Engines fitted to rotary
lawnmowers are shipped without oil. Check the
engine manufacturers manual for oil grade
details.
CAUT
I
O
N
Petrol vapour is highly
flammable. Handle with extreme care. Store in
approved containers.
Oil: Before you use your lawnmower, every
four stroke will require approximately 600
ml of engine oil in the sump. With the
lawnmower in a level position,
1. Remove the oil dipstick.
2. Wipe the dipstick clean.
3. Fill to the full mark, pouring slowly - DO NOT
OVERFILL. Then screw the dipstick securely
back into place.
Note that if the engine is overfilled, it will smoke
excessively or appear to be seized.
Fuel: Your engine will run best on fresh, clean
unleaded petrol (91 octane). Use of
unleaded fuel results in fewer combustion
deposits, burns cleaner and gives longer
valve life.
Do not fill the petrol tank too full to allow for fuel expansion. It is recommended that
approximately 5mm to 10mm of tank space is left for this.
When handling fuel: - Do not fill tank when the engine is running.
- Do not smoke or expose naked flame.
- Do fill tank in open well-ventilated area.
- Do wipe away any spills.
- Do move the mower away from any petrol fumes before starting
engine.

stopped and the blade has stopped rotating
before fitting or removing the Mulcher plug.
Handlebar folding instructions:
The handlebar assembly is supplied in the storage
position for packaging purposes. The folding handle
system allows for compact storage when not in use.
Unfold the handle by lifting and turning it to its
‘mowing’ position.
Lock the handlebar in this position before operating
the mower by activating the locking lever. The
locking lever can be locking in place at any point
throughout its 360-degree movement.
On models fitted with ‘zone start’ facility, pull the
engine starter cord out carefully so that there is
sufficient length to extend the handle fully without
stretching the cord.
To change the handlebars back to the storage position,
simply loosen the handle locking lever and rotate the
upper handlebar forward over the mower body.
Handlebar Height adjustment instructions:
The height of the handlebar can be adjusted to various
heights.
Lift the grass flap and secure it in the open position, loosen the four bolts two on each side
holding the handle to the mower.
The handle can now be adjusted to the correct height by moving it.
Hold the handle in place and tighten the bolts to secure the handle in its new position.
To adjust the handle height on the 530 self propelled models, you must first remove the
cover to the gearbox area.
Mulch & Catch models: The mulching lawnmowers have been
assembled ready for mulching mode. They
have the mulching plug inserted and the
correct blade system fitted. Removal of the
mulcher plug and fitting the catcher converts
the mower to a catching model and vice
versa.
NOTE: The 530SPB has no mulch option

Never start or run the engine
indoors or poorly ventilated areas, engine
exhaust contains carbon monoxide gas, which can
be fatal. Keep hands, feet, and clothing away from
moving parts.
Starting the lawnmower - cold starts: Open the fuel shut off valve (where fitted).
Move the throttle control to choke / start
position. For lawnmowers fitted with non-
choke engines, the primer bulb must be
firmly pressed three to four times after the
throttle control lever has been moved to the
run position.
1. Grasp the starter grip and pull slowly until resistance is felt and then pull the starter cord
with a rapid, smooth movement to start the engine. Do not allow the cord to snap back.
2. For models without a ‘zone start’ feature, place your foot against the mower body then
grasp the starter grip.
3. Repeat the starting procedure above if necessary.
4. When the engine starts, move the throttle to the run position and to the speed desired.
5. In the case of flooding occurring, move the throttle to the stop position, pull the starter cord
5 - 6 times, then move the throttle lever to the choke / start or run position and pull the
starter cord as above.
Starting the lawnmower - hot starts:
Follow the above #1 to #5 steps for restarting after emptying catcher or short rest periods. A
warm engine will usually start in the idle position. However, if it fails to start, follow the cold start
procedure.
Stopping the engine:
To stop the engine, move the throttle control to the stop position. Turn the fuel shut-off valve
(where fitted) to the close / off position when the mower is not in operation to prevent fuel
leakage from the carburettor.

Throttle control lever:
The throttle control lever is located
on the right hand handle for the
530SPB models.
The throttle lever is moved fully
forward into the detented choke /
start position to start a cold engine.
The run position has a detented
position for working (or governed)
speed and a graduated quadrant
slide allows for selected slower
running speeds. Note that the engine speed dictates the speed and operation of the cutting
system.
Zone Start handle:
Note that as soon as the engine is cranked the cutting blades rotate immediately. Models fitted
with Zone Start allow effortless, trouble free, at the handle starting while keeping feet and hands
away from the cutting mechanism and danger zones. To start simply pull the zone start handle
firmly as you push the mower handlebar away.

The single lever height adjustment makes for easy change from one height setting to another.
There are ten height of cut settings available (from 10 mm to 65 mm) and the most suitable
height should be selected that best suits the grass and weather conditions. To adjust the height
of cut setting, follow the steps below.
Grip the height adjust lever by the black knob.
Apply an outward force to the lever to disengage it from the quadrant rack setting.
Holding the lever out, move the lever up
or down the quadrant rack to the desired
height of cut.
Engage the lever into the quadrant rack
by releasing the outward force.
Note that when using a mulching lawnmower,
using the higher height settings will give the
best mulching performance.
There are two holes in the axle bell cranks on
the left hand side of the mower. The correct
setting for the connecting rod link is to have
the rear of the link in the top hole and the front
of the link in the lower hole.
Cutting blade adjustment:
It is essential that the relationship between
the blade(s) and mower body is kept in good
adjustment and that cutting edges are kept
sharp to ensure good cutting performance,

