Section 5: Maintenance & Lubrication
Maintenance
Proper servicing and adjustment is the key to the long life
of any implement. 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
Land Pride dealer. Add grease to the zerks per
Lubrication Schedule on page 15.
The parts on your Retractable Box Scraper have been
specially designed and should only be replaced with
genuine Land Pride parts. Do not alter the scraper in a
way which will adversely affect its performance.
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:
•
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than
hands when searching for leaks. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service. Serious breakdowns can result in injury
•
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.
Tractor Maintenance
One of the most important things you can do to prevent
hydraulic system problems is ensure that your tractor's
reservoir remains free of dirt and contamination.
Use a clean cloth to wipe hose ends before attaching
them to your tractor. Replace your tractor’s hydraulic filter
element at the prescribed intervals. These simple
maintenances will go a long way to prevent occurrence of
control valve and hydraulic cylinder problems.
