Usage: 1. Pull the flywheel by hand to see if it is smooth and not smooth to adjust the relevant screw (adjusted before sale). 2. Check whether the sliding parts are clean or not. Thirdly, fill the alcohol lamp up to two-thirds; alcohol above 95 degrees is the best. Fourth: Lighting the alcohol lamp on the front of the test tube, about 1 minute later, the flywheel was pulled and the engine rotated. The preheating time with the generator is slightly longer. Notes: 1. Do not touch the baked test tube to avoid scalding. 2. Lighting alcohol lamp for a long time, alcohol lamp can not be easily touched, in order to avoid burns. 3.
