Mustang AL 106, AL206, AL306 Common Problems This Manual Covers
Engine cranks but will not start
A loader that turns over without firing, or dies shortly after starting, usually comes down to fuel delivery, a safety interlock, or the starting circuit. The Engine section walks through starter and drive coupling removal and installation for deeper diagnosis.
Manual Section: Engine p. 110Weak or slow hydraulic functions
Lift or steering functions that stall under load point to low or contaminated oil, a clogged filter, or pump wear. The Hydraulics section covers work hydraulics and hydrostatic drive troubleshooting; work system pressure should test at 207 bar plus or minus 7 (3000 psi plus or minus 100).
Manual Section: Hydraulics p. 182Overheating or repeated shutdowns
Rising temperature or nuisance shutdowns during work usually trace to low coolant, a dirty radiator or oil cooler, or restricted airflow. The Cooling System section covers radiator and oil cooler removal for both the AL 100 and the AL 200 and 300 series.
Manual Section: Cooling System p. 148Brake drag or weak braking
Poor stopping or dragging brakes, most often flagged on the AL 300 series, are set right through the service brake adjustment procedure. The Axles section gives the adjustment and troubleshooting steps for each series.
Manual Section: Axles p. 160Battery drains or electrical faults
Accessories that quit or a battery that goes flat overnight point to a charging fault, poor connections, or a switch problem. The Electrical System section covers battery removal and installation and the machine controller LED and indicator logic.
Manual Section: Electrical System p. 308Belt slip or squeal at cold start
A squeal on startup or a slack drive belt reduces charging and cooling performance. The Maintenance section sets V-belt deflection at no more than 8 mm (5/16 in.) and covers the check and adjustment procedure.
Manual Section: Maintenance p. 32Frequently Asked Questions
