The most importantthing to keep in mind whenusing this piece of equipmentis to ascertain that the piecebeing worked on is properlyblocked. If not, it is verypossible that the piece willcrack or break under the loador slip out and cause injury tothe operator. Remember theload capacity is 50 tons, that’sa lot of force.Crush injuryHigha) Ensure a clean work area.b) Block up/support the piece beingworked on in such a manner as to avoiddamaging the piece or having it get“spit out” from the pressure applied.c) Use the appropriate personal safetyequipment for the task. (protectiveeyewear, footwear)d) Make sure all safety guards and coversare in place.e) Clear the area of people before starting.f) Align the working piece with thecylinder before using.g) Maintain slack in the winch cable afteradjusting the table height, and makesure all the table pins are in positionand secure.h) Lock the cylinder carriage beforeusing.i) Do not exert excessive force whenusing the press, if it feels like it’s goingto break it probably will.Safetyglasses orFace shield,gloves,Safety bootsDailyPage 8 of 34
