Group PS, Periodic Service
PS-1-2 • Maintenance Schedule SM 765, Nov ’06
“Periodic Service” and “Planned
Maintenance”
The term “periodic service” includes all maintenance
tasks that should be performed on a regularly scheduled
basis.
The term “Planned Maintenance” indicates a formalized
program of basic inspections, adjustments, and lubrica-
tions that the Clark service organization provides custom-
ers at a prescribed interval, usually 50-250 hours. The
recommended basic “Planned Maintenance” procedure is
given in Section 2 of this Group.
The current Section,”Maintenance Schedules,” specifies
all maintenance tasks.including Planned Maintenance
tasks.that should be performed periodically, and suggests
intervals at which they should be performed.
Determining Maintenance Intervals
Time intervals on the charts on the next four pages and
elsewhere in this manual relate to truck operating hours as
recorded on the hourmeter, and are based on experience
Clark has found to be convenient and suitable under nor-
mal operation. Standard operating condition classifica-
tions are:
Normal Operation: Eight-hour material handling, mostly
in buildings or in clean, open air on clean, paved surfaces.
Severe Operation: Prolonged operating hours or constant
usage.
Extreme Operation:
• In sandy or dusty locations, such as cement plants,
lumber mills, and coal dust or stone crushing sites.
• High-temperature locations, such as steel mills and
foundries.
• Sudden temperature changes, such as constant trips
from buildings into the open air, or in refrigeration
plants.
If the lift truck is used in severe or extreme operating con-
ditions, the maintenance intervals should be shortened
accordingly.

underside of the seat deck. This decal is a basic guide to
periodic
maintenance intervals and tasks. A more detailed chart is
supplied on the next page.
