DAILY MAINTENANCE
Note:
•
Dispose of hydraulic oil in accordance with manufacture safety datasheet.
•
All tool materials are recyclable except rubber o
’
rings, seals and wipers.
The performance of any tool depends upon good maintenance practices. Following these minimal requirements daily will extend the
life of your tool.
* Only use a clean dry air supply set at 90
-
100 p.s.i. (6.2
-
6.9 bar) Max. equipped with a filter
-
regulator to prevent wear.
* Check tool and nose assembly for damage. (Replace/Repair if necessary). See overhaul (pgs.14
-
16) for tool repair.
* Inspect hoses and couplings for wear, damage and leaks. (Replace/Repair if necessary). (See hydraulic thread preparation below).
* Verify that hydraulic hose fittings and couplings, air and electrical connections are secure. Tighten, Replace or Repair if necessary.
* Cycle the tool several times to assure there are no leaks during use. (See hydraulic thread preparation below).
* Keep hydraulic system free of dirt.
* Proper care by operators is necessary in maintaining full productivity and reducing downtime.
* 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 on a daily basis.
* All Screwed End Caps, Base Covers, Air Fittings, Air Actuators, Screws and Nose Assemblies are to be examined at the end of each
working shift to check that they are secure.
* For a complete overhaul, service tool kit (GB740SHTK) is recommended (see overhaul pgs. 14
-
16).
WEEKLY MAINTENANCE
•
Keep the hydraulic system full (only use Dexron® III or equivalent) and free of air by using the air bleeder assembly (704153) on a weekly
basis or as needed. (See Filling and Bleeding procedure pgs. 11
-
12).
SEE TROUBLESHOOTING (PG. 13) AND OVERHAUL (PGS. 14
-
16) FOR FURTHER GUIDANCE.
WARNING
:
Tool must be maintained in a safe working condition at all times and examined on a daily basis for damage or
wear. Any repair must be done by qualified personnel trained on Gage Bilt procedures.
WARNING
:
Excessive contact with hydraulic oil and lubricants must be avoided.
WARNING:
Maintenance personnel
MUST
read and understand all warnings and cautions.
WARNING
:
Disconnect tool from its power source before performing maintenance, cleaning or when replacing worn or
damaged components. Severe personal injury may occur if power source is not disconnected.
WARNING:
Read safety datasheet documents for all applicable materials.
CLEANING AND LUBRICATING PROCEDURE
LUBRICATING
Lubricate nose assembly after each cleaning
and as often as needed.
1.
Disconnect tool vacuum line (if equipped).
2. Point nose assembly into oil as shown.
3. Cycle tool 8
-
10 times and wipe dry.

actual tool
Daily cleaning and lubrication of nose assembly will greatly reduce downtime and increase life of components. Using sewing machine
oil, or an equivalent cleaner/lubricant, follow instructions below.
HYDRAULIC THREAD PREPARATION
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 545 or equivalent or a non
-
hardening Teflon®
thread compound such as Slic
-
tite®. Tighten until fitting feels snug and then continue to tighten 1/2 to 1 full turn.
CAUTION:
Over
tightening can easily distort the threads. DO NOT USE TEFLON® TAPE.
CAUTION:
Teflon® tape is an excellent thread sealer, however,
if it is not properly applied, pieces of Teflon® may enter the hydraulic system and cause malfunction or damage.
CLEANING
Clean nose assembly daily or as often as needed.
1.
Dip into mineral spirits or similar solvent to clean jaws
and wash away metal chips and debris. DO NOT allow
jaws to come in contact with other solvents. DO NOT let
jaws soak. Dry jaws immediately.
2.
Disassemble nose assembly and use a sharp
“
pick
”
to remove embedded particles from grooves of jaws.
