SCREEN WIPER.
The arm of a suction screen-\viper should never be worked by hand unless the thumbscrew or valve is released. If the arm is forced across the screen with the valve closed, interior leaks may be caused and opera-
j tion by the engine later will be afi fected. Screen-wipers do not operate I without lubrication indefinitely, and | in the absence of oil or grease the I leather packing which usually forms j the moving unit in the suction cham- ! ber will not make an airtight fit in ! the barrel. Half a dozen drops of oil ! injected every three months will prej vent the plunger from becoming dry.
