Frequently Asked Questions - GHS 520 GUDE
How to start the GHS 520 hedge trimmer?
Make sure the tank contains the petrol-oil mixture (1:50 for a 2-stroke engine). Activate the safety lock, then pull the starter with a quick motion. Once started, let it warm up for a few seconds before cutting.
What fuel to use for the GHS 520?
Use a mixture of unleaded petrol (grade 95) and 2-stroke oil in a ratio of 1:50. Do not exceed this dose to avoid deposits and smoke.
How to sharpen the hedge trimmer blades?
Remove the blades (according to the manual), clamp them in a vice and use a flat file to work on the teeth following the original angle. Avoid electric grinders which overheat the steel and reduce its lifespan.
What to do if the machine does not start?
First check the spark plug: if dirty or wet, clean or replace it. Check the air filter and the tank. Prime the fuel by pressing the primer bulb several times.
What safety precautions should be taken?
Wear protective gloves, goggles and hearing protection. Hold the machine with both hands, keep bystanders away, and never cut above shoulder height.
How to clean the GHS 520 after use?
Remove plant debris with a brush. Clean the blades with a cloth soaked in oil and clean the machine body. Check that the air intakes are not blocked.
What is the weight of the GHS 520?
The GHS 520 weighs about 4.8 kg, making it a manageable device for cutting medium to tall hedges. The anti-vibration system reduces fatigue.
Can thick branches be cut with this hedge trimmer?
This hedge trimmer is designed to cut branches up to 24 mm in diameter. Beyond that, use a branch cutter to avoid jamming the blades and damaging the engine.
Does the engine need a break-in period?
Yes, during the first 2 hours, avoid working at full load and vary the speeds. Check the tightening of the screws and the fixing of the blades after the break-in period.
Where to find spare parts for the GHS 520?
Contact GUDE customer service or your dealer. Common parts such as blades, spark plugs, air filters and carburettors are available online or in specialist stores.
