      If your AVANT Compact Loader engine won't crank, it could be due to several reasons: the main switch being off (turn it on), a discharged battery (check and charge it), a blown fuse (check fuses, and contact service if it blows again), or poorly connected battery cables (check, clean, and retighten them if necessary).

      An overheating hydraulic system in your AVANT Compact Loader could be caused by several factors: * Low hydraulic oil level: Check and refill the oil. * Clogged oil cooler: Clean the cooler and fan. * Faulty fan: Check and clean the fan; repair if necessary. * Restricted hydraulic oil flow: Ensure the auxiliary hydraulics valve is completely open when using high flow attachments and adjust the lever locking plate if necessary. * Overloaded hydraulic system: Use the attachment at a lower engine rpm, use with 1-pump setting, and check the attachment for faults.
