Leq reflects the
equivalent noise
level result of
installing 1,500
typical Huck
fasteners for an
eight hour work
day.
To calculate equivalent noise level for other quantities of
fasteners in an eight hour period, use the formula:
Leq = SEL + 10 log (n/28,800)
where n = number of fasteners in eight hours.
For an eight hour work day, installing 1,500 typical Huck
fasteners will result in an equivalent weighted RMS
vibration level A(8) of:
2.5 m/s2
To calculate equivalent vibration level for other quantities of
fasteners in an eight hour period, use the formula:
Equivalent Vibration Level, A8 (m/s2) = (n/480) x 0.8
where n = number of fasteners in eight hours,
and
0.8(m/s2) = Aeq for 60 seconds.
Test data to support the above information is on file at Alcoa Fastening Systems, Commercial Products Division, Kingston
Operations, Kingston, NY, USA. Vibration measurements are frequency weighted in accordance with ISO 8041 (1990).

AIR PISTON
PULL
RETURN
When the trigger is depressed the throttle valve
moves to down position, 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
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 9
Turn tool so front of head faces you and remove the relief
valve plug (83). Prior to removing Plug (83), it is
advisable to back out setscrew inside of plug by
approximately 1/2 turn counterclockwise. (See Figure
7a). This ensures that the Piston will remain in fullforward position. and install relief valve ball (87), guide
(86), sleeve (85) and spring (84). Replace the plug (83)
and re-tighten setscrew.
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.

approx. 1/2 turn.
SECTION A-A
from figure 9
Step 10
Unlock Fill Tool and check Reservoir red line. At this
point cycle tool with Stall Nut (Optional see note:)
attached 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 13
Remove fill tool and stall nut (if used). Install a nose
assembly and pull several fasteners to test function.
Step 11
Re-lock the fill tool in out position. Lay tool on its left side
and remove plug (64). Top off reservoir - - place 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).
!
WARNING - Failure to re-lock the fill tool will
result in oil being ejected from the head under
pressure during the topping off of the
reservoir. Severe personal injury may result.
