VII. SERVICE AND MAINTENANCE

Fluids

Engine oil

OIL LEVEL - The engine oil level dipstick is located on the left-hand side of the engine (fig . 7.1, item 1). Never operate the engine with the oil level below the “L” (low) mark or above the “H” (high) mark. Wait at least five minutes after shutting off the engine to check the oil level; this allows time for the oil to drain to the oil pan. Check the engine oil level daily, change it yearly or every 500 hours.

CAPACITY - Low to high mark capacity is 2.0 quarts. Engine oil pan capacity (including filter) Is 17 quarts (SAE 15W 40).

NOTE:

The engine must be level when checking the oil level to make sure the measurement is correct.

Hydraulic Oil Reservoir

OIL LEVEL - Check the hydraulic oil level in the reservoir using the dipstick daily (fig. 7.2). Add just enough fluid so the level reaches the bottom tip of the dipstick. Hydraulic oil will expand when heated in a system, and measuring the reservoir by these levels allows for expansion. Always check the hydraulic oil level when it is cool and with lift cylinders in lowered position.

TYPE - Premium hydraulic fluids containing high quality rust/ oxidation/and foam inhibitors are required. Hydraulic oil must conform to one of the following types: anti-wear hydraulic oil, type F automatic transmission fluid, or agricultural hydraulic transmission fluid. Replace the oil in the hydraulic reservoir at 500 hours or at the beginning of each detasseling season, whichever comes first.
