assembly, refer to Figure 13.

lever down until linkage comes to its mechanical stop.
2. Adjust stop nut until the top edge of the manual close
lever just contacts the spacer.

assembly must be properly adjusted to operate properly,
refer to Figure 14.

Motor
CAUTION
This type of motor should NEVER be energized while
disconnected from gear reduction unit. Uncontrolled
motor speed will result when operated without load,
excessive speed will damage motor.
A universal series-type motor is used to charge the closing
springs. The motor is energized from either a 240- or
120-Vac auxiliary power source, through a fused pullout
switch. The motor has permanently lubricated, sealed ball-
bearings that require no service. Periodically check motor
brushes for wear or burning, replace as required.
ote:N Brush replacement kits are available for both the
240- Vac and 120-Vac motors. The kit consists of two
brushes and two brush caps.
Motor replacement
The universal drive motor must be replaced, as an
assembly, if it become damaged or worn. To replace the
motor proceed as follows, refer to Figure 5:

within operating linkage personal injury couldresult.
1. Remove fused pullout switch to de-energize AC power
source to operator mechanism.
2. Make sure recloser contacts are open; manually
operate mechanism until contact position indicator
reads OPEN and closing spring status indicator reads
SPRINGS DISCHARGED.
3. Cut motor leads, close to old motor.
4. Remove hardware securing motor and carefully remove
from operator assembly.
5. Position replacement motor into operator assembly,
engage motor shaft into coupling, secure with hardware
removed. Apply Loctite #242 (blue) to screw threads
prior to assembly.

motor leads to old motor leads.
