PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a power receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, which could cause a
serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be kept
as short as practicable.
4. How to install tool
NOTE
For tools such as a bull point and a cold chisel, use
only Hitachi genuine parts.
(1) Clean, then smear the tool shank with the grease or
machine oil (Fig. 1).
(2) Press the push button, slightly lift the tool retainer in
the direction of arrow A as shown in Fig. 2 to hook
the tool retainer edge with the push button and
engage the push button.
(3) Release your finger from the push button and further
lift the tool retainer in the direction of arrow A .
NOTE
First time when the tool retainer is lifted, remove your
finger from the push button. If the push button is kept
pressed, the edge of the tool retainer comes in contact
with your finger and the tool retainer cannot be lifted.
(4) Fully insert the tool shank into the hexagonal hole in
the front cover.
(5) Return the tool retainer to secure the tool.
(6) Pull the tool to make sure it is locked completely.
NOTE
Remove in the reverse order of installation.
WHEN THE PUSH BUTTON DOES NOT
OPERATE SMOOTHLY
When the push button does not operate smoothly, please
remove dirt from the inside through the outlet using a
wire, etc. Then lubricate lubricating oil and push the push
button several times to make it operate smoothly. (Fig.
3)
HOW TO USE THE ROTARY HAMMER
NOTE: Ensure that the wing bolt in the side handle is
properly tightened before using the tool.
1. How to drill holes (Fig. 4)
(1) Pull the switch trigger after applying the drill bit tip to
the drilling position.
(2) It is unnecessary to forcibly press the rotary hammer
main body. It is sufficient to slightly press the rotary
hammer to an extent that shavings are freely
discharged.
CAUTION
Although this machine is equipped with a safety
clutch, if the drill bit becomes bound in concrete or
other material, the resultant stoppage of the drill bit
could cause the machine body to turn in reaction.
Ensure that the main handle and side handle are
gripped firmly during operation.
2. How to chisel or demolish (Fig. 5)
By applying the drill bit tip to the chiseling or
demolishing position, operate the rotary hammer by
utilizing its empty weight.
Forcible pressing or thrusting is unnecessary.
3. Warming up (Fig. 6)
The grease lubrication system in this unit may require
warming up in cold regions.
Position the end of the bit so makes contact with the
concrete, turn on the switch and perform the warming
up operation. Make sure that a hitting sound is
produced and then use the unit.
