Bobcat 853 lift arm drops

[conc2steel]

My lift arm no longer remains in the "up" position. It drops and I need to continually "lift" to keep it in place. Any ideas what is going on?

Download these test procedures and run thru them and they should tell you if it's the cylinder, spool or load check.
