SAFETY
ALWAYS RELEASE PRESSURE BEFORE
DISASSEMBLING HYDRAULIC LINES.
Before disconnecting hydraulic fluid lines
on a hydraulic machine, be sure you.
• Place boom on the ground or have it
supported.
• Shut off engine.
• Always release any pressurized air on
hydraulic tank.
• Move control levers and pedals repeatedly
through their operating positions to relieve
pressures.
PRESSURIZED HYDRAULIC FLUID CAN
PENETRATE THE SKIN AND CAUSE
SERIOUS INJURY OR DEATH.
Therefore, be sure all connection are tight
and that lines, pipes, and hoses are in good
condition before starting the engine.
Fluid escaping from a small hole can be
almost invisible. Use a piece of cardboard or
wood, instead of your hands, to search for
suspected leaks.
If you are struck by escaping hydraulic fluid
under pressure, serious reactions can occur if
proper medical treatment is not administered
immediately. .
NEVER WATCH THE RELIEF VALVE
WHEN ADJUSTING TRACKS.
NEVER watch the relief valve when servicing
the tracks. Position yourself not to be
splashed with grease. Grease used to adjust
the tracks is highly pressurized and can
cause serious injury or death.
Carefully read and understand the maintenance
procedure for track adjustment.
