Page 28: Fire Prevention And Explosion Prevention
FIRE PREVENTION AND EXPLOSION PREVENTION Regeneration The exhaust gas temperatures during regeneration will be elevated. Follow proper fire prevention instructions and use the disable regeneration function when appropriate. General All fuels, most lubricants, and some coolant mixtures are flammable. To minimize the risk of fire or explosion, the following actions are recommended.
Page 29 Store fuels and lubricants in properly marked containers away from unauthorized personnel. Store oily rags and flammable materials in protective containers. Do not smoke in areas that are used for storing flammable materials. 3001SH02 Use caution when you are fueling a machine. Do not smoke while you are fueling a machine.
Page 30 Fire on a machine can result in personal injury or death. Exposed battery cables that come into contact with a grounded connection can result in fires. Replace cables and related parts that show signs of wear or damage. Contact your Hyundai dealer. Wiring Check electrical wires daily.
Page 31 Do not operate a machine when a fire hazard exists. Repair any lines that are corroded, loose, or damaged. Leaks may provide fuel for fires. Consult your Hyundai dealer for repair or for replacement parts. Ether Ether (if equipped) is commonly used in cold weather applications.
Page 32 Fire Extinguisher As an additional safety measure, keep a fire extinguisher on the machine. Be familiar with the operation of the fire extinguisher. Inspect the fire extinguisher and service the fire extinguisher regularly. Follow the recommendations on the instruction plate. Consider installation of an aftermarket Fire Suppression System, if the application and working conditions warrant the installation.
Page 33 Do not weld the ROPS structure in order to install the fire extinguisher. Also, do not drill holes in the ROPS structure in order to mount the fire extinguisher on the ROPS. Consult your Hyundai dealer for the proper procedure for mounting the fire extinguisher. 1-11...

Page 38: During Operating The Machine
2. DURING OPERATING THE MACHINE Use the handle and footstep when getting on or off the machine. Do not jump on or off the machine. 17W31SH09 Sound the horn to warn nearby personnel before operating the machine. Remove all the obstacles like frost on the win- dow before operating the machine for the good visibility.
Page 39 Provide proper ventilation when operating engine in a closed area to avoid the danger of exhaust gases. 17W31SH13 Check the locations of underground gas pipes or water line and secure the safety before oper- ation. 17W31SH14 The operating near the electrical lines is very dangerous.
Page 40 Watch out for obstacles. Be particularly careful to check the machine clearance during the swing. 17W31SH17 When using the machine as breaker or working in a place where stones may fall down, cab roof guard and head guard should be provided for proper protection.
Page 41 Avoid traveling in a cross direction on a slope as it can cause the danger of rolling over and slid- ing. 17W31SH21 Traveling on a slope is dangerous. Be sure to operate slowly when traveling down a slope and maintain the bucket at a height of 20~30 cm (1 ft) above the ground so that it can be used as brake in an emergency.
Page 42 The operation on a slope is dangerous. Avoid operating the machine on a slope of over 10 degree. 17W31SH25 Operate the machine after making ground flat when operation is required on a slope. 17W31SH26 The swing on the slope can be danger of rolling over.
Page 43 Before traveling the machine, sound the horn to warn nearby personnel. Operate forward and backward correctly with confirming the location of the travel motor. 17W31SH29 Slow down when traveling through obstacles or uneven ground. 17W31SH30 When operating in water or when crossing shal- low, check the bed soil condition and depth and flow speed of water, then proceed taking care that water is not above axle center.
Page 44: Mounting And Dismounting
When mounting or dismounting, always face the machine and use the handrails, machine or foot steps. In this case please contact your Hyundai distributor. Do not hold any control levers when getting on or off the machine.
Page 45: During Maintenance
3. DURING MAINTENANCE Stop the engine immediately when the trouble of the machine is found. Inspect immediately the cause of trouble such as vibration, overheating and trouble in the clus- ter then repair. 17W31SH32 Park on a flat place and stop the engine for inspecting and repairing.
Page 46 There is the danger of fire in fuel and oil. Store in cool and dry area, away from any open flames. 13031SH37 Do not touch exhaust pipe, or may cause severe burn. 13031SH38 Do not open the engine hood and covers while the engine is running.
Page 47 Be careful that the front window may be promptly closed. Be sure to support stay, when the side door needs to be opened. Be careful that the open side door may closed by the external or natural force like strong wind. 13031SH41 The antislip protection should be replaced if they have become worn or have been printed...
Page 48: Parking
4. PARKING When leaving the machine after parking, lower the bucket to the ground completely and put the safety lever at parking position then remove the key. Lock the cab door. 17W31SH43 Park the machine in the flat and safe place. 17W31SH44 Hope you can work easily and safely observing safety rules.
