Poweramp POWERHOLD 4.2003 - Manual (Page 14)

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 (P/N
9413-0022), could result in abnormal operation of the restraint.
LUBRICATION
Inspect the POWERHOLD restraint pivot points for wear or damage during normal dock
leveler maintenance cycles.
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 (P/N 9413-0022) 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 (P/
N 9414-0029).
Lubricate the slide block guide channels and the restraint weldment (P/N 9414-
0014) 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".
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 approved:
Flomite 530 ZF from Poweramp
Part# 8512-0001 for 1 Gallon Container
Part # 8512-0002 for 5 Gallon Container
Aero shell Fluid 4 or Fluid 41#60421 by Shell Oil Co.
Mobile Aero HFA Mil-HS606A or Aero HF by Mobil Oil Co.
Texaco Aircraft Hydraulic Oil 15 or 5606 by Texaco Oil Co.
Exxon "UNIVISJ13" by Exxon Oil Co.
Note:
Use only aircraft hydraulic fluids designed to meet or exceed Military Specification: Mil-L-
5606
Fluid brands can be mixed. Do not mix with fluids other than those listed.
Warranty repairs must use Poweramp and DLM supplied hydraulic fluids to qualify for
fluid cost reimbursement.
Using non-approved fluids may effect equipment operation and will void warranty.
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.
