The MACK Preventive Maintenance and Lubrication program outlined in this manual is designed to ensure a long and productive life from your truck. The program is divided into four maintenance schedules, each addressing items which require periodic inspections to ensure efficient, reliable and trouble-free operation. To allow flexibility in developing a maintenance routine suitable to your operating requirements, maintenance intervals in this manual are arranged in miles/kilometers, hours or days of operation. Maintenance instructions, specifications and capacities are outlined for quick and easy reference. The service manager at your MACK distributor will be happy to assist in customizing a maintenance program tailored to your operating requirements
Following the MACK Preventive Maintenance Program is highly recommended to all operators of MACK vehicles because it is the key to lower operating costs both in time and money. The bottom line to a well-run maintenance program is less downtime and increased profitability.
MACK cannot anticipate every possible occurrence which may involve a potential hazard. An accident can be avoided by recognizing potentially hazardous situations before an accident occurs. Correctly performed service procedures are critical to technician safety and the consequent safe, reliable operation of the vehicle.
ADVISORY LABELS
Cautionary signal words (Danger-Warning-Caution) may appear in various locations throughout this manual. Information accented by one of these signal words must be observed to minimize the risk of personal injury to service personnel, or the possibility of improper service methods which may damage the vehicle or cause it to be unsafe. Additional Notes and Service Hints are used to emphasize areas of procedural importance and provide suggestions for ease of repair. The following definitions indicate the use of these advisory labels as they appear throughout the manual.
VEHICLE BREAK-IN
Although your new truck has been quality built, inspected, lubricated and final adjustments performed at the MACK Trucks Assembly Plant, an occasional air, oil or coolant leak may develop. Quick action to correct these minor items will prevent a major repair later. Take your truck to the nearest MACK service center as soon as any abnormal condition becomes evident.
Driver’s Daily Inspection
Before beginning the day’s operation, make a “walk around” inspection of your truck. The following checklist provides an aid in making a thorough inspection and ensures no item will be overlooked. Make sure any problem is corrected before using the vehicle.
Mack Preventive Maintenance and Lubrication Program
Your MACK chassis was designed and built with performance, durability and productivity in mind. The MACK Preventive Maintenance and Lubrication programs were developed to maintain your chassis and keep it running the way it was designed to run. Preventive maintenance, not breakdown maintenance, is the key to many years of trouble-free operation.

Line Haul 2 - Regular Service Interval - High Mileage Operations exceeding 100,000 miles (161 000 km) per year that do not meet ALL of the requirements for Line Haul 1 - Extended Service Interval. Many operations in this category can base service intervals on accumulated chassis mileage. However, vehicles used for pump-off or similar types of service where the engine idles for long periods of time, require oil change intervals based on hours of engine operation rather than accumulated chassis mileage, even if vehicle usage exceeds 100,000 miles (161 000 km) per year. Engine operating hours must not exceed 700 hours between oil changes. EO-M PLUS specification diesel engine oil is recommended.
Short Haul - Severe Service Interval - Low Mileage/High Hour types of operations such as stop-and-go driving, on/off highway, pick-up and delivery, pump-off operations, etc. EO-M PLUS specification diesel engine oil is mandatory.
Refer to tables on pages 15, 18 and 21 and choose the schedule which best fits your type of operation. For ease of planning, schedules are based on mileage/kilometers or days/hours of operation. Other factors which must be considered are environment, climate, engine idling, usage of engine-driven auxiliary attachments, etc. The service manager at your MACK dealer will be happy to assist in tailoring a maintenance program for your particular operating requirements.
