254 and 254OS Pneudraulic Installation Tools (HK1172)

    

GENERAL 

The operating efficiency of a tool is directly related to the 

performance of the entire system. Regular inspection and 

immediate correction of minor problems will keep a tool 

operating efficiently, and prevent downtime. A schedule 

of preventive maintenance of the tool, nose assembly, 

hoses, trigger and control cord, and Powerig® Hydraulic 

Power Source will ensure proper tool operation and 

extend its life. 

NOTE: This Huck tool should be serviced 

only by personnel who are thoroughly familiar with its 

operation.

Service the tool in a clean, well-lighted area. Take special 

care to prevent contamination of pneumatic and hydraulic 

systems.

Keep all necessary hand tools on-hand and available.
Carefully handle all parts. Before reassembly, examine 

them for damage and wear.

Disassemble and assemble tool components in a straight 

line. Do NOT bend, cock, twist, or apply undue force.
Keep Spare Parts Service Kit, 254KIT, available when 

servicing the tool; it includes important perishable parts. 

Other components, as experience dictates, should also be 

available. See Kits & Accessories

DAILY 

If a Filter-Regulator-Lubricator unit is not being used, 

uncouple the air disconnects and add a few drops of 

hydraulic fluid or a light-weight oil to the air inlet of the 

tool. 

NOTE: If the tool is in continuous use, add a few 

drops of oil in every 2–3 hours.

Before connecting an air hose to the tool, clear the air 

lines of dirt and water.

Check all hoses and couplings for damage and air leaks; 

tighten or replace if necessary.

Check the tool and nose assembly for damage and air or 

hydraulic leaks; tighten, repair, or replace if necessary.
Inspect the tool, hoses, and Powerig during operation to 

detect abnormal heating, leaks, or vibration.

Clean nose assemblies 

in mineral spirits to clear jaws and 

rinse metal chips and dirt. For a more thorough cleaning, 

disassemble the nose assembly. Use a pointed “pick” to 

remove embedded particles from the jaws grooves.

Clean

 all parts

 of 

any assembly with Unitized

 Jaws in 

mineral spirits or isopropyl alcohol only; do not let jaws 

come in contact with other solvents. 

Do not let jaws soak; 

dry them 

immediately

 after cleaning. Huck recommends 

drying other parts before re-assembling.

Periodically, check the tool stroke. If the stroke is short, 

add fluid.

WEEKLY 

Disassemble, clean, and re-assemble nose assembly in 

accordance with applicable instructions

.

Check the tool and all connecting parts for damage and 

fluid/air leaks; tighten or replace if necessary

.

Maintenance

CAUTIONS:  

Replace all seals, wipers, and rings when the 

tool is disassembled for any reason, and at 

regular intervals, depending on severity and 

length of use.

Do not use TEFLON

®

 tape on pipe threads. 

Tape can shred and break free into fluid lines, 

resulting in malfunctions.

CAUTION: Damaged jaw teeth, or debris 

packed between teeth, will result in fasteners 

not being installed or being improperly 

installed.
