Daily Maintenance Procedures - Overview
General Information
Preventative maintenance begins with day-to-day awareness of the system. Before starting the system, check the
appropriate fluid levels. Look for:
• Leaks
• Loose or damaged parts
• Worn or damaged belts
• Worn or damage low and high voltage harnesses
• Any change in system appearance.
• Odor of fuel
• Odor of electronic devices
System Operation Report
The system must be maintained in top mechanical and electronic 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 that may apply:
• 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 system 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
• Worn or damaged low or high voltage harnesses
Unusual System Noise
During daily maintenance checks, listen for any unusual
system noise(s) that can indicate that service is required.
