MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS 9-1 Operating Conditions Precautions for Maintenance Muddy Soil, Rainy or Snowy Weather Before Operation: Check the tightness of plug and all drain cocks. After Operation: Clean the machine and check for cracks, damaged, loose or missing bolts and nuts. Lubricate all necessary parts without delay. Near the Ocean Before Operation: Check tightness of plugs and all drain cocks. After Operation: Thoroughly clean the machine with fresh water to wash off salt. Service elec- trical equipment often to prevent corrosion. Dusty Atmosphere Air Cleaner:
Clean the element regularly at shorter service intervals. Radiator: Clean the oil cooler screen to prevent clogging of the radiator core. Fuel System: Clean the filter element and strainer regularly at shorter service intervals. Electrical Equipment: Clean them regularly, in particular, the commutator surface of the alternator and starter. Rocky Ground Tracks: Carefully operate while checking for cracks, damage and loose bolts and nuts. Loosen the tracks a little more than usual. Front Attachment: Standard attachment may be damaged when digging rocky ground. Rein- force the bucket before using it, or use a heavy duty bucket. Freezing Weather Fuel:
Use high quality fuel suitable for low temperature. Lubricant: Use high quality low viscosity hydraulic oil and engine oil. Engine Coolant: Be sure to use antifreeze. Battery: Fully charge the batteries regularly at shorter service intervals. If not fully charged, electrolyte may freeze. Tracks: Keep the track clean. Park the machine on a hard surface to prevent the tracks from freezing to the ground. Falling Stones Cab: Provide a cab guard to protect the machine from falling stones when neces- sary.
