[. . . ] 32 mm Constant-speed electronics with variable stroke rate, 4 stroke rate settings Keyless, for standard 1/2 blades < 92 dB (A) Blade clamp Noise (pressure) level Typical vibrational acceleration (weighted) < 5. 0 m/s2 under no load Orbital action Selectable The tool is offered in different versions for various mains voltages. Please refer to the information on the type plate for the nominal voltage and nominal current input of your tool. 10 Safety precautions When using electric tools, the following fundamental safety precautions must always be observed in order to avoid the risk of injury, electric shock and fire hazards. Please read and observe the instructions below before using the tool. 7. [. . . ] Accordingly, if necessary, have the tool repaired at a Hilti service centre or authorised Hilti repair workshop. Always wear protective gloves and suitable protective goggles when working as saw blades may break or splinter. It is safer than using your hand and it frees both hands to operate the tool. Form the habit of checking to see that keys and adjusting wrenches are removed from the tool before switching it on. Always ensure that the blade clamping mechanism is kept clean. c) Turn the blade clamp locking sleeve in a counterclockwise direction. Note: If the saw blade cannot be inserted into the blade clamp, turn the locking sleeve a little until the blade is in the correct clamping position and then release the locking sleeve. Removing the insert tool a) Unplug the supply cord from the electrical socket to prevent unintentional starting. The insert tool may be very hot after long periods of use. Preparation for use It is essential that the safety precautions printed in these operating instructions are read and observed. The supply voltage must correspond to the information on the type plate. If extension cords are used: Only extension cords of a type approved for the intended use and of adequate cross section may be used. Failure to observe this point may result in reduced performance of the tool and overheating of the cord. length for extension cords are: Mains voltage 100 V 230 V Conductor cross-section 1. 5 mm2 2. 5 mm2 20 m 40 m 50 m 100 m Sawing Setting the stroke rate The recommended stroke rate can be pre-selected by turning the stroke rate adjusting wheel to the desired setting. When the operating switch is pressed the saw will then run at the pre-selected stroke rate. The preselected stroke rate remains almost constant, even under load, thanks to the tool's built-in constant-speed electronics, which also prevent overheating of the machine when working with the pipe-cutting adaptor. The machine switches itself off automatically as soon as the motor is overloaded. The recommended stroke rate settings and information concerning the correct choice of saw blade can be found in the information supplied with these products and in the corresponding table of applications. Stroke rate selection (1 = low stroke rate, 4 = high stroke rate) Material cut Recommended stroke rate Extension cables outdoors Only suitable approved and correspondingly marked cables may be used outdoors. Proceed logically and do not use the tool when your full concentration is not on the job. Operation Inserting the blade Use only blades with a standard 1/2 shank connection end. a) Unplug the supply cord from the mains socket to prevent unintentional starting. 12 Wood 4 Wood with embedded nails 4 Drywall, interior finishing 3 Plastic 1­3 Steel 1­3 Non-ferrous metals 2­3 Aluminium 2­3 Stainless steel 1 The above settings are recommendations intended to ensure optimum cutting performance. The optimum setting may differ from these recommendations depending on the saw blade used, the mains supply voltage and the sawing technique employed. Please observe the instructions on care and maintenance of your insert tools given in the following section. [. . . ] Should you wish to return the electric tool yourself to a disposal facility for recycling, proceed as follows: Dismantle the tool as far as possible without the need for special tools. Use absorbent paper to wipe lubricated parts clean and to collect the grease that runs out (total quantity approx. On no account should grease be allowed to enter the waste water system or to find its way into the ground. The individual parts should be separated as follows: Part / assembly Toolbox Outer casing Gear housing Grip Electronics module and switch Fan Motor (rotor and stator) Supply cord Gearing parts Screws, small parts Main material Plastic Plastic / elastomer Magnesium alloy Plastic Various Plastic Steel and copper Copper, elastomer sheath Steel Steel Recycling Plastic Plastic Scrap metal Plastic Electronics scrap Plastic Scrap metal Scrap metal Scrap metal Scrap metal Troubleshooting Symptom The tool doesn't start Possible cause Fault in the electric power supply Defective supply cord or plug Switch defective Tool doesn't produce full power Cross-section of the extension cord is inadequate Stroke rate regulator set to "low" Control switch is not pressed fully Function switch not set to orbital action Locking sleeve not turned as far as it will go Possible solution Plug in another electric tool and check whether it starts Have it checked by an electrical specialist and replace if necessary Have it checked by an electrical specialist and replace if necessary Use an extension cord of adequate crosssectional area.
