Figure - DeWalt DCS374 User Manual

WARNING: This tool has no provision
to lock the switch in the ON position,
and should never be locked ON by any
other means.
The variable speed trigger switch will give you added
versatility. The further the trigger is depressed the
higher the speed of the saw.
CAUTION: Use of very slow speed is
recommended only for beginning a cut.
Prolonged use at very slow speed may
damage your saw.
LED Worklight (Fig. 1)
CAUTION: Do not stare into
worklight. Serious eye injury could
result.
There is a worklight (L) located above the blade.
The worklight is activated when the trigger switch is
depressed, and will automatically turn off 20 seconds
after the trigger switch is released. If the trigger switch
remains depressed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate
work surface and is not intended to be used as a
flashlight.
Blades
This portable band saw is designed to use
.020" (0.5 mm) thick, 1/2" (12.5 mm) wide and
44-7/8" (1140 mm) long blades. DO NOT use .025
(.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 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
Blade Speed
Your DCS374 portable band saw is equipped with
variable speed for greater versatility. Turn the speed
wheel (K) to select the desired speed (Fig. 1). Speed
1 is the slowest speed; Speed 5 is the fastest. Use
speed settings 1–5.
When cutting copper, brass, bronze, aluminum,
cast iron, angle iron, and mild steel, use a higher
speed.
When cutting plastic pipe, tougher steels, chrome
steel, tungsten steel, stainless steel, and other
problem materials, use low speed.
NOTE: When cutting plastic pipe, higher speeds
may melt plastic.
Blade Tracking (Fig. 1)
WARNING: To reduce the risk of
serious personal injury, turn tool
off and remove the battery pack
before making any adjustments or
removing/installing attachments or
accessories. An accidental start-up
can cause injury.
Your band saw is equipped with an adjustable blade
tracking mechanism which assures proper blade
tracking at all times. The back edge of a properly
aligned blade will run lightly against one or both of
the back up rollers in the blade guides. (The pressure
between the edge of the blade and the roller will be
very slight and will not damage either the blade or
the roller.)
To Adjust the Blade Tracking
1. Use a 1/2" (13 mm) wrench to loosen the
adjustment locking nut (G), shown in Figure 2 by
turning it one or two turns counterclockwise.
2. Use a screwdriver to turn the adjustment screw
(H) 1/4 turn. Turning the screw clockwise will
move the blade up toward the blade guide
rollers. Turning the screw counterclockwise will
move the blade down away from the rollers.
3. Adjust so that the back edge of the blade lightly
touches the rollers then securely tighten the
adjustment locking nut. (It will be necessary
