Troubleshooting

Pump

The pump is operated by a control rocker switch located on the control panel. When the pump is
engaged, the switch turns to green.

Three conditions must be met for the pump to engage and for the rocker switch to turn green:

Engine speed must be lower than 900

rpm

Emergency S

TOP

button (red) pulled out

Engine speed is verified by the transmission ECU.

If the pump does not engage when the pump rocker switch is turned on, it may be related to a voltage
supply problem in the pump circuitry.

There is a pump test that can help resolve pump-related problems. For more information on that or
for advanced troubleshooting, please call Labrie

Plus

.

Prior to conducting a pump test, ensure that all these conditions are met:

Parking brake is applied

Engine is running (at idle speed)

Transmission is in “Neutral”

Emergency S

TOP

button(s) is pulled out

Pump (

PTO

) switch is ON

N

OTE

:

Neither the engine throttle nor the transmission not being in Neutral will affect pump
operation once the pump is engaged.

Pump Cavitation

Cavitation is defined as the formation of air pockets in a moving fluid. Air in the hydraulic oil causes
excessive wear and noise. Make sure to prime the pump properly after replacement or after flushing
the hydraulic system (refer to “Priming a New Pump” on page 80). When the pump is properly
primed, cavitation disappears after a short period of time because air is returning to the hydraulic
tank.

If the pump is still generating unusual noise after performing the pump priming procedure, then you
will have to bleed the hydraulic system.

To do so:

1.

Apply all safety measures to ensure safety around the vehicle at all times.

2.

Connect a 0–4000

psi gauge to the main valve to ensure that no pressure has built up in the

system.

3.

Apply the parking brake and start the engine.

4.

Engage the hydraulic pump (

PTO

switch “ON”).

5.

Place a pan or a bucket under the plug located on the output section of the main control valve and
slowly loosen the plug.

A mixture of oil and air will come out. Keep bleeding the oil until the pump noise stops.
