Before Operation

Before Operation Safety
General Safety
  • Never allow children or untrained people to operate the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.
  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.
  • Inspect the area where you will use the machine and remove all objects that could interfere with the operation of the machine.
  • Know and mark the locations of all utility lines.
  • Check that the operator's presence controls, safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.
  • Locate the pinch point areas marked on the machine and keep your hands and feet away from these areas.
  • Do not carry passengers on the machine.
  • Keep bystanders, especially children, out of the operating area. Ensure that the area is clear of bystanders before operating the machine. Shut off the machine if a bystander enters the area.
  • Park the machine on a level surface, engage the parking brake, and shut off the engine. Wait for all movement to stop and allow the machine to cool before adjusting, servicing, cleaning, or storing the machine.
Fuel Safety
Use extreme care in handling fuel. It is flammable and its vapors are explosive.
  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
  • Use only an approved container.
  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.
  • Do not add or drain fuel in an enclosed space.
  • Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or other appliance.
  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.
  • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle before filling.
  • Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle.
  • Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle-lock-open device.
  • Do not operate the machine without the entire exhaust system in place and working properly.
  • Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.
    • Avoid prolonged breathing of vapors.
    • Keep your face away from the nozzle and fuel tank or conditioner opening.
    • Keep fuel away from your eyes and skin.

Performing Daily Maintenance
Before starting the machine each day, perform the Each Use/Daily procedures listed in the Maintenance Schedule.

During Operation

During Operation Safety
General Safety
  • The owner/user can prevent and is responsible for accidents that may cause personal injury or property damage.
  • Do not exceed the rated operating capacity, as the machine may become unstable, which may result in loss of control.
  • Wear appropriate clothing including eye protection, long pants, substantial slip-resistant footwear, and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry.
  • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.
  • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.
  • Operate the machine only in good light, keeping away from holes and hidden hazards.
  • Ensure that all drives are in the Neutral position before starting the engine. Start the engine only from the operating position.
  • Keep your hands and feet away from moving parts. If possible, do not make adjustments with the engine running.
  • Never jerk the controls; use a steady motion.
  • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
  • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.
  • Operate the engine only in well-ventilated areas. Exhaust gasses contain carbon monoxide, which is lethal if inhaled.
  • Never leave a running machine unattended.
  • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.
  • Be aware of obstacles in close proximity to you. Failure to maintain adequate distance from trees, walls, and other barriers may result in injury as the machine backs up during operation if you are not attentive to the surroundings.
  • Check for overhead clearance (i.e., electrical wires, branches, and doorways) before driving under any objects and do not contact them.
  • Do not overload the hopper and always keep the load level when operating the machine.
  • Keep the hopper lowered and straight (if applicable) when moving, storing, loading, transporting, and cleaning the machine.
  • Do not modify the machine.
  • Use care and slow down when you are operating the machine on a slippery surface.
  • Always look down and behind you before moving the machine in reverse.
  • If you feel uneasy operating the machine because the terrain is rough, slippery, or unfamiliar, do not do it.
  • Distribute loads evenly to improve the stability and control of the machine.
  • Liquid loads shift, which can cause the machine to tip over.
Slope Safety
  • Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, do the following:
    • Review and understand the slope instructions in the manual and on the machine.
    • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Always use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.
  • Do not raise the hopper on a slope. Raising the hopper on a slope affects the stability of the machine. Keep the hopper in the lowered and straight position when on slopes.
  • When operating on a slope, fold the platform up and walk behind the machine until it is on flat ground.
  • Operate up and down slopes with the heavy end of the machine uphill. Weight distribution changes with a full hopper. A full hopper makes the front of the machine the heavy end, so walk behind the machine with the full hopper uphill.
  • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a wheel or track goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard.
  • Avoid starting, stopping, or turning the machine on a slope. Avoid making sudden changes in speed or direction; turn slowly and gradually.
  • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.
  • Do not operate the machine under any conditions where traction, steering, or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the wheels or tracks may result in sliding and a loss of braking and steering. The machine can slide even if the wheels or tracks are stopped.
  • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
  • If you lose control of the machine, step off and away from the direction of travel of the machine.

Cleaning

Removing Debris
Important  
Operating the engine with blocked screens, dirty or plugged cooling fins, and/or cooling shrouds removed, will result in engine damage from overheating.
 
  1. Park the machine on a level surface and shut off the engine. Allow the engine to cool.
  2. Unlatch and remove the cowl.
  3. Clean any debris from under the hopper.
  4. Wipe away debris from the air cleaner.
  5. Clean any debris buildup on the engine and in the transmission with a brush or blower.
    Important  
    It is preferable to blow dirt out rather than washing it out. If you use water, keep it away from electrical items and hydraulic valves.
    Do not use a high-pressure washer. High-pressure washing can damage the electrical system and hydraulic valves or deplete grease.
