will clamp the blade firmly in place.

to ensure that the blade is locked into the clamp.
4. Tug on blade to make sure it is securely locked in
place.

the arrow while pulling on the blade. Be careful
when handling hot blades.

Quik-Lok Blade Clamp Maintenance
• Periodically clean dust and debris from the Quik-
Blade Clamp with dry compressed air.
Lok ®
• If the collar resists twisting, twist the collar back and
forth to shake debris loose.
• Periodically lubricate Quik-Lok
a dry lubricant such as graphite.
Removing broken blades from the Quik-
®
Lok
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.
