OPERATING INSTRUCTIONS
Tongs are assembled with parts carefully machined from selected materials. Each tong is thoroughly
tested and inspected and is shipped from the factory with confidence that it will efficiently perform
any job for which it is rated. The ensuing pages have been prepared for your guidance. These
procedures are necessary and should be followed for proper operation and maximum life of your
tong.
FLUID REQUIREMENTS:
To obtain the proper torque in making up and breaking out, the Tubing Tong requires a fluid volume
of approximately 35 to 40 gallons per minute (132.5 LPM to 151.4 LPM) at 2000 PSI (70.3 Kg/sq
cm) and a minimum of 10 GPM (37.8 LPM) at 1000 to 2000 PSI (70.3 to 140.6 Kg/sq cm). Every
effort should be made to keep the hydraulic system clean. The coupling on the tong is self-sealing
and should be used whenever the hoses are disconnected. Use of this type of coupling insures the
pressure and return hoses, four-way valve, and hydraulic motor being full of oil, minimizing spillage.
HOSE CONNECTIONS:
When connecting the hoses, ensure there is no pressure in the system. Detach the fluid pump from
the engine or shut the whole system down. ALWAYS CONNECT THE 1” (2.54 cm) FLUID
RETURN HOSE TO THE TONG FIRST, and then connect the fluid supply hose. ALWAYS
DISCONNECT THE FLUID SUPPLY HOSE FIRST. This prevents any pressure from building up
in the hydraulic motor and seal. When attaching the hoses to the tong, DUST CAPS SHOULD
ALWAYS BE USED WHENEVER HOSES ARE DISCONNECTED. Should the open end of the
coupling be allowed to come in contact with any dirt, it should be very carefully cleaned before re-
connecting and installing dust caps. A very small amount of dirt, sand, or foreign material can cause
serious damage to the pump, hydraulic motor and valves.
