[. . . ] - Inspect the fuel cap regularly to make sure that it is securely fastened and does not leak. Change the location to start the engine (at least 3 meter away from the place of refueling). - Only use the Brush Cutter/String Trimmer in good light and visibility. During the winter season, always be aware of slippery or wet area, ice and snow. Foreign materials may damage the cutting tool and cause dangerous kick-back. - The cutting tool must have reached full working speed before contact with the grass. This is particularly the case when attempting to cut within a blade segment between 12 and 2 o'clock. Never use the brush cutter within a segment between 12 and 2 o'clock. Never apply the blade of brush cutter to solids, such as bushes and trees, etc. , having a diameter in excess of 3 cm or the brush cutter will be deflected at great force with the risk of injuries. To avoid kickback, ensure the following : - Operation within a blade segment between 12 and 2 o'clock presents positive hazards, especially in using metal cutting tools. - Cutting operations within a blade segment between 11 and 12 o'clock, and between 2 and 5 o'clock, must only be performed by trained and experienced operators, and then only at their own risk. Easy cutting with almost no kickback is possible within a blade segment between 8 and 11 o'clock. - The condition of the Brush Cutter/String Trimmer must be checked before operation, in particular of the cutting tool, the protective devices and also the shoulder strap. Special attention must be paid to the cutting blade which must be correctly sharpened. - Fix a barrier to the left side of the machine together with the handle of operator's protection. - Do not adjust position of the loop handle too close to the control grip. - The handle must be kept in position more than 250 mm from the hanger. To meet the applicable safety provisions, only the tool/protector combinations as described in the table must be used. If the cutter blade hits against a stone during operation, stop the engine and check the blade immediately. 20 Sharpen or replace the cutter blade every three (3) hours of operation. If the nylon cutting head hits against a stone during operation, stop the engine and check the nylon cutting head immediately. [. . . ] Before operation, check the machine for loose screws or missing parts. Before operation, always check for clogging of the cooling air passage and the cylinder fins. Do the following works daily after use : - Clean the machine externally and inspect for damage. When working under extremely dusty conditions, clean the filter several times a day. [. . . ]
