Disassemble and Assemble
Raised Machine
Never position yourself or any part of your body
under a raised machine which is not correctly
supported. If the machine moves unexpectedly you
could become trapped and suffer serious injury or be
killed.
Lifting Equipment
You can be injured if you use incorrect or faulty lifting
equipment. You must identify the weight of the item to
be lifted then choose lifting equipment that is strong
enough and suitable for the job. Make sure that lifting
equipment is in good condition and complies with all
local regulations.
Hydraulic Pressure
Hydraulic fluid at system pressure can injure you.
Before connecting or removing any hydraulic hose,
residual hydraulic pressure trapped in the service
hose line must be vented. Make sure the hose
service line has been vented before connecting or
