Page 5: Chapter 1 - Safety
CHAPTER 1 – SAFETY 1.1 Foreword The following set of rules has been drawn up to ensure the application of precautionary principles that help to preserve the safety of persons and property when the machine is in use. Any failure to comply with these rules can have serious repercussions (bodily injury, etc.), and can even be fatal, so we must draw your attention to the fact that all persons involved in the use, maintenance, storage or custody of the machine covered by the present manual must be familiar with these rules. -
Page 6: General Safety Instructions
1.3 General safety instructions • The operator and the working environment To avoid all risks of accident or injury, it is essential to wear: - Sturdy, non-flammable clothing that is suitably close-fitting - Strong, non-slip gloves - Safety shoes - Protective eyewear - Safety helmet - All other equipment necessary on the site or when using the machine In the case of use of ear defenders, the safety instructions in force on the site must be complied with at all times. - Page 7 • The operator and the machine Before putting the machine into service each time, check that its condition and its operation are in compliance with the instructions. In particular, make sure that the controls are free and in good working order, and that they are in the “stop” or “neutral” position. Never make any modifications that could affect correct operation of the control systems.
- Page 8 • Using and handling fuel and oil It is essential to stop the engine and set the control to the stop position before carrying out any work involving fuel (filling up, checking the level, draining, etc.). Always keep suitable extinguishers ready for use in all areas where fuel is handled (storage, filling up, etc.). Always store fuel and oil in separate cans specially designed for the purpose and bearing the labels required by regulations.
- Page 9 • Tools to be used on the machine Use only the types of tools intended for normal use of the machine. Measure the speed of all rotating tools at regular intervals. Never use tools at speeds greater than the maximum speed for which they have been designed and approved. Never use damaged tools or tools that have reached their maximum level of wear.

Page 12: Chapter 2 - Description Of The Machine
Light and compact, the machine is easily carried and manipulated by a single operator. Ease of use and low vibration (in spite of its robustness and high power) make the MIW.3 the ideal choice for work on railway sites. The MIW.3 portable power wrench is powered by an air-cooled 2-stroke engine with a centrifugal clutch, an all-position membrane carburettor and built-in fuel pump, and electronically-controlled magneto ignition. - Page 13 2.2 General view Designation Rear hand protector Rear handle Air filter cover Tubular front handle Exhaust silencer with exhaust shield 1” (25.4 mm) square drive Impact device Rotation speed reducer Oil drain-refill plug Oil level indicator Front handle Reverse lever Accelerator trigger lock Starter handle Air filter cover screw...

Page 16: Chapter 3 - Installation - Utilisation
CHAPTER 3 – INSTALLATION – UTILISATION 3.1 Fitting the socket The operations involved in fitting and removing the socket must be performed with the engine stopped. When changing a socket, never replace the cylindrical pin by a protruding fixing object (nail, metal wire, etc.) which could trap and drag the operator’s clothing and cause injury. -
Page 17: Filling With Fuel
only use good-quality engine oil intended for air-cooled two-stroke engines. It is preferable to use STIHL oil for two-stroke engines, which is • Engine oil specially made for STIHL engines and guarantees long engine life. Do not use oil intended for water-cooled engines, nor oil for 4-stroke engines. For machines with exhaust catalysers, prepare the mixture only with STIHL 2-stroke engine oil at a ratio of 1:50. -
Page 18: Inspecting The Machine
• Opening the cap Take hold of the folding handle and raise it to the vertical position (Fig.1). Fig.1 Fig.2 Turn the cap fully anticlockwise (approximately ¼ of a turn) (Fig.2). The mark on the tank cap and the “open position” symbol marked on the machine must coincide. Remove the tank filler cap (Fig.3). -
Page 19: Chapter 4 - Utilisation
• Checking the fuel level (this check is done with the engine stopped) - Check the fuel level and top up if necessary ( : be sure to refer to 1.3 “General safety instructions” / “Utilisation and handling of fuel” and 3.2.2 “Filling with fuel”). - Page 20 4.2 Using the machine Positions of the universal lever = Stop engine – ignition off. = Normal working position – the engine is running or is able to start. To move the universal lever from the position to , push simultaneously the accelerator trigger lock and the accelerator trigger.
- Page 21 Accelerate slightly for a few moments to allow the engine to warm up. To facilitate engine starting and avoid the risk of accidents, the lower part of the machine must be resting on the ground. If appropriate, make the adjustment for winter use (see “winter use”). Push down the button to open the If the engine does not start at the first attempt, the universal control...
- Page 22 Never do tightening or releasing work before the engine is warm Tightening operation Bring the reverser lever to the tightening position (to the right). Place the machine in position on the bolt or lag screw, holding it vertically in both hands, one on the handle with the accelerator lever and the other on the tubular front handle (utilisation in vertical position).

Page 25: Chapter 5: Servicing And Maintenance
CHAPTER 5: SERVICING AND MAINTENANCE 5.1 Servicing This equipment must only be serviced and repaired by persons with the required training, skills and tools. Equipment servicing and repair must only be carried out by competent persons with good general mechanical knowledge. Stop the engine before any servicing work (leave the control in the Stop position) and wait for it to cool down. -
Page 26: Carburettor
5.1.4 Carburettor When the machine leaves the factory, the carburettor is optimally adjusted according to the barometric and meteorological conditions prevailing on the site of the production plant. Apart from routine maintenance during use, it is advisable for carburettor repairs or adjustments to be carried out by personnel from the GEISMAR / STIHL sales or repair network. - Page 27 If the idling speed is irregular or acceleration is unsatisfactory: the idling adjustment is too weak. Turn the idling mixture screw anticlockwise until the engine runs evenly and acceleration is normal. After each adjustment of the idling mixture screw, the idling speed stop screw LA generally also requires adjustment. Correcting the carburettor adjustment for working at high altitude if the engine does not run satisfactorily Turn the high speed mixture screw clockwise (to weaken the mixture) to the limit against the stop.
