PULL:
When the trigger is depressed (1),
the throttle valve moves to down position
(2), and pressurized air is directed to the
bottom of the air piston, causing the
piston to move upward (3). The air above
the piston is exhausted and directed
through the center of the throttle valve
and out the bottom of the tool (4). As the
air piston moves upward, the attached
rod and hydraulic piston and are forced
up (5), and a column of pressurized fluid
is forced into the head, which moves
the hydraulic pull piston back (6). The
attached nose assembly moves with the
hydraulic pull piston to begin fastener
installation.
RETURN:
When fastener installation is
completed, the trigger is released (7). Air
pressure, with the assistance of a spring
(8), causes the throttle valve to return
to its up position (9). Pressurized air is
redirected to the top of the air piston,
causing it to move downward (10). The
air from below the piston is exhausted
through bottom of tool (11). As the rod
and air piston move downward, hydraulic
pressure is reversed and the hydraulic
pull piston is returned forward (12). The
return pressure relief valve protects the
tool against pressure spikes. The reservoir
replenishes the hydraulic system as
needed.
Principle of Operation
1. Remove plastic shipping plug from air
hose and put in a few drops of Automatic
Transmission Fluid, DEXRON III, or equivalent.
2. Screw quick disconnect fitting into Air Inlet
Connector.
3. Set air pressure on regulator to 10 psi above
the attached regulator set point.
4. Attach air hose to air power source.
5. Cycle tool a few times by depressing and
releasing trigger.
6. Disconnect air hose from tool.
7. Remove Retaining Nut and Stop.
8. Select proper Nose Assembly for fastener to
be installed.
9. Attach Nose Assembly.
10. Connect air hose to tool and install fastener(s)
in test plate of proper thickness with proper
size holes. Inspect fastener(s).
NOTE:
Air quick disconnect fittings and air hoses
are not available from Huck International,
Inc.
WARNINGS:
Read full manual before using tool.
Inspect tool for damage or wear before each use. Do not
operate if damaged or worn, as severe personal injury
may occur.
A half-hour training session with qualified personnel is
recommended before using Huck equipment.
When operating Huck installation equipment, always
wear approved eye protection.
Be sure there is adequate clearance for the operator’s
hands before proceeding.
This tool is shipped with an attached regulator and a 1/4” inside diameter air hose (Huck p/n 115436), with a plastic plug
in the air inlet connector. An air supply capable of 6.3 CFM at a pressure greater than 10 psi greater than the installed
regulator set point (Figure 16) must be available. Air supply should be equipped with a filter-regulator-lubricator unit.
Preparation for Use
CAUTIONS:
Do not let disconnected hoses and couplers contact a
dirty floor. Keep harmful material out of hydraulic fluid.
Dirt in hydraulic fluid causes valve failure In Tool and In
Powerig Hydraulic Unit.
Do not use TEFLON
®
tape on pipe threads. Pipe threads
may cause tape to shred resulting in tool malfunction.
(Threadmate™ is available from Huck in a 4oz. tube as
part number 508517.)
