h .. Become thoroughly familiar with all fractor and attachment controls before operating. h CAUTION: If necessary to move tractor on a trailer, always back up .. onto the trader and drive off of trailer. CAUTION: Hydraulic systems are highly pressurized. Escaping hy- draulic oil. even an invisible pinhole leak, can penetrate body tissues causing serious injury. Use a piece of wood or cardboard when looking for leaks never use the hands or other parts of the body. A Relieve hydraulic pressure before disconnecting circuits. When reo assembling, make absolutely certain that all connections are tight. If injured by hydraulic oil escaping under pressure, see a doctor immediately. Serious complications may arise if medical attention is not given at once. A A A CAUTION: When adjusting steering wheel free play make certain that some free play remains between the sector gear and pinion gear, since a tight fit, with no clearance between the two gears may cause hinding and tooth failure. CAUTION: When removing a battery, always disconnect the H negative ground cable fint. When installing the hattery, always connect the (.) negative ground cable last. CAUTION- Storage areas for battenes must be weli ventilated to prevent accumulation of hydrogen gas from newly recharged battenes. VI
A A A DANGER Battenes produce explosIVe charges Keep sparks. flame and cigarettes away. Ventilate when chargmg or usmg m enclosed space. Always shield eyes when workmg near battenes. CAUTION: Never wear rmgs or meta! watch bands when workmg with the tractor electncal system or battery as you may ground a live CircuIt. CAUTION: When working around storage batteries, remember that all of the exposed metal parts are "live", Never lay a metal object across the terminals as a spark or short circuit may result. Sparks, lighted matches and exposed flames must be kept away from the battery due to the presence of explosive gas in the battery. The liquid in the batteries is acid. Use care not to spill it on hands or clothing. A WARNING: To jump start this machine, connect POSitive jumper cable to battery terminal on starter solenoid and connect negative jumper cable to good engine ground. Start engine only when seated in operator's seat. Stop engine before leaving machine. Disconnect jumper cables. Any other method could result in uncontrolled machine movement. IMPORTANT: Always install new decals whenever the old decals are destroyed, lost, painted over or illegible. When individual parts are replaced that have decals attached, be sure to install a new decal with the new part. Replacement decals are available from your Case dealer. VI!
HILLSIDE (SLOPE) OPERATION A WARNING: slopes can he dangerolls. Avoid improper operatmn! Read and fol" low the instructions given in the section titled "Hillside Operation" in this manual before operating your tractor. Improper operation of yOllr tractor on hillsides and Avoid operating tractor on hillsides and slopes. To minimize the possibility of acei dents while operating on hills and/or rough terrain, obey a combination of rules, prac- tices and good common sense. These include: 1. Reading, understanding, and obeying all written safety messages appearing on decals on the machine and in operator's manuals. 2. Learning from your operator's manual and carefully from EXPERIE,NCE how to op- erate your tractor correctly. Know your tractor's limitations, 3. Knowing the terrain on which you are operating your tractor. There are terrain condi tions on which 'lour tractor cannot be operated! 4. Learning to expect changes in operating conditions. Adding or removing attachments or weight to your tractor will make your tractor perform differently. Rain. snow, loose gravel, wet grass, etc., change the tractive conditions of the terrain requiring changes in your operating technique or not to operate on that terrain. The following paragraphs will cover these practices one at a time. Read and study them. The examples provided are not all inclusive but will give you a nrm understanding of the requirements for avoiding accidents while operating your tractor. Case Lawn and Garden Tractors are designed and built to comply with the Voluntary Standard ANSI B71.1 - 1980 (American National Standards Institute). THE OPERATOR IS THE SOLE JUDGE AS TO THE DEGREE OF SLOPE ON WHICH THIS TRACTOR CAN BE SAFELY OPERATED. IF IN DOUBT THAT THIS TRACTOR CAN BE SAFELY OPERATED ON A PARTICULAR SLOPE, DO NOT OP ERATE ON THAT SLOPE! COMMON SENSE MUST PREVAIL. VIII
Understand,.2b!!Y: ~ , Safety messages are found on the tractor and in the operator's manuals. These must be understood by the tractor o ~ to be of value. Be sure that these messages a r e ~ i e d before starting andlor operating the tractor by an operator not familar with this particu- lar tractor. Learn to ORerate: Learn your tractors controls from decals on the tractor and from instructions in the operator's manual. Practice how to properly manipulate these controls. Practice must be done in a flat area, clear of obstacles and bystanders. Learn your tractors operating characteristics and limitations. These include: a. amount of engine power available b. engine governor response c. tractive abiHty d. steering characteristics e. braking characteristics f. movement of travel lever g. forward and reverse ground speeds h. speed of attachment lift i. and others Attempting any operation which approaches or exceeds the tractor's limitation is risk ing an accident. Know the Terrain: Know the terrain on which you are working, Find hidden obstacles by walking through and inspecting the area prior to operating your tractor on it, Mark obstacles, such as, rocks, ruts or holes with a 6 ft long pole and red flag and lli!Y well clear of th0se Qb tacles when operating. Operate your tractor at a ground speed slow enough to insure complete control at aU times, Place the transmiSSIOn in low range and regulate the travel control lever slowly and smoothly to maintain this safe Always drive in a forward direction when proceeding downhill. Never drive up a hill. If necessary, back up a hi!! to the desired position, Always back up loading ramps and tilt bed trailers. If necessary to turn while on a hill, always turn downward. IX
Your judgement, based on operating experience is the final word in deciding if you should negotiate any given hill Of slope. If you are in doubt about safety . STAY OFF THE SLOPE. Under no circumstances should an inexperienced operator attempt to use your trac- tor 011 slopes or hillsides. You may encounter some terrain 011 which your tractor cannot be operated even if a different piece of equipment has operated there in the past. learn to Compensate for C h a n g 2 ! l ! : L Q ~ e r a t i n g Conditions: M.!;il,Qg or removing attachments or ballast (such as wheel weights or fluid) change the weight and weight distribution of your tractor and, therefore, change your tractors opera- ting characteristics. Be alert to these changes. Practice, operating the tractor after each change has been made. Adding an attachment (weight) to the rear of the tractor reduces the weight on the front axle. Adding an attachment (weight) to the front of the tractor reduces weight on the rear of the tractor. You must add counterweight to the from if a rear mounted at. tachment is installed. You must add counterweight to the rear if a front mounted at tachment is installed. Tractive conditions will vary with weather and terrain and equipment. Areas wet with dew, rain or snow will be more slippery than when dry. Areas covered with loose gravel are more slippery than firm dry ground. Greater stopping distances are required in these slippery areas. Spinning rear wheels tend to move the tractor sideways. The addition of tire chains wi!! provide more traction to the rear wheels in the forward-reverse direction but less sta- bility in the sideways direction. Chains will cause more abrupt starting and stopping. The final word in safe tractor operation rests on your judgement. If in doubt of your safety - STAY OFF THE SLOPE. x
