Safety Information
- Always ensure all clamps and fasteners are securely tightened before use to prevent instruments from falling.
- Do not exceed the weight capacity of the stand. Overloading can cause instability and damage.
- Place the stand on a stable, level surface to prevent tipping.
- Keep hands and fingers clear of moving parts during adjustment to avoid pinching.
- Regularly inspect the stand for any signs of wear, damage, or loose components. Do not use if damaged.
Package Contents
Verify that all components are present in the package:
- 1 x Yamaha WS-904A Heavy Duty Tom Stand (900 Series)
- 1 x 3-Hole Receiver
- Note: CLs (Tom Holders/Clamps) are not included and must be purchased separately.
Setup
Follow these steps to set up your tom stand:
- Unfold the Legs: Carefully unfold the double-braced legs of the stand until they are fully extended and stable. Ensure the stand is placed on a flat, level surface.
- Adjust Height: Loosen the height adjustment clamp on the main shaft. Extend or retract the upper section to your desired height. This stand is designed to go lower than many other Yamaha double tom stands, making it ideal for hanging floor toms. Tighten the clamp securely once the desired height is achieved.
- Attach the 3-Hole Receiver: The 3-hole receiver is designed to accept compatible tom holders or cymbal arms (not included). Insert the receiver into the top tube of the stand and secure it with the provided clamp.
- Mount Toms/Cymbals: Insert your tom holders or cymbal arms into the holes of the receiver. Adjust their positions and angles as needed, then tighten their respective clamps to secure them firmly.

Operating Instructions
Once the stand is set up and your instruments are mounted, ensure all adjustments are secure. Periodically check the stability of the stand during use, especially if making dynamic movements or playing vigorously. The heavy-duty construction and double-braced legs provide excellent stability for multiple drums and cymbals.
- Adjusting Tom/Cymbal Position: Loosen the clamp on the 3-hole receiver or the individual tom/cymbal arm to reposition. Re-tighten firmly once adjusted.
- Stability Check: Before each playing session, gently shake the stand to confirm all components are tight and the stand is stable.
Maintenance
Proper maintenance will extend the life of your tom stand:
- Cleaning: Wipe down the stand with a soft, dry cloth after each use to remove dust and fingerprints. For stubborn grime, use a slightly damp cloth and dry thoroughly. Avoid abrasive cleaners.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the moving parts, such as the height adjustment mechanism, to ensure smooth operation.
- Inspection: Regularly check all screws, bolts, and clamps for tightness. Tighten any loose fasteners to prevent wobbling or component failure. Inspect rubber feet for wear.
- Storage: When not in use, collapse the stand and store it in a dry, temperate environment to prevent rust and damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Stand is wobbly or unstable. | Legs not fully extended; clamps not tightened; uneven surface. | Ensure legs are fully spread. Tighten all clamps. Move stand to a level surface. |
| Tom/cymbal holder slips. | Clamp not tight enough; excessive weight. | Re-tighten the clamp firmly. Ensure the instrument's weight does not exceed the holder's capacity. |
| Difficulty adjusting height. | Clamp too tight; dirt/grime in the shaft; lack of lubrication. | Loosen the clamp. Clean the shaft and apply a small amount of lubricant. |
