Cautions
The following is a list of “CAUTIONS” connected with the operation andmaintenance of trucks
equipped with Solid State Control Panels.
Safety Signs and Safety Messages
SAFETYSIGNSand MESSAGESareplaced in this manual and also on the truck to provide instructions and
to identify specific areas where potential hazards exist and special precautions must be taken. Be sure you know
and understand the meaning of these instructions, signs and messages. Damage to the truck or serious injury
to you or other persons may result if these messages are not followed. If warning decals are damaged they must
be replaced. Contact your Clark dealer for replacements.
NOTICE This message is used when special information, instructions or identification is
required relating to procedures, equipment, tools, pressures, capacities and other
special data.
IMPORTANT This message is used when special precautions should be taken to ensure a correct
action or to avoid damage to or malfunction of the truck or a component.
A
! CAUTION This message is used as a reminder of safety practices which can result in personal
injury if proper precautions are not taken.
A WARNING This message is used when a hazard exists which can result in serious personal
injury or death, if
proper precautions are not taken.
A DANGER This message is used when an extreme hazard exists.
A WELDING ON TRUCKS
1. Make sure the truck has no grounds.
2 Disconnect truck battery.
3. Protect electrical wiring and components from weld spatter with
a shield.
4. Ventilate battery or remove battery from truck.
Ifthe above isnotfollowed, damagecan resultto wiring andelectrical
components on a solid state control truck.
SM-587 i Dee 94

CAUTIONS
A DO NOT STEAM CLEAN
Do not steam clean a solid state controlled truck as excessive moisture
will interfere with proper operation of the solid state components.
Solid State Controls should be cleaned atregularintervals. Blowing dirt off with an air hose (that
is restricted to 30 psi [207 kPa]) periodically will, for the most part, eliminate any serious
cleaningproblems. Should the need arise for amore thorough cleaning, water may be hosed over
the control and if necessary a mild detergent applied such as that used in washing dishes in our
home. The detergent should be rinsed off and the controls must be thoroughly air dried before
putting truck into service.
Periodic cleaning, such as those mentioned above, should preclude the need for using a
degreaser. However, if a degreaser is used we recommend the following:
Only approved solvents should be used to clean Solid State Control Components. Use Clark
#I1801146 Degreaser, or the equivalent to MS- 180 Freon TF Degreaser and Cleaner.
A CHECK POLARITY
Battery Polarity must be correct or the truck will not
operate.
A USE TRUCK BATTERY ONLY
Do not use a motor generator unit such as “ready
power” or a battery charger to move and/or check this
truck as serious damage may occur
IMPORTANT SAFETY NOTICE
Read and understand all Safety Precautions and Warnings before
performing repairs on lift trucks.
Appropriate servicemethodsandproperrepairproce-
dures are essential to the safe, reliable operation of
industrial trucks as well as the personal safety of the
individual doing the work. This Service Manual
provides general directions for accomplishing service
and repair work with tested, effective techniques.
Following them will help assure successful repair and
reliable truck operation.
There are numerous variations in procedures, tech-
niques, tools and parts for servicing industrial trucks,
as well as in the skill of the individual doing the work.
This manual cannot possibly anticipate all such varia-
tions and provide advice or precautions as to each.
Accordingly, anyone departing from the instructions
provided in this manual through procedures used or
choice of tools, materials, and parts may jeopardize
his or her personal safety and/or the safety of the
vehicle user.
Improper or careless techniques cause accidents. Don’t
take chances with incorrect or damaged equipment.
Read and understand the procedures for safe opera-
tion and maintenance outlined in this manual.
Drive and work safely and follow the safety signs and their messages
displayed in the work area, on the truck and in this manual.
Dee 94 ii SM-587

Cautions
GENERAL PRECAUTIONS
Thefollowing list contains general precautions that should be followed when working
on a lift truck.
Service Electric Truck Batteries in a well-venti-
lated area to avoid the danger of lighting explo-
sive gases, clear of pedestrians and with ad-
equate overhead clearance and on a flat, level
surface.
Always wear safety glasses for eye protection.
Remove rings, watches, loose jewelry and open
clothing before working on a vehicle, to avoid
serious injury.
Do not smoke while working on a vehicle.
Putpowerkey switchintheOFFposition,unless
otherwise required by the procedure.
Set the parking brake. Place chocks to the front
and rear surfaces of the tires to provide further
restraint from inadvertent vehicle movement.
Use safety stands or blocks whenever a proce-
dure requires you to be under the vehicle.
Follow the Safety Instructions outlinedin Group
12, “Handling Storage Batteries”.
Always Discharge the Capacitors prior to work-
ing on or around electrical components. Refer to
the instructions outlined in Group 19, “Dis-
charging Capacitors”.
A
! CAUTION
Avoid contact with Battery Acid. The battery contains corrosive acid which
can cause injury. Follow the instructions outlined in Group 12 “Handling
Storage Batteries” and those instructions received with your battery and
charger.

