CHANGING ENGINE OIL AND FILTER
Under normal operating conditions, the engine oil and filter must be changed every 50 hours or
every 12 months whichever occurs first. Use of premium quality oil and filters is recommended.
The oil and filter should be changed more often if the engine is operating commercially or in
severe conditions such as dirty areas or during cold weather. No oil additives or break-in oil are
recommended.
ENGINE OIL LEVEL CHECK
CAUTION:
Do not operate the engine with the oil level below the ‘Add’ mark on the dipstick or
above the top or ‘Full’ mark on the dipstick.
The engine oil level should be checked daily. It is recommended that the oil be checked just
before the engine is started for the first time for the day. Because the dipstick tube has an
airtight O-ring seal you must check engine oil level by removing the dipstick, wiping it clean, and
re-inserting it.
ADDING ENGINE OIL
It is normal to add some oil in the period of time between oil changes. The amount will vary with
the severity of operation. When adding or replacing engine oil, be sure the oil meets or exceeds
the recommended specification.
ENGINE OIL QUALITY
To achieve proper engine performance and durability, it is important that you use only engine
lubricating oils of the correct type in your engine. Quality oil also provides maximum efficiency for
crankcase ventilation systems, which reduces pollution.
