11. EXPLANATION OF COMPONENTS 11.11 TOOL BOX This is inside the cover at the left of the machine. It is used for storing tools. 11.12 HANDLING ADDITIONAL HEATER If more powerful heating is required during cold weather, use an additional heater. Control switch 1 also acts to regulate the air flow. Control switch 1 can be used to switch the air flow to 2 levels. When control switch 1 is turned to the OFF position, the electric power is cut and the heater stops. NOTICE When using the heater, check the heater piping from time to time. If there is any leakage of water from the heater piping, the level of the engine cooling water will go down. This brings the danger that the engine will seize up.
When not using the heater in summer, close valve 1 at the hot water take-off port. 2-23
