Never use a light socket.
Never connect the live (L) or neutral (N)
wires to the earth pin marked E or .
For 115 V units with a power rating exceeding 1500
W, we recommend to fit a plug to BS4343 standard.
Using an extension cable
If an extension cable is required, use an approved
extension cable suitable for the power input of this
tool (see technical data). The minimum conductor
size is 1.5 mm2.
When using a cable reel, always unwind the cable
completely.
Also refer to the table below.

Assembly and adjustment
Prior to assembly and adjustment always
unplug the tool.
Fitting and centring the sanding belt (fig. B1 & B2)
The tool uses 75 x 533 mm sanding belts.
• Turn the clamping lever (7) clockwise until it is in
the release position.
• Remove the sanding belt (10).
• Place a new sanding belt making sure that the
arrow on the inside of the sanding belt points in
the same direction as the arrow on the machine.
• Turn the clamping lever counter-clockwise until it
is in the clamp position.
• Switch the machine on and turn the belt centring
knob (8) until the sanding belt is centred on the
roller (6).
Adjusting the front handle (fig. C)
The position of the front handle can be adjusted for
optimum control. The default position is on top of
the tool.
• Loosen the screw (11) located in the centre of
the front handle (3).
• Take the handle from the socket and place it on
the alternative socket either on top (12) or on the
front (13) of the tool.
• Make sure that the handle is properly seated.
• Tighten the screw.
DW433 - Setting the electronic speed control
(fig. A)
The belt speed is infinitely variable from 260 to
420 m/min using the electronic speed control dial (5).
• Turn the electronic speed control dial to the
required level. The correct setting, however,
is a matter of experience.
• Generally, harder materials require a higher setting.
Dust extraction (fig. D1 & D2)
Since woodworking with a sander
produces dust, always install a dustbag
designed in compliance with the
applicable directives regarding dust
emission.
