Lift Truck Maintenance 8-3
Section 8. Planned Maintenance
The recommended planned maintenance and lubrication schedule
lists those items considered essential to the safety, life, and
performance of your truck with typical recommended service
intervals. Brief procedures for inspections, operational checks,
cleaning, lubrication, and minor adjustments are included for your
reference.
Your local CLARK dealer is prepared to help you with your Planned
Maintenance Program, if you want assistance. Your CLARK dealer
has specially trained service personnel who are authorized to check
your lift truck according to the applicable safety regulations.
“Section 9, Specifications,” contains useful information for selected
components, fuel and lubricants, critical bolt torques, refill capacities,
and settings for your truck.
If you have the need for more information on the care and repair of
your truck, see your CLARK dealer.
Planned Maintenance Intervals
Typical Operating Conditions
Time intervals between maintenances are largely determined by
operating conditions. For example, operation in sandy, dusty
locations requires shorter maintenance intervals than operation in
clean warehouses.
The indicated intervals are intended for normal operation. The
following operating conditions are defined:
Normal Operation: Standard, eight-hour material handling, mostly
in buildings or in clean, open air areas on paved surfaces.
Severe Operation: Prolonged operating hours and/or constant use.
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, foundries, etc.
• Sudden temperature changes, such as: constant trips from
buildings into the open air, refrigeration plants, etc.
If your fork lift truck is used in severe or extreme operating
conditions, you must shorten the maintenance intervals accordingly.
Since the operating environment of lift trucks varies
widely, the above descriptions are highly generalized and
should be applied as actual conditions dictate.
