SAFETY
The proper and safe lubrication and maintenance for these lift trucks, recommended by Mitsubishi Forklift Trucks, are outlined in the OPERATION & MAINTENANCE MANUAL.
Read and understand the OPERATION & MAINTENANCE MANUAL before performing any lubrication or maintenance on these trucks. Improper performance of lubrication or maintenance procedures is dangerous and could result in injury or death.
The serviceman or mechanic may be unfamiliar with many of the systems on this truck. This makes it important to use caution when performing service work. A knowledge of the system and/or components is important before the removal or disassembly of any component.
Do not operate these trucks unless you have read and understood the instructions in the OPERATION & MAINTENANCE MANUAL. Improper truck operation is dangerous and could result in injury or death.
(5) Use steps and grab handles (if applicable) when mounting or dismounting a truck. Clean any mud or debris from steps, walkways or work platforms before using. Always face truck when using steps, ladders and walkways. When it is not possible to use the designed access system, provide ladders, scaffolds, or work platforms to perform safe repair operations. (6) To avoid back injury, use a hoist when lifting components which weigh 23 kg or more. Make sure all chains, hooks, slings, etc., are in good condition and are of the correct capacity. Be sure hooks are positioned correctly. Lifting eyes are not to be side loaded during a lifting operation.
Because of the size of some of the truck components, the serviceman or mechanic should check the weights noted in this Manual. Use proper lifting procedures when removing any components.
(7) To avoid burns, be alert for hot parts on trucks which have just been stopped and hot fluids in lines, tubes and compartments.
Following is a list of basic precautions that should always be observed.
(8) Be careful when removing cover plates. Gradually back off the last two bolts or nuts located at opposite ends of the cover or device and pry cover loose to relieve any spring or other pressure, before removing the last two bolts or nuts completely.
(1) Read and understand all warning plates and decals on the truck before operating, lubricating or repairing the product. (2) Always wear protective glasses and protective shoes when working around trucks. In particular, wear protective glasses when pounding on any part of the truck or its attachments with a hammer or sledge. Use welders gloves, hood/goggles, apron and other protective clothing appropriate to the welding job being performed. Do not wear loose fitting or torn clothing. Remove all rings from fingers when working on machinery. (3) Do not work on any truck that is supported only by lift jacks or a hoist. Always use blocks or jack stands to support the truck before performing any disassembly. (4) Lower the forks or other implements to the ground before performing any work on the truck. If this cannot be done, make sure the forks or other implements are blocked correctly to prevent them from dropping unexpectedly.
2
(9) Be careful when removing filler caps, breathers and plugs on the truck. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure. The danger is even greater if the truck has just been stopped because fluids can be hot. (10)Always use tools that are in good condition and be sure you understand how to use them before performing any service work. (11)Reinstall all fasteners with same part number. Do not use a lesser quality fastener if replacements are necessary. (12)If possible, make all repairs with the truck parked on a level, hard surface. Block truck so it does not roll while working on or under truck.
(13)Before starting to work on truck, hang "Do not Operate" tag in the Operator's Compartment. (14)Repairs, which require welding, should be performed only with the benefit of the appropriate reference information and by personnel adequately trained and knowledgeable in welding procedures. Determine type of metal being welded and select correct welding procedure and electrodes, rods or wire to provide a weld metal strength equivalent at least to that of parent metal. (15)Do not damage wiring during removal operations. Reinstall the wiring so it is not damaged nor will it be damaged in operation by contacting sharp corners, or by rubbing against some object or hot surface. Place wiring away from oil pipe.
(20)Relieve all pressure in air, oil or water systems before any lines, fittings or related items are disconnected or removed. Always make sure all raised components are blocked correctly and be alert for possible pressure when disconnecting any device from a system that utilizes pressure. (21)Do not operate a truck if any rotating part is damaged or contacts any other part during operation. Any high speed rotating component that has been damaged or altered should be checked for balance before reusing.
(16)Be sure all protective devices including guards and shields are properly installed and functioning correctly before starting a repair. If a guard or shield must be removed to perform the repair work, use extra caution. (17)Always support the mast and carriage to keep carriage or attachments raised when maintenance or repair work is performed, which requires the mast in the raised position. (18)Loose or damaged fuel, lubricant and hydraulic lines, tubes and hoses could cause fires. Do not bend or strike high pressure lines or install ones which have been bent or damaged. Inspect lines, tubes and hoses carefully. Do not check for leaks with your hands. Pin hole (very small) leaks could result in a high velocity oil stream that will be invisible close to the hose. This oil could penetrate the skin and cause personal injury. Use cardboard or paper to locate pin hole leaks. (19)Tighten connections to the correct torque. Make sure that all heat shields, clamps and guards are installed correctly to avoid excessive heat, vibration or rubbing against other parts during operation. Shields that protect against oil spray onto hot exhaust components in event of a line, tube or seal failure, must be installed correctly.

2.2 Main Electrical Components 2.2.1 Key switch The diesel model uses a distributor type injection pump. Its starter switch is equipped with an automatic fuel cut engine stop mechanism. The gasoline model is also equipped with an automatic fuel cut engine stop mechanism. (Key switch with anti-restart lock) This key switch has an anti-restarting function. This switch has a built-in anti-restart lock, so the key switch cannot be turned from the | (ON) to the (START) position while the engine is running. This prevents engine trouble or starter breakage caused by an operator's improper operation when starting the engine. The gasoline and diesel models use the same key switch. On the diesel model, the key switch is electrically connected to the engine so that the | (ON) key switch position turns on the glow plugs. (OFF) (ON) M

Recharge the battery until its voltage and S.G. stabilize and remain constant for more than 2 hours. A cell with a low S.G. may Charge the battery to adjust the electrolyte S.G. It should read cause a short circuit. between 1.280 and 1.265. If the difference in S.G. is It is caused when electrolyte If the difference in S.G. is more than 0.040 and a low S.G. is more than 0.040. leaks or electrolyte rate is too found in any of the cells, replace the battery with a new one. high or too low. Conduct a high current discharge test after leaving the battery for 12 to 96 hours.
4.2 Specific Gravity Reading and State of Charge To tell whether a battery is fully charged, check the electrolyte S.G. of each cell with hydrometer or the electrolyte reduction speed. If the electrolyte in battery cell decreases to the level where the pole plates are exposed within one month, it may be overcharged. If the electrolyte amount remains sufficient for more than three months, the battery may be charged less.
4.3 Charging Precautions (1) In slow charging, the charging current should be about 1/10 the capacity of the battery being charged. (2) In quick charging, the battery capacity in ampere (A) should not be exceeded. (3) During charging, adjust the charging current so that the electrolyte temperature does not exceed 45째C (113째F). (4) When connecting cables to battery terminals, always connect the (+) terminal first, and when disconnecting, remove the (-) terminal first. (5) Ventilate well during the battery charge because hydrogen gas is generated.
