WARNING: Never modify the power tool or any part of it. Damage or personal injury could
result.

C. Shoe
D. Die
INTENDED USE
The DW897 16-gauge nibblers are 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
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.
Sharpening Punches (Fig. 2)
Never cut with a blunt, dull punch (B) or die (D). Punches can be sharpened up to 1/8" (3 mm).
To remove the punch (B), loosen the head set screw (J) about 4-5 turns. Slide the shoe (C)
assembly from the head (A). Unscrew the punch (B) from the connecting rod bushing (I). Punch
may be resharpened carefully on a bench grinder with a fine grit wheel. Be careful that the punch
does not become shorter than the minimum length of 2.44 inches (61 mm). Punches shorter
than this will not engage the die sufficiently and must be replaced. The ground face must be
square to the punch axis. After grinding, carefully stone the ground edges to remove burrs. Do
not round over corners.
Reassembly of Nibbler Head (Fig. 2)
Screw the punch (B) fully into the connecting rod bushing (I). Slide the shoe (C) assembly
over the end of the punch (B) and into the head (A). NOTE: Lubrication groove in punch face
must not be exposed at front of shoe (C). Turn the shoe to desired cut orientation. Tighten set
screw (J). Next, check punch engagement.
Checking Punch Engagement (Fig. 2, 3)
Since the punch length is now changed, the punch engagement may have to be adjusted.
Check punch engagement by placing a flat blade screwdriver in the cam shaft (H) slot and
turning the shaft. Punch should dip .020" to .04" (.5 to 1.0 mm) into the die (D) at the full down
stroke position. Too much punch dip into the die will result in a loss of capacity (bottom of punch
will not clear die enough on up stroke.)
Punch Engagement Adjustment (Fig. 2, 3)
If the punch engagement should need adjustment, loosen the set screw (J) and rotate shoe (C)
either clockwise (punch deeper into die) or counterclockwise (punch out of die). Tighten set
screw firmly. Turn cam shaft (H) with screwdriver in slot to check punch engagement (moving
punch fully down). Repeat as necessary.
Die Replacement (Fig. 2)
If the die (D) becomes dull, replace it. Replace the old die by removing two screws at the front.
Install new die and tighten the screws. Recheck the punch engagement and adjust punch depth
if necessary.
Wear Plate (Fig. 3)
This tool is equipped with a wear plate (K) to increase the life of the shoe (C). The wear plate (K)
fits between the shoe (C) and the punch (B). Anytime the punch (B), punch guide (E) or die (D)
is removed, inspect the wear plate (K). If it is worn, replace it.
To remove the wear plate (K), dissassemble the punch guide (E) and die (D). Turn cam shaft (H)
with screwdriver so that punch is fully up. Slide the wear plate (K) from behind the punch (B).
Insert a new wear plate (K). Turn the cam shaft (H) with screwdriver to move punch fully
down. Replace punch guide (E) and die (D). Check punch engagement to die. Adjust punch
engagement, if necessary.
OPERATION
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 (F). To turn the tool off, release the paddle. The paddle
switch can be locked on by engaging the lock button (G) 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. 1, 2)
• Lubricate surface of material with oil. The profile nibbler is designed to cut corrugated, flat,
and box steel forms.
• The tool is factory assembled with the punch (B) oriented forward for cutting flat and shallow
corrugated material. To cut deeper corrugated metals and box sections, rotate the head (A)
90º to either side to use tool sideways.
• The shoe (C) can be aligned in three positions: left, forward, and right.
• To rotate the head (A), loosen the set screw (J). Turn the head in the desired direction.
NOTE: Do not rotate the head (A) in a complete circle as this will change the punch (B)
engagement in the die.
• Rotate the shoe (C) and turn the set screw (J) in until you feel the set screw engage a recess
in the shoe. Tighten the set screw firmly. Periodically recheck this screw for tightness.
MAINTENANCE
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.
• Check that the punch and die are sharp. If either is dull, sharpen or replace.
• Check wear plate and replace if worn.
• Periodically dip the shoe in oil.
• This is a precision tool. Use it carefully and store it in a protected place.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week.
To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when
performing this.
