switch is on, the motor may be started.
The POWER ON switch will start the hydraulic pump motor. It contains an indicator light
to show that the motor is on. The POWER OFF switch is used to stop the motor.
The FILTER indicator light is used to monitor the hydraulic filter. If this light is on while a
cylinder is traveling the hydraulic filter element, located in the lower portion of the console,
is dirty and must be replaced. Use Hycon 0085-MA-010-P element or equal.

fully retracted. Failure to do so could damage the lift cylinder, tong, or
downhole tool.

cylinder.
The TONG RATCHET and TONG ENGAGE buttons are used to control operation of the
main cylinder. Press the TONG ENGAGE button to apply torque. Press the TONG
RATCHET button to ratchet the tong back to the pull down position.
The HAND-AUTO selector switch changes the mode of the console from manual to
