18 Maintain tools with care
Keep the tools in good condition and clean for
better and safer performance. Follow the
instructions for maintenance and changing
accessories. Inspect the tool cords at regular
intervals and, if damaged, have them repaired by
an authorized D WALT repair agent. Inspect the
E
extension cords periodically and replace them if
damaged. Keep all controls dry, clean and free
from oil and grease.
19 Check for damaged parts
Before using the tool, carefully check it for
damage to ensure that it will operate properly
and perform its intended function. Check for
misalignment and seizure of moving parts,
breakage of parts and any other conditions that
may affect its operation. Have damaged guards
or other defective parts repaired or replaced as
instructed.
Do not use the tool if the switch is defective.
Have the switch replaced by an authorized
D WALT repair agent.

2 Tool holder for SDS-plus
3 Mode selector with safety lock
4 Side handle
5 Depth adjustment rod
6 Depth stop clamp
Torque limiting clutch
All rotary hammer drills are equipped with a torque
limiting clutch that reduces the maximum torque
reaction transmitted to the operator in case of jamming
of a drill bit. This feature also prevents the gearing and
electric motor from stalling. The torque limiting clutch
has been factory-set and cannot be adjusted.
Variable speed
The variable speed feature allows speed to build up
slowly, thus preventing the drill bit from walking off the
intended hole position when starting. The feature also
reduces the immediate torque reaction transmitted
to the gearing and the operator if the hammer is
started with the drill bit in an existing hole.
Electrical safety
The electric motor has been designed for one
voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
Your D WALT tool is double insulated in
E
accordance with EN 50144; therefore no
earth wire is required.
Mains plug replacement
(U.K. & Ireland only)
• Should your mains plug need replacing and you
are competent to do this, proceed as instructed
below. If you are in doubt, contact an authorized
D WALT repair agent or a qualified electrician.
E

fitted with the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked
at the connection points of most good quality

in the plug (see below). Brown is for Live (L) (2)
