Checking For High Pressure Leaks; Accumulator Safety - MASSEY FERGUSON 9186 Service Manual

Checking for High Pressure Leaks

FIG. 24: Fluid leaking from the hydraulic system or the
fuel injection system under high pressure can be very
hard to see. The fluid can go into the skin causing serious
injury.
Fluid injected into the skin must be surgically removed
within a few hours. If not removed immediately, serious
infection or reaction can develop. Go immediately to a
doctor who knows about this type of injury.
FIG. 25: Use a piece of cardboard or wood to search for
possible leaks. Do not use your bare hand. Wear leather
gloves for hand protection and safety goggles for eye
protection.
Relieve all pressure before loosening any hydraulic lines.
Relieve the pressure by lowering raised equipment,
shutting off accumulator valve, if equipped, and shutting
off the engine. Tighten all connections securely before
applying pressure.

Accumulator Safety

m
DANGER: Charging
accumulator must be performed by an
authorized dealer only.
FIG. 26: The accumulator (1) is charged with dry
nitrogen gas. Use only dry nitrogen when charging the
accumulator. Do not use air or oxygen or an explosion will
occur.
Nitrogen gas when released can cause localized freezing.
Always wear protective gloves and glasses when
handling nitrogen.
Do not drop the accumulator. A charged accumulator
contains nitrogen under pressure. If the shut off valve
breaks away from the accumulator, the escaping nitrogen
will propel the accumulator at a high rate of speed.
