Note: After the machine has extended the Right/Left Full Band cylinders, the Right Band Out reed switch should be lined up with the Right Band magnet, which turns the switch on. This is what the machine is waiting for.

If the Right Band Full cylinder is fully extended,

– Check the air gap distance between the Right Band Out reed switch and the magnet. The distance should be a maximum of 1/8 inch (3 mm). If it is within the suggested range then the reed switch needs to be replaced.

If the Right Band Full cylinder is partially extended,

– Check that a foreign object is not preventing the Right Band Full cylinder from extending.

– Electric power or hydraulic power or hydraulic return has been disconnected or shut off from machine.

– Remove and observe all 4 Band Position check valves. If the snap ring in the bottom of the check valve is missing then the check valve needs to be replaced. If you are unable to push the plunger from the end of the check valve in and it spring back, then the check valve needs to be replaced.

If the Right Band Full cylinder is still retracted,

– Check that hydraulic power is still on to the machine and that return line is still connected.

– Check that a foreign object is not preventing the Right Band Full cylinder from extending.

– Remove and observe all 4 Band Position check valves. If the snap ring in the bottom of the check valve is missing then the check valve needs to be replaced. If you are unable to push the plunger from the end of the check valve in and it spring back, then the check valve needs to be replaced.

– Check that the directional valve is not stuck.
