Operating the Machine
USING QUICK-COUPLER TYPE
ATTACHMENTS
GENERAL OPERATING TIPS
IMPORTANT: To avoid damaging machine cylinder(s),
do not strike ground with attachment or
operate with cylinders fully extended or
retracted.
Do not operate the attachment with the hydraulic
cylinder rods fully extended or fully retracted.
Do not strike the ground or other objects with the
attachment.
KEEPING HYDRAULIC SYSTEM CLEAN
IMPORTANT: To prevent damage to hydraulic
components, keep contamination from
entering hydraulic system.
Use wrench to loosen connectors when connecting and
disconnecting hydraulic lines to attachment.
While attaching or detaching attachments, the hydraulic
lines are open. Contamination can enter the hydraulic
system at this time, causing machine damage. If
attachments are changed frequently, there are more
opportunities for contamination to enter the hydraulic
system. To keep hydraulic oil contamination to a
minimum:
Clean connectors before disconnecting hydraulic lines.
Install caps and plugs on hydraulic lines as soon as
possible.
Change hydraulic return filter at half the normal interval
(250 hours).
Sample hydraulic oil every 500 hours. (See OILSCAN
PLUS in Periodic Maintenance chapter.) Follow
OILSCAN PLUS recommendations for oil change
interval, but never change the oil less frequently than
recommended for the machine.
