5. Insert the replacement collet into the spindle
and replace the collet nut by turning it clockwise
while holding the spindle lock button down.
Note: Do not tighten the collet nut without an accessory
installed in the collet. You will damage the collet.
Installing accessories (Fig. D)
1. Turn the switch OFF and disconnect the tool from
the power source.
2. Depress the spindle lock button (2) and slowly turn
the collet nut (3) until the spindle lock button locks
the spindle (Fig. D).
3. While holding the spindle lock button down,
turn the collet nut counter- clockwise until the collet
is loose inside the collet nut.
4. Insert accessory (8) into collet.
Notes:
a. Make sure the correct collet is used for
the accessory. If collet is too large, replace
the collet with the next smaller size.
b. Insert accessory at least 3/4" into the collet.
5. Press the spindle lock button and engage it in
the spindle. While holding the spindle lock button
down, hand-tighten the collet by turning it clockwise.
Note: Do not use pliers to tighten the collet nut. Use
the small wrench supplied. Over tightening will cause
damage to the tool.
6. Pull on the accessory to ensure it is securely in place.
Connecting the flexible shaft to the tool (Fig. E)
The flexible shaft is designed to facilitate working in confined
spaces where otherwise using the rotary tool may be awkward.
Warning! Never bend the flexible shaft with a radius
of less than 6" when operating. Store the flexible shaft
in the designated compartment of the blow molded case
when not in use.
1. Remove umbrella nut (10) from the tool by turning it
counter-clockwise.
2. Before replacing collet nut, check to make sure
the 1/8" collet is installed in the motor shaft.
Notes:
a) To change collet, see Fig. C.
b) Do not tighten collet nut on collet.
3. Pull flexible shaft inner cable (11) out of the outer
casing (12) about 2".
4. Insert flexible shaft inner cable into the collet until
the stopper (13) touches the collet.
5. Tighten collet nut (see Fig. D).
Note: Do not use pliers to tighten the collet nut.
Use the small wrench supplied. Over tightening will
cause damage to the tool.
Note: Slide flexible shaft outer casing over the collet nut
until casing rests against the threaded section (14).
Note: DO NOT force the outer casing. If the outer
casing will not easily slide over the inner cable, turn
the collet on the opposite end of the flexible shaft until
the resistance of the inner cable ceases.
6. This should allow the outer casing to slide over
the inner cable, and then allow the casing to rest
against the threaded section.
7. Screw flexible shaft head nut (15) onto the threaded
section by turning it clockwise.
Note: Only finger-tighten spindle nut. Do not use
pliers or wrench.
Changing the collet and accessories
in the flexible shaft (Fig. F)
To change the collet or to install an accessory in the
flexible shaft, follow "Changing the collet" and
"Installing accessories". To lock the shaft, pull back on
the flexible shaft grip (16) and rotate the collet until the shaft
grip locks the shaft (see Fig. F). The flexible shaft grip
will return to its normal position when not being held in
the lock position.
Notes:
a) Do not attempt to loosen or tighten the collet
without locking the shaft as noted above.
Damage to the flexible shaft will result.
b) Do not over tighten collet nut.
Warning! When using the flexible shaft, only hold
the shaft by the grip. Do not force the cutting accessory
so as to avoid damaging the flexible shaft.
Assembling and installing the stand (Fig. G, H, I)
The C-clamp that holds the hang bar rod can be mounted
either horizontally or vertically (a) and (b).
1. Clamp the C-clamp (18) onto a work table (horizontal
surface) or other appropriate vertical surface by tightening
the clamp screw (17) clockwise (see, (a) and (b)).
Note: Do not over tighten to avoid breaking the clamp.
2. Thread screw (19) in the bottom of the hang bar rod (20)
into the appropriate mounting hole (21) in the C-clamp
(Fig. H).
Note: Do not over tighten. Hand-tighten only.
3. Loosen hang bar sections (22) by turning them
counter-clockwise.
4. Pull out each hang bar section approximately 5"
and lock into place by turning them clockwise.
Note: Do not over tighten. You will damage the locking
mechanism.
5. Insert the rotary tool hanger (23) into the top
of the hang bar rod.
6. Using the hang loop on the rotary tool (24) hang rotary
tool from the stand (Fig. I).
