HRT/TRT 110 Brake Booster Installation<br />
The brake booster is shipped empty. It must be filled with oil and the air purged<br />
from the system before operating.<br />
The brake booster(s) are installed on the back of the rear cabinet door as shown.<br />
Mount the brake booster(s) by opening the rear cabinet door, clipping them to the<br />
top of the door, then shutting the rear cabinet door.<br />
Set-up<br />
Fill the reservoir by removing the plug (square bolt) and adding Mobil DTE 25. The<br />
oil should be added until it is 1/4” to 1/2” below the reservoir cap.<br />
Turn the pressure regulator down (turn adjusting knob counter clock-wise) so no<br />
air pressure enters the system. Install an air supply to the input side of the regulator.<br />
Loosen hex-head bolt on top of HRT/TRT unit. Slowly turn pressure up on the<br />
regulator until the gauge shows 5 psi. Hydraulic fluid flows through the system and<br />
exits through the loose bolt on the HRT/TRT body. Tighten the hex-head bolt once<br />
a steady flow of oil flows by the bolt.<br />
Refill the oil reservoir, it should be 1/4”<br />
to 1/2” below the reservoir cap.<br />
Pressure Adjustment<br />
Set the air pressure for the HRT/TRT<br />
brake booster between 35 and 40psi.<br />
Turning the knob clockwise increases<br />
the pressure, turning it counter-clock<br />
wise decreases the pressure. It may<br />
be necessary to pull up on the knob,<br />
before adjusting, to unlock it. Press<br />
the adjusting knob down once the<br />
pressure is set to lock the adjusting<br />
knob. Warning: Setting a pressure<br />
above the recommendation may damage<br />
the brake.<br />

Oil Level<br />
Check the brake booster oil level before using. The oil level should be 1/4” to 1/2”<br />
below the reservoir cap. If necessary, add oil by removing the plug (square bolt), at<br />
the top of the reservoir and filling with Mobil DTE25.<br />
