Safety
The safety section lists basic safety precautions. In addition, this section identifies the text and locations of warning signs and labels used on the machine.
Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance and repair on this machine.
Operation
The operation section is a reference for the new operator and a refresher for the experienced operator. This section includes a discussion of gauges, switches, machine controls, attachment controls, transportation and towing information.
Photographs and illustrations guide the operator through correct procedures of checking, starting, operating and stopping the machine.
Operating techniques outlined in this publication are basic. Skill and techniques develop as the operator gains knowledge of the machine and its capabilities.
Maintenance
The maintenance section is a guide to equipment care. The Maintenance Interval Schedule (MIS) lists the items to be maintained at a specific service interval. Items without specific intervals are listed under the "When Required" service interval. The Maintenance Interval Schedule lists the page number for the step-by-step instructions required to accomplish the scheduled maintenance. Use the Maintenance Interval Schedule as an index or "one safe source" for all maintenance procedures.
Maintenance Intervals
Use the service hour meter to determine servicing intervals. Calendar intervals shown (daily, weekly, monthly, etc.) can be used instead of service hour meter intervals if they provide more convenient servicing schedules and approximate the indicated service hour meter reading. Recommended service should always be performed at the interval that occurs first.
Under extremely severe, dusty or wet operating conditions, more frequent lubrication than is specified in the maintenance intervals chart might be necessary.
Perform service on items at multiples of the original requirement. For example, at every 500 service hours or 3 months, also service those items listed under every 250 service hours or monthly and every 10 service hours or daily.
California Proposition 65 Warning
Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.
Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.
Certified Engine Maintenance
Proper maintenance and repair is essential to keep the engine and machine systems operating correctly. As the heavy duty off-road diesel engine owner, you are responsible for the performance of the required maintenance listed in the Owner Manual, Operation and Maintenance Manual, and Service Manual.

The maximum level mark on the lubrication pump
• Fill the reservoir up to the maximum level that is indicated on the reservoir.
• Remove the filler hose and fit the dust cap.
• Place the filler hose back in the hose's proper place in order to ensure that the coupling of the filler hose remains clean.
Note: Every 500 service hours replace the filter or every 500 service hours clean the filter for the filler on the lubrication pump. The filter is behind the connector on the reservoir.
Note: If the pumping action seems to go heavy, check the filter behind the coupling for the filler on the lubrication pump. Gently clean the filter or replace the filter. If the filter is damaged, the filter must be replaced.
Note: If too much grease is pumped into the reservoir, the surplus grease will exit the vent at the side of the lubrication pump. Any air that is introduced during the filling procedure will also escape via this route.
Note: Due to the slow capability of a hand held grease gun, the use of a grease gun is not recommended in order to fill the reservoir.
Periodic Checks
• Check the grease level in the reservoir. Refill the reservoir on time.
• Check that the signal lamp is functioning.
• Check that the duty cycle that is indicated on the signal lamp is correct for the operating conditions.
• Check the lubrication pump for damage and check the lubrication pump for leakage.
• Check the grease lines for damage and check the grease lines for leakage.
• Check the conditions of the grease points that are served by the system. Sufficient fresh grease should be present.
• Check the operation of the system. Perform a cycle test. Refer to System Operation, Testing and Adjusting, RENR6739 for more information.
• Clean the lubrication pump and clean the surroundings of the lubrication pump.
• Every 500 hours replace the filter or every 500 hours clean the filter.
Note: When you use high pressure water or high pressure air to clean the machine, do not spray directly onto the lubrication pump. Water or dirt may enter the lubrication pump through the dearating openings.
Note: The automatic lubrication system reduces the time and effort that is taken in order to grease the machine significantly. However, do not neglect grease points that are not served by the automatic lubrication system.
Grease Recommendations
Grease should not contain graphite or PTFE. Use the correct grease in the automatic lubrication system.
The use of a partially fluid grease that is above the maximum temperature that is indicated in Table 1 is not permitted. Use of a partially fluid grease that is above the maximum indicated temperature can lead to the following.
• Excessive component wear
• A reduction in the efficiency of the system

Brake Accumulator (Service) - Check
SMCS - 4263-535
Personal injury or death can result from improper accumulator charging.
Dry Nitrogen is the only gas approved for use in the accumulator. Charging the accumulator with oxygen will cause an explosion. This danger will not happen if nitrogen cylinders with standard CGA (Compressed Gas Association, Inc.) Number 580 connections are used.
When ordering nitrogen gas, be sure that the cylinders are equipped with CGA Number 580 connections. Do not use color codes or other methods of identification to tell the difference between nitrogen and oxygen cylinders
Never use an adapter to connect your nitrogen charging group to a valve outlet used on both nitrogen, oxygen, or other gas cylinders. BE SURE YOU USE DRY NITROGEN (99.8% purity).
Refer to Systems Operation, Testing and Adjusting, "Brake Accumulator (Service) - Test and Charge" for more information.
