Huck Model 255 Sound Level
The sound level of the 255 tool cycling without fastener is
Sound Exposure Level (SEL) =84.4 dB (A)
Peak Value = 91.1 dB (C)
The noise of the fastener being installed in structure is
considered process noise, not tool noise. Sound
measurements of simulated process noise are available
upon written request from Huck International in Kingston,
NY, USA.
Huck Model 255 Vibration Level
For an eight hour work day, installing 3000 typical
Huck fasteners will result in an equivalent weighted
RMS vibration level (Aeq) of 8.1m/s2.
To calculate the equivalent vibration level for other
quantities of fasteners in an eight hour period, use the
formula:
Equivalent Vibration Level, Aeq (m/s2) = (n/480) x 1.3
where n = number of fasteners in eight hours, and
1.3(m/s2) = Aeq for 60 seconds.
Test data to support the above information is on file at
Huck International, Inc., Kingston, NY, USA. Vibration
measurements are frequency weighted in accordance with
ISO 8041 (1990).

inspected on a regular basis for damage
or wear. Any repair should be done by a
qualified repairman trained on Huck
procedures.
3Repairman and Operator must read and
understand any Warning and Caution
stickers/labels supplied with equipment
before connecting equipment to any
primary power supply. As applicable,
each of the sections in this manual have
specific safety and other information.
4When repairing or operating Huck

PISTON
AIR PISTON
RELIE
VALVE CHECK
VALVE
PULL PISTON
THROTTLE
VALVE
RESERVOIR
When the trigger is depressed, the throttle valve
moves to down position, and pressurized air is
directed to the bottom of the air piston, causing the
piston to move upward. The air above the piston
is exhausted and directed through the center of the
throttle valve and out the bottom of the tool. The
air piston has a rod and a hydraulic piston
attached. When the air piston rod moves upward,
a column of pressurized fluid is forced into head,
which moves the pull piston back. The attached
nose assembly moves with the pull piston to start
fastener installation.
When fastener installation is completed, the trigger
is released. Air pressure, with the assistance of a
spring, causes the throttle valve to return to its up
position. Pressurized air is re-directed to the top of
the air piston, causing the piston to move
downward. The air from below the piston is
exhausted through bottom of tool. The rod and
hydraulic piston move downward, hydraulic
pressure is reversed and the pull piston is returned
forward. Return pressure relief valve protects tool
against pressure spikes. The reservoir replenishes
hydraulic system as needed.

Step 6
Connect tool to shop air regulated to 20 to 40 psi. Cycle
tool 20 - 30 times. Watch for air bubbles escaping from
the tool into bottle. (You may rock the tool to free trapped
air in the tool.) Do not allow the air to re-enter the tool.
Step 7
When air bubbles no longer appear in bottle, remove fill
bottle while tool is lying on its side.
Step 8
Install the check valve Ball (77), Guide (76) and Spring
(75). Replace the Plug (71). (Fig. 7)
Note: When cycling tool, always hold bottle up as shown
in Figure 8 to prevent drawing in air from empty part of
bottle.
Step 9
Turn tool so front of head faces you and remove the relief
valve Plug (83) and install relief valve Ball (87), Guide
(86), Sleeve (85) and Spring (84). Replace the Plug (83).
Step 10
Unlock Fill Tool and check Reservoir red line. At this
point cycle tool with Stall Nut attached (Optional. See
note.) and retaining nut locked in the full forward position
(“Dead Stall”). Reservoir should not drop below the red
line on the reservoir housing.
NOTE: Dead Stalling is not necessary if Optional Stall nut
was not used; just cycle tool.
Step 11
Re-lock the fill tool in out position.Lay tool on its left side
and remove Bleed Plug (64). Top off reservoir by placing
a few drops of oil in hole and wait for air bubbles to
escape. Push a pin or a scribe into hole to check for
trapped air bubbles. Replace plug. (Fig. 7)
Step 12
Unlock the fill tool and cycle tool as in step 10. Reservoir
may drop slightly. If so, repeat step 11 until when you
touch the fill tool handle it has no pressure against it and
it drops out of the lock position, and the plunger does not
drop when tool is cycled. NOTE: This usually requires 3
to 4 times topping off.