Foreword
This Service Publication provides information
covering normal service, maintenance and repair of
the Clark industrial lift trucks noted on the cover. It
has been specifically prepared to help owners and
service personnel maintain these trucks in efficient
and safe operating condition.
This manual isintended for use bypersons who
are trained and authorized to do lift truck mainte-
nance. It is designed to provide essential information
about the correct and safe service maintenance and
repair of the truck by trained mechanics or service
technicians.
The information is organized by use of the
Basic Group Numbering System used in the
Master Parts Book and the Customer Parts Manuals.
The manual includes:
P.M.
Planned Maintenance Procedures
including precautions and safe
maintenance recommendations.
01-40
Service specifications, adjust-
ments, maintenance and overhaul
procedures including lubrication
charts, recommended lubricants
and service weights, etc.
General and detailed service and repair
procedures are outlined (as required) for each
component or subsystem. Some procedures include
explanations that are common to several components
or subsystems.
The PictorialIndex lists components or systems
by Basic Group Number of Major Parts. Additional
content listings are placed at the beginning of each
Section in the manual.
The Table of Contents list the pages in this
manual.
Procedureshavebeen made easiertouseby
providing specific steps only when necessary and
general instructions required to explain the activity,
component, assembly, or process being worked on.
The technician is expected to include obvious addi-
tional steps of standard procedure for removal, disas-
sembly, cleaning, inspection, reassembly, installa-
tion, etc., as needed.
Tobebetterpreparedto dothenecessaryservice

ABOUT PLANNED MAINTENANCE
The Planned Maintenance Procedures
located in the front of this manual provide a basic step
by step guide which should be followed in servicing
the vehicle. Adjustment Procedures, Specifications,
Lubrication Guides, Overhaul Procedures and other
data are found in the rear of this manual listed under
Group and SectionNumbers. Refer to the index.
Regular, correct maintenance and care of
industrial trucks is not only important for long and
efficient truck life but it is essential for safe operation.
The importance of proper maintenance through
planned service, inspection and qualified repairs can-
not be emphasized too strongly. Preventive mainte-
nance instructions are provided for reference in set-
ting-up and conducting a recommended periodic
Planned Maintenance (PM) program.

Foreword
An effective PM program should incorporate
two basic phases: ~
1.
2.
An insnection net-formed bv the driver or main-
tenance man at the beginning of each shift. This
is a quick visual check for obvious damage and
leaksandafunctionaltest...acheckoffluidsand
water levels,lights(ifsoequipped),instruments
and warning devices.
The Planned Maintenance routine is based on
50 to 250 operating hours ... with the interval
being determined by operating conditions.
Records will tell you how often PM
should be done.
l If an oneration is clean and not strenuous, a PM
interval can be extended.
l If an oneration is extremelv dirtv and strenuous,
the PM interval may have to be reduced.
If the PM is faithfully followed, needs for
repair, major adjustment and component replace-
ment will be discovered and such work can be
scheduled eliminating unnecessary downtime and
cost. For instance, brake checks which are part of the
PM will uncover the need for adjustments and/or
repairs which may be required periodically.
The objectives of PM are:
1. To reduce costly unscheduled downtime.
2. Reduce maintenance costs.
3. Increase vehicle productivity.
4. Increase personal safety of drivers and other
personnel.
Inspection Forms
To insure that the daily inspection and PM are prop-
erly performed, we recommended the use of inspec-
tion forms. Such forms not only provide a guide for
the inspections and maintenance requirements for
eachvehicle, they will assist you in determining when
to schedule avehicle for major repairs. Consequently
theserepairscanbedonewithoutthedisruptiveeffect
of unscheduled down time.
NOTE
Refer to the Operator’s Manual,
located on the truck, for additional
information on the operation, care
and maintenance of your truck.
Contact your authorized Clark
dealer for more information on
maintenance and repair of these
t?-UCkS.

The Planned Maintenance Procedures
Outlined
on the following pages are organized in
five basic catagories. They are:
1. Walk Around Visual Inspection.
2. Operational Tests.
3. Cleaning.
4. Checks and Minor Adjustments.
5. Lubrication.
Each catagory is preceded with a summary of the
inspections, checks, tests, etc., that should be per-
formed in each catagory.
P.M. CHECK SHEET
A special coding system on the P.M. Check sheet
allowstmckcondition tobereportedwithaminimum
number of words. As the P.M. is performed, a mark
should be made in the appropriate box of the compo-
nent being checked.
l (4) indicates the particular truck component or
system has been checked.
l (x) indicates the component or system is in need
of a minor adjustment or service (not part of the
normal P.M.) that should be taken care of in the
near future.
l (r) indicates there is a potential problem that
couldresult in damage to acomponent or system
and requires attention.
l (s) indicates the need for urgent repair or replace
ment of a component or system and the truck
should be shut down as possible property dam-
age or personel injury may result.
The nature of problems found during aP.M. shouldbe
noted in the “comments” portion of the check sheet.
Whenever a system or comnonent is faultv or unsafe,
it must be noted on the check sheet andreported to the
designated authority at the conclusion of the P.M.
