SAFETY FIRST

KiSC issued 03, 2007 A

SAFETY INSTRUCTIONS

This symbol, the industry’s “Safety Alert Symbol”, is used throughout this manual and on labels on

the machine itself to warn of the possibility of personal injury. Read these instructions carefully.

It is essential that you read the instructions and safety regulations before you attempt to repair or use

this unit.

DANGER : Indicates an imminently hazardous situation which, if not avoided, will result in

death or serious injury.

WARNING : Indicates a potentially hazardous situation which, if not avoided, could result in

death or serious injury.

CAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in

minor or moderate injury.

■ IMPORTANT : Indicates that equipment or property damage could result if instructions are not

followed.

■ NOTE : Gives helpful information.

BEFORE SERVICING AND REPAIRING

• Read all instructions and safety instructions in this manual and on your machine safety decals.

• Clean the work area and machine.

• Park the machine on a firm and level ground, and set the parking brake.

• Lower the implement to the ground.

• Stop the engine, and remove the key.

• Disconnect the battery negative cable.

• Hang a “DO NOT OPERATE” tag in operator station.

SAFETY INSTRUCTIONS

SAFETY STARTING

• Do not start the engine by shorting across starter terminals or bypassing the safety start switch.

• Do not alter or remove any part of machine safety system.

• Before starting the engine, make sure that all shift levers are in neutral positions or in disengaged positions.

• Never start the engine while standing on ground. Start the engine only from operator’s seat.

SAFETY WORKING

• Do not work on the machine while under the influence of alcohol, medication , or other substances or while fatigued.

• Wear close fitting clothing and safety equipment appropriate to the job.

• Use tools appropriate to the work. Makeshift tools, parts, and procedures are not recommended.

• When servicing is performed together by two or more persons, take care to perform all work safely.

• Do not work under the machine that is supported solely by a jack. Always support the machine by safety stands.

• Do not touch the rotating or hot parts while the engine is running.

• Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise, hot water will spout out from radiator. Only remove radiator cap when cool enough to touch with bare hands. Slowly loosen the cap to first stop to relieve pressure before removing completely.

• Escaping fluid (fuel or hydraulic oil) un der pressure can penetrate the skin causing serious injury. Relieve pressure before disconnecting hydraulic or fuel lines. Tighten all connections before applying pressure.

AVOID FIRES

• Fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in your working area.

• To avoid sparks from an accidental short circuit, always disconnect the battery negative cable first and connect it last.

• Battery gas can explode. Keep sparks and open flame away from the top of b attery, especially when charging the battery.

• Make sure that no fuel has been spilled on the engine.

SAFETY INSTRUCTIONS

VENTILATE WORK AREA

• If the engine must be running to do some work, make sure the area is well ventilated . Neve r run the eng ine in a closed area. The exhaust gas contains poisonous carbon monoxide.

PREVENT ACID BURNS

• Sulfuric acid in batte ry electrolyte is poisonou s. It is strong enough to burn skin, clothing and cause blindness if splashed into eyes. Keep electrolyte away from eyes, hands and clothing. If you spill electrolyte on yourself, flush with water, and get medical attention immediately.

DISPOSE OF FLUIDS PROPERLY

• Do not pour fluids into the ground, down a drain, or into a stream, pond, or lake. Observe relevant environmental prot ectio n regulati ons whe n disp osing of oil, fuel, coolant, electrolyte and other harmful waste.

PREPARE FOR EMERGENCIES

• Keep a first aid kit and fire extingui sher handy at all times.

• Keep emergency numbers for doctors, ambulance service, hospital and fire department near your telephone.

2. GENERAL PRECAUTIONS

• During disa ssembly, ca refully ar range removed parts in a cle an area to prevent confusion later. Screws, bolts and nuts should be installed in their original position to prevent reassembly errors.

• When special tools are requi red, use KUBOT A genuine speci al tools. Special tools which are not frequently used should be made according to the drawings provided.

• Before disassembling or servicing electrical wires, always disconnect the ground cable from the battery first.

• Remove oil and dirt from parts before measuring.

• Use only KUBOTA genuine parts for parts replacement to maintain machine performance and to assure safety.

• Gaskets and O-rings must be replaced during reassembly. Apply grease to new O-rings or oil seals before assembling. See the figure left side.

• When reassem bling external snap rings or inte rnal snap rings, they must be positioned so that sharp edge faces against the direction from which a force is applied. See the figure left side.

• When insert ing spring pins, their splits must face the direction from which a force is applied. See the figure left side.

• To prevent dam age to the hydraulic s ystem, use only sp ecified fluid or equivalent.

3. HANDLING PRECAUTIONS FOR ELECTRICAL PARTS AND WIRING

To ensure safety and prevent damage to the machine and surrounding equipm ent, heed the following pr ecautions in handling electrical parts and wiring.

• Check electrical wiring for damage and loosened connection every year. To this end, educate the customer to do his or her own check and at the s ame time recommend the dealer to perform periodic check for a fee.

• Do not attempt to modify or remodel any electrical parts and wiring.

• When removing th e ba tter y cab le s, dis co nn ect t he n egat ive cable first. When in stalling the b attery cables, c onnect the positive cable first.

(1) Negative Terminal (2) Positive Terminal

[2] BATTERY

[3] FUSE

G GENERAL

• Take care not to confuse positive and negative terminal posts.

• When removing b attery cables, disconnect negative cable first. When installing battery cables, check for polarity and connect positive cable first.

• Do not install a ny battery with capacity other than is specified (Ah).

• After connecting cables to battery terminal posts, apply high temperature grease to them a nd sec urely in stall t erminal covers on them.

• Do not allow dirt and dust to collect on battery.

CAUTION

• Take care not to let battery liquid spill on your skin and clothes. If contaminated, wash it off with water immediately.

• Before recharging the battery, remove it from the machine.

• Before recharging, remove cell caps.

• Do recharging in a well- ventilated place where there is no open flame nearby, as hydrogen gas and oxygen are formed.

W10118160

[4] CONNECTOR

• Use fuses with specified capacity. Neither too large or small capacity fuse is acceptable.

• Never use steel or copper wire in place of fuse.

• Do not install working light, radio set, etc. on machine which is not provided with reserve power supply.

• Do not install accessories if fuse capacity of reserve power supply is exceeded.
