Regular hedge trimmer maintenance keeps blades sharp and prolongs your machine’s lifespan – keeping every cut safe and precise. With over a century of experience, we offer expert servicing for all major brands, helping you to get the most from your tools.

Read on for pro-level tips that’ll keep your hedge trimmer running smoothly, season after season.

Tools & Equipment You’ll Need

Before you start, gather a few essentials:

A clean cloth
Stiff brush
Suitable lubricant
Screwdriver
Protective gloves or goggles
Charger/spark plug spanner (for cordless or petrol models)

If your toolkit is in need, we stock a full range of oils, lubricants, and PPE to help you carry out maintenance safely and effectively.

Step-by-Step Hedge Trimmer Maintenance Routine

Keeping your hedge trimmer in top working order doesn’t take long – and regular checks can prevent costly repairs or downtime later. Follow these simple routines to keep your trimmer sharp, safe, and reliable all year round.

Before Every Use

Always give your trimmer a quick inspection before starting work.
Look for loose screws or damage to the housing, blades, or handle grips.
Check blade tightness – loose blades can cause damage or injury.
Remove dirt or residue that could affect blade performance.
Make sure the trigger and safety lock are functioning properly.

After Every Use

A clean tool lasts longer and works better.
Wipe off any sap, leaves or moisture with a dry cloth.
Use a soft brush to dislodge compacted debris around the blade guard or motor vents.
Store indoors, ideally in a dry, secure place. Avoid leaving your machine out in the damp, which can lead to corrosion.

Weekly or Monthly Hedge Trimmer Checks

Depending on how often you use your trimmer, the following checks should be done regularly:

Lubricate the blades to reduce friction and prevent wear.
Inspect the power cable (corded models) or battery condition (cordless models) for any signs of damage.
Look for signs of rust or corrosion, especially around joints or moving parts. A quick wipe-down with a rust inhibitor spray can help.

Seasonal or Annual Servicing of Hedge Trimmers

At least once a year – ideally before peak hedge-cutting season – book in a full service or carry out more thorough checks:

Sharpen the blades or have them professionally serviced to keep cutting performance high.
Petrol models: Clean or replace the air filter, inspect the spark plug, and check the ignition system.
Corded and cordless models: Run an electrical safety test to ensure everything’s in safe working order.

For complete peace of mind, we provide expert servicing and repairs for all hedge trimmer types. We also provide a collection and delivery service if you’re unable to bring your machine in.

Sharpening Your Hedge Trimmer Blades

Blunt blades tear rather than cut, leading to untidy results and plant damage. If you have the right file and a steady hand, light sharpening can be done at home – but it’s easy to overdo it and affect blade alignment.

For a professional finish, we recommend leaving it to the experts. We can conduct hedge trimmer blade sharpening in-store (price on application), helping restore performance without the risk of damaging your machine.

Storage Tips to Extend Your Hedge Trimmer’s Lifespan

Storing your hedge trimmer properly is just as important as cleaning it.
Always keep it in a dry, frost-free shed or garage, preferably locked to avoid accidents or theft.
Use a blade cover to protect both the cutting edge and anything nearby.
Avoid leaving your machine outside, even under a tarp.
If your model came with a case, use it – if not, we stock a range of protective covers and accessories to help keep your equipment in top condition between uses.

Common Hedge Trimmer Issues & When to Call the Experts

If your hedge trimmer starts losing cutting power, makes unusual grinding noises, or begins overheating, it’s time to stop and investigate. These symptoms can indicate dull blades, gearbox issues, or electrical faults.

For petrol models, poor starting or misfiring could point to spark plug or fuel system problems. Rather than risk further damage, let the professionals take a look.

We can oversee full diagnostic and repair services for all major brands – including collection and delivery if you can’t bring the machine in yourself. It’s the quickest way to get your equipment safely back to full working order.
