SAFETY CONSIDERATIONS

PRECAUTIONS WHEN USING 8991

Threading

  WARNING

15.Operate the unit with great care.

- Always work with great attention to how you handle and operate the machine and the surrounding conditions.

Carelessness may result in accident or injury.

- Do not operate the machine when concentration is lowered such as when tired, after drinking alcohol, when sick or

affected by medicine, etc.

16.Do not handle the power cord carelessly.

- Do not carry the machine by the cord, or pull the plug out of the socket with the cord.

- Do not place the cord near heated objects, fats and oils, cutters or objects with sharp edges.

- Take care not to tread on the cord, pull it or apply unnecessary force resulting in damage to the cord. Doing so may

result in electric shock, or a short-circuit may occur and cause a fire.

17.Perform careful maintenance daily.

- When changing accessories and parts, follow the operation manual.

- Periodically inspect the power supply cord and plug. If damaged, ask your distributor or WHEELER-REX for

repairs. If you don’t do so, there is a risk of electric shock or short-circuiting and fire.

- If an extension cord is used, inspect the cord periodically and, if damaged, replace it. If extension cords are used

outdoors, use extension cords designed for outdoor use to prevent electric shock, short-circuit or fire.

- Keep parts used for gripping the unit with your hands dry and clean, and free of oil and grease. If your hands slip,

you may be injured.

18.Check for damaged parts.

- Before using the machine, carefully check for any damage to the protective cover and other parts, and check both

normal operation and specified functions.

- Check for any abnormalities such as adjustment of movable parts, tightening, damage to and installation of parts and

all parts affecting operation.

- Do not use the machine if it has a damaged power cord or plug. Doing so may cause electric shock or a short circuit

leading to fire.

- Do not use the machine if the Stop and Start switches do not work properly.

- When replacing or repairing a broken protective cover and other parts, follow the operation manual. If no instructions

are specified in the operation manual, ask your distributor or WHEELER-REX for repairs.

19.Store carefully when the machine is not in use.

- Store in a dry place away from children and locked with a key.

20.For overhaul and repair of the machine, ask an appointed REX agent.

- Our products comply with corresponding safety standards. Do not remodel.

- Be sure to ask your distributor or WHEELER-REX for any repairs. If repairs are carried out by unskilled or

unqualified personnel, the performance of the unit will be adversely affected and may result in accident or injury.

  WARNING

1.Take care when handling the blades.

- To prevent accidents and injuries, take special care when handling blades such as dies, reamers, pipe cutters etc.

2 .Do not put your hands or face near rotating parts when the machine is in use.

- You could get caught in rotating parts or hit by scrap, resulting in accident or injury.

3.Do not start on the next job while the machine is still rotating.

- When you turn the switch off, the machine will not stop rotating immediately. Perform the next job only after

checking that the machine has come to a complete stop. Failure to do so may result in accident or injury.

4 .Do not wear gloves when operating the machine.

- Gloves may get caught in rotating parts or blades, resulting in accident or injury.

5.Do not leave the machine while it is still rotating.

- Others may be injured.
