DO NOT open hydraulic lines or loosen hydraulic
fittings while the engine is running! Hydraulic fluid
under pressure can penetrate the skin, blind,
cause burns or create other potentially dangerous
hazards.
WARNING - HYDRAULIC SYSTEM HAZARD
During routine maintenance or removing material
blockage, you will be required to put your hand in the
concrete cylinders or near the shuttle tube. You are at
EXTREME RISK of injury or AMPUTATION if the
engine is running or if pressure is in the hydraulic
system.
Prior to performing any maintenance on the pump,
follow described lock out-tag out procedures. Stop the
engine by turning off the ignition switch and remove
the starter key. Place a “DO NOT OPERATE” tag
over the switch and disconnect the battery. The
pressure reading on the
accumulator pressure
gauge
MUST read
ZERO. ALWAYS make
sure the accumulator
circuit pressure reads
zero prior to performing any maintenance on the pump.
DANGER - AMPUTATION RISK
