ASSEMBLY & INSTALLATION
Numbered references in parenthesis (#1) refer to the included Parts List.
INSTALL AIR COUPLER PLUG
Prepare a standard 1/4 in. NPT male air coupler plug (sold separately) for use with
your tool.
1. Wrap the external threads of the male coupler plug with sealant tape.
a. Wrap tape in a clockwise direction so it will not unravel.
b. Do not tape all the threads. Leave several leading threads unwrapped for
easier alignment.
2. Screw the coupler plug into the tool's air inlet and tighten with a wrench until snug.
3. Run the compressor at a low volume and check the connection for air leaks. Do
not use the tool until all air leaks are repaired or the faulty component is replaced.
IMPORTANT! Vibration may cause failure if a quick coupler is connected directly
to the air tool. To overcome this, connect a leader hose to the tool. A quick
coupler may then be used to connect the leader hose to the air line hose.
ASSEMBLING THE NEEDLE HOLDER
1. Insert the needles (Fig. 1-4) through the holes of the needle holder (Fig. 1-3).
Each needle’s head should fit snugly into
the holder when inserted through the
correct side.
2. Slide the spring (Fig. 1-2) over the needles.
3. Slide the needle assembly into the needle
tube (Fig. 1-1) until the spring rests against
the front of the tube. Push any wayward
needles down into the holder.
