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.
