• Proceed as for cross-cutting.
Mitre cuts
• Set the mitre fence to the required angle.
• Proceed as for cross-cutting.
Compound mitre
This cut is a combination of a mitre and a bevel cut.
• Set the bevel to the angle required and proceed as for a cross-cut mitre.
Support for long pieces
• Always support long pieces.
• Support long workpieces using any convenient means such as
saw-horses or similar devices to keep the ends from dropping.
Dust extraction (fig. A2)
The machine is provided with a dust exhaust port at the rear of the
machine (16) suitable for use with dust extraction equipment featuring
57/65 mm nozzles. Supplied with the machine is a reducer port for use
of dust extraction nozzles of 34-40 mm diameter.
• During all operations, connect a dust extraction device designed in
accordance with the relevant regulations regarding dust emission.
• Ensure that the dust extraction hose in use is suitable for the
application and material being cut.
• Be aware that man-made materials such as chipboard or MDF
produce more dust particles during cutting than natural timber.

Maintenance

Your D WALT machine has been designed to operate over a long period
E
of time with a minimum of maintenance. Continuous satisfactory
operation depends upon proper tool care and regular cleaning.
Rail lock adjustment (fi g. A2 & K)
The rail lock tension has been factory-set. If you need to re-adjust,
proceed as follows:
• Turn the saw on its side.
• Lock the lock lever (13).
• Locate the hex rod (44) on the underside of the machine (fi g. K).
• Loosen the jam nut (45). Tighten the hex rod until the spring on the
locking system is compressed creating the desired tension on the rail
lock lever. Retighten the jam nut against the hex rod.
Lubrication
The motor and bearings require no additional lubrication. If raising and
lowering the blade becomes diffi cult, clean and grease the height
adjustment screws:
• Turn the saw on its side.
• Clean and grease the height adjustment threads. Use general
purpose grease.
Cleaning
WARNING: To reduce the risk of serious personal injury,
turn unit off and disconnect machine from power source
before cleaning. An accidental start-up can cause injury.
Before use, carefully inspect upper and lower guard as well as the dust
extraction tube to determine that it will operate properly. Ensure that
chips, dust or workpiece particles cannot lead to blockage of one of the
functions.
In case workpiece fragments are jammed between saw blade and
guards, disconnect the machine from the power supply and follow the
instructions given in section Mounting the saw blade. Remove the
jammed parts and reassemble the saw blade.
