When testing and adjusting the transmission and power train, move the
machine to an area clear of obstructions, with safe exhaust ventilation
for the exhausts. Sudden movement of the machine or release of oil
under pressure can cause injury to persons on or near the machine. To
prevent possible injury, do the procedure that follows before testing and
adjusting the transmission and power train.

Personal injury can result from spring force released when removing
cap screws.
Internal spring force will be released when cylinder assembly cap screws
are removed causing injury.
Always restrain cover as cap screws are loosened.
Follow the established procedure in the Service Manual to service these
parts.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the machine. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Dispose of all fluids according to local regulations and mandates.
Before you begin the test, refer to Troubleshooting, "Machine Preparation forTroubleshooting".

Initial Pressures - Test and AdjustSMCS - 3030-025-PX ; 3030-081-PX
When testing and adjusting the transmission and power train, move the
machine to an area clear of obstructions, with safe exhaust ventilation
for the exhausts. Sudden movement of the machine or release of oil
under pressure can cause injury to persons on or near the machine. To
prevent possible injury, do the procedure that follows before testing and
adjusting the transmission and power train.
Personal injury can result from spring force released when removing
8/17/2019 Desarmado y Armado Componentes Transmision Motoniveladora Serie h
19/224
cap screws.
Internal spring force will be released when cylinder assembly cap screws
are removed causing injury.
Always restrain cover as cap screws are loosened.
Follow the established procedure in the Service Manual to service these
parts.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the machine. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Dispose of all fluids according to local regulations and mandates.
Note: This procedure should be followed when a transmission control valve is repaired by
replacing any of the springs in the individual clutch stations.
Before you begin the test, refer to Troubleshooting, "Machine Preparation for
Troubleshooting".

Para hacer pruebas y ajustes de la transmisión o del tren de fuerza,
mueva la máquina a una zona libre de obstrucciones y en la que se
puedan ventilar los gases de escape sin peligro. El movimiento repentino
de la máquina o la descarga de aceite bajo presión puede causar lesiones
al personal situado en la máquina o en sus alrededores. Para evitar
accidentes, haga el procedimiento siguiente antes de hacer pruebas y
ajustes de la transmisión o del tren de fuerza.
ATENCION Se debe tener cuidado para que no se derramen los fluidos al hacer la
inspección, el mantenimiento, las pruebas, los ajustes y las
reparaciones a la máquina. Tenga a mano los recipientes necesarios
para recoger el fluido antes de abrir cualquier compartimiento o
desarmar cualquier componente que contengan fluidos.
Descarte todos los fluidos de acuerdo a los reglamentos y mandatos
