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. Prevent unintentional starting. Make sure that the switch is in the “OFF” position before connecting the pneumatic tool to the compressed-air supply. When your finger is on the switch while carrying the pneu- matic tool or when connecting the pneumatic tool to the compressed-air supply while it is switched on, acci- dents can occur. Remove any adjustment tools or spanners before switching on the pneumatic tool. An adjustment tool or spanner left attached to a rotating part of a pneumatic tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. This enables better control of the pneumatic tool in unexpected situations. If you experience tingling, numbness or pain while working, inform your supervisor and consult a doctor. 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. 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 dust-related hazards. Pneumatic tool use and care Do not exceed the maximum air pressure specified on the tool. Do not overload the pneumatic tool. Use the application tool intended for your work. The correct pneumatic tool will do the job better and safer at the rate for which it is designed. Do not use a pneumatic tool that has a defective switch. A pneumatic tool that cannot be controlled with the switch is dangerous and must be repaired. The pneumatic tool is initially lubricated. During initial commissioning, excess oil may escape and come into contact with the operator. Disconnect the energy supply before making any pneu- matic tool adjustments, changing accessories, or plac- ing the pneumatic tool aside. This safety measure prevents accidental starting of the tool. Store idle pneumatic tools out of the reach of children. Do not allow persons unfamiliar with the pneumatic tool or these instructions to operate the pneumatic tool. Pneumatic tools are dangerous in the hands of untrained users. Maintain the pneumatic tool with care. Check for mis- alignment or binding of moving pneumatic tool parts, breakage of parts and any other condition that may affect the pneumatic tool’s operation. Have damaged parts repaired before using the pneumatic tool. Many accidents are caused by poorly maintained pneumatic tools. Keep cutting tools sharp and clean. Properly main- tained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Check the saw blade for damage before starting work. Use only undamaged saw blades. If the saw blade jams, switch off the tool and hold it steady. Determine and correct the cause for the jam- ming. Use splitting wedges. Use the pneumatic tool, accessories, application tools, etc. according to these instructions and as specified for this specific type of pneumatic tool. Take into consider- ation the working conditions and the activities to be carried out. Use of pneumatic tools for operations dif- ferent from those intended could result in hazardous situations. Use the auxiliary handle provided with the pneumatic tool. Loss of control over the pneumatic tool can cause injuries. Hold the pneumatic tool firmly with both hands and keep proper footing and balance at all times. The pneu- matic tool is guided more secure with both hands. Do not work materials containing asbestos. Asbestos is considered carcinogenic. Make sure that the saw blade is firmly clamped. 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 per- sonal injuries. The saw blade can become very hot dur- ing the sawing process. Apply the pneumatic tool to the work piece only when switched-on. Danger of kickback or loss of control over the pneumatic tool. Do not rivet or screw any name-plates or signs onto the pneumatic tool. Adhesive labels are recommended. Do not use accessories that have not been especially designed or released by the pneumatic tool manufac- turer. Safe operation is not ensured only because an accessory fits your pneumatic tool. Pay attention to hidden conductors/leads, gas and water pipes. Before beginning to work, check the working area, e. g., with a metal detector. Service Have your pneumatic tool repaired only through a qual- ified repair person and only using original replacement parts. This will ensure that the safety of the pneumatic tool is maintained. Special safety instructions. Hold the tool by the insulated gripping surfaces when performing operations where the application tool could contact hidden wires. Contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator. Never carry the pneumatic tool by the hose. 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.18

Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing pro- tectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye pro- tection must be capable of stopping flying debris gener- ated 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. Renew stickers and warning indications on the pneu- matic tool when aged and worn. Do not direct the application tool against yourself, other persons or animals. Danger of injury from sharp or hot application tools. Handling hazardous dusts For work procedures with this 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 coat- ings, metal, some wood types, minerals, silicate parti- cles 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 pro- vide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to special- ists. Wood and light-metal dust, hot mixtures of sanding dust and chemical materials can self-ignite under unfa- vourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the pneumatic 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. Starting Operation. Carry out the following steps each time before using the product. – Check the proper condition and operation of the product. – Check the tight seating of the application tool. Connecting to the compressed-air supply. For trouble-free operation of the pneumatic tool, use a maintenance unit consisting of water separator, oil lubricator and compressed-air regulator. Please check whether the pressure in the compressed-air supply corresponds to the pressure indicated on the rating plate of the pneumatic tool. – Blow out the hose before connecting. Always use locking pins and hose safety cables when using universal rotary couplings (baronet couplings). The hose should have a minimum diameter of 13 mm. The opening of the valve and the coupling should have a diameter of at least 8 mm. Before beginning to work, check if the oiler installed in the handle is filled. The correct setting of the oiler and a sufficient supply of oil is required for optimal function of the oiler. External oilers are only effective to a hose length of 5 m (max.), as otherwise the oil remains in the hose and does not reach the machine. Fill the oil reservoir as required with FEIN special motor oil 3 21 32 045 00 0 (high-quality hydraulic oil, grade: HLP/ISO-VG46). Do not use automotive engine oils, as these are not suitable for pneumatic tools. Vibration and noise emission values The vibration and noise emission values given in these instructions have been measured according to a meas- urement method standardized in EN 62841 and can be used to compare pneumatic tools with each other. They are also suitable for a preliminary assessment of vibration and noise exposure. The given vibration and noise emission values rep- resent the main applications of the pneumatic tool. However, if the pneumatic tool is used for other appli- cations, with deviating application tools or insufficient maintenance, the overall vibration values and the noise emission values may differ. This can significantly increase the vibration and noise exposure over the total working period. For an accurate estimation of vibration and noise expo- sure, the durations when the equipment is switched off or running but not actually in use should also be taken into account. This may significantly reduce the vibration and noise exposure over the total working period. Identify additional safety measures to protect the operator from the effects of vibration and noise such as: Maintain the pneumatic tool and the accessories, keep the hands warm, organization of work patterns. Operating Instructions. Guide the pneumatic tool toward the work piece only when switched on. Guide the pneumatic tool uniformly and with light feed in the cutting direction. Excessive feed considerably reduces the tool life of the application tools. Hold the pneumatic tool by the gripping surface during the complete sawing. Switch off the pneumatic tool immediately after sawing. 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. When uncoupling hose couplings, first shut the ball valve, then actuate the pneumatic tool, and then uncou- ple. Do not uncouple the hose coupling until after the compressed air has been completely relieved.19

Remove the auxiliary handle and mount the support for free hand working to the hacksaw via the clamping head and the two gear head mounting holes for the auxiliary handle. The saw blade goes through the opening. Repair and customer service. Carry out the following steps once per week: – Pour a small quantity of petroleum directly into the air intake of the pneumatic tool. – Start the pneumatic tool for 10 to 15 seconds. In this period, the petroleum will seep out of the pneumatic tool along with the accumulated debris. – Adding a small quantity of oil into the air intake after the cleaning will benefit the performance of the motor. Further lubrication is covered by the oiler installed in the handle. Maintain and clean the pneumatic tool every 300 work hours or every 6 months. When the pneumatic tool’s hose is damaged, it must be replaced with a specially prepared hose, available from your FEIN customer service agent. Correct setting of the oiler: Under operating pressure (6 bar) and with the filler plug (1) open, the oil must bubble. One oil filling is sufficient for approx. 8 operating hours. After removing the screw plug (2), the setting screw (3) can be accessed. Tightening (turning clockwise) the setting screw reduces the oil feed, releasing (turning anticlockwise) the setting screw increase the oil feed to the machine. In most cases, tightening or releasing by ¼ to ½ thread will be sufficient. Allow a Ø 2 mm clearance in the passage hole. Check the correct oiler setting by applying a paper test: Hold a white sheet of paper in front of the air outlet of the machine; the oil film being expelled may not start to drip off.
