Replacing The Fuel System Water Separator Filter Element
1. Thoroughly clean the water separator and the area around it.2. Drain all the water from the separator, as described above, and then close the vent valve and drain valve.3. Remove the clamp and pull the filter element off the base.4. Use a clean cloth to clean the three sealing areas.5. Install the new element on the base so the pin fits in the outlet passage at the bottom of the element.6. Install the clamp so the lock tab fits into the slot on the bottom of the base, and the upper lock tab fits into the slot on top of the base. THE CLAMP MUST BE INSTALLED WITH THE FINGER TAB ON TOP AS SHOWN. MAKE SURE THE CLAMP HOLDS THE FILTER ELEMENT TIGHTLY AGAINST THE BASE. USE THE PRIMING PUMP, IF NECESSARY, TO PRIME THE FUEL SYSTEM FOR RESTARTING.Checking Hydraulic Oil Level
The hydraulic oil tank is equipped with a sight gauge for easy checking of the hydraulic oil level. The hydraulic oil level should be maintained halfway up the sight gauge, or higher. If the hydraulic oil level is low, use the replenishing hand pump to pump oil from the replenishing tank into the main hydraulic oil tank. Refill the replenishing tank with new water-free hydraulic oil conforming to the specification on page 4-1. Do not overfill either tank, allow for expansion of the oil and changes in the main tank level as the cylinders are operated.Checking The Hydraulic Oil Filter Indicator
Push the test button and be sure the indicator light comes on. If the light does not come on, check the fuse and the light bulb. DO NOT OPERATE THE MACHINE IF THE INDICATOR WILL NOT FUNCTION.Checking Hydraulic Oil Cooler And Radiator
Since the cooling air flows through the oil cooler and then through the radiator, any obstructions to air flow through either will also obstruct the air flow through the other. Any rags, paper, mud, dust, cuttings, bugs, etc. that may obstruct the air flow must be removed.Checking Cutter Bits, Bit Holders And Flighting
NEVER OPEN THE CUTTER DOORS WITH THE ENGINE RUNNING OR WITH THE WHEELS TURNED. IF THE JOG SWITCH WILL NOT TURN THE CUTTER, SEE PAGE 4-46. The cutter bits should be checked for excessive wear and replaced anytime the distance from the holders to the tip of the bits (normal wear) or to the end of the supporting metal (carbide tip exposed) is 1 1/4inches or less.At the same time the bits are checked, also check the cutter flighting and bit holders for breaks and cracks. Replace as necessary.Replacing A Cutter Bit
Place the fork of the bit puller under the shoulder of the bit and then slide the weight sharply against the retainer to break the bit loose. Insert a new bit into the holder and hammer it into place so that the keeper spring is engaged with the holder.Replacing A Damaged Bit Holder Or Flighting Section
1. Unbolt
