GENERAL
■ Operators should receive training from qualied
personnel.
■ Do not bend tool to free if stuck.
■ Tool should only be used to install fasteners.
■ NEVER use as a jack/spreader or hammer.
TO INSTALL A BobTail®FASTENER:
1. Check work and remove excessive gap. (Gap is
the space between sheets. Gap is excessive if not
enough pintail sticks through the collar for the nose
assembly puller to grab onto).
2. Put BobTail pin in hole.
3. Slide BobTail collar over pin. (The anged end of the
collar must be towards the pieces being fastened.)
4. Push nose assembly onto the pin until the nose
assembly puller stops against the pin. Tool and nose
assembly must be held at right angles (90 degrees)
to the work.
5. Depress tool trigger to start installation cycle.
6. When forward motion of nose assembly anvil stops,
release trigger. Tool will go into its return stroke and
push off the installed fastener.
7. The tool and nose assembly are ready for the
next installation cycle.
operatIng InstruCtIons
For safe operation. Please read completely
CAUTION: Remove excess gap from between
the sheets. This permits enough pintail
to emerge from collar for ALL puller teeth
to engage with pintail. If ALL teeth do not
engage properly, jaws will be damaged.

Where a special tool is required, the descripon and
part number are given.
• While clamping tool or parts in a vise, and when
parts require force, use suitable so materials to
cushion impact. For example, using a half-inch brass
dri, wood block and vise with so jaws greatly
reduces possibility of damaging tool. Remove
components in a straight line without bending,
cocking or undue force. Reassemble tool with the
same care..
Sealants, Lubricants, Service Kits
•See sPecIFIcatIons for uid type. Dispose of uid in
accordance with local environmental regulations.
Recycle steel, aluminum, and plastic parts in
accordance with local lawful and safe practices.
• Rub pipe plug threads and quick connect ttings
with PTFE thread compound.
• Smear LUBRIPLATE®13OAA*, or equivalent
lubricant, on O-Rings and mating surfaces to aid
assembly and to prevent damage to O-Rings.
(LUBRIPLATE 13O-AA is available in a tube as
Huck P/N 502723.)
•Each Service Kit contains perishable parts for your
specic tool. As foreseeable use may indicate,
keep extra kits (O-rings, Back-up Rings, other
standard items) and tool parts in stock. When stock
is depleted, you can get kit items from any regular
retailer of these items. See kit parts list for: O-ring
size (AS568- number); material; durometer.
PreventIve MaIntenance
System Inspection
Operang eciency of the tool is directly related to
the performance of the complete system, including the
tool with nose assembly, hydraulic hoses, trigger and
control cord, and POWERIG. Therefore, an eecve
prevenve maintenance program includes scheduled
inspecons of the system to detect and correct minor
troubles. At the beginning of each shi/day:
• Inspect tool and nose assembly for external damage.
• Verify that hydraulic hose ttings, couplings, and
electrical connections are secure.
• Inspect hydraulic hoses for damage and deterioration.
Do not use hoses to carry tool. Replace hoses if
damaged.
• Observe tool, hoses, and hydraulic unit during
operation to detect abnormal heating, leaks, or
vibration.
• Max hydraulic uid contamination level: NAS 1638
class 9, or ISO CODE 18/15, or SAE level 6.
Powerig Maintenance
Maintenance instructions and repair procedures are
in the appropriate POWERIG Instruction Manual.
Tool Maintenance
Whenever disassembled and also at regular intervals
(depending on severity and length of use), replace
all seals, wipers, and back-up rings in tool. Service
Kits, hoses, and extra parts should be kept in stock.
Inspect cylinder bore, pistons, and piston rods for
scored surfaces and excessive wear or damage.
Replace as necessary.
Nose Assembly Maintenance
