those recommended in the instruction manual, may present
a risk of personal injury. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller tool and may
burst.
Check before Use
1. Connection to Power Supply
2. Extension Cord
Use an extension cord if the
distance to the power source
requires its use. Extension cord
must be of appropriate thickness
and length for the supply of
electric current. Too thin or too long cord will cause voltage to
drop reducing the motor power. Use it as short as possible.
If the cord is damaged, have it repaired or replaced at A/S
center immediately.
3. Maintenance and Checking of Work Area
Work area must be checked using CAUTIONs in this manual
to ensure it provides appropriate environment.
4. Power Supply Check
Make sure that the power supply complies the requirements
described in the name plate on the Electric Hammer Drill.
5. Switch Status Check
if the power plug is connected when the power switch is
in ON position, sudden rotation of the moving parts of the
Electric Hammer Drill may cause accident.
Check if the switch lever returns to its original position when
it is pushed and pulled.
