Maintenance
WARNING: ALWAYS wear adequate personal protective equipment, including eye protection
and oil/fuel-resistant, cut-proof gloves, when carrying out maintenance on this chainsaw.
ALWAYS ensure proper ventilation.
WARNING: Work away from naked flames, DO NOT smoke, and ensure petrol fumes or
spilled fuel cannot reach potential ignition sources.
WARNING: If fuel or oil is removed during maintenance, fill into suitable sealed containers
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 Silverline service centre.
WARNING: Maintenance not covered by this manual MUST be carried out by an authorised
Silverline technician. Attempting such maintenance or repairs will void the warranty.
WARNING: Use only genuine replacement parts approved by Silverline for maintenance
and repair. Use of parts by others manufacturers may cause serious or fatal injury.
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 or fuel.
Rinse with fresh water and dry thoroughly
• Keep all electric and electronic components dry at all times
• Clean the chain, bar and sprocket after every use
Lubrication
• Lubricate moving parts after cleaning, using a suitable spray lubricant
• Regularly lubricate chain, bar and sprocket
Maintaining the guide bar
1. Dismount the Saw Chain (2)
and Guide Bar (1) by following
the instructions in ‘Assembling
the chainsaw’ in reverse
2. Remove saw dust from the
bar groove and oiling port
using a small screwdriver,
probe (not included) (see Fig.
O), or compressed air
3. Inspect the Guide Bar and the
sprocket on its tip. Lubricate
the sprocket with a suitable
maintenance spray
4. Deburr, turn over or replace the Guide Bar as required
Adjusting chain oil delivery
• Chain oil delivery can be adjusted by inserting the supplied Slotted Screwdriver (24) into
the Chain Oil Adjustment Screw (35) at the bottom of the tool
• Increase or decrease chain oil delivery as required by working conditions, and check
adjustment as described in ‘Checking chain lubrication’
Note: If chain oil delivery cannot be increased through adjustment, thoroughly clean the
Guide Bar (1) and its oil port, and check for damage.

Felling a tree
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 engine is running of 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 (see Fig. L)
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 engine
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 (see Fig. M)
