Safety Information
• The instructions provided herein are only for general information. ALWAYS perform all repairs in full compliance with
your machinery’s service manual. After any repair, test your engine and machinery in your workshop and at low speed
before returning to regular use. Failure to do so may result in serious property damage and severe personal injury.
• DO NOT allow use by children, persons whose mental or physical condition precludes safe use, or persons unfamiliar
with this product and its compatible vehicle systems.
• DO NOT use while under the influence of alcohol, drugs, or any medication that negatively affects your judgment or
reflexes. Keep children and bystanders away during use.
• Keep your work site clean and well-lit. Poorly lit and cluttered work areas increase the risk of accidents and should be
avoided.
• ALWAYS use personal protective equipment (PPE) suitable for your task. ALWAYS wear ANSI and OSHA-approved
eye, breathing, and hand protection while using this product. Regular use of this product typically produces microscopic
particles known to the state of California to cause cancer, congenital disabilities, or other reproductive harm. Nonslip
footwear is also highly recommended. Other equipment such as ear, head, and body protection may also be necessary
depending on your work, work environment, and other equipment.
• ALWAYS read and understand your machinery's specific safety warnings and instructions before using this kit. Use
the correct fluids, pressures, adapters, etc., for your machinery. Make sure the machinery is fully supported and parked
before beginning any work. NEVER touch any heated surface with exposed skin.
• Before servicing your machinery, turn off its engine and refer to its manufacturer's service and repair manual for
instructions on safely securing the machinery with chocks, jacks, stands, etc.
• In case of an accident or injury, have a first aid kit and a communication device (e.g., a phone) readily available. Know
the location of emergency medical facilities.
• Machinery repair is an inherently dangerous activity. This manual and the separate machinery service manual cannot
cover all possible situations that may arise. ALWAYS exercise discretion and good judgment. Seek training if needed.
• For best results, keep the kit clean and dry. Remove any fluid, oil, or grease before and after work.
• Dress appropriately for automotive servicing. DO NOT wear loose clothing or jewelry, and keep hair, clothing, gloves,
hoses, and tools away from any moving parts during use.
• If a component is particularly stubborn, avoid applying excessive force that could damage the puller or the workpiece.
Instead, apply penetrating oil, allow it time to work, and gradually apply force.
• Maintain this product. Check for misalignment, binding, wear, or other damage before use. If any damage is detected,
repair or replace the defective components before further use. In a large shop, mark such tools “DO NOT USE” until
they have been repaired. ONLY replace components with identical parts.

Operation
• Shut off the engine before servicing, set the parking or hand brake, and chock the other
wheels. Ensure the vehicle is stationary and the engine has cooled to room temperature
before performing maintenance or adjustments.
• ALWAYS use the correct tools and personal protective equipment (PPE) before
performing any operation. Be extremely careful with possible pinching points, moving
parts, or parts that may suddenly spring out.
• ALWAYS ensure the vehicle is secure when supported by a jack or lift.
• For your safety, we recommend completing training before using these tools. Serious
injury could happen due to a lack of training.
