• Be sure to stop the engine when you are out of the driver's seat to clean and inspect the machine body and machine itself, or to check and adjust various parts.
• Choose non-hazardous flat, firm ground for inspection.

• When performing maintenance on the equipment, hang the DO NOT OPERATE sign where it will be obvious from and around the driver's seat.
• When performing maintenance or repairs, always lower attachments to the ground, stop the engine and secure the tracks with blocks.
• When performing maintenance on the equipment, always disconnect the negative battery cable.
• Before using tools, make sure you understand how to use them correctly and use tools in good condition and of the right size for the job.

Be Ready for an Emergency

• Keep a first-aid kit and fire extinguisher close at hand so you can use it when needed.
• Keep emergency contact information for doctors, hospitals and ERs handy.

• Wear clothes appropriate for working on equipment. Do not wear loose-fitting clothes as they may catch on the machine controls.
• When working on the equipment, use all safety gear, such as a helmet, safety glasses and shoes, that are required by law or regulation.
• Never perform maintenance while drowsy or under the influence of alcohol or drugs.

PRECAUTIONS WHEN WORKING

• Stop the machine on a hard and level location and make sure the area around the machine is free of obstacles and hazardous materials. When parking the machine indoors, select a spot that can be properly ventilated.
• When performing work such as with a hammer, fragments may go flying, so make sure only authorized persons are around the machine. Before servicing the machine, clean it off so there is no mud, debris, oil or the like sticking to it.

• Before getting on/off of the machine, clean off around the steps so there is no mud on them. Always give yourself 3-point support when getting on/off the machine.

• 3-point support means using both legs and one hand or both hands and one leg as you climb up/down.

(1)Safety Stand

• When you need to access the underside of the machine for maintenance purposes, but sure to support the machine with a safety stand. Getting under the machine while supporting the machine by machine's own hydraulic cylinder or using a hydraulic jack can be extremely dangerous in the event of a hydraulic fluid leakage or similar mishap.

(1) Lift Arm Stopper

(2) Arm Cylinder Rod

(A) FIT

• Make sure the lift arm stopper is properly engaged before performing any work beneath raised lift arms. Never attempt to do any work or move under the lift arms when they are not properly supported.
• Keep in mind that the lift arms may fall whenever hydraulic lines are disconnected, loosened, or removed. Any malfunction or failure in the hydraulics can also cause lift arms to drop.
• Always perform the necessary repairs or service whenever the lift arm stopper becomes damaged or malfunctioned, or part are missing. Damaged or malfunction the lift arm stopper may cause the lift arms to fall causing serious injury or death.

• Do not raise or lower the cabin while the engine is running as it may move, cause the machine to become unstable, resulting in serious injury or death. Always lower the working parts of the machine to the ground and stop the engine before attempting to raise or lower the cabin.

Starting the Machine Safely

• Before starting the engine, always sit in the driver's seat and make sure the area is safe and clear.
• As it is dangerous, never start the engine from anywhere but the driver's seat.
• Always check and make sure control lever(s) are not engaged before starting the engine.
• Never start the engine by hot-wiring the starter circuit. This is not only dangerous, but may damage the machine.
• Whenever it is necessary to open the engine covers or hood in order to service the machine, always prop them open.
• If it is absolutely necessary to run the engine while working on the machine, make sure you are clear of all rotating or moving parts. Also take care not to leave anything, such as tools or rags, near any moving parts.

• The engine, muffler, radiator, hydraulic line, etc., have parts that remain very hot even after the engine has been stopped. Be sure to avoid these parts, as touching them can result in burns. Radiator coolant, hydraulic fluid and oil also remain hot. Therefore, do not attempt to remove caps and plugs, etc., before these fluids have sufficiently cooled.
• Make sure the coolant temperature has dropped sufficiently before opening the radiator cap. Also, since the inside of the radiator is pressurized, when removing the cap, first loosen it to release the pressure before removing the cap completely.

• The pressure in the hydraulic circuit stays at pressure even after the engine stops. Before removing parts, such as hydraulic devices from the machine, first release the pressure. Please note that when releasing residual pressure, the machine itself and/or implements may move without warning, so be very careful when releasing the pressure.
• Oil gushing out under pressure is extremely dangerous as it may pierce your skin or your eyes. Similarly, oil leaking out of pinholes is not visible. So when checking for oil leaks, always wear safety glasses and gloves and use a piece of cardboard or a wood block to shield yourself from oil.

No Smoking or Open Flames while Fueling

• Fuel is extremely flammable and dangerous. Never smoke near fuel. If fuel is spilled on the machine, its engine, or electrical parts, it may cause a fire. If fuel is spilled, wipe it all up immediately.
• Never smoke while filling the machine with fuel. And always tighten the fuel cap securely and wipe up any spilled fuel.

• Always wear safety glasses and gloves when handling the battery.
• The gas generated by the battery is flammable. Never weld or use tools like a grinder near the battery. And never smoke near it.
• When disconnecting the battery, always disconnect the negative cable first. When connecting the battery, always connect the positive cable first.

Dispose of Waste Fluids Properly

• Never dispose of waste fluids on the ground, in the gutter, a river, pond or lake. Always dispose of hazardous substances like waste oil, coolant and electrolytic fluid in accordance with the relevant environmental protection regulations.
• Keep the safety plates clean so they can be read. If a safety plate is damaged and comes off or becomes illegible, put a plate with the same warnings back in its place.
