WARNING
DO NOT make repairs or adjustments unless
you have been properly trained and authorized
to do so.
Improper repairs and adjustments
can create dangerous operating conditions.
DO NOT operate a lift truck that needs re-
pairs.
Report the need for repairs to your
supervisor immediately.
If repair is neces-
sary, turn the key switch to the OFF position,
disconnect the battery, and attach a DO NOT
OPERATE tag to the control handle.
Disconnect the battery before opening the
drive unit compartment cover or inspecting or
repairing the electrical system. If a tool causes
a short circuit, the high current flow from the
battery can cause personal injury or property
damage.
The capacitor in the transistor controller can
hold an electrical charge after the battery is
disconnected. To prevent electrical shock and
personal injury, discharge the capacitor before
inspecting or repairing any component in the
drive unit compartment. See Special Precau-
tions in this section.
All checks, adjustments, and repairs in the drive
unit compartment are done with the compartment
cover removed. Remove the drive unit compartment
cover for access to the electrical components and
discharge the capacitor. See the section Periodic
Maintenance 8000 SRM 1368. Replace the covers
when service has been completed.
