Safety Warnings - Hitachi CR 10DL Handling Instructions Manual

c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another.
Shorting the battery terminals together may cause
burns or a fi re.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
6) Service
a) Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts.
This will ensure that the safety of the power tool is
maintained.
PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of
children and infi rm persons.
CORDLESS RECIPROCATING SAW

SAFETY WARNINGS

1. Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
ADDITIONAL SAFETY WARNINGS
1. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
2. Never disassemble the rechargeable battery and
charger.
3. Never short-circuit
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
4. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
5. When cutting in wall, fl oor or ceiling, check for buried
electric power cord, etc.
6. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
7. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or infl ammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
8. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Please leave
it without using it for approximately 15 minutes.
9. Wear earplugs to protect your ears during operation.
10. Do not touch the blade during or immediately after
operation. The blade becomes very hot during operation
and could cause serious burns.
11. Always hold the housing of the power tool fi rmly.
Otherwise the counterforce produced may result in
inaccurate and even dangerous operation.
12. Remove the battery from tool or place the switch in the
locked or off position before making any adjustments,
changing accessories, storing, carrying, or when not
using the tools.
the rechargeable battery.
13. Mounting and dismounting the blade
○ Be absolutely sure to keep the switch turned off and the
battery removed to prevent any accident.
○ Pull the back of the saw blade two or three times by hand
and check that the blade is securely mounted. When
pulling the blade, you will know it is properly mounted if it
clicks and the lever moves slightly. (Fig. 3)
○ When pulling the saw blade, be absolutely sure to pull it
from the back. Pulling other parts of the blade will result
in an injury.
○ If the broken saw blade is hidden inside the small slit,
hook the broken blade using a tip of another saw blade
and take it out. (Fig. 4)
○ After use, blow away sawdust, earth, sand, moisture,
etc., with air or brush them away with a brush, etc., to
ensure that the blade mount can function smoothly.
○ As shown in Fig. 5, carry out lubrication around the
blade holder on a periodic basis by use of cutting fl uid,
etc.
○ Continued use of the tool without cleaning and lubricating
the area where the saw blade is installed can result in
some slack movement of the lever due to accumulated
sawdust and chips. Under the circumstances, pull a
rubber cap provided on the lever in the direction of an
arrow mark as shown in Fig. 5 and remove the rubber
cap from the lever. Then, clean up the inside of the
blade holder with air and the like and carry out suffi cient
lubrication.
The rubber cap can be fi tted on if it is pressed fi rmly onto
the lever. At this time, make certain that there exists no
clearance between the blade holder and the rubber cap,
and furthermore ensure that the saw-blade-installed
area can function smoothly.
○ Do not use any saw blade with a worn-out blade hole.
Otherwise, the saw blade can come off , resulting in
personal injury.
14. When setting the base position, be absolutely sure to
keep the switch turned off and the battery removed to
prevent any accident.
15. Make sure that the battery is installed fi rmly. If it is at all
loose it could come off and cause an accident.
16. Do not carry tools with your fi nger on the switch. A
sudden startup can result in an unexpected injury.
17. Be careful not to let sawdust, earth, moisture, etc., enter
the inside of the machine through the plunger section
during operation. If sawdust and the like accumulate in
the plunger section, always clean it before use.
18. During use, press the base fi rmly against the workpiece.
19. Select a saw blade of the most appropriate length.
Ideally, the length protruding from the base of the saw
blade after subtracting the stroke quantity should be
larger than the material.
If you cut a large pipe, large block of wood, etc., that
exceeds the cutting capacity of a blade; there is a risk
that the blade may contact with the inner wall of the pipe,
wood, etc., resulting in damage. (Fig. 8)
20. Never apply any unreasonable force to the saw blade
when cutting. Doing so can easily break the blade.
21. The motor can be locked sometimes, depending
on the combination of the material to be cut and the
blade. Whenever the motor gets locked, switch it off
immediately.
22. Fasten a workpiece fi rmly before operation. (Fig. 9)
23. When cutting metallic materials, use proper machine
oil (turbine oil, etc.). When not using liquid machine oil,
apply grease over the workpiece.
The service life of the saw blade will be drastically
shortened if you don't use machine oil.
24. Delay the feed speed when cutting the material into
small circular arcs. An unreasonably fast feed may break
the blade.
