Need help?Do you have a question about the Manitou M26-2 D ST5 S1 EU and is the answer not in the manual?
This document is an operator's manual for MANITOU M26-2, M26-4, M30-2, M30-4, M40-2, M40-4, M50-2, and M50-4 D ST5 S1 EU lift trucks. It provides comprehensive information on operation, handling, equipment, maintenance, and safety recommendations.
The manual emphasizes the importance of reading and understanding all instructions before using the machine to prevent accidents. It highlights that the machine's equipment level varies based on options and country of sale, and that MANITOU reserves the right to modify models without updating the manual. The MANITOU network of qualified professionals is available for support. The manual is an integral part of the machine and should be kept in its storage location for easy reference.
The product may expose users to lead, which is known to cause cancer and birth defects. Breathing diesel engine exhaust is also linked to cancer and reproductive harm. Users are advised to operate the engine in well-ventilated areas, vent exhaust outdoors if in enclosed spaces, avoid tampering with the exhaust system, and limit idling.
Exposure to crystalline silica (found in sand, soil, and rocks) can lead to silicosis. Users must comply with workplace regulations, wear approved respiratory protection, or use water spray to control dust. OSHA's "29 CFR 1929.1153" rule addresses the significant risk of chronic silicosis for workers exposed to inhaled crystalline silica.
Proper site management is crucial to reduce accident risks, ensuring the ground is even, slopes are not excessive, and pedestrian traffic is controlled. Only qualified and authorized personnel, with written authorization, may operate the machine. The manual strictly forbids foreseeable misuse and highlights the importance of considering operator behavior (e.g., apprentices, teenagers, handicapped persons) when assessing suitability.
The machine is a lift truck designed for handling, moving, storing, or transporting loads. It meets STATIC TEST COEFFICIENT of 1.33 and DYNAMIC TEST COEFFICIENT of 1, as per ISO 3691-1. Before commissioning, the company manager must ensure the machine is appropriate for the work and perform necessary tests. Environmental conditions, such as frost protection and lubricant adaptation, must be considered. Special equipment is available for dusty, flammable, or potentially explosive environments. The machine is designed for outdoor use and indoor use in well-aerated premises.
The machines comply with Directive 2004/108/EC (UK: Electromagnetic Compatibility Regulations 2016) and EN 12895. Correct operation is not guaranteed in areas where electromagnetic fields exceed 10 V/m. Directive 2002/44/EC requires minimizing operator exposure to excessive vibration doses. Tips for reducing vibration include selecting suitable machines and attachments, adjusting seat and cab suspensions, inflating tires correctly, adapting operating speed to site conditions, and maintaining flat running surfaces. Unauthorized modifications to the machine's structure or settings (hydraulic pressure, limiter calibration, engine speed, attachments, alarm systems) are prohibited, as they invalidate manufacturer responsibility. For France, non-approved machines on public highways must comply with the highway code (Article R311-1) and be fitted with an operating license plate.
The operator's manual must be kept in good condition and readily available. Operators must read the manual carefully and report any illegible or damaged plates/stickers. Only qualified and authorized personnel may use the machine. Operators are prohibited from performing repairs or adjustments unless trained. Daily and weekly maintenance must be performed with the engine off and ignition key removed. Tires must be appropriate for the ground type; damaged or excessively worn tires are unsafe. Foam-inflated tires are prohibited without prior authorization. Operators are responsible for cleaning the machine to prevent fire risks from flammable material accumulation. Unauthorized modifications are prohibited. Lifting or carrying people is forbidden.
Before starting, daily maintenance must be performed. The cab, floor, lights, turn signals, windshield wipers, rear-view mirrors, and audible alarm must be checked. The seat must not be adjusted while moving. Operators should familiarize themselves with controls, wear appropriate clothing and protective equipment, and use handles and steps when entering/exiting the cab. Headphones are prohibited. Hands and feet must be clean. The seat and safety belt must be adjusted correctly. Controls are for intended purposes only. Passengers are prohibited. Site safety regulations must be followed. Work lights are required in dark conditions. Personnel must be kept clear of the working area. The machine should not be operated on transverse slopes without following specific instructions. When traveling on longitudinal slopes, drive and brake gently, with forks downhill when unladen and uphill when laden. Machine dimensions and load must be considered in narrow passageways. Load bridges, footbridges, floors, or freight lifts must be checked for suitability and sound working order. The ground must be stable and firm before lifting loads.
