1. GENERAL MAINTENANCE INSTRUCTIONS

• The SCR control, like all electrical apparatus, does have some thermal losses. The semiconduc­ tor junctions have finite temperature limits above which these devices may be damaged.
• For these reasons, normal maintenance should guard against any action which will expose the compo­nents to excessive heat, such as steam cleaning; or which will reduce heat dissipating ability of the control, such as restricting air flow.
• The following DO’S and DON’TS should be observed: Any controls that will be used in ambients of 104 °F (40°C) or over should be brought to the attention of Komatsu Forklift Co., Ltd. All external components having inductive coils must be filtered. Refer to Komatsu Forklift Co., Ltd.
• The control should not be steam cleaned. In dusty areas, use low-pressure air to blow off the control. In oily or greasy areas, a mild solution of detergent or denatured alcohol can be used to wash off the control and then blow completely dry with low-pressure air.
