Injury from Work Equipment
Do not enter or put your hand, arm or any other part of your body
between movable parts, such as between the work equipment
and cylinders, or between the machine and work equipment.
If the control levers are operated, the clearance between the
machine and the work equipment will change and this may lead
to serious damage or personal injury.
If going between movable parts is necessary, always position
and secure the work equipment so that it cannot move.
Fire Extinguisher and First Aid Kit
As a precaution if any injury or fire should occur, always do the
following.
• Be sure that fire extinguishers have been provided
and read the labels to ensure that you know now to
use them. It is recommended that an appropriately
sized (2.27 kg [5 lb] or larger) multipurpose "A/B/C"
fire extinguisher be mounted in the cab. Check and
service the fire extinguisher at regular intervals and
make sure that all work site crew members are
adequately trained in its use.
• Provide a first aid kit in the storage compartment and
keep another at the work site. Check the kit
periodically and make any additions if necessary.
• Know what to do in case of injury from fire.
• Keep emergency numbers for doctor, ambulance
service, hospital and fire department near your
telephone.
If the machine catches fire, it may lead to serious personal injury
or death. If a fire occurs during operation, escape from the
machine as follows;
• Turn the starter switch "OFF" and shut down engine.
• If there is time, use the fire extinguisher to extinguish
as much of the fire as possible.
• Use the handrails and steps to escape from the
machine.
The above is the basic method for escaping from the machine,
but changing the method may be necessary according to the
conditions, so carry out practice drills at the work site.

- 17. SP001667 Page 15 Wheel Loader Safety Fuel, Oil and Hydraulic Fluid Fire Hazards Fuel, oil and antifreeze will catch fire if it is brought close to a flame. Fuel is particularly flammable and can be hazardous. Always strictly observe the following. Add fuel, oil, antifreeze and hydraulic fluid to the machine only in a well ventilated area. The machine must be parked with controls, lights and switches turned "OFF." The engine must be "OFF" and any flames, glowing embers, auxiliary heating units or spark causing equipment must be doused, turned "OFF" and/ or kept well clear of the machine. Static electricity can produce dangerous sparks at the fuel filling nozzle. In very cold, dry weather or other conditions that could produce a static discharge, keep the tip of the fuel nozzle in constant contact with the neck of the fuel filling nozzle, to provide a ground. Keep fuel and other fluid reservoir caps tight and do not start the engine until caps have been secured. Precautions When Handling Fluids at High Temperature Immediately after operations are stopped, the coolant, engine oil, and hydraulic oil are at high temperature and the radiator and hydraulic tank are still under pressure. Attempting to remove the cap, drain the oil or coolant, or replace the filters may lead to serious burns. Always wait for the temperature to go down, and follow the specified procedures when carrying out these operations. To prevent hot coolant from spurting out, shut down engine, wait for the coolant to cool, then loosen the cap slowly to relieve the pressure. To prevent hot oil from spurting out, shut down engine, wait for the oil to cool, then loosen the cap slowly to relieve the pressure. ARO1050S Figure 4 HAOA050L Figure 5 HAOA060L Figure 6
