Troubleshooting
Problem Cause Solution
While core drilling the core drill has locked/jammed
in the material
Excess pressure on the tool at the point of
breakthrough in the material
Reduce pressure before breakthrough
Hammer mode is on Ensure hammer mode is off to prevent damage to cutting
teeth and reduce chance of jamming
Core drill is not suitable for drill Ensure the core drill max speed and diameter are compatible
with the drill
Large build-up of debris inside core drill while
operating
Regularly empty this build-up of debris to ensure safe
operation
Drill is uncomfortable to use due to vibration Tool is being used for too long at one time Take frequent breaks and read the sections in this manual
regarding vibration
Tool will not start No power, fuse blown or circuit breaker tripped Check and replace fuse if necessary or reset circuit breaker. In
the event the fuse blows after replacing or the circuit breaker
trips again immediately contact an authorised service centre
Power cable damaged Contact an authorised service centre
On/Off Trigger switch faulty Contact an authorised service centre
Faulty motor Contact an authorised service centre
Slow rotation speed Tool is overheating Switch off the tool and let it cool down to room temperature.
Inspect and clean the ventilation slots
Slow rotation speed or no rotation plus possible visible
sparking from motor vents
Carbon brushes worn Contact an authorised service centre to have the carbon
brushes replaced
Vibration or abnormal noise Gearbox low on grease Add or replace grease
Internal moving parts excessively worn Contact an authorised service centre
Chisel mode not breaking material Material too dense or thick Drill not suitable for material or thickness
Chisel tip worn Replace chisel
Chisel tip is rotating Tool incorrectly set Select roto-stop mode
Drilling performance poor with masonry Hammer mode not selected Enable hammer mode
Drill bit tip worn or damaged Replace SDS Plus drill bit
Very dense material Drilling speed will be slow in such material. A smaller pilot drill
can be drilled first to speed up the drilling process
Bits not fitting easily into SDS Plus Chuck (1) Debris and dirt getting into chuck Clean out by positioning chuck downwards and vacuuming
while operating the chuck as if to insert bits. Ensure dust guard
is used to prevent debris entering chuck
