Troubleshooting

3.0 Introduction
Table 3-1 provides a logical sequence of tests that are
designed to isolate problems with the Snorkel Lift. This
table includes a list of probable causes and remedies.
When troubleshooting, ensure that the work
platform is resting on a firm, level surface.
When performing any service which re-
quires the Platform to be raised, ensure that
all four (4) outriggers are properly installed.
Unplug the machine or disconnect the bat-
tery when replacing or testing the continuity
of any electrical component.
GENERAL PROCEDURE
Troubleshooting should be carried out in two steps. First,
thoroughly study both hydraulic and electric schematics to
determine possible causes. Loose terminal connections and
short circuits are always a potential cause when trouble-
shooting. Second, check suspect components electrically,
hydraulically and mechanically to determine if they are at
fault. Refer to Tables 4-1 and 4-2 for Reference Designa-
tions used in Table 3-1.
