Remark 1. Lubricate sparingly as required.
□ Engine oil (HD oil for service DG)
Remark 2. Refill with new heat-resistant grease
Over 32 deg F ( 0deg C )
whenever the engine is reconditioned. Lubricate
SAE 20 or 20 W
sparingly every 6000 hours
Below 32deg F (0deg C)
SAE 10 or 10 W
Remark 3. Change oil every 6000 hours. Use
Same kind of oil as in engine. Check oil level daily.
►Heat resistant ball bearing grease
Remark 4. Change engine oil. Drain off old oil when
engine is warm. Check oil level daily. USE HD OIL
“For Service DG”

Remark 1. Lubricate sparingly as required.
□ Engine oil (HD oil “For service DG”)
Remark 2. There is a lubricating hole in the
Over 32 deg F ( 0deg C )
starting motor at the flange. To lubricate, remove
SAE 20 or 20 W
screw and add a few drops at a time. Too much
Below 32deg F (0deg C)
oil can damage the motor
SAE 10 or 10 W
Remark 3. Drain off old oil when engine is warm.
Remark 4. Refill with new heat-resistant grease
Thin engine oil
whenever the engine is reconditioned. Lubricate
►Heat resistant ball bearing grease
sparingly every 600 hours.
Remark 5. Change oil in reverse-reduction gearbox
Every 600 hours. Use same oil as in engine. Check
oil level daily
