Pre start-up checks

Pre-start up checks or specified by the manufacturer prior to operating the equipment.

It is important that you perform a pre-start check of the skidder to make sure it is safe to operate, and that components of the machine are not damaged.

Check that fluid has not leaked out, and there has been no tampering with the machine.

CAUTION! If a machine is started and operated without a pre start-up check, and there is a component failure it may result in:

• very expensive damage to the machine;
• down time of machine and operator;
• loses of income or injury to the operator.

Therea are two types of checks you should complete before start the engine.

1. Pre-start walk around checks.

• Walk around the skidder and check that the tyre pressures are at the recommended pressure for each axle otherwise stability, traction, ride and tyre life will be affected. Refer to operator’s manual or service chart for correct specifications.
• If operating a track machine, ensure pleats are tight and track chain is adjusted to the correct tension.
• Check wheel nuts are tight by looking for signs of movement between the nut and rim.
• A shiny ring around the wheel nut seat will indicate a loose wheel nut.
• Loose wheel nuts require urgent attention, as major repairs will result if the machine is allowed to work.
• Check there are no oil leaks or oil on the ground under the belly plates.
• Check for fresh oil marks on the crane components.
• Look for unusual wear patterns on the chassis, crane or cabin.
• Look for signs of cracking on the chassis, crane or cabin.
• Check bolts that hold the main pins in are on the crane.
• Inspect hydraulic hoses and fittings for any leaks or damage.
• Check the machine for loose steps, hand rails, guards, lights etc.

2. Fluid levels and complete engine bay checks.

• Fuel level;
• Engine oil level;
• Hydraulic oil level, Caution! Release any stored pressure from the system before filling;
• Coolant level;
• Observe whether the machine is on level ground;
• This is to determine accurate oil level checks;
• Check the colour of the oil (e.g.) water condensation will turn the oil milky white or grey.

Remember: Cleanliness is essential when checking or topping up any oil reservoir.

Important safety note:

It is extremely dangerous to remove the cap from a hot radiator! You can be seriously burnt.

Only remove the radiator cap when it is cool enough to touch with bare hands.

Slowly loosen cap to first stop to relieve pressure before removing completely.

NEVER STAND WITH YOUR HEAD OVER THE RADIATOR CAP.

• If you need to check the coolant level in-between shifts, look for the level in the radiator expansion tank as this is usually a clear indicator. 
• If header tank is not clear or not available, slight squeezing of the top radiator hose, the presence of water should be felt.
• Pre cleaner for air cleaner
• Check the radiator and oil cooler screen is clear of dust and debris.
• Inspect fan blades and drive belts for correct tension.
• Check battery is clamped firm and the terminal connections are tight.

Starting the Machine

On starting the engine it is important to test the operation of its functions.

• Test the brake system.
• Test the steering from side to side.
• Test hydraulic functions work correctly.
• Test all lights are in working condition.
• Test all communication systems in the machine work.
• Observe visual and audio warning devices.
• Check that gauges give the correct reading.
• Check onboard computer systems function correctly.
• Checks relating to start-up and shut-down procedures may involve safety mechanisms
  (e. g. start up procedure, door closed, sitting in seat, park brake on before machine will start).
• Check location of tools / equipment and machine security.
