Troubleshooting
Problem
While core drilling the core drill has locked/jammed
in the material
Drill is uncomfortable to use due to vibration
Tool will not start
Slow rotation speed
Slow rotation speed or no rotation plus possible visible
sparking from motor vents
Vibration or abnormal noise
Chisel mode not breaking material
Chisel tip is rotating
Drilling performance poor with masonry
Bits not fitting easily into SDS Plus Chuck (1)
10
Cause
Excess pressure on the tool at the point of
breakthrough in the material
Hammer mode is on
Core drill is not suitable for drill
Large build-up of debris inside core drill while
operating
Tool is being used for too long at one time
No power, fuse blown or circuit breaker tripped
Power cable damaged
On/Off Trigger switch faulty
Faulty motor
Tool is overheating
Carbon brushes worn
Gearbox low on grease
Internal moving parts excessively worn
Material too dense or thick
Chisel tip worn
Tool incorrectly set
Hammer mode not selected
Drill bit tip worn or damaged
Very dense material
Debris and dirt getting into chuck
Solution
Reduce pressure before breakthrough
Ensure hammer mode is off to prevent damage to cutting
teeth and reduce chance of jamming
Ensure the core drill max speed and diameter are compatible
with the drill
Regularly empty this build-up of debris to ensure safe
operation
Take frequent breaks and read the sections in this manual
regarding vibration
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
Contact an authorised service centre
Contact an authorised service centre
Contact an authorised service centre
Switch off the tool and let it cool down to room temperature.
Inspect and clean the ventilation slots
Contact an authorised service centre to have the carbon
brushes replaced
Add or replace grease
Contact an authorised service centre
Drill not suitable for material or thickness
Replace chisel
Select roto-stop mode
Enable hammer mode
Replace SDS Plus drill bit
Drilling speed will be slow in such material. A smaller pilot drill
can be drilled first to speed up the drilling process
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
