4. Raise the truck only as high as necessary to perform the
maintenance work.
5. Put blocks at both sides of the truck, fully under the
frame main side structure. Put the blocks in front of but
close to the counterweight and steer wheels for best
truck stability.
Put an equal number of blocks under each side of the
truck to provide a level working position.
6. Lower the truck onto the blocks and remove the jack.
A CAUTION
Before performing any maintenance work,
check the truck for stable condition on the
blocking.
7. When maintenance work is completed, lower the rear
of truck to the floor by reversing the above procedure
and lowering each side of the truck 50 mm (2 in) at a
time:
l Put jack under frame and raise truck.
l Carefully remove blocks and lower truck.
l Remove jack and blocks from drive wheels.
Raising Entire Truck
Refer to truck data plate for truck weights.
1. Park truck safely. Lower upright fully.
2. If necessary, drive truck onto boards to increase
underclearance.
A WARNING
SIDE-TO-SIDE TIPOVER. When jacking
side of truck, be sure upright is lowered
fully. Do not raise one side of the truck
more than about 50 mm (2 in) higher than
the other, to avoid tipping truck over later-
ally.
END-TO-END TIPOVER. If the upright
and transaxle are removed while the truck
is blocked up, the truck will tip backward
due to the heavy counterweight. Upright
and counterweight must both be removed
before attempting to raise the truck for
transaxle removal. The back of the truck
must be supported by blocking under the
steer axle to prevent movement.
If the counterweight is removed while the
truck is up on blocks, the weight of the
upright and transaxle will cause the truck
to fall forward.
3. Put the jack under side frame, near the center of the
truck.
IMPORTANT
Be sure to put the jack squarely and fully
under the main side structure of the frame.
Do not put the jack under the outer covers
which enclose the hydraulic pump and con-
trols.
4. Carefully raise the truck one side at a time, only as high
as necessary to do the maintenance work, and not more
than 150 mm (6 in) total.

“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 sug-
gests 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 normal
operation. Standard operating condition classifications 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:
l In sandy or dusty locations, such as cement plants,
lumber mills, and coal dust or stone crushing sites.
l High-temperature locations, such as steel mills and
foundries.
l 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
conditions, the maintenance intervals should be shortened
accordingly.
IMPORTANT
MAINTENANCE INTERVALS. If the lift
truck is used in severe or m operat-
ing conditions, the maintenance intervals
should he shortened accordingly.
Since the operating environments of lift
trucks vary widely, the above descriptions
are highly generalized and should be ap-
plied as actual conditions dictate.

Introduction to Planned Maintenance
A program of regular, routine inspections, lubrication, and
other service tasks is important for the long life and trouble-
free operation of the lift truck.
The Clark service organization offers customers a formal-
ized program+alled Planned Maintenance, or PM-for
performing these tasks.
PM Intervals
The PM inspections, adjustments, and lubrications are typi-
cally performed on each covered truck at 50-250 hour
intervals. (See Section 1, in this Group about defining
service intervals.)
The PM Form
As an aid to service technicians performing and document-
ing PM inspections, Clark has prepared a “Planned Mainte-
nance Report” form. A copy of this form is inserted in
Section 3 of this Group.
We recommend that you use this form as a checklist and to
make a record of your inspection and truck condition. This
record can be used to inform the owner of needed repairs
and help establish the optimal PM intervals.
When you have finished the PM inspections, be sure to give
a copy of the report to the person responsible for lift truck
maintenance.
The Basic PM Procedures
The basic PM procedure is to perform checks first, repairs
and adjustments last. As you go through each step of the
PM, you should note all your findings on the PM report
form.
The PM report form serves as a record of what you did in
the PM and what further service needs to be performed.
“Further service” consists of any repair, adjustment, in-
spection, or lubrication that you discovered during the PM
or any periodic service procedure that is due but not cov-
ered by the PM agreement).
You should consult the previous PM report forms, periodic
service chart, and truck hour meter to determine what
periodic service is due. List the service due on the new PM
form.
The PM procedure, in outline form, is as follows:
1.
2.
External visual checks. Perform these as you walk
around the truck with it turned off.
Operational checks. Perform these while operating
the truck.
3.
4.
5.
6.
Internal visual checks. Perform these after removing
the floor board and cowl cover.
Air cleaning internal components. Do this while
performing the previous step.
Critical fastener torque checks.
Minor adjustments and repairs you found in your
inspection.
7.
8.
9.
10.
Fluid level checks and fill.
Chassis lubrication.
Final clean up.
Reporting your results to the responsible party.
Each of these steps is explained in detail beginning on
the next page.
A CAUTION
l Do not make repairs or adjustments un-
less authorized to do so.
l Disconnect the battery before you work
on electrical components.
l Always wear safety glasses.
l Wear a safety (hard) hat in industrial
plants and in special areas where protec-
tion is necessary or required.
l Remove all jewelry (watch, rings, brace-
lets, etc.) before working on the truck.
Truck Location and Parking
Before starting the external inspection, make sure the truck
is parked on a clean, level surface. Fully lower upright,
turn truck off, and engage the parking brake.
If it is necessary to drive the truck to a suitable inspection
location, perform the initial braking and steering checks,
given later in this Section, as you begin to move the truck.
To perform the operational checks, the truck must be where
there is sufficient clearance to raise the upright and room to
maneuver the truck at full speed without endangering per-
sonnel, equipment, or materials.

