CALIFORNIA PROPOSITION 65
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
•lead from lead-based paints,
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, always wear NIOSH/OSHA approved, properly fitting face mask or respirator when using such tools.

ADDITIONAL SPECIFIC SAFETY RULES
Failure to follow these rules may result in serious personal injury.
1.DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury.
2.OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not thoroughly familiar with the operation of this machine.
3.FOLLOW ALL WIRING CODES and recommended electrical connections to prevent shock or electrocution.
4.NEVER TURN THE MACHINE “ON” before clearing the table/work area of all objects (tools, scraps of wood, etc.).
5.NEVER TURN THE MACHINE “ON” with the workpiece contacting the abrasive surface.
6.SECURE THE MACHINE to a supporting surface. Vibration can cause the machine to slide, walk, or tip over.
7.REPLACE SLEEVES WHEN WORN OR DAMAGED. A torn or damaged sleeve could be unexpectedly expelled from the machine if not replaced
8.PROPERLY SECURE SANDING DRUM on spindle before operating.
9.DO NOT USE THE MACHINE for wet sanding applications.
10.CLEAN THE MACHINE and dust collector thoroughly when processing different types of workpieces (wood, steel, or aluminum). Combining wood and metal dust can create an explosion or fire hazard.
11.TO REDUCE THE RISK OF FIRE, do not sand or polish magnesium.
12.HOLD WORKPIECE FIRMLY ON THE SANDER TABLE. To prevent loss of control use a solid grip.
13.INSPECT MATERIALS FOR DEFECTS. Knots and splinters can be thrown from the machine with great force. Make sure defective materials are not used on this spindle sander.
14.FOREIGN OBJECTS SUCH AS NAILS AND STAPLES should be removed before sanding.
15.AVOID AWKWARD OPERATIONS AND HAND POSITIONS. A sudden slip could cause a hand to contact the abrasive sleeve.
16.KEEP TABLE INSERT IN PLACE. Use correctly sized table insert for each sanding sleeve to reduce risk of fingers being pinched or material being pulled down.
17.ALWAYS FEED WORKPIECE AGAINST the direction of the sanding belt rotation.
18.DO NOT SAND very small or very thin workpieces that cannot be safely controlled. Loss of control of the workpiece can result in injury.
19.TO MAINTAIN CONTROL, properly support long or wide work-pieces.
20.NEVER PERFORM LAYOUT, ASSEMBLY, OR SET-UP WORK on the table/work area when the machine is running. A sudden slip could cause a hand to move into the abrasive surface.
21.TURN THE MACHINE “OFF”, disconnect the machine from the power source, and clean the table/work area before leaving the machine. LOCK THE SWITCH IN THE “OFF” POSITION to prevent unauthorized use.
22.ADDITIONAL INFORMATION regarding the safe and proper operation of power tools (i.e. a safety video) is available from the Power Tool Institute, 1300 Sumner Avenue, Cleveland, OH 44115-2851 (www.powertoolinstitute.com). Information is also available from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201.

POWER CONNECTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.
Do not expose the machine to rain or operate the machine in damp locations.
MOTOR SPECIFICATIONS
Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
This machine must be grounded while in use to protect the operator from electric shock.
1.All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This machine is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instruction are not completely understood, or if in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
2.Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig. B may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
In all cases, make certain that the receptacle in question is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

EXTENSION CORDS
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

3.Slide that abrasive sleeve (C) Figs. 5 and 6 over the matching sanding drum (D) Figs. 5 and 6. Position this assembly on the spindle adapter. Place the matching washer (A) Fig. 5 (largest, but not larger than the rubber drum) on top of the assembly and fasten it with a 5/16" screw (E) Fig. 5, using the socket wrench (F) Fig. 7.
NOTE: Turn the screw (E) Fig. 5 counter-clockwise to tighten and clockwise to loosen.
4.Place the table insert (G) Figs. 7 & 8 over the abrasive sleeve (C) and in the cut-out on the table. NOTE: Arrows on the table insert indicate the top surface.
5.Use the compartments (H) Fig. 8 on the sides of the sander for storing workpieces or accessories.
ATTACHING THE DUST BAG
To attach the dust bag (B) Fig. 10 to the 1-1/2"dust chute (A) Fig. 9, squeeze the spring clamp on the dust bag and slide it over the dust chute. Release the clamp.

OPERATION
OPERATIONAL CONTROLS AND ADJUSTMENTS
STARTING AND STOPPING THE SANDER
The on/off switch (A) Fig. 12 is located on the sander |
|
base. To turn the sander “ON”, move the switch up to |
|
the “ON” position. To turn the sander “OFF”, move the |
|
switch down to the “OFF” position. |
A |
|
FIG. 11
LOCKING THE SWITCH IN THE “OFF” POSITION
IMPORTANT: When the machine is not in use, the switch should be locked in the "OFF" position to prevent unauthorized use. To lock the machine, grasp the switch toggle (B) and pull it out of the switch (Fig. 13). With the switch toggle (B) removed, the switch will not operate. However, should the switch toggle be removed while the sander is running, the machine can be turned "OFF," but cannot be restarted without re-inserting the switch toggle (B).
ADJUSTING THE SPINDLE ASSEMBLY
If excessive play develops in the spindle assembly, or if noise level increases after extended use, adjust the spindle assembly.

MACHINE USE |
|
Sanding inside curves is illustrated in Fig. 16. |
|
IMPORTANT: Always sand against the rotation of the |
|
sanding drum. |
|
The oscillating action of the sanding drum minimizes |
|
score marks and prevents clogging of the sanding |
|
drum, providing faster, smoother sanding and increasing |
|
the life of the sanding sleeve. |
