Running a JCB 135 HD or 155 HD skidsteer hard without reading the manual is a fast way to miss something expensive. This 192-page Operator Manual (OEM #9831/0450) covers every control, maintenance schedule, and safety protocol from dashboard indicators to daily walk-around inspection checklists. Step-by-step attachment guidelines walk you through handling heavy loads safely, and the fluid capacity tables leave no guesswork on fills. Swap out the main fuel filter every 500 hours and verify the lifting eyes are torqued precisely to 190 N·m before securing any overhead load. Routine maintenance intervals are laid out shift by shift so nothing slips through. Download the bookmarked file, pull it up on your tablet right in the cab, and keep the machine moving.
