What You'll Learn
Choosing the right oil
When selecting an oil, opt for a machine lubricating oil that is specifically designed for power tools or cutting equipment. Look for a penetrating oil that can withstand heat and penetrate the main components of your hedge trimmer effectively. A popular option is Ballistol Multi-Purpose Oil, an aerosol spray commonly used for firearms. It is designed to withstand high temperatures and provides excellent penetration.
If you prefer a more environmentally friendly option, you can consider biodegradable oils. These oils will not harm the plants you are trimming or the surrounding soil and will not attract animals. Vegetable oil spray, for example, can be adjusted based on the outdoor temperature and is a good option for eco-conscious individuals.
Additionally, some users recommend Chain & Cable Lube, which can be found in environmentally friendly types. This type of lubricant may need to be reapplied regularly as it washes off easily. However, it effectively reduces friction, improves engine efficiency, and creates clean cuts.
Remember to always follow the manufacturer's instructions for oil type and frequency of lubrication. Regularly oiling your hedge trimmer before or after each use will help maintain its performance and prolong its lifespan.

How often to oil
How often you should oil your electric hedge trimmer depends on several factors, including the challenges your trimmer faces, how often you use it, and how long you don't use it for.
Some sources recommend oiling your trimmer before or after each use. This helps to keep friction between the blades low, preventing excess heat that can bend the blades. It also prevents rust by keeping water out of the blades.
If your trimmer is new, it won't need lubrication for a while. You can oil it at the beginning and end of every season to minimise friction and heat between the blades and to provide a protective coating to prevent rust.
If you're using your trimmer for an extended period, oil it at the beginning of the day. This will help prevent sap, leaves, and debris from sticking to the blades.
Some electric hedge trimmers are oiled for life, meaning you don't need to check, change, or top up the oil. However, if your trimmer doesn't fall into this category, you should check and top up the oil every 25 hours of use or every three seasons.

Preparing the trimmer
Inspect the Trimmer
Before each use, it is important to inspect your electric hedge trimmer to ensure it is in good working condition. This includes checking the blades, electrical cord, air filter, spark plugs, and the general appearance of the tool. If you notice any damage or excessive wear, it is recommended to consult a qualified service engineer for repairs.
Clean the Blades
Keeping the blades clean is essential to prevent rust and corrosion. Use a stiff brush or wire brush to remove any organic material, sap, leaves, or debris from the blades. You can also use a clean cloth or rag to wipe down the blades. Ensure the blades are completely dry before proceeding to the next step. It is recommended to clean the blades after each use to maintain their sharpness and prevent damage.
Choose the Right Lubricant
Selecting an appropriate lubricant is crucial for effective trimmer maintenance. You can use a lightweight machine oil, such as 3-in-1 oil or SAE20 engine oil, specifically designed for power tools. Vegetable oil is a more environmentally friendly option. Avoid using home oils, as they are not suitable for this purpose. If your trimmer is battery-powered, ensure the battery pack is removed before applying any lubricant.
Apply the Lubricant
When applying the lubricant, be as gentle as possible to avoid creating nicks or scratches on the blades. Use a machine oil applicator, paintbrush, or oil-covered rag to apply the oil along the edge of the top blade. You can also use WD40, but it may not stay on the blades as long as traditional oils. It is recommended to oil the blades before or after each use, or at least once or twice a month, depending on the frequency of use and storage conditions.
Store the Trimmer Properly
When not in use, store your electric hedge trimmer in a dry and cool place, away from direct sunlight or moisture. Keep the blades in a scabbard, as they can still move if pushed and pose a safety hazard. If you have a gas-powered trimmer, ensure it is drained of gas or use a gas stabilizer to keep the gas fresh during extended periods of storage.

Applying the oil
When it comes to the oiling process, you can use a machine oil applicator, a paintbrush, or a rag soaked in oil. Apply the oil generously to the blades, ensuring that you cover all the vital points. This will help prevent rust and corrosion, and keep the blades moving smoothly. It is recommended to oil your trimmer before or after each use, or at the beginning and end of the season.
If you are using a grease-based lubricant, such as white lithium grease, remove the transmission bung and fill the transmission grease, leaving some space for the grease to move around when the blades are in motion. You can also use wax or silicon spray as lubricants, although they may need to be reapplied more frequently.
In addition to oiling, it is important to clean your hedge trimmer blades regularly. Use a stiff brush and a cloth to remove any foliage and organic material, which can cause corrosion if left on the blades. Allow them to dry completely before applying oil or lubricant.
By following these steps and maintaining your electric hedge trimmer, you can ensure its effectiveness and longevity.

Aftercare and maintenance
To keep your electric hedge trimmer in good condition, regular maintenance is required. This includes cleaning and lubricating the blades. Before cleaning or performing any maintenance, ensure the power source is turned off and unplugged. If your trimmer is battery-powered, remove the battery pack.
Cleaning the blades is important to prevent damage and keep them sharper for longer. Use a stiff brush to clean any organic matter from the blades, then wipe them down with a cloth. Allow them to dry completely before applying any lubricant.
Lubricating the blades of your electric hedge trimmer is crucial to prevent friction and heat, which can cause the blades to bend. It also helps prevent rust and corrosion, and stops sap, leaves, and debris from sticking to the blades. Oil is the most common lubricant, and you can use any machine oil as long as it is a penetrating oil. Vegetable oil is an environmentally friendly option, while motor oil and bar and chain oil are designed for power tools. Apply the oil generously to the blades and wipe off any excess.
In addition to oil, you can use grease to lubricate the gears and bearings of your hedge trimmer, especially if it is gas-powered. White lithium grease is commonly used, and you can use a grease gun to pack the transmission. You can also lubricate the gear case with a special grease after every 50 hours of operation.
Other types of lubricants include wax, which provides excellent protection against rust and corrosion but may need to be reapplied frequently. Silicon spray is ideal for electric hedge trimmers as it is non-greasy and protects against rust and corrosion. Dry lubricants such as graphite powder or Teflon spray are perfect for dusty environments as they do not attract dust and dirt.
Remember to always consult your hedge trimmer's instruction manual for specific recommendations and maintenance procedures. Regular cleaning and lubrication will help extend the life of your electric hedge trimmer and keep it working optimally.
