Figure 4-2. Oil Dipstick
a.
Fill the fuel tank with diesel fuel (see para. 2.5).
CAUTION
Do not overfill with oil. Engine damage could result.
b.
Refer to Figure 4-2. Make sure the engine is perfectly level. Rotate handle (1) counterclockwise until it is loose and
then remove the dipstick and fill the crankcase with approximately 0.75 quart of proper viscosity oil required by the
ambient temperature. (Refer to Appendix F.)
c.
Check the oil level by inserting the dipstick by turning handle clockwise all the way into the engine. Withdraw the
dipstick. Engine oil should coat oil dipstick within the operating range.
d.
If oil coating is below the bottom "L" mark, add sufficient oil to bring oil level within the operating range.
e.
Again check oil level to be sure oil coats dipstick within the operating range.
f.
Insert the dipstick all the way into the engine, then tighten the dipstick.
g.
Continue to step K.
h.
If oil coating extends above top "H" mark, loosen drain plug and drain enough oil to lower oil level to within the
operating range on oil dipstick.
i.
Withdraw oil dipstick and wipe with a lint-free cloth (Appendix E, item 6). Check oil level to be sure oil coats
dipstick within the operating range.
j.
Insert the dipstick all the way into the engine, then tighten the dipstick by turning handle clockwise.

Check that there is no obstruction in front of the air intake opening that might impede the flow of cooling air.
I.
Check that there is no obstruction that might hinder pull-rope action.
