CAUTION! Initial oil fill requires less oil due to residual
oil in engine from the manufacturers 100% quality
testing. When changing oil you need a larger oil
quantity than the initial fill.
Add oil
1 The lawn mower should stand on flat ground when
you check the oil level. Ensure the ignition lead is
disconnected from the spark plug before you open the
oil filler cap.
2 Remove the oil cap and wipe the dipstick clean.
3 Slowly pour oil down the oil fill spout, stopping evey
few ounces to check the oil level with the dipstick.
4 Stop adding oil when you reach the FULL mark on the
dipstick. Wait a minute to allow oil to settle.
5 Always be sure to retighten oil dipstick before starting
engine.
6 Connect the ignition lead to the spark plug.
Oil change
CAUTION! The oil level must always be checked before
starting the engine.
Clean more often if conditions are exceptionally dusty.
Follow the maintenance schedule in this manual.
1 Disconnect the ignition lead from the spark plug.
2 Always empty the fuel tank before you place the lawn
mower on its side. Empty the fuel tank by running the
machine until the tank is empty.
3 Unscrew the oil filler cap.
4 Place a suitable vessel in position to collect the oil as
it drains.
5 Drain the oil by tipping the engine so that the oil runs
out through the filler pipe. When the machine is tilted,
make sure the air filter always is placed in the highest
position. Ask where you can dispose of surplus
engine oil at your local gas station.
6 If you have spilled fuel or engine oil on the machine,
wipe off the spillage and allow remaining fuel to
evaporate.
7 Slowly pour oil down the oil fill spout, stopping evey
few ounces to check the oil level with the dipstick. Do
not overfill!
8 Always be sure to retighten oil dipstick before starting
engine.
9 Connect the ignition lead to the spark plug.
Muffler
If the muffler is corroded or is damaged in any other way,
it must be replaced because it may become a fire hazard
and/or cause injury.
Spark plug
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the
piston/cylinder.
• Replace spark plug at the beginning of each mowing
season or after every 100 hours of operation,
whichever occurs first. Spark plug type and gap
setting are shown in the ”Product specification”
section of this manual.
Air filter
Your engine will not run properly and may be damaged by
using a dirty air filter. Replace the air filter cartridge every
100 hours of operation or every season, which ever
occurs first. Service air cleaner more often under dusty
conditions.
• Remove the air filter cover and take out the filter.
• Clean the filter by knocking the filter against a flat
surface. Never use solvent with petroleum, for
example, kerosene, or compressed air to clean the
filter.
• An air filter that has been in use for a long time cannot
be cleaned completely. The filter must therefore be
replaced with a new one at regular intervals.
A
damaged air filter must always be replaced.
• When reassembling, make sure that the filter
completely seals against the filter holder.
