Hydraulic Oil Supply
Check the hydraulic oil level at the hydraulic fluid reservoir
through the access hole on the side of the ground control
panel. Maintain an oil level to the "Fill to Line" indicator on
the side of the reservoir.
If fluid level is low, see Service Manual, Section 1 - Specifi-
cations; Sub-Section 1.5 “Lubrication”, "Hydraulic Oil” for
recommended oil specification use in machine.

2.4 DAILY WALK-AROUND INSPECTION
It is the user/operator’s responsibility to inspect the
machine before the start of each workday. It is recom-
mended that each user/operator inspect the machine
before operation, even if the machine has already been
put into service under another user/operator. This Daily
Walk-Around Inspection is the preferred method of inspec-
tion.
General
Begin the “Walk-Around Inspection” (See Table 2-1.) at
item 1 listed following. Continue around machine check-
ing each item in sequence for the conditions listed in the
“Walk-Around Inspection Check list”.
TO AVOID INJURY DO NOT OPERATE MACHINE UNTIL ALL MAL-
FUNCTIONS 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: Do not overlook visual inspection of chassis under-
side. Checking this area often results in discovery of
conditions which could cause extensive machine
damage.
1. Wheels and Casters - Properly secured, wheels
and casters turn freely and are properly lubricated.
Check for any visible damage.
2. Base Frame - No visible damage; components
properly secured, no loose wires dangling below
base; bubble level in place and functioning properly.
3. Tilt Back Assembly - (36EL/41EL Models Only)
Properly secured; no visible damage; no parts miss-
ing i.e.. safety pins, gas spring cylinders, caster
wheels, etc.
4. Battery/Battery Charger Installation - (DC
Machines) Proper battery electrolyte level, cables
secure, no damage or corrosion. Battery box pivots
freely when machine is tilted for transporting (36EL/
41EL Models Only).
5. Outrigger Interlock Indicator LED’s - Properly
secured, no visible damage.
6. Outrigger Sockets - Properly secured to frame, no
visible damage (cracks, distortion, etc.). Outrigger
lock/release pins in place and secure, no visible
damage. Outrigger interlock contacts (inside outrig-
ger sockets) secure and clean.

tortion, etc..), outrigger interlock contacts properly
installed and clean. Leveling jacks secure, lubri-
cated and functioning properly.
8. Motor/Pump/Reservoir Unit - All properly secured,
no visible damage, no evidence of hydraulic leaks.
Check that hydraulic reservoir fluid level is filled to
the "Fill to Line" mark on the side of the reservoir.
9. Manual Descent Control Valve - Properly secured,
no loose or missing parts, no visible damage.
10. Ground Controls - Key switch operable, no visible
damage; placards secure and legible; emergency
stop switch, no visible damage and properly set for
operation.
11. Mast Installation - Mast sections properly secured,
no visible damage to mast sections, no loose or
missing parts, slide pads properly secured. Mast
