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.

What to verify before installing a 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.

Safer operating practices (radial arm saw specific)

• 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.

Quick decision guide

Check	If you see this	Do this
Guarding	Guard cannot be installed with the dado	Do not use a dado on this setup; restore guarding
Arbor nut	Nut bottoms out or barely catches threads	Reduce stack width or do not use a dado
Cut behavior	Saw pulls hard into the work	Reduce depth per pass, improve hold-down, slow feed

Why it matters

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.

Where to look on a radial arm saw

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

What to write down (so parts match)

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

Quick ID checklist

Item on label	Why it matters	Example
Model number	Primary parts match	509346
Serial number	Production run differences	Varies
Prefix/suffix	Narrows exact configuration	Letters/numbers

Why it matters

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.

What affects lifespan most

• 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)

Maintenance that extends service life

• 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

Typical lifespan expectations

Use pattern	Typical lifespan	Notes
Light DIY	25 to 35 years	Clean storage, periodic checks
Regular homeowner	20 to 30 years	Most common range
Heavy/continuous	10 to 20 years	More wear on motor and bearings

Why it matters

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.