power consumption and prolonged life for the cutting edges. Carry out the following procedures
before commencing work and re-check the settings every 2 to 3 hours of mowing or when the
cutting performance is noticeably reduced. During mowing, the blade tips can move relative to
the mower body through normal work or by hitting obstructions. Check that the cutting blade(s)
is correctly set to the mower body by measuring the distance the blades are inside the
lawnmower skirt, this distance should nominally be 3 mm. Disconnect the spark plug cable and
carefully rotate the blade by hand and check that the distance is nominally correct all around the
mower body. If adjustment is necessary, proceed as follows
Remove the spark plug cable from the spark plug.
Rotate the blade(s) until it is accessible from the rear flap area.
Re-fit the spark plug cable.
If it is impossible to obtain a good clean cut, it may be necessary to take the mower to your local
Service Agent to have a new set of blades fitted.
Grass catcher:
Your rotary lawnmower can be operated with
the grass catcher fitted, or removed as a
utility mower.
Note that if the lawnmower is used with the
catcher removed, the rear flap must be fitted and located in the down / closed position. To fit the
grass catcher, stop the engine and position the catcher on the ground behind the mower. Raise
the rear flap and lift the catcher into position ensuring the catcher tongue is located over the
rear axle. Slide the catcher forward and upward; lower the flap so that the lugs on the flap locate
into the square holes on top of the catcher. Your catcher is now attached.

OPERATING THE LAWNMOWER.
To remove
the grass catcher, stop the engine, hold the catcher by its top handle raise the rear flap. Lift the
grass catcher up and away from the lawnmower and return the grass flap to its down / closed
position.
Avoid leaving the catcher in direct sunlight when not in use. The catcher will not deteriorate if
stored wet but prolonged exposure to sunlight can cause premature UV breakdown. Dust and
clippings will build up inside the catcher and on its venting screen, particularly during wet
weather mowing. This debris will impede the function of the catcher so it should be removed by
hosing out with water when necessary.

Running engines, fitted to
rotary lawnmowers, without sufficient oil can
cause the engine to seize.
Engine:
Refer to the manufacturers operator owner manual for engine maintenance information.
Check engine oil level: Periodically the oil level should be checked
to ensure it is correct. Engine oil also
requires changing after the initial first five
hours of use, and then every 50 hours of
normal use and 25 hours of heavy use
thereafter. With the mower in a level position,
1. Remove the oil dipstick.
2. Wipe the dipstick clean replace and
remove.
3. If the engine oil level is below the minimum
mark on the dipstick, top up with the
correct grade of engine oil to the full mark
on the dipstick. DO NOT OVER FILL. Then
screw the dipstick securely back into place.
Note that if the engine is overfilled, it will
smoke excessively or appear to be seized.
Clean the air cleaner:
Remove and clean the air filter cartridge at three monthly intervals or every 25 hours of normal
use. The air filter cartridge may require servicing more often under dusty or commercial
operating conditions. To service the air cleaner cartridge, follow the procedures detailed in the
engine manual.
12

MAINTENANCE
Check spark plug:
Clean and reset the spark plug gap every 25 hours of operation. Remember, in small engines,
difficult starting and erratic running is most often
attributable to a dirty, oily or carbonated spark plug.
Do not file or sand blast the spark plug electrode but
clean by scraping or wire brushing, then cleaning with
a commercial solvent. Clean and reset the spark plug
gap at 0.7 - 0.8mm (0.030”) every 100 hours of
operation.
Always fit the recommended spark plug.
Rotating screen:
Through prolonged operation, the rotating screen may become clogged with grass and debris.
Clean the screen in line with the engine manufacturers recommendations to avoid over heating
and possible engine damage.
Throttle control & Self Propelled control:
Lubricate the cable every 25 hours of mowing by applying a light oil to the top of the inner wire
and allowing it to gravity drain down the inside. The throttle control lever quadrant should have
medium grease smeared over it to protect it from corrosion and to give a smooth operation.
Fasteners and linkages:
Check that all nuts, bolts, pins and linkages are secured correctly in place and are in good
condition.
Blade Care:
Check the condition of the blades, bolts and cutter assembly regularly. Remember that badly
worn blades will affect grass cutting, catcher fill and cause excessive mower vibration.
Change Worn or Damaged Blades:
It is recommended that you use an authorised Service Agent for any replacement or balancing
blade work. Always fit a complete set of blades and fasteners to maintain balance

Care should be used when
cleaning around the muffler, ensure that the
muffler is cool enough to touch before cleaning.
Cleaning the Mower Body:
There is a direct relationship between the lawnmower’s life and the care and attention given to
the lawnmower both during and after operation. After use it is important that the lawnmower is
thoroughly cleaned down and inspected so that it will be in good working order the next time it is
required. Disconnect the spark plug lead and thoroughly clean the engine, underside of the
chassis, wheels and grass catcher.
Your rotary lawnmower features a wash nozzle
for easy cleaning of the underside of the body.
Simply run the lawnmower at a moderate speed,
place a garden hose into the wash nozzle and
turn on the water supply for two to three minutes.
The action of the rotating blade system will
dislodge most grass and debris build up.
Cleaning the Catcher:
Simply hose out the catcher and screen after each use to ensure maximum mower performance
and catcher fill.
Muffler:
Always clean around the muffler area regularly to reduce the risk of fire and damaging the
mower. Brush the grass, dirt or combustible debris from the muffler.
