SAFETY INSTRUCTIONS
Read and understand the owner’s manual and labels afxed to
the lawn mower. Learn its application and limitations as well
as the specic potential hazards. Retain these instructions for
reference.
• Use sturdy footwear - do not operate when barefoot or wearing
open sandals.
• Do not put handsor feet near or under rotating parts. Keep clear of
the discharge opening at all times.
• Do NOT operate the lawn mower if you are tired, ill or under the
inuence of alcohol or drugs.
• Do NOT smoke when using the lawn mower and ensure caution
when handling fuel. We recommend you fuel the machine away
from where you wish to work in case any spilt fuel ignites when
starting the engine.
• Ensure that bystanders, children and pets stay at a safe
distance when mowing and only allow persons familiar with these
instructions to use the lawn mower.
• Inspect the lawn mower, and in particular the blade, before use for
any worn or damaged parts. Do not use until the parts are repaired
or replaced with parts approved by the manufacturer.
• Before starting the engine make sure the lawn is clear of obstacles
such as stones, branches or children’s toys.
• Always stop the engine when crossing gravel drives, walks or
roads. Stop the engine and allow the blade to stop rotating
before removing the grass bag.
• Stop the engine and disconnect the spark plug before clearing
blockages, cleaning or inspecting the mower.
• Do not operate when raining and take particular care on damp
grass which can prove slippery, particularly on slopes.
• When mowing on a slope always mow across the slope, not up
and down. Take care when changing direction. The slope should
not exceed 20 degrees.
• Clean the mower after each use and, if storing for a prolonged
period, drain the fuel in the tank. Remove the spark plug
and put a few drops of oil into the cylinder before pulling the
starter a couple of times to distribute the oil evenly. Replace the
spark plug. If you need to tilt the mower while cleaning always tip it
backwards towards the handles, do not tip it on its side as this will
cause oil to enter the carburettor or exhaust.

ASSEMBLY AND OPERATION
The lawn mower is shipped without oil or petrol in the
engine.
The mower has been assembled and tested in the factory and
only needs a small amount of assembly.
 Remove the lawnmower carefully from the box - it may be
easier to remove one side of the box and roll the machine
out.
 Depress the Brake Lever, unfold the handles carefully so as
not to pinchthe cables then raise the lower handles. Fit the
two bolts and wingnuts from the parts bag, which will lock the
lower handle into place. Raise the upper handle section so
that it lines up with the lower handle section. Tighten the
wingnuts.
 The diagram shows the position of the three parts of the
upper handle.
 The brake lever (sometimes called the operator presence
control lever) must be pulled back towards the handle to
start the engine and during operation. If the lever is
released it will automatically stop the engine.
 The drive control lever - pull this lever up towards the han-
dle to engage the self-propelled mode. If this is not engaged
the mower can be used in ‘push’ mode.
 The engine speed has been set at the factory for optimum
performance - it is not adjustable.
 The cutting height can be adjusted by a single lever through
7positions from 25-75mm. The medium position is best for
most lawns. Under certain conditions, such as very tall grass,
it may be necessary to cut the grass twice, once on the
highest setting and then again on medium.
Operation:
 Fill the engine with SAE30 oil to the ‘full’ mark on the
dipstick. Check the level of the oil.
 Fill the fuel tank with unleaded petrol.

 Pull the brake lever back to the push handle and pull the
starter cord until resistance is felt, then pull rapidly to start the
engine.
Note: if the brake lever is released the engine will stop.
 Pull the drive control lever up towards the handle and the
lawnmower will self-propel.

OPERATION cont’d
The mower has four different operating modes.
1. Collecting:
• Ensure that the side cover is closed.
• Fit the grassbox by lifting the rear ap on the mower and hook
the front of the box to the shaft on the mower.
• Lower the ap to lock the grassbox in position.
• When the box isfull, the grass will be visible through the viewing
window in the top of the box.
• Stop the engine before emptying the grassbox.
2. Rear Discharge:
• Ensure that the side cover is closed.
• With the grassbox removed and the rear ap in the down positi-
on, the mower will cut and discharge the grass from the rear of
the machine.
3. Side Discharge:
• Fit the mulch plug to the rear discharge opening of the mower
and close the rear ap.
• Lift the cover on the side of the mower and attach the side dis-
charge chute as shown in the diagram.
• The mower will now eject grass from the side discharge chute.
4. Mulching:
• Fit the mulch plug to the rear discharge opening of the mower
and close the rear flap.
• Ensure that the side cover is in the closed position (with the
discharge chute removed).
• The mower will now recycle the chopped grass into the lawn
surface.
• To mulch efciently only cut one third of the length of the grass.

MAINTENANCE
Regular careful maintenance is essential for keeping the lawn-
mower in tip-top condition.
• Before each use, ensure that all bolts, nuts and screws are
tight.
• After each use, allow the mower to cool down before clean-
ing off any grass and other debris. Use a brush or com-
pressed air and avoid getting water into the engine.
• Never store the mower with petrol in the tank within an en-
closed area where it is possible for fumes to reach an open
ame or spark.
• When storing for a long period drain the mower of fuel after
the engine has cooled down. Do this outside to reduce any
risk of re from spilt fuel.
• Change the oil after the rst 5 hours and thereafter every
season or every 50 hours. Dispose of waste oil at your local
recycling centre.
• Clean the spark plug regularly and change every season.
To change the blades:
• Drain the fuel tank by running the mower until the fuel tank
is empty and the engine stops.
• Allow the engine to cool and then tip on to its left hand side
(air cleaner side uppermost).
• Using gloves to protect your hands, undo the screw and re-
move the old blade and replace with a new one in the order
shown on the diagram.
• Tighten the screw to the specied torque of 45 Nm.
A damaged blade that is out of balance will cause the
mower to vibrate and may break. Check the condition of
the blade regularly.
