Change Oil – Splash Lube Engines
The crankcase capacity of twin cylinder engines
without oil filters is approximately three pints.
NOTE: Early production engines had approxi-
mately 3-1/2 pint (1.65 liter) oil capacity.
Use dipstick to check oil level.
IMPORTANT: DO NOT OVERFILL. Check and main-
tain oil level regularly. Change oil after first eight (8)
hours of operation.
Thereafter, change oil every fifty (50) hours of opera-
tion. Change oil more often if engine is operated in dirty
or dusty conditions or if engine is operated under
heavy loads or in high ambient air temperatures.
Remove oil drain plug and drain oil while engine is still
warm, Fig. 1 and Fig. 2. Replace drain plug.
Remove dipstick and refill slowly with new oil of proper
service classification and viscosity grade. Refill to full
mark on dipstick. When checking oil level, dipstick
must be screwed all the way in for accurate readings.
Start and run engine to check for oil leaks.
