PJL Optima 2 Plus Instructions For Use

INSTRUCTIONS FOR USE
Please follow these safety rules when using the Optima 2 Plus
A. Wear Eye Protection! It takes only one small piece of flying debris to cause
serious eye injury.
B. Keep this and all power tools out of the reach of children.
C. Wear a dust mask, or use a dust collector, approved for the type of material you
are grinding. Many materials can be dangerous to breathe when they are ground
into small particles.
INSTRUCTIONS
1. HANDPIECE SECTION OUTLINE:
The handpiece is divided into six sections. From Front to rear they are: Collet,
Nose Piece, Collet "Release/Secure" mechanism, motor, and cord cap. The
collet mechanism has an "R <----> S" embossed on it. Keep these different
"sections" in mind when reading the rest of these instructions. DO NOT TRY
TO REMOVE THE "NOSE PIECE" SECTION OF THE HANDPIECE!

2. CHANGING BITS:
To Release a bit, hold the handpiece motor section, and turn the Secure/Release
section toward the "R" about 1/4 turn, until it locks open (you should hear a
distinctive "click"), and exchange bits. Then turn the collet/release section back
in the "S" direction to Secure the bit. Be sure that your bits are clean, dry, rust,
and dirt free before inserting into collet, to ensure clean operation of collets.
NEVER turn the collet/release section while the unit is in operation! Do Not use
oversized bits. If it does not fit into the collet, do not use it!
3. COLLET EXTRACTION AND INSTALLATION:
To extract a collet from your handpiece, twist the collet/release section toward
"R" about 1/4 turn, until it locks into place. Use the triangular hole in collet
wrench to unscrew the collet counterclockwise (always keep a bit, or "blank bit"
of the proper size, in the collet while doing this to prevent damage to the collet).
Select another collet, ensuring that its threads are clean and dirt free, insert into
collet hole, put a bit or blank shank into collet, and screw it in clockwise by hand.
Tighten with collet wrench until you feel some resistance, twist the collet/release
section toward "S" (Secure bit) again before operating. You should tighten
collets fully with collet wrench, or your handpiece may not operate properly. Do
not over tighten, as you can strip the collet threads or even break the collet.

4. TO REVERSE DIRECTION:
When changing the handpiece rotational direction, let the tool stop rotating
COMPLETELY (switch in center, knob at low or off position) before switching
it to other direction. This will prolong the life of your motor handpiece tool
greatly.
5. TO TURN OFF MACHINE:
Rotate the speed control dial fully counterclockwise until you hear a click, and
the green light is off. Or, on the Ultima, turn the Burn/Grind switch to the center
position.
6: TO CHANGE BRUSHES
Unscrew the cord cap, and remove cord. On either side of the black plastic
assembly on the back, you will see indentations with copper colored strips with a
silver colored solder ball on it, being held in by a small Phillips head screw. Use
a small Phillips head screw driver to remove those screws (don't loose them),
and remove each brush being careful that the underlying spring tension cord
connector is not lost. Do one side at a time, so that you know how it is
reassembled. Attach cord when finished, screw cord cap back on. Run the
handpiece in reverse, and then forward at high speed (fifteen minutes each
direction) to "break in" the brushes before using handpiece again (always be
sure that the motor comes to a complete stop, and that your speed control dial is
set to low before reversing motor direction).
7. The Optima 2 Handpiece uses precision ball bearings.
DO NOT OIL THEM OR THE COLLETS!, as that will ruin the special lubricant
in them, and cause them to quickly fail (doing that will also void your warranty)!
DO NOT use a compressed air tool to clean out/off the handpiece or collet hole,
as this will drive dust into the bearing, and blow the oil out of them.
8. NOTE:
The Optima 2 includes a built-in resettable circuit breaker that will cut off power
to the handpiece if it is over worked or abused for 5 seconds or more. If this
happens, turn off the machine (see #5) for 30 seconds, then turn back on. Go
easier on the tool if this happens!
WARRANTY: The Optima 2 Plus handpiece and cord is warranted against
manufacturing defects and operational failure for 1 year from date of purchase
(copy of proof of purchase date, or receipt required). The Optima 2 Plus power
supply is warranted against Manufacturer defects for life. If any repairs are
needed, they will be performed quickly right here at PJL Enterprises. Please call
before sending it in for repair so that we can diagnose the problem. Sometimes
you don't need to ship the whole unit, which could save you some money. You
should contact PJL about repair diagnostics, after which you'll be given a
recommendation on what to ship, and how to ship it for fastest service possible.
DISASSEMBLY OF THE NOSE PIECE, OR POWER SUPPLY, WILL VOID
YOUR WARRANTY! The collets, brushes, and cord are the only user serviceable
parts.
