JIMMY SERIES HYDRAULIC REBAR BENDERS — OPERATION

OPERATION

Control Valve Lever

1.This hydraulic pump has a 3-way, 3-position valve that is activated by a control valve lever (Figure 8). In the neutral position, “PORT A” is CLOSED, meaning there is no flow of pressurized fluid.

Figure 8. Control Valve Lever (Neutral Position)

2.In the forward (extend) position, “PORT A” is OPEN, meaning the flow of pressurized fluid is allowed (Figure 9) and the hydraulic cylinder will extend once the remote control toggle switch is pressed.

Figure 9. Control Valve Lever (Forward Position)

3.In the reverse (retract) position, “PORT A” returns hydraulic fluid back into tank (Figure 10) and the hydrau- lic cylinder retracts.

Figure 10. Control Valve Lever (Reverse Position)

The cylinder on the JB5135 and JB7135 models retract when the

NOTE control valve lever is in the forward position and extend when the lever is in the reverse position. See Figure 15.

Remote Control Unit

1.On the remote control unit there is a toggle switch. When pressed, this toggle switch (Figure 11) will activate (extend) the hydraulic cylinder. Releasing the toggle switch will hold the cylinder in place.

The Remote Control Unit does not

NOTE retract the hydraulic cylinder. The retraction of the cylinder must be done manually (Power Unit).

Positioning the Rebar Bender (Method 1)

For Models JB5090, JB7090, JB8090, JB9180, JB11090

1.Place the pump control valve lever (Figure 8) in the neutral position.

2.Place the rebar bender over the rebar between the main roller and upper roller arm at the desired elevation of the bend as shown in Figure 12. Use vise-grips to hold the rebar bender base in place.

3.Rotate the rebar bender until the hydraulic cylinder is in the opposite direction of the desired bend.

CAUTION

Make certain the area is clear of bystanders before starting the bending process.
