Manitou's 964-page Repair Manual, OEM ID 547954 EN, takes the CD 15 P lift truck down to its crankshaft, along with eleven other variants across the CD and CG P series. This Manitou CD 15 P repair manual PDF pairs wiring diagrams for the electrical circuits with hydraulic schematics, then works through engine disassembly: cylinder head, piston and connecting rod, crankshaft, timing gear and lubrication system. Torque tables back each procedure. Fill the brake circuit with 0.5 L, clean the dry air filter cartridge on a CD 15 P or CD 18 P every 50 hours, and change the engine oil filter on the CG 15 P and CG 18 P at 500 hours. Chasing an ignition or fuel system fault on your truck? The troubleshooting and engine tune-up chapters cover both, plus the electrical system. Bookmarks and a searchable text layer take you straight to the timing gear pages, so your engine rebuild runs to Manitou's own figures.

Manitou CD 15 P to CG 35 P Common Problems This Manual Covers
Manitou CD P diesel engine turns over on the starter but will not start
Check whether fuel reaches the fuel pump, then check for air mixing: retighten fittings, replace packing and bleed air as the chart on page 179 directs. Clean a clogged fuel filter. Never use a free flame for light while hunting leaks (page 581). If fuel is injected, check the glow plug control resistance, injection timing and nozzle; send a defective injection pump to a specialty shop.
Manual Section: Engine Troubleshooting p. 179Starter does not run at all when the starter switch is turned to start
Check the battery first and charge it if discharged; the system is 12 V (page 28). Before working on the starter or wiring, disconnect the battery grounding cable as page 76 requires. Test the starter switch and magnetic switch, replacing either if defective. Repair a starter bush with poor contact, retighten loose connectors or replace broken wire, and send a defective starter to a specialty shop per page 179.
Manual Section: Engine Troubleshooting p. 179Engine idling unstable or rotation hunts at medium speed with rpm surging up and down
Check the fuel pipe for crash damage and the high pressure pipe for cracking, clogging or bending, replacing any damaged pipe following page 180. Inspect the nozzle, uneven compression and a deteriorated governor spring. For unstable high speed, bleed air, clean or replace the fuel filter, and set valve clearance to 0.38 mm hot (page 36) with the engine stopped, since page 580 forbids servicing with the engine running.
Manual Section: Unstable Idling Troubleshooting p. 180Engine overheats with cooling water temperature abnormally high while the truck is working
Check the cooling water level and look for internal or external leakage; replenish, then repair or replace leaking parts per page 181. Adjust a slipping fan belt with the engine stopped, since page 580 forbids servicing with the engine running. Replace a malfunctioning thermostat, clean a stained cooling system or clogged radiator, check engine oil quality and level, and confirm the truck is not overloaded.
Manual Section: Overheating Troubleshooting p. 181Diesel engine exhaust gas abnormal with far too much black smoke coming out
Inspect the air cleaner first and replace a clogged element, then check the air hose for crash damage following page 182. Check the nozzle and repair or replace it if defective. Verify injection timing and adjust it if advanced too much. If the injection pump is defective, bring it to a specialty shop rather than opening it yourself.
Manual Section: Dark Exhaust Smoke Troubleshooting p. 182Engine oil pressure stays too low and the gauge will not rise after startup
Check the oil level and replenish if low, then check oil quality and change to the specified oil if viscosity is wrong (page 183). Inspect crankcase oil for water or fuel mixing and check the fuel and cooling systems if found. Repair or replace a defective relief valve. If pressure stays low, overhaul for a malfunctioning or clogged oil pump, cracked pipe or worn sliding parts.