The machine must only be started or maneuvered from the driver's cab with the seatbelt fastened. Pushing or towing to start is prohibited. Emergency battery use requires matching characteristics and correct polarity (positive terminals first). Failure to respect polarity can damage the electrical circuit. Battery electrolyte is explosive; avoid flames and sparks. Never disconnect a battery while charging. Hoods must be closed and locked. For gas carburization, open the gas bottle. The forward/reverse selector must be in neutral. Turn the ignition key to position I for electrical and preheat systems. Check fuel level. Turn the ignition key fully to start, then release to idle. Do not engage the starter for more than 15 seconds. Ensure all signal lights on the control panel are off. Check control instruments regularly. Stop the engine immediately if an instrument shows an incorrect display.
Operators must be aware of risks like losing control and stability. In case of overturning, remain fastened in the cab. Traffic regulations and machine capacities must be observed. Drive with forks in transport position (300 mm from ground, carriage sloped backward). Loads must be balanced and anchored. Pallets and cases must be in good order. Engine speed must not exceed technical data when loaded. Drive smoothly and reduce speed when transporting loads. Do not maneuver with the mast raised unless absolutely necessary, and then with extreme caution. Take bends slowly. Drive slowly on damp, slippery, or uneven terrain. Brake gently. Use the forward/reverse selector only from a stationary position. Do not drive with foot on the brake pedal. Hydrostatic steering is sensitive; turn gently. Do not leave the engine running unattended. Do not leave the cab with a raised load. Maintain good visibility. Use rear-view mirrors frequently. Drive around obstacles. Avoid ditch edges or steep slopes. Simultaneous use of two machines for heavy loads is dangerous and requires risk analysis. The ignition switch has an emergency stop.
Never leave the ignition key in the machine unattended. When stationary, place forks on the ground, apply the parking brake, and set the forward/reverse selector to neutral. Ensure the machine is not obstructing traffic or near railway tracks. For prolonged parking, protect from bad weather, check antifreeze, and lock all accesses. Park on flat ground or inclines less than 15%. For gearboxes, place the gear lever in neutral. Lower forks to the ground. Close hydraulic attachments. After intensive work, idle the engine for a few moments to cool down. Stop the engine with the ignition switch. Remove the ignition key. Activate the battery cut-off at the end of the day. For gas carburization, close the gas bottle and let the engine stop naturally to eliminate fuel in the feed tube.
Non-approved machines on public highways must comply with French Highway Code Article R311-1. Operators must comply with road legislation. Optional solutions are available from dealers. Ensure the revolving light is on and working. Check lights, turn signals, and windshield wipers. Switch off worklights. Place attachment 300mm from the ground. Never coast in neutral on a slope to preserve engine brake, as this can lead to loss of control and damage.
Comply with local regulations for driving with a front-mounted attachment. If authorized, protect sharp edges, ensure the attachment is not loaded, and does not mask forward lights.
Observe local regulations for maximum travel speed, braking, and trailer weight. Connect electrical equipment and ensure the trailer's braking system complies with legislation. If pulling a trailer with assisted braking, the tractor machine must have a trailer braking mechanism. Vertical force on the towing hook and authorized gross vehicle weight must not exceed manufacturer limits. Consult your dealer if necessary.
Only MANITOU-approved attachments should be used. Ensure the attachment is appropriate for the task, correctly installed, and locked. Comply with load chart limits and rated capacity. Never lift a load in a sling without the proper attachment. Know the load's weight and center of gravity before lifting. For irregular loads, determine the transverse center of gravity. Do not handle loads heavier than the effective capacity defined on the load chart. Be extra vigilant with loads having a moving center of gravity. The transverse attitude of the machine must be horizontal with the mast down. Position the machine so the bubble in the level is between the two lines.
Advance the machine perpendicular to the load with forks horizontal. Adjust fork spread and centering. Never lift with a single fork. Beware of crushing limbs when adjusting forks. Move forward slowly, bringing forks to the load. Lift the mast slightly if necessary. Bring the load into transport position and tilt backward for stability.
