Start by checking the fluid levels including engine oil, hydraulic fluid, and coolant. Inspect the tires for proper inflation and any visible damage. Ensure that all lights and signals are operational. Check for any hydraulic leaks and ensure the load chart is legible and in place.
Verify the battery connections are secure and free of corrosion. Check the fuel level and ensure the fuel shutoff valve is open. Inspect the fuses for any that may be blown. If these steps do not resolve the issue, consult the service manual for further diagnostics.
Check for any visible leaks in the hydraulic hoses and connections. Ensure that the hydraulic fluid is at the correct level and is not contaminated. Listen for unusual noises when operating the hydraulic controls, which might indicate a blockage or pump issue.
Perform daily checks of fluid levels, tires, and safety features. Conduct a more thorough inspection and service every 250 hours, including oil and filter changes, lubrication of moving parts, and inspection of all belts and hoses.
To adjust the forks, lower them to the ground, and ensure the forklift is turned off. Manually slide the forks to the desired position, ensuring they are locked in place with the retaining pins. Make sure both forks are aligned to maintain balance while lifting.
Common signs include slipping gears, unusual noises during operation, and difficulty in changing gears. If these symptoms are present, inspect the transmission fluid for proper level and contamination. Consider professional servicing if issues persist.
Refer to the operator's manual for specific calibration instructions. Typically, the process involves setting the forklift on a level surface, ensuring it is unloaded, and following the calibration prompts on the system display.
Check the coolant level and top it off if necessary. Inspect the radiator and cooling fan for blockages or damage. Ensure the thermostat is functioning correctly. If the problem persists, have a professional examine the cooling system.
Locate the air filter housing, remove the cover, and take out the old filter. Clean the housing of any debris before inserting the new air filter. Replace the cover securely, ensuring a tight seal to prevent dust entry.
Always wear appropriate personal protective equipment (PPE) such as hard hats and high-visibility vests. Perform a pre-operation check, use seat belts, and never exceed the load capacity. Be aware of the surroundings and avoid quick, sharp turns.
