•Do not cut material greater than the rated capacity of the nibbler.

•Secure the material being cut. Never hold small pieces in your hand or across legs.

•Do not use dull or damaged punch and dies or accessories not intended for a nibbler. Replace worn punches and dies immediately.

•Do not touch punch and die during use of the nibbler.

•Never place the tool down until the punch has come to a complete stop.

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.

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.

a qualified service technician. WHEN SERVICE IS REQUIRED USE ONLY IDENTICAL REPLACEMENT PARTS.

POLARIZED PLUGS: If your tool is equipped with a polarized plug (one blade is wider than the other), this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. To reduce the risk of electric shock do not change the plug in any way.

Extension Cords

•Replace damaged cords immediately. Use of damaged cords can shock, burn or electrocute.

•If an extension cord is necessary, a cord with adequate size conductors should be used to prevent excessive voltage drop, loss of power or overheating. The table below shows the correct size to use, depending on cord length and amperage rating on the tool’s nameplate. If in doubt, use the next heavier gauge. Always use U.L. and CSA listed extension cords.

Double Insulated Tools

• Double Insulation is a design concept used in electric power tools which eliminates the need for the three wire grounded power cord and grounded power supply system. It is a recognized and approved system by Underwriter’s Laboratories, CSA and Federal OSHA authorities.

IMPORTANT: Servicing of a tool with double insulation requires care and knowledge of the system and should be performed only by

Operating the Tool

General Information

Following a few simple tips will reduce wear on the tool and the chance of injury to the user.

With the tool unplugged from the power supply and the ON/OFF Switch 1 in the “OFF” position, become familiar with handling the nibbler and learning the location of its parts.

BM 3609929430 4-04

4/22/04, 9:56 AM

Before running the nibbler, inspect the punch and die for excessive wear, and replace if necessary.

Do not exceed recommended capacities for this nibbler. Premature punch and die failure will occur when the nibbler is underor over-gaged.

• Never start the nibbler with the punch and die in contact with the material being cut.

For clean and fast cuts, hold the nibbler so that the cutting head is at a right angle to the cutting path, with the body of the tool parallel to the corrugations. Move the cutting head in and out of the corrugations, constantly keeping the head at a right angle to the material being cut.

Feed the nibbler into the work with a minimum of pressure. Let the nibbler do the work. If the nibbler doesn’t cut correctly, check for a dull punch or die. Dulling will be apparent as more pressure is required to feed the nibbler into the material. Burrs will also show along the cut edge. A harder material will dull the punch and die faster than a soft material.

Always direct the cord toward the rear, and away from the nibbler. Keep it away from sharp edges.

Secure or clamp small workpieces to be cut to prevent slippage.

Always use recommended lubricant for the materialbeingcut.Lackoflubricantwillshorten punch and die life.

Paddle Switch with “Lock-ON” feature

The Paddle Switch enables the operator to control the switch functions of “ON/OFF” and “Lock-ON”.

TO SWITCH TOOL “ON”: Squeeze and hold the paddle lever.

TO SWITCH TOOL “OFF”: Release pressure on the paddle lever. The switch is spring loaded and will return to “OFF” position automatically.

The “Lock-ON” feature, incorporated into the paddle switch, is a convenience for long operations.

TO LOCK SWITCH “ON”: After switch has been activated, PULL the front portion of the paddle lever completely BACKWARD and release pressure on the paddle lever.

TO SWITCH TOOL “OFF”: Squeeze the rear portion of paddle lever and then release the

paddle lever. The switch is spring loaded and will return to “OFF” position automatically.

Nibbling to a Scribed Line or with a Template

Cuts may be executed easily by guiding the nibbler along a template or a straight edge.

A preboring of 21mm (.827") diameter is required for internal cut-outs.

When cutting, guide the unit with a slight thrust in the cutting direction. Cutting takes place during the downward movement of the punch. The chips are ejected downward through the knurled nut 9.

Rotating the Die holder

By rotating the die holder 6, cutting can be preformed at a right angle to the forward axis of the machine. Loosen the winged screw 2and turn the die holder 6 (including the die 7 and knurled nut 9), to the right or left by 90°. Re-tighten the winged screw 2. The winged screw must engage one of the 3 holes in the die holder 6.

Tool Tips

The corrugated nibbler is especially designed for working with corrugated sheets of both trapezoidal and rectangular profiles.

Always use both hands to guide the nibbler.

Do not use force; this will lead to premature die and punch wear.

Before running the nibbler, be sure the punch and die are properly lubricated. See "Punch and Die Lubrication" section.

Never start the nibbler with the punch and die in contact with the material being cut.

Always be sure material is resting on lower die during operation.

Changing Punches and Dies

CAUTION! Unplug nibbler before changing punches and dies.

Replacing the punch

Loosen the winged screw 2 and pull the die holder 6 (including the die 7 and knurled nut 9) out of the housing 3. Slide the punch 4 sideways out of the groove and remove downward.

Oil the new punch well, insert into the groove and center.

BM 3609929430 4-04

4/22/04, 9:56 AM

Slide the die holder 6 carefully over the punch and into the housing 3. Re-tighten the winged screw 2. The winged screw must engage one of the holes in the die holder 6.

NOTE: The punch cannot be reground.

Replacing the Die

Unscrew the knurled nut 9 together with the rubber ring 8 out of the die holder 6 and remove the die 7. Remove any rust material or cutting particles that may have collected in the die holder 6.

Insert a new die 7 paying attention to the alignment of the flat surface on the side. Firmly tighten the knurled nut 9 against the resistance of the rubber ring 8.

NOTE: The die cannot be reground.

Punch and Die Lubrication

Proper lubrication is essential to prolong punch and die life, and is achieved by occasionally fully submersing the punch and die in a small container of the proper lubricant.

To further ensure a smooth cut and long punch life, always lubricate the cutting path with cutting oil. When cutting steel or stainless steel, lubricate path of cut before starting work. When cutting aluminum, lubricate path of cut while making the cut. Since the punch cuts on the downstroke, the upper side of the cut should be lubricated.

When cutting steel, use a cutting oil or an SAE 30 weight oil.

When cutting aluminum, a mixture of 7 parts kerosene and 3 parts turpentine should be used.

Should punch jam, immediately switch off nibbler, re-lubricate punch and die, and remove tension from sheet.

WARNING! The use of any accessory or attachment other than recommended in this instruction manual or the BOSCH Catalog may present a risk of personal injury.

mend that all tool service be performed at a Bosch Factory Service Center.

Tool Lubrication

Your Bosch tool has been properly lubricated and is ready for use. We recommend, that tools with gears be regreased with a special gear lubricant every time the brushes are changed.

Carbon Brushes

The brushes and commutator in your Bosch tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend that every two to six months the brushes be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used.

Bearings

After about 300-400 hours of operation, or at every second brush change, the bearings should be replaced at a Bosch Factory Service Center. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating and motor failure.

Cleaning

WARNING! To avoid accidents, always disconnect the tool from the power supply beforecleaningorperforminganymaintenance. The tool may be cleaned most effectively with compressed air. Always wear safety goggles when cleaning tools with compressed air.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

CAUTION! Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Maintenance and Service

WARNING! Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recom-
