DAILY CHECKING THE LOADER
WARNING
To avoid personal injury or death:
• When removing the engine side covers, be
careful not to touch hot loader cylinders. Allow
all surfaces to cool before performing
maintenance.
• Before servicing the loader or the tractor, be
sure to place the boom of the loader in contact
with the ground. When raising the boom of the
loader during service or maintenance, support
the boom as shown in the figure.
1. Before daily operation, visually check to see if the
hardware and their bolts and nuts are tight.
Tighten the hardware of the loader to torque values
as specified in the Re-tightening of hardwares of
the loader on page 34 and GENERAL TORQUE
SPECIFICATION on page 52.
2. With the engine off and the bucket on the ground,
inspect all hoses for cuts or wear. Check for signs
of leaks and make sure all fittings are tight.
WARNING
To avoid personal injury or death:
• Escaping hydraulic fluid under pressure can
produce sufficient force to penetrate skin,
causing serious personal injury.
Before disconnecting lines, be sure to
relieve all pressure.
• Before applying pressure to the loader
system, be sure that all connections are
tight and that lines, tubes, and hoses are not
damaged.
• Fluid escaping from a pin hole can be
almost invisible. Use a piece of cardboard or
wood to search for suspected leaks. Do not
use hands to search for suspected leaks.
• If you are injured by escaping fluid, see a
doctor at once. Serious infection or allergic
reaction will develop if proper medical
treatment is not administered immediately.
