Before Use
WARNING: Always wear adequate personal protective equipment, including ear defenders,
eye protection, suitable gloves, and breathing protection.
• Always check that all parts or attachments are secure, and that rotating parts will not
foul on guards or machine case
• Check that the height of the Eye Shield (2) is appropriately adjusted
• Ensure that any ventilation holes are not obscured in any way. Hot air may be emitted
from the machine when in use
Fitting the chain clamp assembly and setting the sharpening
angle
1. Position the Chain Clamp Assembly (11) onto the base casting
2. Carefully push the bolt of the chain clamp assembly through the mounting hole in
the base casting
3. Loosely fit the Angle Locking Knob (8) on to the end of the bolt from underneath
the base casting
4. Rotate the clamp assembly until the Angle Scale (10) shows the sharpening angle
recommended by the chain manufacturer on the right side of the ‘0’ mark (turn
anticlockwise)
5. Secure by tightening the Angle Locking Knob (8)
Note: After the Chain Clamp Assembly (11) has been adjusted to the required sharpening
angle, the machine must be safely mounted to a workbench prior to use.
Adjusting the height of the eye shield
Note: The height of the Eye Shield (2) must be adjusted to compensate for wear of the
Grinding Wheel (1).
1. Loosen the two Phillips screws at either side of the Wheel Guard (3) with a Phillips
screwdriver (not supplied)
2. Adjust the position of the Eye Shield (2)
3. Retighten the screws
Cleaning and degreasing of saw chains
• Saw chains must be thoroughly cleaned, degreased and dried prior to sharpening
WARNING: Always wear cut-proof gloves when handling saw chains.
• Clean all chain links according to the chain manufacturer’s recommendations
• Refer to the lubricant manufacturer’s instructions and recommendations for chain
degreasing
Understanding saw chains
Before sharpening, familiarise yourself with the different elements of the chain. A saw
chain has left and right angled cutting surfaces (‘teeth’). These take alternate chips from
the wood as they make contact. A curved depth gauge is located in front of each tooth.
The exact angles of the teeth and the height of the depth gauges are crucial to achieving
efficient cutting.
Operation
WARNING: Always unplug the sharpener from the mains power supply before making
adjustments.
WARNING: Saw chains are extremely sharp. Handle with care. Wear suitable cut-proof
gloves.
WARNING: The grinding wheel supplied is suitable for sharpening chains with a 3/8" pitch
only. Attempting to sharpen other types of chain with this wheel may cause permanent
damage. Never attempt to sharpen objects other than saw chains with this tool.
WARNING: Ensure the chain is clean and free from oil prior to sharpening.
WARNING: Even though a quality saw chain can be sharpened multiple times, it is a
consumable item. Inspect chains for wear and damage. Discard chains that show signs
of damage, distortion or excessive wear. Do not use chains with links that do not move
freely and easily.
Switching on and off
WARNING: Keep away from the wheel when it is turning. Ensure no other person is
standing in the vicinity of the machine or in line with the wheel rotation trajectory.
Note: Do not switch the machine on/off when under load. Always allow the motor to reach
its full speed before applying load, and to stop completely before leaving unattended.
Note: Always test the grinding wheel by running it for a few seconds before making
contact with the saw chain.
• To start the machine, press the part of the On/Off Switch (5) marked '1'
• To stop the machine, press the part of the On/Off Switch (5) marked '0'
Sharpening a saw chain
Note: Ensure the tool is set up as described in ’Fitting the chain clamp assembly and
setting the sharpening angle’ in order to begin sharpening the left angled teeth.
Sharpening the left angled teeth
1. Place the chain into the Chain Clamp Assembly (11). The hook of the teeth should
face away from you
2. Lower the Chain Stop (13) so that it is resting on the rear of a left angled tooth
3. Rotate the Chain Stop Adjustment Knob (12) so that the tooth is properly positioned
when the grinding wheel is pulled down
4. Lock the chain into place by screwing the Chain Locking Knob (9) inwards
5. Check that the depth stop is correctly set. The machine head should be stopped
before the wheel can cut into the lower part of the chain. To adjust, rotate the Depth
Adjustment Knob (7)
6. Connect the machine to the mains supply and switch on
7. Grip the Handle (4) and pull the wheel down onto the blade tooth
WARNING: Remove as little material as possible and do not work too long on a tooth. The
maximum amount that can be removed from each single tooth varies from chain to chain.
Obtain this information from the chains manufacturer’s instructions and recommendations.
8. Raise the wheel and switch off. Allow the wheel to come to a complete stop, and
disconnect from mains supply before proceeding
9. Loosen the Chain Locking Knob (9) and move the chain forward so that the Chain
Stop (13) is resting on the rear of the next left angled tooth
10. Repeat the above steps to sharpen the rest of the left angled teeth
Sharpening the right angled teeth:
11. Loosen the Angle Locking Knob (8) (the machine might need to be removed from
the workbench) and rotate the clamp assembly clockwise until the sharpening angle
recommended by the chain manufacturer shows on the left side of the ‘0’ mark
12. The right angled teeth can now be sharpened in the same way as for the left
Adjusting the height of chain depth limiting gauges
• Once all the teeth have been sharpened, the depth gauges must be checked
• The depth gauges are measured against the teeth (see Fig. A). Refer to chain
manufacturer’s literature for the correct depth setting
• If the chain has been repeatedly sharpened, the chain depth limiting gauges may need
to be filed down using a flat metal file (not included) as shown in Fig. A
• File down each gauge so that they are at the distance to the cutting teeth recommended
by the manufacturer
Accessories
• Replacement grinding wheels (product code 730640) are available from your Silverline
stockist
Maintenance
WARNING: Always unplug the machine from the mains power supply before removing or
fitting any attachments, cleaning or carrying out maintenance.
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
Changing the grinding wheel
WARNING: Ensure the machine is disconnected from the mains power supply before
replacing the grinding wheel.
Note: Always replace wheels before they become excessively worn. Do not allow wheels to
wear below a diameter of 70mm.
WARNING: Never fit a grinding disc with a maximum speed lower than the no load speed
of this machine.
WARNING: Only fit grinding wheels of the correct size and arbour diameter for this
machine (see “Specifications”).
1. Unscrew the Angle Locking Knob (8) and remove the Chain Clamp Assembly (11)
from the base casting
2. Unscrew the three Phillips screws around the Wheel Guard (3)
Note: The screws are secured by small metal chains to prevent them being lost.
3. Remove the Eye Shield (2) and Wheel Guard (3)
4. Slide the Spindle Locking Pin (14) into the Spindle Locking Hole (6) with the small
diameter end first. Rotate the grinding wheel by hand until you feel the pin engage
with the motor spindle. Hold the pin in this position
5. Remove the retaining nut from the centre of the grinding wheel, using the Box
Spanner (16)
6. Remove the flange and the grinding wheel
7. Mount a new grinding wheel on the spindle and place the flange and retaining nut on
top
8. Ensure that the retaining nut and wheel guard are replaced and securely tightened
before use
WARNING: Over-tightening the retaining nut can cause the wheel to crack. Do not use
excessive force.
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
• If you suspect that the brushes may be worn, have them replaced at an authorised
service centre
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Always adhere to national regulations when disposing of power tools that are no longer
functional and are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic equipment
(WEEE), with household waste
• Contact your local waste disposal authority for information on the correct way to
dispose of power tools
