2.4 DAILY WALK-AROUND INSPECTION
It is the users responsibility to inspect the machine before
the start of each workday. It is recommended that each
user inspect the machine before operation, even if the
machine has already been put into service under another
user. 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:
Overall Cleanliness
Check all standing surfaces for hydraulic oil spillage and
foreign objects. Ensure overall cleanliness.
Placards
Keep all information and operating placards clean and
unobstructed. Cover when spray painting or shot blasting
to protect legibility. Uncover prior to machine operation
Operators and Safety and Service and
Maintenance Manual
Ensure that a copy of this manual is enclosed in the man-
ual storage holder.
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.
Daily Lubrication
For those items pointed out in the Daily Walk - Around
Inspection requiring daily lubrication, refer to the Lubrica-
tion Chart for specific requirements.
2.5 DAILY FUNCTIONAL CHECK
TO AVOID INJURY DO NOT OPERATE A MACHINE UNTIL ALL
MALFUNCTIONS HAVE BEEN CORRECTED. USE OF A MALFUNC-
TIONING MACHINE IS A SAFETY VIOLATION.
A functional check of all systems should be performed,
once the walk-around inspection is complete, in an area
free of overhead and ground level obstructions. First,
using the ground controls, check all functions controlled
by the ground controls. Next, using the platform controls,
check all functions controlled by the platform controls.
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.
1. Check Enable Switch for proper operation. Switch
must be pressed before activating any functions.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY
CONTROL LEVERS OR TOGGLE SWITCHES CONTROLLING
PLATFORM MOVEMENTS DO NOT RETURN TO THE OFF POSI-
TION WHEN RELEASED.
2. Raise and lower platform several times. Check for
smooth elevation and lowering. Check that High
Drive cut-out as platform begins to raise.
NOTE: Perform checks from ground controls first, then from
platform controls.
3. Drive forward and reverse, check for proper opera-
tion.
4. Check that drive brakes hold when machine is
driven up a hill, not to exceed rated gradeability, and
stopped.
5. Steer left and right. Check for proper operation.
6. Check hydraulic oil reservoir level marks. Refer to
Lubrication Chart.
7. Holding the Ground/Platform select switch to
Ground. Platform controls should not operate.
8. Place Ground/Platform select switch to off. Platform/
Ground controls should not operate.
2.6 TORQUE REQUIREMENTS
The Torque Chart consists of standard torque values
based on bolt diameter and grade, also specifying dry,
wet and loctite torque values in accordance with recom-
mended shop practices. This chart is provided as an aid
