WARNING:
• Stop the engine. Move the control levers back and
forth, and right and left several times to release
the remaining pressure in the hydraulic line.
• Before connecting hoses between the boom cylin-
der and the machine, gradually loosen bolts secur-
ing the covers to the ends of the hydraulic piping
on the machine to release the trapped oil pressure
in the piping.
1. Gradually loosen bolts securing the covers to the ends
of the hydraulic piping on the machine to release the
trapped oil pressure in the piping. Then, remove the cov-
ers.

boom cylinders and the machine.
