The Dewalt DCD996 is a powerhouse in the realm of cordless drills, known for its versatility and incredible performance. However, like any tool, it can encounter issues, particularly with the choke system. In this extensive guide, we will delve into the specifics of fixing the choke in your Dewalt DCD996, ensuring you can maintain its efficiency and prolong its lifespan.
Understanding the Choke System
Before we dive into the fixing process, it’s essential to understand what the choke does in your Dewalt DCD996. The choke is an integral component of the tool, primarily controlling the airflow to the motor. A properly functioning choke ensures optimal operation, allowing your drill to perform at its best.
Failures in the choke system can lead to a range of problems, including poor performance, stalling, and increased wear on the motor. Recognizing the symptoms of a choke malfunction will help you address issues before they escalate.
Common Symptoms of a Choke Malfunction
The signs of a problematic choke can manifest in various ways. Here are some common symptoms to watch for:
- Decreased Power: If your drill seems to be losing power or struggling to penetrate materials it previously handled with ease, it might be a choke issue.
- Stalling Engine: The motor may stall unexpectedly, which can indicate that the airflow is being restricted or that there’s an issue with the choke positioning.
Preparing for the Repair
Before you begin the repair process, it’s crucial to prepare adequately. Taking the right steps now can save you time and effort later.
Gather the Necessary Tools
Having the right tools on hand is essential for a successful repair. Below is a list of tools you will need:
- Screwdriver Set: Flathead and Phillips screwdrivers are generally required to remove the casing.
- Multimeter: This will help you check for electrical failures.
- Replacement Parts: If necessary, have replacement choke components ready.
Safety Precautions
Safety should always be a top priority when working with power tools. Follow these safety tips:
- Disconnect Power: Ensure the tool is turned off and remove the battery before starting any repairs to prevent accidental starts.

Step-by-Step Guide to Fixing the Choke
Now, let’s get into the nitty-gritty of fixing the choke in your Dewalt DCD996. Following these steps carefully will guide you through the repair process.
Step 1: Remove the Drill Housing
Begin the repair by removing the drill’s casing. This will allow you to access the choke mechanism directly.
How to Remove Drill Housing
- Use a screwdriver to take out the screws holding the casing together.
- Carefully lift off the housing, being cautious not to damage any internal wiring.
Step 2: Locate the Choke:
Once the housing is off, locate the choke within the drill. The choke is typically positioned near the motor and is connected directly to the airflow system.
Step 3: Inspect the Choke Mechanism
With the choke accessible, inspect it for any visible damage or misalignment. Common problems include:
- Blockages: Look for debris obstructing the choke’s operation.
- Wear and Tear: Check for any wear that might affect its function.
If you notice any issues, you may need to replace the choke or clean the assembly thoroughly.
Step 4: Clean the Choke
If the choke appears dirty or clogged, it’s time for a cleaning.
Cleaning Process
- Use a dry cloth to wipe off any dust or debris from the choke.
- For stubborn buildup, consider using a light solvent that won’t damage the components, ensuring all residues are removed.
- Allow the choke to dry completely before reassembly.
Step 5: Test for Functionality
Before putting the housing back on, it’s a good idea to test the choke mechanism to ensure it operates smoothly.
Testing Steps
- Manually operate the choke to ensure it opens and closes without restrictions.
- Use a multimeter to check for any electrical shorts or disconnections in the wiring associated with the choke.
Step 6: Reassemble the Drill
If the choke operates smoothly, you can proceed to reassemble the drill.
Reassembly Instructions
- Carefully place the drill housing back on, ensuring that all components fit snugly.
- Replace the screws you removed earlier, tightening them to secure the housing in place.
Step 7: Final Testing
After reassembling, reconnect the power and perform a test run of your Dewalt DCD996. Monitor its performance closely to ensure the choke functions correctly.
When to Seek Professional Help
While many choke repair tasks can be handled at home, some situations may require professional intervention. These include:
- Severe Damage: If the choke or related components are extensively damaged.
- Electrical Issues: If there are persistent electrical problems beyond your expertise.
When in doubt, it’s always wise to consult with a professional technician or reach out to Dewalt customer support.
Maintaining Your Dewalt DCD996 for Longevity
Once you’ve successfully repaired the choke, it’s essential to take proactive steps to maintain your drill. Here are some tips for keeping your Dewalt DCD996 in top shape:
Regular Cleaning
Make a habit of cleaning your drill after each significant use, focusing on removing dust and debris from the motor and choke area.
Periodic Inspections
Schedule regular inspections of critical components, including the choke, to catch any slight wear or damage before it becomes a more significant issue.
Store Properly
Always store your Dewalt DCD996 in a dry place, away from moisture and extreme temperatures, to prevent rust and damage.
Conclusion
Fixing the choke of your Dewalt DCD996 doesn’t have to be a daunting task. By following these steps meticulously, you can restore your drill’s performance and enjoy the benefits of a well-maintained tool for years to come. Remember, understanding the tool’s components and being proactive about maintenance is critical in keeping your Dewalt DCD996 in prime operating condition. Happy drilling!
What is the choke function on the Dewalt DCD996?
The choke function on the Dewalt DCD996 is designed to regulate the airflow into the motor, which is particularly important when starting the tool in colder conditions or when the battery is low. When activated, the choke helps to create a richer fuel mixture, allowing the motor to start more easily. Understanding how and when to use the choke can significantly improve the tool’s performance and extend its lifespan.
If the choke is not functioning properly, you may experience difficulty in starting the tool, leading to wasted time and effort. In some cases, a malfunctioning choke can also cause the tool to stall during use. Therefore, it’s crucial to familiarize yourself with the choke mechanism and learn how to troubleshoot any issues that may arise.
How can I tell if the choke on my Dewalt DCD996 is malfunctioning?
Signs of a malfunctioning choke on your Dewalt DCD996 may include difficulty starting the tool, unexpected stalling during use, or the motor running roughly or inconsistently. If you notice that the tool requires multiple attempts to start or if it does not run smoothly, these could be indications that the choke is not operating as designed.
Additionally, if you hear unusual sounds coming from the motor or notice any significant drops in power, these could also point to choke issues. It’s essential to address these symptoms early on to prevent further damage to your tool and ensure reliable performance.
What are the steps to troubleshoot the choke on my Dewalt DCD996?
To troubleshoot the choke on your Dewalt DCD996, you first need to inspect the choke mechanism for any visible signs of damage or wear. Check for any debris that might be obstructing the choke’s movement. If you find any loose parts or corrosion, carefully clean or replace them as necessary. Make sure the choke is moving freely and not stuck in one position.
If the choke appears to be functioning, but you’re still facing issues, consider testing the battery and connections to determine if low power is causing the choking problem. Additionally, consulting the user manual for any specific guidelines related to the choke function can provide further insights into the troubleshooting process.
Can I clean the choke on my Dewalt DCD996?
Yes, cleaning the choke on your Dewalt DCD996 is a viable step in maintaining your tool. Over time, dirt, debris, and oil can accumulate around the choke mechanism, which can hinder its operation. To clean it effectively, first, ensure the tool is turned off and disconnected from any power source.
