2.6 PRECAUTIONS FOR INSPECTION AND MAINTENANCE
2.6.21 PERIODIC INSPECTION OF SAFETY CRITICAL PARTS
2
• To ensure the safety and long service life of the lift truck, be sure to perform lubrication, inspection and maintenance regularly. Especially the safety critical parts, must be replaced regularly. • Quality of these parts may change over time or deteriorate, wear or fatigue as they are repeatedly used, leading serious bodily injuries and damages. Furthermore, the remain ing service life of such parts is usually hard to determine for operators or during visual inspection. • For details of safety critical parts, see "4.15 PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS (PAGE 454)". • Replace the safety critical parts with a new one periodically even if no anomaly is found. • Replace the safety critical parts immediately when any abnormality is found, even if the replacement interval is not up yet. REMARK
• This Operation and Maintenance Manual does not describe the details on how to inspect or replace the safety critical parts. • Inspection and replacement of the safety critical parts, and refilling of greases must be done by KOMATSU FORKLIFT distributor.

2.7.1 CAUTION WHEN HOISTING THE LIFT TRUCK
2
• Never lift up by the overhead guard. • Before lifting-up, Check that the mounting bolts of mast and counterbalance-weight are tightened to the specified torque. Tightening torque for the counterbalance-weight mount bolts : 980 - 1,373Nm {100 - 140kgfm} Tightening torque for the mast lower mount bolts : 824 - 1,030Nm {84 - 105kgfm} • To hoist the lift truck, hook on the holes on the top of the outer mast for the front, and the hole on the top of the counterbalanceweight for the rear. • Do not go under the lifted truck. • Use undamaged wire having sufficient strength. For the hoisting of lift truck, see "4.12 HOISTING LIFT TRUCK (PAGE 4-47)".
2.7.2 PRECAUTIONS FOR LOADING AND UNLOADING THE LIFT TRUCK Loading and unloading a lift truck to and from a trailer always involve a hazard of the lift truck tipping over or falling off by handling error. Follow the instructions below: • Stop the trailer on level, flat road. Always apply parking brake. Apply blocks to the tyres. • Use ramps or dock plate of appropriate length, width and strength. Secure it tightly to prevent it from being dislocated or disengaged. • Take a right posture on the seat while operating. • If you operate the lift truck in such a posture that your weight is not properly applied to the seat, like standing up or leaning forward or sideways, travel interlock activates to cut off the transmission of engine power. Then the lift truck may slither down even if the accelerator pedal is stepped on or an uphill. Operate the lift truck assisted by a signal person if necessary so that you don't have to stand up or lean forward or sideways to watch. For more details on the function of travel interlocking, see "TRAVEL INTERLOCK (ENGINE POWER CUTOFF) (OPTION) (PAGE 3-30)". • When using the ramps, set them in gentle gradient, align the center of both the trailer and the lift truck and lock securely to prevent misalignment. • Do not change the course of the lift truck while on the ramps. If course change is needed, move off the ramps once and make another uphill travel on them in right direction.

2.8 STRUCTURE AND STABILITY OF THE LIFT TRUCK (TO PREVENT LIFT TRUCK FROM TIPPING)
2
To operate the lift truck safely, it is important to understand the structure and stability of the lift truck.
2.8.1 LONGITUDINAL STABILITY
2
• The front wheels of the lift truck act as a fulcrum, and the load weight and the weight on the rear wheels are kept in balance to prevent the lift truck from falling forward. • When an overbalanced load weight is applied, the rear wheels will be raised off the ground. It is very dangerous and poses a high risk of serious accident like tipping over.
Load
Load weight Fulcrum
2.8.2 CENTER OF GRAVITY OF A LOAD
Weight on the rear wheels

