MOWING

WARNING: Always observe the strictest safety procedures when using the lawn mower. Carefully read the safety instructions of this manual before using the lawn mower.

WARNING: Never open the rear chute flap when the grass bag has been detached (to be emptied) and the engine is still running. The rotating blade can cause serious injuries!

1. Select your required height and function settings.

2. Start the engine and allow it run. See “To start the engine”.

3. Keep a firm grip on the upper handle with engine on/off control bar and self-propelled drive control bar closed and walk along with it self-propelling to start mowing.

WORKING TIPS

1. Walk, never run with the mower, and be very careful when mowing uneven or rough ground.
2. Mow across slopes, never up and down.
3. Be careful when changing the direction of the mower on a slope.
4. Do not mow excessively steep slopes.
5. The best result will be achieved if the grass is dry. Wet grass will tend to clog the blade and the grass collection system.
6. Grass grows at different rates at different time of the year. Never use the lowest cutting height for the first cut of the season or in drought conditions.
7. Only about one third of the grass height should be cut.
8. Do not cut high or wet grass when mulching to ensure that the cut grass can be scattered effectively. When you have been cutting for several minutes, please stop the mower and clean the blade and the deck.
9. Do not remove grass debris in the mower casing or on the blade by hand or with your feet. Instead, use suitable tools such as a brush or broom.

EMPTYING THE GRASS BAG

As soon as grass clippings start to trail the lawn mower, it is time to empty the grass bag.

NOTE: Before taking off the grass bag, switch off the engine and wait until the blade has come to a stop.

1. To take off the grass bag, use one hand to lift up rear chute flap and the other to grasp the grass bag handle. The rear chute flap automatically falls down after removing the grass bag and closes off the rear chute opening.

2. Empty the grass debris in the grass bag, and reinstall the grass bag.

NOTE: If any grass residue is caught in the discharge chute, clean it using a brush. Do not remove grass debris in the mower casing or on the blade by hand or with your feet. Instead, use suitable tools such as a brush or broom. To ensure that the cut grass can be collected into grass bag, the discharge opening and inside the mower casing must be cleared of any blockage.

MAINTENANCE AND STORAGE

WARNING: Before performing any maintenance or cleaning work, switch off the engine and wait until the blade has come to a stop.

CLEANING

GENERAL CLEANING

The lawn mower should be cleaned thoroughly every time after it has been used. Always clean your lawn mower immediately after use.

Do not allow grass cuttings and other debris to become dry and hard on any of the mower surfaces.

Dried grass remnants and dirt may impair the mowing operation.

Check that the grass chute is free of any residual grass. Remove any such residue. Check the underside of the lawn mower and the blade mount. When checking, tilt the lawn mower onto its left side (opposite the oil filler neck).

NOTE: Before placing the lawn mower on its side, fully drain the fuel tank using a gas extraction pump.

Do not tilt the lawn mower by more than 90 degrees.

MAINTENANCE OF THE SPARK PLUG

As shown in Fig. 19

1. Once the engine has cooled, pull off the spark cover with a twist.
2. Remove the spark plug using a spark plug wrench (not supplied).
3. Clean the spark plug with a wire brush (not supplied).
4. Using a feeler gauge, set the gap to 0.027"- 0.033" (0.686- 0.838 mm).
5. Install the spark plug carefully by hand to avoid cross-threading.
6. After the spark plug is seated, tighten with the spark plug wrench to compress the washer.

MAINTENANCE OF THE AIR FILTER

As shown in Fig. 20

Soiled air filters reduce the engine output by restricting air to the carburetor. If the air contains a lot of dust, the air filter should be checked more frequently.

WARNING! Never run the engine without the air filter element installed.

1. Press tabs at the top of the air filter cover and tilt away from the engine to remove the cover.
2. Remove the filter cartridge.
3. To loosen debris, gently tap the filter cartridge on a hard surface. If the filter cartridge is excessively dirty,
replace with a new one.
Note: Never clean the air filter cartridge with gas or inflammable solvents.
Clean the air filter cartridge only with compressed air or by tapping it.
4. Install the filter cartridge.
5. Close the cover and secure it properly by snapping tabs back into the correct slots at the top.

CHECK AND ADD THE ENGINE OIL

The Briggs & Stratton 675EXi engine on this lawn mower is made with a special feature Check & Add(TM). The oil never needs to be changed. Before each use check the oil level and add additional oil if the level is not within the Min - Max levels.

REPLACING THE BLADE

For safety reasons you should only ever have your blade sharpened, balanced and mounted by an authorized service workshop. For optimum results, it is recommended that the blade be inspected once a year.

For safety reasons we recommend that the blade only be changed by someone qualified and authorized to do so.

Hold the blade and unscrew the blade bolt counter-clockwise using a wrench. Remove the washer and the blade.

Fit a new blade or re-sharpen the blade. Place the blade on the two studs on the blade flange and then replace the washer and bolts. Make sure the blade is correctly located, and then firmly tighten the bolt. Do not over tighten. The up turn of the blade must project into the motor compartment.

STORING THE LAWN MOWER FOR SHORT PERIODS

The lawn mower can be stored for short periods of time (less than 15 days) without performing any storage maintenance. Before placing the lawn mower into storage always do the following:

1. Allow the engine to fully cool.
2. Ensure the grass bag is empty.
3. Clean all debris from under the mower deck.
4. Store the lawn mower on a flat and level surface with the mower upright.
5. Store in a safe place which is not accessible by children or people who are not familiar with the lawn mower's operation.

STORING THE LAWN MOWER FOR EXTENDED PERIODS

If the lawn mower is to be placed into storage for more than 15 days, storage maintenance must be performed on the lawn mower. If the following steps are not carried out, when you next operate the lawnmower it may not start correctly and may need to be serviced.

CAUTION! Do not empty the gas tank in enclosed areas, near fire or when smoking. Gas fumes can cause explosions and fire.

1. Empty the gas tank with a gas suction pump if available.
2. Start the engine and let it run until any remaining gas has been used up.
3. Clean the cooling fins of the cylinder and the housing.
4. Be sure to clean the entire machine to protect the paint.
5. Store the machine in a well-ventilated place.
