Comprehensive Pre-Operational Check
In order to ensure that your machine is operating safely and efficiently, a proper pre-operational check is important. The pre-operational check covers a number of key components of the machine and helps to identify maintenance issues and repairs that may be required. It is important to assess the conditions observed during your inspection to determine the action required. Appropriate responses could range from immediate removal from service, often maintenance or basic repair that you will be expected to perform, or reporting conditions that will require service later.
A good pre-operational check should include:
GENERAL WALK AROUND
- check for obstacles and hazards
- look for visible fluid leaks or seepage on 'belly pans', component cases and on the ground below the machine
FUEL SYSTEM
- check fuel level visually if you are not sure of gauge operation
ENGINE OIL
- wipe dipstick before checking - some dipsticks have dual markings for idling or engine stopped measurements
COOLANT - *to prevent injury, radiator cap should be removed ONLY when engine is cool*
DRIVE BELTS
- check for proper tension and condition
TRANSMISSION FLUID
- check level with sight glass or dipstick depending on manufacturer - some dipsticks have dual makrings for machine off or idling in neutral
- look for signs of discolouration or sediment
HYDRAULIC SYSTEM FLUID
- check level
- look for signs of discolouration or sediment
HYDRAULIC SYSTEM COMPONENTS
- look for worn, damaged or leaking hoses, cylinders and other components
ELECTRICAL SYSTEM COMPONENTS - *use extra caution when inspecting batteries*
- note any loose or damaged wiring/connections, battery connections/corrosion
- check electrolyte level
AIR INDUCTION
- check air filter preferably by observing restriction indicator - avoid disturbing/removing filters unless necessary
- check pre cleaners if equipped and clean as required
- visually check for secure filter mounting and intake hose condition/connections
UNDERCARRIAGE
- check track tension
- look for bent of missing pads
- watch for missing or loose bolts for pads
- check final drive for leaks
- check sprockets for worn or broken teeth and loose mounting bolts
- inspect bottom and top rollers for excessive wear, damage, and loose bolts
HARDWARE AND ATTACHMENTS
- look for cracks, especially at corners and seams of blade and C-frame
- make sure pins and pin retaining bolts are in place
- inspect locks for cylinders
- check linkages for signs of wear or damage
- inspect compononent mounting hardware
- ensure that the blade is securely mounted
- check that cutting edge and corner bits are secure
- inspect pins and pin retaining bolts/locks for c-frame, blade mounting, cylinders
- inspect component mounting bolts including battery tie downs, alternator, starter check engine mounts, gear case bolts, drive system, guards and metalwork, etc.
- inspect rippers if equipped
SAFETY SYSTEMS
- inspect seat belts
- test lock-outs
- make sure parking break is operational
- check lights, horn, back up alarm, wipers, heater/defrost (if equipped)
- check operation of gauges and warning lights
OPERATOR CONTROLS - *some of these checks require the vehicle to be in motion*
- check operation of throttle
- ensure drive system is functioning
- check operation of brakes - watch for excessive pedal travel, etc.
- check function of blade and attachments
