OPERATIONAL TIPS 1.

Safe operation (1) After jacking up, always support with rigid stands. (2) When hoisting the vehicle or its heavy component, use wire rope(s) with a sufficient reserve in load capacity.

(3) Always disconnect the battery plugs before the inspection or servicing of electrical parts. 2.

(1

Tactful operation Prepare the mechanic tools, necessary measuring instruments (circuit tester, megger, oil pressure gauge, etc.) and SSTs before starting operation.

(2) Before disconnecting wiring, always check the cable color and wiring state.

(3) When overhauling functional parts, complicated portions or related mechanisms, arrange the parts neatly to prevent confusion. (4) When disassembling and inspecting such a precision part as the control valve, use clean tools and operate in a clean location.

(5) Follow the described procedures for disassembly, inspection and reassembly. (6) Replace, gaskets, packings and O-rings with new ones each time of disassembly. (7) Use genuine Toyota parts for replacement. (8) Use specified bolt and nuts. Observe the specified tightening torque at the time of reassembly. If no tightening torque is specified, tighten the bolt or nut according to the standard tightening torque table. 3.

Grasping the troule state When a trouble occurs, do not attempt immediate disassembly or replacement but first check if the trouble requires disassembly or replacement for remedying.


CIRCUIT TESTER Circuit testers are available in both the analog and digital types. The should be used selectively according t o the purpose of measurement. Analog type: This type is convenient for observing movement during operation, but the measured value should only be used for reference or rough judgement. Digital type:

1.

Fairly accurate reading is possible, but it is difficult t o observe the variation or movement.

Difference in measurement results with the digital type and analog type * The result may be different between measurements with the analog type and digital type. Always use a circuit tester according t o its operation manual. Cautions when the polarities are different between the analog type and digital type are described below.

2.

Difference in result of measurement with circuit tester The circuit tester power supply voltage depends on the tester type. 1.5V, 3.OV or 6.OV is used. The resistance of a semiconductor such as a diode varies with the circuit tester power supply voltage. The diode characteristics are shown in the figure below. The resistance values of the same semiconductor measured with t w o types of circuit testers having different power supply voltages are different.

(')

Difference in measurement result by measurement range (analog type) In the analog type circuit tester, changing the measurement range switches over the internal circuit to vary the circuit resistance. Even when the same diode is measured, the measurement result varies with the measurement range. Always use the range described in the repair manual for measurement.

RECOMMENDED BATTERIES The recommended Batteries are shown in the next table. Those batteries satisfy the minimum weight required for counter balance. For that reason, the sub-weight are unnecessary. (The maximum capacity batteries are also given for reference.)


Note: In UL-EE specifications, a battery side cover and an insulated cover on the rear of the battery hood are installed; thereby it is unnecessary to use a battery (with cover) for EE use. Battery case

BATTERY WEIGHT SUPPLEMENT ADJUSTMENT BY SUBWEIGHT It will be possible to mount a battery that does not satisfy minimum battery weight by adding a subweight in the battery compartment. The subweight must be procured locally and will not be optionally set. Taps are provided at two places on the forklift body for attaching the subweight. Subweight reference diagrams, mounting methods, principal battery subweights and required weights are shown:

DISPLAY INDICATION 1.

The display indicates the remaining battery charge level in 1 0 stages. When the remaining charge drops below 20 %, the indication flashes the warn the timing for charging.

2.

When the battery is discharged fully ( 1 0 0 %), the overdischarge alarm function operates as follows:

OVERDISCHARGE ALARM FUNCTION 1.

Material handling with traveling becomes impossible. If simultaneous operation is attempted, priority is given t o traveling and material handling is not effected. (For prevention of battery from damage by large current flow)

2.

When material handling is attempted, all indicators on the display flash and the buzzer sounds t o alarm overdischarge.

Note: Material handling operation becomes impossible on the vehicle with chopperless material handling circuit. For thirty seconds after the key switch is turned on however, material handling operation can be performed.


BATTERY ASSY REMOVAL. INSTALLATION

Removal Procedure 1

Place the mast in vertical position.

2

Disconnect the battery plug.

3

Pull the-steering unlocking lever to tilt the steering forward

4

Place the seat t o the foremost position. (When the deadman seat is used, remove the seat together with the seat stand.)

5

Release the battery hood catch. (For the battery roll-out spec. model, release the battery stoppeer. For the dust-proof spec. model, remove the battery side cover, too.)

6

Open the battery hood as holding the handle on RHS and hook the hood stay.

7

Hoist the battery Assy W/Case to relocate. (Case of the battery roll out spec., removable sidewise.)

Installation Procedure Follow the reverse sequences of the removal.


INSPECTION 1

Electrolyte inspection ( 1 ) The battery electrolyte should be colorless and transparent in normal state. Check turbidity, etc. at the time of specific gravity inspection. If clear confirmation is impossible, put in a beaker for inspection.

2

Inspection o f electrolyte specific gravity ( 1 ) Use a hydrometer and measure the specific gravity of the electrolyte Specific gravity in fully charged state: 1.280 (at 2 0 O C) Specific gravity in fully discharged state: 1.150 (at 2 0 OC) The specific gravity of the electrolyte is expressed by the value at 2 0 O C as the standard. Specific gravity conversion equation ,S, = S t + 0.0007'(t-20) :S ,, Specific gravity at 2 0 O C S t : Specific gravity at t O C t : Temperature at the time of measurement

Hydrometer

1 Duter tube

-

H o w t o use the hydrometer @ Insert the nozzle of the hydrometer into the water supply port and suck the electrolyte into the outer cylinder. @ Let the hydrometer in the outer cylinder float correctly without contact with the top, bottom and side wall of the outer cylinder, and read the graduation at the using electrolyte surface as shown at left after disappearance of bubbles in the sucked electrolyte. @ After the measurement wash outside and inside of the hydrometer with clear water and wipe thoroughly with clean cloth for storage.

3

Insulation resistance inspection Use an insulation resistance meter (megger) and measure the resistance between the battery and battery case. Insulation resistance: 1 M Q or more Note: If the insulation resistance is less than 1 MQ, remove the battery from the vehicle and wash it with water. Dry the battery case the roughly, and measure the insulation resistance again. Install the battery on the vehicle after checking that the insulation resistance is 1 M Q or more.


* Battery control table Prepare the control table for each battery t o record and retain the inspection result.

MCS-I11 CONTROLLER GENERAL The 5FBCU series is provided with the diagnostic (self-diagnosis) function for automatically detecting any abnormality in the main travelinglmaterial handling circuit, operating system such as the accelerator and sensors to sound the buzzer (peep, peep) and to display the abnormal portion by the corresponding error code on the multidisplay. A t the same time, such an action as traveling stop, material handling stop or traveling speed restriction is taken to ensure safety. When the display is set to the analyzer (fault analysis) mode, defect detection and functional check of the main drivelmaterial handling circuit, operating systems, and sensors are performed. See the Multidisplay section (page 3-3) for the diagnosis. See the Multidisplay section (page 3-71 for the analyzer.
