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 taper sleeve socket. With the wrench provided
, tighten the nut. NOTE: Never over tighten; it may be difcult 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°.
04
TILTING THE TABLE
1. Loosen the two table lock knobs (A), located under the table at both sides of the machine
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.
1. The verticality between the table and drum has been adjusted by factory before shipment.
However, after a long period of operation, the verticality may become inaccurate.
2. To adjust the verticality, set the table to a at horizontal position. The table tilting scale should read
zero degrees.
3. Place a 90° combinative square on the table and against the drum.
4. If the table is not 90° from the drum, adjust the angle of the table by changing the height of the
resting post as shown.
5. If the table is 90° from the drum, but the scale does not read zero degree, set the scale to read
zero degree by loosening the screw on the angle indicator and setting the arrow to zero.
ADJUST THE VERTICALITY BETWEEN THE TABLE AND DRUM
05
MOUNTING SPINDLE DRUM
1. Disconnect the sander from the power source.
2. Select the proper diameter of spindle drum.
3. Clean the taper part of the spindle drum before mounting it into the spindle.
4. Use an open-end wrench to lock the spindle by holding its at surface. At the same time, use
another open-end wrench to tighten the spindle drum.
5. Do not over tighten the spindle drum or it will be causing removable problem.
! WARNING !
Disconnect the power source before removing the drum.WARNING!
Disconnect the power source before removing the drum.

SELECTION GUIDE FOR DRUM TO TABLE INSERT
This machine is furnished with 10 drums. The range of drum diameter is from 1/4” to 4”. If the
drum diameter is changed, the table insert needs to be changed to the proper size.
The table below shows which table insert to use for various drum diameters.
! WARNING !
Failure to use the correct insert with the corresponding
drum may result in injury!

1. To keep spindle sander in perfect condition, clean machine and attachments at all times.
2. Clean tapered sleeves and tapered socket before use, this will protect spindle sleeves from nicks.
3. Bent sleeves are easily straightened by placing them in the tapered socket and slipping a small
pipe over the steel shaft. Using a dial indicator check that it is in correct position.
4. Check gearbox for proper oil level (Approx. 1/4 up on sight glass).
5. We recommend that a small amount of grease be applied to table tilting screw once a month.
6. No lubrication is required for the bearings, they are permanently lubricated.
