Adding Hydraulic Oil To
Hydraulic Oil Reservoir
The hydraulic reservoir oil level must be visible in the
sight gauge (Figure 7-23,1) to be at the correct level.
If the hydraulic oil level is below the sight gauge, the
correct, ltered hydraulic oil (see Specications in
Section 4) must be added to the hydraulic oil reservoir
until the oil level is shown to be full in the sight gauge.
Do not remove the hydraulic ller cap
from the reservoir when it is “HOT”. Hot hydraulic oil
can cause serious injury. Allow hydraulic oil to cool
down to a warm temperature.
1. Unscrew hydraulic oil tank ller cap (Figure 7-23,2).
Do not over ll the hydraulic oil
reservoir.
2. Add needed amount of new, ltered hydraulic oil
(see Specications in Section 4).
3. Keep the oil level of the hydraulic oil reservoir at the
correct level.
NOTE: An air space is designed into the hydraulic oil
reservoir and allows for oil expansion, at warm
temperatures. The hydraulic oil reservoir will
have a low pressure in it at system operating
temperatures.

Hydraulic System
General Information
The hydraulic motors and the hydraulic cylinders use
the same hydraulic oil reservoir and hydraulic oil supply.
Checking Hydraulic Oil Level
Check the hydraulic reservoir oil level, one time each
day, by looking at the sight gauge on the reservoir.
Check the oil level when the hydraulic oil is at “normal”
operating temperature only.
Do not loosen, or remove, the hydraulic
oil reservoir ller cap when the hydraulic oil is “HOT”.
always loosen the ller cap slowly to relieve any
pressure in the hydraulic oil reservoir.
Only loosen the ller cap when the oil
is at a “WARM” temperature.
The paver should be parked in a level
area before check hydraulic oil.
