14. When working on hydraulic system, be sure the battery is discon-
nected, upright is in the fully-lowered position, and hydraulic
pressure is relieved in hoses and tubing.

Always put blocks under the carriage and upright rails
when necessary to work with upright in an elevated
position.

instruction plates, tags, or decals must be maintained in legible
condition.

and connections must be maintained in conformance with good
practice. Special attention must be paid to the condition of
electrical insulation.
17. To avoid injury to personnel or damage to the equipment, consult
the manufacturer's procedures in replacing contacts on any
battery connection.
18. Industrial trucks must be kept in a clean condition to minimize fire
hazards and help in detection of loose or defective parts.
19. Modifications and additions that affect capacity and safe truck
operation must not be done without the manufacturer's prior
written approval. Capacity, operation, and maintenance instruc-
tion plates, tags, or decals must be changed accordingly.
20. Care must be taken to assure that all replacement parts, including
tires, are interchangeable with the original parts and of a quality at
least equal to that provided in the original equipment. Parts,
including tires, are to be installed per the manufacturer's proce-
dures. Always use genuine CLARK or CLARK-approved parts.
