Did you know that a heavy machine can look ready for work from a distance, but appearances can be deceptive?

Before starting a heavy machine, you need to develop the habit of looking beyond the paint, climbing into the operator’s position with a clear mind, and asking yourself a simple but important question: Is this machine actually safe and ready for the task ahead?

A machine may have enough fuel and a powerful engine, yet a loose hose, low fluid level, damaged tire, faulty warning light or leaking hydraulic system can turn an ordinary working day into a dangerous situation.

Now at Machinery Training Uganda Institute, trainees are encouraged to understand that responsible machine operation begins before the engine starts moving the equipment.

Let’s reflect on some of the things you must do before starting a heavy machine

Your first check begins from the outside

Before you climb into the operator’s seat, take a slow walk around the entire machine and observe its general condition. This is not the time to rush because a careful visual inspection can reveal problems that may not be obvious once the engine is running.

Look underneath the machine for signs of oil, fuel, coolant or hydraulic fluid leakage, while also checking the body, attachment, steps, mirrors and other visible components for damage.

If you notice something unusual, do not simply assume that it was already there or that someone else will deal with it; a professional operator develops the discipline of identifying and reporting defects before they become bigger problems.

Check the engine area carefully

Once you have completed the general walk-around, pay particular attention to the engine compartment and the areas where important fluids and components are located.

Depending on the type of machine, you may need to check engine oil, coolant, hydraulic oil and fuel levels according to the manufacturer’s instructions.

These checks should be carried out using the correct procedure because fluid levels can give you important information about the condition of the machine.

For example, an unusually low level may indicate a leak or another mechanical problem that needs attention before operation. You should also look for loose connections, damaged hoses, worn belts and anything else that appears different from the normal condition of the machine.

Look closely at hydraulic components

Hydraulic systems do much of the heavy work on machines such as excavators, loaders, graders and other hydraulic equipment, which means their condition deserves serious attention before operation.

Inspect hydraulic hoses, pipes, fittings and cylinders for visible damage, cracks, excessive wear or signs of leakage, particularly around connection points.

A small leak should not automatically be treated as harmless simply because the machine still appears to operate normally. Hydraulic pressure can be extremely high, and a damaged component can create both mechanical and safety hazards.

If you identify a serious hydraulic fault, the correct response is to stop and report it rather than attempting to continue working and hoping the problem disappears.

Check the tires, tracks and undercarriage

The part of the machine that remains in contact with the ground deserves just as much attention as the engine.

If you are operating a wheeled machine, inspect the tires for damage, abnormal wear and appropriate inflation according to the manufacturer’s requirements, while also checking for objects that may have become lodged in them.

If you are operating a tracked machine, examine the tracks and undercarriage for obvious damage, excessive looseness or anything that could affect safe movement.

Remember that stability depends greatly on the condition of the machine’s contact with the ground, particularly when you are working on uneven terrain, slopes or construction sites where ground conditions can change quickly.

Do not forget the attachment

An operator can sometimes become so focused on the engine and cab that the attachment is overlooked, yet the bucket, forks, blade, boom, arm or other working equipment is one of the most important parts of the machine.

Before operation, inspect the attachment for cracks, excessive wear, loose components or other visible damage, and make sure the relevant pins, connections and locking mechanisms are correctly secured.

If you are using a forklift, for example, the forks and their locking arrangement require careful attention because they are directly responsible for supporting the load.

On an excavator, the bucket, teeth, pins and hydraulic cylinders should be observed before work begins. The exact checks vary with the machine, but the principle remains the same: never assume the working attachment is safe simply because the machine itself starts.

Check your operator’s area

When you enter the cab, your inspection continues. Adjust your seat and mirrors so that you can operate comfortably and maintain the best possible visibility around the machine, then make sure the seat belt is in good condition and ready for use.

Look at the controls and pedals to ensure that nothing appears damaged or obstructed, and check that the cab is reasonably clean and free from unnecessary objects that could interfere with operation.

Good visibility is particularly important on busy worksites because people, vehicles, materials and other machines can enter your working area unexpectedly. A professional operator should never begin work while struggling to see the area around the machine.

Turn your attention to the dashboard

The dashboard gives you another important opportunity to identify problems before the machine begins working.

When the ignition is switched on according to the manufacturer’s procedure, pay attention to the warning lights, gauges and indicators rather than immediately starting the engine and ignoring what appears on the panel.

You should understand the normal readings and warning indicators for the machine you are operating because an unfamiliar warning light can provide an early indication of a problem.

If a critical warning remains illuminated or a gauge shows an abnormal reading, do not simply cover the problem by continuing to operate. Stop, consult the appropriate machine information and report the issue when necessary.
