Hands, clothing or tools getting caught in the fan blades or transmission belts, can cause amputations, violent hemorrages and generate conditions of grave danger. For this reason avoid touching or approaching all rotating or moving parts.
  • Page 15 INTRODUCTION When hydraulic oil has been swallowed, avoid vomiting, but consult a doctor or go to a hospital. If an accident occurs, see a doctor familiar with this type of injury immediately. Any fluid penetrating the skin must be removed within few hours to avoid serious infections.
  • Page 16 INTRODUCTION Hoses and tubes Always replace hoses and tubes if the cone end or the end connections on the hose are damaged. When installing a new hose, loosely connect each end and make sure the hose takes up the correct position be- fore tightening the connections.
  • Page 17 INTRODUCTION Battery Batteries give off explosive gases. Never handle naked flames and unshielded light sources near batteries. (No smoking is addressed in next instruc- tion).

  • Page 18 INTRODUCTION Flammable liquids When handling flammable liquids: • Do not smoke. • Keep away from unshielded light sources and naked flames. Fuels often have a low flash point and are readily ignited. Never attempt to extinguish burning liquids with water. Use: •...
  • Page 19 INTRODUCTION Tires Before inflating the tires, always check the condition of rims and the outer condition of tires to find out the pres- ence of dents, cuts, tears of reinforcement plies or other faults. Before inflating a tire, make sure that there are no nearby persons, then position yourself at tread side.
  • Page 20 INTRODUCTION Waste disposal Improperly disposing of waste can threaten the environ- ment. Each country has its own Regulations on this subject. It is therefore advisable to prepare suitable containers to collect and store momentarily all solid and fluid materials that must not be scattered in the environment to avoid pollution.

    INTRODUCTION Torque Bolt types NOTICE: Use tools appropriate for the work to be done. Makeshift tools and procedures can create safety haz- ards. For loosening and tightening nuts and bolts, use the correct tools. Avoid bodily injury caused by slipping wrenches.
  • Page 22 INTRODUCTION Bolt tightening order When tightening two or more bolts, tighten them alternately, as shown, to ensure even tightening. SMIL13CEX0149EA A Equally tighten upper and lower alternately B Tighten diagonally C Tighten from center and diagonally 48017211 02/05/2016...
  • Page 23 INTRODUCTION Service recommendations for split flange 1. Be sure to clean and inspect sealing surfaces. Scratches/roughness cause leaks and seal wear. Unevenness causes seal extrusion. If defects cannot be polished out, replace the component. 2. Be sure to use only specified O-rings. Inspect O-rings for any damage.
  • Page 24 INTRODUCTION Nut and bolt lockings Lock plate NOTICE: Do not reuse lock plates. Do not try to bend the same point twice. Cotter pin NOTICE: Do not reuse cotter pins. Match the holes in the bolt and nut while tightening, not while loosening. Lock wire NOTICE: Apply wire to bolts in the bolt tightening direc- tion, not in the bolt-loosening direction.
  • Page 25 INTRODUCTION Piping joint Pipe thread connection/Union joint tighten- ing torque specifications Union joint Metal sealing faces (4) and (5) of adaptor (1) and hose (2) fit together to seal pressure oil. Union joints are used to join small-diameter lines. 1. Do not over tighten union nut (3). Excessive force will be applied to metal sealing surfaces (4) and (5), possibly cracking adaptor (1).
  • Page 26 INTRODUCTION O-ring seal joint O-ring (6) seats against the end face of adaptor (7) to seal pressure oil. O-ring procedures: 1. Be sure to replace O-ring (6) with a new one when reconnecting. 2. Before tightening union nut (9), confirm that O-ring (6) is seated correctly in O-ring groove (8).

See below for correct tightening torque of each type of low-pressure-hose clamp. T-bolt type band clamp: 4.4 N·m (3.25 lb ft) Worm gear type band clamp: 5.9 - 6.9 N·m (4.4 - 5.1 lb ft) SMIL13CEX0159AA A - T-Bolt Type SMIL13CEX0160AA...
  • Page 29 INTRODUCTION Connecting hose 1. When replacing hoses, be sure to use only genuine parts. Using hoses other than genuine hoses may cause oil leakage, hose rupture or separation of fitting, possibly resulting in a fire on the machine. 2. Do not install hoses kinked. Application of high oil pressure, vibration, or an impact to a kinked hose may result in oil leakage, hose rupture or separation of fit- ting.
