Electrical safety

The electric motor has been designed for one voltage only. Always
check that the power supply corresponds to the voltage on the rating
plate.
Your tool is double insulated in accordance with EN 61029;
therefore no earth wire is required.
In case of cord replacement the tool must only be repaired by an
authorized service agent or by qualified electrician.
The following cords are mandatory:
DW777 / DW771:
DW777 LX / DW771 LX:
Mains plug replacement
(U.K. & Ireland only)
DANGER:
• Should your mains plug need replacing and you are
competent to do this, proceed as instructed below. If you
are in doubt, contact an authorized D
or a qualified electrician.
• Disconnect the plug from the supply.
• Cut off the plug and dispose of it safely; a plug with bared
copper conductors is dangerous if engaged in a live socket
outlet.
• Only fit 13 Amperes BS1363A approved plugs fitted with
the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked at the
connection points of most good quality plugs. Attach the
wires to their respective points in the plug (see below).
Brown is for Live (L) (2) and Blue is for Neutral (N) (4).
• Before replacing the top cover of the mains plug ensure
that the cable restraint (3) is holding the outer sheath of the
cable firmly and that the two leads are correctly fixed at the
terminal screws.

WARNING: NEVER use a light socket.
NEVER connect the live (L) or
neutral (N) wires to the earth
pin marked E or
Fitting a mains plug to 115 V units
(U.K. and Ireland only)
• The plug should be fitted by a competent person. If you are in
doubt, contact an authorized D
electrician.
• The wires are coloured according to the following code:
live = brown
neutral = blue
• Do not connect the blue or brown wire to the earth terminal in
the plug. Connect as follows:
brown to terminal marked 'L'
blue to terminal marked 'N'

• The plug fitted should be comply with BS EN 60309 (BS4343),
16 Amps, earthing contact position 4h.
WARNING: Always ensure that the cable clamp is
correctly and securely fitted to the sheath of the cable.
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 mm
always unwind the cable completely. Also refer to the table below.

Voltage drops
In rush currents cause short-time voltage drops. Under unfavourable
power supply conditions, other equipment may be affected. If the
system impedance of the power supply is lower than 0.25
disturbances are unlikely to occur.
ASSEMBLY
WARNING: To reduce the risk of injury, turn unit off
and disconnect machine from power source before
installing and removing accessories, before adjusting or
changing set-ups or when making repairs. Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
Unpacking
The motor and guards are already assembled onto the base.
Cable clamp (fi g. 7)
Insert the cable (bb) into the cable clamp (aa). Allow enough cable for
the saw head to travel, then tighten the clamp by means of the screw.
Bench mounting (fi g. 2)
1. Holes (v) are provided in all four feet to facilitate bench mounting.
The holes are provided to accommodate different sizes of bolts.
Use either hole; it is not necessary to use both. Always mount your
saw firmly to prevent movement.
To enhance the portability, the tool can be mounted to a piece of
12.5 mm or thicker plywood which can then be clamped to your
work support or moved to other job sites and reclamped.
2. When mounting your saw to a piece of plywood, make sure that
the mounting screws do not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping
the saw to any work surface, clamp only on the clamping bosses
