke oil into the combustion chamber. Pull starter rope slowly several
times to coat internal components. Replace spark plug. (Fig. 19)
1. Remove spark plug.
2. Pull starter rope briskly to clear excess oil from combustion chamber.
3. Clean and gap spark plug or install a new spark plug with proper gap.
4. Prepare unit for operation.
5. Fill fuel tank with proper fuel / oil mixture. See FUEL AND LUBRICATION Section.
CAUTION: Never store a chainsaw for longer than 30 days without performing the following
procedures.
Storing a chainsaw for longer than 30 days requires storage maintenance. Unless the storage
instructions are followed, fuel remaining in the carburettor will evaporate, leaving gum-like deposits.
This could lead to difcult starting and result in costly repairs.
Lubrication of the sprocket tip is recommended after 10 hours of use or once a week, which ever
occurs rst. Always thoroughly clean guide bar sprocket tip before lubrication.
CAUTION: The sprocket tip on your new saw has been pre-lubricated at the factory. Failure to
lubricate the guide bar sprocket tip as explained below will result in poor performance and seizure,
voiding the manufacturer’s warranty.
NOTE: Store the unit in a dry place and away from possible sources of ignition such as a furnace, gas
hot water heater, gas dryer, etc.
REMOVING A UNIT FROM STORAGE
Frequent lubrication of the guide bar (railed bar which supports and carries the saw chain) sprocket
tip is required. Proper maintenance of the guide bar, as explained in this section, is essential to keep
your saw in good working condition.
GUIDE BAR MAINTENANCE
The Lube Gun (optional) is recommended for applying grease to the guide bar sprocket tip. The Lube
Gun is equipped with a needle nose tip which is necessary for the efcient application of grease to the
sprocket tip.

Maintenance
Maintenance instructions
WARNING: Wear heavy duty work gloves when handling the bar and chain.
WARNING: Always wear protective gloves during maintenance operations. Do not carry out
maintenance when the engine is hot.
WARNING: An incorrectly sharpened chain increases the risk of kickback.
WARNING: All cutting teeth must be of a similar length. Different length of the teeth can cause rough
run of the chain or its rupture, as well.
WARNING: After you have sharpened the cutter teeth 3 to 4 times, have the saw chain sharpened by
an authorised dealer. They will also sharpen the depth of the limiter , which provides the distance.
1. Press the STOP switch down.
2. Clean the guide bar sprocket tip.
3. Using the Lube Gun (optional), insert needle nose into the lubrication hole and inject grease until it
appears at outside edge of sprocket tip (Fig. 20).
4. Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has been
greased.
Most guide bar problems can be prevented merely by keeping the chainsaw well maintained.
Insufcient guide bar lubrication and operating the saw with chain that is TOO TIGHT will contribute to
rapid bar wear.
To help minimize bar wear, the following guide bar maintenance procedures are recommended.
Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle and
depth. For the inexperienced chainsaw user, we recommend that the saw chain be professionally
sharpened by the nearest professional Service Center. If you feel comfortable sharpening your own
saw chain, special tools are available from the professional Service Center. For non-experienced
users of the chainsaw, we recommend to have the chain sharpened by a specialist in any authorised
service centre.
1. To sharpen the saw chain, use the suitable sharpening tools:
- Round chain le ø5/32”(4mm).
- File leading
- Chain measuring calibre.
These tools can be bought in any specialsed stores.
2. To gain well shaped sawdust particles, use sharp chain. If there appears wooden powder, you
must sharpen the saw chain.
3. Minimum length of the teeth must be 4mm. If they are shorter, remove the saw chain.
4. Angles, which the teeth are under, must be followed.
5. To sharpen the chain basically, make 2 to 3 pulls of the le from the inside out.
NOTE: It is not necessary to remove the saw chain to lubricate the guide bar sprocket tip. Lubrication
can be done on the job.

Maintenance
Maintenance instructions
WARNING: A sharp chain produces well dened chips. When your chain starts to produce sawdust,
it is time to sharpen.
WARNING: Proper adjustment of the depth gauge is as important as proper sharpening of the chain.
WARNING: Never mount a new chain on a worn sprocket or self-aligning ring.
CHAIN SHARPENING - The pitch of the chain (Fig. 21) is 3/8” LoPro x .050”.
Sharpen the chain using protective gloves and a round le of ø5/32” (4mm).
Always sharpen the cutters only with outward strokes (Fig. 22) observing the values given in Fig. 21.
After sharpening, the cutting links must all have the same width and length.
After every 3-4 times the cutters have been sharpened you need to check the height of the depth
gauges and, if necessary, lower them using the at le and template supplied optional, then round off
the front corner. (Fig. 23)
GUIDE BAR - The bar should be reversed every 8 working hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean using a bar groove cleaner (optional). (Fig. 24)
Check the bar rails frequently for wear and, if necessary, remove the burs and square-up the rails
using a at le. (Fig.25)
BAR WEAR - Turn guide bar frequently at regular intervals (for example, after 5 hours of use), to
ensure even wear on top and bottom of bar.
OIL PASSAGES -Oil passages on the bar should be cleaned to ensure proper lubrication of the bar
and chain during operation.
CHAIN TENSION:
Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the
bar, but loose enough to be pulled around by hand.
CHAIN MAINTENANCE
A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the
break-in period, and the interval between future adjustments will begin to lengthen quickly.
NOTE: The condition of the oil passages can be easily checked. If the passages are clear, the chain
will automatically give off a spray of oil within seconds of starting the saw. Your saw is equipped with
an automatic oiler system.

Maintenance
Maintenance instructions
Always make sure the automatic oiler system is working properly. Keep the oil tank lled with Chain,
Bar and Sprocket Oil.
Adequate lubrication of the bar and chain during cutting operations is essential to minimize friction
with the guide bar.
Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease
cutting efciency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of
bar from overheating. Too little oil is evidenced by smoke or bar discoloration.
WARNING: Never have more than 3 links removed from a loop of chain. This could cause damage
to the sprocket.
WARNING: Always stop unit and disconnect spark plug before performing all of the recommended
remedies below except remedies that require operation of the unit.
