Assembly And Adjustment - DeWalt D25840 Instructions Manual

Assembly and adjustment

Prior to assembly and adjustment always
unplug the tool.
Inserting and removing SDS-max
(fig. C1 & C2)
This machine uses SDS-max
(refer to the inset in fig. C2 for a cross-section of an
®
SDS-max bit shank).
• Clean and grease the bit shank.
Only apply a slight amount of lubricant to
the bit shank. Do not apply lubricant to
the machine.
• Insert the bit shank into the tool holder (6),
and press and turn the bit slightly until the sleeve
snaps into position.
• Pull on the bit to check if it is properly locked.
The hammering function requires the bit to be
able to move axially several centimetres when
locked in the tool holder.
• To remove a bit pull back the tool holder locking
sleeve (6) and pull the bit out of the tool holder.
Indexing the chisel position (fig. D1 & D2)
The chisel can be indexed and locked into 24
different positions (fig. D2).
• Rotate the mode selector switch (5) until it points
towards the „0" position.
• Rotate the chisel in the desired position.
• Set the mode selector switch (5) to the
„hammering only" position.
• Twist the chisel until it locks in position.
Setting the electronic speed and impact control
dial (fig. B)
• Turn the dial (2) to the desired level. Turn the dial
upwards for higher speed and downwards for
lower speed. The required setting is a matter of
experience. E.g.:
– when chiselling or drilling in soft, brittle
materials or when minimum break-out is
required, set the dial to a low setting;
– when breaking or drilling in harder materials,
set the dial to a high setting.
