SAFETY NOTICE
Perform your company’s Lockout/Tagout
procedure. If your company does not have a
Lockout/Tagout procedure, follow OSHA
1910.147 and 1910.146 Confined Space as
appropriate.
3.1.1 Hydraulic Oil Level
• Daily Checks -
The oil level is checked by the operator or
skilled service personnel.
NOTE
Check hydraulic oil level during start-up
when the oil temperature is still cold.
Check the hydraulic oil level with all hydraulic cylinders in their
fully RETRACTED position.
• 3.1.1.1 Temperature / Level Sight Gauge
The gauge contains a thermometer which indicates the
temperature of the hydraulic oil in the reservoir. The reservoir
could have one of two gauges. The first type (Figure 37 ) is
distinguished by the word “LOW” below the sight glass. The
second type ( Figure 38 ) does not have the word “LOW” on the
gauge.
The hydraulic oil must be checked with all the hydraulic
cylinders in the fully RETRACTED position.
On a reservoir with a temperature/level sight gauge option
( Figure 37), oil level at 60 - 70°F should be at the black line in
the center of the green zone (Item 1). Oil should not be above
the “Max Fill Hot” line (Figure 37, Item 2) when the system
is at operating temperature. If there is too much oil in the
reservoir (above the “Max Fill Hot” line), there is a possibility
of the oil coming out of the breather at the top of the hydraulic
reservoir. Do not operate the system with oil below the “low”
line ( Figure 37 , Item 3) or damage to the system may result.
CAUTION
Do not operate the hydraulic system with oil
below the “low” line on the temperature/level
sight gauge.
Damage to the system may result.
