13. Platform Assembly- Secure to mast; no loose
or missing parts, no visible damage. Control
and power cables, no visible damage; cables
properly tensioned and seated in control cable
sheaves; control cable sheaves not damaged
and rotate freely.
.. 14. Platform Controls - Up/Down and Function
Enable buttons properly secured, no loose or
missing parts, no visible damage. Placards
secure and legible, emergency shut-off button
set for operation. Control markings legible; Op-
erators manual enclosed in manual storage
tube.
In addition to the Daily Walk-Around Inspection, be
sure to include the following as part of the daily
inspection:
• Batteries Charged (DC Models)
Start each day with fully charged batteries. (See
Section 2-7. "Battery Charging")
• Overall Cleanliness
Keep oil, grease, water, etc. wiped from standing
surfaces and hand holds.
• Placards
Keep all information and operating placards clean
and unobstructed. Cover areas where placards
are present when using the machine for spraying
paint or any material which could cover these
surfaces and reduce legibility.
• Operators, Safety, and Maintenance
Manual
Ensure a copy of this manual is enclosed in the
manual storage box.
• Lubrication
For those parts pointed out in the Walk-Around
Inspection requiring lubrication, refer to the Lubri-
cation Chart, Figure 7-2., Section 7, for specific
time interval requirements.
2-5. DAILY FUNCTIONAL CHECK
A
WARNING
TO AVOID INJURY DO NOT OPERATE A MACHINE
UNTIL ALL MALFUNCTIONS HAVE BEEN COR-
RECTED. USE OF A MALFUNCTIONING MACHINE
IS A SAFETY VIOLATION.
Once the walk-around inspection is complete, a func-
tional check of all systems should be performed in an
area free of overhead and ground level obstructions.
Perform a functional check in accordance with the
following procedures:
1. Set-up machine for operation, according to
instructions in Section 4-3, "Machine Set-Up &
Operation", i.e .. install outriggers, level ma-
chine, make sure all wheels are off ground, etc.
2.
Enter platform, raise and lower platform two (2)
to three (3) feet several times. Check for
smooth elevation and lowering of platform.
3. With platform completely lowered, check hy-
draulic oil level in reservoir at ground control
station. Oil level should show full on the dip-
stick. If necessary, add hydraulic fluid to proper
level. NEVER USE HYDRAULIC BRAKE
FLUID, refer to the Lubrication Chart, Figure
7-2, for specific requirements.
2-6. TORQUE REQUIREMENTS
The Torque Chart, Figure 7-1, consists of standard
torque values based on bolt diameter and grade, it
also specifies dry and wet torque values in accord-
ance with recommended shop practices. This chart is
provided as an aid to the user/operator in the event
he/she notices a condition that requires prompt atten-
tion during the walk-around inspection or during op-
eration until the proper service personnel can be
notified. Utilizing this Torque Chart in conjunction
with the preventive maintenance section in Section 8,
will enhance the safety, reliability and performance of
the machine.
