Nose Piece Installation:
To change the Nose Piece
1. Remove the NOSE PIECE in the tool by unscrewing
it in a counterclockwise direction.
2. Actuate tool until it is fully extended. (There should be
gap of approximately 3/4” in between the RESERVOIR
SHIELD and the tool body.(See gure 1)
3. Hand tighten the NOSE PIECE into the NOSE TUBE
and release the tool by squeezing the releasing trig-
ger “B” only.
Fastener Installation:
Install correct nose piece on tool (see NOSE
PIECE installation section).
1. Insert pintail of rivet in to the nose piece.
2. Then Position the rivet body in to work
piece to be fastened.
3. Hold the tool steady against the work piece
and squeeze ACTUATING TRIGGER “A”
only, until fastener is installed and rivet pin-
tail is broken* (See gure 2 below)
The AK-175 pneudraulic riveter installs fasteners by a pull and release system. Squeezing the ACTUATING
TRIGGER “A” only (Fig. 2) will actuate the tool. The tool must be actuated when installing fasteners and
changing nose pieces. After installing the fastener or changing the NOSE PIECE, the tool must be returned
to its original position. This releases the pintail if a fastener was installed. To do this, point the tool downward
and squeeze RELEASING TRIGGER “B” only (Fig. 3). See sections on NOSE PIECE INSTALLATION and
FASTENER INSTALLATION for detailed instructions.
SELECT THE PROPER NOSE PIECE FOR THE CORRECT INSTALLATION OF FASTENER AND
FUNCTION OF TOOL.
IMPORTANT NOTICE:
*The AK-175 has a 5/8 inch work travel and will set most rivets in one cycle. If the
tool reaches the end of its travel before the rivet breaks, the hydraulic system will
lug down. DO NOT continue lugging the tool. Release the tool by squeezing the
RELEASING TRIGGER “B”, regrip the rivet, squeeze the ACTUATING TRIGGER “A”
and nish the installation.
CAUTIONS:
• Before operating tool, ensure that all nose
parts have been screwed in HAND TIGHT.
• Frequently check that nose components
do not vibrate loose during operation.
