Frequently Asked Questions - GHS 520 7 TE Güde

What is the splitting force of the Güde GHS 520/7 TE?
The GHS 520/7 TE develops a splitting force of 7 tons, with a maximum hydraulic pressure of 242 bar. This power allows it to handle logs with hard or slightly knotted fibers without special effort from the operator.
What log length can be split with this device?
The log splitter accommodates logs with a length between 200 and 520 mm. It is advisable to cut the logs to the correct length before placing them on the log guide for optimal operation.
What is the maximum diameter of logs to be processed?
The maximum accepted diameter is 250 mm. For larger diameter logs, they need to be pre-split into quarters before positioning them under the splitting wedge.
Does the GHS 520/7 TE plug into a standard power outlet?
Yes, it operates on the standard single-phase network 230 V - 50 Hz. Its power consumption of 2,300 W requires a circuit protected by an appropriate circuit breaker. In case of an extension cord, opt for a minimum section of 2.5 mm² to avoid voltage drops.
Can the log splitter be used continuously all day?
No. The motor operates in mode S6/40%, which corresponds to about 4 minutes of splitting followed by 6 minutes of pause in a 10-minute cycle. Adhering to this cycle is essential to avoid overheating and prolong the motor's lifespan.
What hydraulic oil should be used and in what quantity?
The hydraulic reservoir requires 3.5 liters of HLP 46 oil. Check the level before each work session and do not use a viscosity different from the recommended one, as it may damage the hydraulic system.
How does the two-hand safety control work?
The device is equipped with a two-hand control requiring the operator to keep both hands on the control elements during splitting. This active safety prevents any accidental contact with the work area. A protective cover in the splitting area reinforces this device.
What is the noise level emitted during use?
The guaranteed acoustic power level (LWA) is 89 dB(A). Wearing approved ear protection is recommended during prolonged use, in accordance with individual protection regulations.
Is the log splitter easy to move from one place to another?
Yes. The device is delivered with an integrated base frame and transport wheels. Ergonomic handles facilitate handling despite a gross weight of approximately 69 kg.
What regular maintenance is necessary?
Before each use, check the hydraulic oil level and the condition of the hose. After each session, clean wood chips from the wedge and support table. Replace the HLP 46 oil according to the intervals indicated in the user manual.
What to do if the log splitter cannot split a log?
Remove the log without forcing, then reposition it on a natural crack or reduce its diameter with an axe before trying again. Also check the hydraulic oil level: an insufficient level significantly reduces the available splitting force.
Is the device protected against water and chip projections?
Yes, the motor has a protection rating of IP 54, which protects it against water splashes in all directions and dust. This allows outdoor use in normal weather conditions, but avoid any direct rain exposure.

Why does the wedge of the Güde GHS 520 7 TE splitter rise immediately after being lowered to the bottom position?
Frequently Asked Questions - 01/04/2026
Response Notice-Facile

If the wedge of your Güde GHS 520 7 TE splitter rises immediately after being lowered to the bottom position, it indicates a hydraulic problem preventing the system from maintaining pressure. Here are the main causes and their solutions, to be checked in this order.

Insufficient hydraulic oil level - This is the most common cause. Your splitter contains 3.5 liters of HLP 46 hydraulic oil. Check the level on the reservoir gauge. If the level is too low, top up the oil to the mark. Insufficient oil creates a pressure loss that prevents the wedge from staying locked in the bottom position.

Defective or clogged hydraulic valve - The control valve maintains system pressure. If the hydraulic piston on the valve does not adhere completely, pressure escapes and the wedge rises. Clean the valve by ensuring that the piston moves freely. Also check that all screws on the lowering rod are tight, as a bent or misaligned rod prevents the piston from adhering. If the valve is too damaged, only a qualified repair shop can replace it.

Checking hydraulic circuits - Check the tightness of all hydraulic hoses and connections around the main cylinder. Even a small leak reduces pressure insufficiently. Also inspect the bottom of the reservoir: if debris accumulates there, it can clog the pipes and reduce flow, preventing the system from maintaining the load. Clogging can be resolved by cleaning the hoses.

Mechanical cleaning and lubrication - Wood sap sometimes creates a sticky layer that interferes with the locking mechanism. Clean the splitting column (80 x 120 mm) and the wedge guides with a damp cloth. Then apply a lubricant to the lowering rod and sliding elements to ensure smooth operation.

Two-lever control system - Check that the two-lever control operates correctly. Incorrect handling or a misaligned lever can prevent load maintenance. Ensure that the levers return to the neutral position after each use.

If after these checks the wedge continues to rise immediately, contact an authorized Güde repair shop at +49 (0) 79 04 / 700-360 or support@ts.guede.com, as this indicates an internal failure of the hydraulic system requiring professional expertise.
