Hydraulic Oil Supply
Operate lift function through one complete cycle before
checking oil level. Oil level should be at full mark or within
1.5 cm (0.5 in) below full mark on side of hydraulic tank
(all systems shut down, machine in stowed position); No
visible oil leaks on the ground.
Steer Cylinder
No rust, nicks, scratches or foreign material on piston rod;
no leakage.
Steer Linkage
No loose or missing parts; no visible damage.
Front Spindle Assemblies
No excessive wear; no damage; evidence of proper lubri-
cation.
Control Boxes (Platform and Ground)
Switches operable; no visible damage; placards secure
and legible; controller operable; no visible damage.
Batteries
Proper electrolyte level; cable connections tight; no visible
damage; no corrosion at battery cable connections.
Ensure batteries are fully charged.
Motor/Pump Unit and Valves
No leakage; units secure.
Platform Placards
No visible damage; placards secure and legible.
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 oil, fuel and 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.
Operators and Safety Manual
Ensure a copy of this manual is enclosed in the manual
storage box.
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
Perform functional checks in accordance with the Daily
Functional Check before attempting to operate the
machine.
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,
under no load, once the walk-around inspection is com-
plete, in an area free of overhead and ground level
obstructions. Perform pre-load functional check in accor-
dance with the following procedure:
1. Ensure batteries are fully charged.
2. Raise and lower platform several times. Check for
smooth elevation and lowering. Check for High
Drive cut-out as platform begins to raise. Check that
pothole protection system is deployed when plat-
form is raised and that actuating rollers are in con-
tact with the connecting bar.
