Excessive contact with hydraulic fluid and lubricants should be avoided.
WARNING:
Maintenance personnel
MUST
read and understand all warnings and cautions.
The performance of any tool depends upon good maintenance practices. Following these minimal
requirements for service and care will extend the life of your tool.
*Only use an air supply set at 90-100 psi. equipped with a filter-regulator to prevent wear.
*The tool will eventually lose some hydraulic oil. Keep the hydraulic system full
(only use Dexron III, or
equivalent)
and free of air by using the air bleeders (704153) on a regular basis.
*Proper care by operator is necessary in maintaining full productivity and reducing downtime. Read all
applicable tool manuals and nose assembly data sheets prior to operating tools.
*Keep nose assemblies, especially jaws, clean and free of chips and debris.
Lube jaws and collet surfaces
that jaws ride on with light machine oil.
*All Screwed End Caps, Base Covers, Air Fittings, Triggers, Screws and Nose Assemblies are to be examined at
the end of each working shift to check that they are secure.
*Check daily all Hoses, Couplings, and Tools for damage or air/hydraulic leaks. Tighten or replace (if necessary).
*For a complete overhaul, tool kit GB740TK is recommended.
