Theory of Operations
Descriptions of the various operations, control buttons, and indicators that make up the control panel are
listed below.
OFF MODE:
• When the unit is connected to power, an alarm will sound indicating power-up, all LED’s will flash on and
off and then the ENGINE START light will be flashing.
• When the vehicle is started, the fluid and pressure from the vehicle should have reached the machine
and the ENGINE START light will go steady on and the gauge will indicate the pressure coming in from
the vehicle. It is now ready to begin a service if there is fluid in the clean fluid tank.
SERVICE MODES:
• Push DRAIN button to perform a drain pan service on vehicle. The unit will automatically route the
used fluid from the vehicle’s transmission into the unit’s waste tank until the transmission is empty and
the pressure drops.
Push CHANGE FLUID button to perform a fluid exchange. The unit will route the used fluid from the
vehicle’s transmission into the unit’s waste tank and supply an equal amount of new fluid from the unit’s
clean tank into the transmission. During the service the ENGINE START lights will be on steady. The
DRAIN and FILL lights may go on and off periodically as the unit controls the fluid level in the vehicle.
DRAIN MODE at the end of service:
• After service is complete, (COMPLETE light is on), if the transmission level needs to be lowered push
the DRAIN button. Fluid will drain only as long as the button is pressed, flow will stop when the button is
released.
FILL (TOP OFF) MODE at the end of service
• Push FILL button after service is complete (or COMPLETE light is on, see step below). Fluid will flow into
the vehicle’s transmission only as long as button is pushed
LOW CLEAN FLUID LIGHT:
• The light will be on when the clean fluid tank is empty down to the zero mark.
COMPLETE LIGHT:
• The COMPLETE light will turn on at end of service. The unit will automatically revert to bypass mode.
ENGINE START LIGHT:
•
The light will flash if the engine needs to be started or if fluid flow needs increased.
• The light will be on solid when the engine is running indicating good flow from the vehicle.
ENGINE STOP LIGHT:
•
The light will flash if the engine needs to be stopped/turned off.
• After the engine is stopped/turned off, the light will be on steady.
EMPTY WASTE LIGHT:
• A flashing empty waste LED after an exchange is complete or before one has began indicates that
there is fluid in the waste tank. If the EMPTY WASTE button is pushed at this time the unit will empty
the waste tank to the ‘zero’ line. Note: It is not necessary to empty the Waste Tank before perform-
ing an exchange. If beginning an exchange with fluid in the waste tank ensure that there is less fluid in
the clean tank than the remaining capacity of the waste tank. Failure to do so will result in Waste Tank
overflowing!
STOP SWITCH:
• Will turn off an alarm without stopping the machine when an alarm is sounding during the CHANGE
FLUID mode (when pushed only once).
• Will pause the service and revert the system to bypass mode and hold the fluid level memory when
pushed without the alarm sounding. Press the CHANGE FLUID button to resume service.
