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.

Do not use this power tool before you have thoroughly read and completely understood this Instruction Manual and the enclosed "General

Safety Instructions" (document number 3 41 30 465 06 0). The documents mentioned should be kept for later use and enclosed with the power tool, should it be passed on or sold.

Please also observe the relevant national industrial safety regulations.

Intended use of the power tool:

Hand-guided, reciprocating hacksaw for commercial use for cutting round and other shaped work pieces of metal, plastic and cement in weather-protected environments using the application tools and accessories recommended by FEIN.

This power tool is also suitable for use with AC generators with sufficient power output that correspond to the Standard ISO 8528, design type G2. This Standard is particularly not complied with when the so-called distortion factor exceeds 10 %. When in doubt, please refer to the generator instruction/specification guide.

Special safety instructions.

Hold the power tool by the insulated gripping surfaces when performing operations where the application tool could contact hidden wiring or its own power supply cable. Contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator.

Fasten and secure the workpiece with screw clamps or other suitable clamps to a stable surface. When holding the workpiece only by hand or against your body, it remains unstable, which can lead to loss of control.

Keep your hands well away from the saw blade. Do not place your hands in front of or underneath the saw blade. Any contact with the saw blade can cause personal injuries. The saw blade can become very hot during the sawing process.

Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. Where appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

Secure the work piece firmly. A work piece that is gripped tightly in a clamping device or vice, is more secure than if held by hand.

Do not rivet or screw any name-plates or signs onto the power tool. If the insulation is damaged, protection against an electric shock will be ineffective. Adhesive labels are recommended.

Do not use accessories which are not specifically designed and recommended by the power tool manufacturer. Safe operation is not ensured merely because an accessory fits your power tool.

Clean the ventilation openings on the power tool at regular intervals using non-metal tools. The blower of the motor draws dust into the housing. An excessive accumulation of metallic dust can cause an electrical hazard.

Before putting into operation, check the mains connection and the mains plug for damage.

Recommendation: The tool should always be supplied with power via a residual current device (RCD) with a rated current of 30 mA or less.

Hand/arm vibrations

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Handling hazardous dusts

For work procedures with this power tool where material is removed, dusts develop that can be hazardous to one's health.

Contact with or inhaling some dust types, e. g. asbestos and asbestos-containing materials, lead-containing coatings, metal, some wood types, minerals, silicate particles from materials containing stone, paint solvents, wood preservatives, antifouling paints for vessels, can trigger allergic reactions to the operator or bystanders and/or lead to respiratory infections, cancer, birth defects or other reproductive harm. The risk from inhaling dusts depends on the exposition. Use dust extraction matched appropriately for the developing dust, as well as personal protective equipment and provide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to specialists.

Wood and light-metal dust, hot mixtures of grinding dust and chemical materials can self-ignite under unfavourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the power tool and the materials being sanded, empty the dust collector/container in time, observe the material manufacturer's working instructions, as well as the relevant regulations in your country for the materials being worked.

Operating Instructions.

Guide the power tool toward the work piece only when switched on.

Guide the power tool uniformly and with light feed in the cutting direction. Excessive feed reduces the tool life of the application tools.

Stroke adjustment:

-low stroke rate for working aluminium and plastics,

-high stroke rate for working steel.

To increase the tool life of the saw blade when sawing metal, it is recommended to use a lubricating agent:

-for cuts in steel sheet: Cutting oil,

-for cuts in aluminium: Petroleum.

As an alternative, cutting paste can also be applied to the cutting line.

Using the recommended clamping devices.

Clamping fixture 9 07 02 001 00 1

For pipes with diameters to 159 mm, use the clamping fixture 9 07 02 001 00 1.

- Place the clamping chain around the work piece and insert the hooks of the grabber in the clamping chain.

-Tension the chain with the clamping-fixture handle.

-Mount the hacksaw to the retaining bolt (see "Mounting the clamping fixture").

The clamping head is readjustable for saw cuts and can be used for angle cuts.

Clamping fixture 9 07 02 004 00 6

For large pipes with diameters from 100 mm to 325 mm, use the clamping fixture 9 07 02 004 00 6 as well as saw blades with lengths of 500 mm or 600 mm, and a thickness of 2 mm. With the extension chain 3 02 31 003 00 3 (bolts 3 02 16 130 00 4), pipes with diameters to 440 mm can also be cut.

Clamping fixture 9 06 06 002 00 9

When cutting pipes with diameters to 325 mm with the 1.6 mm thick and 530 mm long saw blade, use the saw blade guide 9 06 06 002 00 9.

- With the auxiliary handle removed, mount the saw blade guide to the mounting hole of the gear head.

Clamping fixture 9 07 02 003 00 8

To cut profiled sections to a width of 310 mm and a height of 550 mm, use the clamping fixture 9 07 02 003 00 8. Its design corresponds to that of a parallel vice. The clamping jaws and the clamping head are adjustable.

Clamping fixture 9 07 02 005 00 0

When cutting pipes and round stock with outside diameters from 80 to 400 mm, use the clamp and feed device 9 07 02 005 00 0 to guide the hacksaw. A safety clutch limits the duration that the saw blade is engaged and thus increases tool life. For proper handling, please refer to Instruction Manual 3 41 00 898 06 6.

Repair and customer service.

When working metal under extreme operating conditions, it is possible for conductive dust to settle in the interior of the power tool. The total insulation of the power tool can be impaired. Blow out the interior of the power tool via the ventilation slots frequently with dry and oil-free compressed air.

Products that have come into contact with asbestos may not be sent in for repair. Dispose of products contaminated with asbestos according to the applicable country-specific regulations for such disposal.

When the machine's power supply cord is damaged, it must be replaced by the manufacturer or their representative.
