Emerson 509346 guard kit Parts

Yes, a radial arm saw can cut dados, but you only do it when the saw is explicitly set up to accept a dado stack and you can keep proper guarding and work control in place. For the Emerson model 509346, confirm your specific saw’s arbor, flange, and guard clearance before installing any dado set.

• Arbor diameter match: the dado set bore must match the saw’s arbor.
• Arbor length and nut engagement: the arbor nut must fully tighten with several threads engaged.
• Flange and washer fit: the stack must clamp flat and evenly with no wobble.
• Guard and anti-kickback compatibility: you must be able to reinstall the guard and any anti-kickback features after the dado is mounted.
• Clearance at full travel: the wider cutter must not contact the guard, yoke, or table hardware through the full stroke.

• Unplug the saw before changing blades or adjusting the guard.
• Use a sharp, complete stacked dado set; do not run damaged blades or mismatched chippers.
• Make multiple shallow passes instead of one deep, full-width pass.
• Keep the work tight to the fence and table; use hold-downs and stop blocks when possible.
• Maintain a controlled feed; if the saw starts to self-feed, stop the cut and reset your setup.

A dado stack increases cutting width and load. On a radial arm saw, that can increase self-feeding and kickback risk, so compatibility and guarding are as important as the cut itself.

For the Emerson 509346 radial arm saw guard kit, the model number is typically printed on an ID label or stamped plate on the saw’s frame or arm assembly. We use that exact model number to match the correct diagrams and replacement parts.

Check these common locations first:

• The back or side of the saw’s column (vertical support)
• The arm casting near the carriage travel area
• The motor housing or motor mounting yoke
• The base frame or table support structure
• Under the table surface or on the front edge of the base

Record the full identification details, not just “509346”:

• Model number (for example, 509346)
• Serial number
• Any prefix/suffix characters on the tag
• Electrical rating (volts/amps), if shown

Radial arm saws and guard kits can change across production runs; using the complete model and serial information prevents ordering the wrong guard components, hardware, or mounting pieces.

The average lifespan of an Emerson 509346 radial arm saw (and its guard kit components) is 20 to 30 years with normal homeowner use and basic maintenance. Many units last longer when kept clean, aligned, and used with a properly functioning blade guard.

• Dust buildup in the motor and switch area
• Worn bearings, brushes (if equipped), or power cord damage
• Misalignment of the arm, yoke, or fence causing strain and poor cuts
• Missing, cracked, or binding guard components
• Storage conditions (humidity leads to corrosion)

• Vacuum dust from vents and the arm/column after use
• Inspect the power cord and plug; replace if cracked or loose
• Verify the blade guard moves freely and returns to its resting position
• Check fasteners for tightness and keep the table/fence secure
• Confirm smooth carriage travel; address binding promptly

A radial arm saw can keep running for decades, but safety and cut quality depend on the condition of wear items (cord, switch, bearings) and the guard kit. If the guard does not operate smoothly, address that before continued use.
