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.
Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to safety
rules for the subject product. MISUSE or failure to
follow the safety rules stated in this instruction
manual may cause serious personal injury.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig. 1)
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. For continuous
operation, pull the switch trigger and then push in the lock
button. To stop the tool from the locked position, pull the
switch trigger fully, then release it.
Lighting up the lamps
For Model HR2460F (Fig. 2)
CAUTION:
• Do not look in the light or see the source of light
directly.
To turn on the lamp, pull the trigger. Release the trigger to
turn it off.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
Reversing switch action (Fig. 3)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• If the switch trigger can not be depressed, check to see
that the reversing switch is fully set to position
(A
side) or
(B side).
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or the
position
(B side) for counterclockwise rotation.
Selecting the action mode (Fig. 4)
This tool employs an action mode changing knob. Select
one of the two modes suitable for your work needs by
using this knob.
For rotation only, turn the knob so that the arrow on the
knob points toward the symbol on the tool body.
For rotation with hammering, turn the knob so that the
arrow on the knob points toward the
symbol on the
tool body.
CAUTION:
• Always set the knob fully to your desired mode symbol.
If you operate the tool with the knob positioned halfway
between the mode symbols, the tool may be damaged.
• Use the knob after the tool comes to a complete 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.
• Bits such as hole saw, which tend to pintch or catch
easily in the hole, are not appropriate for this tool. This
is because they will cause the torque limiter to actuate
too frequently.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side grip (auxiliary handle) (Fig. 5)
CAUTION:
• Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
Bit grease
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and longer
service life.
