STORAGE
Your rotary cutter represents an investment from which you should get the greatest possible benefit. Therefore,
when the season is over, the cutter should be thoroughly checked and prepared for storage so that a minimum
amount of work will be required to put it back into operation for the next season. The following are suggested
storage procedures:
1. Thoroughly clean the cutter.
2. Lubricate the cutter as covered in Maintenance Section.
3. Tighten all bolts and pins to the recommended torque.
4. Check the cutter for worn or damaged parts. Make replacements immediately.
5. Store the cutter in a clean, dry place with the cutter housing resting on blocks.
6. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the cutter.
PROPER TORQUE FOR FASTENERS
The torque chart (Figure 7) lists the correct tightening torque for fasteners. When bolts are to be tightened or
replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque
values are assigned in manual text.
RECOMMENDED TORQUE IN FOOT POUNDS (NEWTON-METERS) UNLESS OTHERWISE STATED IN
THE MANUAL
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine oil.
They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are used.
This applies to both UNF fine and UNC coarse threads.
