GBFor a hydraulic power pack with gasoline engine, makesure that the storage location is properly ventilated.The SUPERTIRFOR wire rope must be entirely removedfrom the machine and stored on a reel.Before winding the wire rope on its reel, inspect the wirerope, clean it using a brush and lubricate it (seerecommendations in §11).The hoses should be stored in the most linear positionpossible, horizontally.9. SAFETY DEVICES9.1 SUPERTIRFOR TU16H and TU32H9.1.1 Safety device limiting overloads9.1.1.1 SUPERTIRFOR safety pinsAll the machine models are equipped with a system ofshear-type safety pins. In the event of an overload, one orseveral pins (depending on model) located on the forwardoperating lever will shear, making it impossible to continuethe movement. However, it is still possible to lower the loador release the effort by actuating the reverse operating lever.9.1.1.2 Hydraulic ramsThe rams are equipped with a pressure relief valve, factorycalibrated,to avoid overpressures in the ram in the forwardoperating mode.When one or several channels are used, if one of themachines exceeds the nominal load, without rupture of theSUPERTIRFOR safety pins, the complete installationstops.To correct this situation:- decrease the load, or- balance the load better on the various machines, or- release (or lower) the load by maneuvering, using therams (or the extending handles after removing the rams)the reverse operating levers of the SUPERTIRFORmachines.IMPORTANT: The valve will not allow you to detectan overload in reverse operation.9.1.2 Clutch release safety deviceThe TU16H and TU32H models are equipped with a “twohand”clutch release device requiring a deliberatemaneuver to disengage the machine (see chapter 5Releasing and engaging clutch).9.2 Hydraulic power packs9.2.1 “Deadman” device (only valid forhydraulic power pack with electric motor)A “deadman” device is provided with the hydraulic powerpacks. Operation of the device consists in shutting downthe electric motor of the hydraulic power pack when thepushbutton actuating the hydraulic power pack is released.9.2.2 Safety valveThe hydraulic power packs are equipped with a pressurerelease valve (overpressure safety), factory-calibrated, toavoid overpressures in the hydraulic power pack. If thevalve opens, it is no longer possible to lift a load. The loadremains stationary. However, the machine can still bemaneuvered to lower (or release) the load by maneuvering,using the ram (or the extending handle, after removing theram), the reverse operating lever.IMPORTANT: The valve will not allow you to detectan overload in reverse operation.9.2.3 Thermal protection probe (only valid forhydraulic power pack with electric motor)The electric motor of the hydraulic power pack is equippedwith a thermal probe. If the motor overheats, the motor isshut down. Allow the motor to cool before restarting it.If shutdown of the motor occurs again, better ventilation forthe motor must be provided.10. REPLACEMENT OF SUPERTIRFORSAFETY PINSIMPORTANT: It is prohibited to replace shearedpins with anything other than genuine SUPERTIRFORpins of the same model.NOTE: We recommend that you keep asufficient quantity of spare SUPERTIRFOR pins to avoidany extended work stoppage when using the machine.10.1 Standard precautionsBefore replacing pins, you must first:1) Ensure that there is no load on the machine.2) Shut down the hydraulic power pack and disconnect itfrom its power source.3) Remove the ram from the SUPERTIRFOR machine.10.2 Equipment requiredDesignation For TU16H For TU32H13 mm wrench Yes NoHub puller Yes NoPin drift Yes YesHammer Yes Yes10.3 TU16HFigure 20 on page B shows the location of theSUPERTIRFOR safety pins.To replace the pins, proceed as follows:1) Unscrew the hex head screw (figure 19, item 1, page B)using the 13 mm wrench and remove the washer.2) Remove the forward operating lever from its pin; this willrequire use of a hub puller.3) Remove the sheared SUPERTIRFOR pins using a pindrift.4) Clean the pin housing.5) Reinstall the forward operating lever on its swivel pin bylining up the half-housing of the pin with those of thelever (see figure 20, page B).6) Fully engage the new replacement SUPERTIRFORpins (located in the forward operation ram bearing, item22, figure 2, page 7) into their housing by tapping lightlywith the hammer.7) Fit the washer and tighten the screw using the 13 mmwrench.- 16 -
