SAFETY RULES
Read carefully before operating the machine
1. Learn the machine’s applications
particular to this machine. Follow available safety instructions and safety rules carefully.
2. Keep working area clean and be sure adequate lighting is available.
3. Do not wear loose clothing, gloves, bracelets, necklaces, or ornament. Wear face, eye, ear,
respiratory and body protection devices, as indicated for the operation or environment.
4. Keep hands well away from sanding spindle and all moving parts. Do not clear sawdust
away with hands. Use a brush.
5. Make sure the spindles are moving at operation speed before sanding.
6. Do not push the sanding spindles to hard. The spindles will perform better and be safer
working at the rate for which it was designed.

unintentionally contacted.
12. Be sure sanding spindles are securely locked in the machine.
13. Use suitable support if stock does not have a flat surface.
14. Keep guards in place and in working order. If a guard must be removed for maintenance or
cleaning make sure it is properly attached before using the tool again.
15. Be sure that adjusting wrenches have been removed before turning power on.
16. Only use accessories designed for the machine. Use of accessories not recommended by
may result in a risk of injury.
17. Make sure tool is properly grounded. If tool is equipped with three-prong plug, it should be
plugged into a three-pole electrical receptacle. Never remove the third prong.

INSTRUCTIONS FOR OPERATIONS
1. Select spindle that is smaller than the curve to be sanded.
2. Use an insert plate that comes closest to the spindle without touching it.
3. Make sure that spindle is properly positioned in t aper sleeve socket. With the wrench provided
, tighten the nut. NOTE: Never over tighten; it may be difficult to remove the spindle later.
4. When table is set at a 90° angle, sanding may be done from any corner, or location on table
around spindle.
5. When table is positioned at any angle other than 90°, it is necessary to position the work piece
over the centerline, as shown on table surface.
6. Always lock the table with the hand nut when setting at any angle, also to prevent movement
lock the tilting gear shaft.
7. Always loosen both table lock and tilting gear lock before changing the angle position of the
table. Never force the table if it does not tilt easily, reason may be that the locks are still
engaged. Never attempt to over ride the stop locks, this will cause damage to the tilting
performance.
8. A backing board is recommended when sanding thin pieces of metal or any other material. A
backing board can be easily constructed by using a piece of wood the length of the table,
pushing it into the spindle until a half circle is formed. Clamp each end of the board to the table
and proceed to sand the thin material.
9. Before leaving the machine remove any particles or pieces left over, make sure the table in
90°.
TILTING THE TABLE
Loosen the two table lock knobs (A), located under the table at both sides of the machine
1.
2. Tilt the table forward to the desired angle with your hands.
3. An angle scale is provided at the right side of the trunnion to indicate the degree of table tilt.
4. Tighten the two table lock knobs securely after the table degree has been adjusted.

another open-end wrench to tighten the spindle drum.
5. Do not over tighten the spindle drum or it will be causing removable problem.
