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
provided in the green tube (Fig. 1).
(2) To attach the tool (SDS max shank), insert it into
the hole until it contacts the innermost end of the
hole as illustrated in Fig. 2.
If you continue to turn the tool with slight pressure,
you can feel a spot where there is a hitch. At that
spot, pull the grip to the direction of an arrow mark
and insert the tool all the way until it hits the
innermost end.
Releasing the grip reverts the grip and secures the
tool in place.
(3) To remove the tool, fully pull the grip in the direction
of the arrow and pull out the tool.
HOW TO USE THE ROTARY HAMMER
1. How to drill holes (Fig. 3)
(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 crush (Fig. 4)
By applying the drill bit tip to the chiseling or
crushing position, operate the rotary hammer by
utilizing its empty weight.
Forcible pressing or thrusting is unnecessary.
3. When drilling at "rotation + striking":
CAUTION:
If you switch the selector lever during motor rotation,
the tool can start to rotate abruptly, resulting in
unexpected accidents. Be sure to switch the selector
lever when the motor is at a complete stop.
