WARNING:
Maintenance personnel
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 GB784TK is recommended.
CLEANING AND LUBRICATING PROCEDURE

reduce downtime and increase life of components. Using sewing
machine oil, or an equivalent cleaner/lubricant, follow
instructions below.
1. Disconnect tool vacuum line (if equipped).
2. Point nose assembly into oil as shown (Fig. A).
3. Cycle tool 8-10 times and wipe dry.
