F660504 Force GROMMET (REMOTE ACCESSORY CABLE)

MANUAL CONTROL: The hand operated control lever, usually mounted on the steering column, provides a smooth modulated application of the BrakeSaver to apply any desirable retarding of the vehicle, up to engine rating. This controlled modulation of the BrakeSaver is especially desirable on slippery roads. Increasing or decreasing the BrakeSaver action is accomplished by moving the control lever. AUTOMATIC CONTROL: The mode selector switch must be in the AUTOMATIC MANUAL position for automatic control. In this mode the BrakeSaver will automatically be applied when the clutch is engaged and the operator takes his foot off of the accelerator pedal. The BrakeSaver will automatically shut off when the clutch is disengaged. It will engage again when the clutch is re-engaged. GAUGES: The BrakeSaver CONTROL AIR PRESSURE gauge indicates the pressure at the BrakeSaver control valve. Air pressure should not exceed 50 psi (345 kPa).If the indicator shows reduced or no pressure, stop the vehicle or operate at a reduced speed. Control vehicle stopping with proper downshifting and service brakes until proper repairs are made.The BrakeSaver oil temperature gauge indicator should register in the NORMAL (green) range. If the indicator moves to the red range, move the BrakeSaver manual control lever to the OFF position.Operate the vehicle with the service brakes only, or stop the vehicle and let the engine idle until the oil temperature registers in the NORMAL range. No special skills are required to operate a vehicle with a BrakeSaver. However, it requires the driver to watch the engine speed and the BrakeSaver oil temperature.For maximum BrakeSaver effectiveness, select the proper gearing to keep the engine RPM as close to the rated speed as possible.Manual operation adds modulation to the BrakeSaver control and allows the driver to match driving conditions to any load or hill. Do not control the vehicle speed with the accelerator whie the manual control is on.The BrakeSaver is not an emergency or quick stop brake.Allow a 2 second delay for full engagement and full disengagement.Use the service brakes for quick stops.To prevent unnecessary fuel consumption and possible heat buil-up, do not leave the BrakeSaver in operation when the engine is idling while parked. Place the control selector switch in MANUAL position, and the manual control lever in the OFF position. DRIVER OPERATIONAL CHECKS: There are two quick operational checks the driver can make to determine if the BrakeSaver is operating properly. Also, if the control valve spool is operating freely in the control.1. To check retarding horsepower: a. Place the transmission in neutral.b. Run the engine at high idle RPM.c. Engage the BrakeSaver fully.d. The engine speed should drop approximately 125 25 RPM.
The engine should not run against the BrakeSaver for more than 15 seconds. Allow 5 minutes between applications to prevent the cooling system from overheating.
2. To check control valve spool free movement: a. Start the engine and run it until the air system is at maximum pressure.b. Shut off the engine and engage the BrakeSaver before the air pressure drops below 70 psi (480 kPa).c. Disengage the BrakeSaver and listen for a "klunk" sound. This "klunk" sound is the control valve hitting the control valve end cover. This indicates that the control valve is free and the control springs are operating normally. Also, that the air is venting properly from the control valve.
