Maintenance
Proper servicing and adjustments are key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
Check all bolts and pins after using the unit for several
hours and on a regular basis thereafter to ensure they are
tight and secured.
Replace worn, damaged, or illegible safety labels by
obtaining new labels from your Land Pride dealer.
DANGER
!
To avoid serious injury or death:
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment supported
by concrete blocks or hydraulics. Concrete can break,
hydraulic lines can burst, and/or hydraulic controls can be
actuated even when power to hydraulics is off.
WARNING
!
To avoid serious injury or death:
•
Allow only persons to perform maintenance on this
implement who have been properly trained in its safe
operation.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service.
•
For safety reasons, each maintenance operation must be
performed with harrow lowered completely to the ground or
safely supported on blocks with tractor park brakes
engaged, engine shut off and ignition key removed.
•
Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
Replace parts only with genuine OEM parts.
