When the trigger is pressed, the throttle valve moves
downward to the PULL position, and pressurized air is
directed to the bottom of the air piston, causing it to
move upward (Figure A). The air above the air piston
is exhausted and directed through the center of the
throttle valve and out the bottom of the tool.
As the hydraulic rod moves upward, a column of uid
is forced into head, which moves the pull piston back-
ward. 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,
sends the throttle valve to the up (RETURN) position.
Pressurized air is re-directed to the top of the air piston
(Figure B), causing the air piston and hydraulic rod to
move downward.
The air from below the piston is exhausted through
the bottom of the tool, and springs force the pull pis-
ton to return to its home position. The damper valve
(Figure A) impedes oil ow at pinbreak to prevent “tool
kick.”

Fill and Bleed
This section documents the “bleed-&-fill” procedure. For
component identification, see Figures 1, 2, & 3.
REQUIRED EQUIPMENT
• Automatic Transmission Fluid (ATF) DEXRON III,
or equivalent (Refer to Specifications for more
information.)
• Shop air-line with 90–100 psi (6.2–6.9 bar) max.
• Air regulator
• Fill Bottle Assembly (P/N 120337, supplied with tool)
• Large flat-blade screwdriver
• Stall Nut (P/N 124090
or 125340, optional)
• Nose assembly
• Fasteners (optional)
PREPARATION
• Install air regulator in
the air-line and set the
pressure to 20–40 psi
(1.4–2.8 bar).
• Add an approved hydrau-

the Fill Bottle.
TO BLEED AND FILL THE TOOL:
0. Lay the tool on its side with the fill port facing up, and
remove the bleed plug from the fill port.
0. Connect the tool to shop air-line. If fluid is present,
hold the tool over a suitable container with fill port
facing into container. Cycle the tool several times to
drain old fluid, air, and foam. (Figure 2)
0. Screw the fill bottle into the fill port.
0. Stand the tool upright on a bench. Trigger the tool
slowly (20–30 cycles), and bend the fill bottle at a
right-angle to the tool. (Figure 3) When air bubbles
stop accumulating at top of the bottle, stop cycling
the tool. When the trigger is released, the pull piston
returns to the idle position (full-forward).
0. Disconnect the tool from the air-line.
0. Lay the tool on its side and remove the fill bottle. Top
off the fluid in the fill port, and install and tighten the
bleed plug.
0. Connect the air-line to the tool and measure the
stroke. If the stroke is less than .900 inches, remove
the bleed plug and add fluid. Re-insert the bleed plug
and recheck the stroke.
To measure stroke:
0. Cycle the piston all the way forward and measure
distance between front of cylinder head and front
of hydraulic piston (X).
0. Cycle and hold the trigger until hydraulic piston
is in the back position. Measure distance between
front of cylinder head and front of hydraulic
piston (Y).
Stroke = Y-X
0. Increase the air pressure to specifications. Install
two fasteners to check the function and installation
in a single stroke, or cycle the tool with a stall nut
fully threaded onto the piston to load up the tool.
Measure the stroke again. Remove the plug and
add fluid. Re-insert the plug and cycle and measure
again. Repeat this process until the stroke meets the
minimum requirements.

Troubleshooting
Always check the simplest possible cause (such as a loose or disconnected trigger line) of a malfunction first. Then
proceed logically, eliminating other possible causes until the cause is discovered. Where possible, substitute known
good parts for suspected defective parts. Use this Troubleshooting information to aid in locating and correcting
trouble. NOTE: “Piston drift” is when the air piston is in the down position, but the hydraulic pull piston is not in the
full-forward position. This causes an out-of-sequence condition.
1. Tool fails to operate when trigger is pressed.
a. Air-line not connected.
b. Worn or damaged throttle valve O-rings.
c Broken throttle valve cable.
2. Tool does not complete fastener installation.
a. Air pressure too low.
b. Worn or damaged air piston O-ring.
c. Air in hydraulic system. See the Fill and Bleed
section.
3. Pintail stripped.
a. Check for broken or worn jaws in nose assembly.
See Nose Assembly Data Sheet.
b. Check for loose retaining nut.
