Q: What should I do if the MAX mark is faded or missing on the oil gauge?

If the MAX mark is no longer visible on the oil gauge of your Combi 548 SE, you cannot properly check the level, which poses a risk to the engine. According to your mower's documentation, the oil level must remain between the two marks MIN and MAX . Without the MAX marking, you risk overfilling with oil, which can cause: Smoke from the exhaust Fouling of the spark plug or air filter Premature engine wear Recommended solution: Replace the gauge. The filler cap includes the gauge, so it is a single part. Contact an authorized STIGA service center or your dealer to obtain the original cap/gauge. You can also check directly by measuring: start with a small amount of oil, then visually check with the new gauge to establish the correct level.

Question 1

What are the dimensions of the STIGA Collector 48 S package?

Accepted Answer

The manual for the STIGA Collector 48 S states that the dimensions of the mower itself are approximately 150 x 55 x 100 cm (L x W x H).

However, the manual does not specify the exact dimensions of the original packaging. Generally, for a mower of this size, the shipping package is slightly larger than the machine itself to ensure optimal protection during transport and delivery.

Question 2

Why won't my STIGA Combi 748 SE lawn mower start with the electric start system?

Accepted Answer

If your STIGA Combi 748 SE lawn mower equipped with electric start does not start, here are the checks to perform in order:

1. Check the battery condition and charge

Press the battery button to check its status via the LED indicators. If the lights are red, this indicates a weak or discharged battery. You must fully charge the battery before any starting attempt. An insufficiently charged battery is the most common cause of failure to start with electric start.

2. Check the correct insertion of the battery

Ensure that the battery is properly seated in its compartment until you hear a click. A poorly secured battery will not establish the necessary electrical contact for starting.

3. Check the prerequisites for starting

All controls are disabled (no unintended movement of the machine)
The fuel tank contains unleaded gasoline (minimum 90 octane, max 10% ethanol)
The engine oil level is correct (check between the MIN and MAX marks)
The air filter is clean and properly installed
The spark plug cap is firmly connected and free of dirt

4. Check the spark plug electrode

If the previous checks are good, clean the spark plug electrode and check the gap (should be between 0.6 and 0.8 mm). A carbon deposit or incorrect gap prevents ignition.

Important: Never use the engine in an enclosed space due to the risk of carbon monoxide poisoning.

Question 3

Why does my STIGA Multiclip Pro 950 SX AE mower make excessive noise even though the blade is securely attached?

Accepted Answer

Possible causes of excessive noise

Even if the cutting blade is securely attached, abnormal noise can come from several sources:

Grass and debris accumulation - Residual chopped grass or debris accumulated under the deck can vibrate and generate noise. Regularly clean the mower after each use.
Blade condition - A worn, unbalanced, or damaged blade produces noise even if it is tight. The manual recommends professional servicing of the blade when necessary.
Wet grass - The mower makes more noise in wet grass. The manual specifies that you should mow when the lawn is dry for optimal efficiency and less vibration.
Transmission system - Annual maintenance of the transmission system is recommended to avoid abnormal operating noises.
Clogged air filter - Inspect the air filter monthly according to the maintenance schedule.

Solutions: Start by checking the lower deck and cleaning out any debris. Wait for the grass to dry before mowing. If the noise persists, contact an authorized STIGA repairer for a diagnosis of the transmission system and blade servicing.

Step 4: You can then remove the blade.

This operation is necessary for cleaning the blade or replacing it. Make sure the engine is completely stopped and cooled down before handling the blade to avoid injuries.

Question 5

What should I do if the MAX mark is faded or missing on the oil gauge?

Accepted Answer

If the MAX mark is no longer visible on the oil gauge of your Combi 548 SE, you cannot properly check the level, which poses a risk to the engine.

According to your mower's documentation, the oil level must remain between the two marks MIN and MAX. Without the MAX marking, you risk overfilling with oil, which can cause:

Smoke from the exhaust
Fouling of the spark plug or air filter
Premature engine wear

Recommended solution: Replace the gauge. The filler cap includes the gauge, so it is a single part. Contact an authorized STIGA service center or your dealer to obtain the original cap/gauge. You can also check directly by measuring: start with a small amount of oil, then visually check with the new gauge to establish the correct level.

Question 6

Why does the mower have no power?

Accepted Answer

If your STIGA Combi 748 Q AE mower has no power or won't start, here are the checks to make:

Checks for the lithium-ion battery

Completely discharged battery: Place the battery on the charger and let it recharge. An automatic protection device cuts off power in case of total discharge - it can be recharged at any time, even partially.
Correct insertion: Remove and firmly reinsert the battery until it clicks. A poorly seated battery cuts off power.
Battery contacts: Clean the metal contacts with a dry cloth. Oxidation or dust prevents conductivity.
Safety key: Check that the safety key is properly inserted - it is mandatory for starting the 748 Q AE model.

