WHEN WORKING UNDER TRACKS
There is the danger of an accident of being caught under
the machine if the machine comes down.
Place supporting pillars or blocks under the crawler and
make sure that it is supported firmly.
ALWAYS RELEASE PRESSURE BEFORE
DISCONNECTING HYDRAULIC LINES
There is the danger of high pressure oil jetting out if a
piping or a hose is removed without releasing the internal
pressure of the hydraulic system. Start the work only
after completely releasing the internal pressure.
SUPPORTING THE VESSEL
If replacement or repair of couplings or hoses is made
with the vessel in the raised condition, there is the
possibility that the vessel drops down.
Be sure to support the vessel using the safety bar.
DO NOT WATCH THE CHECK VALVE WHEN
ADJUSTING TRACKS
• Track adjusting grease is under high pressure. Grease
coming out of the check valve under pressure can
penetrate the body causing injury or death.
• Watch the track or track adjustment cylinder to see if
the track is being loosened. Loosen the check valve
one turn only.
• Do not put your face, hand, foot, or body in front of the
check valve.
