Confirme siempre con la documentaci\u00f3n de su unidad.<\/p>\n<h4>\u00bfY si la unidad tiene fugas por el respiradero?<\/h4>\n<p>Una bater\u00eda baja y una caja pesada pueden crear picos de presi\u00f3n durante el descenso, forzando la salida de aceite de un respiradero sucio. Cargue la bater\u00eda y limpie o sustituya el respiradero.<\/p>\n<h4>\u00bfPor qu\u00e9 oigo chasquidos pero no movimiento?<\/h4>\n<p>El solenoide puede activarse pero el motor ve baja tensi\u00f3n, o el carrete de la v\u00e1lvula no est\u00e1 cambiando. Realice una prueba de carga de la bater\u00eda, verifique la conexi\u00f3n a tierra y compruebe el magnetismo de la bobina.<\/p>\n<h4>\u00bfPuedo bajar temporalmente una cama atascada?<\/h4>\n<p>S\u00ed. Intercambie las bobinas arriba\/abajo en el colector para mover la cama, luego restaure y reemplace la bobina defectuosa.<\/p>\n<h4>\u00bfCu\u00e1ndo debo llamar a un profesional?<\/h4>\n<p>Si persisten las fugas despu\u00e9s de sustituir las juntas, si la bomba no genera presi\u00f3n a pesar de las comprobaciones el\u00e9ctricas o si carece de las herramientas necesarias para vaciarla, desmontarla y comprobarla de forma segura.<\/p>","protected":false},"excerpt":{"rendered":"<p>What is a Dump Trailer Hydraulic Pump?
