Safety Considerations

• While this product is designed to be water-
resistant, it should never be submerged
under water or subjected to high-pressure
water spray.
• Do not mount in areas of extreme heat.
• Ensure this product is securely installed so
that it does not come loose in the event
of a collision/sudden jolt or as a result or
repeated vibrations during normal operation.
• Check before drilling to make sure that you
will not be drilling into a fuel tank, gas/brake
line, wiring harness, or other vital system.
• Secure all wiring as needed, using cable
ties or wire clamps to protect them from
moving parts and sharp edges.
• Always follow proper safety procedures and
wear eye-protection at all times with a dust
mask and gloves when cutting.