Checks for the charger

Ensure the charger is properly plugged into a functional outlet (test with another device).
Check the condition of the charger power cable.
If the charger does not respond, it may be defective and require replacement with an original STIGA part.

Technical note: The lithium-ion battery life is up to 40 minutes. It varies depending on the cutting height and grass density. The optimal charging range is from 0 to 45°C.

Question 7

Can a missing piece of plastic in front of the sensor of the STIGA G 600 robotic mower cause malfunctions?

Accepted Answer

Yes, a missing piece of plastic in front of the sensor of the STIGA G 600 robotic mower can cause significant malfunctions. The STIGA G 600 is equipped with several essential safety sensors, including a lift sensor that detects if the robot is lifted off the ground. This piece of plastic serves as protection for the sensor by keeping it free from obstruction by dust, grass, and debris.

Function of the lift sensor: This sensor automatically stops the robot as soon as it is lifted off the ground for safety reasons. The missing piece of plastic leaves the sensor exposed to debris that can obstruct it.
Consequences of lack of protection: Without this protective piece, debris, grass, and dust accumulate in front of the sensor. This prevents correct detection of the robot's lift, which can cause a malfunction or unexpected stopping of the robot.
Additional issues: Obstruction of the sensor can also generate error messages in the STIGA.GO app, unexpected stops, or loss of recognition of the robot's position.

To ensure optimal operation of your STIGA G 600, it is recommended to replace this missing protective piece. If you cannot find the spare part from a dealer, contact the official STIGA customer service. In the meantime, regularly clean the area around the sensor to remove grass and dust deposits that could obstruct the sensor, as described in the maintenance section of the manual (paragraph 6.2).

Question 8

Does the STIGA G 600 model have a magnetic sensor on the cover?

Accepted Answer

Yes, the STIGA G 600 model is equipped with a magnetic sensor located on the protective cover. This safety device detects whether the cover is properly closed and in place before starting the mower.

Operation of the system:

A magnet located on the cover interacts with the magnetic sensor to confirm the correct closure of the shell (B).
When the cover is properly positioned and closed, the sensor detects the presence of the magnet and allows the robotic mower to start.
If the cover is improperly closed, removed, or partially open, the sensor does not detect the magnet, which automatically prevents the mower from starting.

Safety measures: For safety reasons, the robotic mower can only start when the cover is completely closed. This protection prevents any risk of contact with moving parts or blades during operation.

Sensor maintenance: Regularly check that the magnetic sensor and the magnet are not clogged with dirt, debris, or dried grass. A simple cleaning with a dry cloth is usually sufficient. Any obstruction of the sensor would prevent the detection of the magnet and block the mower from starting. If the problem persists after cleaning, do not hesitate to contact a STIGA service center.

Question 9

What sensors are present on the STIGA G 600 mower and what are they for?

Accepted Answer

The STIGA G 600 robotic mower is equipped with several essential sensors that ensure its autonomous operation, precise navigation, and user safety. Here are the main sensors present on this guide wire model:

Front coil sensors: These two sensors detect the signal from the perimeter wire installed around your lawn. They allow the robot to stay within the defined mowing area and ensure complete coverage of the surface through a random navigation statistical algorithm.
Lift sensor: This sensor detects if the mower is lifted. In the event of lifting, the sensor immediately stops operation to prevent accidents and injuries.
Anti-tilt sensors (inclinometers): They detect the tilt of the robot. If the tilt exceeds 45% on a slope or if the robot tips over, these sensors automatically stop operation for safety.
Rain sensor: This sensor detects rain and allows sensitivity to be set at three levels. When it rains, the robot automatically returns to its charging station to protect the electrical components.
Magnetic hood sensor: Located on the upper hood, this sensor detects the correct closure of the mower. If the hood is not properly closed or misaligned, the sensor does not emit the signal, preventing the robot from starting for safety reasons.
Obstacle detector: It identifies obstacles in the robot's path and allows navigation that avoids collisions.
Battery sensor: This sensor monitors the charge status of the E-Power 2.5 Ah battery and indicates when a recharge is necessary via the indicator lights on the control panel.

All of these sensors work in synergy to allow the STIGA G 600 to operate autonomously and safely. Thanks to the perimeter wire and coil sensors, the robot mows randomly while remaining confined to the defined area. In case of suspected malfunction, check that these sensors are not obstructed by dirt or grass (see the maintenance section of the manual).
