16 Chuk/Changer Instruction
OPERATION AND CARE INSTRUCTIONS
CAUTION
Do not attempt to operate Chuk/Changer unless it is properly installed on lathe.
Never oil or use solvents of any kind on Chuk/Changer
Never close collet without a tool (chuck,burr, etc) in the collet. Allow clutch spring to engage clutch.
(Never push up on handle or let handle snap up.)
Do not remove or attempt to defeat the purpose of the safety strap.
OPERATION
Normal running position, handle 9:15 o’clock to 10:30 o’clock.
To disengage clutch, bring handle down to 8:00 o’clock position, counter-clockwise.
To apply brake, bring handle down to approximately 7:00 o’clock position, counter-clockwise.
(Note: Brake position is used for changing arbor bands, buffing wheels, etc.) To open collet, bring
handle straight down to 6:00 o’clock position. Tools (chucks) burrs, etc., may be changed while
handle is in straight down (6:00 o’clock) position.
USE OF 3/32” DIAMETER SHANk TOOLS IN CHUk/CHANGER
1. With handle straight down, insert tool in inner collet to desired depth.
2. Move handle clockwise to approximately 8:00 o’clock position.
Remove hand from tool and allow clutch spring to return handle to running position.
3. Never push up on handle.
USE OF 1/4” DIAMETER SHANk TOOLS IN CHUk/CHANGER
1. With handle straight down, insert chuck shank into outer collet.
Note: The inner collet will be pushed back inside Chuk/Changer
2. While holding tool in collet, move handle clockwise to approximately 8:00 o’clock position.
3. Remove hand from tool and allow clutch spring to return handle to running position.
4. Never push up on handle.
CLEAN COLLETS EVERY 30 DAYS
1. With lathe switch OFF and clutch handle straight down, (collets open) unscrew otuer collet
(part No.5) with collet wrench (Part No.8) Unscrew counter-clockwise.
2. Remove both inner and outer collets
3. Thoroughly clean collet, you may use solvent to clean collets, however, you must remove all
traces of solvent before replacing.
4. Thoroughly clean collet body hole by using pipe cleaner or small cloth on end of instrument.
Do not use any solvents in this hole. Put a thin film of grease on outside of both collets. (This
purpose of this cleaning is to lubricate and prevent rust. Failure to clean and grease will cause
collets to slip and stick.)
5. Replace collets, with collet wrench, scrwing clockwise.
REPLACING WORN COLLETS
When tools (chucks) burrs, etc. begin to slip, collets should be replaced.* When replacing collets,
always use the shortest possible stop. Part No.3, that will still allow the tools to slip into the master
collet. WE recommend that you keep spare collets Part No.1 and
No. 5 and a set of stops, Part No.3S on hand at all times.
HOW TO REMOVE A STUCk COLLET
A collet may get rusty or dirty and stick if it is not cleaned and greased regularly, or it may stick if
collet is closed without a tool in the collet. Open collet by moving handle staright down (collet open).
Put collet wrench in collet and tap lightly on the end of the collet wrench and at the same time
attempt to unscrew the collet. If this does not loosen the collet, with the handle in the same position,
remove the four screws that hold the chuck on the adapter and remove chuck. Caution: be sure not
to move the handle during this procedure. See instructions under removing chuck from lathe. Grasp
the steel clutch plate to keep it from turning while you remove the collet.
*However, make certain collets have been properly cleaned. Dirty collets may also cause chuck slippage.
