The hydraulic-oil filter gauge should only be read
by qualified trained maintenance personnel. An
accurate reading requires very special conditions
and should not be attempted by operators.
T
HYDRAULIC OIL LEVEL
The hydraulic-oil level gauge (1) is on the side of
the hydraulic oil tank. It shows the actual level of
oil inside the tank. Read it only when the booms
are completely down and completely retracted.
Otherwise, the lift and/or extend cylinders
become large reservoirs for hydraulic oil and the
oil level in the tank will be low. The oil level (2)
should be between the high mark (3) and low
mark (4).
T
HYDRAULIC OIL TEMPERATURE
The hydraulic-oil temperature gauge (1) is inside
the hydraulic-oil level gauge. It measures the
temperature of the oil in the tank (2). The
temperature should not exceed 200°F (93°C). If it
does, reduce your driving speed or stop the
TB120 to let the hydraulic oil cool.
T
TEMPERATURE
The TEMPERATURE gauge is located just
above the ground-control box. It shows the
temperature of the water-antifreeze mixture in
the engine block. The typical operating-
temperature range for a Continental engine is
180°F to 202°F (81°C to 94°C); for a Cummins
engine, 141
°F to 211°F (60°C - 100°C).
