ASSEMBLY & INSTALLATION
INSTALLING THE NEEDLE
1.
Hold the air engraving pen at an upward angle to avoid dropping internal
components.
2.
Remove the o-ring from the needle guide and set aside.
3.
Unscrew the nose from the body and set aside.
4.
Remove the needle from the body. Transfer the spring to the new needle and
store the old needle.
5.
Insert the new needle plat first into the upturned body until it is pressed against
the internal valve seat.
6.
insert the needle through the needle guide and let it drop into place.
7.
Place the nose over the needle guide and screw it into place until hand-tight.
8.
Push the o-ring onto the needle guide until it covers the gap between the nose
and needle guide. The small exhaust airways should still be uncovered.
INSTALL AIR COUPLER PLUG
Prepare a standard 1/4 in. NPT coupler plug (sold separately) for use with your tool.
1.
Wrap the external threads of the 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.
OPERATION
NOTICE! The engraver will build up heat during continuous operation. Do not
operate the engraver continuously for more than five minutes at a time. After
five minutes of continuous operation, the tool must be turned OFF and allowed
to cool down for at least five minutes.
1.
Draw a pattern on the material with a marker to make it easier to follow with the
engraver tool.
2.
Hold the throttle valve and turn the air engraving pen’s body. This will cause the
needle to vibrate. Increase or decrease the speed by twisting the body left or
right.
3.
Hold at an angle and lightly contact the tip to the workpiece.
4.
Move slowly with deliberation and allow the tool to cut the material. Do not force
the tool. You may want to brace the hand holding the tool with your other hand.
