Gear pullers are made in various shapes and sizes and have many uses. Always use the correct tool for the job.

• Wear safety glasses or a faceshield.
• Select the proper gear puller for each pulling job. Always use a gear puller of the required size or larger. Use a 3-jaw puller, if possible.

• Ensure that the gear puller is aligned with the shaft. The jaws should be parallel with the screw. This assures a straight pull.
• Be careful when removing a stubborn gear or bearing. Always strike the head of the centre screw squarely. If after two sharp blows the gear or bearing remains stuck, select a larger puller and proceed to remove the gear or bearing.
• Cover work with a cloth to protect you and by-standers from flying parts.
• Lubricate the centre screw with machine oil before use.
• Clean the gear puller after use and store it in a dry place.

• Do not use air powered tools on gear pullers.
• Do not use any puller with functioning parts that show excessive wear, dents, or cracks. Inspect the centre screw for signs of galling or seizing.
• Do not heat any gear puller. It will lose its strength and break under pressure if heated.
• Do not cut or grind any part of a gear puller.
