SAFETY INSTRUCTIONS
Read and understand the owner’s manual and labels affixed to
the chainsaw. Learn its application and limitations as well as the
specific potential hazards. Retain these instructions for reference.
• Use safety footwear, protective clothing and a helmet with eye and
ear protection.
• Do not operate the chainsaw if you are tired,ill or under the influence
of alcohol or drugs.
• Ensure that bystanders, children and pets keep well away when
starting or cutting - at least 10m.
• Inspect the chainsaw , and in particular the bar and chain, before use
for any worn or damaged parts. Do not use until the parts are repaired
or replaced.
• Before starting the chainsaw make sure the chain is not in contact
with anything and have a clear work area and secure footing.
• Hold the chainsaw firmly with both hands when using and keep all
parts of your body away from the machine. Put the scabbard on for
transportation.
• It is recommended only to use heavy duty extension cables and these
shouldbeuncoiledbeforeuse.ItisalsorecommendedthataResidual
Current Device (RCD) Safety Plug is used.
• Do not smoke when using the chainsaw and ensure caution with the
electric cable.If the cable becomes damaged, or is cut, disconnect
from the power supply immediately.
• Always carry the chainsaw with the motor stopped, the bar and chain
to the rear and the muffler away from your body.
• Beware of small branches and saplings whipping back towards you
as you cut. When cutting a limb which is under tension, be alert to
the possibility of the limb springing back when the tension is released.
• Do not cut in high wind, bad weather or poor visibility. Check the tree
for dead branches which could fall during operation.
• Do not use in the rain or leave outside in wet weather.
• NEVER operate the chainsaw in a tree unless you are specially
trained to do so.
Always shut off the chainsaw before setting it down.
A word about KICKBACK -
Kickback can occur when the nose or tip of the guide bar touches an
object, or when the wood closes in and pinches the saw chain.
Do not rely solely on the safety devices built into your chainsaw.
• Keep a good grip on the saw with both hands - this will help you
mantain control should kickback occur.
• Ensure that the area in which you are cutting is clear and free from
obstructions so that the tip does not make contact with another log or
obstruction.
• Do not overreach or cut above shoulder height.
• Follow the manufacturer’s guidelines for sharpening and maintaining
the chain and only use replacement bars and chains specified.

ASSEMBLY
Fitting the Guide Bar and Saw Chain:
Ensure that the saw is not connected to the power supply and
wear protective gloves.
• Remove the chain cover by unscrewing the nuts on the side casing.
• Locate the guide bar onto the chainsaw making sure that the hole
on lower side of the the slot locates over the tensioning pin (12).
• Bring the tensioning pin (12) to its left hand position by turning the
screw (9) anticlockwise.
• Fit the chain over the sprocket (13) and into the groove on the
guide bar, paying attention to the correct direction of the chain. (The
arrows on the chain cover indicate the direction).
• Fit the chain cover to the power unit and fasten the nuts to finger
tightness.
• Turn the tensioner screw clockwise until the chain fits snugly on the
underside of the bar.
• Tighten the nuts securely with the bar tip held up (12-15Nm). Us-
ing gloves, check the chain for smooth rotation and correct tension
while moving by hand. Caution, chain can only be moved back-
wards by hand, be careful of the cutters. If necessary re-adjust.
Note: A new chain will stretch during its first use. Check and re-
adjust frequently.

