CHUCK
It has been found that electric tools are subject to accel- erated wear and possible premature failure when they are used on fiberglass boats, sports cars, wallboard, spackling compounds, or plaster. The chips and grindings from these materials are highly abrasive to electric tool parts, such as bearings, brushes, commutators, etc. Consequently, it is not recommended that this tool be used for extended work on any fiberglass material, wallboard, spackling compounds, or plaster. During any use on these materials, it is extremely important that the tool is cleaned frequently by blowing with an air jet.
WARNING:
Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.
TO RETIGHTEN A LOOSE CHUCK
See Figures 10 -11.
The chuck may at times become loose on the spindle and develop a wobble. Also, the chuck screw may become loose causing the chuck jaws to bind and prevent them from clos- ing. To tighten, follow these steps:
nUnplug your drill.
WARNING:
Failure to unplug your drill could result in accidental starting causing serious injury.
nInsert hex key into chuck and tighten chuck jaws securely. Tap hex key sharply with a mallet in a clockwise direc- tion. See Figure 10. This will tighten the chuck on the spindle.
nOpen the chuck jaws and remove the hex key.
nTighten the chuck screw.
NOTE: The chuck screw has left hand threads.
