Blade Tracking
@ WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source 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 1 by turning it one or two turns
counterclockwise.
2. Use a screwdriver to turn the tracking screw 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 locking nut. (It will be necessary to plug
the saw in and run it to observe the tracking.)
4. Observe blade tracking between runs and repeat Steps 1–4 as
necessary to achieve proper blade tracking.
Removing and Installing Blades
@ WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.
@ CAUTION: Cut Hazard. Blade tension lever is under spring
pressure. Maintain control of lever when releasing blade tension.
TO REMOVE BLADE (FIG. 1, 2)
1. Rotate the blade tension lever (H) clockwise until it stops to release
tension in blade.
2. Turn the saw over and place it on a workbench or table with the
cord to the left.
3. Begin removing the blade at the blade guard (M) and continue
around the pulleys (L). When removing the blade, tension may
be released and the blade may spring free. SAW BLADES ARE
SHARP. USE CARE IN HANDLING THEM.
4. Inspect the guide rollers (F1, F2) and remove any large chips which
may be lodged in them. Lodged chips can prevent rotation of the
guide rollers and cause flat spots on the guide rollers.
5. Rubber tires (N) are mounted on the pulleys (L). The rubber tires
should be inspected for looseness or damage when changing the
blade. Wipe any chips from the rubber tires on the pulleys. This will
extend tire life and keep the blade from slipping. If any looseness
or damage occurs, the tool should be brought to an authorized
DEWALT service center for repair or replacement as soon as
possible. Continued use of the tool with loose or damaged rubber
tires will cause unstable travel of the band saw blade.
TO INSTALL BLADE (FIG. 1, 3–5)
1. Position the blade so that the teeth are on the bottom and angled
toward the work stop, as shown in Figures 1 and 3.
2. Slip the blade into the guide rollers, as shown in Figure 4.
3. Holding the blade in the guide rollers, place it around both pulleys
(L) and through the work stop (E), as shown in Figure 5.
4. Make sure that the blade is fully inserted into the guide rollers and
positioned squarely against the rubber tires.
5. Rotate the blade tension lever (H) counterclockwise until it stops
and then gently turn the saw over so that the pulleys rest on your
work bench or table and. Make sure the teeth face away from the
bandsaw (Fig. 1, 3).
6. Turn the speed wheel to low speed (1) and then turn the saw on
and off a few times to ensure that the blade is seated properly.
Multi-position Bail Handle (Fig. 1)
A bail handle is provided for carrying the tool and for use as an
additional handle. Assemble the bail handle in one of the milti-
positions (forward, 45º or straight up) shown in Figure 1. When
adjusting the bail handle from one position to the other, loosen the
bail handle knob and move the handle to one of the three positions
and tighten knob.
Adjustments
@ WARNING: To reduce the risk of serious personal injury, turn tool
off and disconnect tool from power source before making any
adjustments or removing/installing attachments or accessories. An
accidental start-up can cause injury.
WORK STOP ADJUSTMENT
To support large workpieces, the work stop should be lowered
following these steps:
1. Loosen the two screws (R), shown in Figure 1, with the hex wrench
provided.
2. Move the work stop (E) to the desired position (Fig 5).
3. Securely tighten screws (R).
OPERATION
Motor
Be sure your power supply agrees with the voltage marked on
the nameplate. 110 Volts AC 60 Hz means alternating current
only. Voltage decrease of more than 10% will cause loss of power
and over heating. All DEWALT tools are factory-tested. If this tool
does not operate, check the power supply line for blown fuses
and the plug and receptacle for proper contact.There are certain
applications for which this tool was designed.
This band saw is designed to cut various types of material up to
4-3/4" (120.7 mm) diameter or 5" (127 mm) x 4-3/4" (120.7 mm)
rectangular shape at 90º.
@ WARNING: Thoroughly remove any oil or grease from the
workpiece before securing in a vise or other clamping device. If the
workpiece is not secure, it may come loose during the cutting and/
or cause breakage, which may result in serious personal injury.
@
WARNING: Never connect the power tool unless the available AC
power is of the same voltage as that specified on the nameplate of
the tool. Never connect this power tool to a DC power source.
@ WARNING: Laceration Hazard. If the power cord is connected to
the power source with the trigger switch turned ON the power tool
will start suddenly and could cause a serious accident.
Trigger Switch
To start the tool, squeeze the trigger switch (C). To turn the tool off,
release the switch.
