Note: The depth gauge cannot be used at the position where the depth gauge strikes
against the tool body.
Bit grease
Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 -1 g; 0.02 -
0.04 oz.). This chuck lubrication assures smooth action and longer service life.
7.6 CHANGING THE BIT
Before any work on the tool itself, pull the mains plug. With the SDS-max tool holder,
simpler and easier tool changing is possible without additional aides.
The dust cap 1 largely prevents the entry of drilling dust into the tool holder during operation.
A damaged dust protection cap should be changed immediately. We recommend having
this carried out by an after-sales service.
Inserting the bit (see FIG. 8)
Clean and lightly grease the shank end
of the tool. Push back the locking sleeve 2
and Insert the bit in a twisting manner into
the tool holder until it locks itself.
After installing, always make sure that the bit is
securely held in place by trying to pull it out.
Removing the bit（see FIG. 9）
Push back the locking sleeve 2 all the way and
pull the bit out.
7.7 DUST CUP
Use the dust cup (FIG. 10) to prevent dust from
falling over the tool and on yourself when
performing overhead drilling operations.
8. OPERATION
8.1 HAMMER DRILLING OPERATION
First set the mode selector switch 4 and the mode selector switch (5) to the position shown
in the figure 3.
Position the bit at the desired location for the hole, then pull the switch trigger. Do not force
the tool. Light pressure gives best results. Keep the tool in position and prevent it from
slipping away from the hole.
Do not apply more pressure when the hole becomes clogged with chips or particles. Instead,
run the tool at an idle, then remove the bit partially from the hole. By repeating this several
times, the hole will be cleaned out and normal drilling may be resumed.
WARNING! There is a considerable and sudden twisting force exerted on the
tool/bit at the time of hole break-through, when the hole becomes clogged with
chips and particles, or when striking reinforcing rods embedded in the concrete.
Always use the auxiliary handle and firmly hold the tool by both
auxiliary handle and switch handle during operations. Failure to do so may
result in the loss of control of the tool and potentially severe injury.
