When kinking, flattening or rippling of larger size conduit is resulting, it’s best to replace the rollers and shafts before replacing the clamping jaw. Usually the rollers have worn out and are just due to be replaced. This will cure about 95% of all these issues. Also, make sure that there is an ample amount of conduit sticking out past the clamping jaw. If the end of the conduit is too close to the clamping jaw, it will start to flatten the conduit as it is bent due to the force being put on the conduit. The bending shoe and conduit may also need to be sprayed with a bit of WD-40. If the conduit is sticking to the bending shoe, it will start to pull and stretch the conduit which can cause deformation in the conduit.
If you are having this problem with PVC-Coated Rigid Conduit, try cleaning the shoe and conduit with rubbing alcohol. This is recommended by one of the leading manufactures in PVC-Coated Conduit.
Bending shoes on the B300 series one-shot and sweep benders can be interchanged from unit to unit provided the bender accommodates that size shoe. There is only one Repair Parts Sheet breakdown for the B300 series. All other required information is located in the catalog.
The B300 series one-shot benders have a bending saddle that adapts to the cylinder shaft via thread. The head of the saddle locks into the bending shoe with the lock pin. A12 saddle is for use with 10 ton cylinders and the A29 saddle is for the 25 ton cylinders. If you need to purchase the cylinder separately as a replacement item, the saddle would have to be ordered also. The saddles are not included when purchasing the replacement cylinders.
A troubleshooting aid exists on the printed circuit board
mounted to the inside of the operating handle. A white L.E.D.
will flash once every two seconds after power up. The L.E.D.
indicates all systems functional. See the Figure below.
Error codes consist of different light patterns.
1. Blink twice, pause, blink twice = the motor is over heated.
2. Blink 3 times, short pause, blink three times, long pause =
limit switch has failed.
3. Blinks 4 times, short pause, blinks four times, long pause =
pendant control malfunction.
In addition the L.E.D. will be steady on if the bend or return
button is being pressed.
When bending PVC-Coated Rigid with the B2000 Cyclone bender you will need to use the EMT side and always use the next size up to bend it. The B2000 can only bend up to 1-1/2″ PVC Coated Rigid. So when trying to bend 1-1/2″ PVC Coated Rigid you’ll want to use the EMT side and the 2″ size in order to bend this conduit. Cleaning the shoe and conduit with rubbing alcohol is also recommended for bending the PVC-Coated Rigid so that it does not attempt to grab the coating material.
Failure to follow these guidelines will cause the conduit to kink and/or flatten. In some instances it will also cause the bending shoe to peal the coating off of the conduit.
If the bender has the 3 button pendant, then the part number is a P05C. If the bender has the older box with a toggle switch and a push button, then a HC12 Handle and Circuit assembly would be needed. The new P05C pendant will not work with an old circuit board.
