(c) Install the oil pan drain plug and add oil to the engine through the oil
filler port. Refer to Figure 1-15.
The weather in the area that you operate the crane determines what type of
oil to use in the engine. The oil viscosity decreases in areas of heat and
increases in areas of cold. As a result, incorrect engine oil can cause the
crane to be hard to start in a cold area. Use Table 1-2 to make a selection of
the correct type of oil for the engine.
(d) Install the oil filler cap.
(e) Operate the engine, without a load, for approximately three minutes.
Examine the area below the engine for leaks.
(f) Stop the engine and let it stand for 30 minutes. Measure the level of
oil with the dipstick. Add oil until it increases to the full mark on the
dipstick. Do not add too much oil in the engine.
