of the saw blades to make sure that they are
exactly parallel to the bar (6).

by pressing and turning simultaneously with the
short end of the Allen key (9).

• Press the lock-off button (2) to unlock the tool.
• To run the tool, press the variable speed switch
(1). The pressure exerted on the switch
determines the tool speed. As soon as the
variable speed switch is released the lock-off
switch is automatically activated to prevent

Sawing (fig. A, E & F)
• Clamp the workpiece on one side only to prevent
the bar from jamming in the workpiece. Should
this happen, ease open the cut with wedges to
relieve the strain on the blade. Do not try to
wrench the saw free.
• Hold your D WALT Power Tool by the front (3)
E
and the side handle (4) to guide the saw properly.
• Do not use the saw for cutting curves or pockets.
Make sure the bar end protrudes from the
workpiece.
• For long, straight cuts first draw a line on the
workpiece and follow the line.
• Make downward cuts only. Avoid cutting earth as
this will blunt the saw blades very quickly.
• When using a saw horse always cut on the
outside of the saw horse arms.
• To increase performance and lifetime of the saw
blades regularly apply oil to the blades and in the
oil holes (11) (every 15-30 min.).
• Regularly check the saw blade fixing screws (8).
