• If the engine must be running
to
do some work, make sure the area is well ventilated. Never run the engine in an
enclosed area. The exhaust contains poisonous carbon monoxide gas that can cause loss of consciousness and may
lead
to
death. Run the engine in an open area or with an exhaust evacuation system in an enclosed area.
• Used engine oil may cause skin cancer if repeatedly left in contact with the skin for.prolonged periods. Although this is
unlikely unless you handle used oil on
a
daily basis, it is still advisable
to
thoroughly wash your hands with soap and
water as soon as possible after handling used oil. KEEP OUT OF REACH OF CHILDREN.
• The engine must be removed from the frame before servicing the oil pump.
• When removing and installing the oil pump use care not to allow dust or dirt to enter the engine.
• If any portion of the oil pump is worn beyond the specified service limits, replace the oil pump as an assembly.
• After the engine has been installed, check that there are no oil leaks and that oil pressure is correct.
• For oil pressure indicator inspection, refer to section 19 of this manual.
