Mode Selector Dial
Do not operate the selection
dial until the tool comes to a
complete stop. Shifting during rotation of the
chuck can cause damage to the tool.
The Mode Selector Dial (Fig. 9, 4) allows the
tool to be set for various applications as listed
in the following chart:
Drilling: used for hammer-drilling
concrete
Vario-lock allows chisel to be set
in one of 12 positions
Hammering: used for chiseling
and demolition work
When using demolition or chiseling bits such as
bull points, chisels, spades, gouges, etc., the
"Hammering" mode must be selected.
"Vario-Lock"
The Vario-Lock position is intended for use with
chiseling bits such as bull points, spades, goug-
es, etc. Choose a position which is best suited
for your operation.
Turn the Mode Selector Dial (Fig. 10, 4), to the
"vario-lock" setting. Next, rotate the locking
sleeve, along with the accessory, to the desired
position. Then turn the mode selector dial to the
"Hammering" setting and slightly turn the lock-
ing sleeve to have it automatically lock into a
definite position.
