• lead from lead‑based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from
chemically‑treated lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well‑ventilated
area, and work with approved safety equipment, such
as dust masks that are specially designed to filter out
microscopic particles.
Wear protective clothing and wash exposed areas
•
with soap and water. Allowing dust to get into your
mouth, eyes, or lie on the skin may promote absorption of
harmful chemicals. Direct particles away from face and body.
Use the appropriate dust extractor vacuum to remove
•
the vast majority of static and airborne dust. Failure
to remove static and airborne dust could contaminate the
working environment or pose an increased health risk to
the operator and those in close proximity.
Air vents often cover moving parts and should be
•
avoided. Loose clothes, jewelry or long hair can be caught
in moving parts.
An extension cord must have adequate wire size
•
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than
18 gauge. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. When
using more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier the cord.

Motor
Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating. These tools are factory tested; if
this tool does not operate, check power supply.
Soft Start Feature
The soft start feature allows the impact rate to build up more
slowly, thus preventing the chisel or point from "bouncing"
around on the masonry when starting up.
Active Vibration Control
The active vibration control neutralizes rebound vibration
from the hammer mechanism. Lowering hand and arm
vibration, it allows more comfortable use for longer periods
of time and extends the life of the unit.

ASSEMBLY AND ADJUSTMENTS


WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories. An
accidental start‑up can cause injury.

WARNING: To reduce the risk of personal injury,
ALWAYS operate the tool with the bail/loop style
auxiliary handle properly installed when using the tool
for horizontal applications. Failure to do so may result
in the bail/loop style auxiliary handle slipping during
tool operation and subsequent loss of control. Hold tool
with both hands to maximize control.
The bail/loop style auxiliary handle
of the housing and may be rotated 360˚ to permit right- or
left-hand use.
