Poweramp POWERHOLD STD & SC 11.2006 - Manual (Page 13)

MAINTENANCE
CLEANING
The POWERHOLD restraint should be kept free of debris, ice, dirt and sand. Build-ups
of foreign material, especially on the top of the slide block assembly, could result in
abnormal operation of the restraint.
LUBRICATION
Lubrication should be performed on a monthly basis. Use Lubriplate No. 18339 multi-
purpose grease or equivalent.
Remove all of the old grease from the slide block guide channels and from the top of
the slide block before applying the new grease. The slide block guide channels are
located inside the unit, on the sides of the housing weldment.
Use the grease zerks located outside the unit, on the sides of the housing weldment to
lubricate the slide block guide channels and the restraint weldment pivot point. Also,
apply a liberal amount of grease on top of the slide block, especially at the areas of the
slide block on which the restraint weldment "rides".
NOTE: DO NOT GREASE THE TOOTHED PORTION OF THE RATCHET BAR OR
LOCKING MECHANISM.
HYDRAULIC FLUID CHECK
The hydraulic fluid level should be checked every month. Fluid level should be
approximately 1-1/2" from the top of the reservoir when the restraint is in the fully
lowered (stored) position.
To assure normal operation of the restraint the following fluids are recommended:
Flowmite 530 ZF available from Systems, Inc.
Aero shell fluid #4 code or #41 by Shell Oil Co.
Mobile Aero HFA Mil-HS606A or Aero HF by Mobil Oil Co.
Texaco Aircraft Hydraulic Oil 15 or 5606
Exxon UNIVIS J13
NOTE: Use of hydraulic fluids with equivalent specifications to those listed is
acceptable. Use of fluids that do not have equivalent specifications will result
in abnormal operation of the unit.
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.
