5.
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.
6.
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.
7.
Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8.
Hold the tool firmly with both hands.
9.
Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
13. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

FUNCTIONAL DESCRIPTION
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before adjusting or checking function on
the tool.
Switch action
CAUTION:
•
Before plugging in the tool, always check to see
that the switch trigger actuates properly and returns
to the "OFF" position when released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
Torque limiter
The torque limiter will actuate when a certain torque level
is reached. The motor will disengage from the output
shaft. When this happens, the bit will stop turning.
CAUTION:
•
As soon as the torque limiter actuates, switch off
the tool immediately. This will help prevent
premature wear of the tool.
•
Hole saws, core bits, diamond core bits, etc. cannot

be used with this tool. They tend to pinch or catch
easily in the hole. This will cause the torque limiter
to actuate too frequently.
ASSEMBLY
