within a small business and also for the dedicated hobbyist with a larger budget. It is
expected to be used up to the machines maximum limit with occasional long work periods.
Suitable for income generation. Expected maximum use of 300 hours annually.

Unpacking

Open the carton, carefully unpack all of the
contents and lift the sander onto a bench.

In addition to the sander you will find three
spanners, a screwdriver and this instruction
manual.

Assembly

This machine is supplied fully assembled. It is recommended that you bolt or screw it down
to a work bench or suitable stand. The 63mm port at the back of the sander should be
connected to a suitable vacuum system or dust extractor.

Using the Sander

On/Off switch
Tilting table
T-slot for mitre fence
Tilt locking handle - there is also one at the other

end of the table.

There is a scale on the trunnion, for accurate
angle setting of the table.
If necessary, the pointer may be adjusted by
loosening the small screw holding it in place.

To switch the sander on or off, slide the red section of
the cover back. Lift the cover to expose the stop and
start buttons. The cover is spring loaded and will return
to the closed position. Hitting the red section of the
cover will activate the stop button.

Compound angles can be set by using the mitre gauge
in conjunction with the tilting table.

This sander is very easy to operate. Starting and stopping is accomplished by means of the NVR (No
Voltage Release) switch. This type of switch is designed so that if the machine is disconnected from
the mains whilst running and then reconnected, the motor will not automatically restart. The green
button of the NVR switch will have to be pressed once to start the sander.

To tilt the table, loosen both of the locking handles, move the table to the desired angle and tighten
both handles.

NOTE: It is possible to set the table up to -10° but this option must be used with extreme caution.
Considerable down force is placed on the work piece by the abrasive disc and this makes it a little
harder to move the wood across the table. The angle between the table and the disc also increases
the force with which the work piece presses against the abrasive. Should the disc start to slow down
more than normal, please reduce pressure between the work piece and the disc.

Adjustments to tilt should be made only when the sander is not running. Never force timber against
the disc, always let the machine work at its own speed.

Always switch off and unplug the sander before removing or replacing the abrasive disc.

Disc Removal and Replacement

There are two bolts securing the dust collection hood,
remove them both.

Remove the two bolts which secure the disc cover to the
base.

Remove the two bolts fixing the disc cover to the motor.

Lift the disc housing, complete with table, off the machine
and set it to one side.

Swing the top of the dust collection hood forward and lift
it clear of the base.

The abrasive disc can now be easily accessed for
replacement.

Reverse these steps to replace the disc housing and dust
hood.

Should it ever be necessary to remove the disc, the
motor spindle can be locked with the largest of the three
spanners provided and the disc unscrewed. It has a
standard right hand thread.

Optional Items

More information can be found on our website www.charnwood.net
The sander is supplied with a 300mm diameter self-adhesive backed sanding disc.

These are available from Charnwood in differing grit sizes, from 60 to 150.

Velcro Disc System

An alternate to using self-adhesive discs is to
use Velcro backed discs. They offer the huge
advantage of being able to change the disc
quickly and easily, and even refit a disc which
has previously been used.
This allows the operator to work down through
different grit sizes to achieve a better finish.

Simply purchase the Velcro hook backing pad,
VB300, which sticks to the metal disc. Our pad is
specially designed for this application and
prevents sponginess. Then use the velour
backed discs available in various grit sizes.

Sanding Disc Cleaning Stick
Dramatically increase the life of sanding discs
with this cleaning stick.

Removes clogged up pitch and sawdust when
pressed lightly against the rotating disc.

Dust Extraction It is strongly recommended that
a dust extractor is used with this sander to
prevent inhalation of harmful sanding dust.
The W413 Sander is fitted with a 63mm
diameter outlet for dust collection. A conversion
kit, W413DE, is available to adapt the outlet for
use with 100mm diameter dust extraction hose.
