(13)Disconnect battery and discharge any capacitors
(electric trucks) before starting to work on truck.
Hang "Do not Operate" tag in the Operator's Com-
partment.
(14)Repairs, which require welding, should be per-
formed only with the benefit of the appropriate ref-
erence information and by personnel adequately
trained and knowledgeable in welding proce-
dures. Determine type of metal being welded and
select correct welding procedure and electrodes,
rods or wire to provide a weld metal strength
equivalent at least to that of parent metal.
(15)Do not damage wiring during removal operations.
Reinstall the wiring so it is not damaged nor will it
be damaged in operation by contacting sharp cor-
ners, or by rubbing against some object or hot
surface. Place wiring away from oil pipe.
(16)Be sure all protective devices including guards
and shields are properly installed and functioning
correctly before starting a repair. If a guard or
shield must be removed to perform the repair
work, use extra caution.
(17)Always support the mast and carriage to keep
carriage or attachments raised when maintenance
or repair work is performed, which requires the
mast in the raised position.
(18)Loose or damaged fuel, lubricant and hydraulic
lines, tubes and hoses could cause fires. Do not
bend or strike high pressure lines or install ones
which have been bent or damaged. Inspect lines,
tubes and hoses carefully. Do not check for leaks
with your hands. Pin hole (very small) leaks could
result in a high velocity oil stream that will be invis-
ible close to the hose. This oil could penetrate the
skin and cause personal injury. Use cardboard or
paper to locate pin hole leaks.
(19)Tighten connections to the correct torque. Make
sure that all heat shields, clamps and guards are
installed correctly to avoid excessive heat, vibra-
tion or rubbing against other parts during opera-
tion. Shields that protect against oil spray onto hot
exhaust components in event of a line, tube or
seal failure, must be installed correctly.

(20)Relieve all pressure in air, oil or water systems
before any lines, fittings or related items are dis-
connected or removed. Always make sure all
raised components are blocked correctly and be
alert for possible pressure when disconnecting
any device from a system that utilizes pressure.
(21)Do not operate a truck if any rotating part is dam-
aged or contacts any other part during operation.
Any high speed rotating component that has been
damaged or altered should be checked for bal-
ance before reusing.