Do not raise the mast without checking the transverse attitude. Ensure good visibility. Ensure forks can easily pass under the load. Keep the mast vertical, advance, and raise forks to the load level. Maneuver gently to bring forks to the load stop. Apply parking brake and set forward/reverse selector to neutral. Lift the load slightly and tilt the carriage backward for stability. Reverse carefully to free the load. Lower the mast to transport position.
Approach the pile with the load in transport position. Raise the mast until the load is higher than the pile. Move forward carefully until the load is over the pile. Apply parking brake and set forward/reverse selector to neutral. Place the load in a horizontal position by tilting the mast forward. Lay it down on the pile, checking positioning. Reverse slowly and carefully to free the forks. Set forks into transport position.
Ensure the work area is ventilated. Wear suitable clothing, avoid jewelry, and tie back hair. Before any work, switch off the engine, apply parking brake, and remove the ignition key. Read the manual carefully. Repair all leaks immediately. Dispose of materials and spare parts safely. Be careful of burning and splashing risks from exhaust, radiator, engine, and cab heating vents. Perform periodic service as per the schedule to maintain warranty. Record all maintenance in a logbook, including date, personnel, operation type, frequency, and part numbers for replaced elements.
Use recommended lubricants. Do not fill the fuel tank when the engine is running. Fill only in specified areas and not to maximum level. Do not smoke or approach with flame when filling.
Work on the load handling hydraulic circuit is forbidden except for operations described in the maintenance chapter. Do not loosen unions, hoses, or hydraulic components under pressure. Changing settings or removing balancing/safety valves is dangerous. Hydraulic accumulators are pressurized units; removing them is dangerous. Such operations must only be performed by approved personnel.
Do not short-circuit the starter relay. Disconnect the battery before working on the electrical circuit. Do not place metal items on the battery.
Disconnect the battery before welding. Connect the negative cable directly to the part being welded to avoid high current passing through the alternator. Do not weld or apply heat to an assembled tire. Disconnect electronic control units to prevent damage.
Clean the machine before any intervention. Close and lock all accesses. Avoid articulations, electrical components, and connections during washing. Protect components susceptible to water, steam, or cleaning agents. Clean off fuel, oil, or grease.
Transporting the machine involves real risks. Towing, slinging, or transporting must follow specific instructions.
Recommendations for extended periods out of service (up to 12 months) must be performed by your dealership. Clean the machine, check for leaks, replace worn parts, wash painted surfaces, and touch up paintwork. Shut down the machine, retract mast cylinder rods, and release hydraulic pressure.
Empty and rinse the DEF tank. Replace the DEF feed pump filter. Fill with new DEF. Start the machine to pressurize the circuit and bring it to working temperature. Stop the engine, check, and top up DEF level.
Contact your dealer for engine protection procedures. Fill the tank with fuel. Replace coolant. Run the engine at idling speed for a few minutes, then switch off. Replace engine oil and filter. Run the engine briefly to circulate oil and coolant. Disconnect and store the battery. Block the outlet with waterproof tape. Remove drive belts. Disconnect and insulate the engine cut-off solenoid.
Set the machine on axle stands, release the parking brake. Protect cylinder rods from corrosion. Wrap tires. Cover with a waterproof tarpaulin if stored outdoors.
Remove waterproof tape from orifices. Refit and reconnect the battery. Remove cylinder rod protection. Perform daily maintenance. Put on handbrake and remove axle stands. Drain and clean fuel tank. Fill with clean diesel. Replace fuel filter and pre-filter. Empty and rinse DEF tank, then fill with new DEF. Refit drive belts and adjust tension. Turn the engine over with the starter to raise oil pressure. Reconnect the engine cut-off solenoid. Lubricate the machine completely. Start the machine following operating and safety instructions. Perform all boom hydraulic movements, concentrating on ends of travel.
Consult your dealer before disposal. Metals are 100% recoverable. Plastic parts are identified for recycling. Rubber (tires, seals) can be ground for cement or reusable granules. Glass items can be removed for processing. MANITOU's network helps limit pollution by organizing collection and processing of used oil and batteries.
All stickers and safety plates must be legible and replaced if damaged.
