Poweramp POWERHOLD SC 4.2003 - Manual (Page 14)

MECHANICAL RELEASE
SIGNAL LIGHTS CHECK
To assure dock attendant safety, check to make sure that the inside and outside
signal lights function correctly. This check should be performed on a weekly basis.
The correct sequence of light operation can be found in the general information
section of this manual.
The POWERHOLD restraint is equipped with a mechanical release that can be
utilized in the event of an electric and/or hydraulic failure which prevents the unit from
releasing the truck ICC bar via normal operating methods.
MATERIAL REQUIRED
1-1/8" Wrench
Phillips head screwdriver
2-1/2' or longer, 3/4" rod
Hammer
Oil (WD-40 or equivalent)
WARNING - POSSIBILITY OF SERIOUS INJURY
Keep all body parts out of the working zone of the restraint weldment (P/N
9414-0014) at all times when performing a mechanical release.
PROCEDURE
1. Make sure outside signal lights are red.
2. Chock truck wheels.
3. Apply a liberal amount of oil to the top of the slide block (P/N 9413-0022).
4. Use the screwdriver to remove the front cover plate (P/N 9411-0012) from the front
of the housing weldment (P/N 9414-0029). This requires the removal of four
screws.
5. Use the wrench to remove the capscrew (P/N 2101-0118) from the front of the
housing weldment.
6. Insert the 3/4" rod through the front of the housing weldment (i.e., through the
area of the weldment opened by the removal of the front cover plate). Set one end
of the rod into the hole located in the front of the slide block.
7. Hammer on the exposed end of the 3/4" rod to force the slide block towards the
face of the dock. The restraint weldment (P/N 9414-0014) should lower when the
slide block is repositioned.
8. After truck is released and away from the restraint, reassemble the unit.
9. Determine cause of electric and/or hydraulic failure.
