Never attempt any unauthorized modifications of the
hydraulic systems.
Whenever changing to another type of hydraulic
operating fluid, be sure to thoroughly flush out the
interior of the circuit. Never mix hydraulic operating
fluids of different types. Continued use creates the
risk of malfunction of, and damage to, the equipment.
Allowing the hydraulic operating fluid level in the tank
to become too low creates the risk of malfunction
and breakdown.
Always check hydraulic devices for looseness of
internal components that may have occurred during
transport and check to make sure that all
components are fitted securely.
Wipe up any hydraulic operating fluid that gets on
the product or floor. Failure to do so creates the risk
of personal injury due to the product slipping out of
your hand and falling, and due to someone slipping
on the fluid left on the floor.
Valve, pump and motor casing can become very hot
during operation. Do not touch them.
Never climb onto, strike, tip over, or apply excessive
force to a product. Doing so creates the risk of
malfunction, damage, fluid leaks, etc.
Never allow cutting oil, grinding oil, clippings, water
or other similar matter to get on or in hydraulic
devices.
Make sure installation holes and surfaces are clean.
Insufficient bolt tightening torque can allow fluid
leaks.
Always make sure to release all residual pressure
before starting disassembly work. Performing
disassembly work without releasing residual
pressure creates the risk of accident due to spurting
fluid, actuator free running, or dropping, and also
creates the risk of malfunction and breakdown.
For optimum performance, do not expose equipment
to temperature of 65 °C (150 °F) or higher.
If the system will not be operated for long periods, be
sure to take proper anti-rust measures.
Not operating the system for long periods without
taking anti-rust measures creates the risk of
malfunction and breakdown due to rust.
Be sure to flush the system before using it again
after long periods of non-use. Failure to flush out
rust inhibitors creates the risk of malfunction and
breakdown.
Seals may need to be replaced before using a
product for the first time after long storage.
