LUBRICATION

Under normal service conditions the motor, gearing,

bearings, and parts are all pre-lubricated and should

not require periodic maintenance. If for any reason the

unit is disassembled in the field, all oilite bushings

should be resaturated with an SAE-10, non-detergent

oil and all gearing heavily coated with Amoco Rykon

Premium Grease #2 or equivalent grease. Care should

be taken to ensure that no foreign material is allowed

to become combined with the grease in the gear train,

which will cause premature failure.  Keep gearbox

clean and dry.

DRAG BRAKE ADJUSTMENT

The drag brake serves two functions: a) to prevent

actuator from backdriving at maximum rated torque;

and b) to allow the motor shaft to slip when

handcranking and the output shaft load is in excess of

rated torque.
The drag brake was factory set and should not need

readjustment.  If it does need adjustment:
1. Apply an overhung load, equal to the maximum

torque rating to the output shaft.

2. Loosen drag brake jam nut until the motor shaft

starts to backdrive.

3. Tighten the drag brake jam nut just enough to

prevent backdriving.

4. While handcranking against the load, increase the

load until motor backdriving occurs.

Maintenance

TORQUE LIMIT SWITCH ALIGNMENT

The torque limit switches are factory set and field

adjustment is not advised unless proper test equip-

ment is available. If adjustment must be done, use the

following procedure:
1. Load the output shaft with a known load which

matches the torque rating of the actuator in an

opposing direction for the switch being adjusted.

2. Apply power to the motor and run the actuator to

drive the opposing load.

3. Increase the load by 5% to 10% and adjust the set

screw (140C) to trip the torque switch.

4. Remove the 5% to 10% increase of load and the

switch should reset.

5. Load the actuator in the opposite direction and set

the other switch in the same manner.

NOTE: When looking at the torque limit switch

assembly as it is mounted in the actuator, the switch

on the top of the assembly controls the CW torque

and the switch on the bottom controls the CCW

torque. The torque should be set near equal for both

directions.
When the actuator is driven into a torque condition

in the CW direction (looking at the output shaft), the

handcrank handle will move slightly outward. For

CCW direction the handle will pull slightly inward.
