Checking and Changing Engine Oil
The product is NOT supplied with engine oil, although traces of oil from the
manufacturing process may be present. It is essential to add adequate engine oil of the
correct type to the engine before use.
Failure to add engine oil will void the product warranty
. •
Always check engine oil level when the machine is in an upright position on a flat and level surface. •
Do not use used or contaminated engine oils. • Use only engine oils of the correct type (see
Specifications
). • Perform the first oil change within the first 20 hours of use. Subsequently, change the
oil every 20 hours of use. • It is recommended that the engine be warm, but not hot, when performing oil
changes. When the oil is warm it drains faster. • Using dirty or incorrect engine oil may cause engine
damage and void any warranty • Always use suitable tools. • Always dispose of used oil in an
environmentally responsible manner and according to regulations.
Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe
or irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level
requires regular maintenance as per the maintenance schedule.
To check engine oil level:
1. Place the machine in an upright position on a flat and level
surface.
2. Clean the machine around the oil filler cap (
A
) so that no dirt or
other material enters the engine when the cap is removed.
3. Remove the oil filler cap (rotate left) until fully unscrewed. For
machines without a dipstick, the oil level is determined by how
close the oil is to the filler hole (
B
). The lower limit is indicated by
(
X
), the upper limit by (
Y
). For machines equipped with an oil level
dipstick:
a. Wipe the dipstick (
C
) clean with a piece of cloth or paper.
b. Insert the dipstick into the oil filler but do not screw it in.
c. Remove and inspect the dipstick – the oil level is determined
by where oil can be seen on it.
4. Ensure that the oil level is at or just under the permissible maximum. If the oil level is low, add
additional oil until the correct level is reached. If the oil level is too high, drain some oil until the
correct level is reached.
5. When finished, reinstall (rotate right) the oil filler cap until firm. Wipe off any residual oil from the
machine.
