Operation
Controls
The operating controls are shown on Figures 1 and 2 on page 16.
The engine on-off switch is used to allow starting of the engine and to turn off the engine.
The engine start switch (located under the gasoling tank) is used to start the engine. The
engine is started by a 12 volt battery located under the main portion of the console.
The throttle control lever is used to adjust the engine speed. It is recommended that the
engine operate at full speed during operation. The engine is adjusted to a full speed of 2800-
3000 RPM. A slower speed will not allow the unit to operate at full potential and a higher
speed may cavitate the pump causing damage to the pump.
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 beside the engine, is dirty and must
be replaced. Use Hycon MFE80/125/2 element or equal.
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 pressure control knob is used to adjust the overall system pressure. Turn the knob
clockwise to increase pressure or counter-clockwise to decrease system pressure.
WARNING: Never operate the tong with a pressure higher than required to
perform the make up or break out operation. Operation at excessive pressure
may damage the downhole tool and/or injure personnel.
The hydraulic pressure gauge is used to indicate the current system pressure in psi. A
conversion chart for equating the hydraulic pressure in psi to the torque output in ft-lbs is
located on page 15.
Loading
To load the downhole tool in the unit, slide the vise left or right as needed. Adjust the vee-
saddle to support the tool when set into the vise. Set the tool into the vise. Position the tong
for make up or break out as needed and set the tong onto the tool. Adjust the vise and tong
as described and latch the vise chain and tong chain.
CAUTION: The vee-saddles must be used to support the tool while torquing.
