SAFETY I NSTRU CTI 0 NS
(For All Tools)
WARNING: WHEN USING ELECTRICTOOLS, BASICSAFETY
PRECAUTIONSSHOULD ALWAYS
BE FOLLOWEDTO REDUCE
THE RISK
OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
2. CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp
or wet locations. Keep work area well
lit. Don't expose power tools to rain.
Don't use tool
in presence of flammable liquids or gases.
3. KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool
or extension cord.
4. STORE IDLETOOLS. When not in use, tools should be stored in dry, and high
or locked-up place
- out of reach of children.
5. DON'T FORCETOOL. It will dothejob better and safer at the ratefor which
it was intended.
6. USE RIGHT TOOL. Don't force small tool or attachment to do thejob of a
heavy-dutytool. Don't usetool for purpose notintended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESS PROPERLY. Don't wear loose clothing or jewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering to contain long hair.
8. USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
9. DON'T ABUSE CORD. Never carry tool by cordor yank it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
IO. SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it frees both hands to operate tool.
11. DON'T OVERREACH. Keep proper footing and balance at all times.
12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspect tool cords periodically and if damaged, have repaired by
authorized service facility. Inspect extension cords periodically and replace
if damaged. Keep handles dry, clean,
and free from oil and grease.
13. DISCONNECTTOOLS. When not in use, before servicing, and when changing
accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed from tool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger onswitch.
Be sure switch is OFF when plugging in.
16. EXTENSION CORDS. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord will cause a drop in
line voltage resulting in
loss of power and overheating. Table 1 shows the
correct size to use depending on cord length and nameplate ampere rating.
If
in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

VOLTAGE WARNING: Before connecting the tooltoa power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source with voltage greater than that specified
for the tool can result
in SERIOUS INJURY to the user - as well as damage to
the tool.
If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.
For all grounded tools with American type plug.
GROUNDING INSTRUCTIONS: This tool should be grounded while in use to
protect the operator from electric shock. The tool is equipped
with a three-
conductor cord and three-prong grounding-type plug to fit the proper
grounding-type receptacle. The green (or green and yellow) conductor
in the
cord is the grounding wire. Never connect the green(or greenand yellow) wire
toa live terminal. Your
unit is for use on 115 volts and has a plug that looks
like Fig.
"A'.
An adapter Fig. "B" and "C" is available for connecting Fig. "A' type plugs
totwo-prongreceptacles. The green-colored rigidear, lug, etc., extending from
the adapter must be connected to a permanent ground, such as a properly
grounded outlet box.

ADDITIONAL SAFETY RULES
1. Wear a hard hat (safetyhelmet), safety glasses and/or face shield. It is also
highly recommended that you wear a dust mask, ear protectors and thickly
padded gloves.
2. Be sure the bit is secured in place before operation.
3. Under normaloperation, the tool is designedto producevibration. The screws
can come loose easily, causing a breakdown or accident. Check tightness
of screws carefully before operation.
4. Incold weather or when the tool has not been used for a long time, let the
tool warm upfor several minutes by operating
it under noload. This will loos-
en up the lubrication. Without proper warm-up, hammering operation is
difficult.
Be sure no one
is below when using the tool in high locations.
5. Always be sure you have a firm footing.
6. Hold the tool firmly with both hands.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool only when hand-held.
9. Do not point the tool at any one inthe area when operating. The bit could
fly out and injure someone seriously.
IO. When drilling or chipping intowalls, floors or wherever "live" electrical wires
may be encountered,
DO NOT TOUCH ANY METAL PARTS OF THE TOOL!
Hold the tool by the insulated grasping surfaces to prevent electric shock
if you drill or chip into a "live" wire.
11. Do not touch the bit or parts close to the bit immediately after operation;
they may be extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.

Bitgrease
Coat the bit shank head beforehand with
a small amount (about0.5- 1 g; 0.02-0.04 oz.)
of bit grease. This chuck lubrication assures smooth action and longer service life.
Installingor removingdrill bit
CAUTION:
Always be sure that the tool
is switched off and unplugged before installing or removing
the bit.
To install the bit, press the change ring in
the direction
of the arrow, align the key
groove on the bit shank with the red dot
and insert the bit. Now release the change
ring. If the change ring does not return to
its original position easily, turn the bit
slightly ineither direction.
To remove the bit, press the change ring in
the direction of the arrow and the bit will
slip out.

Adjustingdepth of drilling
Loosen the wing bolt and adjust the depth
gauge to the desired depth. After adjusting,
tighten the wing bolt.

Side grip (auxiliary handle)
The side grip swings around to either side,
allowing easy handling
of the tool in any
position. Loosen the side grip by turning
it
counterclockwise, swing it to the desired
position and then tighten
it by turning
clockwise.

Switch action
Too speed is increased by increasing pres-
sure on the trigger.
To start the tool, simply
pull the trigger.
Release the trigger to stop.
A speed control screw
is provided so that
maximum tool speed can be limited (vari-
able). Turn the speed control screw clock-
wise for higher speed, and counterclock-
wise for lower speed.

Hammer drillingoperation
Position the bit at the location for the
hole, then pullthe trigger.
Do not force the tool. Light pressure gives
best results. Keep the tool in position and
prevent
it from slipping away from the
hole.
Do not apply more pressurewhen the hole
becomes clogged with chips or particles.
Instead, run the tool
at an idle, then re-
move from the hole.
By repeating this
several times, the holewill be cleanedout.

Driving in anchor manually
The drill bit has a red marking at a point
corresponding to the anchor length.
So
drill to that depth.
Use the blow-out bulb
to clean out the
hole.
Put
a plug on the anchor and hammer it
into the concrete.

Dustcollector
Use the dust collector for safe, sanitary
overhead operations. Install the bit, then
attach the dust collector on the end by
turning and applying pressure.Then secure
it by turning the metal retainerclockwise.
CAUTION
:
Empty the dust collector of its contents
after drilling every
2 or 3 holes.

metal and up to
30 mm (1-3/16") inwood.
