Platform
1.
Check platform and control console for damage,
loose or missing parts, and security.
2.
\Check control switches and levers for damage,
loose or missing parts and security. Assure that all
levers function properly.
3.
Check control switches, levers and electrical con-
nections for tightness and evidence of corrosion,
and wiring for defects and chafing damage. Assure
that all switches function properly.
4.
Check access gate hinges and latch for proper
operation, damage and security.
5.
Check platform rotator mechanism for proper opera-
tion, damage, security. Check hydraulic lines for
leakage, damage and security.
NOTE: Check all DANGER, WARNING, CAUTION and
INSTRUCTION placards for legibility and security on
the entire machine.
Torque Requirements
The Torque Chart (See Figure 2-6.) consists of standard
torque values based on bolt diameter and grade, also
specifying dry and wet torque values in accordance with
recommended shop practices. This chart is provided as
an aid to the operator in the event he/she notices a condi-
tion that requires prompt attention during the walk-around
inspection or during operation, until the proper service
personnel can be notified. The Service and Maintenance
manual provides specific torque values and periodic
maintenance procedures with a listing of individual com-
ponents. Utilizing this Torque Chart in conjunction with the
preventive maintenance section in the Service and Mainte-
nance manual will enhance safety, reliability, and perfor-
mance of the machine.

DAILY WALK-AROUND INSPECTION
It is the operator’s 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. (See Figure 2-2.)
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 horizontal limit switch for proper opera-
tion and security, both visually and manually. Switch
must shut down high engine and high drive speed
when boom is raised above horizontal:
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 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 Table 2-1, Lubrication Chart, for spe-
cific requirements.
