One common issue with the Dewalt DW788 scroll saw is incorrect blade tension, which can lead to poor cuts and frequent blade breakage.
Ensuring the blade is neither too tight nor too loose is essential for smooth operation and precision work.
Cause:
Improper adjustment of the tension knob or wear and tear in the tensioning mechanism can result in unstable blade performance.
Fix:
Regularly check and adjust the tension knob to the recommended settings for your blade type.
If the problem persists, inspect the tensioning mechanism and replace any worn or damaged parts to restore proper functionality.
2. Power Loss
Power loss is a common issue with the Dewalt DW788 scroll saw that can disrupt your work.
Causes

- Faulty power switch
- Motor overheating or wear and tear
Fixes
- Inspect and replace a damaged power cord.
- Check the power switch for faults and replace if necessary.
- Clean the motor vents and allow it to cool; replace the motor if it’s beyond repair.
3. Excess Vibration
Excess vibration is a common issue with the Dewalt DW788 scroll saw, making precise cuts challenging and reducing overall performance.
This problem can stem from loose components, an uneven surface, or wear and tear over time.
Addressing this issue promptly ensures smoother operation and extends the lifespan of your saw.
Causes
- Loose screws or bolts in the machine.
- Uneven or unstable workbench surface.
- Worn-out bearings or motor issues.
Fixes

6. Motor Overheating
One common issue with the Dewalt DW788 Scroll Saw is motor overheating.
This can happen when the saw is used for extended periods without breaks or if there’s a problem with airflow.
Overheating not only affects performance but can also lead to long-term damage if not addressed promptly. Identifying the cause and addressing it quickly is key to keeping your saw running smoothly.
Causes
- Prolonged use without adequate rest periods.
- Dust buildup restricting airflow to the motor.
- Poor lubrication or worn-out internal components.
Fixes
- Allow the saw to cool down after long sessions.

- Ensure proper lubrication and check for worn parts, replacing them as needed.
7. Dust Build-Up
Dust build-up is a common issue with the Dewalt DW788 scroll saw, often affecting its performance over time.
When dust accumulates, it can clog moving parts and reduce efficiency, making cuts less precise. This issue can also lead to overheating if not addressed promptly.
Cause
The main cause of dust build-up is prolonged use without proper cleaning.
Sawdust can collect in hard-to-reach areas, especially around the blade and motor housing.
Fixes
To fix this, regularly clean the scroll saw using compressed air or a brush to remove debris.
Additionally, consider attaching a dust collection system to minimize build-up during use. Routine maintenance will help keep your saw running smoothly and extend its lifespan.
8. Switch Failure
One common issue with the Dewalt DW788 scroll saw is switch failure, where the saw either won’t turn on or shuts off unexpectedly.
Causes:
- Dust or debris clogging the switch
- Worn-out or faulty switch components
Fixes:
- Clean the switch area thoroughly to remove dust or residue.
- If cleaning doesn’t work, replace the faulty switch with a new one, ensuring compatibility with the DW788 model.
9. Loose Screws
Loose screws are a common issue with the Dewalt DW788 scroll saw and can lead to unstable performance or excessive vibration during operation.
Causes
- Vibrations from extended use can loosen screws over time.
- Improper assembly or failure to securely tighten screws initially.
Fixes
- Inspect all screws regularly and tighten them using the correct tools.
- Apply a thread locker to prevent screws from loosening again.
10. Belt Slipping
If your Dewalt DW788 scroll saw is experiencing belt slipping, it can lead to uneven performance and reduced efficiency.
Causes:
- Worn-Out Belt: Over time, the belt may degrade or lose its grip.
- Improper Tension: Incorrect belt tension can cause it to slip during operation.
Fixes:
