How to Oil Hedge Trimmer

Have you been out doing yard work and noticed your hedge trimmer is struggling to cut through branches like it used to? Frustrated by the effort it now takes to tame those overgrown hedges into neat lines? Worry not. A lack of lubrication may be the culprit behind your old trusty trimmer’s lack of cutting power. A simple tune-up involving cleaning and oiling the parts can restore this hard-working tool to its former glory.

How to Oil Hedge Trimmer

Hedge trimmer maintenance should be done regularly, but it is essential to oil before and after each use. This little step can keep your trimmer running smoothly for years to come.

In this post on how to oil hedge trimmer, I’ll walk through the basic steps to disassemble, clean, and re-oil your hedge trimmer so it’s slicing through bush and briar with ease once more.

What Will You Need?

Before we dive into the oiling process, gather some essential supplies:

  • Cleaning rag
  • Wire brush
  • Mineral oil or multipurpose lubricant

Once these items are at hand, you’re ready to begin!

10 Easy Steps on How to Oil Hedge Trimmer

Step 1: Cleanup Time

A good cleaning is necessary before applying any oil. Start by carefully trimming away any visible debris from your hedge trimmer blades and body with a clean rag. For stubborn patches of dirt or plant residue, use a wire brush to remove it gently. This step will ensure the oil can thoroughly reach all parts of the hedge trimmer and work its magic effectively.

Step 2: Disassembling the Hedge Trimmer

Safety first! Before disassembling, ensure the hedge trimmer is switched off and unplugged. The last thing we need is an unexpected start-up during the cleaning process. Once it’s safe, start by removing the screws that hold the blades together. This will separate the two halves of the blades, making it easier for you to clean and oil them thoroughly.

Ensure the Hedge Trimmer is Switched Off

Step 3: Cleaning the Blades

With the hedge trimmer disassembled, now is the time to give the blades a deep clean. Scrub off any remaining dirt or plant residue from the blades using your wire brush. Pay close attention to the nooks and crannies, as debris often accumulates in these areas. After scrubbing, wipe the blades clean with the rag. Ensure the blades are completely dry before proceeding to the next step to prevent rust.

Step 4: Applying the Oil

Now that your hedge trimmer’s blades are clean and dry, it’s time to apply the oil. Pour some mineral oil or multipurpose lubricant onto a cloth and gently wipe it along the edge of the blades. Cover both sides of each blade thoroughly to achieve a smooth, even coverage. The oil lubricates the blades and provides a protective layer against rust and corrosion. Once the blades are fully oiled, leave them to sit for a few minutes to allow the oil to penetrate the metal.

Step 5: Reassembling the Hedge Trimmer

After the oil has had time to soak into the blades, it’s time to put your hedge trimmer back together. Start by aligning the two halves of the blades. Make sure that they fit correctly into their original position. Then, begin to carefully replace each screw in the order they were removed.

Ensure each screw is tightened securely, but avoid over-tightening as this may cause damage to the blades. Once all screws are back in place, double-check your work to make sure everything is back where it should be. Now, your hedge trimmer should be ready to make short work of those unruly hedges again.

Step 6: Testing the Trimmer

Now that your trimmer is reassembled and freshly-oiled, it’s time to test it. Carefully test your hedge trimmer using a small, manageable branch or bush. You should notice a significant improvement in the ease of cutting and overall performance. If it’s still not running smoothly, you may need to disassemble it again and add more oil. Getting just the right amount of lubrication is essential for optimal performance.

Carefully Test Your Hedge Trimmer

Step 7: Regular Maintenance

To keep your hedge trimmer running smoothly, making oiling and cleaning a routine part of your maintenance is essential. Regularly check your hedge trimmer for visible signs of wear or damage. Clean and oil it after each use to prevent the buildup of dirt and plant residue that can hinder its performance. This regular upkeep will not only ensure your trimmer stays in top condition, but it will also extend its lifespan, saving you from costly replacements.

