a week. To minimize the risk of eye injury, always wear ANSI Z87.1
approved eye protection when performing this.

cleaning the non-metallic parts of the tool. These chemicals may
weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
CHARGER CLEANING INSTRUCTIONS

exterior of the charger using a cloth or soft non-metallic brush. Do not
use water or any cleaning solutions.
