WARNING
Do NOT disconnect or remove any hydraulic system line or fitting unless hydraulic system pressure has
been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid under pres-
sure can penetrate the skin, causing serious injury.
At operating temperature hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any
hydraulics. Failure to do so could result in injury.
CAUTION
Cap all hoses and openings to prevent fluid loss and contamination of oil system.
NOTE
Tag all hoses to aid in installation.
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.
Right and left check valves and lift cylinders are replaced the same way. Left-side check valve and lift
cylinder is shown.
