• Clear insulation away from engine and muffler to avoid fire, ensure proper
ventilation and reduce the chance of insulation getting in the fuel tank.
• Do not run vacuum inside of an enclosed box truck, trailer or building. Doing
this will result in engine damage, exposure to carbon monoxide or fire.
Note: Debris can be sucked into the engine through the air intake
and clog the cooling fins. (See Illust. E)
