INSTALLING ACCESSORIES
Clean the insert shank end of the accessory to
remove any debris, then lightly grease with a
light oil or lubricant
Insert accessory into the tool holder through
the dust shield, while twisting and pushing
inward until it locks automatically into place.
Pull outward on the accessory to be certain it
is locked into the tool holder (fig. 2).
NOTE:
The high efficiency available from the
rotary hammers can only be obtained if sharp
and undamaged accessories are used. The
"cost" to maintain sharp and undamaged
accessories is more than offset by the "time
saved" in operating the tool with sharp
accessories.
REMOVING ACCESSORIES
Accessories may be hot after
use. Avoid contact with skin
and use proper protective gloves or cloth to
remove.
To remove an accessory, pull and hold locking
sleeve backward and pull bit forward. All
accessories should be wiped clean after
removing (Fig. 3).
