Preventive Maintenance Checks and Service
These preventive maintenance recommendations are designed to prevent unexpected
breakdowns and problems through periodic inspection and maintenance. Maintenance
intervals should be based on frequency of usage and operating environment. Frequent
usage, or dirty operating conditions require more frequent servicing. A clean, dry air
supply will help keep the equipment functioning properly. Maintain reports on all
preventative maintenance checks.
Wire Rope and Load Hooks
Wire rope, load hooks and clamps should be inspected on a daily basis. Time intervals
should be based on the frequency of usage and in accordance with standard wire rope
manufacturer's specifications.
Load Positioner Lubrication
Basic Units: There are only three moving parts (ball nut, thrust bearing and piston)
inside the unit that require periodic cleaning and lubrication. Cleaning requires
disassembly of the unit by an authorized service repair center.
• The special lubricants mentioned are recommended for the units and are available
through Ingersoll-Rand.
Lubrication can be accomplished by partial disassembly of the unit while suspended as
follows:
1. On series E and S units, turn pilot regulator screw (counter-clockwise) until wire
rope is slack. On series P units, depress the down lever until wire rope is slack.
2. Remove load from unit.
3. Turn off air supply.
4. Remove wire rope guide, end cap and piston.
5. Using a paint brush (or a similar object) reach through the wire rope window
in the housing and apply lubricant (10886) to ball screw.
• Lubricant (10885) must be used in 227 kg (500 lb.) unit.
6. Using a clean rag, wipe off piston, cylinder bore of housing and ball screw
cap.
7. Apply lubricant (10885) to cylinder bore and outside diameter of ball screw
cap. Reassemble piston, end cap and wire rope guide.
8. Attach control package to end cap. Turn on air.
9. Readjust unit, per Control Operational Adjustments.
Air Supply
Be sure that the air supply is free of rust, dirt, water and oil. Use of a good air filter and in-line regulator
is highly recommended. 6.9 bar (100 psi) is required to operate the unit at its maximum capacity. Lower
pressure reduces unit capacity accordingly. Do not use an air in-line oiler. Oil will damage the unit and
controls.
