General; Hydraulic System Safety; Troubleshooting Safety - JLG T350 Troubleshooting Manual

SECTION B.
B.1 GENERAL
This section contains the general safety precautions
which must be observed during troubleshooting of the
aerial platform. It is of utmost importance that mainte-
nance personnel pay strict attention to these warnings
and precautions to avoid possible injury to themselves or
others, or damage to the equipment. A maintenance pro-
gram must be followed to ensure that the machine is safe
to operate.
MODIFICATION OF THE MACHINE WITHOUT CERTIFICATION BY
A RESPONSIBLE AUTHORITY THAT THE MACHINE IS AT LEAST
AS SAFE AS ORIGINALLY MANUFACTURED, IS A SAFETY VIOLA-
TION.
The specific precautions to be observed during trouble-
shooting are inserted at the appropriate point in the man-
ual. These precautions are, for the most part, those that
apply when servicing hydraulic and larger machine com-
ponent parts.
Your safety, and that of others, is the first consideration
when engaging in the troubleshooting of equipment.
Always be conscious of weight. Never attempt to move
heavy parts without the aid of a mechanical device. Do not
allow heavy objects to rest in an unstable position. When
raising a portion of the equipment, ensure that adequate
support is provided.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CON-
TROL OVER TROUBLESHOOTING, SAFETY IN THIS AREA IS THE
RESPONSIBILITY OF THE OWNER/OPERATOR.
B.2 HYDRAULIC SYSTEM SAFETY
It should be noted that the machines hydraulic systems
operate at extremely high potentially dangerous pres-
sures. Every effort should be made to relieve any system
pressure prior to disconnecting or removing any portion of
the system.
