Prior To Operation; How To Use - Hitachi CR14DSL Handling Instructions Manual

PRIOR TO OPERATION

1. Mounting the blade
This unit employs a detachable mechanism that enables
mounting and removal of saw blades without the use of a
wrench or other tools.
(1) Turn on and off the switching trigger several times so
that the lever can jump out of the front cover completely.
Thereafter, turn off the switch and remove the battery.
(Fig. 5)
CAUTION
Be absolutely sure to keep the switch turned off and the
battery removed to prevent any accident.
(2) Push the lever in the direction of the arrow mark shown in
Fig. 6 marked on the lever (Fig. 6).
(3) Insert the saw blade all the way into the small slit of the
plunger tip with the lever pushing. You can mount this
blade either in the upward or downward direction (Fig. 7,
Fig. 8).
(4) When you release the lever, the spring force will return
the lever to the correct position automatically (Fig. 9).
(5) 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. 10)
CAUTION
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.
2. Dismounting the blade
(1) Turn on and off the switching trigger several times so
that the lever can jump out of the front cover completely.
Thereafter, turn off the switch and remove the battery.
(Fig. 5)
CAUTION
Be absolutely sure to keep the switch turned off and the
battery removed to prevent any accident.
(2) After you have pushed the lever in the direction of the
arrow mark shown in Fig. 6 and secured it, turn the blade
so it faces downward. The blade should fall out by itself.
If the blade doesn't fall out, pull it out by hand.
CAUTION
Never touch the saw blade immediately after use. The
metal is hot and can easily burn your skin.
WHEN THE BLADE IS BROKEN
Even when the saw blade is broken and remains inside
the small slit of the plunger, it should fall out if you push
the lever in the direction of the arrow mark, and face the
blade downward. If it doesn't fall out itself, take it out
using the procedures explained below.
(1) If a part of the broken saw blade is sticking out of the
small slit of the plunger, pull out the protruding part and
take the blade out.
(2) 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. 11)
MAINTENANCE AND INSPECTION OF SAW BLADE
MOUNT
(1) 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.
(2) As shown in Fig. 12, carry out lubrication around the
blade holder on a periodic basis by use of cutting fl uid,
etc.
NOTE:
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. 13 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.
CAUTION
Do not use any saw blade with a worn-out blade hole.
Otherwise, the saw blade can come off , resulting in
personal injury. (Fig. 14)
3. Moving the base
Loosen the set screw and move the base forward, as
shown in Fig. 15, Fig. 16. Tighten the set screw slightly,
ensure the base does not move back and forth, and
fi rmly tighten the set screw. Ensure that the base does
not contact the blade.
4. Confi rm that the battery is mounted correctly

HOW TO USE

CAUTION
○ Do not carry tools with your fi nger on the switch. A
sudden startup can result in an unexpected injury.
○ 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 (refer to
Fig. 5).
○ Do not remove the front cover.
Be sure to hold the body from the top of the front cover
(refer to Fig. 5).
○ During use, press the base against the material while
cutting.
Vibration can damage the saw blade if the base is not
pressed fi rmly against the workpiece.
Furthermore, a tip of the saw blade can sometimes
contact the inner wall of the pipe, damaging the saw
blade.
○ 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 (see Fig. 18 and Fig. 20).
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. 19, Fig. 21).
1. Switch operation
(1) Lock-off button
The tool is equipped with a lock-off button. To activate
the trigger lock, move the button to the right position.
Move the button to the left to operate the tool. (Fig. 17)
Always lock the switch when carrying or storing the tool
eliminate unintentional starting.
(2) Trigger switch
This tool is equipped with a variable speed controlled
trigger switch. The tool can be turned "ON" or "OFF" by
squeezing or releasing the trigger. The blade plunger
stroke rate can be adjusted from the minimum to
maximum nameplate stroke rate by the pressure you
apply to the trigger. Apply more pressure to increase the
speed and release pressure to decrease speed.
