Testing Hydraulic Oil
It is recommended to have hydraulic oil tested and analyzed by a lab to prevent hydraulic system or
pump failures. This will also optimize the oil change frequency. Apply the following procedure to take
oil samples on Labrie vehicles.

The procedure may differ from other laboratories sample kits.
Hydraulic Oil Sample Preparation
Before taking hydraulic oil samples:
1.
Apply all safety measures to ensure safety around the vehicle at all times.
2.
Start the engine and engage the hydraulic pump.
3.
Raise the body.
4.
Install the body safety prop and lower the body onto it.
5.
Disengage the pump and turn OFF the engine.
6.
Locate the oil sample coupler along the right-hand side chassis frame rail. It is located behind the
filter cover (see Figure 4
1).

7.
Remove the cap from the sample coupler and clean the coupler with a clean rag.
8.
Push on the coupler spring ball (see Figure 4
2) using a small tip to purge oil before taking a
sample. The residual pressure in the system will push the oil out of the coupler. Use a small
container to recuperate the oil that will come out. Let the oil leak for a few seconds (about half a
cup). In this operation, the pump must be engaged.
Caution!
Highly contaminated hydraulic fluid must be changed promptly to avoid any damage in
the hydraulic system.
