WARNING
When starting the machine for the first time, be sure that all persons stand clear, in case a hose has not been
completely tightened.
This machine must remain stationary and switched off with the booms unfolded and supported while
installation or maintenance is conducted.
CAUTION
Hydraulic Safety
Hydraulics may be under pressure. Never attempt to open or work on a hydraulic system with the equipment
running. Care should always be taken when first opening a system that has previously been pressurized.
When disconnecting the hydraulic hoses or purging is required, be aware that the hydraulic oil may be
extremely hot and under high pressure. Caution must be exercised. Any work carried out on the hydraulic
system must be performed in accordance with the machine manufacturers's approved maintenance
instructions. Raven Industries recommends that appropriate protective equipment be worn at all times when
working on the hydraulic system. When installing AutoBoom hydraulics or performing diagnostics,
maintenance, or routine service, ensure precautions are taken to prevent any foreign material or
contaminants from being introduced in the machine's hydraulic system. Objects or materials that are able to
bypass the machine's hydraulic filtration system will adversely reduce performance and possibly damage the
AutoBoom hydraulic valves.
Electrical Safety
Do not reverse power leads. Doing so could cause severe damage to the equipment. Always make sure that
the power leads are connected to the correct polarity as marked. Ensure that the power cable is the last cable
to be connected.
