General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

1.Keep work area clean and well lit. Cluttered or dark areas invite accidents.

2.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.

3.Keep children and bystanders away while

operating a power tool. Distractions can cause you to lose control.

Electrical Safety

4.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.

5.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.

6.Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

7.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.

8.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.

9.If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.

Personal Safety

10.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 tools may result in serious personal injury.

11.Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

12.Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. . Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

13.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.

2

14.Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

15.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.

16.If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards.

Power tool use and care

17.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.

18.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.

19.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.

21.Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

22.Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

23.Use the power tool, accessories and tool bits etc. in accordance with these instructions, 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.

Service

24.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.

25.Follow instruction for lubricating and changing accessories.

26.Keep handles dry, clean and free from oil and grease.

USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to

OPERATION

CAUTION:

•Hold the tool firmly with one hand on the main handle when performing the tool.

Pre-lubrication

Coat the cutting line with machine oil to increase the punch and die service life. This is particularly important when cutting aluminum.

Cutting method

013359

Smooth cutting is achieved by holding the tool upright and applying gentle pressure in the cutting direction. Apply tool oil to the punch about every 10 meters (32.8 feet) of mild steel or stainless steel to be cut. Light oil or kerosene should be used to keep an aluminum lubricated continuously. Failure to lubricate aluminum in the cut will cause chips to adhere to the tool, dulling the die and punch and increasing load on the motor.

Cutouts

013360

Cutouts can be done by first opening a round hole of about 42 mm (1-5/8") diameter or more in the material.

There is more vibration when cutting stainless steel than mild steel. Less vibration and better cutting is possible by adding another washer (standard equipment) beneath the die.

Use the hex wrench provided to remove the two screws and insert the washer below the die. Replace screws and tighten securely.

MAINTENANCE

CAUTION:

•Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

•Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

The tool and its air vents have to be kept clean. Regularly clean the tool's air vents or whenever the vents start to become obstructed.

Punch & die service life

Replace or sharpen punch and die after cutting the lengths indicated in the accompanying table. Their life, of course, depends upon the thickness of materials cut and lubrication conditions.

Punch	Replace after 150 m (492 ft.) of 3.2 mm (1/8") steel sheet
Die	Sharpen after 300 m (984 ft.) of 3.2 mm (1/8") steel sheet

006440

When cutting is poor even after replacing the punch, sharpen the die. Grind down the dull edge shown in the figure using a grinder. After rough-grinding the dull portion, finish with a dressing stone. Stock removal should be about 0.3 to 0.4 mm (1/64").

Consignes de sécurité générales pour outils électriques

MISE EN GARDE Veuillez lire toutes les mises en garde de sécurité et toutes les instructions.

L'ignorance des mises en garde et des instructions comporte un risque de choc électrique, d'incendie et/ou de blessure grave.

Conservez toutes les mises en garde et instructions pour référence future.

Le terme outil électrique qui figure dans les avertissements fait référence à un outil électrique branché sur une prise de courant (par un cordon d'alimentation) ou alimenté par batterie (sans fil).

Sécurité de la zone de travail

1.Maintenez la zone de travail propre et bien éclairée. Les zones de travail encombrées ou sombres ouvrent grande la porte aux accidents.

2.N'utilisez pas les outils électriques dans les atmosphères explosives, par exemple en présence de liquides, gaz ou poussières inflammables. Les outils électriques produisent des étincelles au contact desquelles la poussière ou les vapeurs peuvent s'enflammer.

3.Assurez-vous qu'aucun enfant ou curieux ne s'approche pendant que vous utilisez un outil électrique. Vous risquez de perdre la maîtrise de l'outil si votre attention est détournée.

Sécurité en matière d'électricité

4.Les fiches d'outil électrique sont conçues pour s'adapter parfaitement aux prises de courant. Ne modifiez jamais la fiche de quelque façon que ce soit. N'utilisez aucun adaptateur de fiche sur les outils électriques avec mise à la terre. En ne modifiant pas les fiches et en les insérant dans des prises de courant pour lesquelles elles ont été conçues vous réduirez les risques de choc électrique.

5.Évitez tout contact corporel avec les surfaces mises à la terre, telles que les tuyaux, radiateurs, cuisinières et réfrigérateurs. Le risque de choc électrique est plus élevé si votre corps se trouve mis à la terre.

6.N'exposez pas les outils électriques à la pluie ou à l'eau. La présence d'eau dans un outil électrique augmente le risque de choc électrique.

7.Ne maltraitez pas le cordon. N'utilisez jamais le cordon pour transporter, tirer ou débrancher l'outil électrique. Maintenez le cordon à l'écart des sources de chaleur, de l'huile, des objets à bords tranchants et des pièces en mouvement. Le risque de choc électrique est plus élevé lorsque les cordons sont endommagés ou enchevêtrés.

8.Lorsque vous utilisez un outil électrique à l'extérieur, utilisez un cordon prolongateur prévu à cette fin. Les risques de choc électrique sont moindres lorsqu'un cordon conçu pour l'extérieur est utilisé.

9.Si vous devez utiliser un outil électrique dans un endroit humide, utilisez une source d'alimentation protégée par un disjoncteur de fuite à la terre. L'utilisation d'un disjoncteur de fuite à la terre réduit le risque de choc électrique.