2.8 STRUCTURE AND STABILITY OF THE LIFT TRUCK (TO PREVENT LIFT TRUCK FROM TIPPING)
SAFETY
2.8.3 COMBINED CENTER OF GRAVITY AND STABILITY ON THE LOADED LIFT TRUCK
2
COMBINED CENTER OF GRAVITY The center of gravity of the loaded lift truck shifts to a combined center of gravity of both the lift truck and the load. When the load is raised, its center of gravity will rise, hence the combined center of gravity will also rise.
Combined center of gravity at high lifting height
Center of gravity of load
Combined center of gravity at low lifting height Center of gravity of lift truck
COMBINED CENTER OF GRAVITY AND STABILITY The higher the position of the center of gravity, the worse the longitudinal and lateral stabilities become. In addition, swaying or shock encountered during traveling or load handling will have a larger impact on the stability of the lift truck. Stability of the lift truck also changes depending on the following factors. • Size, weight, shape of load (position of center of gravity etc.) • Lifting height • Tilting angle of mast • Inflation pressure of tyres • Acceleration, deceleration and turning speed when traveling and load handling • Road condition and gradient • Type of attachments Do not travel with the forks (load) raised. Do not make sharp turns or apply sudden brakes. Do not raise or tilt the forks ab ruptly. There are dangerous and poses a high risk of serious accident like tipping over.
2.8.4 ACTUAL CAPACITY • The horizontal distance from the position of the center of gravity of a load on the forks to the upright load backrest of the fork is called a load center. Actual capacity means the maximum weight of a load that can be loaded at a certain load center. • The load table is given in the name plate accessible from the operator's seat. The table shows the relationship between the actual capacity and load center. • When the load center shifts toward the fork tips, the load weight (mass) has to be decreased in the actual operation to maintain the balance.

2.8.5 SERIAL NO. AND LOAD TABLE
2
A serial No. plate for lift trucks of the US specifications differs from the one shown above in the shape. Since actual conditions will vary, be sure to check your capacity rating being adequate fo r the particular job before beginning. If you are unsure at the capacity, please contact your employer for assistance.
EXPLANATION OF LOAD TABLE • In the load table of the serial No. plate, actual capacity and maximum load (2) are shown in relation to load center (1). • Actual capacity and maximum load are determined according to each model on the condition of the specifications shown in area (3). • Before loading, make sure that the load center and the load are well within the range of capacity. • When the load is in a complex shape, pull the load so that the heaviest portion of the load comes to closer to the load backrest and the lateral center comes to the two forks center. • Should a load be loaded beyond the range of capacity, it would pose a big danger to the lift truck as the rear wheels (for steering) may lift off the ground, letting the operator lose control of steering, or the lift truck may tip over. Always keep the load within the range of capacity. • Work within the specification ranges given in the serial No. plate attached to the lift truck. Replace the broken or unreadable serial No. plate. Call your KOMATSU FORKLIFT distributor for a new serial No. plate.
EXAMPLE OF LOAD CENTER AND ACTUAL CAPACITY • The areas (1) and (2) in the example provide the following information: When the load center is 600 mm - - - Maximum capacity: 10,000 kg (*1) When the load center is 800mm - - - - - -Capacity: 8,700 kg When the load center is 1,200mm - - - - Capacity: 6,800 kg *1: Even when the load center is smaller than 600 mm, the maximum capacity is 10,000 kg. • The area (3) shows the main specifications of the model. Max. lifting height :3m Attachment : Not equipped Front wheel tread : 1,700 mm Mast rear tilting angle : 12 degrees Front wheel size, inflation pressure: 9.00-20-14PR ( I ), 735 kPa Rear wheel size, inflation pressure : 9.00-20-14PR ( I ), 735 kPa

When refilling greases according to " Start-up inspection " and/or " Checking after operation ", do so by understanding the following basic cautions for required greases.
OIL
CAUTION • When checking leakage from hydraulic piping or hose, do not touch it directly by hand. The pipe or hose may be pressurized and can be dangerous. • If your skin and/or eye are injured by high-pressure oil, wash the skin/eye with fresh water and immediately see a physician. • For other than leakage that can be checked visually by the appearance, call your KOMATSU FORKLIFT distributor for inspection and repair service. • Since engine oil, hydraulic oil, TORQFLOW transmission oil, gear oil, etc. are used under severe conditions (at high temperature and high pressure), they deteriorate as the operation time passes. Therefore oil must be changed periodically. For the standard oil change intervals, see "OIL AND GREASING CHART (PAGE 4-24)" and "LUBRICANT LIST (PAGE 4-25)". • Always replace oil at the specified period even if not deteriorated. • Always use Genuine Engine oil. At shipment from a plant, the lift truck is applied with those listed in the "LUBRICANT LIST (PAGE 4-25)". • Never mix oils of different grade (class) or brand. • A lift truck should be maintained so that contaminants (water, metal chips, dust, etc.) do not enter the lift truck system. Most lift truck malfunctions are caused by entry of impurities such as dirt, dust, water, etc. Take special care to avoid entry of impurities during storage and lubrication, etc. • Add specified volume of oil. Insufficient or excessive amounts of oil may both cause problems. • If the hydraulic oil has become murky, there is a possibility that either air or water entered into the circuit. If no corrective measures were taken, it may damage the lift truck. In such a case, call your KOMATSU FORKLIFT distributor for their service. • When replacing oil, replace the relevant filters at the same time. For oil and filter changes, contact your KOMATSU FORKLIFT distributor for service.

