Sanding disc assembly
1. The Disc Enclosure (4) is secured to the tool with the Disc Enclosure Fittings (41) as
shown in Image A and B. Make sure the enclosure is fitted correctly with the four
screw threads horizontal at the bottom
2. Very carefully attach the Hook & Loop Adhesive Pad (45) to the Sanding Disc Base
(44 & image C). Ensure the Sanding Disc Base is completely clean of oil and grease.
Peel back the backing of the Hook & Loop Adhesive Pad and ensure they are lined up
perfectly before attaching
3. Fit the supplied Sanding Disc (22) to the hook & loop surface
4. Partially screw in the Disc Enclosure Mounting Grub Screw (42) into the thread at the
back of the Sanding Disc Base (44) then fit the Sanding Disc Base to the spindle as
shown in image D and E using the supplied Hex Key (43) as shown in Image D and E.
Use the slot at the top of the Disc Enclosure to access the Disc Enclosure Mounting
Grub Screw for tightening
5. Fit the Disc Sander Dust Extraction Assembly (11) using the Disc Sander Dust
Extraction Assembly Screws (39) and Disc Sander Dust Extraction Assembly Washers
(40)
Sanding belt section assembly
• The Tool Rest (1) is secured to the Tool Rest Mounting (21) using the Tool Rest Spring
Washer (36), Tool Rest Bolt (37) and Tool Rest Washer (38). Make sure the spring
washer is between the washer and bolt head
• The belt sander surface can be adjusted between horizontal and vertical 0-90° by
locking at the desired angle with the Belt Sander Angle Nut (2). The 0° height in the
horizontal position is adjusted with the Sanding Belt Height Adjustment Nut (27)
Changing the belt
Note: This should be read as part of the pre-operation check even if the belt is already
fitted.
1. Move the Belt Release Lever (28) forward as shown in image K
2. Remove the Belt Roller Cover (20) by removing the Belt Roller Cover Screws (19) and
the screws indicated in image L
3. Remove the screws indicated on image M and the screws on the far side in the same
positions and carefully pull the bottom metal plate away from the tool as shown in
image M
4. Carefully remove the existing belt noting the direction arrow on the rear of the belt
5. Fit the new belt ensuring the direction of the belt is correct as shown by the Direction
Indicator (26)
6. Refit the plate, screws and Belt Roller Cover
Note: Belt tracking and overall belt tension is controlled by the Belt Tension Knob (29).
Adjustment can be made by applying more or less tension to the Belt Tension Spring
Mechanism (30). This should not be necessary in normal use but may be necessary if the
belt is incorrectly tracking, slipping or the belt is excessively tensioned.
Attaching the Table
Note: The Table (6) can be positioned to either work with the Disc Sander or Belt Sander
as shown in images I and J. The horizontal plane of the Table can be adjusted but there is
no gauge built in for indicating this angle. An additional tool will be required to measure.
The Table angle can be adjusted on 3 axes to allow for the workpiece to be sanded at
any angle.
1. To use the Table with Disc Sander, insert the Table Rod (13) into the Disc Table
Mounting (33) and secure by tightening the Table Mounting Bolt (14). To use with the
Belt Sander move the Table Mounting Bolt to the Belt Table Mounting Bolt Thread (18)
and use the Belt Table Mounting (17)
2. Additional adjustments for Table Rod length and some other minor adjustments are
available on the Table Block (34) and below the Table surface using the supplied Hex
Key
3. The Mitre Guide (5) slots into the Mitre Guide Channel (7) as shown: it is locked into
the required position by tightening the Mitre Guide Angle Knob (23) and the angle is
indicated by the Mitre Angle Indicator (24)
Dust Extraction
Note: Both the Disc Sander and Belt Sander have dust extraction ports. It is highly
recommended that dust extraction is used with this tool. The hose can be connected to
which ever tool is being used at the time but a flexible 'Y' hose is recommended so both
are simultaneously connected for safety and more convenience to the operator.
1. For the Disc Sander connect the hose of the dust extraction system or vacuum cleaner
to the Disc Dust Port (12)
2. For the Belt Sander connect to the dust port as shown in image G. Allow some
additional slack in the hose connection due to angle of the belt sander varying
Pre-operational checks
• Always check that all parts or attachments are secure, and that rotating parts will not
contact guards or machine case
350W Bench Belt & Disc Sander
Operation
WARNING: Always wear suitable personal protective equipment, including eye,
hearing and respiratory protection, when operating this machine.
WARNING: Be aware that the cast metal motor housing may get hot during use.
WARNING: This tool is only suitable for one operator at a time and is designed so that a
load is applied to one side only at a time.
<exclamation triangle>Duty cycle: Do not exceed a maximum operating time of 20
minutes in every hour. It is recommended to keep to an operating time of no more than 10
minutes to reduce risk of damage to the tool from over-heating.
IMPORTANT: Fine particles of dust are created when grinding and sanding, some particles
should not be inhaled or contact skin plus there is also the risk of fine metal particles
damaging electrical tools if they enter vents. It is recommended dust extraction is used in
the workshop where this tool is fitted. If this is not possible, regularly clean and vacuum the
work area around the tool.
Switching on and off
Note: Do not switch the machine on or off when under load. Always allow the motor
to reach its full speed before applying a load, and to stop completely before leaving
unattended.
• To switch the machine on, press the 'I' on the On/Off Switch (15)
• To switch the machine off, press the 'O' on the On/Off Switch
Sanding
• Always apply the workpiece to the left of centre of the disc to prevent kickback
• Always hold the work with both hands and never allow fingers to get close to the
abrasive surface
• Move the workpiece across the sanding surface as you sand to prevent uneven wear
of the belt or disc
• Small workpieces are far more likely to cause injury. They bring fingers closer to the
abrasive surface and are more likely to be propelled towards the operator to cause
injury. Use extra caution
• Do not apply additional pressure when sanding. This will cause additional wear to the
belt, disc, drive belt and motor. In some instances it could cause the sanding belt to
snap which could injure the operator
• Contour sanding can be done on the end roller of the sanding belt section. Normally
the sanding belt section would be in the vertical position to do this
• Keep the distance between the sanding surface and the edge of the Table to
approximately 1.6mm. This will vary as you adjust the table to different angles. There
are multiple grub screws and other knobs that can be made to keep adjusting this
distance to the correct value
Accessories
• A range of accessories and consumables including an 80 grit sanding belt (186813)
is available from your Silverline stockist. Spare parts can be obtained from
toolsparesonline.com
