2. Now, move the handle lock to the “locked” position. This sets
the handle facing away from the operator.
3. Move the directional switch in the opposite direction used in Part
I.
4. Operate the tool carefully to open or close the gate valve.
5. Stop the HH500 when the digital counter reaches the previously
noted counter value, slowing down as it nears the fully open/
closed position.
NOTE:
Be aware the torque will increase if you go over the
previously noted counter value because now the gate valve is
being over-torqued and could potentially break or bind the
valve.
6. Remove the HH500 from the gate valve.
