Toyota Pallet Truck Service Manual Safety Static Safety Static Safety (mat). Follow the instructions packaged with this kit. Electronic circuit boards and devices used on this truck can be damaged by the discharge of static electricity, called electrostatic discharge. Wrist straps are available in quantities of 25, as part number 00590-04848-71. Static charges can accumulate from normal operation of the truck as well as movement or contact between non-conductive materials (plastic bags, synthetic clothing, synthetic soles on shoes, styrofoam coffee cups, and so forth). A wrist strap tester is available as part number 00590-04850-71. Contact your authorized Toyota dealer for information.
Accumulated static can be discharged thru human skin to a circuit board or component by touching the parts. Static discharge is also possible thru the air when a charged object is put close to another surface at a different electrical potential. Static discharge can occur without you seeing or feeling it. Whenever working on or near static-sensitive electronics, always use static discharge precautions. 1. Put a static discharge wrist strap around your wrist. Connect the ground lead to the wrist strap connector. 2. Connect the ground strap to an unpainted, grounded surface on the truck frame. 3.
If you are removing or installing static-sensitive components, put them on a correctly grounded static mat. Figure 2-2. Anti-Static Kit (P/N 00590-04849-71 ) With Wrist Strap and Mat 4. To transport static-sensitive components, including failed components being returned, put the components in an anti-static bag or box (available from your Toyota dealer). The wrist strap and associated accessories should be tested monthly to verify they are working correctly. The wrist strap contains a one megohm resistor in the strap cord that acts as a fuse for personal protection. If this resistor is open, the strap becomes ineffective.
