General Safety Rules - For All Tools

_ WARNING! Read all instructions. Failure to follow all instructions listed below

may result in electric shock, fire and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tooL

SAVE THESE INSTRUCTIONS

1) WORK AREA SAFETY

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tooL Distractions can

cause you to lose control

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not

use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electric shock

b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,

ranges and refrigerators. There is an increased risk of electric shock if your body is

earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the

power tooL Keep cord away from heat, oil, sharp edges or moving parts. Damaged

or entangled cords increase the risk of electric shock. Replace or repair damaged cords. Make sure your extension cord is in good condition. Use only 3-wire extension cords that

have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool's plug.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor

use. Use of a cord suitable for outdoor use reduces the risk of electric shock. When using an extension cord, be sure to use one heavy enough to carry the current your product will

draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length

and nameplate ampere rating, ff in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Minimum Gauge for Cord Sets

Volts Total Length of Cord in Feet

120V 0-25 26-50 51-100 101-150

3) PERSONAL SAFETY

a) Stay alert, watch what you are doing and use common sense when operating a

power tool. Do not use a power tool while you are tired or under the influence of

drugs, alcohol or medication. A moment of inattention while operating power toolsmay result in serious personal injury.

b) Use safety equipment. Always wear eye protection. Safety equipment such as

dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in the off-position before plugging

in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench or

a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and

gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. Air vents often cover moving parts and should also be avoided.

g) ff devices are provided for the connection of dust extraction and collection facilities,

ensure these are connected and properly used. Use of these devices can reduce dust- related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tooL Use the correct power tool for your application. The

correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool that

cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power

tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons

unfamiliar with the power tool or these instructions to operate the power tool Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage

of parts and any other condition that may affect the power tools operation, ff damaged, have the power tool repaired before use. Many accidents are caused by

poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to control

g) Use the power tool, accessories and tool bits etc., in accordance with these

instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power

tool for operations different from those intended could result in a hazardous situation.

5) SERVICE

a) Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

Additional Specific Safety Instructions for Nibblers

• Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring or its own cord. Contact with a "five" wire will

make exposed metal parts of the tool "live" and shock the operator.

• Cut material at or below rated capacity. Remember, material thickness increases as gauge number deceases (14 gauge is thicker than 16 gauge). 14 gauge thickness is .075" (1.9 mm); 16 gauge is .060" (1.5 mm).

• NEVER have any part of your body near the blades. Serious personal injury may result.

• Keep hands away from cutting area. A moment of inattention while operating power tools may result in serious personal injury.

• AL WAYS wear gloves when handling sheet metal The edges are sharp and can cause seri- ous personal injury.

• Firmly secure the piece of metal to be cut to prevent movement during cutting.

• ALWAYS start tool before engaging material to be cut.

• Always wear safety shoes to protect your feet from sharp metal debris on the floor.

• DO NOT use the nibbler with any kind of accessory or attachment.

• Keep all screws tight. Check periodically for loosening.

• Do not place anything into the motor housing openings.

• Clean out your tool often, especially after heavy use. Dust and grit containing metal particles often accumulate on interior surfaces and could create an electric shock hazard.

• Stay clear of end pieces that may fall after being cut off. Contact with a sharp edge could result in personal injury.

• Always keep the power cord away from the edge of the material being cut. Sharp edges can result in the cord insulation being cut. This condition may create an electrical hazard.

i_ WARNING: AL WAYS 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:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI $12.6 ($3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

i_ WARNING: Always wear proper personal hearing protection that conforms to ANSI $12.6 ($3.19) during use. Under some conditions and duration of use, noise from this product

may contribute to hearing loss.

WARNING: Always use eye protection. All users and bystanders must wear eye protection

that conforms to ANSI Z87.1. ,& WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other

construction activities contains chemicals known to cause cancer, birth defects, or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of work. To

reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic

particles.

• 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.

Motor

Your DEWALT tool is powered by a DEWALT-built motor. Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than 10% will cause loss of power

and overheating. DEWALT tools are factory tested; if this tool does not operate, check power supply.

COMPONENTS (Fig. 1)

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

result.

A. Head

B. Punch C. Shoe D. Die

E. Punch guide

F. Paddle switch G. Switch lock button

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.

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.

OPERATION (Fig. 1, 2)

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.

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) 90°

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) engage- ment 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.

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 (2-7/16 inches or

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

If the die becomes dull, replace it. Replace the old die by removing two screws at the front (Fig. 2). 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.

MAINTENANCE

_ 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.

• Check that the punch and die are sharp. If either is dull, sharpen or replace.

• Check wear plate and replace if worn.
