INSTALLING ACCESSORIES
Clean the insert shank end of the accessory to
remove any debris, then lightly grease with a
light oil or lubricant. If work is to be done
where the accessories are changed frequently
and laid in dirt, sand or concrete dust, it is best
not to grease the shank after wiping clean.
To lock standard air steel in place, Raise the
tool retainer lever all the way up and around to
the opposite side. To lock, insert air steel up to
the striker and raise the retainer lever around
the shank below the accessory collar as shown
in figure 2.
To lock Bosch internal locking steel in place,
raise tool retainer until you can slide the
internal locking steel up to the striker. NOTE:
notch on internal locking steel should always
face toward the retainer lever. To lock, lower
the tool retainer lever all the way down as
shown in figure 3.
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, reverse the previous
directions. All accessories should be wiped
clean after removing.
