Section 4: Maintenance & Lubrication
Maintenance
Proper servicing and adjustment are key to the long life of
any attachment. With careful and systematic inspection,
you can avoid costly maintenance, time, and repair.
After using your Powered Rake for several hours, check
all bolts to be sure they are tight. Replace any worn,
damaged, or illegible safety labels by obtaining new
labels from your Kubota 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
attachment who have been properly trained in its safe
operation.
•
Check hitch fit-up frequently. An improper fit-up can cause
the attachment to come loose from the loader hitch plate
and fall.
•
Check hydraulic hoses and fittings frequently. Brush and
other debris can damage hoses and fittings causing the load
to release and fall.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service.
•
Do not alter attachment or replace parts on the attachment
with other brands. Other brands may not fit properly or
meet OEM specifications. They can weaken the integrity
and impair the safety, function, performance, and life of the
attachment. Replace parts only with genuine OEM parts.
Drive Chain Maintenance
The operator should check chain tightness after initial run
in and periodically thereafter to make sure that the drive
chain is tensioned correctly. If adjustment is needed refer
to
“Drive Chain Adjustment” on page 20.
IMPORTANT: If chaincase and/or sprocket shafts
are disassembled, it may be necessary to shim
between the chaincase and frame tube during
reassembly to properly realign the sprocket shafts.
Shim Pack
314-254A may be purchased from your
nearest Kubota dealer for this purpose.
