2. Apply the parking brake and place the shift lever in neutral.
3. Attach a tachometer to the engine and turn off all electrical devices.
4. Start the engine and warm it up to normal temperature, then increase the speed to 2500-3000 rpm and hold it for three minutes.
5. Stop the engine and connect an exhaust gas analyzer to the muffler outlet pipe.
6. Start the engine at idle speed. If the electric cooling fan is running, wait until it stops.

8. To adjust the mixture, first disconnect the air injector pipes from the air filter and plug them.
9. Warm up the engine for three minutes at a frequency of 2500 to 3000 rpm, then let it idle. If the electric cooling fan is running, do not wait for it to stop.
10. Check the CO level as given in Specifications. If it is not correct, remove the rubber plug from the air filter and turn the bypass air adjustment screw as needed using the Mazda Special Tool, part number 49 HC27 140.

11. Install the rubber plug, then adjust the idle speed as described in Step 7.
Checking and adjusting the ignition timing (EGI engine)
12. The procedure is mainly described in Section 1, Chapter 34, but in addition, the hose must also be disconnected and included (And) vacuum distributor capsules before checking and adjusting the ignition timing.

Checking the rear disc brake
13. Check the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove rear wheels.
14. Looking through the slots at the back of each caliper, check that the lining material on each pad is at least 1.0mm thick. Where less, replace all four rear pads at the same time.
15. Check up tubes of a highway of a high pressure of a brake system, check up a support on damage and leaks.
16. Check the rear discs for working depth, and if necessary, replace them.
17. Install the rear wheels and lower the vehicle to the ground.
Checking and adjusting the shock absorber (EGI engine)
18. Hold the throttle fully open, then depress the shock absorber rod with your finger and check that the rod moves slowly. After you release the rod, it should move quickly.
19. To adjust it, first start the engine and warm it up to normal temperature.
20. Stop the engine and connect the tachometer.
21. Start the engine at 3500 rpm, then slowly reduce it and check that the throttle lever touches the shock absorber rod at 3000±100 rpm.
22. If necessary, loosen the jam nut and reinstall the damper (photo).
