Material:
Kerosene or solvent
Clean cloth (WP 0079, Table 1, item 23)
Equipment condition:

A build-up of dirt on the fan blades will reduce the air supply and cause faulty heater operation. Clean the
diesel heater fan blades as follows:
WARNING
Mechanical and electrical hazard. Before opening up the top cover of the heater to
access the fan blades, be sure the heater switch is OFF and the power cord is
unplugged from the power source and the heater. Failure to observe this warning
may result in injury if the fan operates or injury or death from electrical shock.
1. Make sure the heater switch is OFF.
2. Make sure the heater power cord is unplugged from the power source and from the heater.
3. Open the top cover of the heater by unsnapping the three "screws" at the front of the cover and
lifting the cover (see Figure 2). (The three "screws" do not screw out. They are actually snaps
that snap in and out of clips behind the cover. Pull the cover out at the screws to unsnap the
screws from the clips.)
