Sanding
Please take note of the disc rotation (anti-clockwise) as indicated by the
arrow on the safety guard. Only work on the left hand side of the disc,
Fig
8.1
. Applying the workpiece to the left hand side of the disc will cause
downward pressure of the workpiece against the table, greatly reducing the
chance of it being thrown from the machine. Move the workpiece from left
to right whilst sanding to ensure even wear to the disc.
Warning:
Applying the workpiece to the right hand side of the
disc could cause workpiece to be thrown from the machine
and result in injury. For this reason the machine should not be
operated without the safety guard in place.
Sanding at an Angle
The work table can be tilted from 0 to 45º to allow for for sanding at an
angle,
Fig. 8.2
. To tilt the table, loosen the table lock knob and adjust to the
desired angle using the table tilt knob then re-tighten the table lock knob,
Fig 8.3
.
In addition, there are 3 angle stops on the machine which allow it to be
easily located at 0º (90º to the table), 22.5º and 45º when locked into the
sprung ball bearing, see
Fig. 8.3
.
Using the Mitre Fence
The mitre fence should be used when an accurate angle is required on the
face of workpiece to be sanded. The fence can be adjusted over a 120º
range, from 0 to 60º and 0 to -60º,
Fig. 8.4
.
Using the Disc Brake
The DS300 is equipped with a manual disc brake which can be applied by
pressing down on the brake handle,
Fig 8.5
. Only gentle pressure need
be applied and the brake should only be used after the machine has been
turned off.
Warning: Never apply the disc brake with the machine switched
on as damage to the brake or disc may occur.
In the Event of a Blockage or if the Machine Stalls
If the machine stalls during use, the likely cause is excessive pressure being
applied to the sanding disc. Simply removing the work piece from the
sanding disc will usually allow the disc to run back up to speed.
In the event that the machine stalls due to a blockage that prevents the disc
from rotating (for example, if a foreign body becomes trapped between the
table and moving disc) immediately switch the machine off by pressing the
red button marked ‘O’ on the switch and disconnect from the
electricity supply.
Locate and rectify the source of the blockage and then turn the disc by hand
to check that it rotates freely.
To re-start the machine re-connect the electricity supply and press the green
button marked ‘I’ on the switch.
In the Event of a Power Failure
The disc sander is fitted with a no volt release (NVR) switch to protect the
user against automatic starting of the machine when power is restored after
a power failure.
In the event of a power failure, first locate and rectify the source of the
failure. If the fault is within the power circuit of the workshop, there may be
an underlying cause (circuit overload etc.) that should be investigated by a
qualified electrician, before attempting to restore the power source.
Once the power is restored, the machine can be re-started by pressing the
green button marked ‘I’ on the switch.
