SAFETY
DO NOT OVERLOAD TO CYLINDER.
Do not forcefully conduct digging operation
beyond the capacity, which may overload any
cylinder and open its relief valves.
This causes damage to the hydraulic system
and machine.
NEVER CONDUCT DIGGING OPERATION
WITH FALLING FORCE OF MACHINE.
Do not raise off the rear of the machine from
the ground and drop it down for digging up.
This will cause excessive shock and damage
to the machine.
MEASURE DEPTH OF WATER AND
CHECK CONDITIONS OF RIVERBED
BEFORE FORDING.
Before fording, measure the depth of water
and check the riverbed for holes, bumps, and
any dangerous condition by following the
next:
• Measure the depth of water first.
• Stop the machine and swing the bucket
under the water to detect any bump or
obstacle.
• Lower the bucket to measure the depth of
water and detect holes occasionally.
OBSERVE THE ALLOWABLE WATER
DEPTH.
Allowable depth of water is limited up to the
center of the upper rollers.
Be sure to lubricate long-soaked parts until
old grease comes out of the bearings.
