include perishable
parts and should be kept on hand at all times. Other
components, as experience dictates, should also be kept
for replacements.
Always replace O-Rings and Back-
up Rings when tool is disassembled for any rea-
son.
The efficiency and life of any tool depends upon proper
maintenance and good service practices. Tool should
be serviced by personnel who are thoroughly familiar
with it and how it operates.
A clean, well-lit area should be available for servicing
the tool. Special care must be taken to prevent contam-
ination of pneumatic and hydraulic systems. Proper
hand tools and soft materials to protect tools must be
available. Use only standard hand tools, brass drift and
wood block. Vise with soft jaws should be available.
Unsuitable hand tools will cause installation tool dam-
age. All parts must be handled carefully and examined
for damage and/or wear. Components should be disas-
sembled and assembled in a straight line without bend-
ing, cocking or undue force. Disassembly and assem-
bly procedures outlined in this manual should be fol-
lowed. If Huck recommended procedures are not fol-
lowed, the tool may be damaged.

TOOL MAINTENANCE
The 2012 series require a minimum amount of mainte-
nance. Regular inspection and correction of minor prob-
lems will keep the tool operating efficiently and prevent
downtime.
Using filter-regulator-lubricator unit is highly recom-
mended for safe and reliable tool operation. If a filter-reg-
ulator-lubricator unit is not being used in the air supply:
(1) Remove hose fitting from air inlet connector and drop
in a few drops of automatic transmission fluid or light oil.
(2) Blow out air line to remove dirt and water before con-
necting air hose to tool. At regular intervals, depending
upon use, replace all seals in tool. Service Kits should be
kept on hand. Inspect both hydraulic pistons, and their
piston rods for scored surfaces, excessive wear or dam-
age, and replace as necessary.
Always replace seals and back-up rings when tool is
disassembled for any reason to assure proper sealing
and tool function.
NOSE ASSEMBLY MAINTENANCE
Frequently cleaning the nose assembly is recomended.
Remove nose assembly from tool and disassemble.

section. Check components for any
signs of damage, e.g. cracks, scores and spring dam-
age. Check gripper teeth for damage. Remove any
debris packed between teeth with a sharp pointed
‘pick’. Periodically dip nose, while cycling tool, in miner-
al spirits, isopropyl alcohol or other suitable solvent, to
clean jaws and wash away metal chips and dirt.
