FOREWORD
The new TCM’s FB-8 Series battery-powered forklift trucks are provided with a newly designed
speed control system and AC motors for both the traveling and load handling systems to assure
high performance operation.
The trucks of this series are also provided with a self-diagnosis function which keeps watching
the operating statuses of the main control systems of the truck. If the truck has a trouble, the
function detects the trouble and displays the result of diagnosis. The maintainability is thus
improved.
As for mobility, since the high capacity batteries and high power drive motor are used, the rst-
class acceleration, gradeability, and traveling performance are achieved.
Controllability is also improved by the standard equipped power steering unit.
To save power, the acceleration and traveling speeds are selectable and made changeable
according to working conditions. Also for effective use of the battery, a regenerative device is
provided to send back counter electromotive force to the battery.
This Service Manual is intended to provide the maintenance personnel with helpful information
of the structures of the major components and with instructions on the maintenance and repair of
such components. We hope it will be much help for your servicing and maintenance operations.

01. CAUTION TO TAKE WHEN SERVICING THE TRUCK
* Before servicing the truck, make sure to:
1. Park the truck on a level surface and jack up the drive wheel off the oor or ground.
Make sure there is no obstacle above and around the truck before operating the load handling
system.
* Caution to take when measuring, inspecting or repairing:
2. Before connecting or disconnecting wire harness couplers, make sure the key switch is turned off
and the battery receptacles are disconnected.
3. When measuring the resistance of wire harness couplers with a multimeter, connect the probes to
the lead wire side of the coupler.
4. When inspecting the truck with the forks raised, support the forks to prevent them from falling
unexpectedly.
5. When inspecting the truck with the mast advanced, put a pallet between the mast and the front
guard of the truck to prevent the mast from retracting unexpectedly.
6. Inspection and repair of the truck must be performed only by qualified service personnel
authorized by TCM.

02. BASIC SERVICING KNOWLEDGE
1. Installing bearings
When installing a bearing onto a shaft, tap its
inner race with a mallet as shown in Figure 02.1.
When installing a bearing into a case, tap its outer
race.
When removing, use the same procedure as for
installing.
2. “O”-rings
①Use “O”-rings free from molding fault or damage.
②Clean “O”-rings and their mounting area and apply grease or hydraulic oil to them.
③When installing “O”-rings, do not expand them so excessively that they suffer permanent
deformation. Also do not roll them when installing; otherwise they might stay twisted, causing oil
leakage.
④When using an “O”-ring and back-up ring as
a set, such as when hydraulic pressure is high,
position the “O”-ring at the side which receives
the oil pressure.
3. Oil seals
①Oil seals should be installed with the seal lip pointed toward the lubrication or hydraulic oil.
②When installing an oil seal on a housing, apply a thin coat of packing cementing agent on the
oil seal outer ring and inside the housing to prevent oil leakage through the fitting area. It is
recommended to use a suitable jig to apply uniform pressure when mounting oil seals.

JIG
Fig. 02.2 “O”-ring location
Pressure
Fig. 02.3 Installing Oil Seal
JIG JIG JIG

③When installing an oil seal onto a shaft, apply
lubricating oil or grease to its seal lip and the
mounting surface of the shaft. For a double-
lip type, fill grease by 1/3 to 1/2 of the space
between the lips.
When inserting an oil seal into a case, use care
to damage the seal lip. It is good practice to use
a suitable conical sleeve.
4. Using LOCTITE
(1) Procedure for using LOCTITE
①Clean or degrease the surface of parts you are going to apply LOCTITE, using trichloroethylene,
acetone, ether or alkaline solution.
② Blow dry them with compressed air or allow to air dry at room temperature sufciently.
③ Apply specied LOCTITE.
(2) Removing parts
When removing parts which were installed with the application of LOCTITE, use tools such as a
spanner, wrench, and pulley remover.
If you fear that a part may break due to the effect of LOCTITE if forcibly removed, heat the part to
200 to 250°C [392 to 482°F] with a soldering iron or gas burner.
Remember that parts are very hot after heating. Use caution not to get burnt when
removing them.
(3) Reinstalling parts
①When destroyed, LOCTITE remains as white powder on the threads of bolts.
You can apply a
new coat of LOCTITE again over their surface.
Note: For example, if a bolt turns slightly due to bolt torque checking, remove the bolt and apply
LOCTITE again and reinstall.
② If LOCTITE is used for the surface of a ange, it is necessary to remove hardened LOCTITE with
a wire brush when reinstalling the ange.
5. How to use a power wrench
Power wrenches have their respective torque multiplying factors. Refer to the product catalog of
each power wrench.
It should be noted that a value obtained by multiplying the output torque of a torque wrench by the
multiplying factor of a power wrench is not necessarily an output torque.
Remember this especially when the tightening torque is strictly specied.

