This document provides the original instructions for the YARD FORCE GM B40 / XSS40D petrol lawnmower, a machine designed specifically for cutting grass in domestic settings. It emphasizes the importance of reading and understanding the manual thoroughly before assembly, operation, or maintenance to ensure safe and effective use. The manual highlights that operating the product without familiarity with these instructions is dangerous and could lead to serious injury, death, or damage to the machine. It also states that the equipment is not designed for commercial, trade, or industrial applications, and its warranty will be voided if used for such purposes.
The YARD FORCE GM B40 / XSS40D is a petrol-powered lawnmower designed for cutting grass. It features a single-cylinder 4-stroke engine and is equipped with a grass collection bag to gather cuttings during operation. The machine allows for adjustment of the cutting height to suit different grass lengths and conditions. Starting the engine involves a primer bulb for cold starts and a pull cord handle. The lawnmower is designed for walking behind, with an upper handle and a STOP/START lever for control.
Before operation, users must ensure the engine is filled with the correct grade of oil and unleaded petrol. The manual provides detailed instructions for checking oil levels and refuelling, emphasizing safety precautions such as refuelling in a well-ventilated area, avoiding smoking or open flames, and preventing overfilling. The cutting height can be adjusted by pulling a lever towards the wheel and moving it to one of five positions. It is advised not to use the lowest cutting height for the first cut of the season or in drought conditions, cutting only about one-third of the grass height at a time.
To start the engine, for a cold engine, the primer bulb should be pressed 3-5 times. For a warm engine, the primer is generally not needed unless the engine stopped due to lack of petrol. The start/stop bar must be pulled towards the user and held in place, then the starter handle and rope are pulled briskly until the engine starts. To stop the engine, the start/stop bar is simply released. The manual also provides troubleshooting steps for a flooded engine, including removing and drying the spark plug.
When mowing with the collection bag, users are instructed to maintain a firm grip on the upper handle and stop/start bar, walking along with the mower rather than running. Caution is advised when mowing uneven or rough ground, maintaining stable footing, and mowing across slopes (never up and down). The maximum recommended slope is 15°. For optimal results, grass should be dry, as wet grass can clog the blade and collection system. If the lawnmower is not collecting cuttings efficiently, it could be due to a blocked discharge chute, a full grass bag, or a clogged underside of the mower deck.
The manual outlines a comprehensive maintenance schedule, including tasks to be performed after every use, after 12 hours of use, after 24 hours of use, and after 36 hours of use. Key maintenance activities include cleaning, checking/replacing the air filter, checking/replacing the spark plug, checking/changing engine oil, and checking/replacing the cutting blade.
Cleaning: After each use, it is crucial to keep the machine clean and well-lubricated, ensuring the chute and the underside of the deck are clear of wet debris. Grass cuttings and other debris should not be allowed to dry and harden on mower surfaces, as this affects cutting and collection performance. The lawnmower should never be cleaned with a water jet or high-pressure cleaner, and aggressive cleaning agents or solvents should be avoided.
Air Filter: The air filter element must always be installed when running the engine. To clean or replace it, the cover fastener is loosened, the cover opened, and the filter removed. Debris can be loosened by gently tapping the filter on a hard surface. If excessively dirty, the filter should be replaced.
Spark Plug: After the engine has cooled, the spark plug boot is removed with a twist, and the spark plug is removed using the supplied socket spanner. The plug should be cleaned with a wire brush, and the gap set to 0.51mm using a feeler gauge. When reinstalling, the spark plug should be tightened carefully by hand to avoid cross-threading, then further tightened with the spanner to compress the washer.
Engine Oil: The engine oil should be changed at the end of every season or after the first 5 hours of use to prolong engine life. To change the oil, the lawnmower is tilted towards the oil filler, the dipstick removed, and the used oil drained into a container. The engine is then refilled with fresh SAE 30 oil (or equivalent, e.g., SAE 5W/30, SAE 10W/30), ensuring the oil level is between the min and max marks on the dipstick.
Cutting Blade: The metal blade should be renewed after 50 hours of mowing or after 2 years, whichever comes first. Regular checks are necessary, and a blunt blade should be sharpened or replaced to prevent poor cutting, excessive vibration, and uneconomical engine running. When replacing the blade, garden gloves and a spanner wrench are required. The blade bolt is unscrewed anti-clockwise, and the blade, washer, and blade adaptor are inspected for damage. A new blade is fitted, ensuring it is correctly located on the studs of the blade flange, and the washer and bolts are replaced and firmly tightened. The up-turn of the blade must project into the motor compartment.
Storage: For short-term storage, the engine should be allowed to cool, the grass bag emptied, and all debris cleaned from under the mower deck. The lawnmower should be stored on a flat, level surface in a dry, safe place inaccessible to children. For extended storage (longer than 6 weeks or at the end of the season), storage maintenance is required to prevent fuel contamination and starting problems. This involves emptying the petrol tank (outdoors, away from flames), running the engine until all remaining petrol is used up, changing the engine oil, and filling the cylinder with approximately 20ml of oil before slowly pulling the starter handle to bathe the cylinder wall. The spark plug is then reinstalled, and the cooling fins and housing are cleaned. The machine should be stored in a well-ventilated place. The manual explicitly warns against tipping the mower upside down or storing it with petrol in the tank inside a building where fumes could reach an open flame or spark.
