Describes something you must not do.
Describes something you must do.
In low temperature environments, check that the sheave is not
frozen before working.
Failure to do so may damage the rope from rotation failure of the
sheave due to freezing.
In high temperature environments, lubricate periodically.
In high temperature environments, depletion of lubricant is severe and
if the lubricant dries up, it will cause damage to the sheave and shaft
and rotation failure for the sheave.
Do not use or store in the following environments.
・
Places with extreme temperature changes
・
Places with corrosive or acidic gas
Doing so will cause rotation failure or strength deterioration.
Do not use while submerged such as in the sea or water.
Doing so will lead severe rotation failure or strength deterioration due
to adhesion of foreign matter or corrosion.
Do not let the pulley touch sharp objects or abrasive surfaces.
Doing so will cause the pulley to weaken due to damage or abrasion.
Do not let the sheave rotate continuously at high speeds for long
periods of time.
Doing so will cause the lubricant to dry up and wear out the sheave
and shaft due to frictional heat.
Use within the temperature range between -18℃ and 66℃.
Using outside of this temperature range will cause rotation failure or
strength deterioration.

Do not use for the purpose of hoisting people or equipment with
people in it.
Doing so may lead to serious injury or a fatal accident.
Do not apply loads that exceed the working load limit.
Doing so may damage the pulley, drop the hoisted load, and lead to
serious injury or a fatal accident.
Do not apply impact loads.
Doing so may lead to serious injury or a fatal accident due to a broken
pulley or other part, or falling hoisted loads.
Do not ride on top of hoisted loads or pulley equipment.
Doing so may lead to serious injury or a fatal accident due to falls or
falling hoisted loads.
Do not use when there are people within the movement range of
the hoisted load or under the pulley.
Doing so may lead to serious injury or a fatal accident.
When hoisting, stay away from the pulley, rope, and around and
under the hoisted load.
Failure to do so may get your hands or body caught or you may get
crushed under the falling hoisted load, lead to serious injury or a fatal
accident.
Do not use the swivel for purposes such as constant rotation.
Doing so may damage the swivel, drop the hoisted load, and lead to
serious injury or a fatal accident.
Do not perform modifications such as welding or cutting.
Doing so may lead to serious injury or a fatal accident due to a
weakened or broken pulley.
Inspect before use and periodically.
Failure to do so will overlook abnormalities or damage to the pulley,
and may lead to serious injury or a fatal accident.
Do not let the rope fixture touch the pulley.
Doing so may damage the pulley and lead to an accident of a falling
hoisted load.
Attach the hoisted load so that the sheave and hoisted load
fixture are in tandem.
If the load is applied to the pulley from the side, it may lead to serious
injury or a fatal accident due to breakage.
After starting to hoist a load, check that the rope is in the groove
of the sheave.
Failure to do so may drop the hoisted load due to rope damage, and
lead to serious injury or a fatal accident.
Do not use during bad weather such as in strong winds.
Doing so may drop the hoisted load and lead to serious injury or a
fatal accident.
When attaching, removing, or transporting a pulley, use
slip-resistant protective gloves and perform work in a stable
place.
Failure to do so may drop the pulley and lead to serious injury or a
fatal accident.
