Function Description:
The YARD FORCE Y4GM A41 P000 is a petrol-powered lawn mower designed for cutting lawn areas in private homes and gardens. It is intended for domestic use and is not warranted for commercial, trade, or industrial applications. The mower features a single-cylinder 4-stroke engine and is equipped with a grass catcher for collecting clippings. It has adjustable cutting height settings to suit different lawn conditions.

Usage Features:
The lawn mower is designed for ease of use with several user-friendly features:
- Handle Assembly: The handle is assembled using round head bolts and fixing knobs, with a rope guide on the right handle for convenience. The upper handle can be unfolded and fixed into place.
- Cable Management: A cable clip is provided to tidy the throttle control cord to the handle.
- Grass Catcher: The grass catcher consists of a fabric bag with a metal frame, which attaches to the rear of the mower. A rear flap secures the grass catcher in position.
- Engine Start/Stop: The engine is started by pressing the primer bulb 3-5 times, moving the throttle lever to the rabbit position, and then pulling the starter handle with a sharp pull. To stop the engine, the throttle lever is moved to the stop position.
- Adjustable Cutting Height: The cutting height is centrally adjusted using a handle, offering seven positions from 20mm to 75mm. This adjustment should only be made when the engine is switched off and the spark plug lead is removed.
- Mowing Guidance: The manual advises walking, not running, and mowing across slopes rather than up and down. It recommends avoiding wet grass and excessively steep slopes. For best results, only about one-third of the grass height should be cut.
- Flooded Engine Procedure: Instructions are provided for clearing a flooded engine, which involves moving the throttle lever to stop, removing and drying the spark plug, and then reinstalling it before attempting to restart.
Maintenance Features:
Regular maintenance is crucial for the longevity and performance of the lawn mower. The manual outlines a comprehensive maintenance schedule and procedures:
- Engine Oil:
- Initial oil change recommended after the first 8 hours of use.
- Regular checks of the engine oil level are required before each use.
- The oil filler cap/dipstick is used to check the level, which should be at the top of the full indicator.
- For new engines, 0.4L of 4-Stroke oil (Bynorm 4 stroke lawn mower oil recommended) should be added.
- Oil changes involve tilting the mower, draining old oil, and refilling with SAE30 oil to the correct level.
- Spark Plug:
- The spark plug should be checked at 12 hours of use, cleaned at 24 hours, and replaced at 36 hours.
- Maintenance involves disconnecting the spark plug lead, removing the plug with a spanner, cleaning it with a wire brush, and setting the gap to 0.7-0.8mm using a feeler gauge.
- Air Filter:
- The air filter should be cleaned at 12 hours of use, checked at 24 hours, and replaced at 36 hours.
- Maintenance includes unclipping and removing the cover, tapping the element to remove dirt, or replacing it if excessively dirty. The manual warns against running the engine without the air filter and cleaning it with petrol or inflammable solvents.
- Blade Bar:
- The blade bar should be inspected annually and sharpened/balanced by an authorized service center.
- Replacement is recommended after 50 hours of mowing or 2 years, whichever comes first.
- Blade replacement requires garden gloves and a spanner wrench. The blade bolt is unscrewed counterclockwise, and the new blade is fitted, ensuring correct location, and then tightened to 45-50N·m.
- Grass Catcher: The grass catcher should be checked frequently for wear or deterioration and replaced if damaged. It should be emptied when clippings start to trail behind the mower.
- General Cleaning: All debris from under the mower deck, cooling fins of the cylinder, and housing should be cleaned regularly.
- Storage:
- Short Periods (less than 15 days): Allow the engine to cool, ensure the grass catcher is empty, clean debris from the deck, and store on a flat, level surface in a safe place.
- Extended Periods (more than 15 days): Empty the petrol tank (outdoors, away from ignition sources), clean up spilled fuel, run the engine until all fuel is used, empty warm oil and refill with fresh oil, clean cooling fins and housing, clean the entire mower, and store in a well-ventilated place.
- Transport: Before transport, empty the petrol tank, run the engine until all fuel is used, empty engine oil, disconnect the spark plug lead, and use original packaging if possible.
The manual includes numerous warning symbols and safety instructions to prevent injury and damage:
- Read the operator's manual before use.
- Keep bystanders, children, and pets away from the mower.
- Wear safety footwear, long trousers, safety glasses, and hearing protection.
- Inspect the area for objects that can be thrown by the blades.
- Petrol is highly flammable; refuel outdoors, do not smoke, and do not refuel a hot or running engine.
- Do not operate the engine in confined or poorly ventilated areas due to toxic exhaust gases.
- Keep hands and feet clear of cutting blades and discharge opening.
- Remove the spark plug lead before maintenance.
- Do not open or remove safety shields while the engine is running.
- Check engine oil and fuel levels before every use.
- Do not change engine governor settings or overspeed the engine.
- Disengage all blade and drive clutches before starting.
- Stop the engine and disconnect the spark plug wire before clearing blockages, checking, cleaning, or working on the mower, or if abnormal vibrations occur.
- Reduce throttle setting during engine shut down.
- Store fuel in specifically designed containers.
- Allow the engine to cool before storing.
- Keep the engine, silencer, and fuel storage area free of grass, leaves, or grease to reduce fire hazard.
