Avoid Static Refueling

Electricity Risk When

RG21992-UN: Static Discharge (Fuel Nozzle)

The removal of sulfur and other compounds in Ultra-Low Sulfur Diesel (ULSD) fuel decreases its conductivity and increases its ability to store a static charge.

Refineries may have treated the fuel with a static dissipating additive. However, there are many factors that can reduce the effectiveness of the additive over time.

Static charges can build up in ULSD fuel while it is flowing through fuel delivery systems. Static electricity discharge when combustiblevaporsarepresentcouldresultinafireorexplosion.

Therefore, it is important to ensure that the entire system used to refuel your machine (fuel supply tank, transfer pump, transfer hose, nozzle, and others) is properly grounded and bonded.

Use and Maintain Seat Belt

T133716-19: Use and Maintain Seat Belt

Use seat belt when operating machine. Remember to fasten seat belt when loading and unloading from trucks and during other uses.

Examine seat belt frequently. Be sure that webbing is not cut or torn. Replace seat belt immediately if any part is damaged or does not function properly.

The complete seat belt assembly should be replaced every three years, regardless of appearance.

Be careful not to accidentally actuate controls when coworkers are present.

NOTE: Transmission control lever (TCL) needs to be in neutral for park brake to be released. The TCL does not need to be in neutral for park brake to be applied.

Lower all equipment to the ground during work interruptions.

Place transmission control lever in neutral, press park brake switch (1)to engage parkbrake, andstop engine before allowing anyone to approach the machine.

Follow these same precautions before standing up, leaving the operator′s seat, or exiting the machine.

Avoid Work Site Hazards

Avoid contact with gas lines, buried cables and water lines.

Call utility line location services to identify all underground utilities before starting work.

Prepare work site properly. Avoid operating near structures or objects that could fall onto the machine. Clear away debris that could move unexpectedly if run over.

Use barricades or a signal person to keep vehicles and pedestrians away. Use a signal person if moving machine in congested areas or where visibility is restricted. Always keep signal person in view. Coordinate hand signals before starting machine.

Operate only on solid footingwith strength sufficient to support machine. Be especially alert working near embankments or excavations.

Avoid working under over-hanging embankments or stockpilesthat could collapse under or on machine.

Reduce machine speedwhen operating with tool on or near ground when obstacles may be hidden (e.g., during snow removal or clearing mud, dirt, etc.). At high speeds hitting obstacles (rocks, uneven concrete or manholes) can cause a sudden stop. Always wear your seat belt.

Before moving machine, be sure that all persons are clear of machine path.Turn around and look directly for best visibility.

Use mirrors to assist in checking all around machine. Keep windows and mirrors clean, adjusted, and in good repair.

Be certain reverse warning alarm is working properly.

Use a signal person when backing if view is obstructed or when in close quarters. Keep signal person in view at all times.

Use prearranged hand signals to communicate.

Do not rely on the rear camera and radar object detection systems, if equipped, to determine if personnel are behind the machine. The system has limitations due to maintenance practices, environmental conditions, and operating range.

Avoid Machine Tip-Over

TX1054283-UN: Ensure Solid Footing

Use seat belt at all times.

Do not jump if the machine tips. You will be unlikely to jump clear and the machine may crush you.

Load and unload from trucks or trailers carefully.

Be sure truck is wide enough and on a firm level surface. Use loading ramps and attach them properly to truck bed.

Be careful on slopes.

Drive directly up or down steep slopes whenever possible. Minimize articulation for best machine stability when driving and turning across slopes. Use extra care on wet, soft or frozen surfaces because machine may slide more easily with these conditions.

Ensure solid footing.

Do not operate close to banks or open excavations that may cave in and cause machine to tip or fall.

Transmission Control Unit (TCU) Diagnostic Trouble Codes

000070.03— Park Brake Pressure Switch Circuit Fault Park brake pressure switch (B21) is open while starting, indicating park brake is not on while starting in park.

NOTE: Transmission will default to neutral. Transmission must be shifted to neutral to recover from code. To recover and restore normal operation, the cause of the malfunction must first be determined and corrected.

Transmission Control Unit (TCU) Diagnostic Trouble Codes

000070.04— Park Brake Pressure Switch Circuit Fault Park brake pressure switch (B21) is open while starting, indicating park brake is not on while starting in park.

NOTE:

Transmission will default to neutral. Transmission must be shifted to neutral to recover from code. To recover and res normal operation, the cause of the malfunction must first be determined and corrected.
