Setup and Assembly
Unpacking
Carefully remove all components from the packaging. Inspect for any shipping damage. Retain packaging for future transport or storage.
Mounting the Jig Saw
The Atlas 24-inch Jig Saw should be securely mounted to a sturdy workbench. Use appropriate bolts and washers through the mounting holes provided in the base of the machine. Ensure the workbench is stable and level.
Blade Installation
- Ensure the power cord is disconnected.
- Loosen the blade tension knob.
- Insert the blade into the lower blade holder, ensuring it is seated correctly.
- Guide the blade through the table insert and into the upper blade holder.
- Tighten the upper blade holder screw.
- Adjust the blade tension until the blade is taut but not overly stressed. A slight deflection when pressed gently is ideal.
Table Tilt Adjustment
The saw table can be tilted for bevel cuts. Loosen the table locking knob, adjust the table to the desired angle using the angle scale, and then securely tighten the knob.
Operating Instructions
Before Starting
- Verify the blade is correctly installed and tensioned.
- Ensure the workpiece is free of nails, screws, or other foreign objects.
- Adjust the hold-down foot to lightly rest on the workpiece.
- Connect the saw to a grounded power outlet.
Making a Cut
- Place the workpiece firmly against the table.
- Turn on the jig saw using the power switch.
- Allow the saw to reach full speed before beginning the cut.
- Feed the workpiece slowly and steadily into the blade. Do not force the cut.
- Maintain a firm grip on the workpiece, keeping hands clear of the blade path.
- Upon completion of the cut, turn off the saw and wait for the blade to stop completely before removing the workpiece.
Internal Cuts
For internal cuts, drill a pilot hole in the workpiece large enough to insert the blade. Disconnect power, remove the blade, thread it through the pilot hole, and re-install it before proceeding with the cut.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your Atlas Jig Saw. Always disconnect power before performing any maintenance.
- Cleaning: Keep the saw clean and free of dust and debris. Use a vacuum cleaner or compressed air.
- Blade Replacement: Replace dull or damaged blades promptly. Refer to the "Blade Installation" section for proper procedure.
- Lubrication: Periodically apply a light machine oil to moving parts as indicated in the parts diagram (refer to original manual for specific points).
- Inspection: Regularly inspect the power cord for damage, and check all fasteners for tightness.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Saw does not start | No power; faulty switch; tripped circuit breaker | Check power connection; test switch; reset breaker |
| Blade breaks frequently | Incorrect blade tension; wrong blade type for material; forcing cut | Adjust blade tension; use appropriate blade; reduce feed pressure |
| Inaccurate cuts | Loose blade; worn blade; table not square | Tighten blade; replace blade; adjust table squareness |
| Excessive vibration | Loose mounting bolts; unbalanced blade; worn bearings | Tighten mounting bolts; replace blade; consult service technician |
