BOLT TORQUE Mounting bolts and hardware Before operating the Disc Sealer for the first time, check to be sure that all hardware is tight. Check all hardware again after approximately 50 hours of operation and at the beginning of each season. All hardware used on the Disc Sealer is Grade 5 unless otherwise noted. Grade 5 cap screws are marked with three radial lines on the head. If hardware must be replaced, be sure to replace it with hardware of equal size, strength and thread type.
ASSEMBLY “Barn Yard Setting” – set the sealer blade to 2” closer to the bottom of the knife than the depth that the knife will be used at. Example: knife at 6” depth, set the blades to 4” above the bottom of the knife. Adjust the blade pitch as needed to cover the knife track with soil. Tighten all hardware to the recommended amount of torque unless otherwise stated.
ASSEMBLY 1. When assembling blade, bearing assembly and hubcap, be sure to align the grease fitting, hole in the blade and slot in hub cap to assure proper greasing of blade assembly.

Follow ALL the operating, maintenance and safety information in the equipment operator manual. Clear the area of bystanders, especially small children, when performing any maintenance or adjustments. Keep work area clean and dry. Use adequate lighting for the job. Use only tools, jacks and hoists of sufficient capacity for the job.
MAINTENANCE NOTE: Be certain to align the grease fitting with the slot in the wheel and the hubcap so that the grease can flow freely.

Lower machine to ground or sufficiently lock or block raised machine before servicing. If machine is connected to tractor, engage parking brake and place transmission in "PARK", shut off engine and remove key. If machine is detached from tractor, block wheels and use shop stands to prevent movement.
MAINTENANCE Lubrication Symbols Lubricate with grease at hourly interval indicated on symbol. Lubrication Intervals IMPORTANT: The recommended service intervals are based on normal conditions; severe or unusual conditions may require more frequent lubrication. Perform each lubrication and service procedure at the beginning and end of each season. Clean grease fittings before using grease gun, to avoid injecting dirt and grit into the bearing. Replace any lost or broken fittings immediately.
MAINTENANCE Storing the Equipment Store the machine in an area away from human activity Store machine in RAISED position. Install service locks on all wheel cylinders. At the end of the season, the machine should be thoroughly inspected and prepared for storage. Repair or replace any worn or damaged components to prevent down time at the start of the next season.
