If your AVANT Compact Loader engine won't crank, it could be due to several reasons: the main switch might be off (turn it on), the battery could be discharged (check and charge it), a fuse might be blown (check fuses and contact service if it blows again), or the battery cables may be poorly connected (check, clean, and retighten them if necessary).
What to do if AVANT 640 Compact Loader engine cranks but doesn't start?
If your AVANT Compact Loader's engine cranks but doesn't start, consider these possibilities: * Check if you have the correct type of fuel and enough of it. * Ensure the engine is getting fuel; the fuel filter or fuel line may be clogged. * If it's cold, hold the ignition key in the glow position longer, and extend starting time up to 5 seconds. * Make sure the auxiliary hydraulics control lever is in the center (neutral) position. * The battery could be discharged or damaged; jump start it or replace it if necessary.
How to fix AVANT 640 Compact Loader engine overheating?
To fix an overheating AVANT Compact Loader engine: * Clean the radiator and fan from the engine side. * Add coolant if the coolant level is low. * Check the coolant pressure reservoir cap for tightness and inspect the cooling system, hoses, and connections for leaks.
Why is the hydraulic system overheating on my AVANT Compact Loader?
An overheating hydraulic system in your AVANT Compact Loader can be caused by: * Low hydraulic oil level (check and refill). * A clogged oil cooler (clean the cooler and fan). * A faulty fan (check, clean, and repair if necessary). * Restricted hydraulic oil flow (ensure the auxiliary hydraulics valve is completely opened when using high flow attachments and adjust the lever locking plate if necessary). * An overloaded hydraulic system (use the attachment at a lower engine rpm, use with 1-pump setting, and check the attachment for faults).
What to do if AVANT Compact Loader doesn't move after releasing the parking brake?
If your AVANT Compact Loader doesn't move after releasing the parking brake, it could be due to: * A bad connection on the wiring of the parking brake switch, a blown fuse, or a faulty switch (check wires, fuse, and switch, repair if necessary. Contact service). * Low hydraulic charge pressure (contact service for pressure check). * A faulty solenoid valve (check and replace if possible. Contact service).
