OPERATION
SELECTION AND INSTALLATION OF ROLLER AND
COLLAR
1. Select the roller and corresponding collar to match the
diameter of the rebar to be bent. See Table 2 for the
different combinations.
2. Apply multi-purpose grease to the roller.
3. Install the collar and the roller as shown in Figure 2.
4. When using a roller with a bearing, bearing must face
downward.
5. When using a collar with a bearing, bearing must face
downward.
6. To prevent the roller and the collar from coming off,
attach the washer securely with the bolt.
7. Position the stopper so that rebar to be bent is parallel
to the front of the stopper and tighten the rebar securely
in place. If the rebar is not parallel to the front, the
bending angle will be incorrect. See Figure 3.
8. Rotate the Angle Select Dial to the desired angle that
the rebar is to be bent (Figure 4). If the selected angle
cannot be obtained by the Angle Select Dial, "fine tune"
the angle by using the Angle Adjusting Knob (Figure 5).
9. Plug the power cord into a proper single-phase power
source. Make sure that the rebar bender is properly
grounded.
10. Turn the power switch on.
11. Hold the rebar firmly and press the Start Switch. This
will engage the clutch and the roller to bend the rebar.
12. After the rebar is bent to the desired angle, the roller
will automatically spring back to the starting position.
