Felling a tree (Fig. IV)
WARNING: ALWAYS clear an escape path first! You should establish two paths of escape, and remove
all obstacles from these routes. Paths should lead away from the tree in angles of about 45°, in directions
opposite to the planned fall direction.
1. Establish the position of the felling notch. It should be located perpendicular to the line of fall, and close to
the ground
2. Cut in to the tree at an angle of approximately 45°, and follow this cut through to about 1/5 to ¼ of the
trunk diameter. Make your second cut to remove a 45° to 90° chunk from the trunk
3. Establish the position of the felling cut. It should be exactly opposite the felling notch
4. Start the felling cut a few centimetres above the centre of the felling notch. Cut through the trunk, leaving
a 'hinge' of around 1/10 of the trunk diameter. This helps to control the fall
5. Drive wooden or plastic wedges into the felling cut to initiate the fall

WARNING: Falling trees are unpredictable. Step to one side and NEVER stand behind a falling tree. The
trunk may split, splinter or move backwards.
WARNING: NEVER run while holding a chainsaw, whether the motor is running or switched off. Turn off
the chainsaw and set it down, before making your escape.
Limbing
Note: The term 'limbing' is used for the process of removing the branches from a fallen tree.
WARNING: There is a high chance of kickback occurring during limbing operations. NEVER cut with the
nose of the Guide Bar (1). Be extremely careful to avoid touching the log or other tree limbs with the nose of
the Guide Bar.
• NEVER stand on a log while limbing. You may slip or the log may roll
• Leave the lower limbs to support the log off the ground
WARNING: Proceed with extreme caution when cutting limbs or logs that are under tension ('spring
poles'). The wood could spring back towards the operator, causing loss of control over the chainsaw,
potentially leading to severe or even fatal injury
• To cut branches off a standing tree, start with an upwards relieving cut, followed by a through-cut from
the top (Fig. V)
WARNING: When cutting free-hanging branches, the Saw Chain (2) and/or Guide Bar (1) may be pinched,
or the branch may fall. Either may cause the operator to lose control over the chainsaw. If the Saw Chain and/
or Guide Bar becomes pinched, stop the motor immediately, and remove the saw by lifting the branch. DO NOT
try to pull the saw out, as this may lead to damage or injury.
Bucking a log
Note: The term 'bucking' is used for the process of cutting logs into sections.
• NEVER stand on a log while bucking. You may slip or the log may roll
• If working on a slope, be careful and stand on the uphill side of the log you are cutting. Watch out for
rolling logs around you
• Cut only one log at a time
• Place small logs onto a sawhorse
• NEVER have any other person hold parts of the log you are cutting
• NEVER use your leg or foot to hold the log you are cutting
• Use extreme caution when cutting logs under strain. Start by making a relieving cut at the compression
side, followed by the through-cut from the tension side (Fig. VI)
WARNING: IMMEDIATELY release the On/Off Trigger Switch (11) and switch off the motor, should the Saw
Chain (2) or Guide Bar (1) be pinched inside the log. Carefully remove from the log without causing damage
to the tool.

Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out any inspection, maintenance
or cleaning.
WARNING: ALWAYS wear adequate personal protective equipment, including eye protection and oil
-resistant, cut-proof gloves, when carrying out maintenance on this chainsaw. ALWAYS ensure proper
ventilation.
WARNING: If oil is removed during maintenance, fill into a suitable sealed container and dispose of
according to laws and regulations.
WARNING: ALWAYS switch the chainsaw off and wait until all components have completely cooled,
before cleaning or carrying out any maintenance.
Note: The maintenance schedule should be adjusted according to use and environment. If the chainsaw is
used frequently, and/or if it is used in harsher environments, shorter maintenance intervals are required.
WARNING: Some of the maintenance procedures described in this manual require some general
technical skills and expertise. This chainsaw MUST ONLY be serviced by people with the necessary
competence and skill level. If in doubt, have the machine serviced by an authorised GMC service centre.
WARNING: Maintenance not covered by this manual MUST be carried out by an authorised GMC
technician. Attempting such maintenance or repairs will void the warranty.
WARNING: Use only genuine replacement parts approved by GMC for maintenance and repair. Use of
parts by others manufacturers may cause serious or fatal injury.
General inspection
• Regularly check that all the fixing screws are tight
• Inspect the supply cord of the tool, prior to each use, for damage or wear. Repairs should be carried out by
an authorised GMC service centre. This advice also applies to extension cords used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and shorten the
machine's service life. Clean the body of your machine with a soft brush, or dry cloth. If available, use
clean, dry, compressed air to blow through the ventilation holes
• Use a mild detergent and a damp cloth to clean parts contaminated with oil. Rinse with fresh water and
dry thoroughly
• Keep all electric and electronic components dry at all times
• Clean the chain, Guide Bar and sprocket after every use
Lubrication
• Lubricate moving parts after cleaning, using a suitable spray lubricant
• Regularly lubricate chain, Guide Bar and sprocket
Maintaining the guide bar
• Dismount the Saw Chain (2) and Guide Bar (1) by following the instructions in 'INSTALLING THE CHAIN
GUIDE BAR' in reverse
• Remove saw dust from the Guide Bar groove and oiling port using a small screwdriver, probe (not
included) (see Fig. VII), or compressed air
• Inspect the Guide Bar and the sprocket on its tip. Lubricate the sprocket with a suitable maintenance
spray
• Deburr, turn over or replace the Guide Bar as required
Brushes
• Over time the carbon brushes inside the motor may become worn
• Excessively worn brushes may cause loss of power, intermittent failure, or visible sparking
• To replace the brushes, remove the brush access plugs from both sides of the machine. Remove the worn
brushes and replaced with new. Replace brush access plugs. Alternatively, have the machine serviced at an
authorised service centre
Adjusting chain tension
WARNING: ALWAYS wear cut-proof gloves when touching the saw chain, to avoid injury.
• For instructions on adjusting the saw chain tension see 'Tensioning the chain' Under the 'BEFORE USE'
section
