PRIOR TO USE
Points to check before starting the machine
Note: - Before using this machine a check should be
performed on all of the points listed below. It is important
before use to check the chainsaw is in good working order.
If any defects are detected then the machine should not be
used.
• Check the tension of the chain along the guide bar. A major
cause of problems with chainsaws comes as a direct result of
the tension in the chain. A loose chain will cause excessive
friction, causing wear and damage.
• Make sure the chain is well oiled. Before every use check the
oil level in the chain saw. The saw requires the chain to be well
lubricated in order to pass freely through the guide bar. This unit
requires Chainsaw Oil SAE 30. The oil level should be checked
very regularly to help reduce wear on the saw chain and guide
bar. This chainsaw is self-lubricating.
• Make sure the teeth are sharp.
• Check the power lead is in good condition.
OPERATING INSTRUCTIONS
Fitting The Guide Bar, Chain And Setting The Tension
• Make sure the chainsaw is not plugged in prior to fitting the
guide bar and chain.
NOTE: - Suitable gloves should be worn at all times when
handling the chain.
• Lay the chainsaw on its motor casing; handle side facing down.
Make sure that the chainsaw is in a stable position before going
any further.
• Remove the locking nut and plastic housing covering the drive
sprocket and locating pin.
Diagram 1
• Holding the guide bar vertically with the head at the top, insert
the chain onto the guide bar. Make sure that the chain runs
through the groove on the guide bar along both sides.
• Place the guide bar and chain onto the chainsaw body as per
the diagram below. Make sure that the guide bar is properly
positioned over the locating pin and that the tensioning pin is
also in the correct position.
Diagram 2
• With the chain and guide bar now in place run the chain around
the drive sprocket. Make sure that the direction of the blades
matches the direction of rotation of the chainsaw.
• Whilst holding the guide bar in place to stop the chain from
moving replace the plastic housing covering the drive sprocket
and tighten the locking nut. Do not over tighten.
Diagram 3
• Using a Phillips screwdriver adjust the chain tension by
screwing in a clockwise direction. This will pull the chain taught
to the guide bar.
Diagram 4
• The chain has been correctly tensioned when you can rotate the
chain by hand and it is running around the guide bar closely.
Note: - A new chain is liable to be lacking tension at first,
and will require adjusting occasionally for the first few times
in use. Over tensioning the chain will lead to premature wear.
A saw chain, which is too slack, runs the risk of
jumping out of the guide and can cause severe damage to
the machine and possibly the user.
Safe Working Practice
When using this chainsaw it is very important that all points listed
in this section be adhered to at all times. These points are listed
for the users safety and the safety of others in the surrounding
area.
Clothing And Protective Equipment
NOTE: - All of the following must be worn at all times when
using this machine
• Protective jacket conforming to prEN381 – 11 Class 0. To
provide extra protection across the shoulders, arms and front
yoke area.
• Protective trousers conforming to EN381-5 Class 1
• Chainsaw gloves conforming to EN381-7 Class O. These gloves
help prevent slippage and incorporate a special anti cut material
on the back of the hand.
• Hard hat with full face shield and ear defenders.
• Protective chainsaw boots with steel midsole and toecap.
Gaiters to provide extra protection around the shin.
Safety Rules For Making A Cut
• Ensure the protection guard (1) is in the forward position before
starting.
• Use a right hand grip to hold the chainsaw. Right hand on the
trigger and left hand on the front handle.
• Keep the left arm straight at all times for better control of the
machine.
• Hold the chainsaw firmly in both hands keeping the thumb
locked around the front handle.
• Stand to the side of the chainsaw. NEVER STAND BEHIND IT.
• Run the engine at full throttle.
• Use a low kickback saw chain and a reduced kick back
guide bar.
• Keep the chainsaw, chain, guide bar and drive sprocket properly
maintained.
• Always stand with feet well braced and your body balanced.
• Cut only wood with this chainsaw.
