To avoid contamination of the oil samples, the tools
and the supplies that are used for obtaining oil
samples must be clean.
The sample can be checked for the following: the
quality of the oil, the existence of any coolant in the
oil, the existence of any ferrous metal particles in the
oil and the existence of any nonferrous metal
particles in the oil.

Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
NOTICE
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product. Be
prepared to collect the fluid with suitable containers
before opening any compartment or disassembling
any component containing fluids.
Dispose of all fluids according to local regulations and
mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Do not drain the engine lubricating oil when the
engine is cold. As the engine lubricating oil cools,
suspended waste particles settle on the bottom of the
oil pan. The waste particles are not removed with
draining cold oil. Drain the oil pan with the engine
stopped. Drain the oil pan with the oil warm. This
draining method allows the waste particles that are
suspended in the oil to be drained properly.
Failure to follow this recommended procedure will
cause the waste particles to be recirculated through
the engine lubrication system with the new oil.
Drain the Engine Lubricating Oil
Note:
Ensure that the vessel that will be used is large
enough to collect the waste oil.
After the engine has been run at the normal operating
temperature, stop the engine. Use one of the
following methods to drain the engine oil pan:

If the engine as an oil drain valve (3) installed,
install a suitable flexible hose onto the valve
(4). Turn the handle (2) counter clockwise and
allow the oil to drain.
b.
When the oil has drained, turn the handle
clockwise and tighten securely. Remove the
flexible hose.

3.
Install drain plug and tighten drain plug to a torque
of 34 N·m (25 lb ft).
