Sawing (Fig. A, D, E, G)
NOTICE: 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.
1. 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.
2. Hold your D WALT power tool by the front handle
e
the rear grip handle to guide the saw properly.

3. Switch the tool on before placing blade in contact with the
workpiece. Refer to Switching On and Off instruction in
this manual.

WARNING: Apply only a gentle pressure to the tool and
do not exert side pressure on the saw blade.
4. After blades have engaged the workpiece, guide the tool
back and forth in a rotating, see saw like motion as the
blades cut down through the workpiece. Refer to Figure F.
5. Once cut is complete, release the trigger switch.
To increase performance and lifetime of non-painted saw
blades, regularly apply oil to the blades and in the oil holes
(every 15–30 min.). Do not lubricate painted blades.
Regularly check the saw blade setting screws
