- When using a heavy-duty Pipe Wrench, maintain a gap between the back of the hook jaw and the pipe.
- This concentrates the pressure at the jaw teeth only and produces the maximum gripping force and aids ratcheting action.
- If possible, always pull rather than push on the pipe wrench handle and maintain a proper stance with feet firm to hold the balance.
- Inspect Pipe Wrenches periodically for worn or unsafe parts and replace them.

PROPER USE
- When using a heavy-duty Pipe Wrench, maintain a gap between the back of the hook jaw and the pipe.
- This concentrates the pressure at the jaw teeth only and produces the maximum gripping force and aids ratcheting action.
- If possible, always pull rather than push on the pipe wrench handle and maintain a proper stance with feet firm to hold the balance.
- Inspect Pipe Wrenches periodically for worn or unsafe parts and replace them.
ABUSE/MISUSE
- Do not use a Pipe Wrench as a hammer, nor strike a Pipe Wrench with a hammer
- Pipe Wrenches are designed to turn or hold pipe; never use a Pipe Wrench to bend, raise, or left a pipe.
- Never use a pipe extender or leverage
- Do not permit chips to clog flutes as this will prevent the tap from turning.
