Using An Extension Cable; Blade Selection; Blade Speed - DeWalt DWM120 Original Instructions Manual

Additional Safety Rules – Portable
Band Saws
• Hold power tool by insulated gripping surfaces,when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord.cutting accessories
contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an electric shock.
• Keep hands away from cutting area and blade. Keep one hand
on the main handle and the other hand on the front handle to
prevent loss of control which could result in personal injury.
• Always make sure the portable band saw is clean before using.
• Always cease operation at once if you notice any abnormality
whatsoever.
• Always be sure all components are mounted properly and securely
before using tool.
• Always handle the band saw blade with care when mounting or
removing it.
• Always keep your hands out of the line of the band saw blade.
• Always wait until the motor has reached full speed before starting
a cut.
• Always keep handles dry, clean, and free of oil and grease. Hold
the tool firmly when in use.
• Always be alert at all times, especially during repetitive,
monotonous operations. Always be sure of position of your hands
relative to the blade.
• Never remove work stop.
• Stay clear of end pieces that may fall after cutting off. They may be
hot, sharp and/or heavy. Serious personal injury may result.

Using an Extension Cable

If an extension cable is required, use an approved 3–core
extension cable suitable for the power input of this tool (see
Technical Data).The minimum conductor size is 1.5 mm
maximum length
is 30 m.
When using a cable reel, always unwind the cable completely.
@ WARNING: ALWAYS use safety glasses. Everyday eyeglasses are
NOT safety glasses. Also use face or dust mask if cutting operation
is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on
the skin may promote absorption of harmful chemicals.
• The label on your tool may include the following symbols. The
symbols and their definitions are as follows:

ASSEMBLY
Blades
This portable band saw is setup for use with .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.
@ CAUTION: 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,
; the

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.
CAUTION: 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 DWM120 portable band saw is equipped with variable speed
for greater versatility. Turn the speed wheel (I) to select the desired
speed (Fig. 1). Speed 1 is the slowest speed; Speed 5 is the
fastest. Use speed settings 1–5 when connected to an AC power
supply.
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.
