2.4 DAILY WALK-AROUND INSPECTION
It is the operators responsibility to inspect the machine
before the start of each workday. It is recommended that
each operator inspect the machine before operation, even
if the machine has already been put into service under
another operator. This Daily Walk-Around Inspection is the
preferred method of inspection.
These checks are also to be performed after maintenance
has been performed on the machine.
In addition to the Daily Walk-Around Inspection, be sure to
include the following as part of the daily inspection:
1. Overall cleanliness.
Check all standing surfaces for oil, fuel and hydrau-
lic oil spillage and foreign objects. Ensure overall
cleanliness.
2. Placards.
Keep all information and operating placards clean
and unobstructed. Cover when spray painting or
shot blasting to protect legibility.
3. Operator’s and Safety Manual.
Ensure a copy of this manual and the ANSI A92.5-
1992 Responsibilities, are enclosed in the manual
storage box.
4. Machine Log.
Ensure a machine operating record or log is kept,
check to see that it is current and that no entries
have been left uncleared, leaving machine in an
unsafe condition for operation.
5. Start each day with a full fuel tank.
TO AVOID INJURY, DO NOT OPERATE A MACHINE UNTIL ALL
MALFUNCTIONS HAVE BEEN CORRECTED. USE OF A MALFUNC-
TIONING MACHINE IS A SAFETY VIOLATION.
TO AVOID POSSIBLE INJURY, BE SURE MACHINE POWER IS
"OFF" DURING WALK-AROUND INSPECTION.
NOTE: Check boom limit switches on upright for proper
operation and security, both visually and manually.
The lower switch cuts out drive speed when the
lower boom is above horizontal. The upper switch
cuts out drive speed when the upper boom is above
horizontal. Only creep drive speed will continue to
function.
6. Check platform footswitch for proper operation.
Switch must be released to start engine and
depressed to operate machine.
7. Check that drive brakes hold when machine is
driven up a grade not greater than specified on the
serial number placard and stopped.
NOTE: On new machines, those recently overhauled, or
after changing hydraulic oil, operate all systems a
minimum of two complete cycles and recheck oil
level in reservoir.
8. Assure that all items requiring lubrication are ser-
viced. Refer to Figure 2-5., Lubrication Diagram for
specific requirements.
