Prevent damage to your
lawnmower through regular
maintenance
Regular maintenance is essential for the continued
safe operation of the mower. Correct servicing will
prolong its working life and safeguard the Dual
Drive Warranty. Always fit genuine LawnMaster
Dual-Drive Service Parts as these are accurately
matched to the required duty.
Engine
Refer to the Engine Manufacturer's Operators' manual
for engine maintenance information.
Fuel
If the fuel has to be drained for maintenance or any
other reason, this should be done outdoors.
Reel mower (running) engines
can seize without sufficient oil
Check engine oil level
Before the first use, every Dual-Drive mower will
require 600ml of engine oil, as it leaves its point of
manufacture in a 'dry' condition. Engine oil requires
changing after the 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,
remove the filler cap/dipstick. If the engine oil level is
below the minimum mark on the oil dipstick, top up
with the correct grade of engine oil to the full mark on
the dipstick. DO NOT OVER FILL. Then screw the filler
cap/oil dipstick securely back into place.
Clean the air filter
Remove and clean the air filter cartridge at 3 month
intervals or every 25 hours of use. The air filter
cartridge may require servicing more often under dusty
operating conditions.
To service the air filter cartridge proceed as follows...
Maintenance
•
Loosen the screws and remove the cartridge.
•
Blow a gentle air line through the cartridge in the
opposite direction to normal engine operation.
•
If the cartridge is excessively dirty, it should be
replaced.
Check spark plug
Clean and reset the spark plug gap every 100 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.
Rotating screen
Through prolonged operation, the rotating screen,
located on top of the engine, may become clogged
with grass and debris. Clean the screen in line with the
Engine Manufacturer's recommendations to avoid over
heating and possible engine damage.
Throttle control
Lubricate the throttle cable 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 a medium grease smeared over it to protect
it from corrosion and to give a smooth operation.
Clutch cables and pivots
Lubricate the clutch cable by applying a light oil to the
top of the inner wire and allowing it to gravity drain
down the inside. The cable pivot also requires occasional
lubrication to allow free movement of the mechanisms.
Fasteners and linkages
Check that all nuts, bolts, pins and linkages are secured
correctly in place and are in good condition.
Drive chain tension
It will be necessary after the first 5 hours and every
25 hours of use thereafter to check and adjust the
tension of the drive chains. The chain guard, located
on the side of the cylinder, must be removed from the
