High Pressure Leaks; Accumulator Safety - MASSEY FERGUSON MF2200 Operator's Manual

1. Safety

1.4.3 High pressure leaks

WARNING: Hydraulic fluid under
pressure can penetrate the skin or
eyes.
Serious personal injury, blindness, or
death can occur.
Relieve the pressure from the system
or component before disconnecting
components. Wear personal
protective gear while working on the
machine or equipment. Use a piece of
cardboard to check for leaks. Never
use your hand.
Fluid that leaks from the hydraulic system or the
fuel injection system is high pressure and is not
easily seen. The fluid can go into the skin causing
injury.
Fluid that is injected into the skin must be
surgically removed immediately. If not removed
immediately, infection and reaction can occur. Go
immediately to a physician who knows about this
type of injury.
Use a piece of cardboard or wood to look for
possible leaks. Do not use your bare hand. Wear
leather gloves for hand protection and safety
goggles for eye protection.
Remove all pressure before you loosen hydraulic
lines. Lower equipment in the up position, close
the accumulator valve, and stop the engine.
Tighten all connections before you apply pressure.

explosion will occur.
Nitrogen gas, when released can cause freezing.
Always wear protective gloves and glasses when
around nitrogen.
Do not let the accumulator fall. A charged
accumulator contains pressurized nitrogen. If the
