Written for the Manitou MRT 1850 Plus, 2150 Plus and 2540 Plus telescopic handlers and the PLUS-E3 version of each (six variants in all), this 198-page operator manual PDF carries Manitou reference 648665. Safety and operating instructions open the book. The Description chapter follows; it is the largest in the manual and works through cab controls, identification plates, external stickers and the technical specifications for every model. Maintenance fills roughly a third of the pages with the servicing schedule, filter and belt changes and occasional maintenance, and a closing chapter on optional attachments adds their technical data and an electrics diagram. Clean your air filter cartridge every 500 hours, replace the security cartridge at 1000, and change the fuel filter and pre-filter at 1500. Service stalls when nobody knows which hour mark applies. You buy it once, and the bookmarked, text-searchable PDF stays yours for as long as that MRT is in your fleet.

Manitou MRT 1850, 2150, 2540 Plus Common Problems This Manual Covers
Manitou MRT 1850 Plus engine struggling to start in cold weather despite preheating cycle
Check that preheating has fully completed before cranking, following the starting procedure on page 18. In cold weather, apply the cold weather operation and transmission protection steps on page 19 before moving off. Verify battery voltage is above 12.3 V and recharge below that threshold per page 144.
Manual Section: Starting the Lift Truck p. 18Battery voltage low and engine slow cranking after a lengthy lay-off period
Measure battery voltage with the engine off and recharge the battery if it reads below 12.3 V, per page 144. Start the engine and measure regulator output against 13 V to 14.7 V; a reading outside that range points to the electrical circuit. Follow the putting back into operation steps before returning to work.
Manual Section: Maintenance p. 144Hydraulic oil filter and delivery filter cartridges overdue at 500 hour service
Replace the hydraulic oil filter cartridge (exhaust) and the delivery filter cartridge every 500 H, and the hydraulic oil filter cartridge (intake) every 1000 H, per the schedule on pages 119 and 120. Change the transmission oil filter at the same 500 H service. Refill capacity for hydraulic and transmission oil is 210 L on page 122.
Manual Section: Maintenance p. 119Load status indicator warning when taking up a load near the geometric limits
Stop the movement and verify the load weight and center of gravity before going further. Check the maximum rated capacity for your exact model in the Technical Specifications, since the MRT 2540 rating differs from the 1850 and 2150. Bring the load back within the geometric limits covered in the Load Handling section before resuming.
Manual Section: Load Handling p. 34Chain stretched with lateral plate profile wear and tension out of adjustment
Inspect the chain along its full length for wear and stretching, paying close attention to the lateral plate profile. Check elongation using the Chain Maintenance procedure, then adjust chain tension as that section describes. If wear or stretching is beyond the limits given there, fit original replacement parts rather than adjusting further.
Manual Section: Chain MaintenanceOptional heater will not start, or cuts out with flame failure after ignition
Check supply voltage against the heater voltage limits in the Heater Troubleshooting section before anything else. Run the diagnostic test described there to pin down no start, flame failure or overheating. Replace the heating fuel filter (combustion) if it has passed its 1000 H interval on page 121, and the heating fuel filter at 1500 H.
