Usage Features:
The lawn mower is equipped with a soft grip, upper and lower handles, a brake lever/stop lever, fixing knobs, a grass bag, a fuel tank cap, a primer, front decorative cover, and a height adjusting handle. It also features rear and front wheels, an engine oil cap, side discharge cover, side discharge chute, deck, spark plug boot, pull start, and a rear discharge cover.
Assembly and Setup:
- Handle Assembly: The lower handle is fastened to the device using two bolts and two small knobs on each side. The upper handle is then unfolded and fixed to the lower handle using big knobs and bolts. The rope guide must be on the right handle when standing behind the mower.
- Connection Cord: The connection cord is fixed to the handle with the supplied cord clip.
- Grass Bag Assembly: Plastic clips are secured over the metal frame of the grass bag.
- Grass Bag Onto Mower: The rear discharge cover is lifted, and the grass bag is hooked in. Releasing the cover secures the bag.
- Mulching Plug Assembly: The grass bag is removed, and the plastic mulching plug is pushed into the discharge chute until locked. The flap is then released to cover the plug.
- Side Discharge Chute Assembly: When using the side discharge function, the grass bag and mulching plug must be removed. The side discharge cover is lifted, and the chute is hooked into the side discharge duct. Releasing the cover secures the duct.
- Filling Engine Oil: The engine is shipped without oil or fuel and must be filled before starting. High detergent, premium quality 4-stroke engine oil (SAE30 or equivalent, e.g., SAE 10W/30) is recommended. Additives should not be used. The oil level is checked with a dipstick, ensuring it is between the Min and Max marks. The oil should be changed after the first 5 hours of use.
- Filling Engine Fuel: Clean, fresh unleaded fuel should be used. Fuel should be purchased in quantities that can be used within 30 days, and oil should never be mixed with gasoline. The fuel tank should not be overfilled, allowing for expansion. Refueling must be done outdoors in a well-ventilated area, with the engine stopped, and without smoking or open flames.
Operation:
- Starting the Engine: For a cold engine, the primer is pressed 3-5 times. For a warm engine, the primer is not needed. If the engine stops due to lack of fuel, refill and press the primer 3-5 times. The engine Start/Stop lever is pulled toward the upper handle, and the pull start is sharply pulled 4-6 inches after feeling resistance. If the engine fails to start after three pulls, the process should be repeated. Once running, the starter rope is placed into the rope guide.
- Stopping the Engine: Releasing the engine Start/Stop lever automatically switches off the engine.
- Cleaning a Flooded Engine: If the engine won't start after several pulls, it may be flooded. Release the engine start/stop lever, remove and dry the spark plug, then reinstall it (tighten 1/8 to 1/4 turn after seating). Pull the engine start/stop lever toward the upper handle and operate the pull start.
- Mowing: Select the desired cutting height (adjustable from position 1 to 7 only when the engine is off and the spark plug boot is pulled). Start the engine and set it to the required speed. Maintain a firm grip on the upper handle with the engine stop/start lever and walk with the mower.
- Working Advice: Empty the grass bag when clippings start to trail. Before removing the grass bag, switch off the engine and wait for the blade to stop. Lift the ejector flap with one hand and grab the carry handle with the other. Empty grass debris and refit the bag. Clear any grass residue or blockages in the discharge chute or mower casing using a brush or broom, never by hand or foot.
Maintenance Features:
- General Cleaning: The lawn mower should be thoroughly cleaned after each use. Dried grass and debris can impair operation. Check and remove any residual grass from the chute and underside of the mower deck.
- Spark Plug Maintenance: Once the engine has cooled, pull off the spark plug, remove it with a wrench, and clean it with a wire brush. Set the gap to 0.75mm using a feeler gauge. Install the spark plug carefully by hand to avoid cross-threading, then tighten with a spanner.
- Air Filter Service: Soiled air filters reduce engine output. The air cleaner outside cover (A) is removed, and the air filter (A) is separated from the housing (B). Inspect the filter and clean dirty filters with warm water and mild soap, allowing it to dry thoroughly before re-installation. Pressurized air or solvents should not be used to clean the filter.
- Engine Oil Change: Tilt the lawnmower towards the oil filler, place a container to catch the oil, and remove the dipstick. Once emptied, replace the dipstick and wipe clean any spillages. Refill with 17 oz./500ml SAE30 oil or equivalent. Check the oil level after running the engine briefly and topping up if necessary.
- Blade Replacement: For safety, blade sharpening, balancing, and mounting should be done by an authorized service workshop. The blade should be inspected annually. Before removing the grass bag, stop the engine and wait for the blade to stop completely. Garden gloves and a spanner wrench are needed. Do not invert the mower; tip it slightly towards the oil filler pipe. Handle the blade with care due to sharp edges. Replace the metal blade after 50 hours of mowing or 2 years, whichever comes first. Replace cracked or damaged blades. Hold the blade and unscrew the blade bolt counterclockwise. Fit a new or re-sharpened blade, locating it on the two studs on the blade flange. Replace the washer and bolts, ensuring correct location, and firmly tighten the bolt. The upturn of the blade must project into the motor compartment.
- Maintenance Schedule:
- Air Filter: Clean every 12 hours, clean every 24 hours, replace every 36 hours.
- Spark Plug: Check every 12 hours, clean every 24 hours, replace every 36 hours.
- Engine Oil: Check every 12 hours, replace every 24 hours, check every 36 hours.
- The engine oil should be changed after the first 8 hours of use.
Storing the Lawnmower:
- Short Periods (less than 15 days): Allow the engine to cool, ensure the grass bag is empty, clean all debris from under the mower deck, store on a flat and level surface upright, and in a safe place inaccessible to children.
- Extended Periods (more than 15 days): Perform storage maintenance. Empty the gas tank using a suction pump, then start the engine and let it run until all remaining gasoline is used up. Change the oil at the end of every season. Clean the cooling fins of the cylinder and the housing. Clean the entire machine to protect the paint. Store in a well-ventilated place. Do not empty the fuel tank in enclosed areas, near fire, or when smoking due to explosion and fire risk.
Transport:
Empty the gas tank and run the engine until all gas is used up. Empty the engine oil from a warm engine. Remove the spark plug boot. Clean the cooling fins of the cylinder and housing. Use the original packaging for shipping if possible.

- Engine runs unsteadily: Clean the air filter or spark plug if soiled.
- Uneven mowing results: Sharpen the blade or set the correct cutting height if the blade is blunt or cutting height is too low.
- Grass bag is not filled sufficiently: Replace the blade if worn, empty the grass bag if clogged, correct the cutting height, allow the lawn to dry if wet, clean the discharge channel/housing, or clean the underside of the mower deck if clogged.
