Work Preparation
-
Turn on the power switch. Set the Angle adjustment at about 135, and let the machine run idly for about 3 minutes.

Periodic Check and Maintenance
Precautions
- Do not exceed the machine’s capacity for simultaneous bending. If exceeded, machine failure may result.
- When bending rebars while holding them, watch out for your fingers and prevent accidents.
- Depending on the rebar material, it may fracture during bending, resulting in an accident. Therefore, keep your attention fully focused on the bending work.
- Ensure that no persons or objects are within the radius of the bending rebar.
- Since this machine uses electric power, rain or water may cause an electricity leak. Keep in a dry place or cover with a waterproof film.
- When moving the machine, check that the transportation handle is firmly fixed.
Repairs and Security
- Replacing the carbon brush – Be sure to isolate the power plug from the power source. Check the carbon brush for wear when the machine is not in operation. If the carbon brush in the motor, which is subject to wear and tear, is worn, the motor will lose power or even stop until the power is next turned on. In such cases, the carbon brush(es) must be replaced.
- On the motor inside the machine, unscrew the brush cap with a straight tip screwdriver, and remove the brush together with the spring (replace both of the brushes.)
- When replacing the rotating roller or fixed roller, clean up with a brush.
- Inspection and Security. Check that bolts and nuts are fully tightened from time to time.
- Dry the machine sufficiently after the rainy season or rainfall before operation
- If the rotating roller jolts when returning to its original position, adjust it by unscrewing the spring tension adjustment bolt. If it returns too slowly, tighten the adjustment bolt.
- The machine is ready for operation when the power indicator lamp lights up after power input and power switch. If the lamp is not lit, check the power cable connection.
- If the machine does not start up when the power lamp is lit, check the fuse or check the carbon brush in the motor for wear.
