Page 7 of 21 Installation & Adjustment Procedures 1.7. Perpendicular to base installations 1.7.1. Attach the ground support saddle to the base mounting bracket. 1.7.2. Slide the pipe through the support saddle and pipe collars on both sides. 1.8. In the open position install the ground blade with the tapered end of the blade tip toward the jaw. Loosely attach the blade clamps on the pipe.

Carefully, lift the blade manually by hand confirming the blade tip is centered in the jaw (Figure 5) and the leading tapered edge is vertically in line with the jaw opening. If correct tighten the blade clamps and any loose hardware on the jaw mounting, proceed to the next phase until all are complete.

The weight of the vertical operating pipe should be supported by pipe collar by maintaining the 1/4”-3/8” gap. 4.2.2.2. When the switch is properly adjusted the operator handle should hang freely in both the open and closed positions to permit the use of the customer supplied padlock.

Recommended Inspection Maintenance Recommended Inspection Maintenance The ESD63 has been designed to operate with minimal maintenance. Periodic inspection is important for satisfactory operation. Frequency of inspection and maintenance depends on the installation site, weather and atmospheric conditions, experience of operating personnel and special operation requirements.
Page 16 of 21 Recommended Inspection Maintenance Patrolling Inspection (6 Months) The patrolling inspection is a largely visual inspection on an energized unit in service. The frequency of the inspection is determined by the local conditions and policies of the owner of the equipment. Refer to Table 2 for recommended inspection items.
