SECTION 2 - PREPARATION AND INSPECTION
3120860 – JLG Lift – 2-9
2.5 DAILY FUNCTIONAL CHECK.
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.
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.
TO AVOID A COLLISION AND INJURY IF PLATFORM DOES NOT
STOP WHEN A CONTROL SWITCH OR LEVER IS RELEASED,
REMOVE FOOT FROM FOOTSWITCH OR USE EMERGENCY STOP
TO STOP MACHINE.
1. Check boom limit switches. Raise and lower the
Lower Boom. Check for smooth operation. Check
Boom Upright tilting. (See Figure 4-2. Upright posi-
tioning Models 40e and 45e).
NOTE: Perform checks from ground controls first, then from
platform controls.
2. Raise, extend, retract, and lower the Upper Boom.
Check for smooth operation.
3. On models (40/n40/45 electric), if tower boom does
not rest on stop with machine in the stowed position,
this indicates upright is out of plumb.(Ref. 2-20 of
service manual 3120861, for Boom Synchronizing
procedure)
4. On models (35/n35/40/n40/45 electric), telescope
boom IN and OUT several cycles at various degrees
of elevation lengths. Check for smooth telescope
operation.
5. Swing turntable to LEFT and RIGHT a minimum of
45 degrees. Check for smooth motion.
6. With the aid of an assistant to monitor the CHASSIS
OUT OF LEVEL indicator light on the platform con-
sole, manually activate the indicator light by com-
pressing one of the three tilt indicator mounting
springs. If the light does not illuminate, shut down
machine and contact a qualified service technician
before continuing operation.
7. Check that platform self-leveling system functions
properly during raising and lowering of boom.
8. On models (35/n35/40/n40/45 electric), check rota-
tor for smooth operation and assure platform will
rotate 75 degrees in both directions from centerline
of boom.
9. Drive forward and reverse; check for proper opera-
tion.
10. Steer left and right; check for proper operation.
11. Footswitch.
FOOTSWITCH MUST BE ADJUSTED SO THAT FUNCTIONS WILL
OPERATE WHEN PEDAL IS APPROXIMATELY AT ITS CENTER OF
TRAVEL. IF SWITCH OPERATES WITHIN LAST 1/4" (6 MM) OF
TRAVEL, TOP OR BOTTOM, IT SHOULD BE ADJUSTED.
FOOTSWITCH MUST BE DEPRESSED PRIOR TO ACTIVATING ANY
FUNCTION CONTROL, OTHERWISE THE FUNCTION WILL NOT
WORK.
With footswitch depressed, operate LIFT and hold
control. Remove foot from footswitch, motion should
stop. If it does not, shut down machine and contact
a qualified service technician.
12. Holding the GROUND/PLATFORM SELECT switch
to GROUND. Platform controls should not operate.
13. Place GROUND/PLATFORM SELECT switch to OFF.
Platform/Ground controls should not operate.
2.6 TORQUE REQUIREMENTS.
The Torque Chart (Figure 2-5) consists of standard torque
values based on bolt diameter and grade, also specifying
dry, wet and loctite torque values in accordance with rec-
ommended 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
inspection or during operation, until the proper service
personnel can be notified. The Service and Maintenance
section provides specific torque values and periodic main-
tenance procedures with a listing of individual compo-
nents. Utilizing this torque chart in conjunction with
preventive maintenance section will enhance safety, reli-
ability, and performance of the machine.