03. CLEANING
1. General metallic parts
① Clean parts thoroughly using cleaning uid. It is recommended that parts be immersed in cleaning
uid and moved up and down slowly until all old lubricant and foreign material is dissolved and
parts are thoroughly cleaned.
②Cast parts should be cleaned with cleaning solvent or steam cleaned.
③If a part is severely contaminated, use a wire brush or a piece of wood or metal to scrape off
contaminants from the part. Wash it in cleaning fluid once, before cleaning it completely.
However, do not use a wire brush for cleaning sliding surfaces or machined surfaces.
④Oil passages must be cleaned with a steam cleaner. After checking for clogging with a piece of
wire, they also should be cleaned with cleaning uid or with compressed air.
⑤Some parts may be cleaned in hot solution tanks with mild alkaline solution. Parts should remain
in solution long enough to be thoroughly cleaned and warmed.
This will aid the evaporation of the cleaning solution and rise water. Parts cleaned in solution
tanks must be thoroughly rinsed with clean water to remove all traces of alkali.
 Careshouldbeexercisedtoavoidskinrashes,rehazardsandinhalationofvaporswhen
using solvent type cleaners.
⑥If alloy parts, such as bearing shells or bushings, are cleaned with alkaline solution, they are apt to
corrode due to ionization. Such parts should be cleaned with kerosene, Tricrene solvent vapor or
“Magnus” uid.
⑦After cleaning, parts must be thoroughly dried with compressed air.
2. Bearings
①To dislodge solidified particles of lubricant, immerse bearings in cleaning fluid and remove
them from the uid. On a clean work bench, tap the bearing softly with a soft mallet to dislodge
solidied particles.
②When drying bearings, be careful to direct air stream across bearing to avoid spinning.
3. Rubber parts
①When rubber parts need to be cleaned, use alcohol or wipe them clean with a soft cloth.
②Never use gasoline, diesel fuel or kerosene for cleaning. Use the same kind of oil for which the
rubber part will be used.

04. STANDARD BOLT TIGHTENING TORQUE
See the section “04. STANDARD BOLT TIGHTENING TORQUE” for the torques of standard
bolts when they are used for general applications. Refer to the Shop Manual and Service Manual of
your truck model when:
1) Special nuts are used.
2) Synthetic resin or rubber is used for tightening.
3) Specied tightening torque is given.

05. LUBRICATION
1. Lubricating lift chains
Lubricate the lift chains with engine oil using an oiler or a brush.
To allow oil to enter between each pin and link plate of the lift chain, observe the following
conditions:
Loosen the chains sufciently.
•
After applying engine oil, operate the lift cylinders at least ten times through full travel.
•
NOTE
If your lift truck is used near a port or coastal area, the lift chains might be damaged from salty
breezes. After a storm or typhoon, it is advisable to wash them with water before lubricating in the
above manner.
2. Mast and steering system
Fig. 05.1
Fig. 05.2
■Rear slippers of the mast
WARNING
Do not ride on the mast. Do not put your hand or
foot on the connecting member across the mast
or between the outer and inner mast channels;
otherwise you might get injured if the mast
accidentally moves.

3. Checking hydraulic oil level
Check the hydraulic oil level in the hydraulic oil
tank using the oil level dipstick.
Remove the dipstick of the tank cap, clean the rod
with a clean cloth and reinsert it. Remove the dipstick
again and check the oil level. If the level is low, add
hydraulic oil.
[How to read oil level]
“H” mark: Highest position of the standard truck
“L” mark: Lowest position of the standard truck
“S” mark: For trucks with a lift height of 6 m or more
or for special trucks, the oil level should be
within 10 mm above or below this mark.
NOTE
Too high oil level might cause oil leakage.
•
The oil level check should be performed with the
•
mast vertical, the forks on the ground or floor
surface, and the truck parked on a level surface.
