Regulating the cutter
Pressure regulation
BC18 - check that the pressure from the load valve does not exceed 190 bar.
BC25 - check that the pressure from the load valve does not exceed 250 bar.
If you use the device over the allowable pressure, it reduces the lifetime of the device.
Cutting blade
The blade is mounted on the BC18 cutter's frame with the aid of six M16x50 (8.8) bolts,
DIN 7991.
The blade is mounted on the BC25 cutter's frame with the aid of six M16x40 (10.9) bolts,
DIN 961.
The cutting blade must be kept sharp for optimum results from the cutter. It is extremely
important for sharpening to be performed correctly. We recommend the use of a file when
sharpening. If there is a considerable amount to be sharpened, you should first use a grinding
machine. We do not recommend sharpening with a corner grinder, although if this does take
place, take care to ensure that the material does not become too hot. This can affect the use of
the product.
Regulating the tilting speed
The BC18 energy cutter is supplied with a relief valve intended for the tilt function. The tilt
function has a default working pressure of 175 bar.
If the machine/system in which the BC18 is installed has a working pressure that is higher or
lower than 175 bar, you may need to adjust the adjustment screw in or out. As a result of this,
the tilt will commence later or early, depending on your choice. In this way, the tilt can be
adapted to the wishes of the user.
If you want to use BC18 as a grapple, the tilt has to be locked. This is done in the tilted down
position. Begin by closing the grapple so that it tilts down, undo the locking nut (1) and then
screw in the adjustment screw (2) 3
–
4 turns. Finish by tightening the locking nut (1). The tilt
cylinder is then locked in the tilted down position.
When the tilt function is to be used again, adjust the adjustment screw so that the cutter tilts at
the desired pressure.
