Water Cooling Supply ConnectionsIf the heat exchanger is installed where there is a chance of freezing on shutdown, the water circuit should be completely drained or the correct antifreeze solution should be added.Electric Motors

Periodically inspect the electric motors for dirt, friction, or vibration. Dust may be blown from inaccessible locations using air. Grease or oil can be wiped up using a petroleum solvent. The main electric motor is equipped with double-shield ball bearings, having sufficient grease to last indefinitely. When the motor is used constantly in a dirty, wet, or corrosive atmosphere, it is advisable to add a quarter ounce of grease per bearing every three months. Use a good quality bearing lubricant grease such as Cat 2S-3230 or equivalent.Other Operations
Oil Reservoir
Illustration 36 g02545477
The oil level Sight Gauge on the flow port panel of the test stand should be checked daily. Add oil when necessary to keep the level well within the Sight Gauge.
To avoid damage to the pumps, do not operate the test center when oil cannot be seen in the Sight Level Gauge.
The temperature of the oil in the test stand is indicated by the Temperature Gauge located at the bottom of the instrument panel. If the temperature reaches the 62.7° C (145° F) (approximate), allow the test stand to operate for a short while without performing any work until the heat exchanger has cooled the system. The circulation pump system is used to heat the oil. Pulling ON the RESERVOIR HTR switch will start the circulation pump and activate the heater elements. The heating system is thermostatically controlled and will cycle automatically to maintain a minimum oil temperature of 43.3° C (110° F) in the reservoir. It is good practice when not using the machine to cap all ports and turn all valves, controls, and switches to their OFF or CLOSED positions.Flow Meters
