Poweramp POWERHOLD SC 4.2003 - 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 (P/N 9413-0022),
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 (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.

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.
