Operation
Once the pipe wrench is securely placed on the work piece,
assume a proper operating position. Do not overreach. Keep
proper footing and balance at all times. Do not hang on the
pipe wrench. A proper operating position enables better
control of the tool in unexpected situations. When working
at height (on ladders, scaffolding, etc.) use appropriate work
methods and equipment to ensure stability and safety.
When working on horizontal pipe such as in a pipe vise at
waist height, it is often most effective to use your body weight
to tighten and loosen fittings (Figure 7). Do not lift your feet off
the ground. Keep your feet firmly on the ground to maintain
control of the wrench.
Pulling a wrench typically allows better control in unexpected
circumstances than pushing the wrench.
Only apply force in the direction of rotation. Excessive side
loading of the wrench can cause the wrench to slip or be
damaged.

Do not hang wrench on pipe – always keep a hand on the
wrench. Uncontrolled tools can fall and cause injury. Fittings
can come loose, wrenches can slip – be prepared.
If greater torque is required, do not use handle extensions or
other mechanical, hydraulic or powered devices with the pipe
wrench. Use a larger wrench or a compound leverage wrench.
Other methods may be needed to break connections loose,
such as heat or hammering on the joint (do not hit the wrench).
In some cases, it may be possible to disassemble the system
at the next connection and break the connection loose in a
vise or at a bench.
