Pro Tips from the Field

Wisdom from experienced Telehandler operators.

1

Always use the correct grade of oil and fluids as specified by the manufacturer. Using the wrong fluids can cause serious damage.

2

Regularly inspect the boom for cracks or damage, especially around welds. Early detection can prevent catastrophic failures.

3

When operating on uneven terrain, use caution and adjust the boom angle to maintain stability. Never exceed the load capacity.

4

Keep the machine clean, especially around the engine and hydraulic components. This helps prevent overheating and makes it easier to spot leaks.

5

Before operating, always walk around the machine and check for any potential hazards, such as overhead obstructions or ground conditions.

6

If you notice any unusual noises or vibrations, stop the machine immediately and investigate the cause. Ignoring these warning signs can lead to more serious problems.

7

When changing hydraulic fluid, be sure to clean the hydraulic tank thoroughly to remove any sediment or contaminants. This will help prolong the life of the hydraulic system.
