Engine oil and filter change
Engine · every 500 hours or every year
Manitou's service chart puts the engine oil drain and oil filter change at every 500 hours or 1 year. The first service is mandatory near 500 hours or within 6 months. After 10 cumulative hours of stationary DPF regeneration the oil is diluted by fuel, so change it then too.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Engine oil | 1 | Stage IV: 10W-40 Evology API CJ-4, ≈7.5 L. E3: Manitou API CH-4 oil, ≈10.9 L. Aztec Oils match: EMPROTEC EHPD 10W-40 | check your handbook |

Step-by-step
- Park on level ground, run the engine at idle for a few minutes, then stop it. Open the engine bonnet and the lower cover and take out the access door.
- Put a container under the drain hole, undo the drain plug (you can screw on the drain hose) and take off the filler cap so it drains fully.
- Unscrew and bin the oil filter and its seal, wipe the filter head and lightly oil the new filter's seal.
- Screw on the new filter by hand. Refit the drain plug.
- Refill with the recommended oil, run briefly, stop and check the dipstick.
- After the service, reset the maintenance counter on the display (XPRT, then RESET, then MAINT) as the manual says.

Known problems
First service is mandatory
Manitou says the first service is compulsory at about 500 hours or within 6 months of going into service, whichever comes first.
Maintenance counter
On Stage IV machines the display warns at 480 hours, counts down 20 hours, then lights the spanner. Reset it on the XPRT menu after the service.
Two generations
Filter numbers, oil quantities and some intervals changed between the E3 and Stage IV machines. Where the list gives both, the Stage IV number is in the field and the E3 number in the note.
Repair guides
- Cleaning and greasing the boom wear pads (Manitou MT 1840, MLT 625, MT 1335) (Easy, 30 to 45 minutes): Groaning, juddering or jerky boom extension and retraction, dry or scored boom sections, or the scheduled pad service is due. The pads are what the telescopic sections slide on, so a dry boom wears them quickly.
- Checking wheel nut torque and tyres (Manitou MT 1840, MLT 625, MT 1335) (Easy, 30 minutes): Loose or clicking wheel, wheel nuts that keep working loose, tyre damage, or after any wheel has been off.
- Fuel pre-filter, fuel filter and bleeding (Manitou MT 1840 and MT 1335) (Moderate, 45 minutes): Water in the pre-filter bowl, loss of power, rough running, hard starting, or after a filter change or running out of fuel.
The full step-by-step guides are in Farmyard Workshop once you add your telehandler.
