DEMOLITION HAMMER SAFETY
WARNINGS
1. Wear ear protectors.
Exposure to noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
3. Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
ADDITIONAL SAFETY WARNINGS
1. Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
2. Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
3. When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. RCD
The use of a residual current device with a rated residual
current of 30mA or less at all times is recommended.
5. Do not touch the bit during or immediately after
operation. The bit becomes very hot during operation
and could cause serious burns.
6. Before starting to break, chip or drill into a wall, fl oor or
ceiling, thoroughly confi rm that such items as electric
cables or conduits are not buried inside.
7. Wear a mask when turning your head upward.
8. Properly set the bit holder.
9. At the start of work, confi rm screw tightening.

How to use the demolition hammer *
Replacing carbon brushes
Selecting accessories
* Operate this Demolition Hammer by utilizing its empty
weight. The performance will not be better even if it is
pressed or thrust forcibly against the work surface.
Hold this Demolition Hammer with a force just suffi cient
to counteract the reaction.
This Demolition Hammer is equipped with a spring
cushion on the handle so that chipping vibration is not
conveyed to the operator.
Operate this Demolition Hammer without forcing the
handle too strongly.
CAUTION
Sometimes the power tool does not begin the striking
stroke even when the motor rotates because the oil has
become thick.
If the power tool is used at low temperatures or if it is
used after a long idle time, this Demolition Hammer
should be kept running in for about fi ve minutes in order
to warm it up.
