4. MAINTENANCE 4. 9 AIR CLEANER MAINTENANCE 1. Daily Maintenance Inspect the air cleaner canister for holes, dents, missing or mis-aligned gaskets. Check all hose clamps for tightness and inspect the hose and vacuator valve for damage (Fig. 4.9A). 2. Servicing Cleaner Element (Fig. 4.9B) DO NOT open unless the indicator indicates a blocked filter or under normal scheduled servicing. 2.1 Unlatch and remove the cover assembly 2.2 Release the seal gently - The filter should be removed gently to reduce the amount of dust dislodged. Move the end of the filter up and down and side to side or twist to break the seal.
2.3 Avoid dislodging dust from the filter - Gently pull the filter off the outlet tube. Avoid knocking the filter against the housing. Cover Assembly Vacuator Valve Inlet 2.4 Always clean the sealing surface of the outlet tube - Dust on the outside diameter of the housing could hinder an effective seal. 2.5 Always clean the inside of the outlet tube - Dirt inside of the outlet tube will reach the engine. It only takes 9 grams of dirt to dust an engine. Latch Safety Filter (Optional) Primary Filter C-653 Fig. 4.9B Outlet 2.6 Check your old filter. Inspecting your old filter will detect foreign material on the sealing surface that may causing leakage.
2.7 Inspect the new filter for seal or pleat damage. 2.8 Insert the new filter properly - The seal area is on the inside of the open end of the primary filter. A new filter has a dry lubricant to aid installation. The critical sealing area will stretch slightly, adjust itself and distribute the sealing pressure evenly. To complete a tight seal, apply pressure at the outer rim of the filter, not the flexible centre. No cover pressure is required to hold the seal. To avoid personal injury: DO NOT charge a frozen battery because it can explode and cause personal injury. Let the battery warm to 60°F.(15.5°C.) before putting on a charger.
2.9 Check connections and ducts for air tight fit - Make sure all clamps, bolts and connections are tight. Check for holes in piping. Leaks here send dust directly to the engine. WARNING 2.10 DO NOT reuse filters by cleaning and reinserting. To avoid personal injury, lower the lift arms, shut off the engine, raise the seat bar and cycle the controls to ensure they are locked. Then, unlatch the seat belt and exit the loader. Do not enter or exit with the engine running unless as specified in this manual or under specific service and backhoe operating procedures.