• Keep yourself clear of the work. Before making a cut assess the
environment. Calculate how the object being cut will fall.
Determine if the saw may be thrown unexpectedly by the
movement of the cut material.
• Never cut above shoulder level.
• Never make a cut while in a tree, or on a ladder.
• Keep others away from the cutting area. Do not allow others to
hold the wood during cutting.
Checking The Automatic Oil function
Important: the chainsaw will not operate unless the oil tank
is filled
The chain oil flow control (6) adjusts the amount of oil received
by the chain. When the hole in the knob is at the top, it is at
maximum flow and vice versa.
To check that you are getting automatic oil flow, point the tip of
the switched-on chainsaw towards a piece of paper on the floor,
if a patch of oil appears and gets larger the automatic oil flow
is working.
If the automatic oil flow is not working you need to clean the oil
way. Remove the chain bar and clean out the oil way which is the
black hole located above the thread to the left.
Kickback
Kickback is the violent backward and / or upward motion of the
chainsaw guide bar. It occurs when the chain near the tip of the
guide bar contacts on object, such as another log or branch, or
when the wood closes in and pinches the saw chain in the cut.
Kickback can be very dangerous. Be alert at all times, to guard
against a possible kickback reaction. Always be aware of the
position of the tip of the guide bar when making any cuts. The
Oregon®* chain supplied with the chainsaw has been designed
with kickback reducing features. However this does not mean that
kickback will not occur and the user should be aware of possible
kickback at all times.
Cutting In Cold Weather Conditions
Cutting frozen wood will cause rapid wear and breakage around
the rear rivet hole of cutters. Following the steps as outlined
below will help to keep the cold weather wear on the rivets to a
minimum.
• Dilute the saw chain oil 25% with clean kerosene. It is important
that in these conditions the chain is receiving oil from the saw.
• Keep the tension in the chain constant. It should be checked
and adjusted on a regular basis.
• Keep the cutters sharp. The teeth should be touched up every
hour, more often if needed. A dull chain will cause excessive
wear on the guide bar and cause the links to break very quickly.
• Check and adjust the depth gauge on the cutters every time the
saw chain is sharpened.
• Keep the guide bar clean and the oil hole open. The guide bar
is symmetrical and as such should be turned over regularly to
equalise the rail wear.
MAINTENANCE
Running In A New Chain
When this machine is supplied the chain is ready for use.
However it is possible to extend the life of the chain by following
a few simple rules.
• Soak the chain in chainsaw oil SAE 30 overnight. This will allow
the oil to penetrate all the chain components.
• Never run a chain, especially a new one, on a worn drive
sprocket. The drive sprocket system should be replaced once
every 2 chains.
• Once a new chain has been fitted run the saw at half throttle for
a couple of minute without making any cuts. This will allow the
oil to reach all parts of the guide bar and chain. It will also allow
the drive sprocket, guide bar and chain to warm up properly.
• A new chain will lose tension quickly until it is worn in
sufficiently. Keep checking and adjusting the tension for the first
few times the new chain is used.
• Do not ask too much from the new chain. Keep the first several
cuts light. Too much workload on a new chain from the start will
reduce the overall life of the chain.
Sharpening The Chain
In order to extend the saw chains life and the efficiency of the
saw the teeth should be sharpening regularly. Use a round file
with a 4mm diameter to sharpen the teeth. Always sharpen the
teeth in accordance with the original angles.
• When sharpening teeth all blades must be the same length. To
keep all teeth the same shape and size always start with the
most worn blade and file the other blades to match the length.
• Always file the blades on the same side and in the same
direction by pushing from the inside to the outside of the teeth.
In order to avoid cuts when handling the chain always wear
gloves.
• Every 3 times the blades are sharpened check the height of the
depth limiters. The depth limiters spacing is 0.5mm. Adjust the
height of the depth limiters by using a flat file. Make sure when
filing the depth limiters to follow the angle of the front angle in
order to maintain the shape of the blade.
