Manitou America Z17 GEN:2, 170Z NXT2 Common Problems This Manual Covers
Engine cranks but will not start
Starting trouble on these excavators usually traces to the battery, starter circuit, wiring, or charging system rather than the engine itself. The Adjustment and Repair section covers the electric equipment, wiring diagrams, and the engine start, stop, and battery charging circuits used to isolate the fault.
Manual Section: Adjustment and Repair p. 257Weak or jerky hydraulic movement
Slow, weak, or jerky boom and bucket action often points to a hydraulic pressure or fluid condition problem. The Hydraulic System section gives the circuit schematic and pressure adjustment procedure, with a main relief valve set pressure of 2987 PSI (20.6 MPa) to check against.
Manual Section: Hydraulic System p. 97Loss of digging or lifting power
A drop in digging or lifting force can come from wear inside the hydraulic pump or control valve. The Hydraulic Equipment section walks through removal and reinstallation of the pump, control valve, swing motor, and swivel joint so worn units can be inspected or rebuilt.
Manual Section: Hydraulic Equipment p. 133Track dragging or travel problems
Incorrect track tension and undercarriage wear cause dragging, derailment, and uneven travel. The Adjustment and Repair section covers the undercarriage and controls so tension and worn rollers can be checked and corrected.
Manual Section: Adjustment and Repair p. 257Overheating or low engine output
Overheating and low output are common complaints on hard worked mini excavators. The Troubleshooting section provides diagnostic tables for machine and engine faults, low output, and overheating to narrow down the cause.
Manual Section: Troubleshooting p. 355Undercarriage wear from missed greasing
Skipping daily lubrication of pins, bushings, and the slew bearing accelerates undercarriage wear. The Periodic Inspection and Servicing section lists the service intervals that keep these parts protected.
Manual Section: Periodic Inspection and Servicing p. 347Frequently Asked Questions
