Blade Selection - DeWalt XR DCS378 Instructions Manual

Your band saw is equipped with an adjustable blade tracking
mechanism which assures proper blade tracking at all times.
The blade is properly adjusted when it is sitting fully on rubber
tires 21 and lightly touching one or both of the rear guide
bearings .

To Adjust the Blade Tracking
1. Turn and open the blade tension lever
the tracking screw .

2. Use a 13 mm wrench to loosen the lock nut
3. Use a 4 mm hex wrench
1/4 turn clockwise or counterclockwise (Fig. F).
nOTE: Turning the tracking screw clockwise(+) moves
the blade toward the guide roller, turning the tracking
screw counterclockwise(‑) moves the blade away from the
guide roller.
4. Tighten the locking nut and close the blade tension lever
and blade guard. (It will be necessary to run the saw to
observe the tracking.)
5. Observe blade tracking between runs and repeat Steps 1–4
as necessary to achieve proper blade tracking.
Blades
This portable band saw is set up for use with 0.5 mm wide,
12.7 mm high and 896 mm–899 mm long blades. DO nOT use
0.64 mm thick blades.

WARNING: The use of any other blade or accessory might
be hazardous. DO NOT use any other type of accessory
with your band saw. Blades used on stationary band saws
are of different thickness. Do not attempt to use them on
your portable unit.

Blade Selection

In general, first consider the size and shape of the work, and
the type of material to be cut. Remember, for the most efficient
cutting, the coarsest tooth blade possible should be used in
a given application, because the coarser the tooth, the faster
the cut. In selecting the appropriate number of teeth per inch
of the band saw blade, at least two teeth should contact the
work surface when the blade is rested against the workpiece.
As a rule of thumb, soft materials usually require coarse
tooth blades, while hard materials require fine tooth blades.
Where a smoother finish is important, select one of the finer
tooth blades.
Select the appropriate band saw blade according to the material
type, dimensions, and number of teeth. See Bi‑Metal Band Saw
Blade Description chart.
The following table is intended as a general guide only.
Determine the type of material and dimension of the workpiece
and select the most appropriate band saw blade.
NOTICE: Never use the band saw to cut resin materials
which are subject to melting. Melting of resin material
caused by high heat generated during cutting may cause
the band saw blade to become bound to the material,
possibly resulting in overload and burn‑out of the motor.
