SHEET SUPPORT SYSTEM
1. Single Stroke: When the foot pedal is activated, the sheet support will drop down
and remain down until the cycle is complete and then return to the up position.
2. Continuous Stroke: When the foot pedal is activated, the sheet support will drop
down and stay down as long as the foot pedal is activated. When the foot pedal is
released the cutter head will return to top of the stroke and the sheet support return to
the up position.
3. Speed of the System: The speed of the sheet support is regulated by the two flow
controls on the sheet support air valve. The pressure to the system is regulated by the
Filter / Regulator unit that the air supply connects to. Generally 80 psi on the
regulator will give consistent operation providing the incoming air supply is 90 psi or
higher (max 150 psi). The incoming air supply should also have a flow rate of at least
5 cfm with a 3 second recovery time.
4. Dump Time: Rear dump sheet support systems generally have this time set to 0
seconds. The sheet support will drop as soon as the cutter head begins its down
stroke.
Front dump sheet support systems have a slight delay (approximately .5 seconds)
before the system drops.
Please consult the factory for adjustments for sheet support system speed.
MAINTENANCE
On a monthly basis, remove the top cover (11) of each side panel and grease the gib
plates (9, 10, 15). This can be best accomplished by jogging the cutter head down to the
extreme down-stroke position, thus exposing a majority of the gib surface.
MAKE
SURE THE POWER TO THE MACHINE HAS BEEN TURN OFF
WHEN APPLING LUBRICATES.
Also each month, apply grease to the zerk
fitting of the support bearings (53) of the drive linkage shaft (55). Otherwise, periodic
lubrication with a good grade of machine oil to the remaining moving parts such as those
associated with the linkage are of the self-lubricating, oil impregnated composition.
Additionally, the manufactures recommended maintenances schedule for the power unit
of the shear is included in this manual as an appendix.
