INTENDED USE
Your DeWALT Cross-Cut Mitre Saw has been designed for professional
cutting wood, wood products and plastics. It performs the sawing
operations of cross-cutting, bevelling and mitring easily, accurately and
safely.
This unit is designed for use with a nominal blade diameter 216 mm
carbide tip blade.
DO NOT use under wet conditions or in presence of flammable liquids
or gases.
These miter saws are professional power tools.
DO NOT let children come into contact with the tool. Supervision is
required when inexperienced operators use this tool.
WARNING! Do not use the machine for purposes other
than intended.
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: H07RN-F, 2x1.0 mm²
DW777 LX / DW771 LX: H05RR-F, 2x1.5 mm²

. When using a cable reel,
always unwind the cable completely.
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

up can cause injury.
Unpacking
The motor and guards are already assembled onto the base.
Cable Clamp (fig. 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 (fig. 2)
1. Holes (v) are provided in all four feet to facilitate bench mounting.
Two different sized holes are provided to accommodate different
sizes of bolts. Use either hole; it is not necessary to use both.
Bolts with a diameter of 8 mm and 80 mm in length is suggested.
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
where the mounting screw holes are located. Clamping at any
other point will interfere with the proper operation of the saw.
3. To prevent binding and inaccuracy, be sure the mounting surface is
not warped or otherwise uneven. If the saw rocks on the surface,
place a thin piece of material under one saw foot until the saw is
firm on the mounting surface.
Mounting the Saw Blade (fig. 1, 8–10)
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.
WARNING: The teeth of a new blade are very sharp and
can be dangerous.
WARNING: Be aware the saw blade shall be replaced in
thedescribedwayonly.Onlyusesawbladesasspecified
under Technical Data; Cat.no.: DT4320 is suggested.
1. Insert the 6 mm hex key (z) into the opposite location of the blade
shaft and hold it (fig. 8).
