Maintenance
Hydraulic System
Check Hydraulic Oil
The hydraulic motors and hydraulic cylinders use the
same hydraulic oil reservoir and hydraulic oil supply.
Take care when working with the
hydraulic system to ensure it is completely clean.
Never allow the hydraulic oil level to
fall too low. Pump damage will occur.
DO NOT use your hands on any
hydraulic hoses, ttings or system component when
checking for leaks. Serious personal injury can
result from an oil leak under high pressure. Oil can
be injected under the skin by high pressure. Protect
the eyes by wearing safety glasses.
Check the hydraulic reservoir oil level daily using the
sight gauge located on the right side of the paver (inside
hub above right rear tire). (Figure 5-15)
• DO NOT use unltered hydraulic oil.
• Check the hydraulic oil level using the sight gauge.
• Check the hydraulic oil level when the hydraulic oil
is at normal operating temperature for an accurate
reading.
• If the hydraulic oil level falls below the black line, add
more hydraulic oil.
Check the hydraulic oil level when the hydraulic oil
is at normal operating temperature for an accurate
reading.

DO NOT loosen or remove the
hydraulic oil strainer ll cap when the hydraulic oil
is hot. Always loosen the cap slowly to relieve any
pressure in the hydraulic oil reservoir.
DO NOT overll the hydraulic oil
reservoir.
Leeboy uses a leak-detection dye that
may turn the hydraulic oil a slight yellow tint.
Change Hydraulic Oil and Filter
Changing the hydraulic oil removes the accumulation
of dirt, water and mechanical wear particles from the
hydraulic oil system. Clean, ltered oil is critical to
optimize hydraulic system operation. The hydraulic oil
system holds approximately 41 gallons. Access the
hydraulic lter via the hopper access panel. (Figure
5-16)
Contaminated hydraulic oil can
shorten the expected service life of components in
the hydraulic system.
DO NOT drain the hydraulic oil when it
is hot. Hot hydraulic oil can cause serious personal
injury.
Protect your eyes by wearing
safety glasses when working on hydraulic system
components.
