DUAL SPEED JOG
Each LITHIUM SERIES Tool is equipped with a dual-speed gearbox. The gearbox has two modes:
In the event the gear selector does not engage, a JOG FORWARD or JOG REVERSE screen will be displayed. Press the
trigger briefly to synchronize the gears and re-engage the drive mechanism.
1. RUNDOWN MODE: The gearbox is set to run at a higher speed and very
low torque to run nuts down to seated position prior to tightening on an
application. This mode applies a very small amount of torque just to overcome
the resistance of running nuts down onto bolts for a short duration.
2. TORQUE MODE: Used for to apply high torque to fully tighten bolts with
required loads.
The tool is switched between TORQUE and RUNDOWN by setting the dual speed
switch beneath the barrel of the tool. Switch to TORQUE for torque operations,
and RUNDOWN to run down nuts. Always be sure the switch is fully engaged in
either position, never in the middle.
