2.Positioning the work bed:
2.1 Low bolster(fig2):
A. Put a small amount of tension on the cable by cranking the winch up, taking weight off the
pins. This frees the pins in the end of the bolster next to the winch (or right side of the press).
Pull the loose pins out.
B. Raise the other end of the bolster by pulling slightly on the handle until the other two pins are
free.
C. Crank the winch for either up or down movement of the work bed. Reassemble the pins.
As put down STP-15's low bolster, user hand can't leave the winch handle and user foot can't
stand under the bolster (Fig2-1).
If user hand leave the handle will cause bolster to fall down
sharply.
No matter raising or lowering the bolster, must assemble pin from front to back hole
completely.
When bolster position is ready and support pins are inserted completely then turn a little the
winch handle to
release cable
. That because nervous cable maybe broken or make metal
fatigue as bolster pressured.
To prevent cable breakage, never raise or lower the bolster while it holds a load.
Inspect the entire length of the lifting cables at least every three months. Replace any cable
that appears frayed, worn, or crushed. The cables must run on the pulleys easily, and the
pulleys must be free to turn. Careful cable maintenance will help prevent cable breakage.
Remove banding from the press and shipping pallet, and remove all cartons. Stand the press upright.
Refer to the part list, and follow these instructions during the assembly of hydraulic components and
accessories.