Step 8: Storing the Hedge Trimmer

After you have done all the hard work of cleaning, oiling, and maintaining your hedge trimmer, it’s time to store it properly. Avoid leaving it out in the open or in damp, humid areas as this can promote rust and corrosion. Instead, find a dry, secure location where it can be safely stored away from the elements. Cover the blades with a protective sheath to prevent any accidental cuts or scrapes. With the right storage conditions, your hedge trimmer will be ready and in perfect condition for the next time you need it.

Step 9: Regular Inspection

In addition to regular cleaning and oiling, it’s advisable to conduct a thorough inspection of your hedge trimmer at least once a year or more frequently if it’s heavily used. Pay particular attention to the condition of the blades. Look out for any signs of damage, such as cracks, bends, or dull spots on the cutting edges.

These can impair the machine’s performance and even make it dangerous to use. If you notice any damage or wear that goes beyond normal use, consider getting the blades professionally sharpened or replaced. Regular inspections will help you keep your hedge trimmer in optimal condition, ensuring safe and efficient operation.

Step 10: Professional Servicing

While maintaining your hedge trimmer at home is essential, having it professionally serviced occasionally is also beneficial, especially if it’s used frequently or heavily. Professional servicing can help identify any underlying issues that may not be immediately apparent, ensuring your hedge trimmer operates at its peak efficiency. Plus, skilled technicians can perform intricate tasks like fine-tuning the engine or replacing worn parts that may be challenging to do at home.

By following these straightforward steps, you can efficiently and effectively maintain your hedge trimmer to keep it running like new for years.

5 Additional Tips and Tricks

  1. Use Quality Oil: Always use high-quality lubricating oil for your hedge trimmer. It might be tempting to save a few bucks on cheaper alternatives, but a premium oil will provide better lubrication and protection, ensuring your machine’s longevity.
  2. Wear Safety Gear: Safety should always be your top priority. When operating the hedge trimmer, ensure you wear the necessary safety gear. This includes gloves, safety goggles, and sturdy footwear.
  3. Clean After Every Use: It’s easy to forget, but try to make a habit of cleaning your hedge trimmer after each use. Even a quick wipe-down can prevent the buildup of sap and debris, keeping your blades sharp and efficient.
  4. Avoid Cutting Thick Branches: Hedge trimmers are designed for pruning hedges, not cutting down trees. Avoid using your trimmer on branches thicker than half an inch. Doing so can strain the motor and dull the blades, reducing the lifespan of your machine.
  5. Store with Care: Store it in a dry, cool place after cleaning and oiling your hedge trimmer. Hang it up instead of leaving it on the ground. This prevents oil from draining to one side and keeps the blades away from dust and dirt.
Store It in a Dry Cool Place

With these additional tips and tricks, you can keep your hedge trimmer in excellent condition, ensuring it’s always ready to tackle any unruly hedges in your yard.

5 Things You Should Avoid

  1. Avoid Neglecting Regular Maintenance: Regular maintenance is crucial for the longevity and performance of your hedge trimmer. Failing to oil and clean the blades after each use can lead to degradation and poor performance.
  2. Avoid Using Dull Blades: Working with dull blades can strain the motor and lead to uneven cuts. Make sure to sharpen your blades regularly and replace them if necessary.
  3. Avoid Ignoring Safety Measures: Never overlook safety when operating a hedge trimmer. Always wear the appropriate safety gear, like gloves and goggles, and be mindful of your surroundings to avoid accidents.
  4. Avoid Using the Wrong Oil: Always use the recommended lubricating oil for your hedge trimmer. Using the wrong type of oil can result in inadequate lubrication, causing the blades to wear out faster.
  5. Avoid Improper Storage: Storing your hedge trimmer in damp or humid areas can lead to rust and corrosion. Always store it in a cool, dry place and use a protective sheath to cover the blades.
Use the Recommended Lubricating Oil

By avoiding these mistakes, you can ensure your hedge trimmer stays in top shape and performs optimally for years.
