Maintenance
Proper servicing and adjustments are key to the long life
of any attachment. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
Check all bolts after using the unit for several hours to be
sure they are tight. Replace any worn, damaged, or
illegible safety labels by obtaining new labels from your
Kubota dealer.
WARNING
!
To avoid serious injury or death:
•
Do not alter Kubota equipment or replace parts with other
brands. Doing so can cause equipment to perform
improperly and may lead to breakage that can cause bodily
injury or death. Replace parts only with genuine Kubota
parts.
•
Never work under the Skid Steer Grader without blocking it
up properly first. The grader can fall causing bodily injury
or death. Always use solid blocks, never concrete blocks.
•
Frequently check all hardware to make certain it is tight.
Operating attachment with loose pins, bolts, or nuts can
cause attachment to not perform properly and may result in
a serious breakdown that can cause bodily injury or death.
•
Backup alarm must be in good working order to warn
Long-Term Storage
1.
Scrape off compacted dirt and then wash the grader
thoroughly to remove any dirt and grease that may
have accumulated on the grader.
2.
Repaint parts where paint is worn or scratched to
prevent rust. A coating of oil may be applied to the
lower unpainted frame area and blades to minimize
oxidation.
3.
Check grader blades and bolts for wear and replace
if necessary.
4.
Inspect for loose, damaged or worn parts and adjust
or replace as needed.
5.
Repaint parts where paint is worn or scratched to
prevent rust. Ask your Kubota dealer for aerosol
touch-up paint. Paint is also available in touch-up
quarts and gallon sizes.
6.
Replace all damaged or missing decals.
7.
Store grader on a level surface in a clean, dry place.
Inside storage will reduce maintenance and make for
a longer grader life.