External Inspection
Walk around the truck and take note of any obvious dam-
age and maintenance problems, as follows:
Decals
Check to be sure all capacity, safety, and warning plates
and decals are attached and legible.
NOTICE
Do not operate a lift truck with damaged
or missing decals and nameplates. Replace
them immediately. They contain important
information. See Group 40 for decal loca-
tions.
Fittings and Fasteners
Make sure that fittings and fasteners are present, in usable
condition and fully fastened. Critical fastener torque checks
should be performed later--when making minor adjust-
ments and repairs.
Overhead Guard and Chassis
Be sure that the overhead guard and any other safety de-
vices are in place, undamaged, and attached securely. In-
spect welds and structural members for cracks or other
damage.
Lights and Safety Devices
Check safety devices, such as lights, horn, and audible
alarms, to make sure they are securely attached and have on
visible damage.
Static Chain
Look under the truck to ,,~---. .-i
make sure the static chain
,’
, ,.’ -..& :; ::I:
contacts the floor and is not ,’
excessively worn or loose.
See Group 13 for more in- ,’
formation. ,,.y;;;,,
l’
Leaks
Look under the truck and
on the chassis, uprights, and exposed hoses for any signs of
external leakage: brake fluid, drive axle oil, and hydraulic
fluid, and battery fluid.
When you suspect hydraulic oil leaks and loose fittings,
DO NOT USE BARE HANDS TO CHECK.
A CAUTION
HYDRAULIC FLUID PRESSURE. Do not
use your hands to check for hydraulic leak-
age. Oil may he hot or under pressure. Fluid
under pressure can penetrate your skin and
cause serious injury.
Carriage, Load Backrest, and Upright
(See Group 34 for more detailed inspection procedure.)
Inspect the welds on the carriage, load backrest, and up-
right for cracks. Be sure that the mounting fasteners are in
place and tight.
Uprigh
Rails
Carriage
3lF
3
Inspect the upright assembly: rails, carriage rollers, load
backrest, lift chains, and lift and tilt cylinders. Look for
obvious wear and maintenance problems and damaged or
missing parts. Check for any loose parts or fittings. Check
for leaks, any damaged or loose rollers and rail wear (metal
flaking).
Carefully check the lift chains for wear, rust and corrosion,
cracked or broken links, and stretching. Check that the lift
and carriage chains are correctly adjusted to have equal
tension and that the tops of the rails are within 4 mm (l/8 in)
of each other.
Check that the lift chain anchor fasteners and locking means
are in place and tight. Be sure all safety guards and chain
retainers are in place and not damaged.
Inspect the carriage stops and cylinder retainer bolts. Check
all welded connections.
Inspect all lift line hydraulic connections for leaks. Check
the lift cylinder rods for wear marks, grooves and scratches.
Check the cylinder seals for leaks.
