ENGLISH
E.g.:
- when chiselling soft, brittle materials or when
minimum break-out is required, set the dial to
“1” or “2” (low);
- when breaking harder materials, set the dial to
“7” (full power).
Assembling and fitting the side handle (fig. E)
The side handle (8) can be mounted on either side of
the machine to suit both RH- and LH-users.
Always operate the tool with the side
handle properly assembled.
• Snap the steel ring (13) over the collar (7) behind
the tool holder (6). Squeeze both ends together,
mount the bush (11) and insert the pin (12).
• Place the side handle (8) and screw on the clamp
knob (9). Do not tighten.
• Rotate the side handle mounting assembly to the
desired position.
• Lock the side handle mounting assembly in place
by tightening the clamp knob (9).
Instructions for use
• Always observe the safety instructions
and applicable regulations.
• For your own safety, always use the tool
with both hands.
• Be aware of the location of pipework and
wiring.
• Apply a pressure of approx. 20 kg to the
tool. Excessive force does not speed up
chiselling but decreases tool
performance and may shorten tool life.
Switching on and off (fig. F)
• To switch on the tool, press the on/off switch (1).
• For continuous operation, depress the lock-on
button (14) on the on/off switch.
• To stop the tool, press the on/off swith again.
Chipping and chiselling (fig. A)
• Insert the appropriate chisel and rotate it by hand
to lock it into one of 8 positions.
• Set the electronic speed and impact control dial (2).
• Fit and adjust the side handle (8).
• Switch on the tool and start working.
• Always switch off the tool when work is finished
and before unplugging.
Various types of SDS-max
®
chisels are available as
an option.
Consult your dealer for further information on the
appropriate accessories.
Maintenance
Your DEWALT Power Tool has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
Tool maintenance has to be carried out as soon as
the indicator LED lights up.
• This machine is not user-serviceable. Take the
tool to an authorised DEWALT repair agent after
approximately 80 hours of use. If problems occur
before this time contact an authorised DEWALT
repair agent.
Accessory maintenance
Accessory maintenance at the right time guarantees
optimal results in application and a long and efficient
accessory life.
• Grind the chisels on grinding discs. Refer to fig. G
for the appropriate angles of the following chisels:
- spade-shaped chisel (15)
- cold chisel (16)
- pointed chisel (17)
- U-shaped chisel (18)
- hollow chisel (19)
- mortar chisel (20)
- toothed chisel (21)
These chisels can be reground only a
limited number of times. If in doubt,
contact your dealer for recommendations.
Ensure that the cutting edge does not
show discolouration caused by too
much pressure. This may impair the
hardness of the accessory.
Lubrication
Your power tool requires no additional lubrication.
