PM-102 Cold Planer Caterpillar

Show/hide table

Water is sprayed from the gun at high pressure and velocity. Do not direct the water jet towards yourself or other people. Personal injury or death could occur.

Clean the tracks, and conveyors. Also clean the rotor. Use the high-pressure water system (if equipped) at the end of operation each day. This cleaning will prevent asphalt or concrete from setting up when the machine is idle. Cleaning of the rotor can be made easier. Leave the water spray system on at the time of moving the machine from the end of the cut to the parking location.

1. Open the water pump compartment access door.
