2.5 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,
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. From ground control, raise and lower platform sev-
eral times. Check for smooth elevation and lowering.
From the platform control station, check for High
Drive cut-out as platform begins to raise. Check that
pothole protection system is lowered when platform
is raised. Attempt to drive machine with platform
raised to the heights listed, per model, in Table 2-1,
High Drive Cut-Out and pothole protection system
blocked from lowering on one side then repeat for
the other side. Machine should not drive with plat-
form elevated unless pothole protection system is
fully lowered and locked. When pothole protection
system is fully lowered there should be approxi-
mately 3/4 in. of ground clearance.
3. Drive forward and reverse, check for proper opera-
tion.
4. Check that drive brake holds when machine is
driven up a hill, not to exceed 25% grade, and
stopped.
5. Steer left and right. Check for proper operation.
6. Check fluid level on hydraulic oil reservoir. Refer to
Figure 2-3., Lubrication Diagram.
7. Check to be sure that drive cannot be activated
while lifting.
2.6 TORQUE REQUIREMENTS
The Torque Chart, Figure 2-3., Torque Chart, consists of
standard torque values based on bolt diameter and grade,
also specifying dry and wet torque values in accordance
with recommended 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 ser-
vice personnel can be notified. The Service and Mainte-
nance Manual provides specific torque values and
periodic maintenance procedures with a listing of individ-
ual components. Utilizing this Torque Chart in conjunction
with the preventive maintenance procedures in the Ser-
vice and Maintenance Manual will enhance safety, reliabil-
ity and performance of the machine.
2.7 BATTERY CHARGING
At the end of the work day, the batteries should be
charged for the next day’s work. Position the Emergency
Stop switch to OFF. Prior to charging, be sure electrolyte
level is above battery plates. Connect the battery charger
to a properly grounded 110 Volt receptacle using a suit-
able extension cord. After charging, check the electrolyte
level of the batteries and adjust accordingly. Add distilled
water only to batteries. A fully charged battery will have a
specific gravity above 1.260 on a hydrometer.
WHEN ADDING DISTILLED WATER TO THE BATTERIES, A NON-
METALLIC CONTAINER AND/OR FUNNEL MUST BE USED. ADD
WATER ONLY TO LEVEL INDICATOR OR 3/8 INCH (0.95 CM)
ABOVE SEPARATORS.
NO OPEN FLAMES OR SMOKING WHEN CHARGING BATTERIES.
CHARGE BATTERIES ONLY IN A WELL VENTILATED AREA.
ENSURE THAT BATTERY ACID DOES NOT COME INTO CONTACT
WITH SKIN OR CLOTHING.
NOTE: Be sure to disconnect and store any extension cords
after charging batteries and before putting machine
into service.
To avoid electrolyte overflow, add distilled water to
batteries after charging.
