Servicing the Foam Precleaner

Wash the foam precleaner every 25 hours of operation. Wash more often when operating under extremely dusty conditions. Replace the precleaner if torn or otherwise damaged.

Referring to Figure 56, wash the precleaner as follows:

•Remove the knob and lift off the air cleaner cover and the washer.

•Remove the foam precleaner by carefully slipping it up off the paper element.

•Wash the precleaner in warm water with detergent. Rinse the precleaner thoroughly to remove all traces of the detergent. Squeeze out (do not wring) excess water in a dry cloth. Allow the precleaner to air dry.

•Carefully slip the precleaner fully onto the paper element.

•Reinstall the air cleaner cover, washer, and knob.

IMPORTANT: Do not apply oil to the foam precleaner element.

SERVICING THE PAPER ELEMENT

Replace the paper air cleaner element every 300 hours or yearly, whichever comes first. Replace the element more often if operating the tractor under extremely dusty conditions. Refer to Figure 56.

•Remove the knob and lift off the air cleaner cover and the washer.

•Remove the wing nut and lift out the paper air cleaner element.

•Remove the foam precleaner by carefully slipping it off the paper element.

•Check the paper element for excessive dirt, paper tears, or damage to the seal on the bot- tom of the element. Replace a dirty or damaged paper element. Do not use pressurized air to clean the paper element.

•When servicing the air cleaner, also inspect the air cleaner base and the base seal for any type of damage. Replace if damaged.

•Slip the precleaner fully onto the paper ele- ment and reinstall the paper element onto the air cleaner base. Secure with the wing nut.

•Reinstall the air cleaner cover, washer, and knob.

IMPORTANT: Properly cleaned and installed air cleaner elements significantly contribute to prolonging engine life.

SERVICING THE SPARK PLUGS

WARNING: To avoid possible injury, be sure the engine is off and has cooled before making any adjustments or repairs.

Check the spark plugs after every 100 hours of operation. Replace with new plugs if necessary. See your authorized dealer for the correct replacement plugs.

•Disconnect the spark plug wires and remove all dirt from around the spark plug before removing.

•Use a spark plug wrench to remove the spark plugs.

•Clean carbon deposits from the electrodes using a soft wire brush.

•Inspect for cracked porcelain or other wear and damage. Replace with a new spark plug if necessary.

•Check the gap of the spark plugs. The gap must be .030 inch. Reset if necessary,

•Reinstall the spark plugs in the engine and torque to 18 ft-lbs. Connect the spark plug wires.

CHANGING THE FUEL FILTER

WARNING: Do not replace the fuel filter when tractor is hot. Allow the tractor to cool before separating the fuel lines.

The tractor is equipped with an in-line fuel filter. The fuel filter can be accessed from underneath the tractor along the left side of the tractor frame, just forward of the fuel tank.

The fuel filter cannot be disassembled. Conse- quently you must visually inspect the filter periodically. Inspect for a build-up of residue inside the filter body, and for a dirty element which can be indicated by discoloration. Replace the fuel filter when dirty.
