10% will cause loss of power and overheating. DEWALTtools are factory tested; if this tool does
not operate, check power supply.
COMPONENTS (Fig. 1)
A WARNING: Never modify the power tool or any part of it. Damage or personal injury could
result.
A. Punch C. Paddle Switch
B. Die D. Lock Button
INTENDED USE
The DW896 16-gauge nibbler has been designed for professional cutting at various work sites
(i.e., construction sites). DO NOT use under wet conditions or in presence of flammable liquids
or gases.
These 16-gauge nibblers are professional power tools. DO NOT let children come into contact
with the tool. Supervision is required when inexperienced operators use this tool.
ADJUSTMENTS
A WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Setting the Cutter (Fig. 2, 3)
The cutter can be set to cut in any direction relative to the body. Release the set screw in the
knurled ring (F)with key provided and unscrew the ring by rotating in a counterclockwise direction
as viewed from the cutter.
Loosen ring just enough to be able to rotate the die (B). Set the die so that the connecting
web (E) is on the opposite side of the direction of cut. Fully tighten the knurled ring and lock by
tightening the set screw.
Punch and Die Replacement (Fig 4, 5)
After a period of cutting, the punch will become blunted and require replacement. At the same
time, check the die for sharpness and replace if necessary.
1. To remove the die, release the knurled ring (F). Having removed the die (B), rotate the
motor by turning the armature fan, accessible through the side cooling slot, until the punch
retaining nut is clear of the face of the gearbox.
2. With the spanner provided, release this nut (G) counterclockwise and remove the punch (A),
Figure 5. Assemble in reverse order.
OPERATION
A WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Switches (Fig. 1)
To start tool, depress the paddle switch (C). To turn the tool off, release the paddle. The paddle
switch can be locked on by engaging the lock button (D) located near the rear of the tool, while
holding the paddle depressed. Always be sure that the tool is not locked on before plugging in.
To turn the tool off when it is locked on, squeeze and release the paddle once.
Cutting Tips (Fig. 2, 6-8)
• Make sure the knurled ring (F,Fig. 2) is tight prior to use. Keep fingers away from cutter and
other moving parts.
• The nibbler cuts a slot in the work 6 mm wide so remember to compensate for this when
marking out and calculating material requirements.
• When starting the cut from an edge, place the nibbler so the slot in the die engages the work
and the edge is against the punch, which is the moving part when cutting (Fig. 6).
• Start the nibbler by depressing the paddle switch. Hold the body parallel to the work
surface. Exert only enough forward pressure to start the nibbler cutting and maintain this
pressure. Extra pressure will not increase the rate of cut as the amount of material removed
at each cutting stroke is fixed and the rate of cut is dependent only on the speed of the
nibbler.
• The cutting line of the work should be lightly coated with oil to lubricate the punch and die
while cutting.
NOTE: Punch and die should be lubricated by immersing in a good quality cutting oil
approximately every 30 feet of cutting.
• When the cut is to be started or finished within the periphery of the work, a 1/2" (13 mm)
hole must first be drilled in the work at the start or finish point. This enables the die to be
entered or withdrawn as it is larger in diameter than the slot being cut in the work (Fig. 7).
• Circular holes should be cut in the manner shown in Figure 8, starting at the 1/2" (13 mm)
diameter hole within the circle.
MAINTENANCE
A WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Cleaning
