CAUTION! Initial oil fill requires less oil due to residual 

oil in engine from the manufacturers 100% quality 

testing. When changing oil you may need a larger oil 

quantity. .

Add oil

1  The lawn mower must 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.
Follow the maintenance schedule in this manual. Clean 
more often if conditions are exeptionally dusty.

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. 

damaged air filter must always be replaced.

•  When reassembling, make sure that the filter 

completely seals against the filter holder.
