Figure 1 -- Operation

.Pressing the bottom of the ROCKER SWITCH down will cause the ANVIL to move in a clockwise direction. This will commonly tighten the fastener.

“Breaking Loose” Fasteners

Note: This procedure is used when a fastener becomes “frozen”, typically due to corrosion. This procedure assumes that the threads are standard (clockwise to tighten, counter clockwise to loosen). If the threads are reversed, you must reverse the switch directions contained herein.

1.Spray silicon or another appropriate lubricant on the fastener and allow it to sit for 15-30 minutes.

.Rapidly press the ROCKER SWITCH (6) up and then down. This will cause the ANVIL (16) change direction rapidly and loosen the bolt.
