INTRODUCTION

SAFETY PRECAUTIONS

A machine's weight and the vibration it creates can cause the edge of a high wall to collapse. Keep your machine back from the edges of banks and excavations. Operating in rough virgin terrain with such hazards as trees, logs, large rocks and brush is called pioneering. Be sure you know the operating techniques required. Danger from falling branches and upturning roots is acute in pioneering. When pushing over trees, the machine must be equipped with proper overhead guards. Never allow the machine to climb up the root structure, especially when the tree is being felled. Use extreme care when pushing over any tree with dead branches. If engine has a tendency to stall for any reason under load or at idle, report this condition immediately. Do not operate the machine until the condition has been corrected. Periodically check the engine exhaust system for leaks. Exhaust gases are dangerous to the operator. Use common sense, care and good judgement to avoid accidents. Operate at speeds slow enough to insure complete control of the machine. Travel slowly in congested areas or on rough ground, slopes or near drop offs or on snow, ice or slippery surfaces. Maintain a safe distance between your machine and other vehicles according to the condition of the road and load. Keep the machine as close to the side of the road as is possible to provide for oncoming or passing vehicles. Observe instruments and warning lights frequently. Report any defects or unusual noises in machine during operation. Be alert to the location of other personnel. Do not operate if exposed personnel enter the immediate work area. Warn all ground persons to leave the area of the machine. Do not operate the machine in a condition of extreme fatigue or illness. Be especially careful at the end of a work shift. Keep your work area as smooth as possible and free of obstructions. When pulling or towing with a chain or cable, take up the slack carefully. A sudden jerk could snap the chain or cable causing it to whip dangerously. Do not pull or tow unless the operator compartment is guarded for a whipping chain or cable. Clear personnel from the area. Be sure chains or cables and their anchor points are strong enough to handle the expected load. Inspect carefully for flaws before using. Always wear gloves when handling chains or cables. Avoid kinking the chain or cable. Do not pull with a kinked chain or cable as the high stress could cause a failure in the kinked area. Use only designated towing or pulling attachment points. Be sure pins are attached securely before pulling. Stand clear of chains or cables under load. Where noise exposure exceeds 90 dBA for 8 hours, wear authorized ear protective equipment. Keep engine exhaust system and exhaust manifold clear of combustible material for your personal protection. Know the locations of underground cables, water mains, gas lines, etc. A ruptured gas line or cut electrical cable could result in personal injury or death. Never use the mounted equipment as a brake except in an emergency. Do not adjust the seat position while the machine is in motion. A loss of control may result. Completely stop the machine, apply and lock the parking brake and then adjust the seat. During operation always carry ripper in full raised position when not in use and lower to ground when parked. Keep head, body, feet, hands and fingers away from the blade and ripper when they are in a raised position. Carry the blade low for maximum stability and visibility. Never leave the machine unattended while the engine is operating. When parking the machine, be sure all mounted equipment is lowered completely to minimize damage or injury possibilities. Do not allow the hydraulic system to support the mounted equipment when leaving the machine unattended. When leaving the machine unattended for any length of time, make sure the transmission/steering lever is positioned and locked in neutral (N), the blade and rear mounted equipment are completely lowered, the engine is stopped and the electrical master switch is locked in the OFF position. Never hold the hydraulic controls in their extreme position after the equipment has reached its maximum travel. This could cause overheating of the hydraulic system. MAINTENANCE Lower the blade to the ground or hold up with blocking, safety bar or hoist. Lower all equipment to the ground. Shift all controls to NEUTRAL position. Lock the transmission selector in NEUTRAL to neutralize the transmission and apply
