Never stand near hydraulic hoses under pressure.
Recover all spilled oil after servicing the
hydraulics system.
Note that poor welding may result in serious
personal injury or fatality. If you are unsure,
contact a professional welding technician for
instructions.
Exercise extreme caution when undertaking any
kind of work with the machine's hydraulic
system. Wipe with clean paper or cloths. Place
parts on a clean surface (not directly on the work
bench) Rinse before assembly, for example with
a decreasing agent.
Never rinse the bearings with a high pressure
water supply! It is important to grease the
bearings after washing in order to remove any
water that has remained behind.
Never clean bearings directly with a high-
pressure water jet. Clean electrical components
by blowing them with air or by wiping them with
a slightly dampened cloth.
