OVERLOAD PROTECTION
If the tool insert becomes caught or jammed, the drive
to the drill spindle is interrupted. Because of the forces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
WORKING HINTS FOR
YOUR HAMMER
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. 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
tool. 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 0 o C and above 30 o C as this will affect
performance.
MAINTENANCE
Remove the battery pack 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

materials should be sorted for environmentally
friendly recycling.
