STORING REFUSE IN THE BODY
Heil does not recommend storing refuse in the body overnight. The different types of debris and corrosive elements usually
collected can cause severe corrosion inside the body decreasing the life of your body. This corrosion can affect unloading
and decrease the structural life of the body. In addition, storing refuse in the body overnight can increase the risk of fire.
MAINTENANCE/LUBRICATION INFORMATION
Before performing maintenance, check the work area carefully to find all the hazards present and make sure all safe
guards or safety devices are in place to protect all persons and equipment involved.
WINCH GEAR OIL
When the unit has a winch option, check the level of the winch’s gear oil every 40 hours of operation. Fill as needed with
AGMA Grade 5 EP (90wt.) for an 8,000 lb. winch and AGMA Grade 7 EP (140 wt.) for a 12,000 lb. winch.