INSPECTION AND MAINTENANCE
4.4 SIMPLE MAINTENANCE
FUEL
CAUTION Always use diesel oil for the fuel. To ensure good fuel consumption characteristics and exhaust gas characteristics, the engine mounted on this machine uses an electronically controlled high-pressure fuel injection device. This device requires high precision parts and lubrication, so if low viscosity fuel with low lubricating ability is used, the durability may drop markedly.
• At the end of the day's work, fill the fuel tank to full. Reducing the air inside the fuel tank helps reduce mixture in the fuel of condensed moisture from the air. • Since the fuel pump is a precision machine, it may fail to operate if fuel containing moisture and/or impurities is used. Take special care to avoid entry of moisture and impurities during storage and lubrication. • Always use fuel of appropriate grade from among those listed in the "LUBRICANT LIST (PAGE 4-25)". • When a diesel engine runs out of fuel or has its filters replaced, the fuel circuit has to be purged.
COOLING WATER (COOLANT AND DILUTED WATER)
CAUTION • After the engine stops, the coolant temperature is very high, and high pressure is accumulated inside the radiator. Do not remove the radiator cap under these conditions or it may cause burns. After the coolant temperature has gone down, turn the cap slowly to release the pressure before removing it. • Undiluted Supercoolant is flammable. So keep i t away from open flame. • Dilute the coolant according to the ambient temperature before applying to the radiator. Use distilled or soft water for dilution. Hard water contains high mineral contents (calcium and magnesium). These contents are deposited inside the radiator as water stain and scale, causing an overheat of engine. They are difficult to remove. For the radiator, it is recommended to use diluted water having total hardness of 100 ppm (mg/ l) or under. • This lift truck is filled with Genuine Supercoolant (FAF-NAC). This Supercoolant has other important function as the corrosion inhibitor of the cooling system than antifreeze function. Continue to use this Supercoolant in an area where antifreeze is not required. Using other brand of coolant may cause critical failure to the cooling system including the engine. • Genuine Supercoolant is good for continual use for two years or 4,000 service hours. • Apply different mixing ratio for the Supercoolant according to the outside temperature. For the right mixing ratio, see "4.6 RUNNING IN COLD WEATHER (PAGE 4-39)". • Shortage of coolant causes engine overheating and corrosive defect of cooling circuit due to the mixing of the air.

4.4 SIMPLE MAINTENANCE
GREASE • Grease prevents the joints from seizure, rusting and noise emission. • Always use recommended grease and strictly follow the greasing intervals. For the type of grease, see the "LUBRICANT LIST (PAGE 4-25)". • Wipe clean old grease extracted after greasing. Wipe grease off with particular care from sections where attached sands and dirt promote the wear of the rotating units.
FILTERS • Filters are very important items which prevent impurities contained in the oil, fuel and hydraulic circuits from entering important machine components to cause failure. They require periodical replacement. Call your KOMATSU FORKLIFT distributor for service. • Never have your lift truck parts changed by other than. Never reuse filters (cartridge type) after washing. • Always use Genuine Filters. NOTICE • Special filter of high-efficiency filtration property is adopted for the Genuine Fuel filter cartridges. Always use Genuine Parts for replacement. • The common rail fuel injection system adopted for the machine is configured with components of higher accuracy compared with conventional injection pumps and nozzles. Using other fuel filter cartridges than Genuine Parts may cause mixing of foreign matters, leading to a failure of injection system. Never use substitute parts. • For inspection and maintenance of the fuel system, more care should be given for the mixing of foreign matters than before. Attached dirt, if any, must be fully washed off using fuel. • Some of commercial filters are inferior to the genuine product in performance. Using such fil ters may affect performance and durability of the fork truck. If genuine Komatsu Utility products are not used, quality assurance may not apply.

4.15 PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS
4
For your safety use of lift trucks, you are requested to always implement period ic replacement of parts listed in the Periodic Replacement of Safety Critical Parts below related particularly to the safety and fires. The material of these parts may change over time, or may easily wear or deteriorate. However, as it is difficult to judge the condition of the parts simply by periodic maintenance, they should always be replaced after a fixed time has passed, regardless of their condition. This is necessary to ensure that their full function is always maintained. However, if these parts show any abnormality before the replacement interval has passe d, they should be repaired or replaced immediately. If the hose clamps show any sign of deterioration such as deformation or cracking, replace them with the hoses at the same time. Note that the periodic replacement is not covered by warranty.
