Quik-Lok®Blade Clamp Maintenance

•Periodically clean dust and debris from the Quik- Lok® Blade Clamp with dry compressed air.

•If the collar resists twisting, twist the collar back and forth to shake debris loose.

•Periodically lubricate Quik-Lok®Blade Clamp with a dry lubricant such as graphite.

Removing broken blades from the Quik-Lok®Blade Clamp

Broken blades can be removed by the following:

• Remove battery pack before removing blades.

•Point the tool downward, twist the collar, and shake the tool up and down (DO NOT turn the tool on while your fingers are holding the blade clamp open). The shank of the broken blade should drop out of the clamp.

•If shaking the tool doesn't work - In most cases, a corner of the broken blade will extend beyond the blade clamp. Twist the collar and pull the broken blade out of the clamp by this corner.

•If the broken stub doesn't extend far enough to be grabbed by its corner, use a thin blade with small teeth (such as a metal cutting blade) to hook the blade that is jammed in the clamp while twisting the collar and pull it out.
