The air filter of a full-hydraulic guardrail pile driver should be regularly cleaned:

1. Open the rear cover plate of the cab and remove the external air filter element of the air conditioner; take out the internal air filter element of the air conditioner from under the driver's seat. The guardrail pile driver is a type of equipment for pressing steel pipe piles for highway guardrails. This machine is powered by diesel, with a fully hydraulic mechanical transmission. It features easy mobility, high piling accuracy, durability, energy efficiency, and environmental friendliness. It is especially suitable for the field construction of highway guardrail installation, maintenance, and emergency repairs.

2. Please use compressed air to clean the internal and external air filter elements. When installing the internal air filter element of the air conditioner, make sure to insert it with the UP side facing upwards. The internal air filter element of the air conditioner should be cleaned every 500 hours, and the external air filter element every 250 hours.