OPERATION
Always follow the safety regulations. The chainsaw must only be
used for cutting wood. Do not use to cut other material. Vibrations
and kickback vary with different materials and the requirements of
the safety regulations would not be respected. Do not use the chain-
saw as a lever for lifting, moving or splitting objects, Do not lock it
over fixed stands. It is not necessary to force the saw into the cut. Apply
only light pressure while running the chainsaw.
• When the saw chain is caught in the cut, do not attempt to to pull it out
by force, but use a wedge or a lever to open up the cut.
• Removal of safety devices, inadequate maintenance or incorrect re-
placement of the bar or chain may increase the risk of injury due to
kickback.
To fell a tree:
• Decide on the felling direction, considering the wind, lean of the tree,
location of heavy branches and ease of completing the task after
felling.
• Clear the area around the tree and make sure you have a good foot-
hold and retreat path in the opposite direction to that in which you plan
for the tree to fall.
• Make a notch cut one-third of the way into the tree on the felling side.
• Make a felling cut from the opposite side at a slightly higher level than
the notch.
Limbing:
• Be alert to the rolling over of a cut log, especially when working on a
slope. Stand on the uphill side of the log.
• If the log is lying on the ground, cut down halfway through then turn the
log over and cut from the other side.
• If the log is free of the ground, it is sometimes easier to cut from the
bottom up and finish the cut from the top down.
Use the same principle when cutting limbs from a fallen tree that are still
attached or from a standing tree.
Watch out for the springing back of a cut limb. Do not overreach or
cut above shoulder height. Always use both your hands to hold the
saw.
Do not use this chainsaw from a ladder or any other insecure sup-
port.

OPERATION, cont’d
Chain Oil:
The chainsaw is supplied with a bottle of chain oil which must be added to the oil container
before use. The oil allows the chainsaw to operate at temperatures as low as -150C. Further
supplies of quality chain oil can be purchased from your Handy Parts stockist or garden ma-
chinery dealer.
• Unscrew the filler cap (3) and fill the container.
• By means of the set screw (4) it is possible to vary the quantity of oil delivered to the
bar. If sawing hard, dry timber or if using the entire length of the bar, turn the screw
anti-clockwise which will deliver a higher quantity of oil. For softer or wet wood, turn the
screw clockwise which will deliver a lower quantity of oil.
• Under normal conditions one fill of the oil container should last between 15-40 mins. The
capacity is 0.2 litres.
To start the chainsaw:
Before starting the chainsaw, to release the brake, pull up the front guard toward the front
handle until a “click” sound is heard.
The saw is fitted with a safety switch to prevent accidentally switching it on.
• Grasp the handle (5) with the left hand.
• Push the locking button on the left side of the switch handle then,
• Squeeze the trigger and release the locking button.
• Allow the saw to run for 2-3 minutes before using and ensure that the chain tension is
correct.
To switch off the chainsaw:
• Release the trigger. The locking button will automatically return to the locked position.
Always cover the chain and bar with the chain cover when carrying the saw and switch
off the motor.

MAINTENANCE
CHAIN BRAKE
This machine is equipped with an automatic brake to stop the saw chain rotation upon kickback.
The brake is automatically operated by inertial force, which acts on the weight fitted inside the
front guard.
The brake can also be operated manually when the front guard is pushed down to the guide bar.
To release the brake, pull up the front guard toward the front handle until a “click” sound is
heard.
To confirm brake operation:
With chainsaw stopped push brake handle forwards until a “click“ sound is heard. Ensure that
the chainsaw will now not operate. Pull the brake handle backwards to release the brake.
When the brake engages during operation, immediately release the trigger to stop the chainsaw.
CHAIN SHARPENING
Working with a blunt chain causes the chain, guide bar and drive sprocket to wear and may lead
to the chain breaking so it is important to keep the chain sharp.
It is advisable to have the chain sharpened by a specialist.
CHAIN LUBRICATION
Running the saw without chain lubrication will quickly damage the chain and guide bar.
Check the lubrication by switching on the saw and hold it with the guide bar and chain above
some light coloured paper. A steadily increasing stain caused by oil spray indicates that the
lubricating system is working correctly.
GUIDE BAR
Use a grease gun to apply a small amount of grease through the grease holes near the four
rivets holding the nose sprocket on the guide bar.
The bottom edge of the bar is exposed to relatively heavy wear and so the bar should be turned
top to bottom whenever the chain in sharpened and the groove in the bar and the oil holes
cleaned.
DRIVE SPROCKET
If the teeth of the drive sprocket show any signs of wear, the sprocket should be replaced. In
any case it should be changed with every second replacement of the chain.
CARBON BRUSHES
When the saw’s brushes are worn beyond a certain limit, a tripping device automatically stops
the motor. The brushes must be replaced by a chainsaw specialist.
