Additional Safety Rules for Bench Saws
• Do not use saw blades with a body thickness greater or a width of tooth smaller than the
thickness of the riving knife.
• Make sure that the blade rotates in the correct direction and that the teeth are pointing to the
front of the bench saw.
• Be sure all clamp handles are tight before starting any operation.
• Be sure all blade and flanges are clean and the recessed sides of the collar are against the
blade. Tighten the arbor nut securely.
• Keep the saw blade sharp and properly set.
• Make sure that the riving knife is adjusted to the correct distance from the blade - maximum
5 mm.
• Never operate the saw without the upper and lower guards in place.
• Keep your hands out of the path of the saw blade.
• Disconnect the saw from the mains supply before changing blades or carrying
out maintenance.
• Use a push stick at all times, and ensure that you do not place hands closer than 150 mm from
the saw blade while cutting.
• Do not attempt to operate on anything but the designated voltage.
• Do not apply lubricants to the blade when it is running.
• Do not reach around behind the saw blade.
• Always keep the push stick in its place when not in use.
• Do not stand on top of the unit.
• During transportation make sure that the upper part of the saw blade is covered, e.g., by
the guard.
• Do not use the guard for handling or transportation.
• Do not use blades with a body thickness greater or a width of tooth smaller than the thickness
of the riving knife.
• Consider applying specially designed noise-reduction blades.
Additional Safety Rules for Table Saws
• Rebating, slotting or grooving is not allowed.
• Always use the push stick. Never cut workpiece smaller than 50 mm.
• Without additional support the machine is designed to accept the maximum workpiece
size of:
- Height 62 mm by width 600 mm by length 1500 mm
- Longer workpieces need to be supported by suitable additional table, e.g. DE3472.

WARNING: We recommend the use of a residual current device with a residual current
rating of 30mA or less.
Residual Risks
The following risks are inherent to the use of saws:
• injuries caused by touching the rotating parts
In spite of the application of the relevant safety regulations and the implementation of safety
devices, certain residual risks cannot be avoided. These are:
• Impairment of hearing.
• Risk of accidents caused by the uncovered parts of the rotating saw blade.
• Risk of injury when changing the blade.
• Risk of squeezing fingers when opening the guards.
• Health hazards caused by breathing dust developed when sawing wood, especially oak, beech
and MDF.
The following factors are of influence to noise production:
• The material to be cut.
• The type of saw blade.
• The feed force.
The following factors increase the risk of breathing problems:
• No dust extractor connected when sawing wood.
• Insufficient dust extraction caused by uncleaned exhaust filters
• Worn saw blade.
• Workpiece not exactly guided.
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.
This machine is of Class I construction; therefore earthed (grounded) connection is required.

WARNING: 115 V units have to be operated via a fail-safe isolating transformer with an
earth screen between the primary and secondary winding.
If the supply cord is damaged, it must be replaced by a specially prepared cord available
through the D WALT service organisation.
e
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the earth terminal.
26
Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 13 A.
Using an Extension Cable
If an extension cable is required, use an approved 3–core extension cable suitable for the
power input of this tool (see Technical Data).The minimum conductor size is 1.5 mm
maximum length is 30 m.
When using a cable reel, always unwind the cable completely.

Markings on Tool
The following pictograms are shown on the tool:
Read instruction manual before use.
Wear ear protection.
Wear eye protection.
Never use the mitre saw when the guard is not in place.
When using the machine in the mitre saw mode, make sure to operate
the trigger switch when switching on and off. Do not operate the
switchbox in this mode.
When using the machine in the bench saw mode, make sure that the
riving knife has been mounted. Do not use the machine without the
riving knife.
Do not use the riving knife when using the machine in the mitre saw
mode. Make sure that the riving knife is secured in the upper rest
position (Fig. A).
