0-5 HOW TO USE THIS MANUAL EXPLANATION METHOD 1. Operation procedure (1) The operation procedure is described in either pattern A or pattern B below. Pattern A: Explanation of each operation step with illustration. Pattern B: Explanation of operation procedure by indicating step numbers in one illustration, fol- lowed by explanation of cautions and notes summarized as point operations. Example of description in pattern B DISASSEMBLY·INSPECTION·REASSEMBLY Tightening torque unit T = N·m (kgf-cm) [ft-lbf] Disassembly Procedure 1 Remove the cover. [Point 1] 2 Remove the bushing [Point 2]  Operation explained later 3 Remove the gear. Point Operations Explanation of key point for operation with an illustration [Point 1] Disassembly: Put a match mark when removing the pump cover. [Point 2] Inspection: Measure the bush inside diameter. Limit: 19.12 mm (0.7528 in) • Step Nos. are partially sometimes omitted in illustrations. • When a part requiring tightening torque instruction is not indicated in the illustration, the part name is described in the illustration frame.  T = 46.1 ~ 48.1 (470 ~ 490) [34.0 ~ 35.5]

0-7 OPERATIONAL TIPS 1. Safe operation (1) After jacking up, always support with wooden blocks or 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 terminal before the inspection or servicing of electrical parts. 2. Tactful operation (1) 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 they are disassembled. (7) Use genuine Toyota parts for replacement. (8) Use specified bolts and nuts. Observe the specified tightening torque at the time of reassembly. Tighten to the center of the specified tightening torque range. If no tightening torque is specified, tighten the bolt or nut according to the standard tightening torque table. 3. Grasping the trouble state When a trouble occurs, do not attempt immediate disassembly or replacement but first check if the trouble requires disassembly or replacement for remedying. 4. Disposal of waste fluid, etc. When draining waste fluid from the vehicle, receive it in a container. If any oil, fuel, coolant, oil filter, battery or other harmful substance is directly discharged or scrapped without permission, it will either adversely affect human health or destroy the environment. Always sort waste fluids, etc. and treat them properly by requesting disposal by specialized companies. 5. Jack up points Front side: Jack up at the bottom surface of the frame. Rear side: Jack up at the under the counterweight. HOISTING THE VEHICLE When hoisting the vehicle, sling with wire rope(s) at the mast hook holes and the counterweight hook holes.

0-8 CIRCUIT TESTER Circuit testers are available in both the analog and digital types. They should be used selectively according to 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: Fairly accurate reading is possible, but it is difficult to observe the variation or movement. 1. 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 to its operation manual. Cautions when the polarities are different between the analog type and digital type are described below. (1) Analog circuit tester (2) Digital circuit tester Measurement result example Tester range: kΩ range Analog type Continuity exists 11 kΩ No continuity Forward Reverse Measurement result example Tester range: MΩ range Digital type No continuity 1 Continuity exists 2 MΩ Forward Reverse ∞ Forward direction Forward direction Reverse direction Reverse direction
