WARNING: Under no circumstances should the maximum working load be
exceeded. Always use a load cell or other calibrated indicating device to monitor
the line pull on the tong to avoid an overload.
Use on couplings
The yoke plates attached to the handle have three holes. One hole is used to fix the belt to the
yoke plates. One hole is marked “PIPE”, when this hole is fixed to the handle, the tong will
latch on the pipe for the appropriate belt. The third hole is marked “COUPLING”, this hole
will allow the tong to be latched onto a coupling with a diameter of one inch over the pipe
diameter.
