Assemble The Lawn Mower
WARNING!
Always take care when removing the packaging, to prevent damage to you or to
the lawn mower.
This item requires a two-person lift to remove it from the packaging. Make sure
that you have sufcient space to put the lawn mower down. Keep your feet
apart so that you have a stable position; bend at the knees and keep your back
straight.
Always recycle the packaging in accordance with local recycling schemes.
Attaching the handle
1. Rotate the quick clamp (A) 180°, fully open to disengage the quick clamp.
2. Lift the handle to the required height. NOTE: There are 3 hoses in the frame support
(B). Choose the same position on both sides to x the quick clamp.
3. Rotate the quick clamp 180° to fully engage the quick clamp.
Note: If the xation for the quick clamp is not tight enough, use a wrench to tighten the M8

Hook the cord
Pull the on/off lever and gently pull the rope. Hook it around the guide rope.
Grass bag assembly
IMPORTANT!
Make sure the grass collection bag is in place before starting the engine.
1. Attach the grass bag to the frame by xing all the plastic hooks.
2. If using the collection function, raise the safety ap and take out the mulching plug, and
hook the collection bag onto the mower. Ensure the side discharge chute is not tted
when collecting the grass in the bag. Release the safety ap.

13
Attach the cable clips
Ensure that the cable clips supplied are used to x the cable to the handle.
STOP!
Do not start the engine before putting 500ml of SAE 30 oil into
the engine.
Failure to do so will result in irreparable damage to the engine
and invalidate your warranty.

14
Preparing to Operate The Lawn Mower
Filling with engine oil
IMPORTANT!
The following procedures and adjustments must be performed before the engine
is started. Do not attempt to make any of these adjustments while the engine is
running.
This engine is shipped without oil or petrol; any oil residue is from testing prior to shipping.
The engine must be lled with the correct grade of oil and petrol before starting the engine.
Running the engine with a low oil level will cause irreparable engine damage.
Always use high-quality detergent oil classied SAE 30 oil (or equivalent, e.g. 5W 30,
often termed as 4-stroke lawn mower oil). Only use additives recommended by the engine
manufacturer. To prolong the life of your engine, it is important that the oil is changed after
the rst 5 hours of use.
Using non-detergent oil can shorten the engine’s service life, and using 2-stroke oil will
damage the engine.
Check the engine oil level with the engine stopped and the mower on a at surface.
1. Remove the oil ller dipstick and wipe it with a clean cloth.
2. Insert the dipstick into the oil ller neck, and screw it in.
3. Then remove the dipstick and check the oil level. The oil level must be between the
min. and max. marks on the dipstick. If near the lower level, ll to the upper level with
the recommended oil (SAE 30 or equivalent). Do not overll. Wipe away any spilt oil.
4. Before using for the rst time, add 0.5 litres of oil (SAE 30).

15
Filling with engine fuel
WARNING!
Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow
ames or sparks in the area where the engine is refueled or where petrol is
stored. Avoid repeated or prolonged contact with skin or inhalation of vapour.
CAUTION!
Petrol is highly ammable and extreme caution must be taken when handling or
working with it. Keep out of the reach of children.
1. Clean the area around the petrol ller cap before removing the cap. Check the fuel
level.
2. Rell the tank if the fuel level is low.
3. Always use clean, fresh unleaded petrol and purchase fuel in quantities that can be
used within 30 days.
4. Never mix oil with petrol.
5. To allow for expansion, refuel carefully to avoid overlling or spillage. There should be
no fuel in the ller neck.
6. Clean up any overow or splashes of petrol before starting the engine.
7. Tighten the ller cap after lling, nger tight only.
NOTE: The 51cm SP lawn mower has a maximum fuel capacity of 800ml.

1. Pull the lever towards the wheel, then move it forward or backward to adjust the cutting
height.
2. Move it to any one of the 7 positions for the desired cutting height.

Starting the engine
WARNING!
Do not operate the machine in enclosed or poorly-ventilated areas, as the
exhaust gas contains toxic substances. Keep hands, feet, hair and clothing
away from all the moving parts of the machine. The exhaust and other parts of
the machine will become hot during use. Make sure that the blade is securely
fastened before starting the engine.
Step 1 - Starting procedure: quick guide
step 1 step 2 step 3
To start the engine, make sure that the spark plug cap is located on the plug and the
machine is lled with sufcient oil and petrol.
Step 2 - Start/stop bar activation
Pull the start/stop bar towards you.

18
Step 4 - To stop, release the stop/start bar
Failure to start
If the engine won’t start after you have operated the starter several times, the engine
may be ooded with excess fuel. Use the following procedure to clean and start a ooded
engine:
A. Release the stop/start bar.
B. Remove the spark plug, dry it, and then reinstall it.
Install the spark plug carefully by hand, to avoid cross-threading. After the plug is seated,
tighten it 1/8 to 1/4 turns with the socket spanner to compress the washer.
C. Pull the stop/start bar towards the upper handle.
D. Operate the starter, as described in steps 2-3.
Mowing with the grass collection bag
WARNING! Always observe the strictest safety procedures when using the lawn
mower.
Start the engine and allow it to run. See ‘Step 2 - Starting the engine’.
Keep a rm grip on the upper handle and stop/start bar and push the lawn mower forward.
Walk along with it, never run with the mower. Be very careful when mowing uneven or
rough ground. Maintain a stable footing.
Mow across slopes, never up and down. Be careful when changing the direction of the
mower on a slope. Do not use the mower on a steep slope of more than 15°.
NOTE: The best result will be achieved if the grass is dry. Wet grass will tend to clog the
blade and the grass collection system.
Grass grows at different rates at different times of the year. Never use the lowest cutting
height for the rst cut of the season or in drought conditions. Only about one third of the
grass height should be cut at this time.
If the lawn mower will not collect the cuttings efciently, the grass discharge chute may be
blocked, the grass bag may be full, or the underside of the mower deck may be clogged.

19
Emptying the grass collection bag
Raise the discharge ap with one hand and remove the grass bag using its handle
with your other hand. To maintain safety, the discharge ap will close back to cover the
mulching plug when you release the ap.
Empty the grass debris in to the grass collection bag and ret the bag. If any grass residues
are caught in the discharge chute, clean it using a brush.
Mowing with the mulcher
When mulching, remove the collection grass bag, and put the plastic mulching plug into the
rear discharge chute. Then release the ap, it will close back to cover the mulching plug.
Make sure that the side discharge chute is not xed on the deck.
NOTE: To ensure that the cut grass can be mulched efciently, do not cut high or wet
grass.

20
Mowing with the side discharge
When using the side discharge to throw grass, you rst need to remove the grass collection
bag and insert the mulching plug. Follow the steps below to assemble the side discharge
chute:
1. Push the lock button with one hand;
2. Raise the side discharge cover with another hand;
3. Hold the side discharge cover open, hook the side discharge chute onto the mower
then release the discharge cover back.
