TQ Pro Expert PROTRJA20T Truck Jack Air/Actuated Bleed, PROTRJA20T Operating instructions

Hello! I've reviewed the bleed instructions for the TQB PROTRAJ20T Truck Jack. This document explains how to remove air from the hydraulic system, involving steps like removing springs, refilling oil, and manipulating the control knob. I'm ready to answer any questions you might have regarding the proper bleeding procedure or operation of the jack.
What are the symptoms of air in the system of a TQPro PROTRAJ20T Air/Hydraulic Truck Jack?

What type of hydraulic oil is recommended for TQPro Truck Jacks?

What should I do if the jack continues to show symptoms after bleeding?

when applying force to the load point.

1. With a leveraging tool Remove the 3 return springs from the Spring Saddle

and remove the Spring Saddle to reveal the Filler Bung.

2. Remove the filler bung and if required, refill with ISO68 Grade Hydraulic Oil

until the oil is lapping the bottom of the filler hole. Replace the Filler Bung,

Spring Saddle & Return Springs.

3. Connect the air supply line to the Raise/Lower Control valve at the top of the

handle assembly.

4. Turn the Raise/Lower control knob to the raise position and hold until the ram

reaches full extension.

5. Turn the Raise/Lower control knob to the lowering position and hold until the

ram is fully retracted.

6. Repeat steps 1 to 2 checking the oil level and topping up if required.

7. Repeat steps 3 to 5 checking oil level at step 5 until the rams extend smoothly

to full extension.

At this point the Air Motor Pump and Lift Ram should be free of air and the Jack

ready for operation. If the jack continues to show the symptoms as above repeat

steps 1 to 7 or please refer to a Qualified Hydraulic Technician.

*These TQPro Truck Jacks use ISO68 Grade Hydraulic Oil for the correct operation and compatibility with the seals used in their

construction.

The usual fault symptoms of a TQPro PROTRAJ20T Air/Hydraulic Truck Jack with air in the system are as follows.

- Air Motor Pump runs but no movement in the Lift ram.

- Lift Ram will only partially extend then air motor runs on.
