Repairing a reach truck (a type of forklift used for stacking and retrieving pallets at height in narrow aisles) involves diagnosing and fixing issues related to the mechanical, electrical, or hydraulic systems. These trucks are complex and require proper maintenance and repairs to ensure safe and efficient operation. 

Repairs to reach trucks can vary depending on the type of issue and the specific model. While many minor repairs (such as cleaning the battery terminals or topping up hydraulic fluid) can be done by in-house personnel, more complex problems (such as motor or transmission issues) should be handled by trained professionals or a certified repair service. Regular preventive maintenance is the best way to keep your reach truck in optimal condition and avoid costly repairs down the line.
