LIFT CYLINDER
This is a direct-acting valve. Pushing the valve handle forward will cause the lift cylinder to lift the tong vertically. Pulling the
valve handle in the opposite direction will cause the lift cylinder to lower the tong.

SHIFTING GEARS
The shifting shaft has three "detent" positions identifying the low speed/high torque position, the "neutral" or free-spinning posi-
tion, and the high speed/low torque position. The detent strength may be adjusted by releasing the locknut on the detent tube
and increasing or relaxing pressure on the detent spring. Ensure the locknut is tightened once the desired detent pressure has
been set.
To shift to the high-speed gear, move the shifting handle upward from neutral position. To shift to the low-speed gear, move
the shifting handle down through the neutral detent to its lowest position. Note that the high clutch gear or the low clutch gear
may not be exactly aligned when shifting, so the operator may need to "bump" the motor control handle slightly to turn the main
clutch gear shaft and shifting collar into alignment. This is most effective when applying a small amount of pressure on the gear
shift lever in the direction you want to shift the tong, ensuring the shifting collar will "catch" when the main clutch gear aligns
with either the high or low clutch gear.
