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 repe(s) with a sufficient reserve in load capacity. (3) Always disconnect the battery plugs before the inspection or servicing of electrical parts. 2. Tactful operation (1 SSTs before starting operation. (2) Before disconnecting wiring, always check the cable color and wiring state. ) Prepare the mechanic tools, necessary measuring instruments (circuit tester, megger, oil pres - sure gauge, etc.) and (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. 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. Method for battery connection upon occurrence of run - down batteries on 24 - V specification ve - hicle with 22 engine (with 12/24 V voltage switching system) (1) Connect a 12 - V aiding battery to the one on the rear side of the two mounted batteries. Mounted side (2) If starting falls with one aiding battery, connect an - other aiding battery to the front side one of the mounted batteries. Caution:
(-1 termi - nal of the aiding battery on the front side of the vehicle is connected to the body ground, connect the booster cables to the vehicle side to each corresponding termi - nal. Never connect between aiding batteries. As batteries are shorted when the negative (3) When the batteries are required to charge by the charger, remove the battery from the vehicle to charge the battery.
