Refer to Figure A on page 4 for referenced items. 1 Connect air hose. 2 Each day, before you begin operation, go through the following checklist: 2.1 Make sure that the compressed air supply is at the proper pressure and that the lubricator is up to the full mark. (Use Jarvis Air Mist Lubricator Oil; if using a conventional air mist lubricator: set the feed rate at 8-10 drops per minute; if using a micro fog air mist lubricator*: set the feed rate at 100 drops per minute). *Almost all air mist lubricators are micro fog air mist lubricators. 2.2 Make sure the trigger lever is working correctly. Depress the lever (item 28) and the arms should open. Release the lever and the arms should close. If the tool malfunctions, remove it from service and report the problem to your supervisor immediately. 2.2.1 Depressing the lever (item 28) fully should should engage the latch (item 32) and lock the arms in the open position. Release the arms by sliding the latch (item 32) forward, toward the arms, and the lever (item 28) should disengage, allowing the arms to close. 2.3 Make sure that the BRE -1 or BRE -2 moves freely on the balancer. 3 Making the Seal: 3.1 Slide ring seal onto minor and major arms (items 16, 17, 21 and 25) so that the seal sets into the groove of each arm. Note: The model BRE -1 or BRE -2 must be deactivated with the minor and major arms in the close position when sliding on ring seals. Refer to Figure 1 on page 6 as a guide. 3.2 Depress lever (item 28) to open the ring. 3.2.1 For easier operation, depress lever (item 28) fully to engage the latch (item 32) and lock the minor and major arms in the open position. 3.3 Place expanded ring seal over colon/intestine at desired location.
3.4 Release the latch (if in locked position) and lever, and remove the BRE -1 or BRE -2. Figure 1 Bung Ring Seal Installation Bung Ring Seal maintenance instructions page 6 of 8 in the open position.
