SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to hammer safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal
injury.
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 tools 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 tool "live" and could give the operator
an electric shock.
4. Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun
glasses are NOT safety glasses. It is also
highly recommended that you wear a dust
mask and thickly padded gloves.
5. Be sure the bit is secured in place before
operation.
6. Under normal operation, the tool is designed
to produce vibration. The screws can come
loose easily, causing a breakdown or accident.
Check tightness of screws carefully before
operation.
7. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
8. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Do not operate
unnecessarily.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.

Speed change
Fig.2
The blows per minute can be adjusted just by turning the
adjusting dial. This can be done even while the tool is
running. The dial is marked 1 (lowest speed) to 5 (full
speed).
Refer to the table below for the relationship between the
number settings on the adjusting dial and the blows per
minute.

NOTE:
Blows at no load per minute becomes smaller than
•
those on load in order to reduce vibration under no
load, but this does not show trouble. Once
operation starts with a bit against concrete, blows
per minute increase and get to the numbers as
shown in the table. When temperature is low and
there is less fluidity in grease, the tool may not
have this function even with the motor rotating.
CAUTION:
The speed adjusting dial can be turned only as far
•
as 5 and back to 1. Do not force it past 5 or 1, or
the speed adjusting function may no longer work.
