GENERAL OPERATIONAL PRECAUTIONS
1.
Keep work area clean. Cluttered areas and benches
invite injuries.
2.
Consider work area environment. Don't expose
power tools to rain. Don't use power tools in
damp or wet locations. Keep work area well lit.
Don't use tool in presence of flammable liquids
or gases.
Power tools produce sparks during operation.
They also spark when switching ON/OFF. Never
use power tools in dangerous sites containing
lacquer, paint, benzine, thinner, gasoline, gases,
adhesive agents, and other materials which are
combustible or explosive.
3.
Guard against electric shock. Prevent body contact
with grounded surfaces. For example; pipes, ra-
diators, ranges, refrigerator enclosures.
4.
Keep children away. Do not let visitors contact
tool or extension cord. All visitors should be kept
away from work area.
5.
Store idle tools. When not in use, tools should
be stored in dry and high or locked-up place—
out of reach of children.
6.
Don't force tool. It will do the job better and safer
at the rate for which it was intended.
7.
Use right tool. Don't force small tool or attach-
ment to do the job of a heavy-duty tool. Don't
use tool for purpose not intended —for example
—don't use circular saw for cutting tree limbs
or logs.
8.
Dress properly. Do not wear loose clothing or
jewelry. They can be caught in moving parts.
Rubber gloves and non-skid footwear are recom-
mended when working outdoors. Wear protective
hair covering to contain long hair.
9.
Use eye protection. Also use face or dust mask
if cutting operation is dusty.
10.
Don't abuse cord. Never carry tool by cord or yank
it to disconnect from receptacle. Keep cord from
heat, oil and sharp edges.
11.
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.
12.
Don't overreach. Keep proper footing and balance
at all times.
13.
Maintain tools with care. Keep tools sharp and
clean for better and safer performance. Follow
instructions for lubricating and changing accesso-
ries. Inspect tool cords periodically and if dam-
aged, have repaired by authorized service center.
Inspect extension cords periodically and replace
if damaged. Keep handles dry, clean, and free
from oil and grease.
14.
Disconnect tools. When not in use, before serv-
icing, and when changing accessories, such as
blades, bits, cutters.
15.
Remove adjusting keys and wrenches. Form habit
of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
16.
Avoid unintentional starting. Don't carry plugged-
in tool with finger on switch. Be sure switch is
off when plugging in.
17.
Outdoor use extension cords. When tool is used
outdoors, use only extension cords intended for
use outdoors and so marked.
18.
Stay alert. Watch what you are doing. Use com-
mon sense. Do not operate tool when you are tired.
19.
Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will
operate properly and perform its intended func-
tion. Check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and
5
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced by an authorized
service center unless otherwise indicated else
where in this handling instructions. Have defective
switches replaced by authorized service center. Do
not use tool if switch does not turn it on and off.
20.
Use the power tools only for applications specified
in the Handling Instructions.
21.
To avoid personal injury, use only the accessories
or attachment recommended in these handling
instructions or in the HITACHI catalog.
22.
Let only the authorized service center do the
repairing.
The manufacturer will not be responsible for any
damages or injuries caused by repair by un-
authorized persons or by mishandling of the tool.
23.
To ensure the designed operational integrity of
power tools, do not remove installed covers or
screws.
24.
Do not touch movable parts or accessories unless
the power source has been disconnected.
25.
Use your tool at lower input than specified on the
nameplate; otherwise, the finish may be spoiled
and working efficiency reduced by motor over-
load.
26.
Do not wipe plastic parts with solvent. Solvents
such as gasoline, thinner, benzine, carbon tetra-
chloride, alcohol, ammonia and oil containing
chloric annex may damage and crack plastic parts.
Do not wipe them with such solvent. Wipe plastic
parts with a soft cloth lightly dampened with soapy
water.
27.
Use only genuine HITACHI replacement parts.
28.

dling instructions only for authorized servicing.
PRECAUTIONS ON USING HAMMER DRILL
1. Wear earplugs to protect your ears during operation.
2. Do not touch the bit during or immediately after
operation. The bit becomes very hot during
operation and could cause serious burns.
3. Before starting to break, chip or drill into a wall,
floor or ceiling, thoroughly confirm that such items
as electric cables or conduits are not buried inside.
4. Always hold the body handle and side handle of
the power tool firmly. Otherwise the counterforce
produced may result in inaccurate and even
dangerous operation.
