WARNING: The operating mode selector switch
may be actuated only at a standstill.
9. OVERLOAD PROTECTION
When overloaded, the motor comes to a stop. Relieve
the load on the machine immediately and allow
cooling for approx. 30 seconds at the highest no-load
speed.
10. TEMPERATURE DEPENDENT OVERLOAD
PROTECTION
When using as intended for, the power tool cannot be
subject to overload. When the load is too high or the
allowable battery temperature of 75 °C is exceeded,
the electronic control switches off the power tool until
the temperature is in the optimum temperature range
again.
11. PROTECTION AGAINST DEEP DISCHARGING
The Li-ion battery is protected against deep
discharging by the "Discharging Protection System".
When the battery is empty, the machine is switched
off by means of a protective circuit: The inserted tool
no longer rotates.
WORKING HINTS FOR
YOUR TOOL
If your power tool becomes over heated, set the speed
to maximum and run no load for 2-3 minutes to cool
the motor. SDS-plus tungsten carbide drill bits should
always be used for concrete and masonry.
Mode for simultaneous
drilling and impacting of
concrete, Masonry
Mode for or drilling into steel,
wood and plastics
Mode for or chiseling
Mode for adjust the chuck
angle of chiseling
NOTE: Note：Select this
function mode first , adjust
the chuck angle to desired
direction. Then select the
function mode to " " , oper-
ate the chiseling work.
When drilling in metal, only use HSS drill bits in good
condition. Where possible use a pilot hole before
drilling a large diameter hole.

PROBLEM SOLUTION

1. REASONS FOR DIFFERENT CHARGING TIMES
Your charge time can be affected by many reasons
which are not defects in your product. If the battery
pack is only partly discharged it may be re-charged
in less than 1 hour. If the battery pack and ambient
temperature are very cold then re-charging may take
1-1.5 hours. If the battery pack is very hot it will not re-
charge because the internal temperature safety cutout
will prevent it. If the battery pack is very hot you must
remove your battery pack from the charger and allow
your battery pack to cool first to ambient temperature
and then recharging can be started. If you charge a
second battery pack immediately after the first then
the charger can be overheated. Always allow at least 15
minutes rest between battery pack charging.
2. REASONS FOR DIFFERENT BATTERY PACK
WORKING TIMES
Charging time problems, having not used a battery
pack for a prolonged time will reduce the battery pack
working time. This can be corrected after several charge
and discharge operations by charging & working with
your drill. Heavy working conditions such as large
screws into hard wood will use up the battery pack
energy faster than lighter working conditions. Do not
re-charge your battery pack below 0oC and above 30oC
as this will affect performance.

MAINTENANCE

Remove the battery pack from the tool before
carrying out any adjustment, servicing or
maintenance.
Your power tool requires no additional lubrication or
maintenance. There are no user serviceable parts in
your power tool. Never use water or chemical cleaners
to clean your power tool. Wipe clean with a dry cloth.
Always store your power tool in a dry place. Keep the
motor ventilation slots clean. Keep all working controls
free of dust. Occasionally you may see sparks through
the ventilation slots. This is normal and will not damage
your power tool.
ENVIRONMENTAL
PROTECTION
Disposal
The machine, its accessories and packaging
materials should be sorted for environmentally
friendly recycling.The plastic components are
labeled for categorized recycling.
