Petrol generator Güde GSE 4701 RS
Güde GSE 4701 RS is a 4-stroke petrol generator with an OHV engine of 224 cm³ and 5.5 kW, rated output 3,600 W, synchronous generator with automatic voltage regulator (AVR), recoil start, 15 L fuel tank and up to 13 hours of running time at 50% load. Manufactured by Güde GmbH & Co. KG, Wolpertshausen (Germany), founded in 1979. Distributed in Italy by Krollit, official Güde distributor since 2007.
Important: this generator must not be used to power electronically sensitive devices such as laptops, smartphones or audio equipment. The synchronous generator with AVR does not produce a clean sine wave equivalent to an inverter generator and is not suitable for modern switching-mode power supplies.

Who uses the GSE 4701 RS and for what
Krollit customers choose the GSE 4701 RS when the 3701 RS (2,800 W rated) is not sufficient. With 3,600 W rated and 14 A output, it powers more demanding loads in three main settings: construction sites running multiple tools simultaneously (200 L concrete mixer plus angle grinder plus lighting); farms requiring centrifugal pumps of 2–2.5 kW for large-scale irrigation; trade fairs and markets with combined resistive appliances (refrigerated displays, resistance heaters, fluorescent lighting). The 3,200 W continuous output offers significant headroom over the 2,500 W of the lower model.
Who the GSE 4701 RS is for
| Profile | Suitability | Reason |
|---|
| Construction or road site running multiple tools simultaneously | Suitable | 3,200 W continuous output supports a 200 L concrete mixer (approx. 1,800 W) plus an angle grinder at 1,200 W simultaneously, with 200 W headroom. |
| Farm with centrifugal irrigation pumps of 2–2.5 kW | Suitable | The 5.5 kW / 7.5 hp engine handles inrush currents of large-bore irrigation pumps that the 4.2 kW engine of the GSE 3701 RS cannot always sustain. |
| Event organiser with combined resistive loads above 2,500 W | Suitable | 3,600 W rated output allows combinations of resistive loads (heaters, lighting, commercial refrigeration) not manageable with the 2,800 W model. |
| User needing to power laptops, smartphones or digital audio equipment | Not suitable | The synchronous generator with AVR does not produce a clean enough sine wave for modern switching-mode power supplies: risk of damage to electronics. An inverter generator is required. |
| Use in enclosed spaces without adequate ventilation | Not suitable | Internal combustion engine: CO emissions are incompatible with enclosed spaces. Outdoor use or well-ventilated areas only. |
Not suitable for: electronically sensitive devices (laptops, smartphones, audio equipment, medical instruments, UPS systems); use in enclosed spaces; applications requiring frequency stability within ±0.5 Hz.

Professional applications
Construction site with multiple tools
With 3,600 W rated output and 14 A across 2 x 230 V sockets, the GSE 4701 RS simultaneously powers a 200 L concrete mixer (approx. 1,800 W) and a 1,200 W angle grinder, staying within the 3,200 W continuous output. The 200 W headroom allows sequential start of a third light tool (drill, small grinder) without overloading the generator.
Agricultural irrigation with large pumps
The 5.5 kW / 7.5 hp engine handles inrush currents up to 3–4 times the rated current of centrifugal irrigation pumps with 60–100 m³/h flow rates — inrush loads that the 4.2 kW engine of the GSE 3701 RS cannot always sustain. The 15 L tank provides 13 hours of running time at 50% load, covering a full evening irrigation shift.

Frequently asked questions
What is the practical difference between the GSE 4701 RS and the GSE 3701 RS, and when should the higher model be chosen?
The main difference is power output: 3,600 W rated and 3,200 W continuous versus 2,800 W / 2,500 W. The GSE 4701 RS allows simultaneous operation of a 200 L concrete mixer (approx. 1,800 W) and a 1,200 W angle grinder — a combination the 3701 RS cannot sustain continuously.
The GSE 3701 RS remains the better choice for sites with one heavy tool at a time or agricultural uses with pumps up to 1.5 kW. The GSE 4701 RS is the right option when total loads regularly exceed 2,500 W or when motor inrush currents require higher peak power. Runtime is slightly shorter (13 hours vs 16 hours at 50% load) and net weight is 47 kg vs 42.2 kg.
Can the GSE 4701 RS power a 200 L concrete mixer and an angle grinder at the same time?
Yes, as long as combined draws do not exceed the 3,200 W continuous output. A 200 L concrete mixer typically draws 1,600–1,800 W at operating speed; a 125 mm angle grinder draws 1,100–1,200 W. The combined total of 2,800–3,000 W falls within the 3,200 W limit, leaving a 200–400 W safety margin.
It is advisable to start the two appliances sequentially rather than simultaneously to avoid stacking inrush currents (which can be 3–5 times rated current for inductive motors at start-up). The built-in overload protection trips automatically if the instantaneous load exceeds the limit and resets once the load drops.
Why is the GSE 4701 RS not suitable for laptops and smartphones?
The synchronous generator with AVR produces 230 V AC at 50 Hz with automatic amplitude regulation, but the waveform can exhibit harmonic distortion and frequency variation beyond the tolerance of modern switching-mode power supplies in laptops, smartphones and digital audio equipment.
Inverter generators convert AC to DC and back, producing a clean sine wave with THD below 3%, suitable for all electronic devices. The GSE 4701 RS is not an inverter generator. For powering sensitive devices, Güde offers a range of inverter generators available through the Krollit catalogue.
What is the maintenance schedule for the GSE 4701 RS 4-stroke OHV 224 cm³ engine?
Routine maintenance includes: engine oil change (0.6 L, grade 15W40 or 10W30) every 50 operating hours or at least once a year; air filter cleaning or replacement every 25 hours; spark plug check and adjustment every 100 hours; spark plug replacement every 200 hours.
Before each use, check the oil level: the low-oil shutdown automatically cuts the engine if the level drops below the minimum. Unused fuel must be removed from the tank if the generator will be stored for more than 30 days to prevent carburettor deposits. Original Güde spares are available from Krollit warehouse in Monteforte Irpino (AV).
How does the noise level of the GSE 4701 RS compare to the GSE 3701 RS?
The GSE 4701 RS declares a sound power level of LWA 97 dB, one decibel more than the LWA 96 dB of the GSE 3701 RS. A difference of 1 dB is not perceptible to the human ear under normal conditions: both models produce approximately 70–75 dB(A) of sound pressure at 7 metres.
Use of petrol generators is subject to local noise ordinances in most European countries. On licensed construction sites specific exemptions typically apply. The generator is certified Euro 5 for exhaust emissions. Always check local regulations before operating in residential or semi-residential areas.
Can the GSE 4701 RS be used as a backup power source during a mains outage?
