Warnings

1. Read and understand the entire manual before assembly or operation. Do not use the tool until proper training and knowledge are obtained.
2. Keep guards in place and in working order.
3. Keep fingers and hands away from the spindle during operation. Avoid getting fingers too close to the drum.
4. Remove adjusting keys and wrenches. Develop the habit of checking that all keys and wrenches are removed before operating.
5. Keep the work area clean. Cluttered areas and benches invite accidents.
6. Do not use in dangerous environments. Avoid using power tools in damp or wet locations, or exposing them to rain.
7. Keep children and visitors away. Ensure all children and visitors maintain a safe distance from the work area.
8. Do not force the tool. It performs better and is safer when used as designed.

Spindle and Insert Storage Plates

Refer to Figure 2. Clean the insert plates and place unused inserts into Storage Plate B. Place spindles into the opposite Storage Plate A.

Figure 2: Diagram showing the sander with labels A and B pointing to storage plates.

Installing Spindles

1. Before inserting the threaded spindle into the spindle housing, ensure surfaces are clean.
2. Thread the spindle counterclockwise into the spindle housing.
3. Using the provided wrenches, tighten the spindle nut (A, Figure 3) counterclockwise while holding the spindle housing flat (B, Figure 3) with the other wrench. NOTE: Do not overtighten the spindle, as it may be difficult to remove after sanding.

Figure 3: Diagram showing spindle installation with labels A for spindle nut and B for spindle housing.

Insert Plates

1. Always use an insert plate.
2. The machine includes 2 oblong and 2 round insert plates. The oblong plates are used when the table is tilted for bevel sanding. Each plate has a notch on the outer edge for proper insertion. Refer to page 9 to determine which insert plate to use with a specific spindle.

Setup for 90°

1. Loosen both knobs (A, Figure 4) and position the table at the 0° setting.
2. Place a square (B, Figure 4) on the table, resting its long section against the sanding drum. The square should be flat against both the table and the sanding drum.
3. If table adjustment is needed, loosen both knobs and tilt the table until the square is flat against the table and sanding drum.
4. Ensure the pointer (C, Figure 4) reads 0°. If adjustment is needed, loosen the screw (D, Figure 4) and adjust to the correct position.
5. Loosen the lock nut (F, Figure 4). Adjust the 90° stop bolt (E, Figure 4) with a 13mm open wrench so it rests against the bottom of the table, then re-tighten the lock nut (F, Figure 4) with a 12mm open wrench.

Figure 4: Diagram showing table setup for 90° with labels A, B, C, D, E, F.

Setup for Bevel Sanding

1. Loosen both knobs (A, Figure 5) and adjust the table to the desired angle.
2. Tighten both knobs.

Figure 5: Diagram showing the sander with dust port labeled B.

Dust Collection

The dust port (B, Figure 5) can be connected directly to a 2" hose for dust collection. Consult your local JET distributor for dust collectors, hoses, and accessories. Optimize performance with JET dust hoods, hoses, clamps, fittings, and blast gates.

Turning the Sander On & Off

Note: Before connecting to the power source, ensure the switch is in the off position. The sander can be turned on by flipping the switch to the on position. A removable key in the switch tip can be removed when the sander is off; this prevents the dust collector from being used.

Removing Spindles

Using the provided wrenches, loosen the spindle nut (A, Figure 6) clockwise while holding the spindle housing flat (B, Figure 6) with the other wrench.

Figure 6: Diagram showing spindle nut (A) and spindle housing (B) for removal.

Changing Sanding Sleeves

1/4", 1/2" and 5/8" Sleeves

1. Loosen the clamp (A, Figure 7) with a Phillips head screwdriver.
2. Remove the sanding sleeve from the spindle shaft.
3. Install the new sleeve, ensuring the clamp is re-tightened.

1-1/2" and 2" Sleeves (optional 3")

1. Loosen the nut (B, Figure 7) with the provided wrench.
2. Remove the sanding sleeve from the spindle shaft.
3. Reverse these steps to install the new sanding sleeve.
