DW739 (Fig. A, I)
The speed of your DW739 bandsaw is infinitely variable over a wide range (refer to the
technical data).
With the motor running, turn the blade speed adjuster

WARNING: Do not force the speed adjuster beyond its range.
Mounting and Adjusting the Rip Fence (Fig. A, J1–J5)
1. Mount a fence clamp piece ( 38 in Fig. J1) on each end of the fence (
the M6 x 65 bolts ( 37 in Fig. J1) as shown (Fig. J1, J2).
2. Put a D6 washer on each of the bolts and screw the plastic knobs
(Fig. J3).
3. Slide the fence onto the table as shown (Fig. J4). Make sure that the V-shaped lug
engages in the groove in the table (Fig. J5).
4. To set the fence, slacken the knobs 39
the scale on the table (Fig. J3).
5. Secure the fence in position by first tightening the front knob, then the rear knob. This
ensures that the fence is aligned with the blade.

Instructions for Use

WARNING: Always observe the safety instructions and applicable regulations.
• Do not force the cutting action. Allow the motor to reach full speed before cutting.
• Select an appropriate saw blade.
• Never run the machine without the guards in place.
• Do not overtension the blade.
The attention of UK users is drawn to the "woodworking machines regulations 1974" and any
subsequent amendments.
Ensure the machine is placed to satisfy your ergonomic conditions in terms of table height
and stability. The machine site shall be chosen so that the operator has a good overview and
enough free surrounding space around the machine that allows handling of the workpiece
without any restrictions.
To reduce effects of vibration make sure the environment temperature is not too cold,
machine and accessory is well maintained and the workpiece size is suitable for this machine.
Turn the knob 11 in order to properly adjust the height of the blade guard.
Switching On and Off (Fig. E1)
For reasons of security, the On/Off switch
offers a no-volt release function: should the power be shut off for some reason, the switch has
to be deliberately reactivated.
To operate
• I = ON
The tool now works in continuous operation.
• 0 = OFF
For safety reason the hinged cover is equipped with electrical interlock switch. Please close
and lock the cover carefully then otherwise the machine will not run.
Basic Saw Cuts
Always position the blade guard approximately 10 mm above the surface of the workpiece.
Ripping (Fig. K)
1. Install the rip fence as described above.
2. Set the rip fence for the width of cut required by using the scale.
3. Slowly feed the workpiece into the blade, keeping it firmly pressed onto the table and
against the fence. Allow the teeth to cut and do not force the workpiece through the
blade. The blade speed should be kept constant.

WARNING: Always use a push stick. Always switch off the tool when work is finished and
before unplugging.
