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 tools 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, radiators,
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 tools. 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 attachment
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 recommended when
working outdoors. Wear protective hair covering to
contain long hair.
9. Use safety glasses. Also use face or dust mask if
cutting operation is dusty.
10. Don’t abuse cord. Never carry tool by cord or yank it
do 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 accessories. Inspect tool
cords periodically and if damaged, 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 servicing,
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 common
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 function. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and 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 elsewhere in this instruction manual. Have
defective switches replaced by authorized service
center. Do not use tool if switch does not turn it on and
off.
20. Do not use power tools for applications other than
those specified in the Handling Instructions.
21. To ensure the designed operational integrity of power
tools, do not remove installed covers or screws.
22. Do not touch movable parts or accessories unless the
power source has been disconnected.
23. Use your tool at lower input than specified on the
nameplate; otherwise, the finish may be spoiled and
working efficiency reduced due to motor overload.
24. Do not wipe plastic parts with solvent. Solvents such
as gasoline, thinner, benzine, carbon tetrachloride,
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.
25. Consult an authorized Service Agent in the event of
power tool failure.
26. Use only genuine HITACHI replacement parts.

PRECAUTIONS ON USING HAMMER DRILL
䡬
Wear earplugs to protect your ears during operation.
䡬
Do not touch the bit during or immediately after
operation. The bit becomes very hot during operation
and could cause serious burns.
䡬
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.
䡬
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.
