M11 Plus Series Engines Operation and Maintenance Manual – 103-999   Daily Maintenance Procedures – Overview

General Information

Preventative maintenance begins with day-to-day awareness of the engine and its system. Before starting the engine, check the oil and coolant levels. Look for:

• Leaks
• Loose or damaged parts
• Worn or damaged belts
• Any change in engine appearance.
• Odor of fuel

Engine Operation Report

The engine must be maintained in top mechanical condition if the operator is to get optimum satisfaction from its use. The maintenance department needs daily running reports from the operator to make necessary adjustments in the time allocated. The daily running report also helps to make provisions for more extensive maintenance work as the reports indicate the necessity.

Comparison and intelligent interpretation of the daily report, along with a practical follow-up action, will eliminate most failures and emergency repairs.

Report to the maintenance department any of the following conditions:

• Low lubricating oil pressure
• Low power
• Power increases or engine surge
• Erratic or no accelerator control or response
• Any warning lights flashing or staying on
• Abnormal water or oil temperature
• Unusual engine noise
• Excessive smoke
• Excessive use of coolant, fuel, or lubricating oil
• Any fuel, coolant, or lubricating oil leaks
• Loose or damaged parts
• Worn or damaged belts
