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.
8. STORING AND MAINTENANCE
NOTE: Before performing any maintenance or cleaning work, switch Off the engine and wait
until the blade has come to a stop.
General cleaning
The lawn mower should be cleaned thoroughly every time after it has been used. Always clean your
lawnmower immediately after use.Donotallow grass cuttings and other debris to become dryand
hard onanyof 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 for this purpose, tilt the lawn mower onto its left
side (opposite the oill filler neck)
NOTE:
Before placing the lawn mower on its side , fully drain the fuel tank using a petrol extrac-
tion 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 plug with a twist.
2. Remove the spark plug using a spark plug wrench.
3. Clean the spark plugh with a wire brush(not supplied ).
4. Using a feeler gauge set the gapto 0.75mm
5. Install the spark plug carefully byhand, to avoid cross-threading.
6. After the spark plug is seated, tighten withthe spanner to compress the washer.
How to Service the Air Filter
As shown in Fig 20-22
Soiled air filters reduce the engine output by supply too little 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. Remove the air cleaner outside cover. Be careful to prevent dirt and debris from falling into the air
cleaner assembly.
2. Separate the air filter from the air filter housing.
3. Inspect the air filter. Clean dirty air filter with warm water and mild soap. Allow air filter todry
thoroughly before re-installation
4. Install the air filter assembly onto the carburetor and secure with screw.
NOTE:
Do not use pressurized air or solvents to clean the filter. Pressurized air ca ndamage the
filter and solvents will dissolve the filter.
Changing the engine oil
Tilt the lawnmower towards the oil filler, have a container ready to catch the oil and remove the
dipstick once the oil has been emptied, replace the dipstick and wipe clean any spillages.
Refill with 400ml SAE30 oil or equivalent i. e SAE5W/30, SAE10W/30. When the dipstick is rested on the
filler pipe (i.e. not turn in pace), the oil level must be between the min and max marks on the dipstick.
See “Checking the engine oil level and filling with engine oil”
Start the engine and allow it to run briefly.
Stop the engine ,wait one minute and check the oil level top up if necessary.
Replacing the blade
For safety reasons you should only ever have your blade sharpened, balanced and mounted by an
authorised service workshop. For optimum results it is recommended that the blade should be
inspected once a year.
WARNING: Before you remove the grass collection bag, stop the engine and wait until the
blade stops completely.

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 cutti ngheight for the first cut of the season orin drought conditions.
7. Only about one thirds of the grass height should be cut.
8. When mowing with mulching, to ensure that the cut grass can be scattered efficiently, donot cut
high or wet grass. 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 oron the blade by hand or with your feet. Instead
use suitable tools such as a brush or broom.
