SAFETY HINTS 1. BEFORE OPERATING THE MACHINE Think-safety first. In special situation, wear protective clothing including a safety helmet, safety shoes, gloves, safety glasses and ear protection as required by the job condition. Almost every accident is caused by disre- garding the simple and fundamental safety hints.
Page 16
Check daily according to the operation manual.Repair the damaged parts and tighten the loos-ened bolts. 13031SH05 Check for leakage of engine oil, hydraulic oil, fuel and coolant. Keep machine clean, clean machine regularly. 13031SH06 Do not operate the machine if it requires repairs. Operate after complete repair.
Page 17
UNAUTHORIZED MODIFICATION Any modification made without authorization from Hyundai can create hazards. Before making a modification, consult your Hyundai distributor. Hyundai will not be respon- sible for any injury or damage caused by any unauthorized modification. PREPARE FOR EMERGENCY Only in case of emergency, use the installed hammer for breaking the windshield of the cab, and then exit carefully.
Page 18
Do not use attachments that are not authorized by Hyundai or your Hyundai distributor. Use of unauthorized attachments could create a safety problem and adversely affect the proper opera- tion and useful life of the machine.
Page 19
SAFETY FEATURES Be sure all guards and covers are in their prop- er position. Have guards and covers repaired if damaged. Use safety features such as safety lock and seat belts properly. Never remove any safety features. Always keep them in good operating condition. Improper use of safety features could result in serious bodily injury or death.
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. 13031SH09 Sound the horn to warn nearby personnel before operating the machine. Remove all the obstacles like frost on the window before operating the machine for the good visibility.
Page 21
Provide proper ventilation when operating engine in a closed area to avoid the danger of exhaust gases. 13031SH13 Check the locations of underground gas pipes or water line and secure the safety before operation. 13031SH14 The operating near the electrical lines is very dangerous.
Page 22
Watch out for obstacles. Be particularly careful to check the machine clearance during the swing. 13031SH17 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 23
The operation on a slope is dangerous. Avoid operating the machine on a slope of over 10 degree. 13031SH21 Operate the machine after making ground flat when operation is required on a slope. 13031SH22 The swing on the slope can be danger of rolling over.
Page 24
Avoid traveling in a cross direction on a slope as it can cause the danger of rolling over and sliding. 13031SH25 Traveling on a slope is dangerous. Be sure to operate slowly when traveling down a slope and maintain the bucket at a height of 20~30cm(1ft) above the ground so that it can be used as brake in an emergency.
Page 25
Before traveling the machine, sound the horn to warn nearby personnel. Operate forward and backward correctly with confirming the location of the travel motor. 13031SH29 Slow down when traveling through obstacles or uneven ground. 13031SH30 When working on soft ground, place mats or wood boards on the ground to prevent the machine sinking.
Page 26
Additional track frame step can be fitted for wider optional shoe. In this case please contact your Hyundai distributor. Do not hold any control levers when getting on or off the machine.
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 cluster then repair. 13031SH33 Park on a flat place and stop the engine for inspecting and repairing.
Page 28
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 29
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. RD21071SH41 The antislip protection should be replaced if they have become worn or have been printed over.
