Torque Requirements
The Torque Chart (Figure 2-4.) consists of standard torque
values based on bolt diameter and grade, also specifying
dry and wet torque values in accordance with recom-
mended shop practices. This chart is provided as an aid
to the operator in the event he/she notices a condition that
requires prompt attention during the walk-around inspec-
tion 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 components. Utiliz-
ing this Torque Chart in conjunction with the preventive
maintenance section in the Service and Maintenance
manual will enhance safety, reliability, and performance of
the machine.
2.4 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 is 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.
