TL33 Work Platform 5-1
5.0 Introduction
Table 5-1 provides a logical sequence of tests that are
designed to isolate problems with TL33 machines.
This table includes a list of probable causes and remedies.
When troubleshooting, ensure that the
work platform is resting on a form, level
surface.
When performing any service on or in the
elevating assembly area, which requires
the platform to be raised, the elevating
assembly must be securely supported by
overhead cranes of suitable capacity.
Disconnect the batteries ground cable
when replacing or testing the continuity of
any electrical component.
GENERAL PROCEDURE
Trouble shooting should be carried out in two steps.
First, thoroughly study both the 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 6-1 and 6-2
