OPERATIONAL PERFORMANCE TEST / Engine Test LUBRICANT CONSUMPTION Measuring Method 1. Place the machine on level firm ground and leave the machine for at least one hour in order to let the lubricant lower to the oil pan when the engine stops. At this time, confirm that the machine is level by using a leveler. 2. Record read-out A (unit: hour) of the hour meter. 3. Replenish the lubricant up to the high-level gauge. 4. Operate the machine for at least 100 hours or un- til the oil level lowers to the low-level gauge. IMPORTANT: Keep the machine-leaving time in Step 1 above. 5.

At this time, confirm that the machine is level by using a leveler. 6. Record read-out B (unit: hour) of the hour meter. 7. Replenish the lubricant up to the high-level gauge while measuring the oil-replenishing vol- ume C. NOTE: When measuring, use a high-precision measuring cylinder or the like. 8. Determine lubricant consumption from the fol- lowing equation: Oil replenishing volume (C) [mL] / Operating hours (B-A) [hr] Evaluation: Refer to Operational Performance Standard in Group T4-2. T4-3-8
